I am about to purchase a property in Miami Beach to do STR, and I'm so excited to start my Airbnb business venture. 

They are a Purchase & Sale Agreement, Title Report, Power of Attorney, Disclosures, Closing Statement, Payoffs and a business card to a good attorney to get you out of the mess you will create if you try doing this on your own.But use somebody, like us, that actually knows what they are doing to learn this.

Even though they are family, I recommend you treat them as business partner in this scenario. 

Previous business partner How did you finance this deal?

Personally I work in the lending business and would love to inform you on my experience based up on what my clients typically go for.

STR is not intrinsically real estate; it is a business that uses real estate.

Do you have his business name by any chance?  

Section 8 is guaranteed income on the first, allowing me to scale my business.

I have been scaling up the STR/MTR business.

You also can take the loss if you have other passive income or if you (or your spouse, if married) work in a real property trade or business and you materially participate in the rental.
