When it comes to expensive houses, this Boise-area suburb is king. Why is it so popular?

It might be surprising that some of the biggest cities in Idaho don’t have the ritziest homes.

No, for that you need to go to Eagle. With just over 35,000 residents, according to the Community Planning Association of Southwest Idaho , Eagle has five of the six most expensive homes ever sold in the Treasure Valley.

That sixth home? It’s not in Boise, Meridian, Nampa or Caldwell. It’s in Star.

All six of these homes found new buyers in 2022 and 2023, and all had sales pending within three months of hitting the market — remarkably fast by historic Boise-area standards for the sales of seven-figure houses.

And sales of these super-high-end homes are picking up, according to Matt Bauscher, owner of Bauscher Real Estate and founding partner at Amherst Madison Real Estate Advisors. Bauscher sold a newly built $5.2 million home near Farmers Union Canal north of Eagle in April.

“It used to be rare for a million-dollar home to sell,” Bauscher said by phone. “We’ve come a long way.”

In 2019, there were only three sales over the $3 million mark in the Treasure Valley , he said. That number increased to 22 in 2023, with five at or above $5 million.
