The call usually comes in week three. The contract is signed, the inspection is paid for, the buyer is emotionally moved in — and the lender announces the building “didn’t pass project review.” Deal dead, deposits at risk, everyone scrambling.
I’ve been originating in South Florida since 2002, and I can tell you the honest part: that outcome was knowable before the offer was written. Here’s how condo warrantability actually works, and every path that still gets a non-warrantable building financed.
What “non-warrantable” actually means
Fannie Mae and Freddie Mac — the agencies behind most conventional mortgages — only buy loans in condo projects that pass their eligibility rules. A building that passes is warrantable: you can shop the entire conventional market at its best pricing. A building that fails any single test is non-warrantable, and conventional lenders step away no matter how strong you are as a borrower.
The building gets underwritten before you do. The common failure points:
- Pending litigation against the association — what kind of suit, against whom, and for how much all matter
- Inadequate reserves — the budget must set aside enough for future repairs
- Too many investors — owner-occupancy ratios below the line
- Single-entity concentration — one owner or company holding too many units
- Insurance gaps — wind, flood, or fidelity coverage that doesn’t meet guidelines
- Commercial space over the allowed share, or a project still under developer control
Why this bites harder in Florida than anywhere else
After the Surfside collapse, the agencies tightened project review sharply — reserves, deferred maintenance, and structural inspection items now carry real weight. Layer that on top of Florida’s insurance market, aging coastal buildings, and the special assessments hitting associations across Broward and Palm Beach, and you get a state where buildings that financed cleanly three years ago fail review today.
This isn’t rare. It’s a routine feature of the South Florida market, and it’s exactly why I check the building at the scenario stage — association questionnaire, budget, litigation picture — before my clients write an offer, not after they’ve paid for an appraisal.
The financing paths that still work
A non-warrantable label is a detour, not a dead end. Buildings that fail agency review get financed every day through these routes:
Portfolio and non-QM lenders. Lenders who keep loans on their own books write their own project rules. Expect a somewhat larger down payment — often 20–25% — and a rate premium for the flexibility. This is the standard path, and because every portfolio lender draws its lines differently, the same building can be a decline at one shop and a clean approval at another. Shopping the file is the whole game.
Limited-review options. Some conventional loans with larger down payments qualify for a lighter project review that certain buildings can pass even when a full review would fail. Whether your file fits is a structuring question — this is where an originator who knows the guidelines earns their keep.
Cash now, refinance later. Some buyers close in cash and refinance once the building’s issue resolves — litigation settles, reserves rebuild. It’s not for everyone, but for the right buyer it turns a “no” into a timing decision.
If the building operates like a hotel — front desk, rental program, nightly stays — that’s a condotel, its own category with its own small lender pool. I cover that world on my condo and non-warrantable condo loans page.
The move that saves the deal: check first
Every painful non-warrantable story I’ve seen shares one feature: nobody checked the building until underwriting did. The fix costs nothing. Before you write the offer — or the moment you’re under contract — have your originator pull the condo questionnaire and map the building against current guidelines.
When I run a condo file, that check happens first. Warrantable buildings go conventional at full market pricing. Non-warrantable buildings go straight to the right portfolio lender with the issue disclosed and priced from day one. Either way, you know what you’re buying before you’re emotionally — and financially — committed.
Buying the unit as an investment? The building review runs alongside the rent math; see how DSCR loans for Florida investment properties underwrite the property on its own income.
