When a broker or wholesaler contacts me claiming to have access to XYZ number of off market properties a month, that's my cue to run or unsubscribe from their mailing lists.

Most nearby cities are the same.Even in the Denver-adjacent cities that do allow non-owner occupied STRs, they vary widely -- some have caps on STRs, some cap the nights rentable as an STR, some cap the number of vacation rentals one owner can have, etc. etc.This is all to say, first know where you can do Airbnb, then start running numbers.

I noticed the market was shifting, so didn't run to get under contract until day 43 of the identification period.

You should reach out to @Melissa Haworth she can get the actual numbers/rents on STRs in the area to help run your comps.Each building is different, each area is different, it is important to find accurate data to make good decisions.

Once you feel comfortable in running your numbers, figure out a good market that has good population & economic growth and landlord friendly laws.

App=Spart...If you need a tool to run your deal I have created this free tool that you can use btwhttps://real-estate-tools.com/real-estate-deal-calculator/?

Keep running the numbers—sometimes waiting for the right deal is the best move!

Remember you are running a business. 

You need to see how they run things.

Also ask at the store what the run time is on the washer.
