Buying an off-grid property in Spain

Start here: buying off-grid property in Spain

Most of the expensive mistakes in off-grid Spain happen before the keys change hands. The house is lovely, the view is perfect, and nobody mentions that the extension has no licence, the well isn’t registered or the track floods every winter. This page is the order I’d do things in, with the guide to read at each step.

1. Understand what “legal” means on rustic land

A country house can be in the Catastro, have a meter on the wall and pay its IBI every year and still not be fully legal. Start with legalising a rustic house (AFO and DAFO), then what you can build on rustic land. Together they explain why the age of a building, the category of the land and the region all matter.

2. Know your region

Planning law, purchase tax and even the number of solar panels you need change from one region to the next. In the Valencian Community there’s no time limit on the council’s action against unlicensed building on rustic land; in Andalucía there usually is. Purchase tax on a resale house runs from 7% in Andalucía to 10% or more in Catalonia. The region guides set it all out:

• Andalucía
• Valencian Community
• Murcia
• Castilla-La Mancha
• Catalonia
• Galicia
• Extremadura

3. Check the land before the house

My checks before buying rural land walk through planning, the Land Registry and Catastro, access, water, flood and fire risk. The cheapest check of all is the cadastral reference; four ways to find it takes five minutes. Then look up mobile coverage on the 4G coverage map if you need to work from home.

4. If it’s a ruin, slow down

Ruins are where the dream and the paperwork collide hardest. Read buying a ruin, step by step before you make an offer, and what it costs to rehabilitate one before you agree a price.

5. Budget for the systems, not just the house

A house with no grid, mains water or sewer needs all three replacing. As a rough guide from the prices on this site: an off-grid solar kit with a 9.6 kWh lithium battery costs about €3,600–€3,700 for the equipment, a fitted rainwater tank €1,500–€7,000, and a septic tank €900–€5,000 for the tank alone, with fitting and licences on top. A borehole adds €1,800–€15,000. Then there’s the running cost, which first-year costs of living off-grid adds up, and my honest account of what it really cost us.

The people you’ll need

For most purchases you’ll want three professionals, and they do different jobs:

• A property lawyer checks title, debts, charges and the contract, and puts conditions in it so you can walk away if the paperwork fails. Find one who does rural conveyancing, not just apartments.
• An architect or technical architect compares what’s built with what’s registered and licensed, and tells you what it would take to regularise it.
• A surveyor or builder you trust looks at the roof, walls, damp and services.

Conveyancing lawyers rarely visit the property, so the architect’s site visit matters. Our directory lists property lawyers and builders and architects who work on rural property.

The mistakes I see most

• Trusting “no pasa nada”. Believe paper, not people. A town hall resolution with a date and file number beats any reassurance.
• Paying the deposit first and checking later. Do the cheap checks before the deposit contract, and make the deposit refundable if they fail.
• Forgetting the track. If a delivery lorry, septic truck or fire engine can’t reach the house after rain, you have a problem. See nobody mentioned the driveway.
• Underestimating water. A dry or unregistered well changes the whole budget.

I’m not a lawyer, and none of this is legal advice for a particular property. It’s the order of questions I wish I’d asked before we bought our finca.
