The April reading
The Federal Housing Finance Agency reported that its seasonally adjusted monthly House Price Index fell 0.1 percent in April 2026 from March, and was up 2.0 percent from April 2025. The release was published on June 30.
A 2 percent annual increase, against consumer price inflation running above 3 percent for most of 2026, means the average financed US home lost value in real terms over that year even though its nominal price was higher.
What makes this index different
The FHFA HPI is a repeat-sales index built from mortgages purchased or guaranteed by Fannie Mae and Freddie Mac. It compares the same property to itself across successive sales, which removes the composition effects that push median-price series around.
Its coverage is also its principal limitation. Because it is constructed from conforming, conventional mortgages, it excludes cash purchases, jumbo loans above the conforming limit, and government-insured lending. High-cost coastal markets and the all-cash investor segment are therefore underrepresented relative to their share of transactions.
Three indices, three numbers, one market
Readers encountering FHFA, Case-Shiller and NAR figures in the same week are looking at three different constructions. NAR reports a median sale price, unadjusted for mix. Case-Shiller is a repeat-sales index weighted toward 20 large metropolitan areas and inclusive of jumbo and cash sales. FHFA is a repeat-sales index restricted to GSE-backed loans and national in coverage.
Analysis: the consistent finding across the two repeat-sales measures through mid-2026 — low single-digit annual appreciation — is stronger evidence than any single release, precisely because their samples differ. Where they agree, composition is unlikely to be the explanation.
Revisions
FHFA revises the monthly index as additional transaction records arrive, and month-over-month figures for recent periods are the most likely to change. The agency publishes the full history with each release.
For that reason the annual comparison is the more stable of the two numbers in any given month, and a 0.1 percent monthly move should not be treated as a directional signal on its own.
The divisional spread
Beneath the national −0.1 percent, the nine census divisions ranged from −0.8 percent in the Mountain division to +1.0 percent in New England for the month. Over twelve months the range ran from +0.2 percent in the Pacific division to +4.4 percent in East North Central.
That is a four-point divisional spread around a 2.0 percent national figure, and it repeats the pattern visible in metro-level indices: interior and eastern markets appreciating while western markets stall. Analysis of the same release found Illinois leading the states at 7.3 percent annual growth, with prices up year over year in 42 of 50 states and in 65 of the 100 largest metropolitan areas.
The March figure was revised from an initially reported +0.1 percent to +0.2 percent in this release, a reminder that single-month readings in this index move. FHFA scheduled its next release for July 28, 2026.
