WASHINGTON (AP) — Prices for U.S. homes rose faster in May than they have in 17 years as surging demand for housing outstripped the supply.

The S&P CoreLogic Case-Shiller 20-city home price index, released Tuesday, soared 17% in May from a year earlier on top of a 15% jump in April. The May increase was the biggest since August 2004.

The hottest markets were Phoenix (where prices surged 25.9%), San Diego (24.7%) and Seattle (23.4%). All 20 cities reported faster year-over-year growth in May than they did in April.

The U.S. housing market has been hot. Many Americans, tired of being cooped up at home during the pandemic, have traded in apartments and small homes in city for bigger houses in the suburbs. The Federal Reserve's easy money policies have also kept mortgage rates near historic lows, pushing up demand for housing.

The supply of houses for sale has been limited, partly because many Americans are reluctant to put their properties on the market and allow would-be buyers to troop through their homes.

But rising prices have pushed many would-be buyers out of the market. The Commerce Department reported Monday that sales of new homes fell in June for the third straight month, sliding to the lowest level in more than a year. Last week, the National Association of Realtors reported that sales of previously occupied homes rose in June, snapping a four-month losing streak.

“Price pressures remain very firm and appear ready to stay that way in the months to come,’’ said Matthew Speakman, economist at the real estate firm Zillow. “Indeed, sharply rising prices do appear to have priced out some home shoppers, particularly those looking to enter the market for the first time, and causing fatigue among would-be buyers. But overall demand for homes remains very firm.’’
