Save your money, rebuild your credit and wait. Any loan you would likely come across now would be very expensive. Even after the required time expires, typically 5 years after a foreclosure, you'll need a solid credit profile to be considered.
Rebuilding credit is a commonly missed but critically important step to be ready when the time comes. Start with your bank, you may get a collateralized credit card. Take out some store cards when you can and pay everyone off right away. Auto loans are another good place to get your credit re-established, just don't get carried away.
