you are f#@%ed" Lines are buried in the concrete along exterior brick wall..

Where I live, it's not uncommon to see a handful of basement jack posts either on concrete pads or on the dirt itself to deal with soft spots on the foundation, but the soil here is thick, heavy clay with solid rock close to the subsurface, so there's not a whole lot of movement.

specifically I was thinking about general cost on plumbing and drains on a 50x150 lot w alley sewer access and say a 30x50 or 30x60 by 6 inch thick concrete slab.

It is best to have pictures and be very concrete and specific about what is damaged and what is charged. 

I do epoxy floors and concrete polishing (Full Mechanical) and  I tell people all the time that the coating I put down is only as good as the surface it is applied to. 

If you buy the note, you are going to have to complete the foreclosure process (attorney fees), pay back taxes, and worry about the current owner pouring concrete down the shower drain.

My favorite is stained concrete.

Just yesterday, I replaced a section of 3 inch sewer pipe from the ceiling in a garage, down a wall and replaced 15 feet under the concrete garage floor.

When we began chipping off the old 4x4 tile on the bathroom walls we found a slab behind each wall about an inch thick of concrete to which the tiles are adhered to directly.Is there an easy way to remove the tiles or should be just demo the entire slab, tile and all and just replace with 1/4" concrete board on the remodel?
