How we estimate this

annual income × 36% = maximum monthly housing payment
− estimated property tax − insurance − PMI (if down payment < 20%)
= available principal & interest → estimated affordable home price

The 36%ratio is a simplified rule of thumb, not an underwriting model — it doesn't account for other debt, credit score, HOA, utilities, maintenance, or lender-specific requirements. No debt-to-income input is used; the ratio applies to gross household income only.

Frequently asked questions

Is this a San Bernardino County home affordability calculator or an estimator?

This is an estimator, not a calculator. It applies a 36% housing-cost ratio to your gross annual income, then subtracts an assumed property tax, insurance, and (if applicable) PMI amount to work out an estimated affordable home price for San Bernardino County, California. That's a simplified rule of thumb, not a lender's underwriting decision.

Why is this an estimate instead of an exact number?

San Bernardino County's effective property tax rate is real, county-specific data. The mortgage rate, insurance, and PMI figures are national assumptions, and the 36% ratio applies to gross income only — existing debts aren't factored in. Your actual affordable price will vary based on your credit, loan type, lender, and personal finances.

Where does this data come from?

San Bernardino County's typical home value comes from Zillow Research's Home Value Index (ZHVI). Its property tax rate comes from the U.S. Census Bureau's American Community Survey, as compiled by the Tax Foundation. The mortgage rate assumption comes from Freddie Mac's Primary Mortgage Market Survey (PMMS).

Why are home prices so far above the affordable range in San Bernardino County?

San Bernardino County's typical home value is well above the national median. High-cost counties like this typically have housing supply that hasn't kept pace with demand, which pushes prices above what a household earning a typical income can afford at conventional lending ratios. That gap between typical income and typical home price is real and shows up directly in the estimate above.
