Judging by the photos of available houses for rent, they do a good job of maintaining their interiors, but I would not want to live next door to their dead lawn rentals. 

Keep me in mind if you find something a little larger you’re interested in. 

If it's a larger organization, feel free to inquire about their different staff qualifications.2.

As far as cashflow I would like to see minimum $200 if it were a single family or $100 per door for anything larger and around a 12% cash on cash return.

The more money you spend in the beginning, the larger the number you have set as your break even point, and the longer it takes to reach.

I'd like to buy and hold getting a minimum $250 cash flow per door with a 12% IRR. 

I assume a D neighborhood. also its close to 2%. but anything that rents for under 700ish os going to cost you. paint and doors cost the same for a property that rents for 1200, but atleast you can renovate it every year at higher rents.

Just trying to determine if long term, even though the tenants may pose a larger risk, in the end result with a higher return.

Before you spend your IRA/retirement money, I would suggest you investigate other ways to invest into larger deals.

Example:  I just had a punk move out, trashed my doors!!
