The selling price of a house fluctuates depending on multiple factors. The most common ones are the neighborhood and what similar-sized houses are currently selling for. Also, look at the age and condition. Do major repairs need to be done? If so, that might lower the property. And again, the market matters. Like everything else, home prices vary depending on supply and demand. Your job as a realtor is to best inform your clients about these different factors and accurately list their house.
