I have worked in Sewickley for years. My office is right in the village. I assume that your townhome is in the Manor. If so, there have been 16 sales in 2009, but currently there are 13 active properties and 1 that is contingent. This year we have seen the highest inventory in the manor that has occured for a number of years now. With that, buyers have lots of choices and price/condition become even more important. I too would not advise you to rent, as it is rare that an owner can get a renter who will be willing to allow the property to be shown often. You then face the problem of what condition the tenant will keep the property in during those showings. Remember you do not get a second chance to make a first impression. I would ask how and where your agent is advertising your home. Provided that your condition is good, and your price is on target, then strong marketing/advertising will be the most effective in producing a buyer sooner then later. You need more then a sign and an occasional ad the company may provide. To answer your last question, I do not see huge changes on the horizon. Properties that are priced well, are in good condition and have strong advertising still continue to sell. If you would like more assistance, do not hesitate to call.
Keep your home show-ready at all times. Never turn away a person that wants to take a look-see. If they don't buy - they could know someone who will. Keep your lawn clear and if you have pets - pick up after them.
Make sure you and your agent are leaving no stone un-turned! Buyers are out there, you just have to find them. Are there renters in your subdivision who would like to be "owners"?
Changes in the market will be slight within the next few months. We are in the peak season and the closer we get to the beginning of school sessions - the pace will get frantic. Hang tight, have faith, and stick to your end of the bargain!
