Rental property with development potential - Safenwilerstrasse 5, 5742 Kölliken
Mixed rental property with land reserve | 853 m² usable space | 5 units
This versatile rental property (GB No. 1978) in Kölliken combines ongoing rental income with significant potential for value appreciation. It comprises five units with a total of 853 m² of usable space in mixed use: residential, office, sales, commercial and storage.
The rental property is offered for sale at a price of CHF 2'140'000, the adjacent land reserve of around 800 m² separately for CHF 560'000 (CHF 700/m²). As a complete package, both objects are available for CHF 2'700'000; a single acquisition is not possible.
The current target rental income is CHF 99'372 per year, which corresponds to an annualized gross return of 5.85% and a net return of 4.10%. With CHF 130'610 per year, the market potential is around 31% above the current income level; the complete exploitation is expected within around five years. After stabilization, the structural vacancy rate is only 3.2%. Three long-term commercial tenants secure a solid and stable income base.
Kölliken is located in the Aarau agglomeration, just 2.2 km from the next motorway exit, with quick access to Aarau (20 minutes), Olten (28 minutes) and Baden (38 minutes by car). The property is located in the residential and working zone WA3 and benefits from a very good road connection.
There is no contamination problem: The non-inclusion in the catalog of contaminated sites (KBS) has been officially confirmed by the authorities.
The adjacent land reserve of around 800 m² also offers investors with a long-term horizon additional development potential and represents a real added value.
