Are offset mortgages offered in the US?

[Melissa Rios]

Question for lenders out there:    do you know of any banks or other lenders that offer offset mortgages?  In this scenario, a borrower would have an account with cash that is pledged or locked up in a CD, and the cash in the account offsets and reduces the interest payment of the accompanying mortgage.   Mortgages that are connected to a mortgage offset account are very common in other countries, but unsure if they are offered by any US banks or lenders?    Thanks in advance for any insight you can offer.
