Do you want a property that you can renovate and insure without any problems, but that can also be sold in the future?

First read here about the pitfalls and why an IGP inspection is so important

Buy safely? How…

The experiences of our members have led to a series of recommendations to steer the purchase of your property in the right direction. Buying a house in Spain should be a feast and not end in trouble and stress. Starting with the estate agent. He or she can never act for you and the vendor at the same time, although he or she will try to gain your confidence and give the idea to look after your interests. And because it is not paid by you, it is also impossible to hold him accountable in the event of problems.

The only professional who can actually and exclusively look after the interests of the buyer is a reliable architect specialized in urbanismo (zoning plans) who visits the property. A lawyer assumes a paper reality and that in Spain is, as the practice teaches very unwise. It is not the competence of a lawyer or estate agent to be able to assess whether a property is legal, illegal or can be legalized and whether the permits are (still) valid, the reason that so many transactions end with problems afterwards.

Casa Propia only works with architects who have signed our Declaration of Integrity and are supervised by the arbitration committee consisting of members of Casa Propia. Preventive measures to ensure that professionals do what you expect from them. You will not find this safety anywhere else!

Being able to sell in the future is not that self-evident

A property actually must already meet the standards so that you can renovate and insure without any problems, but you also want to be able to sell your property in the future. So the property must be future proof.

Anyone who wants certainty cannot be tempted to buy with arguments such as “this Spain, this it how it works“. As one of the few provinces in Spain, Catalonia has made a residence permit mandatory when selling a property. It is only logical that this condition will ultimately apply to the whole of Spain. This means that a huge number of properties that are now being bought and sold are unsaleable as long as illegal constructions (including time barred) has not been legalized or demolished. In fact, that determines the value of a property and may even determine your interest. Therefore always do the IGP inspection, because having a residence permit does not mean that it is also valid!

Found a property?

We guide you from A to Z

  1. We first make a pre-scan of the property to know if it is worth continuing the purchase process before incurring additional costs.
  2. We prepare the letter of intent. The document with which we reserve the property, but which indemnifies you if the property has problems, a clause in which the result of the IGP inspection is included as a resolutive condition.
  3. We coordinate the signing with the seller
  4. We prepare the deposit account with the notary
  5. We appoint a procurador who also works in court to collect all necessary documents for the IGP inspection
  6. We coordinate the gestor and the architect who perform the IGP inspection.
  7. Choose a lawyer, preferably recommended by Casa Propia, who has signed the integrity code to have the purchase agreement drawn up
  8. We coordinate the sending of the contract to the notary for the preparation of the deeds


  • Step 1


    The property is initially checked for legality using our schedule or an architect. There is verbal agreement between you and the seller, whereby a price and payment method have been agreed, as well as a possible delivery date.

  • Step 2


    Preferably do not sign a reservation contract or purchase agreement (opción de compra, contrato privado), but first sign a letter of intent with the help of lawyer who signed the IGP-integrity code, whereby you and the seller agree to complete the transaction. No risks and no major payments before you know whether the property is in order. And everything in your own languange!

    In the letter of intent, agreements are recorded and the independent IGP inspection is included as a resolute condition to protect you and the seller from problems afterwards. But also, for example, that the seller does not offer the house to third parties during the agreed period and that you do not unnecessarily incur thousands of euros in lawyers’ fees for a house that appears to have unsolvable problems.

    After signing the letter of intent, you will deposit an amount in deposit into an independent third-party account (not the real estate agent or lawyer), an amount agreed with the seller. This deposit is deducted from the purchase price if the purchase takes place, and is refunded if the IGP inspection turns out to be negative and you cancel the purchase.

    Step 2

  • Step 3


    The property is checked according to a fixed format for the most important aspects (more info) by a gestor and an architect who checks the house on location. The findings are recorded in a document that you can also use for a second opinion if desired. The document is stored by the IGP for your security to ensure that professionals do the work they are expected to do. They have all signed the integrity statement and are supervised by the arbitration committee consisting of Casa Propia members.

  • Step 4


    Now it is time to give the purchase legal form in a purchase contract. IGP only works with lawyers who have signed an integrity code, use the model contracts of IGP and work under the supervision of the arbitration committee. This prevents errors and you also have everything in your own language!

    Step 4

  • Step 5


    In Spain the payment is made at the time of signature at the notary before the registration in your name in the so-called Registro Propiedad. This means uncertainty lasts for a few months unforeseen events could occur that delay the registration or even make it impossible. For example unwanted adjustments at the expense of the buyer, who although having paid is only the owner on paper and therefore cannot exercise owner’s rights, with all the consequences that entails.

    IGP therefore always recommends using the secure payment method, whereby the money is held in a notarial account or an independent bank deposit and only released under the condition that the property is registered in Registro de Propiedad in your name subject to the agreed conditions. In case of a positive inspection it might not be necessary. Discuss it with the gestor, architect and lawyer involved.
