What matters now
- The price is below even our cautious bear case (€20.67). The market is more pessimistic than our downside scenario.
- Solid quality (61/100) at a price below fair value, the discount is the argument here, not the business quality.
- A fairly wide model range (€20.67 to €37.71) leaves room in how you read the outcome.
- As a real-estate business, asset- and dividend-based methods carry more weight here than a standard DCF.

Analysis
Inmobiliaria del Sur, S.A (ISUR) currently trades at €16.50, while our model-based Fair Value estimate is €30.17, implying the stock looks roughly 82.9% undervalued today. The Quality Score stands at 61/100 (solid quality), in the Real Estate sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: high), always confirm before acting.
Over the trailing twelve months, Inmobiliaria del Sur, S.A generated revenue of €231M at a net margin of 18.0%. Revenue declined 44.9% year over year. It earns a return on equity of 15.6%. Net debt stands at €154M. Fundamentals as of Jul 17, 2026
Our scenario range runs from €20.67 (bear case) to €37.71 (bull case); at €16.50, the current price sits below that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 17% below its 52-week high and 50% above its 52-week low, currently above its 200-day average. For context, the median of 10 Real Estate peers we cover trades at -2% fair-value upside, at 83%, ISUR screens cheaper than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
All 16 models by family
Widest divergence: DCF Models (€32.02) versus Dividend Discount (€6.19). Highest evidence: Growth DCF (80).
