Do you have a mortgage? Yes? Then at some point in your home-owning life, you have received a letter telling you that your mortgage has been sold to another lender. There's certainly nothing unusual about it when this happens, as home loans are sold every day in the United States. It is a very common practice. Typically, the letter tells you that nothing will change for you and – "you do not need to do anything."
WRONG!!! - You should contact the insurance agent that handles your home insurance. 
Here's Why: If your home insurance is part of your escrow then your agent needs to know and needs to change the Mortgagee endorsement on your policy.
Every year your insurance company sends a bill to the company that owns your loan. Your lender sends a check from your escrow account to pay for your Homeowner’s insurance for the next year. If your insurance company does not have the correct lender information the bill will be sent to the wrong company and the bill will not be paid. Believe it or not – that is not the big problem.
Here is the BIG PROBLEM. Your new lender wants to know you have insurance that will pay to replace your home in case of a total loss – they want to know they will get their money! If your new lender does not get a bill or see some form of proof that you have insurance – then the lender will put insurance in place for you. And guess what? The insurance the bank puts in place can cost up to THREE TIMES MORE than what you are paying now and that is just for your house and wouldn't include insurance for all your belongings inside your home.
If this occurs the lender is simply going to pass the high-cost of this other insurance along to the home owner in the form of a much higher mortgage payment on your next statement, which can cause unnecessary panic and confusion.
The lesson – keep your Insurance Agent updated on any change regarding not only your home, but your lender as well. Your agent wants to be up to date and will appreciate the call and it's a simple change that only requires a few moments to complete.
