I agree with Flame. A GOOD realtor is worth their weight in gold. Unfortunately, most realtors list your property on the MLS, sit on their butt and wait for their check. If you can find that person they will be worth the 5%-7%. Only if you have done all the market research would I dare go it alone. I have done multiple real estate deals and I always come out better with a GOOD realtor on my side. Ones I did on my own did not go as well. Find one that specializes in your type of land. Get feedback from old customers. If they specialize in that type of property they might even have buyers already looking.
