Why Taking on New Debt While Under Contract Can Jeopardize Your Home Purchase

March 24, 20263 min read

Buying a home comes with a lot of moving parts, and one of the biggest mistakes buyers can make after going under contract is taking on new debt.

A lot of people assume that once they are approved and under contract, they are in the clear. That is not always true. In many cases, lenders review your financial profile again before closing. That means the choices you make during those final days and weeks still matter.

One of the most common problems is buying or financing a car before the home purchase is complete.

Why buying a car during escrow can cause problems

When you finance a car, you are adding a new monthly payment and taking on new debt. That changes your debt-to-income ratio, which is one of the key numbers lenders use to determine whether you still qualify for your mortgage.

Even if the car payment feels manageable to you personally, your lender is looking at the full picture on paper. A new loan can reduce your borrowing power or affect your approval altogether.

This is also true if you:

  • Open a new credit card

  • Co-sign on a loan

  • Finance furniture or appliances

  • Make large purchases that increase your debt load

The issue is not just whether you can afford it. The issue is whether your mortgage file still fits the lender’s guidelines by the time they do their final review.

Yes, lenders may check again before closing

Many buyers are surprised to learn that lenders often pull credit again before closing. Just because you were pre-approved at the beginning of the process does not mean everything is locked in no matter what happens afterward.

If your credit profile changes, your lender may have to:

  • Recalculate your loan

  • Request more documentation

  • Delay closing

  • Change your approval terms

  • Deny the loan in more serious situations

That is why real estate agents and lenders are constantly telling buyers the same thing: do not make major financial changes while you are under contract.

What buyers should avoid before closing

Once you are under contract, the goal is stability. Keep everything as consistent as possible until the transaction is complete.

That usually means:

  • Do not buy a car

  • Do not open or close credit cards

  • Do not finance furniture, boats, or equipment

  • Do not move large amounts of money without talking to your lender

  • Do not make unusually large purchases on credit

  • Do not quit or change jobs without discussing it first

Even a decision that seems unrelated to your home purchase can create extra scrutiny from underwriting.

What you should do instead

If you are thinking about making any financial move before closing, talk to your lender first. Do not guess. Do not assume it will be fine. A quick conversation can save you from a major issue later.

The safest plan is to wait until after closing day. Once you have officially signed, funded, and received the keys, then you can move forward with bigger purchases.

Final thought

Buying a home is all about getting to the closing table without unnecessary complications. A new car might be exciting, but it is not worth putting your home purchase at risk.

If you are under contract, keep your finances steady, follow your lender’s guidance, and wait until after closing to make any major purchases.

That kind of discipline can make the difference between a smooth closing and a stressful last-minute problem.
