In the May 2026 snapshot, Spain’s largest asking-versus-sold apartment price gaps were concentrated in a mix of coastal lifestyle markets and a handful of provincial capitals. For buyers, agents, and researchers, these are the places where price discovery looks least aligned: Bailén-Miraflores topped the list with a 183.6% gap, while Sitges and Calpe / Calp also posted triple-digit readings.

The biggest gaps sit well above 100%, signalling markets where listings and closed-price benchmarks are far apart

In the May 2026 snapshot, the ranking was led by places where the spread between median asking prices and MIVAU sold-price averages was exceptionally wide. Bailén-Miraflores posted the largest gap at 183.6%, with a median asking price of €246,581 against a MIVAU average sold price of €86,957. Sitges followed at 141.3%, with €646,972 on the asking side and €268,128 on the sold side.

Calpe / Calp came next at 126.8%, based on €444,335 versus €195,888. Benitachell / El Poble Nou de Benitatxell reached 123.1%, with €437,010 against the same €195,888 sold benchmark shown in the dataset. León rounded out the top five at 115.2%, with €222,167 in asking prices and €103,252 in sold prices.

Wide gaps of this kind often show up where listing ambitions outrun the prices captured in completed transactions, especially in markets with heterogeneous stock or slower price agreement between buyers and sellers.

Coastal and second-home markets feature heavily near the top of the ranking

In the May 2026 snapshot, several of the largest gaps were found in Mediterranean destinations with strong second-home or international-buyer profiles. Sitges, Calpe / Calp, Benitachell / El Poble Nou de Benitatxell, Almuñécar, Altea, and Jávea / Xàbia all appeared in the top 10.

Among them, Sitges had the highest asking-price level at €646,972 and also one of the largest transaction counts in the dataset at 20,694. Calpe / Calp showed €444,335 against €195,888, while Altea registered €397,948 against €195,888. Jávea / Xàbia stood at €383,300 versus €195,888, and Almuñécar reached €312,499 versus €146,269.

This pattern is notable because lifestyle markets often carry a broader spread of product types, renovation standards, and seller expectations, which can leave advertised prices looking more ambitious than benchmarked closed transactions.

Provincial capitals also appear, showing that the gap is not only a resort-market story

In the May 2026 snapshot, the list was not limited to coastal municipalities. León, Ourense, and Ciudad Real all ranked among the widest apartment asking-versus-sold gaps, despite much lower price levels than the coastal names above them.

León recorded a 115.2% gap, with median asking prices at €222,167 and MIVAU sold prices at €103,252. Ourense stood at 106.6%, with €212,401 against €102,787. Ciudad Real was just below the 100% mark at 99.0%, with €168,456 on the asking side and €84,638 on the sold side.

For negotiators, that matters: a large gap can exist in mid-priced cities as well as in premium destinations, so the mismatch is not simply a function of headline price levels.

Transaction counts help separate broad benchmarks from thinner local evidence

In the May 2026 snapshot, MIVAU transaction counts varied sharply across the ranked cities. Sitges had 20,694 recorded transactions in the underlying sold-price benchmark, while Calpe / Calp, Benitachell / El Poble Nou de Benitatxell, Altea, and Jávea / Xàbia each showed 13,958. At the lower end, Ourense had 971, León had 1,918, and Ciudad Real had 2,255.

Population sizes also ranged widely. San Sebastián - Donostia was the largest city in the table at 189,866 residents, followed by León at 123,446 and Ourense at 105,769. At the other extreme, Benitachell / El Poble Nou de Benitatxell had 4,911 residents, while Cunit had 16,385 and Bailén-Miraflores had 17,119.

That mix is useful for interpretation because large pricing gaps can appear in both bigger urban markets and smaller municipalities, but thinner local populations and narrower stock pools often go hand in hand with more uneven listing behaviour.

Even the lower-ranked entries still show substantial disagreement between listing and sold benchmarks

In the May 2026 snapshot, the bottom of this top-12 ranking still reflected sizeable divergence. Cunit and San Sebastián - Donostia both posted an 85.9% gap, which would still count as a major mismatch between asking and sold benchmarks in most city comparisons.

San Sebastián - Donostia paired that 85.9% gap with the second-highest asking price in the table at €593,260 and a sold benchmark of €319,101. Cunit, by contrast, showed €305,175 against €164,158. The contrast underlines that similar percentage gaps can appear at very different absolute price points.

For buyers preparing offers or agents calibrating comparables, the practical takeaway is straightforward: in these cities, listed apartment prices appear materially detached from the sold-price benchmarks captured in the same snapshot, so negotiation ranges are likely to matter more than headline ask levels alone.
