Warrantable vs Non-Warrantable Condos: A Miami Financing Guide

In Miami, whether you can get a mortgage often depends less on your finances and more on the building. Here's the distinction that trips up more Miami buyers than any other.

What "warrantable" means

A warrantable condo is a project that meets Fannie Mae / Freddie Mac (or FHA/VA) eligibility rules, so it qualifies for conventional conforming loans — better rates and down payments as low as ~10%. A non-warrantable condo fails one or more of those project rules, so conventional lenders won't touch it.

Crucially, this is a judgment about the whole building, not you. You can have an 800 credit score and still be denied because the project doesn't qualify.

Why so many Miami buildings are non-warrantable

Common disqualifiers — and Miami has a lot of them:

• Condo-hotel / condotel operation, or daily/short-term (Airbnb-style) rentals allowed.
• High investor concentration — a single entity owns more than ~25% of units, or too few are owner-occupied.
• Pending or active litigation (beyond minor matters).
• Inadequate reserves or master insurance — a bigger issue post-Surfside.
• Too much commercial space or an incomplete/newly built project with unsold inventory.

Post-Surfside, Fannie and Freddie added structural-safety and reserve screens, so an entire building can become effectively unfinanceable conventionally regardless of the borrower.

How to finance a non-warrantable condo

• Portfolio / non-QM loans — the lender keeps the loan on its own balance sheet instead of selling it to Fannie/Freddie, so it can set its own project rules.
• Expect higher down payments (often 20–35%+) and somewhat higher rates.
• Local banks, credit unions, and specialty lenders active in Miami do these routinely.
• Or pay cash — a large share of Miami condo sales do, then finance later via a cash-out refi if the building becomes warrantable.

Do this before you fall in love with a unit

Ask your lender to check the project's eligibility early — many will pull a condo questionnaire and reserve/insurance data on the building. It's heartbreaking to go under contract and learn at underwriting that no conventional lender will finance it.

The bottom line

In Miami, finance the building first and the unit second. If a condo allows short-term rentals or operates like a hotel, assume it's non-warrantable and line up a portfolio lender (and a bigger down payment) up front.
