Here's the latest, this from a Fannie Mae document that can be found here. While there's tons of interesting data, I picked these two charts to highlight, because they represent data I had been looking for.
Notice the rising inventory of new homes - BAD BAD!
Rental vacanies have been rising, suggesting a surplus of homes. While this could be because of the mania of individuals trying to buy new homes, and we might see this number drop as the bubble cools off, the levels are worrying given the level of debt. In my city (Charlottesville, VA), apartment complexes are cutting rents by as much as 30-40% due to oversupply of homes.
