@Alex Hymanson  you should read the book...Storing Up Profits. 

I have three listings, 1. unit with a pool and hot tub, 2. unit with a hot tub, 3. both units together as a 12 sleeper.Gross monthly income (after booking channel fees) for the first unit over a 7 month period was $7309.Gross monthly income for both units over a 14 month period is $11,297 (after booking channel fees) As a long term rental the combined rent would be in the region of $5500.Is it possible to sell the property based on the income generated by the STR business or would the value always be based on bricks and mortar comps? 

Then you can read a more in-depth book like The Book On Rental Property Investing by Brandon Turner or The Unofficial Guide to Real Estate Investing by Spencer Strauss.2.

While podcasts, books, seminars, and websites offer general knowledge, you'll buy a specific property in a specific location, subject to local rules and regulations.

Over the past few months, I’ve been diving into Brandon Turner’s books and bingeing Dave’s BiggerPockets podcast whenever I have the chance.

I'll check out the book.
