Renting in Diamond Bar

• The Country Estates. Large homes in the gated community attract executives and families on long leases, and call for careful screening and detailed documentation.
• Hillside neighborhoods. Homes on the city's many hills offer views and need attention to slopes, drainage and brush clearance.
• Near the 57 and 60. Townhomes and condos close to the freeway interchange suit commuters headed to Orange County and Los Angeles.
• Near Diamond Bar High School. Family homes within the Walnut Valley Unified School District lease fastest ahead of the school year.

Many Diamond Bar renters are families choosing the Walnut Valley schools, professionals working in the San Gabriel Valley and Orange County, and households relocating from overseas who rent before buying. Cal Poly Pomona and Mt. San Antonio College are nearby.
