The first question you need to ask yourself is what are you looking for in a FSBO website? There are dozens of them available and some offer additional services that will get your home the home the exposure it needs to sell in a market with a high inventory. You might also find a flat fee agent in your area who will get your home listed in the local MLS gaining you needed exposure among other agents with qualified buyers. Good luck.
If you are thinking of selling and need to net the most when you close escrow. I suggest interviewing three Realtors, compare, then select one. You might be able to sell on your own, however know that 85% of those selling without professional representation eventually list with a Realtor.
If you'd like a referral to a top agent in your area just let me know.
