Premium Infill Opportunity in Southwest Longmont.
Nearly 3 Acres With Strong Development & Entitlement Potential.
A rare large-parcel infill opportunity in one of Southwest Longmont’s most desirable growth corridors. This nearly 3-acre property blends privacy, mature trees, and an established custom home with the kind of development flexibility that builders and investors actively seek.
City utilities are stubbed directly to the edge of the property, significantly reducing off-site extension costs and making future planning more predictable. The parcel sits within the Longmont growth boundary and is surrounded by established neighborhoods, offering a natural fit for future residential development. Flat topography, excellent solar orientation, and straightforward access from the western frontage support multiple subdivision or estate-style concepts depending on a buyer’s vision.
A unique advantage of this property is its alignment with the City’s long-range transportation plan. Longmont needs a portion of the frontage to complete Mount Audubon Drive, creating a rare scenario where the City is motivated to negotiate entitlements, access, and improvements. This can streamline timelines and open the door to cooperative solutions not typically available in infill projects.
The existing home is nestled among mature trees, offering a private estate feel that can be preserved, renovated, or incorporated into a broader development plan. Outbuildings add optionality for storage, staging, or removal.
The sellers are also willing to work collaboratively with a developer throughout the annexation and entitlement process, including offering flexible financing structures during that phase to support a smooth and efficient path to approvals.
