Before we look ahead, it would be good to start by looking at where we are currently.
People wanted to achieve their “American dream”, which is really one of two things. Either it is a “rags to riches” story, or buying a big home. Congress pushed all kinds of programs to achieve more than 70% home ownership. Some of the programs were specially designed to increase homeownership among low income population. There is nothing wrong in these goals, but nobody paid attention to the means that were employed to achieve those goals. It almost became “by any means necessary”, and lending and underwriting standards went by the wayside. The result – a significant increase in number of foreclosures and defaults among mortgages and all kinds of mortgage related derivatives as people couldn’t afford outsized mortgages they had taken on at “teaser” low rates.
Mounting losses among banks increased counterparty risk to such an extent that banks stopped lending to anybody, not even to the most credit-worthy banks leave alone ordinary citizens. “Toxic Assets”, as they became known, jammed the whole economy which depends heavily on free flow of credit. As credit dried up, it became increasingly difficult for people to re-finance their mortgage and escape increased payments. This contributed further to foreclosure and defaults.
Combination of grinding halt to the economy, drying up of credit, and increase in foreclosures put significant downward pressure on the housing market and home prices. As we can see in the graph below, FHFA housing index was at its highest level in 2nd quarter of 2007. Since then it has decreased by more than 10%. FHFA Index is seasonally adjusted for purchase-only homes that were “conforming”, i.e. they met guidelines set forth by Fannie Mae and Freddie Mac.

Case-Shiller and FHFA Indices
S&P Case-Shiller Home Price Index is more sensitive to home price changes as it includes all home sales and not just conforming ones. Since its peak in 1st quarter of 2006, S&P index has declined by more than 31%.
So what about the forecast?
I believe that the factors that caused home prices to go down will again play a significant role in reversing home price decline. Just to summarize again
1) Economy: It needs to show signs of recovery. GDP change needs to move into positive territory to give people confidence to spend on big purchases, such as housing.
2) Credit Availability: Banks are already showing signs of increased risk tolerance after their initial pull back. The pendulum had swing too far the other way. Banks need to make decisions based on credit worthiness of the borrower rather than fear.
3) Foreclosures and Defaults: First, the inventory of foreclosed home that are putting downward pressure on home prices need to be depleted. Second, further foreclosures and defaults need to be reduced so that inventory does not build up again. Government has already initiated a number of programs to modify and refinance loans to prevent foreclosures. I believe these programs are definitely a step in the right direction.
All together, I believe that credit is already becoming available. Foreclosure inventory should continue to go down and may take 6-12 months to clear out. Economy, on the other hand, might take much longer time to recover. It also looks like it maybe a jobless recovery, with economy getting better but taking much longer to reduce unemployment. This delay in economic recovery and delayed reduction in unemployment may push improvement in home prices towards the tail-end of 2010 or early 2011.
