The size distribution of homes in 4S is simply a decision of the builders of what to build. It really is what it is… 4S is characterized by a high housing density where most all of the homes take up a large percentage of the lots. I believe the construction is overall good quality and do not classify it as subpar as others do. Yes there are isolated areas where there were some foundation issues but the vast majority of 4S is good.
While there are going to be continued foreclosures in 4S the bottom for that area came and went awhile back with regards to the 2500-3000 sf homes. I think you will see continued foreclosures there but due to the manipulation in the market with respect to continued low interest rates and other shenanigans we will see fairly poor inventory levels. As to when the properties will hit the MLS it is anyones guess. The path through the default process is as slow as ever and the efforts to keep people in homes is as strong as ever and even more effort will be put forth this year to enable them to stay. If you find something you like and can afford it, then you should probably move on it. If you have a few years to wait then hold off because prices will not start to depreciate until we have interest rate movement that is non trivial.
