They will be able to make a determination of what is causing the settling and what the best path is to remedy it.

I haven't seen evidence of mold anywhere else in the property.I would like to fix this myself and avoid using remediation people if at all possible.1) Is the best course of action just to cut out those parts of the drywall/board that have it, so I don't risk contaminating other areas, rather than trying to scrub it off?

However, with a judge involved in the process, rights of redemption and other equitable remedies can be asked for.

Does it need a new roof, new siding, all new sheetrock, mold remediation, etc?

There were always problems with  insurance and the enormous cost of remediation.

If an agent/broker fails to comply with the agreement or makes false representations in the agreement then the buyer may exercise any remedy at law.

That part of town was arguably ground-zero for the foreclosure crisis in Atlanta, but there has been a concerted push to spur revitalization by coordinating public & nonprofit investments (City, BeltLine, EPA brownfield remediation funds, HUD, DOT, Annie E.

Can it be remedied by choosing certain quality paint or certain (I suspect dark) colors?  

-  Etc...Those aren't things that can be looked up on the Internet, and often require several projects before you truly get a sense of what works and what doesn't work.For example, it took several projects in Milwaukee before I truly understood how buyers viewed foundation issues (much of the city is built on expansive soils), how contractors approached foundation issues, and how much it cost to fix the various different types of foundation issues all my houses there had.In Maryland, it took several projects to before I truly understood lead paint issues (Baltimore has wrestled with lead paint more than most cities), how and when it needed to be remediated, and the most cost-efficient ways to remediate.In Atlanta, it took several projects to learn how to negotiate the various permitting and inspection authorities.
