Why Mountain House

A planned community that grew into a city.

Built village by village

Mountain House was laid out from the start as a set of villages, each with its own school and park. The first homes were built in Wicklund in 2003. Newer villages, including College Park and the Lakes, are still adding streets today.

The western edge of the county

Mountain House sits at the first exit east of the Altamont, where I-205 and I-580 divide. For buyers coming from the East Bay, it offers newer homes and more room without giving up the commute.

Now a city of its own

Residents voted in 2024 to incorporate, and Mountain House became the newest city in California that July. Safeway and the Market at Mountain House opened in 2022, Town Hall and the library in 2020, and a new fire station is under way. Errands that once meant a drive to Tracy now happen in town.

The villages

Each village has its own character and its own buyers. A twenty-year-old home in Wicklund and a new build on the newest streets are marketed differently, and Jack has sold in all of them.

Jack Klemm, broker and owner of Klemm Real Estate
Serving San Joaquin County since 1988

The broker who answers his own phone.

Jack Klemm has been selling homes in Tracy and the surrounding communities since 1988. Nearly four thousand of them. He is not a team with his name on it. When you call, you reach Jack: the same person who prices your home, coordinates the contractors, and negotiates your contract.

Klemm Real Estate is his own independent brokerage, so there is no franchise playbook and no hand-off to someone else. Just a broker who has watched this market for thirty-eight years and knows what homes on your street sell for.
