FHFA notes: The FHFA HPI is a broad measure of the movement of single-family house prices. The FHFA HPI is a weighted, repeat-sales index, meaning that it measures average price changes in repeat sales or refinancings on the same properties. The line is FHFA's standard quarterly all-transactions index; the comparison table uses FHFA's annual state index from the same family. The index does not give a dollar value for any home.
Maine's FHFA house price index starts in 1975. Through 2025 it has risen +1126.0%; over the ten years to 2025 the rise was +112.4% (+7.8% a year), well above the national +85.0%.
The quarterly index through 2026 Q2 is +3.2% on a year earlier and +1.0% on the quarter; nationally +3.0% and +1.1%.
The index peaked in 2007, fell −14.4% to 2012 and regained the peak in 2018; the national index fell −21.3% over 2007–2012.
6,830 housing units were authorised in Maine in the 12 months to August 2026, 4.8 per 1,000 residents against 4.1 nationally; that is +8.4% on the previous 12 months. 16 counties, 4 metro and micro areas, 196 ZIP codes and 161 permit-issuing places in the state have their own pages.

FHFA reports each index with a value of 100 in its base period, the first year the area has enough transactions (1975 here). A decade's change is the index at the end of the decade divided by the index at the start, so it does not depend on the base year; the United States column covers the same years. Decades before 1975 are not shown.
Peak-to-low declines

Purchase-only index
FHFA also publishes a purchase-only index, built from sales prices alone (no refinance appraisals). It starts in 1991 and is drawn here on its own base.
