The other option is to convert one room into a rental with its own side entrance, kitchenette, washer/dryer, full bath ad street parking.

If you are looking at a fenced in with security pad entrance and have some vacant land inside, you might rent space for RV's, boats, trailers, etc.

it has a separate entrance and likely cashflow if rented as a separate unit.  

Thanks Leah, I’ll go ahead and add the minor decor in the entrance.

I have a pending sale on a 3 bedroom 1 bath craftsman single family home built in 1912, it has a non-permitted but livable basement with it's own full bath, sink & separate outside entrance.

(Long story short...it was her mom’s home and she used the majority of the equity to pay for assisted living until her passing.)Quick Stats:-2 BR and 1 BA on each of two floors-Zoned as duplex with separate entrances, but bottom floor needs a kitchen-Everything it needs to be “move-in” ready is purely cosmetic, i.e., flooring, paint, landscaping, etc.As stated in the report (link above), here are some interesting factoids:1.  

If you can't find one, look at homes with separate entrances.

If ANY party of ANY transaction sounds shady, especially your first, it's likely not worth the anxiety and lack of sleep due to your entrance into such transactions. 

No matter how long (Or short) a tenant stays there, whether the apartment was rehabilitated just 4 years ago, 11 years ago or almost never touched, the bathroom ceiling in all these apartments share the same look like this one here: Dammam Iskan appartement 22.11.28 - BathroomsThe apartments here are identical, they have 3 bedrooms, 3 bathrooms, 2 living rooms and 1 dining room separated with accordion from the 2 living rooms, two small stockrooms, 1 kitchen and 1 entrance, somehow these numbers are below the average.

The second floor is a 1600 sq. ft. apartment with a separate entrance outside and separated utilities already. it currently is 2 bed/1 bath.Each the units needs about 20k in renovations to be fully operational.
