I sold my vacation home after it was up for sale for over a year. Can I add utility costs and property taxes paid during the time it wasn’t being used by me to the cost basis of the home?

Capital loss carryover

A capital loss that is not deductible because it exceeds the annual $3,000 capital loss ceiling. A carryover loss may be deducted from capital gains of later years plus up to $3,000 of ordinary income.
