The bottom half has its own entrance and everything to it.

No step showers, no step entrance, extended doorways, etc., etc.

The basement has a private entrance, two bedrooms, full bath, living room, a off-street parking space, and W/D.

Still a good deal, but my question is, why would they ever rent something like that over another similar house that doesn't have someone living downstairs (again - it would be completely separated with separate entrances as well - we would never see each other, but still). 

I am evaluating a SFH that is zoned for a duplex, and already has separate entrance, 2 kitchens, and 2 bathrooms because it is currently used as a student rental.

Entrance:  Properties for Sale = Cost to get inExit Option #1:  Sold Comps = Profit to exitExit #2:  Rental Comps = Profit to stay in

Looking at a 2 fam with RR apartments.Is it legal to just close up the doors that connect the rooms and put in new doors out to the hall so the rooms are no longer connected and each room has its own private entrance?

Introductions aside, I have been figuring out how I want to make my entrance into Real Estate Investing (gotta start somewhere).

Make an offer on a 3 bedroom 1 bath house in a desirable popular neighborhood that has a finished (non-permitted) basement w/ a full bathroom, sink, separate entrance outside & washer/dryer.

@Charles KaoThe building really doesn’t have room for expansion besides value add in raising the low rents, it also does not have a gate/security system which could easily be added (facility is surrounded by units so it only needs a main entrance gate).
