I would recommend talking Mike Florence in Sandy Springs but the right borrower is more important than the paperwork.

Root cause is the slide area and estimate of having to do $25,000 just for soil test to find out where (or if) there is solid ground.

I'm looking for a place within 10-15 miles from Sandy Springs with about $150K total cost.  

I build homes in Dallas TX which is notorious for poor soil which in turn leads to many foundation issues.

Online research points to 'filtration soiling' and it seems to be somewhat common down here (NC).

Does anyone in the Carolinas, Florida or New York/ New Jersey area have experience with a similar issue after Matthew or Sandy?

Unfortunately, the disaster relief usually isn't enough to put the house back into the same shape as it was before.After Sandy, many homeowners stayed in their homes or stayed in hotels and kept their homes while waiting for relief funds.

Subterranean termites need to be killed where they live, in the ground.Remember that wet soil will also attract termites - so look for pipes leaking and plants/mulch that stay wet close to the building.In Florida, a wooden building that hasn't been treated for termites recently... has termites.

Both were kinda sandy and brittle.

so if soil changes, you can just tweek the piers?
