There is also a bookkeeper in TX many note investors use (which could be the same one others mentioned). 

Oklahoma as a whole has strong rental demand in many markets, just need to be mindful of the price-to-rent balance, as you mentioned.

Quote from @Jason Burkart: Quote from @Theresa Harris: Whatever you do, I'd keep it in your name if you are the one paying for it, in part for some of the reasons others mentioned (if at some point she goes into a retirement home and needs to use her assets to pay for care).Are you able to pay for her home for 10-20 years? 

You didn't mention the higher Florida insurance costs. 

As mentioned, that is not in your control. 

.#5  Airbnb -  Do NOT mention "airbnb".   

What you would most likely be doing is getting one like Calltools Or Mojo mentioned above, and then push in prospects or manually add them to your Podio account once they have responded with interest.I'm with InvestorFuse, we do have a solo person plan that may be a good fit for you.

Before diving in to offer advice, I'd like to clarify a few things with you, if I may....You mention that you are going to live in the property while you renovate. 

I've worked with several loan servicers, and no matter who you use, it's not fun setting it up, but I've had easier success communicating with OnePoint.They have a login portal to track payments etc, like you mentioned. 

Like others have mentioned, a 30 year loan is better (less pressure).
