Since you bought
How much has your home gone up since you bought it?
Type what you paid, when, and your ZIP. You get today’s value if your home grew like the homes around it did, with the government index numbers and the math right beside it. No address needed: this is not a listing-site estimate, which by Zillow’s own accuracy figures misses by several times more when a home is not for sale.
- Federal data. Every figure is from the FHFA House Price Index, a public dataset.
- Math on the page. Your price × how the index moved. Nothing hidden.
- Nothing stored. No address, no account, no listing pitch.

What this cannot know
- Your house. The index is the average of repeat sales in an area. Renovations, condition and lot are not in it.
- Every sale. It is built from conforming mortgages bought by Fannie Mae and Freddie Mac, so cash, jumbo, FHA and VA purchases are missing.
- Small areas well. FHFA calls its county and ZIP indexes “developmental”: fewer sales, more noise. The page says which level it used.
- What a buyer would pay. It is not an appraisal, and it will not tell you when to sell.
Read before you use it
- Does the Area Level Change My Home Equity Estimate? ZIP vs State IndexEquity is value minus balance, but the area index you pick moves the value. One 2014 Austin purchase gives $422,407 on a ZIP index and $500,230 on Texas.
- Which States’ Home Prices Rose Least in the Past Year? A 1-Year vs 5-Year LookState home price change over the past year beside the five-year figure, from the FHFA index through 2026 Q2, with a Colorado purchase worked in dollars.
- Why Your Property Tax Bill Differs From the Effective RateThe county rate is one median bill over one median value. Assessment ratios, exemptions, caps and district millage put your own bill somewhere else; here is how.
