HouseholdMath Turns a House Price into a Household Burden

Field notes

Users can substitute a state or ZIP code for a full street address, then adjust loan type, term, down payment, interest rate, property type, HOA fee, and refinance details. The page separates mortgage insurance from the rest of the payment and runs lender income ratios backward from total housing cost. Its examples include a 2019 Chicago purchase where property tax is described as nearly a third of principal and interest, and a 2011 Oakland purchase affected by California's two-percent assessment cap.
