Mare Nostrum Inmobiliaria

Mare Nostrum is an estate agency based in Frontera, in the El Golfo valley, from where it covers all three municipalities of El Hierro: Valverde, Frontera and El Pinar. Its portfolio mixes homes in the island's villages with urban plots and rural land scattered across the interior.

Beyond brokering sales and rentals, the agency handles the surrounding paperwork: deed processing, mortgage arrangements, property management and valuations. That full-service approach is typical on small islands, where buyers often come from outside and need the whole transaction resolved in one place.

Dealings are direct and run from a physical office, which is not a given in a property market as small as El Hierro's.
