Escrow payment is the common term referring to the portion of a mortgage payment that is designated to pay for real property taxes and hazard insurance. It is an amount "over and above" the principal and interest portion of a mortgage payment. Since the escrow payment is used to pay taxes and insurance, it is referred to as "T&I", while the mortgage payment consisting of principal and interest is called "P&I". The sum total of all elements is then referred to as "PITI", for "Principal, Interest, Tax, and Insurance". Some mortgage companies require customers to maintain an escrow account that pays the property taxes and hazard insurance. Others offer it as an option for customers. Some types of loans, most notably Federal Housing Administration (FHA) loans, require the lender to maintain an escrow account for the life of the loan.
