Can I join any credit union in Somerville?
Not always. Every credit union has a "field of membership" — you typically qualify by living or working in a defined area, your employer, or an association you can join. Many community credit unions in Massachusetts accept anyone in the area; others are tied to a specific group. Check each credit union's eligibility before opening a share account (often as little as $5).
Credit union vs bank — which is better in Somerville?
Banks are for-profit and owned by shareholders; credit unions are not-for-profit cooperatives owned by their members, so surplus comes back to members as higher savings rates, lower loan rates and fewer fees. The trade-off is membership eligibility and, sometimes, a smaller branch and ATM network.
