I've calculated that I will be able to save approximately enough for a 20-25% down payment on a home (at my back-end-ratio affordability level) in the next 2-3 years. I'm maxing out contributions to my Roth IRA already, and plan to withdraw $10k from it for the first-time home purchase. I've also already saved up ~6 months of living expenses, and have 0 debt to pay down.
I believe I need something in the middle ground for risk/reward. I'd like to earn at least some return on the savings greater than a savings/cd/mm account, and can even tolerate a loss of 10-15% if it means waiting an extra 6-12 months to recover from an event like that.
What's a good investment vehicle for my needs?
