Sorry, there is not a vacation deduction anywhere. And you cannot deduct loan interest except for mortgage interest.
Yes you can. A DVC Membership is considered property ownership. You're property taxes will be listed on your annual dues document. And if you have a loan, you'll receive a 1098 doc showing the mortgage interest you paid for the year. I've been a DVC member since 2001 and all accountants I've used have confirmed this.
Perhaps! In some cases you are allowed to deduct the interest as mortgage interest if this is a timeshare and deduct real estate taxes. More information can be reviewed for your specific situation by selecting the link below.
