I usually will put up a vapor barrier over the studs, then concrete board or green drywall, then I use a waterproof membrane such as Kerdi.

Cracked drywall or plaster is nothing; severe cracks in poured concrete walls another matter. 

I would say one concrete piece of advice I would give is to benchmark the types of rehabs people are doing in your area, and what those houses are selling those rehabs for.

Concrete For Foundation Poured Without InspectionThe subcontractor my general contractor hired to do the foundation had 20 yards of concrete poured today (35 degrees all day and part of the concrete is surrounded by a 3inch pool of water).

Let me know who else out there are the investors with nerves of steel playing in the concrete jungle that is NYC and do connect with me!

By the time he does that and I patch the concrete floor and retile everything I bet I’ll be out about $5000.Do I have any legal ground to stand on go to the prior owner and ask for compensation for these defects that were hidden from me at the time of the sale?

And by "raw" I do mean polished as well, cause they do have the actual raw slabs that aren't polished.

I didn't open it to make money ;)Domy is Polish for 'homes' so it has great meaning as I intend to hold SFR and small multi's in it.

So, now I've gone from a cashflowing property to a property that's costing me a mortgage payment every month and needs over $50k of work (the only way to fix the problem was to demo all of the flood damaged drywall, cabinetry, and  trim, jackhammer through the slab, excavate and remove over 5 truckloads of concrete and clay (by hand), install and plumb an industrial level sump and irrigation system, backfill it with rock (by hand), re-pour the slab, and re-finish everything.How is this relevant to your question?
