MADRID, Sept 9 (Reuters) - Spanish house prices fell 4.6 percent in August from the year ago month, marking the sixth month of decline after the global credit crunch burst Spain's housing bubble, an industry report showed on Tuesday.
The drop followed a 3.9 percent year-on-year fall which the report's publishers, real estate valuation firm Tinsa, recorded for July.
Spain's Mediterranean coast -- which has seen massive building over the last decade for foreign buyers -- was worst hit, with prices slipping 8.3 percent, Tinsa said.
Prices in metropolitan areas slipped 7.1 percent while those in regional capitals and large cities declined 5.7 percent, Tinsa said.
Spanish house prices are expected to fall between 20 and 30 percent in real terms over the next four years due to chronic oversupply and a prolonged economic slowdown, according to banks and real estate companies.
