How we ranked these SA lenders

For each lender we calculated a score using three signals:

  • Lowest variable rate (0–2.5 points) — inverted against the field, so the sharpest rate gets the maximum bonus.
  • Editorial rating (0–5 points) — from our independent lender review.
  • Home-state presence (0–2.8 points) — bonus for HQ in SA, community presence, or Big 4 / digital national availability.

Affiliate partnerships are not a ranking factor. The score is deterministic and reproducible from the data on our public lenders page. Rates change frequently; the ranking is reviewed periodically.
