I was a financial planner for 17 years in Canada, and now doing real estate in USA... diversifications is diversifying and mitigate the risks...tax strategies are awesome in Real Estate, especially in USA. 

Having cards from all different banks is essential for mitigating the risk of worst case scenarios (i.e...house sits on market or flip is a FLOP).  

In 2009, after the collapse in the housing market and after the banks cut off further funding and called in loans, you were able to buy 1st mortgage debt for .10 cents on the dollar. 2nd mortgage liens were available ...

It can be a little scary doing your first deal alone so finding a partner helps mitigate your risk. 

The lender's incentive is the mortgage is insured and their risk is mitigated.

You want to have happy tenants, so you have a positive outcome and experience, possibly stand a good opportunity to retain this tent, rather than replace them in 12months, mitigate your long term risks now.  

Again, the ability to define and mitigate your market selections or operator choices base don past experiences, is huge, try to define the most painful parts of your experience and seek information to understand how your new defined Turnkey partnership will mitigate these elements and help you to enhance your ROI.Still much to consider....... much luck in your search. 

You of course want your own inspection, and an insurance co. will require a wind mitigation report, and if more than 30 years old, a 4 point inspection (get them done at the same time, by the home inspector).

Sure might be a few more cents but my returns on inspections are through the roof... hahaha sorry for the punIf I am concerned about Radon seek a company that not only tests but installs mitigation systems.Termite inspector, One that does inspections and treatments not one that does repairs.

If I were you I would choose the 1st couple, but with non-refundable quarterly rent in advance to mitigate the risk.
