Anthony,
I'm a n00b right now, too. I'm 27, have a mortgage on my current residence, but haven't made a purchase for investment yet and I work the rat race still, just like any other aspiring investor here. That's just so you know who you're hearing this from.
But it's two words that give me unwavering confidence: LIVE DELIBERATELY.
Ever since I was about 12, I've had a vision in my head about where I wanted to end up, what I wanted to do, what my lifestyle would be like, etc... Every major decision I make and have made up to this point is pretty much based on the result of one question: "Is this going to help me get there or not?" It's probably not surprising, then, that I'm a single guy who still works full time and lives well below his means. Heck, I still drive the same car I drove in high school. OK, so that one's a bit wierd, but it's a neat car and I enjoy it. No one said you shouldn't have fun along the way!
I'm learning what it takes to get started in this, and I'm working to get myself into a great position to begin. When thinking about my excuses for not yet starting (thread topic), I made two lists: reasons for not starting, and reasons why I should. The end result was 4 and 4. They cancel each other out. So I do nothing.
The main reason for not starting at this point is that I just don't know enough yet - how to find a place, how to finance it, what to do with it, how to market it, how to deal with the taxes, etc... There's a lot to know! Once I can answer the main questions from the beginning of the deal to the end of the deal, the tally will be 5 reasons to do it and 3 reasons to not. That's 2 more reasons to do it. I'll know what to do, and I'll do it because that's what will get me to where I want to be. I can't wait to get started!
