The Venmo Problem: Why Informal Payments May Be Hurting Your Mortgage Application

The notification comes through in seconds. A few taps on your phone, and the money is gone—your mom's electric bill, your kid's school supplies, groceries for a parent on a fixed income, all paid for. It barely registers as a financial decision. That's the point of apps like Venmo and Zelle.

But when you sit down to apply for a mortgage, that money is going to matter. 

How might informal payments hurt your mortgage application? Turns out, they can in several small ways that can add up to headaches if you’re not careful. 

If you’re supporting others, this is for you

Members of the “sandwich generation”—those who are financially supporting not just themselves but their aging parents and growing children—understand the importance of knowing what’s in your bank account. With money flying in every direction, it can be difficult to keep track of what’s actually yours. 

That ease with which money can leave your accounts can have a direct impact on a home loan application. Lenders want a detailed accounting of not just how much money you have, but how much of it is committed to other debt or responsibilities—car payments, credit cards, or the cost of an assisted living home for your parents, for example. 

Informal payments, such as those made through Venmo or Zelle or in cash, won’t be captured easily by your lender. But they will still impact the underwriting process, and your ability to make your payments after you are approved. 

What lenders consider when you apply for a loan

Not all home loan products require an excellent credit score, stable income, and sizable down payment, but having these things gives you more options. One of the more consistent factors that a lender considers is your debt-to-income ratio—namely, how much debt do you have relative to the amount of money you make? 

A standard practice when applying for a loan is calculating your DTI ratio, by tallying up your various payments, loans, and bills, and dividing that by your monthly income on your pay stubs. Once you apply for a loan, your lender will do the same thing. But it will calculate only what you put your name on.

“If you're making your mom's car payment and it's in your name, that hits your credit report and goes straight into your debt-to-income ratio,” says Ashley Harris, director of homebuyer education at Neighbors Bank. “The informal stuff, the cash you're handing to family members, the groceries you're buying for your parents, that's invisible to the system unless it's creating overdrafts or depleting your reserves.”

How Venmo and apps make things complicated

Here’s the thing: Lenders will see that you’re sending out this money to various people in your life. 

“Lenders do not log in to your Venmo or Zelle apps, but they will see transfers in the two months of bank statements you have to send in,” says Travis Erickson, a licensed mortgage broker at Bonelli Financial Group. “They do look for undisclosed debts and large deposits. If you are sending regular money to someone, an underwriter may need to make sure it isn't a personal loan not reporting to credit, child support, or alimony."

In short, you’ll need to be ready to explain where this money is going and why. And if the roles are reversed and you’re using Venmo to receive money to use for your down payment, these apps are not a black box—lenders will want you to prove the source of those funds. 

“Large unverified cash deposits typically can't be used for a mortgage, and underwriters will throw them out,” says Erickson. 

These payments, which can be difficult to keep track of, are also a potential red flag if lenders think you are draining your resources too quickly. 

“Think of it like a gas tank. A lender wants to see that you're not running on empty when you pull out of the driveway. When you're regularly covering someone else's expenses, that eats into what counts toward reserves and can still affect your financial picture in ways that matter during the loan process.”

Don’t put yourself on the hook, either

Sharing the financial load by helping someone with groceries is one thing. But be wary of putting yourself officially on the hook for paying off someone else’s debt. 

“Lenders view voluntary transfers and co-signed debt completely differently because of the legal obligation. If you are co-signed on your mom's car loan, you are legally responsible for it, and it will show up on your credit report. The lender must count that payment against your debt-to-income ratio unless you can provide 12 months of bank statements from the other obligor showing that it has been paid directly from their own account,” says Erickson.

There is a thin, but clear, line between these two types of payments. While both can be a financial burden, only the legally obligated payments will count against you. 

What’s the strategy?

Feeling concerned that a web of payments might doom your mortgage application? Don’t count yourself out right away. 

“I tell people to be honest with your loan officer upfront. Not because we're going to judge you, but because we need to understand your full financial picture to find the right loan structure,” says Harris. “If we only see the credit report version of your life, we might qualify you for a payment that doesn't actually work once you factor in everything else you're covering.”

If your DTI is running high because of caregiving and other costs, consider loan products like FHA loans, which are flexible on DTI ratios. Harris says they can go up to 50% with compensating factors like strong savings or consistent employment. USDA loans with zero down payment and lower monthly payments also free up cash for everything else you need to cover. 

From a budgeting standpoint, if possible, Erickson suggests pausing the transfers for big items, and being thoughtful about your accounting—for example, consider keeping the money you send to family in a separate account, “so your main down payment and earnest money account stays clean and easy to document.”

Helping family or sending money to those you care about doesn't have to hurt your homebuying chances. It just has to be accounted for—honestly, carefully, and preferably before you sit down with a lender.
