Here are a few of the open houses in Belmont this weekend.

In fact, this week, how about the homes that are selling for a pretty penny; more like 100 million pennies: homes that are listed for more than $1 million. And according to the Seattle-based real estate brokerage firm Redfin, the most expensive one percent of homes nationwide are hot, hot, hot, with sales up 21 percent since January, while sales of the 99 percent of “lower end” housing are off 7.6 percent.

“There are haves and have nots, and the haves are the ones out buying,” Redfin CEO Glenn Kelman said.
