sound like a normal slab on grade. have the floor cut and replace the galvanized pipe with PEX, but run it through some schedule 40 pipe, maybe 3". this way if it ever has to be removed it can be cut, pulled out and new one pushed back through. i do not recommend running the pipes through the attic, i'm sure Georgia doesn't get that cold, but something may happen to the lines if they are up in the attic and cause more damage below. plaster walls can be patched. while you are at it check the waste lines, if they are cast iron, check the condition and replace if you can, that would be the time to do it.

Like I said, rent to cast ratio. :)How is the market in Oklahoma City?

I watched my first web cast today! 

And thanks for doing that pod cast.

@Michael Anspach, I really like Pocket Casts for Android.

Cast aluminum and stainless steel fastenings only for beach areas.

These can be cast to made to look like granite for a fraction of the cost.

Reasonably intelligent people will question but not use innuendos to cast others in a bad light.

I always say go work on a car lot for 6 months before you send out your first yellow letters.. and or listen to Quarles pod cast you think that dude does not know how to sell..
