Wallenstam lets the remaining office space in Valvet – Mullvad VPN takes about 4 600 sq m

This is less a property-level victory lap than a signal that prime secondary office stock in Gothenburg is tightening faster than the market likely modeled. Full occupancy in a relatively small, well-located asset should support a valuation read-through for landlords with similar “best box in the right micro-market” exposure, because incremental vacancy in office is now increasingly concentrated in lower-quality or less central buildings. The second-order effect is that tenant demand is not disappearing; it is bifurcating, with growth companies still willing to pay for a compact, flexible footprint if the building is amenitized and access-centric.

The bigger implication is on reversion risk: once a property is fully let, the next upside comes from rent resets and lease term extension rather than headline occupancy. That shifts the underwriting from near-term empty-space risk to medium-term mark-to-market risk, which is usually less visible in consensus NAV estimates. If replacement supply remains constrained, the pricing power accrues to landlords with modern, central assets, while older commodity offices face a wider quality spread and more discounting pressure.

From a catalyst standpoint, this is a months-to-years story, not a days trade. The key reversal risk is macro-driven: if financing costs stay elevated and white-collar hiring softens, tenants may downshift into smaller footprints or delay expansions, reducing absorption in the next leasing cycle. But absent a recessionary shock, this kind of full-occupancy outcome tends to reinforce a winner-take-most dynamic in prime urban office, where the best assets keep leasing first and repricing higher.

Contrarian take: the market may be underestimating how much of office stabilization comes from flight-to-quality rather than true sector recovery. That means headline vacancy can look worse than the economics for top-tier owners, while lower-quality landlords suffer a longer-duration cash flow trap. For investors, the better expression is not a blanket long on office exposure, but a relative-value bet on scarce, centrally located assets versus broader commercial property baskets.
