When it is set, yet still has moisture in it, it can be scraped to smooth so that top coats go on nicely.

In other words, the cost of preparing the area, breaking tiles, cutting open the slab, excavation to the pipe, backfilling with clean fill, termite pesticide application, moisture barrier, rebar epoxy to old slab, pour new slab, new tiles are all covered, the $150 to fix the actual leaking pipe was not covered.I had a collapsed fitting under the house confirmed by camera. 

I have had some really ugly laminate flooring in kitchens and baths as water always penetrates the seams and causes them to buckle and peel at the edges.

The real estate market will probably be difficult to penetrate from a distance and be competitive.

The tenant had just notified me that this crack has appeared in the bathroom ceiling,  No moisture appears to be in the ceiling.  

Is there any chance it's not a stain from the mat from above but moisture/mildew coming from the subfloor?

It limits the wall penetrations and it will not cause an issue if you decide to go a different direction in the future.

The drip edge wasn't installed properly and they put the hardy on the eves with no osb or moisture barrier behind it.

@Frank Sanchez Hey Frank, before you buy keep in mind a few things: the moisture/humidity/mold in the  crawl is a dynamic thing.

Crawl space isn't a typical breeding ground for fleas, but it could be if there is a lot of junk and moisture down there.
