What a credit union pre-approval means and why it matters

A pre-approval from a credit union is a written statement saying the credit union has reviewed your finances and will lend you up to a specific amount for a car purchase. It is not a may provide — the lender can still back out if your situation changes before you buy — but it tells you exactly how much you can spend and what interest rate you will pay.

The pre-approval process takes a few days to a week. During that time, the credit union pulls your credit report, verifies your income, and checks your debt. Once approved, you get a letter or document you can show to a car dealer. The dealer knows the money is real and can move faster. You also avoid the dealer's financing desk, where rates are often higher than what a credit union offers.

Credit unions typically offer lower rates than banks or buy-here-pay-here lots because they are member-owned and do not answer to shareholders. Their rates also vary less by credit score — someone with a 650 score might pay only 1 to 2 percentage points more than someone with a 750 score, whereas a bank might charge 5 to 8 points more.

Key Takeaways

  • A credit union pre-approval tells you the exact loan amount and interest rate before you shop for a car, so you know your budget and can negotiate from strength.
  • The credit union will pull your credit report and verify your income, so have recent pay stubs and tax returns ready to speed up the process.
  • Pre-approval usually takes three to seven business days, and the approval is good for 30 to 60 days — check your letter for the expiration date.
  • You must be a credit union member to get a pre-approval; joining usually takes 10 to 15 minutes and costs nothing or a small one-time fee.
  • Once you find a car, you bring the pre-approval letter to the dealer and tell them you are financing through your credit union, not their lender.

Becoming a credit union member before you explore

You cannot get a pre-approval from a credit union unless you are a member. Membership requirements vary — some credit unions are open to anyone in a geographic area, others require you to work for a specific employer or belong to a specific group, and some let you join if a family member is already a member.

To find a credit union you can join, use the CO-OP Network locator or the Shared Branch locator on the Credit Union National Association website. Search by your zip code or employer. Once you find one, call or visit in person and ask if you are may be able to access. If you are, membership takes about 15 minutes and usually costs nothing — some charge a one-time $5 to $25 membership fee and require a small deposit (often $25) in a savings account.

You do not need to have been a member for any length of time before you explore for a pre-approval. Many credit unions let you explore the same day you join. However, some require you to have an active checking or savings account for at least a few days, so ask when you sign up.

What documents and information you need to gather

The credit union will ask for proof of income, proof of identity, and permission to check your credit. Bring two recent pay stubs (within the last 30 days) if you are employed. If you are self-employed, bring your last two years of tax returns and a recent profit-and-loss statement. If you receive Social Security, disability, or pension income, bring a recent statement showing the monthly amount.

For identity, bring a driver's license or state ID. The credit union will also ask for your Social Security number so they can pull your credit report. You will sign a form giving them permission to do this — it is called a credit authorization form.

Have your current address, phone number, and email ready. If you have moved in the last two years, be prepared to list your previous address. The credit union may also ask about your employment history for the last two years, so know the names and dates of your current and previous jobs.

The pre-approval process process at the credit union

You can explore in person at a branch, over the phone, or online — it depends on the credit union. In-person is fastest because you can hand over documents when ready and answer questions on the spot. Online or phone applications usually take longer because the credit union has to request documents by email or mail.

When you explore, the credit union will ask how much you want to borrow, what the car is for (personal use, business, etc.), and whether you have a trade-in. They will also ask about your monthly debts — car loans, credit cards, student loans, and rent or mortgage. Be honest about these numbers; the credit union will see them on your credit report anyway.

The credit union will then pull your credit report and verify your income by contacting your employer or reviewing your tax returns. This usually takes two to five business days. Some credit unions can give you a conditional pre-approval the same day, pending verification of income — that means you are approved if your income checks out.

How the credit union decides your interest rate

Your interest rate depends on your credit score, the loan term (how many months you will pay), and the age and mileage of the car. A newer car with lower mileage gets a better rate than an older one. A shorter loan term (36 months instead of 72 months) also gets a better rate because the credit union's risk is lower.

Credit unions typically offer rates in ranges. You might see "3.99% to 7.99% APR depending on credit and loan term." Your actual rate falls somewhere in that range based on your credit score and the specifics of your loan. If your score is above 700, you will likely be near the lower end. If it is below 650, you will be near the higher end.

Some credit unions offer rate discounts if you set up automatic payments from a credit union checking account, or if you are a long-time member. Ask about these when you explore — they can save you 0.25% to 0.5% on your rate.

What happens after you get the pre-approval letter

The credit union will give you a letter or document stating the loan amount, interest rate, and expiration date. This is your pre-approval. It is usually good for 30 to 60 days — check the letter. After that date, the pre-approval expires and you will need to reapply if you have not bought a car yet.

Take this letter with you when you shop for cars. Once you find one you want to buy, tell the dealer you are financing through your credit union and provide the dealer with the pre-approval letter. The dealer will contact your credit union to finalize the loan. The credit union will do a final check on your credit and income to make sure nothing has changed, then send the money directly to the dealer.

Do not let the dealer talk you into using their financing instead. Dealer financing is almost always more expensive than credit union financing. If the dealer says they can beat your credit union rate, ask them to put it in writing — most cannot.

What can go wrong between pre-approval and purchase

The credit union can deny the final loan if your situation changes between pre-approval and purchase. Common reasons include a job loss, a new large debt (like a credit card balance), a missed payment, or a significant drop in credit score. If you lose your job or take on new debt, tell the credit union before you buy the car — they may still approve you, or they may lower the amount you can borrow.

The credit union can also deny the loan if the car itself is a problem. If the car is too old (usually more than 10 to 15 years), has too many miles (usually more than 150,000), or is a model the credit union considers high-risk, they may refuse to finance it. Ask the credit union what their age and mileage limits are before you shop, so you do not fall in love with a car you cannot finance.

If the final loan is denied, you have a few options: find a different car that meets the credit union's requirements, increase your down payment so the loan amount is smaller, or ask a co-signer (like a parent) to sign the loan with you. A co-signer with better credit can sometimes get you approved when you would not be on your own.

Frequently Asked Questions

Does a pre-approval hurt my credit score?

A pre-approval does pull your credit report, which causes a small, temporary dip in your score — usually 5 to 10 points. This is called a hard inquiry. The dip goes away after a few months. Multiple pre-approval inquiries in a short time (like within two weeks) usually count as one inquiry, so you can shop around without extra damage.

Can I get pre-approved with bad credit?

Yes. Credit unions work with people who have credit scores below 600. Your rate will be higher than someone with good credit, but you can still get approved. Some credit unions specialize in lending to people with lower scores. If your current credit union turns you down, try another one — approval standards vary.

What if I do not have recent pay stubs?

If you just started a job, bring an offer letter or employment contract showing your salary. If you are self-employed, bring your last two years of tax returns. If you receive unemployment or disability, bring a recent statement. The credit union will work with what you have — they just need proof that money is coming in.

Can I use the pre-approval to buy a used car from a private seller?

Yes. The credit union will send the money to you or directly to the seller, depending on their process. You will still need to handle the title transfer and registration yourself. Some credit unions require a pre-purchase inspection for used cars, so ask before you commit to a private sale.

What if the car costs less than my pre-approval amount?

You can borrow less than the pre-approved amount — you are not required to use the full amount. Just tell the credit union the actual purchase price and they will adjust the loan. You will pay less interest because you are borrowing less money.
