"Can I Use a Custodial Account or a 529 Plan for a Down Payment?"

Two statements come in the mail every quarter besides your checking account. One is the custodial account you opened the year your daughter was born, with your name on it as custodian and hers as the child it was set up for. The other is the 529 plan you have added to every birthday since. You have found a home you like, and the down payment is a little short of where you want it. Both of those balances are looking back at you from the kitchen table.

Sometimes they can help. Luxury Mortgage Corp., one of the lenders I work with, accepts a custodial account for a child or someone else toward your down payment, closing costs and reserves. It counts a 529 savings plan at 60% of its value, and a prepaid tuition plan not at all. Either way, the lender has to document that you can get to the money.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996, NMLS #483943, through C2 Financial Corporation, licensed in fifteen states. This page walks through what that lender's written guideline says, what Fannie Mae, Freddie Mac and FHA say about accounts in someone else's name, and what you will want to sort out before you count on either balance.

Can you use a custodial account for a down payment?

With the right lender, yes. Luxury Mortgage Corp. publishes underwriting guidelines for its Simple Access loans, which are non-QM loans. That means they are written by the lender itself rather than to Fannie Mae, Freddie Mac or FHA rules. You can read more about how that category works in what a non-QM loan is and who it fits.

Section 6.3 of those guidelines, version 9.2, dated July 8, 2026 and revised July 31, 2026, has a short paragraph titled "Custodial Accounts for Children or Others." It reads:

"Custodial accounts for children or others are an acceptable source of funds for down payment, closing costs and reserves. 529 Accounts are acceptable with a copy of the plan showing a savings plan and not a pre-paid tuition plan at 60% of face value. Document the Applicant's ability to access the funds in order to utilize them."

That is one lender's rule, and it applies to that lender's loans. Other lenders may treat these accounts differently, or may not accept them at all. The same guideline also points to the lender's rate sheet for which states the product is offered in, and that list can change. If you are thinking about this route, I will confirm whether it is available for a home in your state before you plan around it.

The guideline sets no percentage for a custodial account. Instead, the underwriter wants proof on paper that you can get to the money and use it for your purchase.

How a 529 plan counts toward a mortgage

A 529 plan is a savings plan built for education costs, and there are two kinds. Investor.gov's introduction to 529 plans describes them this way. A prepaid tuition plan lets you buy credits toward future tuition at participating schools. An education savings plan is an investment account that can pay a wider range of education expenses.

The Luxury Mortgage guideline only accepts the second kind. You will want to give the lender a copy of the plan that shows it is a savings plan, because a prepaid tuition plan is not an acceptable source under that paragraph.

Once the plan qualifies, the lender counts 60% of its face value. So a 529 statement showing $30,000 adds $18,000 to the assets the lender counts for you. The other 40% is still yours. It simply does not show up in the lender's math under this guideline.

If the 529 is helping with reserves, which is the money you have left after closing, 60% of a healthy balance can go a long way. What counts as mortgage reserves walks through how reserves are measured and how to take an inventory of yours.

Fannie Mae, Freddie Mac and FHA on accounts in someone else's name

The asset chapters of Fannie Mae's Selling Guide, Freddie Mac's Seller/Servicer Guide and FHA's Handbook 4000.1 do not have a rule written for custodial accounts or 529 plans by name. The sections on deposits, trusts, gifts and other sources of funds do not mention either account.

Freddie Mac does say who has to own an account. Freddie Mac's Guide Section 5501.3, revised July 1, 2026, says that every account held in a financial institution must be owned by the person on the loan, and that person must have access to the funds. Under that wording, the account needs to be yours, and you need to be able to get to the money.

A 529 savings plan where you are the account owner can fit that description, since you opened it and you control it. A custodial account is a closer call, for the reason in the next section. On a Fannie Mae, Freddie Mac or FHA loan, it is worth a conversation with me before you count on a custodial balance.

Who owns the money in a custodial account?

Many custodial accounts for children are set up under a state law called the Uniform Gifts to Minors Act (UGMA) or the Uniform Transfers to Minors Act (UTMA). In a UGMA or UTMA account, the money belongs to the child. FINRA's Regulatory Notice 20-07 describes money put into one of these accounts as an irrevocable transfer to the child, which means a gift that cannot be taken back. The custodian manages it until the custodianship ends, which is usually when the child reaches an age set by state law.

That is why the lender's guideline focuses on your ability to access the funds rather than simply on the balance. It is also why I would suggest talking with an attorney or a tax professional before you move any custodial money toward your own home. Your state's law sets what a custodian may do with the account, and that question is outside what a mortgage lender decides.

The picture changes when the account was opened for you. FINRA's page on ways to invest for children notes that the assets transfer to the child at the age of majority, which differs by state, and can be used for any purpose. If a grandparent opened a custodial account for you years ago and it has since been turned over to you, that money is in your name now and reads like any other account you own.

Taking money out of a 529 before closing

Some clients decide to withdraw part of a 529 and put it in checking before they apply. Before you do that, the tax side deserves a call to your tax professional.

IRS Publication 970, the IRS guide to tax benefits for education, covers 529 plans. It explains that earnings in a distribution are taxable to the extent the distribution is more than your adjusted qualified education expenses. The publication also explains that a 10% additional tax applies to that taxable amount, with a short list of exceptions. A down payment is not an education expense, so this is a real cost to price out before you make the move. Your tax professional can run the numbers for your own plan.

There is a mortgage side to a withdrawal too. A large deposit into checking shortly before you apply is something an underwriter asks about. The Luxury Mortgage guideline says the underwriter must look into recent large deposits over 10% of the loan amount, and asks for a written explanation of where the money came from. Fannie Mae, Freddie Mac and FHA each have their own version of that rule, covered in which bank deposits an underwriter will ask you to explain. A 529 withdrawal is easy to explain as long as you keep the plan statement that shows it leaving.

Documents to have ready before you apply

The Luxury Mortgage guideline asks for a most recent statement covering at least 30 days as proof of the down payment. It treats asset statements as generally good for 120 days when they are used for closing costs and reserves.

1. Your most recent custodial account or 529 statement. When you're ready, please provide your most recent statement for each account you would like counted, all pages, even if the last page is intentionally left blank.
2. A copy of the 529 plan. For the Luxury Mortgage guideline, the lender needs to see that the plan is an education savings plan rather than a prepaid tuition plan. The plan's own program description or account agreement usually shows that.
3. Something that shows your access to the money. For a custodial account, that is usually the account paperwork naming you as custodian, along with the plan's rules for withdrawals. For a 529, it is the paperwork naming you as the account owner.
4. A paper trail for any money you move. If you move funds into checking, please keep the statement showing the withdrawal from the 529 or custodial account and the statement showing the deposit arriving.

If you would rather skip paper statements altogether, many lenders can read your account data directly, which is covered in linking your bank account for asset verification. For the full list of what a lender asks for on a purchase, the documents you need for a mortgage lays it out in one place.

Common mistakes with custodial and 529 money

Counting the full 529 balance in your budget. Under the Luxury Mortgage guideline, only 60% of a 529 savings plan counts. If you are planning your down payment around the statement balance, you will want to plan around 60% of it instead.

Assuming a prepaid tuition plan counts. The same guideline accepts savings plans only. A prepaid tuition plan does not count toward your down payment, closing costs or reserves under it.

Withdrawing first and asking later. A 529 withdrawal can carry income tax and a 10% additional tax on the earnings under Publication 970. A custodial account is the child's money under state law. Both questions are easier to answer before the money moves than after.

Treating every lender's rule as the same. The 60% figure and the custodial account language come from one lender's written guideline. Fannie Mae, Freddie Mac and FHA do not name these accounts, and another lender's guideline may say something different.

An example, with made-up numbers

Numbers below are made up to show the mechanism. Morgan is buying a home through a Luxury Mortgage Simple Access loan in a state where the product is offered. Morgan is the account owner of a 529 savings plan for a son who is in middle school.

Morgan's 529 savings plan	Amount
Face value on the latest statement	$30,000
Share the guideline counts	60%
Amount counted toward assets	$18,000

Morgan's checking and savings cover the down payment and closing costs. The $18,000 from the 529 goes toward reserves, so the 529 stays where it is and nothing is withdrawn. Morgan provides the 529 statement, all pages, and a copy of the plan showing it is a savings plan. The paperwork naming Morgan as account owner is how Morgan documents the access the guideline asks for.

If Morgan's plan had been a prepaid tuition plan, it would have counted $0 under this guideline, and the reserves would have had to come from somewhere else. Retirement accounts are one place clients look next, and borrowing from your 401(k) for a down payment covers how that works.

Other ways family money can help

If the custodial account or 529 does not fit your loan, family support can still reach your purchase in other ways. A gift from a parent is the most common one, and using a gift from your parents for a down payment covers how it is documented. If your savings are large and your income is harder to document, the Asset Qualifier, which divides savings by 84, is a Luxury Mortgage product that counts your assets as income.

This product is not priced in the Rate & Best Fit tool, so the easiest next step is a phone call. You are welcome to call me at (843) 765-0000. We can look at which of your accounts would count, at what share, on which kind of loan, and whether the Luxury Mortgage product is offered for a home in your state.

Nothing here is a loan approval, a denial, or a commitment to lend, and none of it is tax or legal advice. The Luxury Mortgage guideline quoted above is one lender's own and applies only to its loans. Please check with a tax professional before you withdraw money from a 529 plan, and with an attorney about what your state allows a custodian to do.

Common questions

Can I use my child's custodial account for a down payment?

With some lenders, yes. Luxury Mortgage Corp.'s Simple Access guideline, version 9.2, says custodial accounts for children or others are an acceptable source for the down payment, closing costs and reserves, as long as your ability to access the funds is documented. FINRA describes money put into a UGMA or UTMA custodial account as an irrevocable transfer to the child, so please talk with an attorney or tax professional before you move it.

Does a 529 plan count as an asset for a mortgage?

It can. Under Luxury Mortgage Corp.'s Simple Access guideline, a 529 education savings plan counts at 60% of its face value, with a copy of the plan showing it is a savings plan. A prepaid tuition plan is not accepted under that guideline. Fannie Mae, Freddie Mac and FHA do not have a rule written for 529 plans by name.

Why would a lender count only 60% of a 529 plan?

The guideline states the 60% figure without giving a reason, so I will not guess at one. With that lender, six of every ten dollars in the plan count toward your assets, and the rest of the balance stays yours.

Is there a penalty for using 529 money to buy a home?

IRS Publication 970 says the earnings in a 529 distribution are taxable to the extent the distribution is more than your adjusted qualified education expenses. It also applies a 10% additional tax to the taxable amount, with a few listed exceptions. A home purchase is not an education expense, so please talk with a tax professional before you withdraw.

Do Fannie Mae and FHA allow custodial accounts for a down payment?

Their asset guidelines do not name custodial accounts or 529 plans. Freddie Mac's Guide Section 5501.3 says accounts must be owned by the person on the loan, who must have access to the funds. FINRA notes that a UGMA or UTMA account belongs to the child, so on one of those loans it is a question to raise with me before you count on that balance.
