If you build a crawlspace foundation and cover the foundation with an upside down U shape piece of galvanized metal, the termites cannot get past it. Their moisture causes a small electrical shock when they come in contact with it.

In addition, you can have ACQ lumber as the mud plate and the bottom of the wall frame that will serve to keep them out.

Termites love moisture, and if you keep that away from your foundation that is a deterrent against them.

As far as when it would be best to build your homes, not every part of the country is in a building recession. In fact, some of the eastern seaboard states are actually doing quite well.

One state, California, accounts for 50% of all failed mortgages, Stockton being the worst city in the country for repossessed homes.

I don’t want to discourage you with my suggestions. Good Luck in perusing your dreams.
