How Much House Can I Afford in Oklahoma?

How the calculator decides

Lenders compare two ratios with your gross monthly income: the housing ratio (the full house payment) and the total debt-to-income ratio (house payment plus your other monthly debts). The calculator takes the smaller of the two payment limits, then searches for the highest price whose full payment (principal and interest, property tax, insurance, PMI or FHA MIP, and HOA dues) fits under it. Because tax, insurance and mortgage insurance all rise with the price, it solves numerically rather than working backward from a single formula.

Which debt-to-income limits to use

28/36 (28% of income for housing, 36% for all debts) is a common rule of thumb, not a lender rule, and it's the default. The 31/43 option uses the FHA manual-underwriting caps in OHFA's February 2026 lender training. Loans approved through automated underwriting can go higher: the same training lists a 45% maximum debt-to-income for FHA borrowers with 640–679 credit scores and up to 50% at 680 and above. A higher ratio means a bigger payment relative to income, not necessarily a comfortable one.

Why Oklahoma's numbers lower the answer

Insurance takes a bigger share of the payment in Oklahoma than anywhere else: the statewide average is $5,298 a year (LendingTree, 2026). By default the calculator scales that average with the price ($5,298 for a $350,000 dwelling), which is a rough assumption you can replace with a quote.

Example: $85,000 household income, $400 a month of other debts, $20,000 down, a conventional loan at 7.40% (Freddie Mac, week of Oct 8, 2026), in Oklahoma City (district code 200, homestead exemption). At 28/36 the highest price is about $218,313, with a payment of $1,983.33. Leave insurance out entirely and the same income would stretch to $250,521, so leaving insurance out overstates the budget by $32,208. At the FHA manual caps (31/43) it's $239,971.

Program and loan limits to keep in mind

• OHFA GOLD: $349,525 maximum price ($427,198 in targeted areas), plus county income limits.
• OHFA DREAM: $356,362 with a government loan, $453,100 conventional.
• FHA: $541,287 maximum one-unit base loan in every Oklahoma county (2026).
• Conforming: $832,750 one-unit limit in every Oklahoma county (2026).

The results panel flags any of these your maximum price crosses. To check the OHFA income limits for your county and household, use the OHFA eligibility check.

What's not included

The down payment you enter is only the down payment. Closing costs, prepaid interest and escrow deposits come on top; the closing cost calculator adds them up. Credit score, cash reserves and the lender's other rules aren't modeled.

The formula

Housing limit = min(F × I ÷ 12, B × I ÷ 12 − D)
Max price = highest P with Payment(P) ≤ Housing limit
Payment(P) = M(P − down) + tax(P)/12 + insurance(P)/12 + PMI or MIP + HOA
