Then I would take my 4 x 24 belt sander with an 80-grit belt in to that area and sand slowly until I got down to bare wood.I would then use my trusty pry bar to rip up any additional pieces that are too heavily damaged to salvage and throw them away.I would then measure and cut pieces to replace the missing pieces out of 3/4 in. oak boards with fine-cutting blades in my table and miter saw.

The high sand content of the brown coat will dull the blades fast.

I am a newer investor, so please take my advice lightly.As you are trying to contact the owner, consider running the numbers a few different ways, as an educational exercise.1) Blade / RebuildMake a few calls to get an estimate for blading the current house, and then do the same for a new construction that would fit well with the neighborhood comps.2) Rehab CostIf you have a friend that is a contractor, buy her / him a nice lunch and go tour the property together.

A cupped diamond blade on an angle grinder would do the trick (with a lot of dust) You would not have to go  completely nuts on existing tile just enough deep scratches for bonding and not lying awake at night wondering if a tile will fall off the wall and hurt someone.

To quote WWII Admiral Isoroku Yamamoto, "I would never invade the United States, there would be a gun behind every blade of grass."

Then you have your general tools like a vice grip, hammer, channel locks, flashlight, tape measure, composite shims, headlamp, box cutter with extra blades, painter's tool 5-1, wire stripper, allen wrenches, voltage detector, outlet tester, lineman's pliers, good Milwaukee demo screwdrivers, Milwaukee 11-1 with Phillips, flat heads, and 3-4 common size nuts(this is great for appliances).

Using blades on the lawn or propellers in the sky is one thing, but if you're going to do it, you've got to wear a suit.

I am realistic that you may not be able to remove the 90's, but - if possible - making things straighter will make 'em better.2) I recently cleaned out our dryer vent with this thing off of Amazon.

Glue, blades, buckets, tapes, etc.
