Quick Answer & Key Finding

An FHA loan is a government-backed mortgage insured by the Federal Housing Administration, allowing qualified borrowers to buy a home with a 3.5% down payment and credit scores as low as 580. In exchange for low down payment barriers, FHA borrowers must pay an Upfront Mortgage Insurance Premium (UFMIP) equal to 1.75% of the base loan amount, plus an annual Monthly Mortgage Insurance Premium (0.50% to 0.55%) that typically lasts for the entire 30-year term.

1. FHA Two-Tier Insurance Structure FHA insurance protects mortgage lenders against foreclosure loss through two sequential fees: 1. **Upfront MIP**: Exactly 1.75% of the base loan amount, almost always added to the principal balance. 2. **Annual MIP**: Divided by 12 and added to every monthly mortgage check: $$\mathbf{\text{Monthly MIP}} = \frac{\text{Base Loan Balance} \times 0.55\%}{12}$$

Frequently Asked Questions

Can you remove FHA MIP without refinancing?
If you put down less than 10%, FHA MIP remains for the entire life of the loan. The only way to remove it is by refinancing into a conventional mortgage once you reach 20% equity.
What is the maximum debt-to-income (DTI) ratio for an FHA loan?
Standard FHA guidelines look for front-end DTI of 31% and back-end DTI of 43%, but automated underwriting systems (AUS) regularly approve borrowers up to 45% to 50% with compensating factors.
