Illinois condo financing requirements
Financing an Illinois condo turns less on state mandates than on the association's reserves, insurance, and physical condition. Illinois requires only "reasonable reserves" for post-1990 condo budgets with no fixed funding percentage, mandates no formal reserve study, and runs no statewide structural-inspection program — so lenders and the secondary market apply their own warrantability rules: reserve contributions (the GSEs commonly look for a budget line of at least 10% to reserves), master-insurance adequacy, deferred maintenance, pending special assessments, and litigation.

Because Illinois condos can legally run thin or even waived reserves, an Illinois unit can be perfectly financeable on your own numbers yet ineligible because of the building's reserves, insurance, or active litigation.
Reserves: a 'reasonable' standard with no funding floor
Illinois condo budgets adopted after July 1, 1990 must provide for "reasonable reserves" for capital expenditures and deferred maintenance under Section 18, but the statute sets no required percentage, no schedule, and no mandatory reserve study — and owners can formally waive reserve contributions by a two-thirds vote, which must be disclosed conspicuously. Lenders and the GSEs scrutinize this directly: conventional underwriting commonly expects the budget to allocate at least 10% to reserves (or a project-specific reserve study showing adequacy), so a thin or waived Illinois reserve line that is perfectly legal under state law can still make a project non-warrantable. Read the disclosed reserve status, the capital-expenditure schedule, and any reserve study together, and treat a formal reserve waiver as both a financing and a special-assessment risk.
Master insurance and the GSE deductible standard
Conventional financing requires the master policy to meet GSE standards: Illinois condos must carry property coverage at full replacement cost and at least $1M liability under 765 ILCS 605/12, which aligns with warrantability, but the per-unit master property deductible is generally capped by the GSEs at 5% of coverage. Illinois does not cap deductibles, and with homeowner premiums up roughly 13% in 2023 and hail-driven losses, boards have been raising wind/hail deductibles — so a master deductible above the 5% threshold, or a policy that excludes wind/hail, can complicate a Fannie Mae or Freddie Mac loan. Pull the declarations page early and check the deductible and coverage basis before assuming the loan is clean.
Special assessments, litigation, and warrantability
A levied or approved special assessment affects both warrantability and your debt-to-income calculation, and active litigation can make a project non-warrantable because lenders disfavor associations in litigation. Illinois's common claim categories include construction-defect actions against developers and builders (with a statute of repose tolled until the first unit-owner board election under 765 ILCS 605/18.1), insurance-coverage disputes (water intrusion, mold), and assessment collections. The resale certificate must list pending litigation, but read it together with two to three years of minutes and a directly requested full litigation summary to gauge financing friction. Remember the six-month rule (765 ILCS 605/9(g)(4)): a foreclosure buyer can owe up to six months of back dues, a factor in distressed-unit financing.
If the project is non-warrantable
A non-warrantable Illinois condo pushes buyers toward portfolio, FHA, or VA lenders at higher rates or lower leverage, and it shrinks your future resale pool — the next buyer faces the same constraint. This risk concentrates in older Chicago high-rises and conversions with aging mechanicals, thin reserves, or pending façade work, and in smaller suburban associations with modest budgets and deferred maintenance. Confirm the project's warrantability status with your lender early, price portfolio alternatives if needed, and build a financing and document-review contingency into the contract so a reserve, insurance, or litigation issue surfacing in underwriting does not derail the closing.

- Check whether owners formally waived reserve contributions (2/3 vote, must be disclosed)
- Pull the master-policy declarations page and check the deductible against the GSE 5% cap
- Confirm the master policy shows full replacement cost and at least $1M liability (765 ILCS 605/12)
- Identify any levied or approved special assessment affecting warrantability and DTI
- Request a full pending-litigation summary — active litigation can make a project non-warrantable
- If non-warrantable, price portfolio / FHA / VA terms and weigh the resale impact

The risk lives in the contradiction between documents.
