Early withdrawal from Roth IRA for DP

[James Fraundorf]

Question for an a cpa/accountant, I want to take an early withdrawal from my Roth IRA (contributions AND earnings) to buy my first property (not a primary residence). I know there's a 10% early withdrawal penalty for earnings but I read somewhere that is waived if you're purchasing your first property?? Also, once I withdraw my contribution and earnings is there a 60 day window where I can put those funds back into my Roth account? Thanks!
