Is it permissible to purchase a home through a mortgage if the intention is to own the dwelling and not to trade in it?

Purchasing a home through a bank takes two forms: the first is prohibited, which is when the bank provides the price of the home as an interest-bearing loan with usury. The second is permissible, which is when the bank buys the home and then sells it to you in installments at a higher price, provided the contract is free from any usurious conditions (such as a penalty for late payment). The bank is permitted to stipulate mortgaging the home. The need for a home does not make it permissible to engage in usury.
