I just paid off paid off one of my timeshares and I have not received any tax forms. Should I have real estate taxes to claim?

For a timeshare, only mortgage interest and property taxes (if paid in 2016) are deductible.

To be deductible the loan must be secured by the property.

 Maintenance and other assessments are not deductible

In the event of an audit you will need to be able to document mortgage interest and property taxes paid in 2016.
