Realtix plan

Desk analysis complete, based on the listing and market data. Figures not confirmed by documents are marked as estimates. This is Realtix's own view, not investment advice.

Strategy: Core-plus 78704 hold

Strengths

  • 78704 location near South Congress, Bouldin Creek and Lady Bird Lake
  • Townhome layouts with private yards and in-unit laundry attract longer-tenure tenants
  • Fully leased with stated gross income

Risks

  • 1971 construction likely needs plumbing, electrical and roof review
  • No NOI or cap rate stated, only gross income
  • 78704 pricing leaves thin cash flow at current interest rates

Catalysts

  • Interior upgrades at turnover to push rents
  • Long-term land value in one of Austin's tightest zip codes

Due diligence still needed

  • Request the Southway Flats OM and trailing 12-month operating statement
  • Confirm lot size and zoning with Travis CAD and the City of Austin
  • Inspect sewer lines and electrical panels on the 1971 buildings

How this score works

The score is calculated, not hand-picked. Cash flow (40%) scales the estimated cap rate from 2% to 8%. Price (25%) scales price per square foot from $320 down to $120. Building age (20%) scales the year built from 1955 to 2015. Data confidence (15%) is higher when rents are reported rather than estimated. It ignores location quality, condition inside the walls and tenant quality, which need diligence.

Realtix preliminary screening score. Not investment advice, and it does not predict returns.
