Any points you or the seller pay to purchase your home loan are deductible for that year. Property taxes and interest are deductible every year.
But while other home-buying costs (closing costs in particular) are not immediately tax-deductible, they can be figured into the adjusted cost basis of your home when you go to sell (any significant home improvements also can be calculated into your basis). These fees would include title insurance, loan-application fee, credit report, appraisal fee, service fee, settlement or closing fees, bank attorney’s fee, attorney’s fee, document preparation fee and recording fees. Points paid when you refinance an existing mortgage must be deducted ratably over the life of the new loan.
