About HomeMath

HomeMath is a small set of free calculators for the biggest housing question: can I afford this, and is buying or renting smarter where I live? We cover mortgage payments, rent-vs-buy comparisons, and affordability, plus city and state versions with local tax and price examples.

Every tool runs in your browser, so the numbers you type never leave your device. The tax rates and home prices we show are typical published values, clearly marked as examples — your real numbers come from a lender or local listing.

HomeMath is a planning aid, not a lender. The formulas (loan amortization, the common 28%/36% affordability guideline) are standard, but always confirm with a mortgage broker or bank before you act.
