as to real estate taxes, escrow deposits and payments are not deductible. you get the deduction when money is taken out of escrow to actually pay the taxes.
points are not de8uctible but must be amortized over the life of the mortgage.
interest charges would also be deductible/
other than those items it's unlikely that any charges are currently deductible. some might add to your basis others are personal expenses which are not deductible or capitalizable.
also, if you refi'd for more than the mortgage balance at that time, interest attributable to the additional borrowing might not be deductible.
