<prompt> Human: I just received a property value notice from the county and my appraised taxable value of my house went DOWN 95,000 from last year. I assumed they over estimated the previous year since it was new construction.I received a letter today from Wells Fargo that they are increasing my escrow from 300 to 1,700 per month!Ive already emailed them now to ask if this is in error, but has anyone else experienced this? Seems unsustainable for someone trying to make mortgage payment to be hit out of the blue with a 5X increase.  <response>: Apparently you arent the only one. And after googling your issue, it seems Wells Fargo had to settle a case for doing something similar to what this linked post talked about. Many mortgage violations. See what you can find out about your property taxes and insurance and provide them with proof of your numbers and valuations to see how it compares to their numbers. Start there.
