5 Steps to Get Your Best Rate
1. Check your credit score first. Lenders offer their lowest rates to borrowers with excellent credit (740+). If your score is lower, you'll see higher rates, but knowing your score helps you shop strategically.
2. Get pre-approved before visiting dealerships. Banks and credit unions will give you a pre-approval letter with your rate locked in. This gives you negotiating power at the dealership and prevents hard inquiries that hurt your credit.
3. Shop at least 3-5 lenders. Boston-area options include Mass Bay Credit Union, Metro Credit Union, Harvard Federal Credit Union, Bank of America, and local banks. Each has different rates for new vs. used vehicles.
4. Choose a shorter loan term. A 48-month loan typically has a lower rate than a 60 or 72-month loan. You'll pay less total interest, even if the monthly payment is higher.
5. Ask about rate discounts. Some lenders offer discounts if you set up automatic payments or maintain a certain account balance with them.

What Affects Your Rate
Lenders look at your credit score, down payment size, loan term, vehicle age, and debt-to-income ratio. A larger down payment (20% or more) usually gets you a better rate. Newer vehicles qualify for lower rates than older ones.
Pro Tip
Getting multiple rate quotes within 14 days typically counts as one inquiry on your credit report. Shop fast to minimize damage to your score. Avoid financing at the dealership unless they match or beat your pre-approval rate.
