A specialist approach.
Jason’s career spans more than 15 years across international hospitality and residential property, providing a background centred around client service, sales and working with an international clientele.
Now based in Marbella, Jason founded Jason Callow Homes with a clear focus on one particular area of the Costa del Sol property market: new-build and off-plan homes.
Rather than operating as a traditional general estate agency, Jason has developed the business around specialist knowledge of new residential developments, working across multiple developers and locations to help clients compare the opportunities available throughout the market.
Today, Jason Callow Homes works with buyers from around the world, with recent clients from across Europe, the United Kingdom, United States, Canada and the UAE.
SPECIALIST IN NEW AND OFF-PLAN PROPERTY
An exciting segment of the market.
Jason has developed a particular specialism in the new-build and off-plan property market across Marbella and the Costa del Sol, working closely with many of the region’s leading developers and residential projects.
His knowledge extends beyond individual properties to the wider new-development market, including locations, pricing, specifications, construction stages, completion timelines, amenities and the differences between competing developments.
By following new project launches, availability and price changes across the market, Jason is able to help clients compare opportunities across multiple developers and locations rather than considering a single development in isolation.
From contemporary apartments and penthouses to private villas, gated communities, resort properties and branded residences, Jason’s approach is centred around understanding each client’s requirements and identifying the developments that offer the strongest match for their lifestyle, budget and objectives.

CLIENT TESTIMONIAL
Luxury Villa in Benahavis.
We first met Jason earlier this year when we started our search for a property in or around Marbella. From the start he was everything you absolutely hope a property agent to be yet sadly, in this day and age, rarely experience.
To begin with he was extremely helpful, he listened to everything we wanted and showed us exactly what we asked to view in the price bracket we signalled. There is no “sales fluff” with him. He gives his honest and professional opinion when asked which comes across as measured – something only experience and a market wisdom brings. I’m a person who likes to do his due diligence so it was so comforting to hear an array of people in the trade speaking so highly of him. Once we landed on the house we wanted, Jason went above and beyond – even helping to manage negotiation meetings and since then has been the keystone to our entire project.
He manages the developer, the lawyer, the designers, the architects! It’s the search-to-contract-to-keys full service and we definitely wouldn’t be able to even consider this house purchase without him. Sitting here in the UK, trying to buy a house in Spain brings a myriad of stresses and concerns born through a complete ignorance of the process. However, Jason has been a shining light of knowledge throughout. We cannot recommend him highly enough.
CLIENT TESTIMONIAL
New Build Penthouse in Marbella.
Living in CA for most of my life, I decided I wanted to purchase a property in Spain after visiting on vacation. After several weeks of research, I came across Jason Callow online. His professional website caught my eye, and his listings were exactly the type of property I was seeking. After inquiring, Jason promptly responded even with the time difference.
Since then, he has been extremely helpful and reliable in my search. After only a few short months, he was able to find me the exact property that I was looking for. His professionalism and resources are unparalleled. He walked me through the entire process seamlessly. I visited Spain to see the property and met Jason, he is incredibly kind and cares about his clients. I would highly recommend his services to whomever is looking for a property overseas.
I will be using him in the future for all of my endeavours and have already recommended him to several friends looking to purchase.
