Escrowing for taxes and insurance sounds like an easy task. However, the rules regarding the escrow account are very complex. They are also highly regulated by the Real Estate Settlement Procedures Act. (RESPA)
It sounds like the lender did an annual escrow review, came up with a shortage and is now raising your monthly payment to fully fund your escrow account. (Perhaps they have been collecting too little per month over the last year?) They need to explain this to you in an annual statement. Get a copy of it and see if the disbursements were correct. Make sure the amounts going out agree with your tax and insurance bills.
The good news is that I have never heard of a borrower getting ripped off by a lender via their escrow account. The money that goes into the account pays only your bills and is your money. In fact, they have to pay you the interest the account generates. Also, you should find out if the $65 is a permanent increase or is part of it permanent and part of it temporary.
