Yes, they do check your credit when you lease a car. You have to have good to excellent credit to qualify for a lease. If you have poor credit you may be better off buying and financing your vehicle than trying to get approved for a lease. Pull your credit report and see what your credit score is before you go applying for a lease.
When you get your report make sure you pull it from all three major credit bureaus (Equifax, Experian and TransUnion), because this is what the lender is going to do. They may look at only one, or at all three sources to determine if you can qualify for a lease. You can get one free report at AnnualCreditReport per year. Review your report to make sure that there isn't anything that has been reported that is inaccurate. To qualify for a lease you want to make sure that you don't have any credit issues at all, or if you do they need to be very minimal. All your accounts must be current and up to date. No late payments. Your history should reflect a consistent, on-time payment history with several long-term accounts. If you have bankruptcies, collection accounts, repossessions or judgments on your history, you are not very likely to get approved for a lease.
A leasing company will also want to know the name of your employer and your income information. With your income the bank will determine your debt-to-income ratios to make sure that you are not over extended. Your gross annual income should be more than enough to cover all of your monthly debts, that are listed on your history report. For an example, if someone owes $ 80,000 per year and their income is only $ 100,000 per year, they will more than likely be declined. Their debt-to-income ratio is too high. Everything you are making payments on, like your mortgage, credit cards, automobiles, personal loans, etc., all show up on your credit report. You can also expect to show at least two years of a verifiable address and employment.
The leasing lender requires excellent credit because of the risk they are taking on the leased vehicle. You will usually pay less on a leased monthly payment than what you would if you purchased the vehicle and financed it. If someone defaults on a lease the bank can lose a lot of money. At the end of the lease you are charged for any over-mileage excess and wear-and-tear on the vehicle. If you don't pay these charges, the lease company will report this to the credit bureaus.
