Why a home sale falls through before the notary: 5 deal-breakers

There is a stretch of the buying process where more deals die than anywhere else: the weeks between signing the arras (the deposit contract) and the deed before the notary. The price is agreed, hands have been shaken, and still the sale falls through.

From this side of the table you can see it coming. There are signals: deadlines that stretch, calls that go unreturned, a document that is always missing. These are the five reasons a home sale in Alicante breaks before it reaches the notary, and what a good agent watches to keep it alive.

1. The financing that never arrives

It is the number one cause. The buyer signs the deposit trusting a mortgage that is not yet approved, and the bank says no. Or it says yes, but for less.

The quiet problem is the valuation. The bank does not lend against the price you agreed, but against the value its appraiser assigns to the home, and it usually finances 80% of that figure. If you agree on 200,000 € and the official valuation comes in at 180,000 €, the bank lends 80% of 180,000, that is 144,000 €. The gap up to the price, 56,000 €, comes out of your pocket. Many buyers with just enough savings discover that hole halfway through and can no longer close it.

There is a defense, and it is called the financing condition (condición suspensiva de financiación): a clause in the arras contract stating that if the bank denies the loan and you prove it in writing, you recover the deposit without penalty. Without that clause, losing your mortgage can cost you the deposit. Before signing anything it helps to know what each bank lends and on what terms.

2. The nota simple that hides something

The second sale that falls through is the flat that was not as free as it looked. A nota simple from the Land Registry, ordered in time, costs a few euros and reveals what the seller does not always mention: a lien, a lifetime usufruct in favor of a relative, an inheritance not yet divided among siblings, a mortgage still alive.

Sometimes the surprise is not in the Registry but in the building community: an approved special levy of 8,000 € for the lift, unpaid back fees, or an extension built without a permit that does not match the cadastre. Any of those can stop the deal cold while it is sorted out, and sometimes it is not sorted out. Checking the charges before you buy is not distrust, it is routine.

3. Cold feet, and what they cost

Sometimes it is not the paperwork that fails: it is the stomach. The buyer falls for another flat, the seller gets a better offer, or the doubt simply arrives at three in the morning. This is where the type of arras signed matters.

Penitential arras, governed by article 1454 of the Spanish Civil Code, let either party walk away without explanation, but at a price. If the buyer backs out, they lose the deposit handed over. If the seller backs out, they return it doubled. It is a right to change your mind, not a breach: no one can force the other to sign the deed, only collect the penalty. And it is not loose change: the deposit is usually around 10% of the price, so on a 250,000 € home there are 25,000 € on the table. Knowing whether your arras are penitential or another type completely changes what you are risking.

4. The chain that breaks

Many purchases depend on a sale. The buyer needs to sell their current flat to raise the money for the new one, and if that first sale is delayed or collapses, it drags the second one down. It is the domino effect of every property chain.

There are ways out. A bridge mortgage lets you buy before you have sold, giving you a window (usually 12 to 24 months) to place the previous home without drowning. It is not for every budget, but knowing that the bridge mortgage exists keeps a tense chain from snapping at its weakest link.

5. The papers that do not match

The last group is discrepancies. The cadastral surface does not match the Registry. There is work (a pool, an enclosed porch, a converted attic) that was never declared. The energy performance certificate is missing, or the building's technical inspection has expired.

None of these is necessarily serious, but each adds weeks of paperwork, and deals have an emotional expiry date. When the signing is postponed again and again, one of the two parties eventually lets go of the rope.

What a good agent sees coming

Almost all of these breakups announce themselves. A buyer who avoids talking about their mortgage is usually a buyer without financing closed. A seller who cannot find the nota simple usually has something they would rather not show. A signing postponed twice rarely reaches a third.

The quiet work of an agency is to order the nota simple before the arras, check that the valuation keeps pace with the price, draft the financing condition when needed, and sequence the deadlines so the chain does not tighten. It is not magic: it is getting ahead. That is why homes that reach the market well prepared, like this penthouse in central Alicante, close without alarms.

The context does not reward improvisation either: in July 2026 notaries confirmed an 11.8% year-on-year drop in home sales, a sign of a slower, more selective market. In a market like this, the deal that is prepared beats the one that is rushed.
