Cover letter for Real Estate

[David White]

I have to write a cover letter by September 30 for this job post: http://baltimore.craigslist.org/rej/5231828309.html I've never written a cover letter. Does anyone have any tips and/or suggestions as to what I should include in it? I believe this is my best opportunity to gain entry into the real estate business. So, I'm not trying to blow it by a less than par cover letter.
