Credit Unions used to be a great source for low interest loans, perhaps before the 80's. Most modern Credit Unions are nothing other than for profit banks under the moniker of "Credit Union". There may be a few exceptions but the easy qualification and low interest loans are just not what they used to be.
Credit unions are financial co-operatives owned and controlled by their members. They offer savings and great value loans plus they are local, ethical and know what their members want.
Each credit union has a "common bond" which determines who can join it. The common bond may be for people living or working in the same area, people working for the same employer or people who belong to the same association, such as a church or trade union.
