Small units in single count are expensive development.  

So I have a 4 unit that is under agreement to sell and the inspection report came back with some electrical issues that needed to be addressed.

It would be pretty unlikely I could be found maximally liable for anything beyond $4 million plus my liability on each unit.

The property is a small three unit multifamily. 

To be specific, how is entry to the unit communicated, status of the work order, and payment processed with the contractor?

Soft cost, carry cost, offsite and fees/.2 = 10,000,000 Total Build Cost 40 pads= 250k per pad Cost [250k/$150 per square ft = 1666 sqft per unit] 250k per pad x 20% = 50k for land ready to build. 

Live in one unit and update it while you rent the other unit, then once that is vacant, move into that one and repeat.With renos, don't go overboard especially if it is a rental. 

But I would contact the owner of the park (assuming you're not buying the unit from them) and ask them. 

Our goal is to help tackle this crisis by rehabilitating one unit/block at a time.

I’m particularly focused on multifamily units in nicer neighborhoods and up-and-coming areas of town.
