I Sold couple of my own properties, one being a realtor and me without being. The one when I was not a realtor and I sold it was a typical "Seller" mentality. I used to tell my Realtor that " want so and so in my pocket". In my experience it did not work and the reason was I was not matching my asking price to the Market value and I was not motivated Seller. The property did not sell for 70 days and then I was worried. I followed what my Realtor Said and the property was sold.
I did not do this mistake when I listed my another property as myself as a relator right at market price and I got an offer in two days and property was sold in 10days.
