Hi, @blueslippers, I understand your proposition completely. I’ve hosted in that way for a couple of friends of mine, and it worked out mostly fine. They have a duplex. They live in the upstairs portion, and they wanted to rent out the lower portion on Airbnb, contracting with me to co-host. They initially proposed a percentage split, but after our friendship was strained by differences in operational approaches, I proposed they rent me the space and let me run it. They accepted (there were advantages to us both that way).
So I paid them a flat monthly rent, made all of the hosting decisions, kept all of my own profits, and also ate any losses. Any costs that were associated with infrastructure (e.g. plumbing leaks) were paid by them, since they were the owners. Any costs associated with supporting guests, such as bedding and other supplies, were paid by me (and I kept or sold them those items when we ended the arrangement).
I didn’t negotiate the monthly rent amount as well as I would have had they not been my close friends, so I didn’t earn enough to keep doing it. But that’s not a problem with the MODEL you propose; that’s a problem with my strength of will when negotiating on my own behalf with people I love.
One poster above suggested listing the property, first, and then advertising for a co-host, and proposing your model in that way. I haven’t advertised for a co-host before, so I don’t know the logistics of making that work. I suggest getting in touch with the hosts’ organizing community in San Francisco (there’s at least one that used to meet regularly), and using word-of-mouth in that community. Also, there’s a hosts listserv for San Francisco, and you could spread the word there.
Your model is a fine one, as long as you recognize that you’ll need to be prepared to accept a rent amount that makes it worth their while to keep doing it, if you want it to work out longer term. The host will be breaking down the arrangement in terms of hours of work and hourly rate, and they won’t be or stay interested if they’re earning peanuts, regardless of the model. But, there are big advantages to a co-host being given the freedom to operate it as they wish (even if there are a few imposed restrictions, such as quiet hours inside the home).
On this point, I suggest thinking through YOUR bottom line (since you live there too) in terms of house rules, restrictions, and other details, and making those clear up front, so the host is fully informed of what limitations you need. I worked these details out with my friends before we started, determining what limits they needed in terms of quiet hours, numbers of guests at one time, access to shared spaces, etc, since my activities would have an impact on them (noise, yard access, people possibly knocking on their door even if it’s against the rules, etc.). That way, I could assess whether I’d be able to find enough guests that met their requirements and mine. If these things aren’t established up front, you could wind up with conflicts later, along the lines of: “I need unfettered access to my kitchen at 7 am to get ready for work, but there are too many Airbnb guests in there on weekends,” and the like.
Hope this helps. Feel free to PM me.
