Very encouraging and I like the way you have it broken down into steps.  

For example he knocked out a wall and the old broken kitchen cabinets.

We all say on here, 90% of the time, it's not worth going after a tenant who has abandoned a property or broken a lease because it costs too much.Also the cost to evict a m2m tenant is the same as a lease tenant, because if they don't want to leave you still have to pay the same costs to evict them.

I'm an out of state landlord and I'd like to sell my last property off in Broken Arrow. 

I hate sounding like a broken record, but I just think it is good advice.What ever you use, get a website going WHILE you do your DM marketing.

These included under sinks, inside electrical boxes, plumbing joints, insulation, roof shingles, broken window seals, the whole nine yards.IF, you trust they’re doing a thourough job and charging $100 or less, MAYBE I would keep using them.

Hold her to the lease and advise the ex to get a restraining order, problem solved.Bottom line is that by her leaving the lease is not legally broken unless he leaves as well.

My agent doesn't work for any other investor and my agent has since broken away from the other investor.

I have gutted more house/cabins that had a broken pipe that where vacant for a month plus. 

YOU must fix all the items that they have broken before the inspection otherwise YOU are in violation of the lease and it will not be renewed.I try to have a little nicer house or apartment than others in the area.
