Is it permissible to enter into an interest-bearing contract to purchase a house with the intention of selling it for profit before paying any interest-based installments, knowing that there are no Islamic alternatives available and that the sale of the house is guaranteed due to high demand?

Entering into an interest-based (riba) contract is forbidden from the outset, even if the intention is not to pay the interest, because it involves acknowledging interest and directly engaging in its contracts. It is forbidden for a Muslim to engage in corrupt contracts if he knows of their corruption, unless he imitates (follows the opinion of) someone who considers them valid.
