What is the name of your state (only U.S. law)? Maine My mortgage company sent me a letter saying that my escrow account was too low, and I had to pay $794.
When I asked why, they said that my taxes (which are due in March and September) were due early. I said this makes no sense. Does it?
Look at the letter again. Is there any other information? It is quite unusual to get a a letter indicating an increase without any supporting calculations or documents. Did your mortgage company pay out more in taxes and insurance than you paid in escrow? Is the letter from your current mortgage holder or the previous one?
There are laws and rules about escrow accounting and reserves. They differ slightly for mortgage types, but it is legal to hold a cushion equal to 1/6 of your combined tax and insurance amounts.
If you cannot communicate by phone, contact your motgage holder by email or US Mail. They don't know why your taxes or insurance amounts increased or why municipalities change the due dates for tax payments. If these items caused your increase, your insurance agent and your tax collector can answer questions about those costs. Most financial institutions have online access for customers. Look and see if there is an escrow analysis for your account.
Getting a letter demanding payment with no explanation sounds like a possible scam. Did you call the number printed on the letter or did you call the bank number listed on your statements?
