A 640 credit score is considered poor to fair, depending on the lender

A 640 credit score sits in the range that most lenders classify as "poor" or "fair" — the exact label varies by institution. It is above the lowest tier (typically 300–579) but below the "good" range that most lenders prefer (usually 670 and up). At 640, you will face higher interest rates, larger down payments, and stricter terms than someone with a score above 700. Some lenders will work with you; others will not.

What matters most is what you are trying to do. A 640 score affects mortgage approval, rental housing, credit cards, auto loans, and even some job applications differently. The specific impact also depends on which credit bureau's score is being used (Equifax, Experian, or TransUnion can report different numbers), and whether the lender is looking at your FICO score or a newer model like VantageScore.

Key Takeaways

  • A 640 credit score is below the "good" threshold most lenders prefer, so you will likely pay higher interest rates and face stricter borrowing terms.
  • Mortgage lenders typically require a score of 620 or higher for conventional loans, but 640 puts you at the edge and usually means a higher down payment and rate.
  • Renting an apartment with a 640 score is possible but landlords may ask for a larger security deposit, a co-signer, or proof of income.
  • Credit card issuers offering cards to people with 640 scores usually charge higher annual percentage rates (APRs) and lower credit limits.
  • Improving your score by paying bills on time and reducing debt balances can move you into the "good" range within months to a year.

How mortgage lenders view a 640 score

Most conventional mortgage lenders require a minimum credit score of 620, so a 640 does not disqualify you. However, it puts you at the lower end of their acceptable range. Lenders typically offer their best rates and terms to borrowers with scores of 740 or higher. At 640, expect to pay 0.5 to 1.5 percentage points more in interest than a borrower with a 740 score — a difference that costs tens of thousands of dollars over the life of a 30-year loan.

You will also likely need a larger down payment. Conventional loans at 640 often require 10 to 15 percent down instead of the 3 to 5 percent that higher-score borrowers can put down. Some lenders may require mortgage insurance even with a 10 percent down payment. FHA loans (backed by the Federal Housing Administration) are more flexible with credit scores and may accept 640 or even lower, but they carry their own insurance costs and restrictions on the property type.

Renting with a 640 credit score

Landlords are not required to use credit scores the same way lenders are, and many do not check credit at all. Those who do run a tenant screening report that includes credit history, eviction records, and criminal background. A 640 score alone will not automatically disqualify you from renting, but it may trigger additional requirements.

Common responses from landlords who see a 640 score include asking for a larger security deposit (sometimes double the usual amount), requiring a co-signer with better credit, or requesting proof of income showing you earn at least 30 times the monthly rent. Some landlords will also ask for references from previous landlords or employers. If you have an explanation for the lower score — a medical debt, a temporary job loss, or a single missed payment years ago — providing that context in writing can help.

Credit cards and other unsecured borrowing

Credit card issuers do offer cards to people with 640 scores, but the terms are less favorable. You will typically see APRs (annual percentage rates) in the 18 to 29 percent range, compared to 12 to 18 percent for borrowers with scores above 700. Credit limits are usually lower — often $500 to $2,000 — and annual fees are more common.

Secured credit cards are another option at 640. These require a cash deposit that becomes your credit limit, and they report to the credit bureaus just like regular cards. If you use a secured card responsibly for 6 to 12 months, many issuers will convert it to an unsecured card with a higher limit and better terms. This is a concrete way to improve your score while still accessing credit.

Auto loans at 640

Auto lenders are often more willing to work with lower credit scores than mortgage lenders, but 640 still means higher rates. Depending on the lender and the loan term, you might see APRs between 8 and 15 percent, compared to 4 to 7 percent for borrowers with scores above 700. Credit unions sometimes offer better rates than banks or dealerships, even for lower scores, so it is worth checking if you belong to one.

The age and mileage of the vehicle also matter. Lenders are more cautious about financing older used cars to borrowers with lower scores, so you may be limited to newer vehicles or have to put down a larger down payment. Buying a car you can afford to pay cash for, or waiting to build your score before purchasing, can save you thousands in interest.

What caused your 640 score and how to improve it

Credit scores are built from five main factors: payment history (35 percent of your score), amounts owed (30 percent), length of credit history (15 percent), credit mix (10 percent), and new credit inquiries (10 percent). A 640 score usually means one or more of these is dragging you down — most commonly late or missed payments, high credit card balances, or a short credit history.

The fastest way to improve is to bring any overdue accounts current and then focus on paying down credit card balances. Paying your bills on time for the next 6 to 12 months will move your score noticeably. Disputing errors on your credit report (you can request a free report from each bureau at annualcreditreport.com) can also help if inaccurate information is lowering your score. Avoid opening new credit accounts while you are rebuilding, as each new inquiry temporarily lowers your score.

Frequently Asked Questions

Will I be denied for a mortgage with a 640 score?

No. Most conventional lenders accept 620 or higher, so 640 qualifies you. You will face higher rates and may need a larger down payment, but denial is not automatic. FHA loans are even more flexible. Shop with multiple lenders, as their standards vary.

Can I get a credit card with a 640 score?

Yes. Many issuers offer cards to people with 640 scores, though rates and limits will be less favorable than for higher scores. Secured cards are a reliable option if unsecured offers are limited.

How long does it take to move from 640 to 700?

It depends on what is holding your score down. If you have recent late payments, expect 6 to 12 months of on-time payments to see meaningful improvement. If high credit card balances are the issue, paying them down can move your score within 2 to 3 months.

Do all lenders use the same credit score?

No. Different bureaus (Equifax, Experian, TransUnion) may report different scores, and lenders use different scoring models. A mortgage lender might use FICO 5, while an auto lender uses FICO 8. Your score can vary by 20 to 50 points depending on which one is pulled.

Should I pay off old debt to improve my 640 score?

Paying off current debt (credit cards, recent loans) helps more than paying old debt. Paying an old collection account can sometimes lower your score temporarily because it updates the account status. Focus on current bills and high-balance cards first.
