Hi J. -
I am a realtor and live in Highland Village. I'm not sure how long your home has been listed, but the past couple of weeks we have had school starting and Labor Day, which could affect showings.
If you aren't getting showings, ask your Realtor what other creative marketing he can do to get people inside the home, ie. Open House, Realtor tours, etc.
Sometimes we will do an Open House and get 15 people, and struggle for showings. Open Houses in general do not sell "your" house, however it's the traffic that is needed.
Other things to take into consideration, do you have a virtual tour? PHOTOS, PHOTOS, PHOTOS!!! people are looking to see your home, and if they don't have much to see, they move on. Also, where are you being advertised?
Then lastly, once ou start getting people in the home... you have 3 reasons it won't sell, Price, Condition & location. Obviously location isn't something you can control, but simple staging can make a huge difference, and you have to be priced competitively.
Hope this helps!!! L.:)
