No question that checking sold sales is the most meaningful indication of prices.
I appreciate the open house advice but I'm not sure that is a solution. Rarely do homes sell via an open house. If you do one, it must be well exceptionally well marketed and advertised online (where buyers are looking). Otherwise, you are just hoping to get 'lucky' when someone drives by.
Curb appeal plays a role - but only to those that show up.
The first concern is getting people to come see the home. You need an 'at bat' so to speak, to even have a chance of hitting the ball. What attracts people to want to see your home?
With regard to price, it's critical to understand the market you are in. In my market place, the homes that sell aren't just priced at market value. With the state of the economy and the overall housing market, buyers only are willing to take the leap on homes that are a 'good deal'. When they stand around the water cooler at work justifying buying in this market, they want to be able to say, 'I got a great deal'.
If you have to move, and you don't want to lease the property, price it to get showings. Then, of course, make each showing count by keeping your home in spectacular showing condition.
Hope this helps. All the best to you and good luck.
