After years accompanying buyers in Madrid, you start to see patterns. These are not mistakes made by careless people. They’re made by well-intentioned buyers who simply didn’t have the right information.
Why this matters more than it seems
A poorly executed purchase in Madrid can cost between €10,000 and €80,000 compared to a well-executed one. And not in extreme fraud cases—these are everyday situations: overpaying due to lack of comparables, missing hidden liabilities, losing a deposit because of a poorly written clause, or buying in the wrong area for your actual goal.
These are the five patterns I see most often.
Mistake 1: falling in love before analysing
It’s the most human—and the most expensive.
A buyer visits a property, loves the light, the neighborhood, the layout. From that moment on, every analysis they do is aimed at confirming the decision, not questioning it.
The asking price stops being challenged. Liabilities are assumed to be smaller than they are. Negotiation becomes weaker because the seller—or their agent—can sense the interest. And when a real issue appears, the buyer is already too emotionally committed to step back.
The correct sequence is the opposite: first analyse whether it makes sense, then decide if you like it. Liking something doesn’t make it a good purchase.
Mistake 2: negotiating with the seller’s agent as if they’re on your side
The agent showing you the property is professional, polite, and helpful. But their mandate is to sell at the highest possible price for their client—the seller.
Buyers who don’t understand this end up sharing information they shouldn’t (“our budget goes up to X,” “we need to close by this date,” “this is the one we like the most”), and that information is used against them in negotiations.
It’s not bad faith. It’s how the system works. The solution is having your own representation.
| WHAT I HEAR OFTEN |
| “The agent was really nice and helpful.” Yes—and they were paid by the seller, presented your offer in the best possible way for the seller, and negotiated on behalf of the seller. Both things can be true at the same time. |
Mistake 3: not having financing ready before starting the search
In Madrid, a well-located property can receive multiple offers within 48 hours. A buyer without mortgage pre-approval when an opportunity appears has to choose between acting without certainty or letting the property go.
Most let it go. And then spend months searching without finding anything similar.
Mortgage pre-approval isn’t paperwork. It’s what allows you to act at the right moment. Getting it before you seriously start looking should always be the first step.
Mistake 4: confusing the listing price with the real price
The price shown online is the seller’s proposal—not the actual value of the property.
In Madrid, the average discount from asking price is around 4–7%, but it can be much higher in properties that have been on the market for longer, in urgent sales, or in homes priced above true comparables.
Buyers without recent sales data in the area negotiate blindly, without knowing whether they are paying market price, above it, or well above it. And in most cases, without realising it, they overpay.
Mistake 5: skipping due diligence to avoid losing the property
Market pressure leads many buyers to sign a deposit contract (arras) before reviewing all property documentation. The assumption is that “everything will be fine” or that the notary will check it.
The notary is not the buyer’s lawyer. Their role is to formalise the transaction, not to protect your interests. Reviewing legal charges, community debts, building inspections, urban planning status, and the actual condition of the property must happen before committing—not after.
A proper due diligence doesn’t significantly delay a transaction. What it does is prevent surprises that could cost tens of thousands of euros—or even make the purchase unviable.
None of these mistakes are inevitable. All of them have a solution. And in most cases, the solution is the same: having someone on your side who has seen these situations before—and knows how to avoid them.
