Buying a house blends emotional choices with legal, fiscal and technical obligations, and a clear sequence of checks reduces the chance of costly setbacks. This article outlines a practical route through the process so you can make informed decisions at every stage. You will find concrete
advice on which documents to obtain, which contractual clauses matter most and which professional steps help prevent unpleasant surprises before the transfer of title.
Think of the purchase as a chain of linked steps: searching and negotiating, submitting a formal offer with a deposit, signing the preliminary contract, arranging the mortgage and finally completing the notarial deed. Skipping a verification can stop the whole transaction. Early checks such as the land
registry extract, the energy performance certificate and an urban conformity check are essential because irregularities or hidden liens may make the sale impossible or far more expensive.
Initial checks and technical due diligence
Before committing, obtain formal documentation that proves ownership, the absence of burdens and the building’s legal status. Request the land registry extract to confirm the seller and reveal any mortgages or attachments. Ask
for the energy performance certificate to assess likely operating costs. Verify that the physical layout matches the cadastral plans; differences between the actual property and the planimetry can block financing or the closing. Also confirm that any renovations were authorized: an unregularized extension or an illegally closed balcony may force expensive remedies or prevent the deed.
Key documents to request
Compile a packet including the land registry extract, the energy certificate, the building’s planimetry and permits for any modifications. Add a mortgage search to detect financial encumbrances and, where applicable, condominium minutes to identify pending works or special assessments. Cross-check that the property description in public records corresponds with what you see on-site. These verifications reduce the risk that a later discovery — such as a hidden lien or a missing habitability certificate — will derail the transaction or force large, unplanned expenses.
Negotiation, proposal and deposit
When you reach an agreement on price, decide how to formalize the commitment. A written offer to purchase is typically a unilateral act that binds the buyer for a set period while the seller considers acceptance. At that stage a deposit — commonly between 5% and 10% of the price — is expected. Negotiation power and a calm approach to the price can prevent overpaying. Understand the legal impact of any advance payment and never sign without checking the related clauses and timelines carefully.
Types of deposits and contractual protections
Not all deposits work the same. A confirmatory deposit is a stronger guarantee: if the seller withdraws, they must return double the amount; if the buyer pulls out, the seller can keep the sum. A penitential deposit functions as a purchase-withdrawal fee, allowing either party to exit by paying or forfeiting the agreed amount. In the preliminary contract, always request a suspensive clause for mortgage approval so you are not bound if the bank refuses financing. After signing the preliminary, register it within the statutory deadline to formalize obligations and protect your position.
Registration, transcription and costs
Once the preliminary pact is signed, registration at the tax office is mandatory within the legal window and involves a fixed registration fee plus stamp duties; in many systems there is also a percentage applied to the confirmatory deposit, which may be credited at closing. Transcription of the preliminary in the property registers is optional but advisable when the seller could be exposed to creditors or may sell the asset again: it protects your right against third parties. Anticipate additional notarial and registration costs, which are an investment in legal certainty rather than mere overhead.
Mortgage, appraisal and notarial closing
Start the mortgage procedure early: the lender orders an appraisal to confirm the property value and decides whether to fund the loan. If the appraisal is below the agreed price you will need to provide extra equity. Ensure there are no cadastral or regulatory discrepancies that could block disbursement. Choose between fixed and variable interest rates based on your risk tolerance and explore public support schemes, such as government guarantee funds for young buyers, where eligible. On the day of the notarial deed the notary validates documents and executes the transfer: at that moment ownership becomes official. If you used an agent, remember that commissions are often negotiable, so clarify fees in advance to avoid surprises.
