Is it permissible to purchase an apartment from social housing through real estate financing, and then pay off the remaining installments?

Purchasing apartments from the Social Housing Bank takes two forms: 1. Purchasing in installments directly from the Urban Communities Authority, where the bank pays the installments to the seller's account. This is permissible. 2. The bank acts as a financier, paying the price to the Authority on behalf of the buyer, and then reclaiming it with an increment. This is a usurious, prohibited loan.

If the apartment was purchased in a permissible manner, there is no objection to buying it, and for the second buyer to replace the first in dealing with the bank and paying the installments. However, if the apartment was purchased in a prohibited manner and has usurious installments, it is permissible to buy it from its owner for a spot price or in installments, without the second buyer replacing the first in dealing with the usurious bank, due to the associated prohibitions.

Therefore, if the apartment owner handles the payment of his installments himself and is the one dealing with the bank, there is no objection to buying the apartment from him.
