I think your long term hold goal is a great mindset, I would be shooting for that goal of owning a few properties by the time you're 30.As for what to do next, I would recommend a cash out refinance as long as the rent on the mobile home would cover the payment.

Does anyone have recommendations, and if you had personal dealings with them that were positive or negative.Thanks in advance for your help.

I recommend looking within an hour's drive of Orlando where the numbers look better, and there's not as much competition.

If so, any recommendations on which thermostat to go with?

Any recommendations of positive experiences you have had within the last 6 months would be much appreciated.

Can anyone recommend a solid attorney in New York (long Island) to review docs specifically leases??

I also recommend self-managing this property so that you can get that experience.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Would certainly recommend visiting if one is close to you. 

I recommend looking at B neighborhoods up in your local metro.
