What are investment options for young married couple with no debt that have maxed out retirement savings?
You can't max out your retirement savings. There are vehicles that aren't tax-advantaged that you can fund after you've exhausted the tax-advantaged ones.  Consider how much you want to put into these vehicles.  There are disadvantages as well as advantages.  The rules on these can change at any time and can make it harder for you to get your money out. How's your liquid (cash) emergency fund?  It sounds like you're in a position to amass a good one.  Don't miss this opportunity. Save like crazy while you can.  Kids make this harder. Paying down your mortgage will save you interest, of course, but make sure you're not cash-poor as a result.  If something happens to your income(s), the bank will still foreclose on you even if you only owe $15,000.  A cash cushion buys you time.
