Or look into colored concrete if there's concrete floors underneath the current stuff.

I do have some experience with rehab projects, I usually worked on my friends and family condos (never houses)..scope of the project usually included light plumbing jobs (new faucet, sink, connect plumbing underneath the sink, light electrical job : installing new fans, demoing non-load bearing walls, framing around pipes ducts rewiring/running romex from point A to B, new flooring – allure, painting, light carpentry like installing new cabinets, overseeing granite installations, tiling work etc).

The unstable soil around here can cause foundation/plumbing/ roof costs to jump quick if you under estimate.

I spoke to another investor and he said that it is difficult to find a level home in San Antonio because of the soil.

I discovered hardwoods underneath, but a larger corner of the living room (where you first step into the house) is covered in floor leveler, which was needed at some point in the past where the floor had sunk.

I am guessing(only guessing) that since this is a slab foundation, and you indicate there are issues with other houses in the neighborhood that these foundation damages are due to shrinking and swelling of active clay soils.

And I don't want to break the nice marble tiles to show the pipes underneath just for inspection.

Georgia doesn't have soil so much as it has a lot of clay and rock, so digging and waterproofing is rather an expensive pain in the butt!

I've seen issues with using CPVC in areas where rodents, or squirrels are an issue, or where there is a crawl space underneath (presumably giving critters easy access to the pipes).

Long story short, he would not redo the roof, so it cost me another $11,500 to have the new roof pulled up and replace the rotten wet boards underneath.
