Unless agreed to beforehand, all balances must be in the form of a certified check or personal money order.  (Most, but not all, owners will accept personal checks from repeat tenants with a good rental history.)  We mail the balance checks to the owners as soon as you arrive, so all payments must be in a form that can be mailed directly to the owner.    Cash, Travelers Checks, and checks made payable to our office cannot be mailed directly and so they are not acceptable forms of payment. Most credit card brokers will not accept private rental listings.
