Recently, there have been more and more posts in online forums about life planning, and a few friends and I have started thinking about buying a house. But when it comes to the crucial topic of money, especially the down payment, everyone seems to have a different story. Some say 20%, others say it’s over 30%, which left me a bit confused. So, I took some time to do my research and have compiled what I’ve learned to serve as a reference for other members who are also considering it.

The Basic Components of a Down Payment: It’s More Than Just 20% of the Property Price
The common “20% down payment” figure you often hear is only half the story. Typically, a bank will only grant a mortgage for up to 80% of the property’s purchase price or its appraised value, whichever is lower. The remaining 20% is the “down payment” we need to cover ourselves. But, don’t forget, in addition to this 20%, there’s a significant amount of hidden “expenses” waiting for us: various taxes and fees.
These costs add up to roughly 10%-15% of the property price, depending on the autonomous community where the property is located and its price. They mainly include:
- Property Purchase Tax: For resale homes, this is the Property Transfer Tax (ITP); for new homes, it’s VAT (IVA) plus Stamp Duty (AJD). The ITP rate varies by region, generally between 6% and 10%.
- Notary Fees: The cost for notarizing the property transaction.
- Property Registry Fees: The fee for registering the property ownership with the government.
- Bank Appraisal Fee: The cost for the bank to send an appraiser to determine the property’s value.
- Gestoría Fees: Fees for the administrative agency (gestoría), hired either by the bank or by you, to handle the paperwork.
Therefore, a more realistic calculation is: Total Cash Needed ≈ 20% Down Payment + 10-15% for Taxes and Fees. This means it’s safer to have at least 30%-35% of the property price available in liquid funds.
A Simple Example
To make it clearer, let’s use a table to do the math. Suppose we’re interested in a resale property priced at €250,000, and the bank agrees to finance 80%:
| Item | Estimated Amount | Source of Funds |
| Property Price | €250,000 | - |
| Bank Mortgage | -€200,000 | Bank |
| Down Payment to be Paid | €50,000 | Buyer’s Savings |
| Taxes and Fees | €30,000 | Buyer’s Savings |
| Total Cash Needed | €80,000 | 32% of Property Price |
As the table clearly shows, to buy a €250,000 property, the initial capital we need to prepare is €80,000, not the €50,000 we might have initially thought. This is a significant difference that could easily disrupt your plans if not calculated beforehand.
Are There Any Exceptions?
Of course, there are some special cases. For example, for young people under 35, some banks or government programs may offer mortgages up to 90% or even 95%, which can significantly reduce the down payment pressure through home-buying benefits. Additionally, individuals in stable jobs like civil servants or those with very high, steady incomes might be able to negotiate better mortgage terms. Another possibility is purchasing a bank-owned property; banks sometimes offer 100% financing on these, but such properties often have less desirable locations or conditions and require careful evaluation.
Buying a house is a major life event, so it’s crucial to calculate the finances over and over. This is just my research based on the general situation; everyone’s financial status and the bank they deal with will be different. I hope this post helps clarify things and saves you some trouble. I welcome veterans who are currently applying for a mortgage or have already successfully bought their homes to add their insights and share their experiences! Let’s all work towards it!
