By definition, these type of loans are not the same quality as what is traded on wall street. 

@Jaron Walling Thank you for the response.

I'd personally say pulling your water heater out and replacing with a wall mount on demand one, would be worth the cost to have in unit washer dryer if you are staying there or renting it, it would be worth it.its always worth doing the big stuff well and correct even if you are cleaning up after someone, the long term hold always prevails, its just a little frustrating front sometimes, but hang in there!

The only way they would seriously consider a higher offer from an unqualified buyer is if they have no offers from better qualified buyers and their back is against a wall. 

Job included inside work of leveling floors, installing flooring, paint walls, kitchen cabinets, etc in both units, as well as lay a new driveway, fence the back yard, provide attic fans, and install electric to the crawlspace to add lights and a sump pump.

Also, many PadSplit properties have bedrooms that are created via flex walls that wouldn't meet the definition of a bedroom in an appraisal, so many PadSplit owners may think their property is worth a certain a mount based on a bed count that's not valid. 

It’s a 2/1 750 sf house built in the 1920s with  a concrete wall foundation and partial basement.   

Why would you want to keep it "behind the walls"?

@Jaron Walling, Thanks for that shout out. 

Windows would be my next check-point (less than R1) and then wall insulation: I would not be surprised if they have no insulation inside, but you can do blow-in, which only requires a small hole.A home looses heat in two ways: heat conduction (which you can slow down with insulation) and drafts, which in old houses is usually the biggest culprit.
