Condition Level and Price per m2: How Condition Drives Value

Two homes in the same stairwell, with the same layout and the same number of square metres, can end up with prices per square metre that lie far apart. The location is identical, the area is recorded the same way in BBR (the Buildings & Dwellings Register) — and yet the market draws a sharp line between them. The most important explanation is rarely anything that shows up in the registers: it is the condition of the building. Condition is the factor that moves price per m2 the most when everything else is held constant, and at the same time the one that is hardest to read off the paperwork.

For a valuer, agent or investor, it is therefore not enough to know area, location and year of construction. Condition level is a value factor in its own right that you cannot calculate your way around — and if it is not handled explicitly, the uncertainty bleeds into the entire valuation. This article looks at how condition is assessed in practice, which levels separate one home from another, and why condition should be treated as a variable in its own right rather than buried in an overall gut feeling.

Why condition is a value factor in its own right

When a property is priced, it is always done relative to a market of comparable sales. Two homes with the same area and address share most of the basis — location, local-plan conditions, amenity value, infrastructure. What is left to explain a price difference is typically the state of the physical fabric: kitchen, bathroom, floors, windows, services, the building envelope and general maintenance.

The point is that condition is not a derived quantity. It only partly correlates with the year of construction — a well-kept property from the 1930s with ongoing renovation can be in better shape than a building from the 2000s that has never been maintained. BBR tells you when a renovation was last recorded, but not whether the bathroom is genuinely worn out, or whether the roof is nearing replacement. Condition therefore has to be assessed on its own, beyond the register-based baseline data. If you want the full picture of how condition interacts with the other variables, we have described how a property is valued on the existing market in a broader walkthrough.

Rule of thumb: When two otherwise comparable homes differ markedly in price, start by examining the condition before you look for explanations in location or area.

How a building’s condition is assessed in practice

Condition is a holistic judgement, but it can be broken down into concrete elements that each contribute. In practice you look at:

• Kitchen and bathroom — the two most expensive rooms to renovate and the ones the market reacts to most strongly. A new, fully finished bathroom lifts the price more than almost any other single intervention.
• Building envelope — roof, façade, windows and insulation. This is where the large, deferred costs sit, and a visibly worn envelope drags the price down because the buyer factors the expense in.
• Services — electrical, plumbing, heat source and drainage. Often invisible, but expensive to bring up to standard, and the energy label gives an indication of the level.
• Surfaces and finish — floors, walls, doors. What determines the first impression and therefore the perceived condition.
• State of maintenance — whether the property has been looked after on an ongoing basis, or whether a backlog has built up.

Renovation condition versus year of construction

Renovation condition is the factor that most often creates distance between two otherwise identical homes. A flat that has been fully renovated within the last few years is valued differently from one that stands original from construction — even though the square metres are the same. Conversely, a newer home that has been driven hard and never maintained can drop a level. That is why it matters to separate when the building was constructed from what condition it is actually in now. The energy-label register and BBR’s information on the most recent conversion or extension are useful anchor points, but they do not replace a concrete assessment of the condition.

The typical condition levels

To make condition operational, homes are usually divided into a number of levels on a scale from run-down to exclusive. The number of steps varies from method to method — some work with a few broad categories, others with a finer division into seven levels to capture the nuances. The logic is the same: each level corresponds to an addition or deduction on the price per square metre relative to the area’s typical mid-range condition.

In broad terms, the scale covers the following:

1. Run-down / renovation project — comprehensive refurbishment required. Priced with a deduction equal to the expected renovation cost plus a margin for risk and inconvenience.
2. Low / original — habitable but dated. Kitchen and bathroom of an older vintage.
3. Mid-range — ordinary, maintained condition with no comprehensive renewal. The reference point the other levels are measured against.
4. Good / partly modernised — newer kitchen or bathroom, updated surfaces.
5. High / fully renovated — a modern, fully finished level throughout the home.
6. Exclusive — consistently high quality in materials and finish, often with added architectural value.

The decisive thing is that the level is chosen relative to the area. A “high” level in a provincial area and a “high” level in a sought-after city neighbourhood produce different kroner per m2, because the starting point — the area’s average price — is different. We cover how the area-based basis is formed in price per square metre for an area: how it is calculated and read.

Why two similar homes end up with very different prices

Place two identical flats side by side. One is fully renovated with a new kitchen, new bathroom and new surfaces; the other stands original and dated. The market will price them differently, and the difference is not only the bare renovation cost. The buyer is also paying to avoid the hassle, to be able to move in straight away, and for the risk that a refurbishment can always end up more expensive than budgeted. The condition premium is therefore often larger than the bare builder’s bill.

It also means that condition is the direction in which a property can be moved in value terms. For the investor, it is precisely the distance between the current condition level and the achievable level after renovation — set against the cost — that decides whether a deal makes sense. For the valuer and the agent, it is about placing the property correctly on the scale, so that the comparable sales pulled in are genuinely comparable on condition too, and not only on area and location.

Putting a number on condition without guessing

The challenge with condition is that it is qualitative by nature, but has to be translated into an addition or deduction in kroner. Done on instinct, the assessment becomes hard to verify and depends on the individual valuer’s calibration. The more robust approach is to let the market itself reveal what a step in condition costs: by looking at actual sales in the same area, where homes at different condition levels have been sold, you can derive what the market actually pays for a step up or down — rather than setting the figure by discretion.

That is exactly the exercise Valuation (Boligvurdering) in Arcili automates. Condition level enters as one of the factors the model assesses against — together with location, area, planning conditions and the other variables — and is calibrated against actual sales in the relevant area, so the condition premium reflects the current market rather than a free estimate. The result is delivered with a confidence level, so you can see how solid the basis is. How good a model of this kind is compared with a manual assessment, we have looked at honestly in how accurate an automated property valuation really is — the automation does not replace professional judgement, but it makes the condition assessment faster, more consistent and easier to verify.
