3-year capital gains prediction in InvestMap, powered by our predictive model with factor explainability.

Context and Problem

Projecting the capital gains of a zone relied on a mix of heuristics, manual comparables and expert judgment. This made projections hardly reproducible across analysts, hard to defend in committee and almost impossible to audit after the fact. Without a single, explainable model, it was difficult to prioritize zones in a systematic way and to communicate the thesis with confidence to the investor.

The Solution: Capital Gains Prediction with In-House Model

We added to InvestMap a 3-year capital gains predictive model, natively integrated in the zone page and built on top of the platform's centralized dataset.

• Quantitative prediction: the zone shows a 3-year capital gains projection along with the resulting €/m² price, with the model's precision metric clearly visible.
• Built-in explainability: breakdown of the main factors the model has used to justify the prediction (income variation, population, sale and rental prices), with their relative contribution.
• Always-fresh data: the prediction is recomputed on the latest InvestMap data, aligned with the rest of the views (supply, comparator, database).
• Source traceability: every prediction explicitly cites its sources (INE, PropHero model) to strengthen the case in committee.

Expected Impact

• Stronger investment theses: decisions rely on a single, reproducible model rather than manual exercises.
• Systematic zone prioritization: the team can rank and filter by expected growth in a consistent way.
• Higher committee confidence: factor-level explainability allows quick answers to questions about why a projection is what it is.
• Foundation for new models: this first model paves the way for new predictions (rental, demand, risk) on top of the same infrastructure.
