§ 1The lagoon

The Mar Menor is a shallow lagoon in the Region of Murcia, separated from the open sea by a long sand strip. Resorts, ports and urbanisations stand around it, and it is known for calm warm water. This page belongs to the chapter on Costa Cálida property prices.

§ 2The market

The registry reports that foreigners made up 23.71% of home purchases in the Region of Murcia in the second quarter of 2026. We found no official average for the Mar Menor area, so we print none. The stock mixes apartments, townhouses and villas, much of it resale. Compare by urbanisation and age.

§ 3Taxes

The Ministry of Finance table of September 2026 gives the Murcian general resale rate as 7.75% since 25 July 2025. An undated regional FAQ still shows eight per cent. Confirm the rate on your deed date. The costs section explains.

§ 4Flood level

The area is low and flat. The weather agency reported 771.8 mm on the calendar day at one station in the October 2024 storm, and flooding that reached coastal towns. Check the national flood viewer, the ground-floor level, garages and drains, and ask neighbours. The location checks section explains.

§ 5Coastal law

Homes near the shore are subject to the coastal law, which protects a zone of 100 metres inland from the shore, with a further influence zone. Ask your lawyer and the coastal service for the certificate described in the ministry FAQ.

§ 6Environmental limits

The lagoon has environmental protections and problems. We did not read the technical reports or the planning limits, so ask the town hall in writing whether any restriction affects the plot.

§ 7Communities and licences

Many homes sit in communities with shared pools. Ask for the statutes, accounts, minutes and reserve fund, and check the licences of extensions with the town hall and your lawyer.

§ 8Tourist lets

Tourist lets in Murcia are regulated by the region, with municipal planning and community statutes on top. We did not read the regional decree in full, so ask a local lawyer. A three-fifths vote of all owners can approve, limit or ban lets in a community.

§ 9Who it may suit

It may suit buyers who want calm water, flat terrain and a leisure setting. Buying in Murcia city covers Murcia city inland.

§ 10What we could not verify

We found no official average for the area and did not read the environmental reports or the municipal rules.

§ 11Questions to ask on site in this place

Ask about the level of the ground floor, the drainage and the licence of any extension. Ask the community administrator, if there is one, for the statutes, the last accounts and the minutes of the previous meetings. Visit in summer and after a storm, because heat and flooding are the two seasons that test a home. Write down the answers and compare them with the documents your lawyer receives from the registry and the town hall.

FAQRelated questions

What is the Mar Menor?

A shallow coastal lagoon separated from the Mediterranean by a strip of land, with towns and urbanisations around it. It is popular for its calm water, and it has had environmental problems, which we did not research in detail.

Does flooding matter here?

Yes. The area is low and flat, and heavy rain can flood roads and ground floors. Check the national flood viewer, the level of the home and the drainage, and ask neighbours about past episodes.

Is the coast protected?

The coastal law protects a strip inland from the shore and limits building there. Ask your lawyer and the coastal service whether the home lies in it and obtain the certificate the ministry describes.
