This corporate office of CTX Mortgage is located in the 155 New Boston business park. CTX is the mortgage division of Dallas-based Centex Home Builders. Centex homeowners can turn to CTX as an in-house mortgage brokerage for their newly built homes, without having to go to a third party brokerage. This branch of CTX is not a walk-in banking facility; rather, it is a corporate call center, and appointments are required.
