I have viewed some auction sites, but have read very mixed reviews on whether or not they are reputable.

Along the way the GC and subcontracted plumber mentioned numerous times that they found great news or thought of more efficient solutions (i.e. the mainline plumbing under the basement was intact--that they had assumed was all broken and needed replacing).

Is there an all inclusive website that is reputable that you would recommend?

I am currently a W2 employee working as a plumber/ gasfitter.

I suspect they are not going to take any risk for a few hundred dollars in title and escrow fees so they will stick to their 2 year minimums.there is a company in CA I believe that specializes in insuring these..i checked into this on a lot I had in Charleston SC that I was having a hard time getting insurance for.. but when I read there policy it was clear .. no lender ( construction lender ) at least a bank would rely on it.. and I highly doubt a reputable mortgage lender would rely on that title insurance..

Any reputable QI would not let you do that hopefully. 

Come spring, I will have a plumber/hvac tech rough in all 6 gas lines for propane and then replace the furnaces in the summer/fall.  

Better for gaining a reputation as a landlord that will work with their tennants rather than one for being a hard ***. 

A reputable - reliable - affordable contractor(s) is very important, too.

THe plumber charged $240 to respond and clear the line of paper towels.
