Oscar Properties, one of several highly indebted Swedish real estate groups buckling under soaring borrowing costs and slower demand, said in a statement Carl Janglin would stay on as CEO until a successor had been appointed.

Janglin and CFO Magnus Thimgren both took on their jobs last year.

"We thank them for their efforts during this difficult period. The work on liquidating the company's remaining debt obligations and securing the company's assets now continues," the company said.

The problems at the relatively small player have been exacerbated in recent quarters by some creditors demanding immediate repayment of loans, and two applications for it to be declared bankrupt, one of which was later withdrawn.

The unfolding property market crisis in the Nordic country is threatening to engulf the economy.
