The home down the road may have sold for $500 per square foot, but that doesn’t mean yours will. Remember that the price per square foot is really just whatever a property sells for divided by the square footage. As such, the number can change drastically depending on a multitude of valuable factors, including the view, whether or not there’s a pool, etc. This might not be as much of an issue if you’re in a high-rise condo, but it’s not uncommon to see some variance within a neighborhood.
