A SFR with a detached garage big enough to convert, and alley access for an ADU in the back with separate entrance. 

Those steps did not correct the behavior or issue, so next I discontinued her private entrance for maintenance issues and forced her and all her BS through the main entrance, covered by very obvious cameras.

The really hungry ones are often hanging out at the courthouse entrance handing out fliers.  

I live in the attached ADU above the garage, which has a private entrance.

I personally worked with one and that was an easy entrance into out of state investing and setting up your team.

There are still some good multi-families in Tacoma, and plenty of properties where you could add a MIL / ADU by finishing out a basement with its own entrance.

YouTube that is.I was watching videos on real estate investing and this came up.On the other end of the real estate spectrum I have wasted too much time watching a prankster call landlords about issues like turning his living room into a swimming pool with a big liner and digging a basement from a ground-based apartment where he refused to allow the landlord entrance because it technically wasn't part of the apartment complex and was his.

You're looking for the "spread" between entrance and exit of your cash. 

I am currently shopping around for a Camara Security system for my 10unit apartment complex, located in Grandview, MO.I am wanting to be able to monitor all exterior corners along with entrances and common areas in the interior - it would be about a total of 15 camaras. 

Touching up the front door and mailbox is cheap and easy way to make the entrance clean.
