Should I lower my 401k to pay off a mortgage faster?

Lowering retirement contributions to accelerate mortgage payoff forces a trade-off between the guaranteed return of eliminating mortgage debt and the compounding growth of tax-advantaged accounts. This tension leaves homeowners torn between building long-term retirement security and freeing up cash flow to manage intimidating new housing payments.

“Thank you! It’s just that all you hear is “contribute as much as you can to the 401k!!!” And with my strategy being different, I wanted to hear the 2 cents (pun intended) from other people”source ↗

“Give up low rent to buy a house for space or stay crammed and catchup on retirement”source ↗

“It’s looking like 600k to be comfortable. A payment for that is looking like 4400 plus utlities. That scares me”source ↗

“My MO historically has been, when coming into small windfall amounts of money, to just throw it at our mortgage, on the logic that it gets us closer to the day when we don't have a mortgage.”source ↗

“That's coming from a very debt-averse mindset and I am wondering though if that's the best move, though, and I shouldn't just stick those sums into retirement instead.”source ↗
