Short term/Airbnb rentals -- how to estimate rental income?

[Lisa Irimata]

I'm looking at purchasing a property as a short term/vacation/Airbnb type rental. This property is very close to a spring training stadium, good proximity to a state university, and also near some larger shopping districts so I think it has good potential as a short term/vacation rental. My question is, when purchasing a property specifically for short term rentals how did you estimate rental income? My biggest fear with short term rentals is the cash flow instability. Worst case I could rent this place out as LTR and still have some modest cash flow but it wouldn't be great and am mostly interested in a STR scenario.

Any insights on best strategies for estimating what your rental income would be? Apologies if this has been asked before, happy to be redirected to a previous post!
