Is it permissible to purchase a house if part of the price will be paid to the bank to cover a usurious loan owed by the seller?

There is no objection to purchasing a house and directly settling the seller's debt to the bank, provided that there is no usurious transaction between the buyer and the bank. However, if it necessitates opening an interest-bearing account, then it is impermissible; instead, the buyer should give the full amount to the seller so that he may settle his debt himself. It is important to note that the apartment may be mortgaged to the bank, and in this case, it is not permissible to sell it without the bank's permission.
