In my twenties, I saved my ass off until I had a year's salary in the bank to buy my first house. Unfortunately, I lived and worked in a high COLA, so I bought a rental house in the (less expensive and not too far away) town that I grew up in. I never put anything into an IRA or Roth, as I knew I was going to spend the money on a house. Later I sold it and moved to an area where I could afford to live in the house myself. I kept stepping up the ladder. I bought a nicer house in 2001 and a rental house in 2004. Unfortunately, I no longer count either of them in my net worth. While I'm not upside down in either of them, they are not worth a whole lot more than I have in them, especially if I count selling costs.
So, after all that back story, my advice would be to study the amazing magic of compound interest. Keep saving for at least another year. Start and fund any and all retirement vehicles available to you. The housing market will take some time to rebound. Make sure you want to stay in your area. You don't want to feel trapped. It's an awful feeling when you're counting pennies because a roommate vanishes without paying rent and then something big breaks. You're absolutely on the right track, but if you take a little more time to learn and prepare, you won't regret it.
P.S. I did start dumping cash into retirement vehicles, but not until I was in my thirties. I will have to save much more than I would have if I'd started in my twenties. I don't regret owning real estate at all, I just wish I'd "stached" some cash in retirement vehicles a lot sooner.
