We owe $18,000 on our mortgage, would it be wise if I took $18,000 out of my 401K via my employer to pay it off? We currently have $78K +- in that account.

We also have a 2nd 401K with approx. $11,000 and I have a retirement plan with UPSF (25 years of service) If I do pay the mortgage off, I will definitely increase my contributions to the 401K I have with Old Dominion Freight Line.
