First have a good renter agreement to cover you and your guest. Post your points as required by board rules. Get 100% of your money within 10 days of your guest receving the Disney confirmation you get and mail to them. Biggest mistake is 50% now and balance within 45 or 30 days. Disney has to many rules that you could get caught in if guest cancel and you have to rerent points. It's a trust thing but both ways, you are on the short end of that trust.I have rented since 2004 and always get paid in full, if that is not ok with renter I understand and respect and move on to next renter.
