The Complete Condo Buying Checklist (2026)

Buying a condominium is not the same as buying a house. When you buy a house, your due diligence is focused on the property. When you buy a condo, your due diligence has to cover two things: the unit itself, and the financial and legal condition of the association that co-owns the building and grounds with every other unit holder.

The association is not a landlord you can ignore. It has the legal authority to levy monthly dues, impose special assessments for major repairs, and in most states, place a lien on your unit if you fall behind. Its financial decisions — reserve funding, insurance coverage, deferred maintenance — directly affect your property value, your monthly costs, and your ability to sell or refinance in the future.

Most buyers treat condo due diligence as a document-signing exercise. They receive a stack of disclosure materials, initial the acknowledgment page, and rely on their agent to flag anything unusual. That process produces buyers who are surprised by special assessments, insurance shortfalls, and structural-compliance costs that were visible in the documents all along.

This checklist organizes the due diligence process into four phases that align with how a typical real estate transaction unfolds. Some of these questions can be answered before you make an offer. Others require access to the full resale package that arrives after contract execution. A few require professional review — an attorney, a reserve specialist, or a document-review service — to interpret accurately.

The goal is not to make buying a condo more difficult. It is to make the risks visible before you commit, so the price you pay reflects the building you are actually buying.

Phase 1: Before You Make an Offer

Most buyers skip pre-offer due diligence on condos entirely. That is a mistake with real consequences. The information available before you write your offer number — fee levels, known pending assessments, market comparables adjusted for association financial health — directly affects what a unit is worth to you. You cannot negotiate on information you do not have.

Setting your search filters

Before you evaluate any specific unit, set parameters that filter out buildings where the financial fundamentals are already broken. This is not pessimism; it is efficient use of your time.

Age and reserve-funding regime. In Florida, a building 30 years or older (25 years within three miles of the coast) is subject to the Milestone Inspection and Structural Integrity Reserve Study requirements enacted in the wake of the 2021 Champlain Towers collapse. Buildings in that cohort — and there are many: over 16,000 Florida associations covering approximately 900,000 units were at or beyond 30 years of age as of late 2024 — are working through a combination of mandatory inspections, reserve catch-up contributions, and in many cases, special assessments. That is not disqualifying, but it requires specific due diligence steps that are different from reviewing a newer building.

In Texas, there is no statutory reserve requirement. In Arizona, there is no requirement to fund reserves, though associations with 50 or more units must disclose their reserve balances and any existing reserve study to buyers under ARS 33-1260. In both states, reserve adequacy is a voluntary function of board governance, which means the variance between well-run and poorly-run associations is wider than in states with mandatory funding frameworks.

Rental cap and owner-occupancy ratio. Fannie Mae and Freddie Mac have project-eligibility requirements that include limits on the percentage of units that are investor-owned. A building where more than a certain percentage of units are rented may not qualify for conventional financing, which restricts your buyer pool when you sell and may require non-conventional financing when you buy — typically at higher cost. Ask the listing agent for the current owner-occupancy ratio before writing an offer.

Pending litigation. Buildings with active significant litigation — structural claims, developer warranty disputes, personal-injury suits — carry elevated financial risk. The litigation may produce a judgment that requires a special assessment to satisfy, or may drive up insurance costs. In Florida, HB 1021 (2024) strengthened the association's record-keeping and disclosure obligations, making this information more reliably accessible. In any state, a listing agent who cannot or will not answer whether the association has pending litigation is a reason to request documents before proceeding.

Documents to request early

You will not receive the full resale package until after you execute a contract in most states. But you can often get partial information informally through the listing agent, particularly for buildings where the seller or their agent is forthcoming. Ask for:

• The current year's operating budget
• The most recent reserve study (or reserve study summary)
• Any pending or approved special assessment disclosure
• The current master insurance certificate

Even if only one or two of these are available before offer, the operating budget alone can answer several key questions. What is the monthly fee relative to comparable buildings? What percentage of the budget is going to reserves? Does the reserve contribution line suggest that the association is adequately funding for capital expenses, or is it running on thin margins?

Comparing fees against the building's actual cost structure

A monthly fee only means something in the context of what it is paying for. The relevant benchmarks are not competing listings — they are the building's actual operating and capital costs.

For the reserve contribution specifically, Fannie Mae uses a minimum floor of 10% of the association's annual budget going to reserves as a condition for purchasing conventional loans on units in the building. That is a minimum for mortgage eligibility, not a statement of strong funding. A building that barely clears 10% may still be significantly underfunded relative to what its reserve study recommends.

Look at the full picture: if the operating budget shows insurance consuming 30% of revenues in a coastal Florida building, and reserves consuming 8%, and the reserve study recommends 20% to stay on track, the math does not work. Either dues increase, or a special assessment closes the gap.

Arizona's average monthly HOA fee runs approximately $448 — among the highest in the country — reflecting the state's amenity-heavy master-planned development model. Texas metro fees tend to run lower. Florida fees have been rising across the board as reserve-funding mandates take effect. In all three states, the right question is not whether the fee looks high or low but whether the number behind the fee covers what the building actually needs.

Initial neighborhood and building risk screening

Condo due diligence includes physical risk factors that affect insurance costs and long-term capital needs. For a coastal Florida or Texas building, flood zone designation and wind exposure are material. FEMA flood map classification affects whether flood insurance is required, what it costs, and what coverage gap may exist between the master policy and individual unit coverage.

In Texas, the Texas Windstorm Insurance Association provides wind and hail coverage in designated coastal counties. Average TWIA premiums ran approximately $2,877 per year as of March 2026. For inland Texas buildings, private wind coverage is available but increasingly expensive: average homeowners' insurance premiums in Texas reached approximately $3,291 by 2024, following a roughly 22% increase in 2023 alone. Those costs flow into the association's master policy and, ultimately, into dues.

For Arizona buildings, wildfire proximity is the analogous risk factor. Arizona's homeowners' insurance market has remained more stable than Florida or Texas, with average premiums around $2,104 in 2025, but wildfire and microburst exposure can push individual building costs meaningfully above that average and affect insurability for some older or poorly-maintained complexes.

Lender pre-approval considerations for condo loans

Conventional condo financing involves an additional step that does not exist for single-family purchases: the lender's project review. Fannie Mae and Freddie Mac guidelines require lenders to evaluate the condominium project — not just the borrower — before they can sell the loan on the secondary market. This review checks:

• Whether the building is in active litigation
• Whether the association is adequately funded for reserves
• Whether the owner-occupancy rate meets the guidelines
• Whether there are any outstanding structural findings from required inspections

Buildings that fail this review may be eligible only for portfolio loans or government-backed financing, both of which typically carry higher rates or require larger down payments. If your agent says a building is "warrantable" or "non-warrantable," they are describing its status under these guidelines. Ask your lender to tell you upfront whether any buildings you are seriously considering have known project-eligibility issues. That conversation is worth having before you write an offer, not after you are in escrow.

Phase 2: During the Offer Period

Once you have a ratified contract, the clock starts on your inspection and document review period. This window — its length varies by state and contract, but is typically five to fifteen calendar days — is when the full resale package arrives and when you have the right to cancel without penalty. Use every day of it.

What the seller is contractually required to provide

The scope of what a seller must provide varies by state, but the floor in most markets includes:

• The declaration of condominium
• Bylaws and rules and regulations
• The most recent operating budget
• The most recent audited or reviewed financial statements
• The reserve study
• The last 12 to 24 months of meeting minutes
• The resale certificate or estoppel certificate
• Any pending special assessment disclosure

In Florida, the statutory disclosure framework under Florida Statute 718.503 requires that sellers provide a specific set of documents, and buyers have a right to cancel the contract within a defined window after receiving them. The Florida disclosure summary is a checklist that tells you what the seller is affirmatively representing — it is not a substitute for reviewing the underlying documents.

In Texas, SB 711 (effective September 2025) requires condominium associations with 60 or more units to maintain a website publishing their declarations, bylaws, and budgets. The resale certificate process in Texas is governed by Chapter 82 of the Texas Property Code; under SB 711, the fee for a resale certificate is capped at $375.

Reading the resale package within your inspection period

A typical resale package runs to several hundred pages. Reading it efficiently requires knowing which sections carry the most risk for your specific situation.

The reserve study is the first document to open. Find the percent-funded figure — the ratio of current reserves to what the study says should have been accumulated by this point in the components' life cycles. Below 30% in a building older than 20 years is a serious concern. Below 50% warrants a direct conversation about what the funding plan calls for over the next three to five years. The Champlain Towers South association — whose Surfside building collapsed in 2021 — held approximately $706,000 in reserves against a projected capital need of approximately $10.3 million, representing roughly 6.9% funding. That was not invisible in the documents; it was there to be found.

Then compare the reserve study's recommended annual contribution to the actual reserve contribution line in the operating budget. If the study recommends $180,000 per year and the budget shows $90,000, the gap is real and it is growing. Either it closes through dues increases or it materializes as a special assessment.

The operating budget tells you how the current fee is allocated. The three buckets to evaluate are operating expenses, insurance, and reserves. Insurance is the line item most likely to move dramatically in the near term, particularly in Florida and Texas. Look for any line items marked "deferred," "TBD," or "pending" — those signals mean the board is aware of a cost it has not yet funded.

The financial statements show you what actually happened versus what the budget projected. Look at both the operating fund and the reserve fund as separate balances. Then read the notes to the financial statements. Auditors are required to disclose significant uncertainties — pending litigation, underfunded obligations, loans against reserves. The summary balance sheet will not always surface these; the notes will.

The meeting minutes are the leading-indicator document. They tell you what the board has been discussing before problems become formal votes. Read the last 24 months. Look for: recurring repair discussions that have been "tabled," references to structural engineer engagements or reports, attorney retainers, discussion of insurance renewal difficulties, or any mention of a pending assessment vote that may not have closed before the listing. A repair that has been on the agenda four times and not addressed is not a minor matter.

Cross-checking budget against meeting minutes

The budget and the minutes should tell a consistent story. When they do not, the discrepancy is itself a signal.

The most common misalignment: meeting minutes that reference a significant upcoming expense — a roof replacement, a parking deck repair, a boiler replacement — but a current-year budget that has no reserve line item or capital expenditure allocation for it. The board knows the cost is coming; the budget does not reflect it. That gap either closes through an assessment or it gets deferred again. Neither outcome is invisible in the documents once you know to look.

Cross-referencing budgets with meeting minutes is covered in depth in a separate article on cross-referencing budgets with minutes.

Verifying special-assessment status

A special assessment disclosure is one of the most consequential documents in the package, and also one of the most frequently misread. There are three distinct categories of assessment status that require separate verification:

1. Active assessments — approved by the board, currently being collected. These should appear in the estoppel or resale certificate and in the budget. They are the most visible.

2. Approved but not yet billed assessments — voted by the board but not yet invoiced to owners. These may or may not appear in the resale certificate depending on timing. Ask the seller directly whether any assessment has been voted but not yet billed.

3. Foreseeable but not yet voted assessments — visible in the reserve study and meeting minutes but not yet formally approved. These are the most dangerous category for buyers who do not read the documents carefully. An association at 18% funded, with a major roof inspection due next year and a building that has never had a special assessment, is not a safe building — the assessment just has not been voted yet.

When to walk away

Walking away during the inspection period is a legitimate due-diligence outcome, not a failure. The conditions that most clearly support cancellation:

• A reserve study showing funding below 20% in a building over 25 years old, with no credible funded plan
• A meeting minutes record that documents deferred structural repairs across multiple board cycles
• An active structural inspection finding with unresolved Phase II or remediation status
• An unanswered question about a pending assessment that the seller or management company will not confirm
• A lender project review that has flagged the building as non-warrantable without an acceptable financing alternative
• Master insurance that is inadequate for the building's actual exposure — particularly in coastal markets

Price concessions can compensate for some of these conditions. They cannot compensate for all of them. An under-reserved building does not become adequately reserved because you paid less for the unit. The association's capital obligations are independent of your purchase price.

Phase 3: In Escrow

Once you have cleared the inspection period, the transaction moves into escrow. Due diligence continues — this phase involves formal documentation that establishes your financial and legal standing at closing. Several of these steps happen in parallel and require coordination between your lender, your attorney or title company, and the association.

The estoppel / resale certificate

The estoppel certificate (Florida terminology) or resale certificate (Texas) is a formal document prepared by the association or its management company that certifies the financial status of the specific unit you are buying at a specific point in time. It is distinct from the broader resale package.

In Florida, the estoppel certificate rules are governed by Florida Statute 718.116(8). Key provisions: the association must provide the certificate within 10 business days of the request; the fee is capped at $250 for standard processing and $400 for expedited; the certificate has a 30-day shelf life — if your closing is delayed more than 30 days after the certificate was issued, a new one must be obtained.

The estoppel confirms the current monthly assessment amount, any amounts past due on the unit, and any approved special assessments. Its limitation is timing: a special assessment voted after the certificate date but before your closing will not appear on it. This is why the direct question to the seller about pending assessments — covered in Phase 2 above — is not redundant.

In Texas, the resale certificate is governed by Chapter 82 of the Texas Property Code and the related provisions updated by SB 711 (2025). The $375 fee cap applies.

Master policy and certificate of insurance verification

The association's master insurance policy covers the building structure and common elements. For a buyer, the questions are:

What does the master policy cover? There are two models: bare-walls coverage (only the structure itself, not interior fixtures) and all-in coverage (including original fixtures and finishes inside units). The distinction determines what your individual HO-6 policy needs to cover. The declaration typically specifies which model applies.

What is the deductible structure? Many master policies — particularly in Florida and coastal Texas — carry wind deductibles expressed as a percentage of the insured building value rather than a flat dollar amount. On a $15 million building with a 5% wind deductible, the association's out-of-pocket exposure before insurance responds is $750,000. If reserves cannot absorb a gap of that size, a windstorm event becomes a special assessment event.

Who is the carrier and is the policy in force? Obtain the certificate of insurance and confirm the carrier, the policy effective date, and that the policy is current. In Florida's tight insurance market, some associations have experienced coverage gaps or mid-term cancellations in recent years. A certificate of insurance dated more than 90 days ago in a Florida transaction warrants confirmation that coverage has not lapsed.

A separate article covers the patterns to watch for when reviewing the master insurance certificate in detail at insurance summary red flags.

Title and lien search

The title search on a condo unit covers both the unit itself and its standing with the association. A thorough search will surface:

• Any outstanding assessment liens placed by the association on the unit
• Any mechanic's liens from contractors the owner or association has not paid
• Prior judgments or tax liens against the seller
• Any recorded notice of special assessment against the unit

In most transactions, title insurance is required by the lender and protects the lender's interest in the property. An owner's title policy — typically offered at modest additional cost — extends that protection to you as the buyer. In a condo transaction where the association's lien priority and the seller's payment history are both variables, an owner's policy is generally worth the cost.

Arizona's SB 1494 (2025) revised the foreclosure threshold for association liens to $10,000 or 18 months of delinquency — meaning associations can no longer pursue foreclosure over modest delinquencies as easily as before. But a lien is still a lien; it will appear in the title search and must be resolved before or at closing.

Lender's project review (Fannie Mae / Freddie Mac eligibility)

If you are financing with a conventional loan, your lender will conduct a project review of the condominium association during escrow. This is separate from the appraisal and the standard underwriting of your individual creditworthiness. The project review evaluates the association against Fannie Mae and Freddie Mac guidelines.

The review typically includes:

• The association's reserve contribution as a percentage of the budget (the 10% floor as a minimum adequacy benchmark)
• Owner-occupancy ratio (typically at least 50% of units must be owner-occupied for standard warrantable eligibility)
• Percentage of units owned by any single investor (concentration limits apply)
• Active or pending litigation involving the association
• Any outstanding structural findings or required inspection results — in Florida, this includes the Milestone Inspection status

If the building does not meet these standards, the loan may require a different structure or may not be available on conventional terms at all. This is not hypothetical for Florida buildings: some older buildings working through Milestone Inspection results or reserve compliance have encountered project-approval difficulties during this period. Knowing before you go into escrow — by asking your lender about known eligibility issues for specific buildings — prevents surprises at a point in the transaction when they are most disruptive.

Final document confirmation

Before closing, confirm that you have received and reviewed all required disclosure documents and that the estoppel or resale certificate reflects the current state of affairs. A checklist for this final confirmation:

1. Declaration of condominium, bylaws, and rules — received and reviewed
2. Operating budget (current year) — received and reviewed
3. Reserve study (most recent) — received and reviewed; percent-funded figure noted
4. Financial statements (most recent) — received and reviewed; auditor's notes read
5. Meeting minutes (24 months) — received and reviewed; no unresolved material issues
6. Estoppel or resale certificate — dated within 30 days of closing; no undisclosed assessments
7. Master insurance certificate — current, carrier confirmed, deductible structure noted
8. Title search — no outstanding assessment liens or judgment liens on the unit
9. Lender project review — warrantable status confirmed or financing alternative confirmed
10. Pending special assessment confirmation — received in writing from seller or management

Phase 4: Post-Closing First-Year Tasks

Closing is not the end of due diligence — it is the beginning of ownership. The first year after you close sets the conditions for everything that follows. Associations operate on annual budget and governance cycles, and the first cycle you participate in as an owner will reveal what the board knows is coming, what is being deferred, and what kind of governance culture you have joined.

Owner-onboarding documents from the association

Within a few weeks of closing, you should receive (or request) from the association:

• Welcome packet with contact information for management
• Parking and amenity access credentials
• Move-in procedures, building rules, and any form that documents your receipt of governing documents
• Registration information for the online owner portal, if one exists

Texas SB 711 (effective September 2025) requires associations with 60 or more units to maintain a website with their key governing documents. Florida HB 913 (2025) added an online-publication requirement for meeting minutes and governing documents for covered associations. If your association has not set up these systems, ask management directly for the documents you are entitled to.

Setting up dues payment and account access

Set up automatic payment for monthly dues before your first bill cycle. Late fees on association dues can escalate into formal notices, and in some states, short delinquencies can trigger the lien procedures — though reform legislation like Arizona's SB 1494 (2025) has raised the foreclosure threshold meaningfully. Even so, managing payment automatically removes the risk entirely.

Confirm in writing to management the unit address, your contact information, and your preferred communication method. Some associations manage records by owner name only; if your unit has had multiple recent owners, verify that the management company has your current information before the first dues cycle.

HO-6 insurance and loss-assessment coverage

Your individual condo owner's insurance policy — the HO-6 — needs to do three things well:

Cover the gap between the master policy and your unit. If the association carries bare-walls coverage, your HO-6 needs to cover all interior fixtures, finishes, and improvements. If the association carries all-in coverage, your HO-6 primarily covers your personal property and liability, with a smaller dwelling coverage need. Confirm the master policy coverage model before you bind your individual policy.

Cover your liability. Standard HO-6 policies include personal liability coverage. This matters not only for accidents in your unit but for any situation where an owner's unit is the origin of damage to a neighbor's unit — a broken pipe, a fire, an overflowing appliance.

Include loss-assessment coverage. This is the provision that pays your share of a special assessment up to the policy limit if the association levies an unexpected assessment — for a windstorm deductible gap, an uninsured structural repair, or another covered event. The standard loss-assessment coverage in many policies is $1,000. That is inadequate. In markets with significant storm exposure or older buildings with reserve shortfalls, carrying $50,000 to $100,000 of loss-assessment coverage is prudent. The premium increment for higher limits is typically modest.

Engaging with the board: meetings, committees, votes

The association's governance is co-ownership in practice. Board decisions on reserves, assessments, vendor contracts, and rule changes directly affect your financial exposure and living experience. Passive ownership leaves those decisions entirely to whoever is willing to serve on the board.

Attend the annual meeting. Review the proposed budget before it is adopted. If the association uses an online portal for owner communications, register and read it. If there is a budget hearing, attend or send written comment. If you identify governance concerns — persistent deferred maintenance, board members with apparent conflicts of interest, a reserve contribution that has not been updated to match the reserve study — these are appropriate matters to raise at meetings and, if needed, through formal owner channels.

A separate article on legal pitfalls for condo boards describes the specific governance failure patterns that tend to produce legal exposure and special assessments, and what they look like in meeting minutes.

Year-one signals to watch

In your first year as an owner, the following events are the ones that matter most for your financial planning:

Budget adoption. The annual budget cycle is when the board sets next year's dues. A dues increase of 5% to 10% in a well-run association is normal — insurance costs and labor costs are both rising. An increase above 10% typically reflects either a material change in operating costs (a large insurance premium increase, a new management contract) or a board that has been keeping dues artificially low and is beginning to correct. A dues increase accompanied by a special assessment in the same cycle is the signal that the board has run out of room to defer.

Reserve study update. Most reserve specialists recommend updating the study every three to five years, and Florida law mandates a SIRS update for covered buildings. If a reserve study update is on the board's agenda during your first year, attend or review the results. An updated study that reduces the percent-funded figure or increases the recommended annual contribution is telling you the board's prior funding plan was optimistic.

Special-assessment discussion. In the meeting minutes, pay attention to any agenda item that mentions pending repairs, engineering reports, insurance claims, or lender correspondence. These items often precede formal assessment votes by one to three board meeting cycles. An assessment that appears in the minutes as a discussion item in January and becomes a formal vote in March was foreseeable in January. Knowing the pattern means you are not surprised when the vote occurs.

Insurance renewal. The annual master policy renewal is when the association may face premium increases, coverage reductions, or — in stressed markets — non-renewal. A meaningful premium increase that the board does not address through the budget will eventually surface as a dues increase or assessment. A coverage gap that the board accepts at renewal may surface as a special assessment after the next weather event.

A Note on Professional Review

This checklist is a framework for the questions to ask, the documents to read, and the signals to recognize. It is not a substitute for professional review where the stakes warrant it.

A real estate attorney licensed in your state is the appropriate person to advise on the legal implications of specific document disclosures — pending litigation, contested assessments, structural findings, or unusual governing-document provisions. An attorney review of the declaration's unit-boundary definitions and the association's current legal exposure is typically worth the cost, particularly for older buildings or in states with active legislative change like Florida.

A qualified reserve specialist can provide an independent assessment of whether the association's reserve study and funding plan are realistic — particularly if you are buying in a building where the percent-funded figure is low or the reserve study is more than three years old.

CondoSignal's document review identifies the risk signals across the package — reserve funding gaps, budget-to-minutes inconsistencies, insurance coverage concerns, governance patterns — and presents them in a structured report with citations to the specific document pages where each finding appears.
