For the property taxes paid, you will need to use the 2012 Actual amount from your 2013 dues statement. If you financed with DVC they will mail a 1098 showing mortgage interest paid.
You can also get the 2012 Actual Property Tax amount online. On the member website, under "My Membership" click on "My Vacation Points" then click on "Annual Dues". Scroll down and click on "View and Print Statement".
