No Numbers or PnL for STR

[Dawn McComish]

I am seeking feedback here.  In the Florida Keys, we have only a 2 cities that allow 7 day rentals, the rest are monthly, with a few scattered condotels.  There are a lot of places, 7 and 30 day rentals that actually make money, but people do not keep records and are unable to provide actual numbers.  I am usually able to obtain a gross total and sometimes actually have it substanitated by rental history, but that is the best I get in most cases.  These properties still have a good rate of return though. What's the best way to go about presenting these to investors without hard numbers and PnL?
