Does anyone else have input on Loftium as a start up?

[Sean Monahan]

Recently I purchased a rental home and after posting was contacted by Loftium.  From what I could research Loftium is a start up that states it will help with a down payment on a house in exchange for the new home owner guaranteeing  Loftium the opportunity to Airbnb a bedroom of yours out for one to three years.  If it rents they collect a majority of the airbnb income and if not it is a loss to them.  I'm interested in getting input as to how this could affect a niche market and legalities of the situation in various states.  Also I'm a little perplexed as I have already purchased the home.

Thank you BP members in advance for your input.
