As noted above, the answer is generally yes. Another caveat is how you actually finance--the loan needs to be like a mortgage. Through Disney that will always be the case. However if you are buying a resale you may get a loan that is not secured by the property and is just a general unsecured loan that may not qualify for a deduction. Also, you get to deduct the property tax portion of your annual dues (usually in the neighborhood of 20% of your total dues).
