@Account Closed I manage a property in a high demand area. Not really low income tenants but less desirable (no credit/bad credit, doesn't meet income threshold, or tenant does not want to sign a year long lease).
For me personally, as of now, no real problems. The tenants are getting along well. 2 Guys and a couple. Low turnover. They are paying more collectively for the apartment so it compensates us for 3x times the work - 3 rent checks, 3 leases, etc. It rented very quickly as a rooming house and we got more money.
I know in certain states there are VERY strict requirements on a rooming house. Be careful. In Massachusetts it's limited to 3 and under (technically not a rooming house) and if it's over three (legally a rooming house) it must adhere to many many standards and requires a license.
Normal "tenant issues" could be exasperated because of the closer proximity with other tenants. Instead of driveway issues (your car blocked mine) it would be more petty like he stole my food, they don't split toiletry costs equally, loud music, smoke, bathroom doesn't get cleaned, or someone pees on the seat, etc. (there are ways to lower these problems which I've seen many other rooming houses do - i.e. super cleans all bathrooms or stable tenant pays less but takes on chores).
