WASHINGTON — US home prices held flat on a seasonally-adjusted basis in January, as the prior month’s gain was revised lower to reflect 0.1 percent growth from a previously-reported 0.7 percent increase, the Federal Housing Finance Agency (FHFA) reported Thursday.

Analysts were looking for a 0.3 percent uptick in monthly prices, according to Dow Jones Newswires.

Home prices fell 0.8 percent from the same month in 2011, the FHFA said.

The FHFA monthly index is calculated using purchase prices of houses backing mortgages that have been sold to or guaranteed by Fannie Mae or Freddie Mac.
