The most proven way to get a full fair market price for your home is by listing your home with a licensed real estate agent.
An agent can market your home through the MLS (multiple listing service) which is where 90% of people go to look for a home to purchase. Agents also have experience in pricing and marketing homes to sell. Of course some agents are much, much better than others, and it's critical to choose the best one - namely one that has EXTENSIVE experience. Hiring an agent is like buying an insurance policy. When things go wrong (which is common in real estate) having the right one will save thousands or tens of thousands of dollars.
