Most people are familiar with Zillow's "Zestimate" where the website will suggest a value to a listed property as a "guideline" for prospective buyers.  Zillow gathers this information by doing the work that buyers aren't often able to easily do which is to gather sales data from nearby properties that have recently sold.  Imagine, if you will, a dreamy street on Hilton Head Island where you want to buy your next home...one side of the street is Oceanfront homes and the other side of the street have "wooded view" properties.  Zillow can't differentiate price difference based on view so guess what?  All those "wooded view" suggested property values will be inflated based on recent sales of Oceanfront properties.  Don't overpay.  Use a buyer's agent (they are FREE to you) to purchase your property on Hilton Head Island.
