There's nothing wrong with waiting if its not the right time. Its all about how much risk you are willing to accept as an investor. If you can find a really stable property in a stable market, then maybe its ok. For me personally, if I risked it big before I was ready and went bankrupt, I would have an awfully hard time getting anyone to ever invest with me...Not to mention you will have a rough time getting a loan in the near future or renting a nice house. We jumped in with little money in savings, but I had multiple escape routes if things went south. We bought the property below market value, the property came with stable, long term tenants, and we had parents willing to help us out short term if things went poorly. Not to mention my income is fixed so there is a lot of income predictability and stability.. That's 4 escape routes. Just make sure you have your own escape routes jumping in, because the water is cold an deep in some spots...
Remember, too, people have been "investing" in real estate for hundreds of years. I don't think its going to suddenly end tomorrow.
