I have checked the asking price, stated area and basic condition. What remains unclear is whether the evidence is comparable enough to support meaningful adjustments.

This is a 5-bed Barcelona condo of about 225 m², offered at €892,400. It has good light and a strong location, but dated finishes. I have three current listings and one recorded sale, with possible differences in outdoor space, occupancy or lease terms as well as condition. How would you use that limited evidence without giving the price-per-square-metre calculation more authority than it deserves? The exact area definition is one item I still need to confirm.
 
I would anchor on the completed sale and use the three listings only to show the seller’s competition. Before adjusting anything, how close is that sale in micro-location, sale date, floor, light and building quality? If it is not genuinely similar, one transaction can create false precision. The biggest missing fact for me is whether the 225 m² is measured on the same basis as the comparables.
 
Yes, the area definition could move the result substantially. Is 225 m² the interior usable area, a constructed figure, or a figure that includes some share of common space? Apply the same basis across all four comparables before calculating price per square metre. Otherwise the apparent condition discount may really be a measurement mismatch.
 
The asking price works out at roughly €3,966 per m², but I would not apply a simple citywide rate to such a large unit. Larger condos can have a different per-m² pattern from smaller ones, and five bedrooms may appeal to a narrower set of buyers. A floor-area adjustment should come from similarly sized properties, not a fixed amount multiplied by every extra metre.
 
“Average condition” is too broad for a percentage adjustment. Separate dated but usable finishes from items that may require substantial work. Then obtain realistic quotes and allow for disruption rather than guessing a blanket discount. I’d also want the current service charges and any known building works; an attractive interior price can be offset by costs outside the unit.
 
I’d put condition below micro-location in the hierarchy. Two Barcelona properties can look close on a map and still differ materially in outlook, noise, access and immediate surroundings. The claimed light also needs unpacking: orientation, floor and whether it is likely to be obstructed matter more than bright listing photographs. Does it have outdoor space or parking, and do the comparables match those features?
 
I partly disagree on putting condition so far down the list. At 225 m², even ordinary updating across the whole condo can be meaningful, so buyers may price the inconvenience as well as the work. Still, I would not deduct renovation cost twice: once through a condition adjustment and again through a lower assumed €/m². Build one explicit adjustment and test it under low and high cost scenarios.
 
The occupancy point may be the fact that changes the valuation most. Is it vacant, owner-occupied or sold with a tenant? If tenanted, the remaining lease length, rent and relevant terms need to be understood locally, especially given your concern about rental regulation. That can affect both income assumptions and the pool of buyers, so it should not be buried inside a general “cost” allowance.
 
The evidence needs sorting before it needs adjusting. My concern is that differences in measurement or occupancy could be mistaken for differences in condition.

I would put the completed transaction and the three listings into a simple grid covering date, exact location, area basis, floor, light, condition, outdoor space, parking, service charges and whether the property is vacant or subject to a lease. Use the sale as the main reference if it is genuinely close. The listings can show the current competition, but not what buyers ultimately paid.
 
Also confirm whether parking is included in the €892,400 or available separately. I would strip parking out of every comparison before deriving the condo’s €/m², then add an appropriate parking component back only after finding genuinely comparable evidence. The same principle applies to terraces or other outdoor space; treating them as ordinary internal floor area will distort the calculation.
 
Parking and outdoor space are the details that make me hesitate about any tight valuation range. Either can distort the apparent €/m² comparison if it is bundled into the €892,400 or treated like internal living area.

I would first put all properties on the same 225 m² measurement basis, then separate parking and terraces. After that, check occupancy or remaining lease terms, service charges and planned building work. Condition can be tested as a range rather than a single deduction. If the price works only when every uncertain item is viewed favourably, that gives you a clear negotiating position while you wait for the local appraisal.
