Posted this another thread so I figured I'd put it here to, which I see echoes everyone's sentiments :)
@Jinyu Shao granted I'm an agent, but I truly think this is a bad idea. If you're out of the country, you're going to need to pay another agent to show the apartment for you, handle the listing, marketing, open houses, etc. You're spending time and money to not only get your license, list, advertise, but then you have to find a broker who will hold your license only for you to sell your apartment, and that broker will require a commission as well. Like my clients and others who use agents as well, you'll find that a good agent is worth every penny. With all that said, you could still sell as for sale by owner but will still need the above.
1) Can I represent myself to sell my co-op in NYC? (I know it's possible in some states, not sure if it's the same in NYC) - Yes you can. You just have to disclose that you are the owner.
2) Can I do so while residing and working in a different country? (I can fly back for closing or other events that requires my presence) - Yes, though you don't even have to be at closing...you can grant power of attorney or pre-sign documents.
3) If both of the above are okay, when do I need to be physically present? - showing, open houses, broker tours, etc. or pay someone to do it for you.
4) Once I take the class online and pass the exam, what's next before I can represent myself to sell my property? - find a broker who will hold your license for you, though they're going to require fees from you and part of the commission.
