Find your last escrow analysis, or log in on line and find it. Check the amounts of your homeowners insurance and property taxes, one or both has gone up enough to require that increase in your escrow.

They should be mailing that to you and it's a good idea to look at those amounts every year. My mortgages always gave me an option to pay the amount needed to keep the escrow account above its minimum, if I wanted my monthly payment to stay the same.
