Estimates only. Sample figures for illustration, not a loan offer. PMI is estimated at the rate you enter and removed at 78% of the original value; FHA uses a 1.75% upfront premium and 0.50% to 0.55% annual MIP; VA uses the first-use funding fee. Your first year also brings a supplemental tax bill, and taxes and insurance change over time. A Loan Estimate shows your actual terms.
How to read this
Four things the calculator assumes, so you know where it stops.
Property tax here is estimated at 1.25% of purchase price, which is the sample rate this demo uses for Santa Clara County including typical bonds.
Your first year also brings a supplemental bill based on the new assessed value. Budget for it separately.
Insurance on a single family home in this county commonly runs $120 to $260 a month as a sample range.
Below 20% down, mortgage insurance is estimated from the PMI rate in the extra options, removed at 78% loan-to-value. It commonly runs $150 to $400 a month depending on credit and coverage.
Working backward from income instead? Use the affordability calculator. Already own? Try the refinance break even.
