With the rise in use of sites like Zillow and Trulia over the last few years, buyers have started putting a much greater emphasis on measures of value like the average price per square foot (PSF) of homes in a neighborhood. I always caution clients when doing this, because unless you are comparing identical floor plans in the same building, there will be too many variables involved to give the PSF a 1:1 value. This doesn’t mean that you should disregard the number altogether, just use it more as a gauge as opposed to a pair of apples.
