Petra, most hosts will not rent for any longer than 28 nights. After either 4 weeks or one month (depending on the jurisdiction's interpretation) tenancy rights change and the guest can be very much harder to evict. And you can bet if a guest contemplates taking this sort of action they will be thoroughly versed with the law and where they stand.....they will know all the legal loopholes, and the situation is complicated by the fact that your rental property is not a shared space.....it is an entire property.
I even heard of one situation seven months ago where, in addition to refusing to leave, the guest of a 5 week reservation (while his own property, which was experiencing delays, was being built) after the 5 weeks demanded the listing owner reduce his weekly rent until his property was complete and he could move out, from $1,200 pr week, (the listing price of $170 pr night) to $300 pr week ($43 pr night) because he was no longer a short term guest! He claimed he was not a squatter, was continuing to pay rent to the host who had previously been accepting it and was now classified as a long term tenant and involved the Residential Tenancy Tribunal on the grounds that, as there was no lease to cover his situation, $300 pr week was an acceptable long term rental amount for the standard of property the landlord was entitled to charge on an LTR basis. It took almost 2 months of legal tomfoolery for that to get thrown out.
Even if Airbnb did claim any level of host support, that would end at the termination of the paid reservation, and the host would be on his own from that point! Airbnb do not get involved in any issues outside of their terms of service.
I would be reticent to accept a reservation for any longer than 28 nights and if the guest wants to stay for longer than that I would ask the guest to create another reservation. And even that could be challenged if there was not at least a one night break between reservations.
If it's a hypothetical situation Petra.....keep it hypothetical!
