The three reasons a house doesn't sell: price, condition, marketing. No one is fooled by an overpriced listing, least of all other realtors. If you have changed your price three times already, chances are you started too high to begin with. A house receives the most activity that first month, that is why market pricing is so critical from the beginning. After that first month, price reductions receive little attention.--"been there--seen that " is the public's attitude. The property is old news. The closer the comps are with regard to year built, square footage, location, selling time frame, the greater your accuracy to pinpointing the correct market price. Listing price cannot be based on emotional value. It is helfpul to pull a comparative market analysis each month of the listing in order to stay up with the changing market and make appropriate changes as necessary to the listing price. Ask your Realtor for a current CMA.
As for condition, it should look as close as possible to a model home. Declutter (clear counters, cabinets, closets), depersonalize (put away excessive family pictures, so potential buyer can visual himself/herself living in the house), dramatize (afghan across sofa, open book on reading table, fresh flowers, music, scent of vanilla in the air, paint inside and out, yard manicured). Don't defer items that need maintenance. Spotless and clean "wow's" buyers everytime. Ask your Realtor about staging your home to accentual the positive and downplay any negatives.
Marketing is the Realtor's job. No stone can be left unturned. Internet, Realtor's website(s), company website(s), local Multiple Listing Service, other brokers notification through open houses, flyers, emails, word of mouth, public open houses, attractive yard signs, visual tours, etc. If it's priced right, in top condition, and marketed well, it can't help but sell. You control these variables. Take charge and get it sold!
