REAL ESTATE DUE DILIGENCE: BUY OR SELL YOUR PROPERTY

WHY REVIEWING YOUR PROPERTY DOCUMENTATION IS ESSENTIAL BEFORE BUYING OR SELLING A PROPERTY

In today’s competitive real estate market in the Costa Blanca, especially in areas like Altea, international buyers expect transparency, legal security, and clarity.

A beautiful property is no longer enough. Buyers want guarantees.

This is where real estate due diligence becomes essential.

At ALTEAINVEST, we help property owners prepare their homes for sale by identifying and resolving legal and urban planning issues in advance and ensuring a smooth, secure, and successful transaction.

WHAT IS REAL ESTATE DUE DILIGENCE?

Real estate due diligence is a comprehensive review of a property’s legal, administrative, registry, and urban planning status.

This process allows us to detect potential issues such as:

Outstanding debts or charges on the property (sometimes unknown to the owners)
Lack of the necessary documents to complete the sale
Discrepancies between Land Registry and Cadastre
Undeclared constructions or extensions
Urban planning irregularities
Legal limitations affecting the sale

By addressing these issues early, you avoid delays, renegotiations, or even losing serious buyers.

COMMON PROBLEMS WHEN BUYING OR SELLING PROPERTY IN SPAIN

Many homeowners—especially international owners—are unaware that their property may have legal or urban planning issues.

At ALTEAINVEST, we frequently encounter:

1. Registry and Cadastre discrepancies

Differences in built area or unregistered modifications can create complications during the sale process.

2. Undeclared works or extensions

Swimming pools, terraces, or additional rooms not legally registered can delay or block a transaction.

3. Urban planning issues

Properties classified as out of planning or located on non-urban land require expert analysis.

4. Missing key documentation

Building permits, habitation certificates, or proof of property age are often required by buyers and notaries.

NOT ALL REAL ESTATE AGENCIES OFFER TRUE DUE DILIGENCE

While many agencies in Altea and across the Costa Blanca focus primarily on marketing and sales, not all are equipped to carry out a thorough legal and urban planning review of a property.

Identifying potential issues is already complex—but resolving them requires specialized knowledge in legal, registry, and urban planning matters, as well as experience dealing with local authorities and technical professionals, and unfortunately most estate agents in Altea and along the Costa Blanca lack this kind of experience and expertise, and are not even able to identify potential issues that could prevent or hinder the sale of a property..

For international sellers, this difference is critical. Choosing an agency without this expertise can lead to delays, failed transactions, or unexpected complications at the final stage.

At ALTEAINVEST, due diligence is not an add-on—it is a core part of our service. We've been doing this for over 45 years.
