[Inked&Preggo due 6-30-09!]

ok, i posted a similar question but with a different header just incase i didnt get any answers.but here is my concern. i pay the rent/morgtage directly to the bank every month. i went to pay today and found out the payment due was raised by $320! Come to find out the landlord did not pay his taxes on the house, so the bank payed them, and raised the mortgage until it is payed off. The landlord expects me to pay the higher amount until he pays it off! I pretty much refuse to do that. that does not sound fair, nor legal. (and to make situation worse, landlord is father-in-law). so if i just keep paying the amount that was due previous to his non-payment of taxes, can they still put the house in foreclosure? and if so, how long does that usually take? because he says he will be paying the taxes by end of summer, which would reduce the payment back down, and he can pay back the bank the amount owed from his lack of paying the taxes in the first place.
