FSBO can be the best option for Union sellers and buyers who are looking to save time and save money. Using a third party to act as a negotiator can slow down a sale, sometimes it is best to speak directly to each other to express concerns or any thing that would impede a smooth purchase. A Union buyer may have obstacles holding them back, for example, selling their property first. By directly settling terms, a Union seller may be willing to write up a contract and work with the buyer to fix any hurdles and what may have been a no-sale has turned into a sale due to direct communication.
