Mixed-Use Property Financing in Tennessee

How lenders define mixed-use

A mixed-use property has both residential and commercial components — typically a storefront or office on the ground floor with residential units above. Common examples include a retail shop with an apartment above, a live-work loft, or a building with a restaurant on the ground floor and condos on upper floors.

The key question for residential financing is the percentage of the property's value and income that comes from commercial vs. residential use.

Residential mortgage limits on commercial space

Fannie Mae and Freddie Mac allow residential financing for mixed-use properties under specific conditions:

• The property must be primarily residential in character
• The commercial space must not exceed 35% of the total gross building area
• The commercial use must be legal and conforming under local zoning
• The residential portion must be self-contained (separate entrance, utilities)

FHA has similar restrictions. Properties where commercial space exceeds these thresholds, or where the commercial use is the dominant income source, will not qualify for standard residential financing.

Portfolio and commercial financing for mixed-use

Mixed-use properties that don't meet residential guidelines require portfolio lending or commercial real estate financing. Portfolio lenders hold loans on their own books rather than selling to Fannie/Freddie, giving them flexibility to underwrite non-standard properties.

Commercial real estate loans for mixed-use properties are typically shorter-term (5–10 year balloon), require 25–30% down, and are underwritten based on the property's net operating income rather than the borrower's personal income.
