Thinking About Tapping Your 401(k) for a Down Payment? Run These Numbers First.

Lately, headlines have floated an eye-catching idea about tapping into your 401(k) to cover a down payment on a home.

If you’ve been saving and watching prices climb, that balance starts to look like an answer. It’s your money. It’s right there. Why not use it?

It’s a fair question, and the answer isn’t automatically no. But the real cost is higher than most people expect, and one widely repeated piece of advice about 401(k)s is flatly wrong. Here’s what to know before you touch it.

First, the myth worth clearing up

You’ve likely heard that first-time buyers can withdraw $10,000 penalty-free from retirement savings. That’s true — but it applies to IRAs, not 401(k)s.

There is no first-time homebuyer exception in a 401(k) plan. The IRS rules on hardship distributions spell out what does qualify. None. If you’re under 59½ and you pull money from a 401(k) for a down payment, the 10% early withdrawal penalty applies whether or not it’s your first house.

People conflate these constantly, and the mistake is expensive. If you have both accounts, that distinction alone may change which one you touch.

Option one: the hardship withdrawal, and what it actually costs

Buying a principal residence can qualify as a hardship distribution under IRS guidelines. Note the “can” — your employer’s plan decides whether it permits hardship withdrawals at all and whether a home purchase meets its definition. Some plans exclude home purchases entirely. Check before you build a plan around it.

If it is allowed, here’s the arithmetic for a New Jersey buyer taking $30,000 in the 22% federal bracket:

Withdrawal	$30,000
10% early withdrawal penalty	−$3,000
Federal income tax (22%)	−$6,600
New Jersey income tax (est. 5.525%)	−$1,658
What actually reaches your closing	$18,742

You keep roughly 62 cents on the dollar. Put another way: to net $30,000 for a down payment, you’d need to withdraw about $48,000.

And that’s only the immediate cost. That $30,000, left alone for thirty years at a 7% return, would have grown to roughly $228,000. So the withdrawal isn’t costing you $11,258. It’s costing you the cash plus a couple hundred thousand dollars of retirement.

Option two: the 401(k) loan

Generally the better of the two, if you’re going to do this at all. You can typically borrow up to 50% of your vested balance, capped at $50,000, repaid through payroll deduction over five years — often longer when it’s for a primary residence.

No taxes, no penalty, and the interest goes to you rather than a bank. That’s genuinely different from a withdrawal.

The risks are real, though:

• Job loss triggers the whole balance. If you leave your employer before the loan is repaid — your choice or theirs — most plans require full repayment within 60 to 90 days. Miss that and the outstanding balance becomes a taxable distribution with the 10% penalty attached. This is the risk people underweight most.
• Contributions often stop. Many plans suspend your ability to contribute while you’re repaying, which means the employer match stops too. That’s free money you’re declining for five years.
• It reduces your take-home pay, which affects what you can comfortably carry on the house you’re buying.
• The interest is paid with after-tax dollars and taxed again at withdrawal.

What underwriting will want

Worth knowing before it surprises you at the worst possible moment: lenders verify the source of down payment funds. A large deposit from a 401(k) loan or withdrawal must be documented with a plan statement showing the distribution. An undocumented deposit triggers additional sourcing requirements and can delay a closing by a week or two.

Tell your loan officer up front where the money is coming from. This is not a detail to spring on them in week three.

Better places to look first

A Roth IRA, if you have one. This is the most favorable account for this purpose by a wide margin. Contributions — the money you originally put in — can be withdrawn at any age, tax-free and penalty-free, for any reason at all. On top of that, first-time buyers can take up to $10,000 in earnings penalty-free, provided the account has been open five years.

A traditional IRA. The $10,000 first-time buyer exception waives the penalty, though you still owe income tax on the withdrawal. Better than a 401(k) hardship withdrawal, worse than a Roth.

A smaller down payment. This is the option people skip. Conventional loans start at 3% down, FHA at 3.5%, and VA requires nothing down for eligible veterans. Yes, you’ll pay mortgage insurance — but PMI is cancellable at 80% loan-to-value, and it’s temporary in a way that a drained retirement account isn’t.

New Jersey down payment assistance. The state housing agency runs programs for first-time buyers that are worth checking before you touch retirement money. Eligibility varies by income and county.

When tapping it might actually make sense

I don’t think the answer is always no. A 401(k) loan can be defensible when your job is genuinely stable, you’re buying a home you’ll hold long enough for the math to work, the loan closes a modest gap rather than funding the entire down payment, and you’ve already exhausted Roth contributions and assistance programs.

What rarely makes sense is a hardship withdrawal from a 401(k) to fund a full down payment while you’re young. That’s the version that costs the most and returns the least.

The bottom line

Your 401(k) is not an emergency fund with a house-shaped exception. It’s the most tax-advantaged money you own, and pulling it early is one of the few financial mistakes that’s genuinely hard to undo.

If the gap between what you’ve saved and what you need is small, there are cheaper ways to close it. If the gap is large, that’s information — it may mean the price range is wrong rather than the savings.

Before deciding, get an actual quote at 3%, 5%, and 10% down on the range you’re shopping, and talk to a tax professional about what a withdrawal would cost in your specific bracket. If the goal is reaching 20%, it is worth reading whether 20% down is actually worth it first. Those two conversations take about a week and will tell you more than any general rule.
