Mortgage Calculator
The right amount of house is one you can pay off fast without becoming house-poor. This tool builds around one rule: a 15-year fixed mortgage with a payment no more than 25% of your monthly take-home pay.
Your actual after-tax pay that hits your bank account each month.
A 20% down payment lets you skip PMI. More down means more house within the rule.
15-year fixed rates are typically lower than 30-year rates. Use a quote from your lender.
The national average is around 1.1% of home value per year.

Why 15 Years and 25%?
A 15-year fixed-rate mortgage costs you far less in total interest than a 30-year loan and forces the discipline of paying the home off in half the time. Keeping the payment — including taxes and insurance — at or below 25% of your monthly take-home pay is what keeps you from becoming "house-poor," where the mortgage eats every dollar and leaves nothing for investing, giving, or living.
This calculator solves for the most expensive home whose full monthly payment (principal, interest, property tax, home insurance, and any HOA dues) lands at 25% of the take-home pay you entered. Lower your price below that number and you buy yourself even more breathing room. These figures are estimates for planning only — your lender's quote is the real number.
Consider Manual Underwriting
If you have little or no credit score because you've avoided debt, most automated systems will turn you away — not because you can't pay, but because you don't fit the algorithm. Manual underwriting is a process where a real underwriter reviews your actual history: your rent payments, utility payments, income stability, and savings. It rewards responsible behavior instead of penalizing you for not carrying debt.
Lenders like Churchill Mortgage specialize in manual underwriting for exactly this kind of borrower, and other banks and credit unions offer it as well. If a lender tells you that you "need" a credit score to buy a home, that's a signal to ask specifically about manual underwriting — or find one who does it.
