It's definitely the cheapest option.Mini splits require some amount of duct work if you are going to serve more than 1 room on the other side of the wall from the unit.

The easy answer is simply a 240volt plug on the wall.

Keep a door between units, or maybe have one wall that is easy to remove that opens it back up.

This isn't like a court battle where everybody has their back up against the wall ... trustee and lender may be willing to work with you.As the property owner you have the right to protect your interest by reinstating the existing loan, that's not to say the lender, after reinstatement, can't start a new foreclosure based on a violation of the due-on-sale clause, but may not. 

If you rent the condo out to others it would be the same thing -- you would need a policy that only covers the interior walls -- it would be an HO6 tenant occupied and depending on the carrier you currently have you would either change the occupancy status or you would need a different policy-- in my experience 9/10 times they require a different policy. 2.State farm does not really ask a lot of questions -- their quoting process is not as in depth as it should be.

I don't have funds for the roof, or to replace the outside supporting wall frame and stucco.However the bank has changed the locks on me multiple times to "protect their asset", which got me wondering, would they also put a new roof on it and repair the rot to protect their asset?

Don't get into a long drawn out - knock down & move the walls type of project as a newbie.  

The main house is completed and as far as labor, I spent $40,000 on just labor and that includes everything from full gut demo to finishes.We are talking about a 4BD, 3BTH two story 2400 ft.² home with a bonus room.This was a full gut job, replaced…12 Windows (new construction)2 sliding doorsTook out all carpet throughout.Took out this ugly 2” thick tile from half of the downstairs portion.Removed popcorn throughout the entire houseTook one wall downA little framing workReplaced entry door 80” x 92”Drywall patchingSmooth drywall work50 recessed lightingAll electrical neededAll plumbing neededNew cement walkway instead of one walk to the front door I created two steps with two lights in each step.Install kitchen cabinets, excluding countertopInstall all three vanities3 bathtubs with one being a modern standalone tub in the masterAll tile work (bathroom wall & floor, kitchen backsplash)Installing of all hardware, faucets, showerheads, etcInstalled 8 single panel doors with hardwareAdding self-leveler after tearing out that thick tileNew LVP flooring throughout the entire house except bathrooms,all baseboards, trimsPainting the entire house, painting all the doors, painting the outside trim.Reframing the outside balconyReframing the fireplace to install new linear modern electrical fireplaceand they took care of the two trash bins.I mean, completely redone.The only thing that was not included in the $40,000 is landscaping, counter top cut and install and of course the ADU which I’m currently working on now.So my question for my fellow investors and contractors did I pay too much?

I have a property under contract and the title company has completed multiple Affidavit of Heirships but have hit a wall.

yeah i believe the instulation is R22 Rock solid, R5 sxp foam on the concrete, and the dry wall is something like 5/8th thick.
