Investment Insights

Based on property information with market context.

This two-story duplex features two separate living units on one property. The lower unit has been renovated with updated finishes, including a transformed kitchen and a newly renovated bathroom. The renovation also added a new bedroom with a new en-suite full bathroom. The upstairs unit has been used as a rental.

The property is located at 525 W Magnolia Ave in San Antonio’s Alta Vista area. It sits on a 0.144-acre lot and contains 2,260 square feet of total building area, providing a compact, income-focused setup for an owner-occupant or an investor.

For buyers seeking a straightforward residential income property, the duplex layout offers two units under one roof, with renovation work completed in the lower portion of the building. The upstairs unit’s history as a rental can support continuity for an operator looking to manage both levels. This configuration can also appeal to households that want to live in one unit while maintaining rental income from the other, subject to applicable local regulations and leasing decisions.

Key Highlights

  • Two living units offer flexibility for rental income or multi‑generational living.
  • Lower unit features stylish, updated finishes throughout.
  • Renovated lower unit kitchen.
