As far as I can tell Airbnb does not yet offer that capability in Hawaii.I met with a few agents and cleaners while on island and their feedback was that it should be cash flowing nicely without any major repairs or upgrades.

I would keep that low interest rate and the cash flow as a nice cushion to enjoy when times get rough.

(I couldn’t find if that was a nice gradual increase or mostly done in 1-2 years.)

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.
