@Jay ChungI would have a handyman frame out a simple wall, 2x4s, and drywall.Years back, we did something similar in a garage we rented out.

For example I am near old town alexandria and the businesses are 200 year old row homes and there is no place to put ramps to get in establishments and door openings are not wide enough, but that is because they also could never comply. 

Install cameras and exterior lighting on timers, place no trespassing signs, and place items that indicate occupancy - like a BIG dog bowl near the front door, shoes, etc. 

It took me 11 years, 25 properties, and 76 doors just to replace my income.

This is a 'nicer' mobile home, double wide, 1998, shaped / looks more like a 'house', attached garage, on a very beautiful private lot. 

ONLY knock on doors and ONLY within 10 days of the auction. that is when folks are getting a reality check that they must do something.

One of my lots had only a garage on it, which the city wouldn't allow, needed to have an inhabitable structure in addition to it. 

As a result, mid term rentals can do exceptional here and there are quality multi family units in the $250k/door range. 

For example , the rental amount doesn’t depend on number of bathrooms, garage, basement status or property size.

Look for multis with separate entrances in different areas like one door in front for one unit and a door on the side or back for another.
