Mortgage rate reset and 401(k) withdrawals: A costly combination

The timing of this decision is influenced by current market conditions, with the 10-year Treasury yield hovering near 4.8%.

If the homeowner, filing jointly with a taxable income of $105,000, withdraws $100,000 from his 401(k), his taxable income rises to $205,000. This places the withdrawal amount in the 22% tax bracket, resulting in $22,000 in federal income tax. Additionally, a 10% early withdrawal penalty levied by the IRS adds another $10,000, leaving him with approximately $68,000.

The penalty isn’t automatically waived at age 55. It’s waived for employer-sponsored plans only if the individual separated from service in or after the year they turned 55. Since this homeowner left his previous employer at age 53, the penalty applies in full. Rolling the funds into an IRA would eliminate this penalty.

Currently, the homeowner owes $320,000 on his mortgage with 23 years remaining, resulting in a monthly payment of about $1,566 at the 2.75% rate. If the mortgage resets to 6.75%, the payment would increase to roughly $2,286, a difference of $720 per month. Paying down the principal could lower this increase, depending on the loan’s terms.

Withdrawing $100,000 and paying down the mortgage would reduce the principal to $252,000. If the loan is re-amortized at 6.75% over 23 years, the monthly payment would fall to approximately $1,800, saving $486 compared to the reset without the paydown. Refinancing is an alternative, but would incur new closing costs and a new loan term.

That $100,000, if left invested, could have grown to approximately $197,000 by age 65. Converting it to $68,000 in home equity means sacrificing potential investment gains and limiting access to funds without selling or borrowing.

Experts caution that this trade-off is significant, especially considering that Americans aged 55 to 69 already hold a substantial portion of the nation’s real estate wealth. Redirecting net worth into a home reduces available funds for unexpected expenses.

Before making such a decision, homeowners should carefully review their mortgage reset terms, understand the tax implications of early withdrawals, and explore alternative options like paying the increased monthly payment from other sources or recasting the loan with taxable savings.

Individuals considering this strategy should also verify their separation date from their former employer to determine eligibility for the early withdrawal penalty waiver.
