My target retirement date fund as returned 19.8% so far this year, 8.1% over the past 5 years, and 7.7% over the past 10 years. Yes, it will go down that's a huge chunk to take out of the market to pay off a house even without paying a penalty. You said it's all employer match (which doesn't matter) you must have a great job. Keep contributing and throw extra cash at the mortgage when you can.
I recently read the majority of gains happen in only a few days time. If you miss the top 10 days of a DECADE it cuts your return potential by 32%.
