You should be concerned. Not about the carpet. About the fact your home has not sold in three monthsl.
The truth is that the buyer that first sees the home they buy sees it with a Realtor. 90% of the time. So if you are not receiving showings, then the price is too high. If you are receiving showings, but no offers, the price is too high.
Buyers want value. How many homes, like yours, have sold in the last three monhts? Why did they sell and not yours? Realtors and their buyers thougth that the other properties offered more value. One of your Realtor's main jobs is to expose the value of yoru home to the market. There are different ways to do that,price being the primary means of comparison.
Homes that sell in the first 30 days sell closest to asking price. Homes that sit, sell for ltess. Right now in my market a home that sits for 120 Days On Market sells for 93.6% of asking. Within 30 days they sell at 98.5% of asking.
