If you sold a qualified home, you can make deductions up until the time you sold your home, which includes mortgage interest, mortgage insurance, points and real estate/property taxes. You should be able to see these on the 1098 from your lender.
You can also deduct:
- Home improvement costs (which are more or less permanent changes to the house and not the same as repairs and maintenance)
- Mortgage interest and/or real estate/property taxes charged at closing (other than that, almost no closing costs are deductible)
