@Alex8846 Some good advice from @Normen0 there. In a high-demand market like SF, you have plenty of room to be choosy about your guests - certainly no need to lower your price on demand. So I'd flip this around and screen for guests who display some green flags:
- Their request conveys that they've carefully read the listing, and shows a glimmer of enthusiasm for what's special about it
- They don't request anything outside of the parameters of what you offer (group size, price, date availability, check-in time, etc) and require no exceptions to the house rules
- They have complete profiles with verified ID
- They answer any follow-up questions promptly with decent communication skills
- The plans they express for their trip seem compatible with the home, location, and length of stay
I would caution against accepting bookings of more than 28 days, unless current regulations require you to do so. Long-term Airbnb guests in California have been known to use the right-of-tenancy laws to squat homes rent-free after their first month, and it's a very long and costly process to legally evict them. Airbnb won't do anything to help you in that situation, so if you want to do long stays, you'd better use an agency that does credit/background checks and takes an actual deposit (Airbnb doesn't).
