House affordability by income

Reference tables for 26 incomes from $40,000 to $1,000,000 a year. Each page turns the common 28% housing guideline into a home price at rates from 6% to 7%, with 10% or 20% down, and states every assumption behind the figure so it can be challenged.

Companion references: the mortgage payment tables and the free rent vs buy calculator.

Every figure assumes housing capped at 28% of gross income, a 30-year fixed loan, 1.1% annual property tax, and $1,500 annual insurance; other debts and mortgage insurance lower the result. Rates shown are a reference range, not current quotes. By Devon Coombs, CPA, MBA, Teaching Professor of Finance at Santa Clara University.
