A licensed, locally-based international real estate agency — with a decade of experience helping buyers find their place in the sun.
We are a locally-based international real estate agency on the Costa Blanca, led by owner-entrepreneurs since 2014. Initially operating under the marketing name Grupo Mercal from 2014 to 2019, we joined the Sp-Koti network in autumn 2019 as the chain's first international franchise.
Our company, Seili Investment, S.L., is registered in Spain and fully authorized by the Valencian Autonomous Community. We adhere strictly to local legislation, regulations, and established business practices — giving our clients complete peace of mind throughout the buying process.
We offer a smooth and comprehensive turnkey service for real estate transactions, with excellent aftercare included. Many of our clients find their perfect home through our purchase mandate service — a generally free buyer service where we search for properties that fit within your budget and meet your needs, whether it's a city centre apartment, a terrace house near the Mediterranean, or a private villa in a golf resort.
Costa Blanca, located within the province of Alicante in the Valencian Autonomous Community, is a stunning 200-kilometre stretch of coastline — from Denia in the north to Pilar de la Horadada in the south. With around 2 million inhabitants in the Alicante region, it is one of Europe's most popular destinations for both tourism and permanent relocation.
The southern part, known as Vega Baja, is particularly notable — with Torrevieja as its largest city and popular areas including Orihuela Costa, Santa Pola, Guardamar del Segura, and Pilar de la Horadada. The area attracts Spanish and international buyers alike, drawn by the climate, infrastructure, golf courses, and excellent value for money.
