@John Steffen, any chance you still have this list?

That means there are higher chances you will find someone who can do a good job at installing it vs using a less installed LVP connector system. 

I hated it so much that when they offered to keep me in my unit (which meant no chance of going to Iraq or Afghanistan), I turned it down and chose the combat zone options instead. 

I would start by getting a foundation guy there to give you an estimate for his repairs.

Theoretically more Mods means more chances of catching stuff, so more help is generally always welcome, but no one should expect miracles. 5.

But zero chance I would pay the extra to sell to this one buyer or expect debt to be forgiven. 

They provide free estimates and work with your accountant.

I had an estimate done ($7k) because at this point the sprinkler piping is exposed and I'm afraid that could lead to an even greater problem.

Times change, markets change, interest rates change, but we still hear about these same old "rules" decades after they lost their relevance.The same logic applies for napkin math rules that say that capex, vacancy, repairs, or whatever, should each be estimated at X% of monthly rent. 

The BP rental estimator tool is pretty good as well and is usually within about a 5-7% margin of error.
