Property is a block off North Ave about 0.8 miles from tech.

The problem is that it is Aurora, CO- one block outside of Denver and all licensed contractors are booked out for months and charging what I consider outrageous prices per books/online estimates I've came across. 

Also, she threaten to put cement down the drains and to burn the place down.

I have a 15unit a couple of blocks from there.

Downtown Rside can be very block by block (1st street to 10 street), but they are definitely adding a lot of new things to main street and mission inn area.

And it is quite a challenge to find the right banker at these banks to talk to.The home I mentioned, bought as an REO, there were four adjacent ones on the block, and two of them the owners bought directly from the bank, from what they tell me, so as you say, is not unheard of.

Signing the waiver will block you from getting a commission because you will be in violation of several state rules and probably the licensing act itself if you say you are only an investor while acting as a broker.

I have sprayed tubs with epoxy paint using my Porter Cable pancake - just remember to drain all the water out first and/or get a water trap. 

One of my houses has a cracked sewer pipe so the tenant can't use drains.

There is a cabinet in the hallway that allows for inspection of the plumbing, and after further inspection, the joist that the shower sits on is cut to allow the drain line for the shower to fit.
