A seller with a residence at €8 million above Benahavís asks how long it will take to sell, and there is a number waiting for them in a dozen market reports. There is no honest way to produce it. Days on market requires two dates — the day a residence came to market and the day it completed — and Spain releases the second nowhere at property level.
That is the whole of the problem, and it has no workaround. What the notaries and the land registry record reaches the public as district-level aggregates of declared values, months in arrears, with every class of stock averaged together. There is no public per-property completion date, and no per-property closing price to attach to one. No source, this desk included, can honestly quote how long a residence in the upper register takes to sell.
What the published figures are actually built from
The medians that circulate are assembled from portal listing feeds: the date a listing appeared, the date it disappeared. Four defects sit inside that method, and they do not cancel each other out.
A listing withdrawn and republished starts a new clock. The same villa marketed through four agencies produces four listing ages, none of which describes the residence. A disappearance can mean a completion, a withdrawal, a change of agency or a seller who has decided to wait, and the feed cannot tell them apart. The residences shown only by introduction never enter the count at all. Each of those defects pushes the apparent figure in the same direction, which is downward.
So the direction of the error is knowable even where its size is not, and there is no dataset against which to correct it. A published days-on-market median for a Marbella zone is not a measurement that came out slightly wrong. It is a reconstruction wearing the clothes of a measurement.
What listing age does show
Listing age is a different quantity, and a usable one, provided it is named accurately. It records how long a price has been visible — not how long a sale took. A residence published at the same asking figure since the spring is telling you one thing: that number has not yet met a buyer who agreed with it. It is not telling you the residence is compromised, that the seller is under pressure, or that a discount is waiting.
Read alongside price history, it becomes more informative. A residence republished at a lower figure has produced a signal the first price did not. A residence withdrawn in July and back in September at the same number has produced almost none. The desk follows both, because both are observable on the public feed. Neither is a transaction record, and we do not present them as one.
The other limit is the inventory that never publishes. A material part of the upper register on this coast moves by introduction, and those residences carry no listing age at all — no appearance, no disappearance, nothing for a feed to time. Whatever the visible inventory suggests about pace, it describes only the part of the market that chose to be visible.
The figures that can be published
What can be stated, with a sample size and a date, is what the register is asking. At the snapshot of 7 August 2026, across every residence listed at €1.5 million or above that our feeds surface — deduplicated so that one villa marketed through several agencies counts once — the median asking price is €2,950,000 and the median asking rate €6,867/m², across 579 priced listings.
By zone, on that same snapshot: the Golden Mile asks a median €8,987/m², median residence €4,290,000 (n=57); Nueva Andalucía €8,652/m² and €4,289,000 (n=59); Benahavís €7,409/m² and €4,900,000 (n=81); Marbella city €7,968/m² and €2,175,000 (n=40); Marbella Este €5,599/m² and €2,925,000 (n=34); Sotogrande €5,320/m² and €3,650,000 (n=31). La Zagaleta reads €11,800/m² and €9,400,000 across five priced listings — thin enough that one unusual residence moves it, and printed here with its count attached so the thinness is visible rather than smoothed away. Sierra Blanca and Cascada de Camoján sit below our four-listing floor, so we publish no median for either.
These are asking prices. They describe what sellers are prepared to publish, at one moment, above one floor. They say nothing about what anything completed at, and no arrangement of them will.
What a seller can use instead
The absence of a days-on-market benchmark removes a crutch rather than a tool. The questions that actually govern how long a residence sits are answerable without it. Does the asking price stand against what comparable residences in the same zone are currently asking. Does the specification ask the buyer to imagine a renovation. Did the first serious viewings produce a conversation about price, or silence.
A seller who has had six weeks of viewings and no offer already holds better information than any zone median could give them, because it concerns their own residence rather than an average of other people's. The response to that information is a decision about price, and it is available at week six as readily as at month nine.
The pattern the desk observes — observation, not data — is that the residences which move without a long wait are the ones priced against the current register rather than against the figure the owner paid, or the figure the next purchase requires. That is a working view. Presenting it as a statistic would cost more trust than it bought.
Reading what is in front of you
For a buyer arriving at the upper zones for the first time, the practical implication is narrow and useful. Listing age is worth reading as a record of how long a price has stood, and worth nothing as a proxy for how quickly a zone transacts. A residence visible since March may be priced ahead of its street, or may be one of the many that never needed to move quickly. In a feed the two look identical.
For a seller, the useful signal is not a benchmark but their own sequence — viewings, the questions asked on them, offers or their absence, and what happened after the first adjustment. That sequence is specific, current and true. A zone median is none of the three.
A market report that hands you a days-on-market figure for a Marbella zone is not so much lying as omitting the sentence that matters: no record exists from which to draw it. We would rather print the asking median with its sample size beside it, and state plainly what the register cannot see.
