Valuation check: 75 m² duplex in Oslo, asking NOK 3,210,000 (4 bed)

[HugoYork]

Four bedrooms in 75 m² is the detail that makes this Oslo duplex difficult to value. My concern is that the room count may look stronger on paper than the usable layout feels in person.

The asking price is NOK 3,210,000, and the property is in average condition. It has good light and an appealing location, but the finishes are dated and maintenance may be due. I have three active listings for comparison and just one completed transaction, so I am reluctant to derive a broad floor-area or condition adjustment from sellers’ expectations.

I plan to start with the sale and check its date, exact street, layout and ownership arrangement. After that, should service charges and known shared work take priority over parking, outdoor space or any relevant lease term? I am using no assumed appreciation in my base case and will have the result checked through a local appraisal.

The asking price works out at NOK 42,800 per m², but I would not apply a broad percentage adjustment from the three listings. Start with the completed sale, then adjust item by item for location, layout and condition. With four bedrooms squeezed into 75 m², usable layout matters more than the bedroom count alone.

My biggest missing fact would be service charges plus any known building maintenance. Those can turn “dated but acceptable” into an expensive purchase.

How close is the completed comparable in sale date, exact area and micro-location? If it is a renovated 75 m² unit nearby, it is useful. If it is larger, on a different street or has parking and outdoor space, its price per square metre may mislead.

I would also clarify the ownership arrangement and whether “lease length” is actually relevant here. Without that, it is hard to know which adjustment deserves priority.

 

[AmberPost]

Agreed on using the sold property as the anchor, but floor area should be adjusted on a marginal basis rather than assuming every square metre has equal value. A smaller home can show a higher price per m² even when the total price is lower.

For condition, I would build low, middle and high renovation-cost scenarios rather than choose an arbitrary discount. Separate cosmetic finishes from work affecting the building or essential systems.

I’m less convinced that lease length is automatically the deciding issue; that depends on the tenure details, which have not been provided. In Oslo, the difference between two nearby streets, noise exposure, light and the unit’s position within the building could outweigh a modest finishes adjustment.

Also compare total value, not just NOK per m². Parking and private outdoor space should be treated separately if the completed sale includes either.

A practical next step is a one-page comparison grid: completed price or asking price, sale/listing date, distance, floor area, condition, service charges, parking, outdoor space, light and maintenance exposure. Give the completed sale the greatest weight and use the three listings mainly to test the current sellers’ expectations.

Then ask for details of planned building work and what the charges include. Keep appreciation at zero as planned, and run the purchase at the low valuation and the higher maintenance scenario before the local appraisal arrives.
