Bartlett, NH - STR Booked For 40 Nights - Red Flags?

[Bob D.]

We just had a party of guests book our ski house in Bartlett, NH for 40 nights over January and February 2023. I'm pretty skeptical of doing this and will likely cancel the reservation but is there anything I can do to protect myself against something going horribly wrong here? I was thinking of (1) signing a formal short term lease agreement (2) having the renters pay utilities and (3) requiring that the renters obtain "renters insurance" over the course of their stay. Anything else?
