Likewise for parking. Don’t divide a parking-inclusive sale by residential area and then apply that inflated unit figure to a house without equivalent parking.
I’d contact the selling agent with a short factual list rather than discuss value: area documentation, floor plan, parking arrangement, outdoor-space dimensions, occupancy, shared costs and known works. The answers can then be independently checked where appropriate.
Would you also ask why the insurance cost is a concern? That phrase may refer to an actual quote, a lender requirement, prior damage or merely an assumption. Each has a different place in the analysis.
The strongest practical step is to revisit the completed comparable in person from the outside if possible. Even without entering, the street position, frontage, outlook and access may reveal why a headline €/m² comparison is weak.
That helps, though condition still cannot be inferred reliably from the exterior. Sales particulars or other legitimately available information may show renovation level; otherwise mark it unknown rather than filling the gap.
I would not give Anyone.com’s history extra weight until its Porto coverage is checked against the completed sale already found. If that known transaction appears accurately, it is one limited test of completeness and matching.
One matched property would test identity, not complete coverage. The portal may still omit relevant sales or confuse units. It can organise leads, but the formal local appraisal and underlying records should carry the decision.
Agreed. The portal is potentially a research aid, not a substitute for verifying the transaction, area and property type. The current valuation should also remain reproducible without relying on an unexplained automated figure.
Could “townhouse” itself be causing mismatches? Listings sometimes group materially different attached homes together. Compare access, number of levels, frontage and shared elements, not just the label.
Number of levels is especially relevant to 85 m². Several small floors lose practical space to stairs and landings, so the same measured area may feel less usable than a flatter comparable.
That supports using a layout adjustment only after seeing the plan. Bedroom count is not automatically additive; five cramped rooms could narrow the audience compared with three comfortable rooms at the same area.
There’s a genuine counterpoint: a particular micro-location may attract buyers who value flexible room count despite small dimensions. I wouldn’t penalise five bedrooms automatically—just test whether the sold evidence rewards or discounts that layout.
The test could be qualitative if transactions are scarce: compare viewing appeal and competing listings with similar plans. Still, keep any conclusion modest because asking stock reveals seller expectations, not buyer acceptance.
For negotiation, present the strongest three evidence-based differences rather than a long spreadsheet. Verified area, required work and a clearly inferior feature relative to the completed sale would be more persuasive than numerous minor assumptions.
And avoid using rental value as the lead argument unless the seller is marketing to investors. An owner-occupier may price light, location and scarcity differently from an income model.
The reverse is also true: attractive light does not pay recurring costs. If the intended use is rental, model occupancy, maintenance, insurance and any service charges explicitly, then stress-test the rent rather than relying on eleven collected months.
At this stage I’d make four columns for every input: known, reported but unverified, estimated and unknown. The asking price is known; 85 m² appears reported; repair reserve is estimated; precise insurance exposure remains unknown.
That classification would also stop the single sale from looking stronger than it is. Its price may be known, while its internal condition, included parking or exact measured area could still be uncertain.
Does the completed comparable have a similar sale context? Even without assuming anything unusual, a vacant, openly marketed home may not be equivalent to an occupied or privately arranged transaction. Context belongs in the weighting.
Yes, though transaction context can be hard to establish reliably. I’d avoid discounting a sale based on rumour. Note only confirmed differences and widen the valuation interval for unresolved ones.
