Did you already take money out of your 401k? Please be aware that taking an early withdrawal from a 401k to buy a house is NOT an exception to the early withdrawal penalty of 10%. There is an exception to that penalty with a traditional IRA, but NOT for a 401k. So if you take money out of your 401k to purchase a house, you will pay a 10% early withdrawal penalty plus ordinary income tax on the distribution, based on your tax bracket.
