We do charge a pet fee, and it has helped with any extra costs a pet guest has incurred. 

Your PM fees for LTR will be more in the 10-12% range, while for STR it is more in the 25-30% range (and don't forget about GET/TAT). 

Now if you add a guru in to consult for you at a monthly fee, you just made the situation much worse. 

Quote from @Juan Ruben Cortez: I believe the funding fee is 0.5% of the remaining loan balance, plus maybe another $500 - $1,000 in lender fees. 

My lease has a sublet fee (2 weeks is guest by lease more than 2 weeks in a year is sublet) that is costly enough ($100/night per person which is about what a cheaper hotel is here) that makes sure tenants do not have others move-in without informing us.

Second, as sponsor you want a 1 - 2% annualized return asset management fee AND 20% of the profits after the investors get their money back.  

I used Hostaway for the last year and the they recently snuck in a 1.8% fee for our direct booking site.

You will have to gather more accurate operating costs (vacancy loss, taxes, utilities, insurance, mgmt fees, maintenance, HOA) to best determine potential future performance.

As you get larger, you can typically get better management fees, but you typically won't shift from a flat percent to percent + payroll until you get closer to the 40-ish unit range.

Sometimes you can find a large enough company that you can sub everything out to them and get paid on a commission or flat fee basis, or you can get the property platted and sell it that way.
