BOYLE HEIGHTS — It was only a year ago that this Queen Anne-style Victorian on Fourth Street was struggling to find a buyer. An admirer of the home even began a personal campaign to find a buyer who would restore the nearly 120-year-old home. Then last summer a flipper purchased the property for $250,000 and proceeded to restore and renovate the house, which was painted a shade of aqua with pink, gold and yellow accents. The house returned to the market late last year at $450,000, according to Redfin. The three-bedroom home finally changed hands at the end of last month at its asking price of $450,000. That, according to Redfin, is the highest price paid for a single-family home in Boyle Heights during the last three years. Can those prices go any higher?
