Before you become an Airbnb host, calculate whether the additional effort is worth the mone, compared to what you could earn if you rented out the same space on a long-term lease.
Your Airbnb pricing should have nothing to do with what you could charge for a long-term rental.Don'tt even price your nightly rates based on other nearby Airbnbs!
Buy used furniture, and make sure it's in good condition. Craigslist, Freecycle, garage sales, Goodwill, the Facebook Marketplace, and used furniture store are optionss.
