Estimate monthly payment shape on a $300K FHA-style purchase before you request lender quotes

FHA Payment on a $300K House With 3.5% Down: Scenario

This page walks through a $300,000 purchase with a 3.5% down payment in an FHA-style framing. It breaks out principal, interest, taxes, insurance, and modeled mortgage insurance so you can discuss numbers confidently with lenders. Assumptions are illustrative only and not an offer to lend.

Scenario profile: $82,000 annual income ($6,833/month gross), $520 monthly non-housing debt, 640 credit score, 3.5% down on $300,000, 30-year term.

Affordability analysis

On a $300,000 price, 3.5% down implies roughly $289,500 financed before closing costs—not the same as cash to close. Mortgage insurance in FHA-style structures can be a meaningful share of monthly cost, so compare all-in payment, not rate alone.

DTI discussion

At $6,833 gross monthly income, housing payment plus $520 debt defines your back-end DTI. If that sum drifts above common planning bands, consider a lower price, higher down payment, or debt reduction before application. Estimated back-end DTI in this scenario is 42.6% (Moderate).

Estimated back-end DTI in this scenario: 42.6%

Potential strengths

3.5% down can preserve liquidity for reserves.
Structured payment example clarifies what to ask lenders.

Potential constraints

MIP can materially affect monthly cost.
Tax and insurance variance by location can change the picture.

What may improve qualification

FHA is often part of the conversation at this down payment level, but you should still ask lenders how overlays and reserves affect your file. FHA may be the stronger baseline while improving profile for conventional pricing.
