Actually the Homeowners Protection Act passed in the late 1990's clarified this exact PMI (abuse/confusion) issue. It requires lenders to release PMI once LTV is 78% of original purchase price. That is not optional, provided the borrower is current with monthly payments. If the borrower is behind on payments, then the lender must release PMI 30 days past the time borrower becomes current with payments. I think there is also a stipulation that the loan in question must be the one secured for purchase, not a refinance, but I'm not 100% sure about that part. If I were the OP, I'd find someway to come up with the amount needed to hit that 78% and kill that PMI. Another way to think about that $300 monthly premium is that it is interest being paid on the 2?,000 difference between current balance and 78% LTV. A personal loan at your bank or credit union for that needed amount divided by the $300 monthly pmi is likely a less costly path than present situation. Read your mortgage closing documents, I'm sure this is in there somewhere, then don't take any lip from Citi or whoever holds your mortgage.
