For a long-term solution, I would pull the cabinet, cut open the wall, increase insulation, then put it back together.

The contractor also mentioned that this same area has been repaired before, he saw dry wall cut lines in the same area he has to now repair.

We installed a 20' steel beam to open the back section with two 18' wide garage doors on either side.

Finish the list, it got cut off.

I wrote a check from the LLC bank account once a year for the property taxes and few to landscapers to cut weeds. 

Asbestos, old electric (esp. knob & tube), and old plumbing (like galvanized steel) are the other main issues...but, I wouldn't not buy a property simply because it had old electric, old plumbing, asbestos or LBP  (I've bought many properties with these issues).

@Dillon LeRoy Pollard If you really want this it's not that hard to cut expenses and earn some side income in order to build your cash. 

On a fixed interest rate loan, can the bank come back and say, “oh 3% isn’t cutting it anymore, we want 7% now” 15 years into your fixed rate mortgage?

@Mary Jay Hey Mary, it is going to depend as there is no clear cut answer without knowing your personal financial situation.

The point I’m arguing is that the realtor who goes above and beyond for a 50k property to get it to sell before the city auctions it due to unpaid taxes, which is the situation I’m in, deserves a bit of a pay bump.  3% of 50k won’t cut it for the extra work/marketing that will come out of pocket.
