Every week the same question appears in the expat groups: "The villa costs 500,000. What will I actually pay?" And every week the answers range from "about 8%" to "at least 15%", which helps nobody. After 25 years and more than 500 sales on the Costa Blanca North, here is the full answer, line by line, with nothing left out.
The short version: plan for 11 to 12 percent on top of the price for a resale, and 13 to 14 percent for a new build. If your budget only works when the costs come in at 8 percent, your budget does not work.
How much should I add on top of the asking price?
Almost all of the extra cost is tax, and tax is not negotiable. In the Valencia region, which covers the entire Costa Blanca, the numbers break down like this:
- Resale property: 10% transfer tax (ITP), plus roughly 1.5 to 2% in professional fees and formalities.
- New build from a developer: 10% IVA plus 1.5% stamp duty (AJD), plus the same fees. Call it 13 to 14% in total.
One important nuance: the Valencia region introduced an increased ITP rate of 11% for high-value purchases above one million euros. If you are buying in that bracket, have your lawyer confirm the current rate and how it applies before you calculate anything.
What does a resale purchase cost, line by line?
Here is a realistic breakdown for a 500,000 euro resale villa, bought without a mortgage. The ranges are honest; the exact figures depend on the notary's fee scale, the complexity of the deed and which lawyer you choose.
| Cost item | Basis | Typical range | On 500,000 EUR |
|---|---|---|---|
| ITP transfer tax | 10% of price or reference value, Valencia region | Fixed by law | 50,000 |
| Notary | Official fee scale | 0.1 to 0.3% | 900 - 1,500 |
| Land Registry | Official fee scale | Roughly half the notary | 600 - 1,000 |
| Independent lawyer | Market rate, ca. 1% plus 21% IVA | 1 to 1.5% incl. IVA | 5,000 - 7,000 |
| NIE numbers, power of attorney, sundries | Per person / document | Fixed fees | 300 - 700 |
| Total | ca. 11.4 to 12% | 56,800 - 60,200 |

Note the wording in the first row: 10% of the price or the reference value. I come back to this below, because it is the single most common unpleasant surprise.
What changes if I buy a new build?
On a new build you pay IVA (VAT) at 10% instead of ITP, and on top of that AJD stamp duty, which in the Valencia region is 1.5%. So the tax load is 11.5% instead of 10%, before the same notary, registry and legal fees.
Two practical differences matter more than the headline rate:
- IVA is paid to the developer with each stage payment, not in one sum at completion. Your cash flow planning must reflect that.
- Off-plan purchases need extra legal checks: bank guarantees on your stage payments, the building licence, and the developer's ten-year structural insurance. The tax is the simple part.
What if I need a mortgage?
Good news, for once. Since the Spanish mortgage law of 2019, the bank pays the stamp duty on the mortgage deed, plus the notary, registry and processing costs of the loan itself. What remains on your side:
- Valuation (tasacion): an officially certified appraisal, typically 300 to 600 euros at this price level.
- Arrangement fee: 0 to 1% depending on the bank; often negotiable, especially if you bring other business.
- Insurance: banks will price the loan better if you take their home or life insurance. Compare the total package, not just the interest rate.
Non-residents can generally borrow 60 to 70 percent of the valuation. That is a separate topic, but for cost planning it means your own funds must cover at least 30 to 40 percent plus the full 11 to 14 percent in costs.
What about moving the money from home?
This line appears on no invoice, which is exactly why it costs people so much. If you transfer 500,000 euros from a Swiss, British or Scandinavian account, your bank will typically take 2 to 3 percent through the exchange rate margin. A specialist currency broker does the same transfer for 0.3 to 1 percent.
On half a million, that difference is 5,000 to 12,000 euros. It is often the largest single saving available in the whole transaction, and it takes one afternoon to arrange. Eurozone buyers can skip this section with a smile.
What does the seller pay, so I don't pay it twice?
Knowing what is not your cost matters just as much:
- Agency commission: paid by the seller on the Costa Blanca, typically 4 to 5% plus IVA. If an agent asks you, the buyer, for commission on a normal sale, ask why.
- Plusvalia municipal: the town hall's tax on the increase in land value. By law this belongs to the seller.
- Capital gains tax and mortgage cancellation: the seller's problem, including the registry cancellation of any old mortgage.
- The 3% retention: if the seller is non-resident, you withhold 3% of the price and pay it to the tax office against their capital gains liability. It comes out of their money, not yours, but the filing obligation is yours. Your lawyer does this as standard.
Which surprises catch buyers out?
Four situations produce almost all the bad stories I hear:
- The reference value (valor de referencia). Since 2022, transfer tax is calculated on the official reference value of the property if it is higher than your purchase price. Buy a well-negotiated bargain at 450,000 with a reference value of 520,000, and you pay ITP on 520,000. Always check the reference value before signing; it takes your lawyer ten minutes.
- Community debts. In a community of owners, the property itself answers for unpaid fees from the current year and the three preceding years. Never complete without a debt certificate from the community administrator. This is a standard document; a seller who resists producing it is telling you something.
- Plusvalia shifted by contract. The law puts plusvalia on the seller, but private contracts can shift it, and some developers and sellers quietly do. Read the clause. If it has been moved to you, that is a price increase in disguise and belongs in the negotiation.
- Unpaid IBI. Outstanding annual property tax attaches to the property. Your lawyer should confirm it is paid up and agree the proration for the current year in writing.
None of these are reasons to fear buying here. They are reasons to budget properly, use an independent lawyer who works for you and nobody else, and treat any "all in, about 8 percent" estimate as the sales talk it is. Plan for 12 percent on a resale and 14 percent on a new build, and the only surprises left will be pleasant ones.
