Here's how you do it.
1. Go to Zillow and claim your house. Click on "Make me Move." but don't stop there. Put in a description of your house and clearly indicate that you are open to discussion!
2. When Real Estate agents call you (because they will) wanting to represent you as a seller's agent, tell them you're only interested in paying them a flat fee for basic counseling and helping you complete forms. THAT IS IT. When they say no, tell them thank you very much and hire a law firm.
3. Wait for buyers to come to you. Do all negotiating verbally unless you want to jump right to lawyers (paid by the hour--shouldn't take too many hours) or your Real Estate agent-hired-for-a-flat-fee. All it takes is that.
You will have spent less than $2000, guaranteed, to sell your house.
