1. First, have an aggressive list price. That means realistic, not high. When I first listed my house for sale, I used a survey that was a year old. Bad move!!! The survey was out of date and not in line with comps in the area. Comps are important!!! Do not under-estimate the importance of comps. Comps keep you in the competition.
2. Use an experienced real estate agent. Why is this so important? An experienced agent will have lots of connections and is more likely to help you set a good list price. Find someone with 20 years or so.
