Welcome to INB: Chatham, IL

Chatham was a natural expansion for INB in 2002. A lot of the residents worked in Springfield and were familiar with us, so when Palmer Bank approached us about acquisition, we were all in.  And we were happy all of the employees chose to transition with us, continuing to provide service to their customer base.

While Palmer was located in a strip mall on Route 4, we built a new, highly visible location at Plummer and Route 4.

Owning a home can be the accomplishment of a lifetime. But getting a mortgage loan can bring on a lot of questions and stress. That’s where INB mortgage lenders can be invaluable. They can answer all your questions and help relieve the financial stress with a simple conversation.

To begin, our lenders will help you with a prequalification letter. This is important! We counsel homebuyers to take this step BEFORE beginning a home search. You need to know what you can afford to spend before you go to your first open house. Realtors are interested in talking to serious buyers, and serious buyers have pre-qualification letters from their mortgage lender.

If your financial situation makes it difficult for you to get a mortgage loan, we also provide advice on how to improve your financial situation so that you can eventually qualify. Then when you’re ready to buy, we will be here.
