Why Miami Condo Deals Fall Apart — and How to Check the Building First

Here's something that surprises buyers moving to Miami from anywhere else: your loan can be perfect and your deal can still collapse. In condo purchases, the lender underwrites two borrowers — you and the building. And in Miami, where the majority of urban inventory is condo and much of the stock is older, the building is the one that fails.

What "warrantable" actually means

A warrantable condo meets the project standards that Fannie Mae and Freddie Mac set — the criteria that make a building eligible for conventional financing. A building is generally reviewed on things like its budget and reserve funding, how much of it is renter-occupied versus owner-occupied, whether one entity owns an outsized share of units, how much commercial space it contains, whether the developer still controls the association, and whether there's litigation.

Fail one of those tests and the building becomes non-warrantable. That word has a bad reputation it doesn't fully deserve. Non-warrantable doesn't mean the building is falling down or that the purchase is a mistake — it means conventional financing isn't available, and you need a different program. In Miami, non-warrantable is not an exception. Investor-heavy towers, mixed-use buildings with ground-floor retail, brand-new projects still in presale, and buildings with active litigation are simply everywhere.

The post-Surfside reality every Miami buyer should understand

After the Champlain Towers South collapse, Florida enacted structural milestone inspection requirements and stricter reserve-funding rules for condo associations. The intent was safety, and it was necessary. The financial consequence rippled through the entire market: associations that had underfunded reserves for years had to confront real numbers, and that arrived as higher monthly dues and, in many buildings, substantial special assessments.

For a buyer, this hits in two directions at once. Higher dues increase your qualifying payment, which directly reduces how much home you can afford. And a building carrying a large assessment or an unresolved inspection finding can face financing problems of its own. Both of these live in documents — the budget, the reserve study, the meeting minutes — that most buyers never read until they're already committed.

How to check a building before you fall in love

This is the entire point of the article. The check takes a day or two, and it happens before you write an offer, not after:

1. Send the address to your lender first. Not the unit — the building. Many buildings have known histories, and an experienced local lender can often tell you the likely financing path immediately.
2. Get the budget and reserve information. How much is in reserves, and how does it compare to the building's obligations? Underfunded reserves are the leading indicator of a future assessment.
3. Ask about litigation directly. Not all litigation is disqualifying — routine, non-structural matters are often fine — but structural claims or major disputes change what's financeable.
4. Ask about the milestone inspection status. Has it been done? What did it find? Is there a funded plan to address the findings?
5. Ask about special assessments — past, current, and proposed. "Proposed" is the one buyers forget. An assessment being discussed at the last board meeting will still be your problem after closing.
6. Check the renter ratio and commercial space. These drive warrantability directly, and neither is visible from the listing.

If the building is non-warrantable, you still have options

This is where a lot of buyers give up unnecessarily. Dedicated non-QM condo programs are built for exactly these buildings and accept conditions that conventional financing won't — litigation, heavy investor concentration, substantial commercial space, developer control, and new projects without agency approval. Under current guidelines that generally means around 20% down for a primary residence, with reduced leverage for investment purchases.

Buying the condo as a rental instead? DSCR financing covers condos too, qualifying on the property's rent rather than your personal income, including in non-warrantable buildings at lower leverage.

The one habit that saves Miami condo deals

Send the building before you send the contract. That's it. Everything expensive that happens in Miami condo transactions — lost deposits, failed financing two weeks before closing, discovering a $40,000 assessment after you own the unit — traces back to someone finding out about the building too late.
