I don't know the answer to this, but it does seem like a ton of smaller hostels rent when they're getting started because it's just so expensive to buy. Here in the U.S. I've seen a lot of leases that are more like: "10 years with the option of a 5-year extension." And imagine that, if after 15 years you're doing well the owner will want to keep you in there. You're right, you wouldn't want to lease for less than 10 years...too much investment.
