Real Estate Market

The Old Mammoth real estate market showcases remarkable diversity in housing options, from charming vintage cabins that harken back to the area's early days to contemporary single-family homes and well-maintained condominium complexes. This variety allows buyers to find properties that match both their lifestyle preferences and budget considerations. Many of the older cabins have been thoughtfully updated while preserving their rustic character, featuring exposed beams, stone fireplaces, and natural materials that complement the mountain setting.

With a median home value of $569,000, Old Mammoth properties represent solid value in the Mammoth Lakes luxury market. Single-family homes in the neighborhood often feature larger lots compared to other areas of town, providing space for gardens, outdoor entertaining, and parking for recreational vehicles. The condominium complexes tend to be smaller, well-managed communities that offer maintenance-free living while still providing the privacy and space that mountain residents desire.

Properties in Old Mammoth are particularly attractive to buyers seeking year-round residences rather than vacation rentals. The established nature of the neighborhood means mature landscaping, developed infrastructure, and a sense of permanence that appeals to both retirees and working professionals. Many homes feature mountain views, and the slightly elevated position of some properties provides glimpses of the surrounding peaks that define the Eastern Sierra landscape.

Schools & Education

Old Mammoth falls within the Mammoth Unified School District, which serves the educational needs of the greater Mammoth Lakes community. The district operates several schools that accommodate students from kindergarten through high school, with a focus on small class sizes and individualized attention that reflects the close-knit nature of the mountain community.

Families in the neighborhood appreciate the walkable access to school facilities and the district's commitment to outdoor education programs that take advantage of the spectacular natural classroom provided by the Eastern Sierra.

The central location provides easy access to Mammoth Yosemite Airport for those traveling to urban areas, while the town's free shuttle system includes stops throughout the neighborhood during peak seasons. Most daily errands can be accomplished on foot or by bicycle, though residents typically maintain vehicles for accessing trailheads, ski areas, and destinations throughout the Eastern Sierra region.
