Has the sponsor owned the property and has the operating history to suggest that project revenue/costs/return is accurately projected?  

Is there an easy work around besides having to pay 20-25% of gross revenue to a property management company? 

Unfortunately, these things can and do happen on occasion, and it is the Property Manager's job to mitigate the damages by trying to charge the guest for damages (and many times this is unsuccessful), and get repairs made as quickly as possible to avoid further revenue loss.  

airdna came out with a great article last year, showing the percentages of places with different types of amenities(like hot tubs) and how much revenue they added in comparison to other rentals that didn't have it.

The annual gross revenue is $165,000-$170,000.

For more context, I did look into renting to a travel nurse and with that revenue I would be cash flowing negative $1400/month.

Any advice/insight would be greatly appreciated.Once you are successful at running a STR (and 20 percent for down payment, closing, and startup costs) you can get DSCR funding based on revenue projections.  

We love living here and plan on keeping it as our personal residence for the foreseeable future, but I feel like there is a lot of untapped potential in possible revenue streams.

My businesses combined generate a healthy amount of revenue so I was going to use the business to leverage a loan which I was approved.
