Before you spend any money, you just need to price everything out (i.e. cost of homes, moving costs, installation, hook ups such as electrical, water, etc). 

You could sell on lease option or installment sale.

Minimum ADU cost including installation for a tiny one is $110000 and a 800 square foot one is $165000.

I want to know what happens with vacancy rate and what happens if the market declines or new roofs have to be installed or repaving a parking lot or redoing side sewers.In my opinion, this will take someone with experience hours to graph out.It might be a "dyno-mite" deal, it might be more headaches that I want to put up with.

Also, install follow-up. 

Deficiencies, payday loans, credit cards, medical, installment loans.
