Non-Warrantable Condo Financing

Updated 20 May 2026

Roughly 15% to 25% of US condos do not meet Fannie Mae or Freddie Mac guidelines for conventional financing. These "non-warrantable" buildings still trade, but at higher rates, larger down payments, and through a smaller universe of portfolio lenders. This page covers what makes a condo non-warrantable, who lends, what the rate premium looks like, and when buying a non-warrantable unit makes financial sense despite the friction.

The 8 most common non-warrantable triggers

Trigger	Rule basis
More than 50% units investor-owned	Fannie/Freddie owner-occupancy threshold
Single entity owns more than 10% of units	Concentration risk per GSE rules
Pending material litigation against HOA	Potential liability exposure
Inadequate reserve funding	Less than 10% of annual budget to reserves
Commercial space exceeds 25% to 35%	Mixed-use ratio limit (varies by GSE)
Hotel-like operations (condotel)	Daily-rental amenities, front desk, room service
New construction with developer control	Pre-stabilisation buildings often non-warrantable until 51% sold
Master insurance below required limits	Replacement cost coverage below GSE thresholds

Portfolio lender economics

Portfolio lenders (banks and credit unions that hold loans on their own balance sheet rather than selling to Fannie/Freddie) are the main source of non-warrantable financing. They underwrite to internal rather than agency standards. Typical terms for non-warrantable condos in 2026:

Down payment: 25% to 40% (vs 3% to 20% for warrantable conventional)
Rate premium: 0.75% to 2.0% above prevailing conventional rate
Reserves required: 6 to 12 months of full PITI plus HOA in liquid post-closing
DTI cap: typically 43% back-end, sometimes lower
Loan-to-value: capped at 60% to 75%
Adjustable-rate often required: 5/1 or 7/1 ARMs more common than 30-year fixed

Lenders specialising in non-warrantable in 2026 include several regional banks, jumbo-focused mortgage banks, and condo-specialist credit unions. Mortgage brokers can often access multiple portfolio lenders to compare; direct shopping is harder.

When buying a non-warrantable condo makes sense

The unit is priced 10% to 20% below comparable warrantable inventory (which it often is, because of the buyer pool restriction).
You can afford 30%-plus down and the higher rate without stress.
The cause of non-warrantability is fixable in 12 to 36 months (sponsor sell-through, litigation resolution), creating future refi-to-conventional opportunity.
You see clear long-term value in the building (location, character, walkability) that the warrantable-only buyer pool is missing.
