Buying land starts with choosing a hypothesis, not believing a listing. A photograph can be appealing, the view can be real and the asking price can fit the budget. The questions that decide the purchase are usually elsewhere: in the property documents, the boundary you can identify, the municipal plan, access, and the written answer you receive when your plan depends on it.
This guide gives you an order of work. It does not replace a solicitor, lawyer, architect or technical professional. It helps you decide what to request first, which question each source can answer, and when it is worth spending more time or money.
Where to find land
Property portals are useful for finding opportunities from private sellers and professionals. Search more than one source, including Idealista and Imovirtual, and keep the same short record for every candidate. One portal may show an area, approximate location or sales claim that is absent from another. That difference is a reason to ask a question, not to select the convenient version.
Compare the parcel, not just the listing: stated location, area, price, date, tax or registry identifiers when supplied, ruin, project, water, electricity and access. A portal is an entry point. The decision starts only when those claims can be connected to the property, its boundary and official sources.
Before visiting
Open the listing and make a short record: link, date, asking price, stated location, advertised area and every statement that could change your decision. You are not trying to reach a conclusion yet. You are preventing information from disappearing if the listing changes or is removed.
Write down your intended use as well. “I want land” is too vague to guide due diligence. A plan to rehabilitate an existing structure, run agricultural activity or compare two parcels produces different questions. In the first conversation, ask for identifiers before promises: parish, tax reference, registry description or a certificate access code, where the seller can provide them. Ask for a current tax record, valid registry certificate, survey or plan. If there is a ruin, ask how it is identified in the documents. If water, electricity or drainage are mentioned, ask whether there is an actual connection, contract, meter or merely a nearby network.
Turn the listing into questions
A listing is a commercial lead, not a complete source of proof. Translate each claim into a question with a recipient and a document or confirmation attached.
| The listing says | Question worth asking | Where to look |
|---|---|---|
| “Urban land” | Which classification applies to this boundary and which rules explain it? | Current PDM, its rules and municipality |
| “With ruin” | What structure exists, how is it identified and what operation is intended? | Property documents, visit and professional |
| “Water and power” | Is there an existing connection, available capacity and legal access to make it? | Seller, utility operators and municipality |
| “Ready to build” | Which written decision supports that conclusion for my intended use? | Municipality and applicable process |
A parcel can be attractive without a verdict
Uma parcela, quatro perguntas
Leonor finds a listing for a fictional mainland parcel described as “urban land with an old structure, water and electricity”. The advertised area is 2,400 m². She wants to assess whether to make an offer to rehabilitate the structure.
Rather than asking for a building guarantee, she asks for the property identification, tax record, certificate code, recent photographs, location of the structure and access information. The tax-record area does not match the advertised area and the route used to reach the land crosses another property. The parcel may still be interesting, but it is no longer ready for a quick decision.
The lesson is not a verdict. Leonor has moved from “I like this land” to a list of facts that can confirm, limit or alter her plan. If the area, access or structure changes the purchase, she knows not to leave it implicit.
An order that avoids wasted work
First check that every source concerns the same property. Compare municipality, parish, tax reference, registry description where present, area and boundaries. The property-registry certificate shows current registrations and pending registration requests; the tax record describes tax and cadastral elements. They are not interchangeable documents. See the official IRN guidance on property certificates and the Tax Authority guidance on the tax record.
Then locate the available boundary. A map geometry helps orient the search, estimate an order of magnitude and identify which plan to consult. It does not settle a disputed boundary or replace legal identification. BUPi explains methods of identifying boundaries and the practical difference between cadastral municipalities and those using mapped graphical representation.
With a more reliable location, move to planning: obtain the current PDM, planning map, constraints map and regulations through SNIT or the municipality. Read them together. A colour on a plan without the rule that explains it leaves the question half answered. Then investigate what changes with your intended use: access, easements, water, drainage, electricity, telecommunications, risk, protected areas, RAN, REN and municipal processes.
Mistakes that cost time
Do not treat the advertised area as the area every document describes. The listing may cover part of a property, multiple tax references or a map estimate. Do not read “urban” as “I can build what I want”. Classification and applicable rules depend on the instrument, boundary and proposed operation.
A visit along a track does not automatically prove legal access. Seeing infrastructure nearby does not confirm capacity, cost, contract or connection feasibility. Mark each issue as confirmed, pending or contradictory. Confirmed should mean that you know the source and what it says. Pending means that information or a competent answer is missing; contradictory means that two sources say different things.
What to take to the next conversation
Before speaking to the municipality, a professional or the seller, take one page with the location, boundary used, documents received, intended use and the three questions that would change the purchase. In Leonor’s example, that is the two areas, the old structure and evidence of access. It creates a practical conversation rather than a generic one.
Local checklist
Before relying on a promise in the CPCV
0/6 checked on this device
When you have an approximate geometry, you can screen the parcel on the Terreno Claro map. Use the preview to organise the sources and next questions, never as authorisation to buy or build.
For a specific part of the work, read Can I build on this land?, the documents checklist before the CPCV, and when to consider a PIP.
Limit of this guide
It helps organise questions and evidence. It is not a licence, municipal decision, certificate, legal opinion or guarantee of outcome. Always confirm the current rules and competent authority for the specific case.
