If your house gets lots of attention and you get good offers, stay the course and be prepared to give up a little of your savings to close the deal. But if the process drags on without any real bites, hire an agent. You’ve lost nothing but time, and you’ll enter the agreement with a far better understanding of how it works and how to get the most from your agent.
When you're buying a property for just a few hundred bucks (which is how most of my deals work) and you're already on a tight budget to begin with, it can be difficult to justify paying twice the amount of your purchase price just to close the darn thing. If you're in a situation where you need to act fast, acquire a property inexpensively and make the closing as easy as possible, closing it yourself may be the most advantageous way to move forward.
Now, far be it from me to discourage using an agent. This certainly is the easiest way and not necessarily the least profitable or most expensive, especially in a booming market. In a less-than-booming market however, it’s good to remember that listing your property with an agent will subject it to comparison with dozens, perhaps hundreds of other listings, all competing with yours in features and price. Selling your property then, will probably require that a potential buyer finds it to be either the best he sees… or the cheapest.
I agree with Ellen Chung, finding the right type of buyer to target is very important. Also, you should consider the amount of time you have to sell the land. If you are short on time due to back taxes owed or other financial obligations, your best bet may be to talk to a vacant land investor. You will not get the full market price for your property, but the typically can pay cash and close quickly.
