Rental lease agreement for AirBNB is that common?

[Joe Splitrock]

My family is going on vacation this summer and rented through AirBNB. We are staying six days. After booking, the owner sent us a 5 page lease agreement for their property. Probably a more detailed lease than half the landlords out there use for their full time rentals. I have used short term rental services some in the past, but never had someone send me a lease. It honestly made me mad. The place is over $250 a night, 50% cancellation, so it already pretty pro-owner. It is making me rethink STR. I can stay at a hotel and cancel up to 24 hours in advance without signing a contract.

Anyone operating STR use leases? Is that common? Anything I should be worried about?
