Any "Rule of Thumb" for Air BNB/VRBO income potential?

[Beau M.]

I realize there is a ridiculous amount of criteria that would affect this but just curious if anyone uses any vague/general rule of thumb to quickly evaluate. Before trolling with negative comments I understand the wide variety of criteria but someone came up with the 2%, 50%, 70%, etc.. rules of thumb so wondering if there is any such thing for short-term rentals that I am un-aware of? TIA for any productive input!
