I had a Roth 401k at a previous employer which I recently (few months ago) rolled over to a Roth IRA. Can I pull this out as a first time home buyer? If so, can I pull this out any time during the tax year the home was purchased? What would be considered contribution vs. earnings, the full rollover amount or the contributions into the original 401k? Also i underdtand it needs to be five years old, does the 401k time count or ony since rolled over?

thanks,
