Actually, if developers start going BK it will be much worse than you think.
Municipalities require that developers post bonds that guarantee the on- and off-site subdivision improvements (street, sidewalk, sewer, etc.) will be installed by a certain date AND maintained until the lots sell. If the developer can't complete the improvements, the municipality has the right to call on the bonds and force the insurance company who underwrote them to install the improvements or pay the penal sum of the bond.
Insurance companies/Sureties stand to lose billions if developers continue to go BK and can't have the Subdivision Improvement Agreements amended to allow for more time. Some of the biggest players in this market are Zurich, Travellers, and AIG. Seriously, do you think AIG can withstand another multi-billion dollar hit? How many of you will lose health or accident insurance if Travellers goes under? Zurich (Farmer's Insurance) is a big player in P&C.
I'm pretty anti-bailout in any form, but don't think that this is just a 'developer' problem. If subdivisions continue to sit unbuilt (is that a word?), the surety bond industry could be decimated (which is bad, since the Miller Act mandates that the surety industry exist).
