Two things: First, the market has slowed significantly. Some suggest it is because of exchange rate shock others point to overly ambitious pricing.
Look at the properties for sale in your area and do an honest comparison of features and price to yours. In a slow market the best pricing strategy is to offer more value for money than the competition. Make sure you have prepared the places well, decluttered, manicured landscaping, paint and repairs where needed.
Second, look for the agency or agent that seems to sell more homes in your area.
