Get your taxes done using TurboTax

If you rented a portion of the home you also live in then that is NOT considered a vacation home  so if that is how it was reported that needs to be corrected.   When you rent a portion of the home that portion is not used personally  and the vacation home rules do not apply.    A vacation home is a place where you use the entire home while you are there and rent the entire home when you rent it ... there is no personal use while it is a rental.
