I've had Chase for 20+ years on our home with a fixed mortgage, and our mortgage payment has gone up about 600 dollars in the last 6-8 months, and it's due to Illinois property taxes, and USAA homeowners insurance going up. So difference all going into escrow. Can you check check your insurance company to see if they'd had a price increase, or if any discounts you had rolled off and they didn't let you know?
