Brentwood and Eastern Contra Costa County housing prices are down 60% and greater from peak prices of 2006-2006. Prices of many Brentwood area homes are nearing $100 per square foot, lower than the cost to build. In addition, the monthly payment for the purchase of many Brentwood properties is less than rent, a great opportunity for first time buyers. The bottom is hard to predict, but it is a great time to buy and own a home in Brentwood.
