Arlington is hottest place in Eastern Mass.

His modest two-bedroom home in Arlington Heights was listed on a Friday for $459,000. By Saturday it had had several private showings. The next day, after an open house, he received eight offers at or above asking price, so he asked the four highest bidders for their best offers. On Monday the house sold for $480,000, more than a 50 percent profit on what he had paid for it three years earlier. "We were expecting, in an ideal world, to get our asking price, and we would have been very satisfied with that," said Stewart, a software engineer who moved to a bigger house in Bedford with his wife and two young children. The final price and quick sale, he added, "blew us away."
