Generally there are multiple units for each "zone" if you will when I've seen them installed.Regarding your problem at hand, I personally would simply adjust your plan to move and make your initial plan to get the current issues resolved, while costly now, in the long run holding onto the unit will likely pay off. 

This might give a one-time (non-scalable) boost to cash flow, offer multiple value-add options, and allow the house-hacker peace of mind, via the assumed mortgage, in long-term breakeven or positive cash flow in the event that the value-add plans end up not being executed, and/or the person has to move out, and rent by the room or STR become unavailable for some reason at a future date.

I really like having multiple opportunities to make income from 1 property, including a worst scenario of converting all the units to LTR. 

We fund multiple private loans each much and they are run through title/closing exactly the same.
