Investing into Turnkey Rentals should you do it?

[Alicia Harrington]

Now that I have some time on my hands I'm looking into turn key rentals.  I have one company that I'm looking at, Rent to Retirement.  However, with just one company how do you know if you're making a wise decision?  Are there any other companies out there that I can check into?  Has anyone else done this to increase their cash flow?  I already have some feedback on a previous post in reference to Rent to Retirement.
