I'm 30 and My Lender Wants Me to Cash Out $36,000 in 401(k)s for a Down Payment: But That's Actually a $1.2 Million Mistake

"$36,000, letting it ride from 30 to 65, that would turn into $1.2 million. So this is not a $36,000 decision, it's a $1.2 million decision. -George Kamel, The Ramsey Show, "Debt Robs Your Life of Margin""

"The math is long-run equity compounding. The S&P 500, which most target-date 401(k) funds lean on, has returned roughly 261% over the last ten years through SPY, and 82% over the last five. Stretch that compounding across 35 years between age 30 and 65 and a five-figure balance becomes a seven-figure one. That's the engine Dan would be turning off."

"Start with what leaves the account immediately. A pre-59½ withdrawal from the employer-match portion gets hit with ordinary income tax plus a 10% early-withdrawal penalty. On a roughly $14,000 to $16,000 traditional balance, that clips a quarter to a third of the money before it reaches the closing table. The $22,000 Roth piece is slightly friendlier on contributions, but earnings withdrawn early still face tax and penalty. Kamel noted Dan would also pay penalties and fees."

A 401(k) withdrawal for a first home can be a wealth-destroying decision because it removes money that could compound for decades. Keeping $36,000 invested from age 30 to 65 can grow to about $1.2 million through long-run equity compounding. Cashing out early can trigger ordinary income tax and a 10% early-withdrawal penalty, especially on pre-59½ withdrawals from employer-match amounts. Roth contributions may be treated more favorably, but early withdrawals of earnings can still face tax and penalty. Additional penalties and fees can further reduce the amount available for the down payment. The lost growth and immediate tax costs outweigh the housing benefit in most cases.
