I have heard that inspectors need a special certification to inspect that stuff.

There are 20+ CPAs and accountants on this site that specialize in real estate taxation.

I would use the comps as a broad guide, but then verify the data with a broker who specializes in a certain area.

South Carolina is really good as well specially if you go to small towns outside of big cities. 

I would recommend speaking with an attorney who specializes in asset protection if you wish to go that route.Any of the solutions available to you come down to how risk-adverse and price-sensitive you are.

And if they sue you personally, you can have it dismissed because the lease, house,  etc. are all with the Trust.Personally, I have a Trust for my houses--the one I live in, second house, house my special needs adult daughter live in, and 2 other trusts for rentals (higher risk rentals in one, lower risk rentals in the other). 

Does anyone have a recommendation for a legal advisor or attorney who specializes in real estate and multi family rentals?

I currently own a Property Management company that specializes in Boutique Hotels and Airbnb rentals. 

You can have a master servicer, special servicer, general servicer and they can all do different functions.

He is now the director of scheduling for a local company that specializes in large multi unit builds.
