House hacking—purchasing a multi-family property, living in one unit, and renting out the remaining units—is one of the fastest paths to wealth creation. For owner-occupants, the primary financing decision comes down to FHA vs. Conventional loans.
While FHA allows a lower 3.5% down payment, conventional loans (now permitting 5% down on 2-4 units) offer significant advantages in mortgage insurance cancellation and bypass the rigorous FHA Self-Sufficiency Test.
Down payment and loan limit comparisons
FHA financing allows 3.5% down across 2-, 3-, and 4-unit residential properties with minimum credit scores of 580. Loan limits are scaled higher for multi-unit properties, providing substantial purchasing power.
Fannie Mae and Freddie Mac guidelines permit 5% down payments on primary residence 2-4 unit properties, eliminating the previous requirement for 15% to 25% down payments on multi-unit conventional loans.
Mortgage insurance: lifetime MIP vs. cancellable PMI
FHA loans charge an upfront mortgage insurance premium (UFMIP of 1.75%) plus an annual Mortgage Insurance Premium (MIP) that remains for the entire life of the loan when putting less than 10% down.
Conventional loans feature Private Mortgage Insurance (PMI) that can be automatically cancelled once the loan balance reaches 78% of the original property value, or removed earlier through appraisal appreciation.
The 3-4 unit self-sufficiency hurdle
For 3- and 4-unit properties, FHA requires 75% of total market rents to exceed the full PITIA monthly payment. In expensive real estate markets with high property taxes, many 3-4 unit properties fail this test.
Conventional financing does not apply a self-sufficiency test, making conventional 5% down loans the go-to solution for 3- and 4-unit buyers in competitive, higher-priced metropolitan areas.
Decision matrix for multi-unit buyers
Evaluate your credit profile, property unit count, and holding strategy to choose the right loan product.
- Choose Conventional 5% Down if purchasing a 3-4 unit property that cannot pass FHA self-sufficiency.
- Choose Conventional 5% Down if you want the ability to eliminate monthly PMI once equity reaches 20%.
- Choose FHA 3.5% Down if your credit score is below 680 or your debt-to-income ratio exceeds 45%.
- Verify that all units have separate electrical meters and safe, legal ingress/egress.
