Others will chime in with things I miss, but you CAN deduct any 'points' fee you paid for a lower interest rate (and that includes any 'loan origination fee', or such-like), PMI payment(s), property taxes.
You deduct interest on the mortgage not taxes but you claim the taxes as well and you can also claim if you reimbursed the seller for taxes they paid but you cant claim your down payment or attorney fees.
