Independent advisory, built around your interests.
We are not a mass-market brokerage. We are a focused advisory firm representing buyers and sellers on the Costa Blanca — with objectivity, discretion and a long-term view.
Analysis first, then the recommendation.
MARNER ESTATES operates at the intersection of brokerage execution and strategic advisory. We are not tied to developers or sales quotas; our role is objective guidance, market intelligence and risk-aware strategy — tailored to your goals.
Whether you are acquiring, structuring or selling, every recommendation is grounded in data, due diligence and long-term planning.
“Every recommendation is driven by analysis, not sales pressure — aligned solely with your goals, on either side of the table.”
Marcel Fichtner founded MARNER ESTATES to represent investor and owner interests rather than developer sales targets, working with international clients across the Spanish market. The firm focuses on strategy, discretion and long-term value. Your contact for the Costa Blanca is Ion Postolache, Sales Director of MARNER ESTATES, who advises in Spanish and English.
A clear advisory mindset.
Independent
Investor- and owner-focused guidance — never a developer sales channel.
No mass market
Selective mandates and quality over volume, on both the buy and the sell side.
Transparency
Clear communication and data-backed reasoning at every stage.
Discretion
Private, confidential handling — from valuation to closing.
Cross-border practice
Buyers and sellers who are not resident in Spain, and the questions that come with that.
Long-term view
Strategy aligned to appreciation, income and exit — not a quick transaction.
