I'm a local real estate broker, investor, and manager (100+ rentals, mostly Airbnb/STR and multifamily).House hacking is a tried-and-true method and in Sacramento you can produce some meaningful income while enjoying the appreciation and tax benefits of owning real estate.

I currently pay a premium price for my turnovers for a local cleaning company that specializes in STRs.
