A good real estate agent in Madrid can save you time, money, and stress—but a poor agent can cost you. In this article, we explain how to choose the right professional. Look for agents with proven local experience in the neighborhoods you’re targeting, clear fee transparency, and strong communication. Ask how many similar properties they’ve closed, whether they support negotiation, and how they verify legal status and property debts. Red flags include vague pricing guidance, pressure tactics, unclear commissions, or lack of documentation. Whether you’re buying, renting, or investing, your agent should support you with property comparisons, realistic pricing, and full clarity around contracts. For foreigners and expats, bilingual support is a major advantage.
