The documents may not say specifically "property taxes" but have language saying something like "infringement of their security interest" or the like.
Almost every loan contains a provision that you will pay the property taxes when due and that the failure to pay the property taxes is an “event of default.” This means that if you are delinquent on taxes, your lender could, theoretically, foreclose on your property even if you have been making all of your mortgage payments
and if there is language somewhere can the lender attach the tax reimbursement payment to the monthly PI payments?
Yes. The escrow account as it’s called in many areas, came up.
and refuse to take the monthly PI payment if it is not paid with the PI payment each month until it is paid back.
