Belleair Shore is home to the most expensive homes in Tampa Bay. Truly residential, Belleair Shore is only on the west side of Gulf Blvd. Belleair Beach takes up the intracoastal side of GB, and gazes aimlessly across the street that is the man-made beauty. If you’re staying in IRB or Sand Key, spend an afternoon walking the beach on Belleair Shore. Remember this IS reality. Oh and that really, really big one. The guy that owns that makes more money in one year than the cost of the house!
