The work isn't in the hours, it's in when they happen and how unschedulable they are. A long-term tenant contacts you a few times a year. A nightly guest generates messages before booking, at booking, before arrival, at arrival, during the stay and after checkout, and a meaningful share of those arrive outside business hours because that's when people travel. Response speed also affects ranking and conversion on the platforms, so a slow reply costs bookings, not just goodwill.
Then there's the failure mode. If your unit's dishwasher dies, the tenant is annoyed and you fix it that week. If the cottage's lock battery dies at 11pm with a family standing outside, you have maybe twenty minutes before that becomes a refund, a one-star review, and a permanent drag on the listing's ranking. Same-day turnovers between an 11am checkout and a 3pm check-in leave no slack at all, and the co-host is the one who finds a backup cleaner when the regular one calls in sick.
The pricing piece is the part that's least visible and most valuable. A pricing tool suggests, someone decides, and that means watching local events, competitor rates, gap nights and minimum-stay rules week by week. The gap between an average operator and a good one on the same cottage is real revenue.
As for whether 20% is competed down, look at what's included. Some co-hosts at 20% handle everything including maintenance and permit renewals. Some at 15% handle messages and calendar only and hand the owner every vendor problem. Comparing the percentages without comparing the scope of work tells you almost nothing.
