Do you already have good reserves of at least 6 months' living expenses, or is the 10k your life savings at the moment? Don't let greed make you gamble with your reserves is all I'm advising....in fact, I'd put some of those reserves in physically held precious metals for two reasons - they won't deflate, and it adds an extra obstacle to spending them foolishly.
There are owner-financed investment properties out there that make sense, the $10k could cover closing costs on a couple of those. There are also "Lonnie deals" being worked in mobile homes by many BP members, with good profits, for well under your $10k limit. Maybe not in your area though.
If you've decided that you want to invest long term in real estate, I don't see a reason to invest a lot of time in learning about flipping used cars or other unrelated transactions. Just keep networking, educating yourself, saving, and watching your credit. Opportunities will present themselves. Hope you have a successful 2010!
