I am looking at an off market deal to help a neighbor and make a long term investment.

Term 3-5 years.Can anyone advise me as to terms I should offer (interest rate, points, fees etc) and anything else I should be looking for to make this loan?  

Is it as simple as setting up an llc on zen business or should I hire an attorney? 

I focus on long term appreciation plays. 

Your protection is language in your purchase contract requiring the deed provide you marketable title in fee simple and a professional title search and title insurance to cover you.

Quote from @Chidvi Pemula: I avoid smart devices, particularly on short-term rentals.

Primarily I'm looking to get into fix and flips then move into long term rentals.

There's a lot of research you could do on VRBO/AirBNB/AirDNA to compare similar properties in terms of rates and occupancy, but my experience is that Gulf Shores and Orange Beach are more popular because of the nearby amenities, nightlight, recreation, and other things to do. 

Is everyone on the same page with the long-term goal?
