Dear Creditnet: My credit scores are in bad shape and I've been researching ways to start rebuilding my credit so I can eventually get an auto loan at a decent interest rate. It turns out that the credit union I use offers a "credit builder loan" that is supposed to help my credit scores. How does a credit builder loan work, and will it actually improve my FICO scores? It kind of seems like a scam to me because the interest rate is pretty high, but I've used this credit union for a long time and have always been happy with their products and customer service. - Justin T. from MA
