And yet you "wasted" even more of your time telling me what I don't know.
Me. Make $110K per year. Max 401K plus over 50 catch up. Bought a rental house for cash. Looking at another one this week. Have one year emergency fund (as in I can maintain my level of living for one year without an income). Have excess cash and I thought I'd look in to Roth's. Degreed accountant. So yes, I guess I don't know much.
Oh, yeah, it wasn't *you* whose time-wasting I was concerned about (since you invested almost no time in creating your initial post), it was the collective time of 50 people coming and posting their Roth IRA details that I was trying to cut off at the pass. Since I'm such a selfless martyr, I was willing to waste my own time in pursuit of that noble goal!
Ok, so now we at least have a better idea of where you're coming from. Investing in a Roth IRA is probably a good idea for you (assuming you're single; if married, a Traditional IRA might be an option to consider too). If your poll had actually been completed, the responses would have likely congregated around something like this:
http://www.bogleheads.org/wiki/Three-fund_portfolioOr more explicitly, what=low-cost index funds, where=Vanguard, fees=none, interest rate=unknown
Though that "Three fund portfolio" wouldn't necessarily all be held within your Roth account. One part might be held in your 401(k), another in a Roth, another in a taxable account, etc. So knowing what someone holds in their Roth IRA isn't too useful unless you know what the rest of their portfolio looks like.
