Why Your Condo Might Be Non-Warrantable (And What It Means for Your Sale Price)

A non-warrantable condo can't get conventional financing from Fannie Mae or Freddie Mac. That means fewer buyers, lower offers, and a longer time on market, all because of the building's finances, not your unit.

A condo becomes non-warrantable when it fails any one of the Warrantability Checklist: the six criteria Fannie Mae checks, covering reserves, delinquency, single-entity ownership, presale, insurance, and commercial space. Four of those six map directly to the GoverningDocs 5-Number HOA Health Check, which is why running the Health Check before you make an offer catches most warrantability problems early. The composite verdict shows up as the GoverningDocs HOA Health Grade on every property report.

What makes a condo non-warrantable?

A condo building can fail Fannie Mae's test for any one of these reasons, and when it does, no unit in it qualifies for a conventional loan, not just yours. Ask the lender or property manager about each: more than 15% of units are 60 or more days behind on dues (B4-2.2-01); the building budgets less than 10% of its yearly dues (assessment) income for reserves, rising to 15% for loan applications dated on or after January 4, 2027 (B4-2.2-01, LL-2026-03); one owner or company holds more than 20% of the units in a project of 21 or more units, or commercial space is more than 35% of the project (B4-2.1-03); a new project has sold fewer than 50% of its units (B4-2.2-02); or the master insurance policy falls short of Fannie Mae's coverage requirements.

Important update: the separate "50% investor concentration" rule was retired by Lender Letter LL-2026-03 effective March 18, 2026. Don't confuse it with the 20% single-entity rule, which still applies.

A widely shared r/RealEstate discussion captured this well: a New Jersey agent described a listing that sat for months because buyers couldn't get financing approved, not because of the unit, but because of the building's financials. An Atlanta condo owner in the same thread described their building's master insurance premium more than doubling, a ripple effect from Florida's insurance crisis that repriced risk in markets across the country.

These are anecdotal accounts, but they illustrate a pattern that real estate professionals are seeing more frequently. Most owners don't find out their condo is non-warrantable until a buyer's lender rejects the deal mid-contract.

What "Non-Warrantable" Actually Means

A condo is "warrantable" when Fannie Mae or Freddie Mac will back loans on it. Non-warrantable means they won't, and conventional lenders can't sell those loans on the secondary market.

When you buy a condo, your lender doesn't just evaluate you. They evaluate the entire building. Fannie Mae and Freddie Mac set eligibility criteria for condo projects (financial stability, insurance coverage, occupancy ratios) because they're the ones backing most conventional mortgages.

If the building fails those criteria, it's classified as non-warrantable. That means:

• No conventional mortgage financing (no 30-year fixed at market rates)
• Buyer pool shrinks to cash buyers and portfolio lenders
• Portfolio loans typically require higher down payments and charge higher interest rates
• Sale prices can drop significantly because fewer people can qualify to buy

If you're a seller, this hits your bottom line directly. If you're a buyer, it affects your ability to get a loan, and your future resale value.

How Buildings Get There: The Death Spiral

Non-warrantability rarely happens overnight. It usually follows a pattern: underfunded reserves lead to deferred maintenance, which drives insurance increases, which pushes delinquencies up, until the building crosses a lender threshold.

Here's the pattern playing out in buildings across the country:

New Jersey's reserve study legislation is an example of how external factors can surface pre-existing problems quickly. When reserve studies are completed or updated to comply with new state laws, the resulting reports may reveal funding levels that lenders flag during condo project review, creating selling challenges for owners whose buildings were never transparent about their reserve status.

The 6 Triggers Most Owners Miss

This is a different list from the six criteria Fannie Mae checks above. Those are the formal checklist; these are the six problems that most often catch owners off guard. This list adds litigation and state rules, and leaves out presale and commercial space, which mostly matter for new or mixed-use buildings. Fannie Mae's condo project eligibility rules cover reserve funding, delinquency rates, material litigation, insurance, and single-entity ownership. Some lenders also ask about state-specific structural compliance. Any one can disqualify a building.

• Budgeted reserves under 10% of annual budgeted assessment income. Per the Fannie Mae Selling Guide (B4-2.2-01), the lender divides the annual budgeted replacement reserve allocation by the association's annual budgeted assessment income, and the result must be at least 10%. Fannie Mae's Lender Letter LL-2026-03 raises that to 15% for loan applications dated on or after January 4, 2027. Note the denominator: it is assessment income, not the operating budget and not total expenses. Certain income may be deducted before the ratio is run, including incidental income the association does not rely on, income collected for utilities that unit owners would normally pay themselves, income allocated to reserve accounts, and special assessment income. A current reserve study can also substitute for the percentage test, so a building under 10% is not automatically ineligible. This is different from percent funded : a building can be 70% funded but still fail if its annual budget doesn't allocate enough going forward.
• More than 15% of units 60+ days delinquent on assessments. Per the Fannie Mae Selling Guide, this threshold triggers financing denial. One bad year of collections can flip a building.
• Material litigation against the HOA. Not every lawsuit disqualifies a project. Routine liability claims covered by the HOA's insurance generally don't. What lenders flag is material litigation: construction defect claims, disputes that could result in large financial judgments, or cases that could materially affect the HOA's financial stability. Your lender will evaluate the nature and scope of any pending litigation.
• Insurance coverage gaps or non-renewal. If the master policy doesn't meet Fannie Mae's coverage minimums, the building fails. Premium spikes that cause coverage reductions are equally disqualifying.
• Single entity owns more than 20% of units. High investor concentration signals rental-heavy buildings. This is a common issue in newer developments.
• State-specific compliance failures. Fannie Mae does not list these as their own trigger, but some lenders now ask whether a Florida building has completed its structural integrity reserve study (SIRS) or a California building its SB 326 balcony inspection. Ask your lender whether it checks.

How to Check Your Building Before It's Too Late

Request the reserve study for percent funded, ask management for the delinquency rate, review the insurance certificate for coverage gaps, and check recent board minutes for litigation mentions.

You don't need a lender to tell you there's a problem. These four steps can flag issues before they kill a deal:

1. Get the reserve study. Find the percent funded number and the annual budget allocation to reserves. You're looking for both: overall funding level AND the annual contribution rate. Upload your reserve study to GoverningDocs for a free analysis that pulls these numbers automatically.

2. Ask management for the delinquency rate. A simple question: "What percentage of units are 60 or more days past due on dues?" Above 15% is a problem. Most management companies can pull this number from their software in minutes.

3. Review the insurance certificate. Ask for the master policy certificate and check the coverage amount, premium trend over the past 2–3 years, and renewal status. A premium that doubled in two years is worth investigating further.

4. Read recent board minutes. Three to five years of meeting minutes will surface litigation mentions, deferred maintenance discussions, and emergency assessments. See our guide on red flags in HOA meeting minutes.

If Your Building Is Already Non-Warrantable

Non-warrantability isn't permanent. Fix the failing criteria ( reserve funding, delinquency, litigation) and the building can regain eligibility. But it takes board action and time.

Your options depend on which trigger caused the problem:

• Reserve funding issue: The path back typically involves updating the reserve study, adopting a funding plan that meets the 10% budget allocation threshold (15% for loan applications dated on or after January 4, 2027), and demonstrating that plan to lenders. A reserve study professional can document the current status and a credible path to compliance. This takes at minimum a full budget cycle to demonstrate to lenders.
• Delinquency issue: Collections enforcement is the lever here. This takes time and often requires working with HOA counsel on the collection process. It's harder to fix quickly than a reserve funding gap.
• Litigation: If the material litigation settles or is dismissed, lenders can reassess the project's eligibility. Until it's resolved, the uncertainty is what creates the problem for buyers seeking conventional financing.
• If you're selling now: Many real estate professionals recommend getting a lender warrantability check done before listing so pricing reflects the actual buyer pool. Consult a real estate agent or attorney familiar with your state's disclosure requirements: what needs to be disclosed and when varies by location.
