Jmetx,
Real estate is a great investment, but just be aware that it will carry a certain degree of risk (as navywareagle has pointed out). First piece of advice to you would be to read as much as you can. Two books that got me off on the right foot are Kiplinger's "Buying & Selling a Home" and Bridget McCrea's "Home Buyer's Question and Answer Book." Start looking over your credit reports and find areas where you can make improvements. Start shopping for cheap interest rates, perusing the MLS and contacting Realtors if you choose. Bottom line is to research this decision as much as possible; hell, it may cost more than anything you ever buy again in your entire life.
I'm a primary student in Corpus (for 2 more days at least) and decided to purchase a condo out here and found that no matter how much research you put in, there will still be unforeseen expenses. Just make sure you factor in HOA fees, property taxes (these are a ***** in TX), insurance costs (if not covered by your HOA dues), and other miscellaneous costs in addition to the principal and interest payments.
Shoot me a PM if you have any specific questions.. I'm more than happy to elaborate on the benefits / costs thus far.
