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

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.

Figure out how much you can afford to spend on a property and how much you can realistically charge for rent.Research properties: Look for properties that have separate entrances for each unit and enough space to comfortably accommodate tenants.

My wife and I are remodeling a 1940s bungalow-style home in St Petersburg, and after several months of interior work, we need design help and drawings of the front exterior for our contractor to gain permits from the city and move forward with the project.The original front entrance of the home was covered with an addition built by previous owners, and we'd like to boost curb appeal and value by adding a driveway, front steps, a new door with sidelights, and an overhang jutting out from the gable with columns. 

We live in the front half and airbnb the private entrance 1 bedroom, 1 bath, living room (hotel suite style) back half that is separated by a door that we deadbolt.

It has so much potential for renting out at least 3 separate entrances.

Or a separate area of house with private entrance/exit?

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

@Jerad GrahamHouse hacking properties should have features like a quadplex with 3-4 bedrooms, flexible layouts, private entrances, and amenities.
