That drive the market down further. If people think prices will fall further they will put off a home purchase even if they are ready to buy. this downward pressure means people who want to sell their house to move to another house can't sell the house they are in. and this creates a downward spiral. Home sales are up. Both new homes and existing. http://www.realtor.org/research/research/ehsdata
So don't believe the hype. Four months in a row is a trend. Your home price will only go down if people stop buying homes in your area. Simple economics of supply and demand. So if you spread fear an buyers stay on the sidelines, your fiction becomes reality. or in other words life imitates art.
