I just pulled up your listing. The pictures are pretty good, and the house is in great shape. However, it is definitely dated. Here in AZ the homes that are going fast are decorated and furnished in the more modern/contemporary style. Gray walls, etc. Homes that are in the current style and move in ready sell first.
However you are in a price bracket that just takes longer to sell, so take that into account. It could take 90-120 days to find a buyer, and we are coming into the slower time of year.
I have no idea if its priced too high, but this chart explains some of that...
