Kernrechtsfrage
Whether the gains from selling the condominium units were taxable as self-employed income or exempt private capital gains.
Extrahierter Entscheid
The overall activity amounted to self-employed real estate trading, not mere private asset management; the gains were taxable.
Extrahierte Begründung
The court relied on the planned subdivision, real partition, construction, repeated sales, financing structure, professional background and the close link to the couple's construction business. The totality of circumstances showed an activity aimed at profit.
