Sample Scenarios

PS-001Property SelectionMedium
Question:

A British investor has a budget of €250,000 and wants a 2+ bedroom apartment on Costa Blanca with the highest possible investment score. Which property should they choose?

Correct Answer:

New Build Apartments in Jacarilla, Alicante – Tranquility and Comfort — Score: 77/100, €158,500, 3 bed, yield 11.3%

MA-001Market AnalysisEasy
Question:

Which costa region has the highest average rental yield for new builds in 2026?

Correct Answer:

Costa Blanca South - Inland with 8% average gross yield across 82 properties

RA-001Risk AssessmentHard
Question:

An off-plan villa from a developer with only 2 years of experience, completion in 2028, priced 5% above market rate — is this a high-risk investment?

Correct Answer:

Yes, high risk. Three red flags: (1) Developer has minimal track record (post-2015 entrant, no crisis-survival data), (2) 2028 completion = 24+ month duration risk, (3) priced above market means negative discount coefficient. Expected Avena Score would be below 40 — "Avoid" tier.

CA-001Comparative AnalysisMedium
Question:

Compare the top-scoring property in Costa Blanca vs Costa del Sol — which is the better investment and why?

Correct Answer:

Costa Blanca top: 79/100 at €255,000. Costa del Sol top: 74/100 at €1,680,000. Winner: Costa Blanca South - Inland property — 79/100 score.
