If the gains of the past 12 months in housing prices throughout the 209 region occurred prior to 2006, there would be dancing in the streets.The median price for closed escrows of previously owned homes have jumped from the lower end of 11.6 percent in Turlock to a region-leading 40.1 percent in Manteca during the past year.Prices still have a way to go before they reach the historic peak of 2005.For Manteca, that was $429,000. That is a $173,000 gap that still has to be covered given the median price of homes that have sold in Manteca is at $256,000. That’s up 40.1 percent from the year’s prior median of $184,500.It’s a given that most houses are still selling below replacement value in terms of construction, development fees and land costs.
