Every space here has been through the host model, so the numbers are already known: what a night costs, how many days are offered, and what the holder pays for the rest. Nothing is priced above 125% of what the place costs its holder.
A host holds each of these and has been through the model. There is an address, a rate and a calendar behind every one.
Somebody has modelled a house and is looking for the people to fill it. These are proposals, not places — no address, no lease signed, nothing reviewed. What they have is a number that works and seats still open.
