HOA Special Assessments and Reserve Studies: The Condo Risk Check Before You Buy
Low condo dues can hide a big bill. Here is how to read an association's reserves, reserve study and minutes, and why the building's financing status matters when you sell.

State condo laws differ; Florida, for example, now requires structural inspections and reserve studies for many older buildings. The worked example is illustrative. This is general information, not legal advice. How we check numbers →
Before buying a condo, check the association's reserves, its latest reserve study, meeting minutes and any planned special assessments. Underfunded buildings pass big repair bills to owners, often thousands per unit. Lenders care too: Fannie Mae generally wants at least 10% of the budget going to reserves and won't finance units in buildings needing critical repairs, which can make a unit hard to sell.
Numbers That Matter
| Rule | What it says | Source | Verified |
|---|---|---|---|
| Reserve funding for conventional loans | The budget generally must fund replacement reserves of at least 10%, unless a qualifying reserve study supports less | Fannie Mae Selling Guide B4-2.2-02 | Sep 28, 2026 |
| Special assessment delinquencies | No more than 15% of units 60+ days behind on a special assessment | Fannie Mae Selling Guide B4-2.2-02 | Sep 28, 2026 |
| Buildings needing critical repairs | Ineligible for Fannie Mae financing until repairs are done | Fannie Mae Selling Guide B4-2.1-03 | Sep 28, 2026 |

Reserves, Reserve Studies and Special Assessments
- Reserves are the association's savings for big, predictable replacements: roofs, elevators, paving, balconies.
- A reserve study estimates when each component needs replacing, what it will cost and how much the association should be saving; "percent funded" compares actual savings with that target.
- A special assessment is a one-time or temporary charge to owners when reserves fall short, sometimes tens of thousands of dollars per unit.
The Condo Risk Check
- Budget and reserves: what share goes to reserves, and how much is saved.
- The latest reserve study: its date, the percent funded and big items due soon.
- Special assessments: current, planned and discussed; ask who pays one approved before closing.
- Meeting minutes from the last one to two years, for repairs, disputes and lawsuits.
- The master insurance policy: coverage, deductible and recent premium jumps.
- Delinquencies and financing status: how many owners are behind, and whether the building qualifies for conventional, FHA or VA loans.
Why It Matters for Resale
If a building doesn't meet lender standards, most buyers can't get a conventional or FHA loan for a unit there, which narrows your future buyers to cash purchasers and can pull prices down. Since the 2021 building collapse in Surfside, Florida, lenders and regulators have looked harder at deferred maintenance and reserve funding, and some states have added inspection and reserve requirements.
Worked Example: A Repair Bill Reserves Can't Cover
- The gap: roof and balcony repairs cost $2,000,000; reserves hold $500,000, leaving $1,500,000.
- Per owner: split equally, that's $15,000 per unit.
- Spread out: paid over 24 months, it adds $625 a month on top of regular dues.
Many associations allocate costs by each unit's ownership share rather than equally.
Decision Rules
If this, then that
- If reserves are thin and big items are due → budget for a special assessment or negotiate the price.
- If a special assessment is pending → make who pays it part of the contract.
- If the building isn't approved for common loan types → expect a harder resale.
- If the master policy's deductible is high → check whether your unit policy covers loss assessments.
- If the documents are incomplete → make your offer contingent on reviewing them.
Mistakes to avoid
- Judging a condo by low monthly dues alone.
- Skipping the reserve study and meeting minutes.
- Assuming a pending assessment is the seller's problem.
- Ignoring the building's financing status.
- Forgetting loss-assessment coverage on your own policy.
