How home affordability is estimated

Educational guide · Updated · About 7 min read

Affordability tools reverse the usual mortgage payment question: instead of “what is my payment on this price?”, they ask “what price fits a payment budget built from income?”

Three building blocks

  1. Gross income and other monthly debts you enter
  2. Sample front-end and back-end DTI caps (editable teaching percentages)
  3. Rate, term, down payment %, and optional tax/insurance/HOA

Sample

$80,000 income · 20% down · 6.5% · 30 years → about $280,165 (P&I about $1,416.67). Open sample
