About House Affordability Calculator
Lenders size a mortgage from debt-to-income ratios, and this affordability calculator applies the same test to your annual income, existing monthly debts, down payment, rate and term. It returns a maximum home price and payment at the DTI limit you set, plus conservative, moderate and stretch prices at the 28, 36 and 43 percent thresholds. The monthly breakdown splits principal and interest from property tax, homeowners insurance and PMI, which it adds automatically when the down payment is under 20 percent. Nothing is sent to a server.
