Personal residence sale tax question

[Joe D.]

I did a search to see if I could find anything on this but no luck. I am about to put my personal residence up for sale within the next month. At the moment I haven't done any investment deals so I don't have any experience with this. The way I understand it is if I list my house with an agent I can write off the real estate commission that I pay the agent for an investment property. Correct me if I'm wrong on that. But someone told me tonight that I could do that for a personal residence too. Is that possible?
