The second set of tenants were very patient as I worked on getting the unit up to my standards while they were moving in.Unfortunately I did have a pretty bad experience with a handyman/contractor during that last turnover.

Perhaps this is standard in your area, but I'd definitely shop around if you haven't already. 

An inch of spray foam directly on the structure will seal any potential areas of infiltration followed by standard blown in insulation on top to make up the balance of the R value required.  

Does this depend on the location or do we have a standard rate for all?.

I am working in Baltimore in the cybersecurity field.

I like to rent mobile homes, but have a standard, the biggest is to sheet over the floors with plywood.

Most banks don't know the standards changed and will not do more than 4 loans, but recently I found a few that will. 

In this situation would probably just want a standard PM agreement, if I was you.There isn't any equity to split and paying for repairs seems like throwing good money after bad.

If the builder won't let you put in a contingent offer then just put in a normal offer, conditioned upon obtaining financing which is standard in any contract.

Good ideas here even for a standard close.
