Credit unions in South Carolina often offer lower mortgage rates than traditional banks because they're member-owned non-profits. Here's how to qualify for the best rates:

Join a Credit Union
Many South Carolina credit unions have flexible membership requirements. Some are open to anyone who lives, works, or worships in the area.
Compare Multiple Lenders
