A SFH with a separate basement entrance.

Better yet, but harder given the price point, find a duplex or single family home with a finished basement/separate entrance that you could rent out.

That is the sidewalk leading to the back porch entrance, main entrance.

I would also consider either building out a deck like Unit 1 has or ditching it and making sure both front entrances have a small ramp for accessibility, in case some of your tenants are elderly or handicapped.2.

It has three separate entrances so we rent it by floor and it cash flows pretty nicely. 

Turned the apartment above the garage to stand alone with a separate laundry and entrance.

Natural air currents will draw the smoke up the stairs to the next floor, so I recommend placing the smoke detector at the stair entrance, mounted on the wall just below the joists.

The location right on a main entrance road to the Blue Ridge Parkway is perfect for attracting out-of-state travelers.

There is only one entrance, so it's not like I can split the place up and have no contact with the short term tenet.

People would pay a bit more to have their own entrance and not have anyone living upstairs from them.
