Your estimate factors in your household income, any existing monthly debt, and credit score, then layers in the home price, down payment, interest rate, and loan term you enter to work out a monthly mortgage payment - weighed against your income to gauge how risky the purchase would be.
These key factors affect home affordability
Income and expenses
Your income sets the ceiling on what's realistically affordable, but existing debt narrows that further. Every debt you've logged gets weighed alongside your income before we factor in a new mortgage payment, since a lender would do the same.
Credit score
A higher credit score typically qualifies you for a lower interest rate, which lowers your monthly payment and effectively raises how much home you can afford. A lower score usually means worse loan terms in practice even at the same purchase price, which is why it nudges your risk score up here too.
Debt-to-income ratio
Lenders generally want your housing costs under 28% of your income, and your total debt - including that housing payment - under 36%. Our risk levels are built around similar thresholds, so a "low risk" result roughly tracks what a lender would consider comfortably affordable.
Down payment
A larger down payment shrinks your loan amount, which lowers your monthly payment two ways: less principal to pay off, and often a better interest rate. Conventional loans can go as low as 3% down, FHA loans 3.5%, and VA or USDA loans as low as 0% for eligible buyers - but more down upfront generally means more breathing room every month after.
Interest rate and loan term
A longer term (30 years vs. 15) lowers your monthly payment but costs more in total interest over the life of the loan. Interest rate has an outsized effect on affordability - even a single percentage point can shift a typical mortgage payment by hundreds of dollars a month.
Property taxes, insurance, and HOA fees
Beyond principal and interest, ongoing costs like property taxes, homeowners insurance, and (if applicable) HOA dues add up every month. These vary a lot by location, so it's worth padding your estimate if you're house-hunting somewhere with higher taxes or mandatory association dues.
How to use your results
Your risk score reflects the mortgage payment at the price, down payment, rate, and term you entered. Try adjusting each one to see how it moves the needle:
- Down payment - see how putting more down lowers your monthly payment and risk score.
- Loan term - compare a 15-year term's higher payment against a 30-year term's lower one.
- Interest rate - model what a slightly better (or worse) rate does, since actual quotes vary by lender and credit profile.
- Existing debt - add any car payments, student loans, or credit cards you're carrying for a more realistic number before you go house-hunting.
Ways to increase how much house you can afford
- Pay down existing debt to improve your debt-to-income ratio before applying for a mortgage.
- Work on your credit score - even a modest improvement can unlock a meaningfully better rate.
- Save for a larger down payment to borrow less and potentially avoid PMI.
- Add a second income source if you have one - joint applications are evaluated together.
- Consider a longer loan term to lower the monthly payment, understanding it costs more in total interest.
