Real estate agency
Luxury real estate in Madrid
Altium Properties is a boutique agency focused on Madrid's luxury homes. Less volume, more judgement: we guide every purchase and every sale with real knowledge of the prime market and absolute discretion.
What makes us different
Specialists in the most expensive square metre in Spain
We don't cover the whole city: we focus on Madrid's prime core —the Salamanca district, Chamberí, Retiro, Chamartín and the northern residential estates—. That focus is what lets us know every building, every entrance and the true value of each address.
A market that isn't on the portals
Much of Madrid's luxury market never gets published. We work an off-market portfolio and a network of qualified owners and buyers reachable only through direct relationships, not shop windows.
One point of contact, start to finish
The person who takes your first call is the same one who negotiates and signs before the notary. No chains of agents, no file hand-offs. Discretion and a direct relationship at every step.
Buying and selling under the same standard
We guide both those selling a distinctive home and those looking to buy one. Knowing both sides of the market is what lets us close deals that are fair to everyone.
Where we work
Every prime area of Madrid has its own market. These are the neighbourhoods we know inside out:
Frequently asked questions
Which areas of Madrid does Altium Properties cover?
We focus on Madrid's prime segment: the Salamanca district, Chamberí, Retiro, Chamartín, the historic centre and the northern estates such as La Moraleja and Aravaca. It's a deliberate focus: we'd rather know a few areas inside out than cover the whole city superficially.
What does a luxury real estate agency in Madrid charge?
In the premium segment, fees typically range between 3% and 5% of the sale price and are usually paid by the seller. The exact figure depends on the type of mandate, exclusivity and complexity of the deal. For buyer representation, a different structure can be agreed.
What is an off-market transaction?
It's the discreet sale of a home, without appearing on portals or with a sign. In Madrid's luxury market a very significant share of deals close this way. We work an off-market portfolio and a network of owners and buyers reachable only through direct relationships.
What sets a boutique agency apart from a property portal?
A portal is a shop window: it lists ads. A boutique agency like Altium curates, advises and negotiates with a single point of contact from start to finish. Less volume, more judgement and discretion at every step.
