Your 401(k) could soon double as a house down payment. The Trump administration has floated a proposal to let investors tap retirement savings for home purchases, building on existing rules that allow borrowing up to $50K or 50% of vested balances. Even without full details, the idea highlights a sharp tradeoff between unlocking short-term housing cash and protecting long-term retirement security.

• The upside: You get fast access to cash from your 401(k) with no credit check, no credit score impact, and no lender involved, while the interest you repay flows back into your own retirement account instead of a bank.
• The downside: You pull money out of the market and lose compound growth, repayment is forced through payroll (about $833/month on $50K), and quitting your job can trigger taxes plus a 10% penalty if you’re under 59½.

The retirement sacrifice: Borrowed retirement dollars lose decades of compound growth that can’t be fully recovered even after repayment, especially if contributions are paused during the loan. Marketed as a shortcut for homebuyers squeezed by high prices, planners warn that 401(k) loans trade future security for present ownership and should be a last resort after safer options are exhausted. It works today, but tomorrow sends the bill.
