My house is a split-level and I rent the downstairs as its own unit for $900/month as it has its own entrance/living room/bedrooms while I live upstairs (and also rent the other bedrooms upstairs).

You would be eliminating all non-house hacking purchasers.I recently had a property that we considered for purchase that was ideally set up for a JADU (there had been a addition that already had a separate entrance, BR, and Ba). 

I've been here a year thus far and watched new businesses and new construction make their entrance. 

It comes down to your money's Entrance and Exit..and the Exit should be accompanied by friends (your money's friends), as in "profit" and/or "cash flow". 

They are all three within 1 block of the projects and one of them is actually the last house at the entrance.

Broken glass, blocked entrances to rooms, clothing, toys and old furniture everywhere.

The basement also has its own walkout entrance on a concrete patio at the back of the house underneath the deck.

It was the appliance in conjunction with an exterior entrance that flagged it.

One shared meeter, two doors already in place to separate two different tenets, both have private entrances.

There also is 1 room up and 1 room down with it's own bath (so total 6 bedrooms and 4 bathrooms). 4 of the rooms have their own exterior entrance.
