Investment Insights

Based on property information with market context.

This property is configured as a duplex-style setup with a 3-bedroom main home and an additional detached casita in the rear. The casita includes a kitchen and a one-bedroom layout, providing flexibility for rental income or extended family use. An alley provides access to the rear unit, supporting convenient separate entry and service to the back residence.

Located in Calexico, CA in Imperial County, the property sits on a 0.16-acre lot. With two separate living areas on one parcel, the arrangement is designed for multi-tenant occupancy and easier management of day-to-day household needs.

The rear detached unit and alley access may also appeal to tenants or operators looking for convenient separation between occupants. Additional parking and/or future improvement potential are noted in the remarks, offering room to consider how best to utilize the site over time.
