Most listing agents usually get 6% of the sales price , but it is negotiable. There is no set commission. The listing agent splits the commission with the buyers agent.
Here is a tip: It helps to give a bonus to the buyers agent when listing. Statistically speaking the listing agent gets a buyer less than 2% of the time. So buyers agents are key to a quick sell. If you plan on selling in 3-6 months you have to market aggressively and market at the right price.
Good Luck in your sale!

I would clear a portion of the land, not the whole thing. The terrain is also a factor. There is a value many buyers living on the outskirts of a city will do. I'd recommend leaving the perimeter wooded for privacy. We had 10 acres of cleared land and it was always windy, just a tree line will make a huge difference.
