Any suggestions on where to open a business bank account for my real estate business?
Find a local bank or credit union in Chester since that's your home base. Open a business account with them. Local banks have huge advantages for investors over national banks. By opening a business account now, you pave a path to a future time when you may want to borrow. A bank or credit union you have history with is likely to give you better terms and express more risk when you need it.
Best of luck!
