Market Analysis: 78384 San Diego

ZIP 78384 inside San Diego, TX leans into a value-add thesis. Home values near $72K sit below the state median, and rents of $1,080/mo leave room for forced-equity plays.

Flippers and value-add operators have treated 78384 as a working ZIP for a reason. Entry prices around $72K and a deep rental base of 23% renters underpin the exit strategy on both the sale and rent sides.

In Duval County, 78384 is part of the operational map, not the passive one. The spread between median price and renovated comp reflects the work available.

A renter-heavy, wage-earner demographic anchors 78384. Value-add players rely on that mix — the 23% share is both the tenant source and the buyer pool for future owner-occupied exits.

Flippers with local expertise can do well in 78384. Out-of-state investors should partner with boots-on-the-ground operators or skip the ZIP entirely.

About Repit School Scores

Traditional school ratings rely heavily on standardized test scores, which often reflect family income more than school quality. Repit takes a different approach.

We evaluate schools based on factors that research shows actually impact educational outcomes:

  • Class Size — Smaller classes mean more individual attention
  • School Funding — Resources available for programs, staff, and facilities
  • Community Factors — Neighborhood characteristics that influence student success
  • School Environment — Size, type, and structure

Scores are updated annually using federal education data.
