Is installment payment with bank interest for the company to buy a house considered permissible or forbidden?

The question is unclear, but if the company sells the apartment at a specific price and its profit is included within the total price (the 40% paid in installments), then there is no harm in that. However, if the interest is added to the remaining installments as a result of debt or installment payments and is not part of the agreed-upon price, then this is explicit usury (riba) and is not permissible.
