How accurate is the BP Airbnb calculator

[Keith Davighi]

I know that the calculator is using aridna to do its calculations but is it accurate?  I'm having trouble finding any single family homes that cash flow sufficiently in the Kissimmee/Davenport FL areas just by using the basic monthly expenses.  Or, is 1k per month about what i should be expecting.  This includes 20% Airbnb fees, lodging and property taxes.  I could likely remove the lodging tax since that can be passed onto the renters.

Suggestions?
