Many factors affect home values: quality of location within the market area, architectural style and curb appeal, square footage, condition, views, amenities, extra rooms, parking, decks and yards, privacy, lot size, demographics, environmental factors, and so on. There is usually a wide or even vast variety of homes within market areas, especially larger ones. Remember, this is not the value of your home, but the market you live in. Median values are those at which half the sales occurred for more and half for less.
