Anecdotally, I've heard that local Facebook marketplace groups are an increasingly successful channel.

I'm a big fan of the booking sites, and we've been incredibly successful with our homes which are listed on multiple sites but 90% of the bookings come from Airbnb. 

Many of the most successful spirit-salespeople have used this method as it works well when done right.Get some funky looking person, even a starving actor for $50 and free food at the event, to be the 'property manager' and say strange, funny phrases to the reporters.  

Sounds like your team is well-established at this point and the value you find on BP will elevate you to greater success! 

I had a lot of success recently with FB marketplace and social media for my last 4 vacancies.

Most of my success on that one property was getting lucky enough to meet the right people.

First, you need to surround yourself with others who are already successfully doing what you want to do.

How can I be just as successful at house hacking in a townhouse?

Many people can house hack and are successful. 

I wish you great success
