Reduce your 401k Contribution to the Max company match.

Put the rest money into your money market or other investments. This will increase your down payment and any money that is left over can be used to bolster your emergency fund until you are comfortable enough to move it back to a retirement fund.

You are not allowed to take out as much money from a 401K as you think you can to buy a house. There is no reason to keep putting unmatched money in there if you have other plans that are just as important.
