Then i cam upon one that looked vacant.

You likely will need a Fl CAM license, in order to get paid to manage a COA.  

I have had everything from REALLY bad credit to no citizenship/documentation to sex offender......It really isn't any of their concern in my opinion.

As a landlord with partners, we have a written policy for no felony convictions for the last 10 years and no sex offenders period.

Does anyone have recommendations on how to deal with NNN or CAM expenses?  

The unit includes a balcony and an in unit washer / dryer.Assumed Value After Capitol Improvements: $125,000Percent Down: 25% (Currently What My Lender Is Requesting) $31,250Interest Rate: 3.5%Rental Term: 30 YearsBuying Costs: 1%Rental Rate: $1,500 ($750 Per Renter) - Includes Garage Parking, Washer / Dryer In UnitCap Rate: 14.40%Vacancy: 8% AnnuallyRent Increases: 2% AnnuallyProperty Management: 6% (I plan to do most of the property management)Maintenance: 1%Move In / Move Out Costs: $2,000 (This is per vacancy change)Mortgage Payment: $979 / MonthHOA: $317 (Includes - CAM, Lawn Care, Master Insurance Policy {does this mean I don't need additional insurance?}

I understand that the Fair Housing Act only limits landlord discrimination based on race, color, national origin, religion, sex, familial status or handicap.

I’m thinking making sure someone isn’t now a registered sex offender or arrested for domestic violence would count.

That usually runs another $1,000 or so.I make each occupant complete a screening so I know there aren't any sex offenders or dangerous people living in the unit.

Cam some please help me understand better or point me in the right direction with books and recommendations?
