A A. There are certain restrictions when it comes to borrowing money from your Roth IRA. While you can't take out a loan from your Roth IRA like you can with other retirement accounts such as a 401(k), you may withdraw funds for short periods of time. The withdrawal of these funds are tax-free, penalty-free and interest-free, according to Bible Money Matters.
You can use the money to buy or build a first home for yourself or your spouse, kids, grandchildren or parents. The money must be used to buy or build the home within 120 days of the withdrawal. You can get a bigger break if you withdraw the money from a Roth IRA. You can withdraw Roth contributions tax-free and penalty-free at any time for any reason. After you withdraw your contributions, you can withdraw up to $10,000 in earnings for a first-time home purchase without a 10% early-withdrawal penalty.
