I think that you are focusing on the wrong aspect of the sale.
When a Realtor markets a home we have certain expectations. Normally, if a home is properly priced and marketed, we expect 10-12 showings in the first two weeks, or a price reduction is in order. In most cases 10-12 showings will result in an offer, or again, a price reduction is in order.
In most markets homes that sell in the first 30 days sell closest to asking price, so generally speaking the longer a home sits on the market , the greater the gap between asking and selling price, which means the home starts losing value. For example, in my market, a home at 120 Days One Market (DOM) averages 93.6% of asking, compared to 99.5% within 30 days,
So if your Realtor is not seeing showing activity, then you need to lower the price. Things like the street, the house, etc. are pretty much out of your control as the seller. Focus on the results you expect.
when you hired your Realtor you looked at comparable homes on the market. Since your home has been on the market, what has happened to those homes? Sold? Lowered their price? Most buyers look at 10-12 homes before they make an offer, so chances are by looking at your competition you will be able to determine what you need to do. If other homes are selling, and yours is not, then you need to take action.
