Home prices increased in June over May in 23 out of 25 areas surveyed by real estate data company Radar Logic. Sales in the most expensive zip codes, based on median home prices, made up a larger percentage of total sales since the beginning of 2009 than in previous years. The number of sales requiring jumbo loans increased, so jumbo transactions now make up a larger share of total transactions, according to the report. In Manhattan specifically, condominium prices rose 3 percent in June but remained 13 percent lower than their year-ago level, according to a separate Radar Logic report also released today. Transactions were down 42 percent year-over-year, and per-square-foot prices also fell, the report says. TRD
