Salam Alekum. 2 years a go i bought with my wife a house with a riba based loan. At the time we were tempted because of our housing situation. In that 2 year we renoveded the house and we feel at home but also feel guilt for our sin. Now we regret our sin en hoop Allah subhanahu wa ta'ala will forgive our sins. Should we sell the house. If yes what about the already paid interest to the bank and overvalue we get after selling the house ..? Thank you and may Allah subhanahu wa ta'ala Reward you for the help.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

You do not have to sell the house, but you have to regret it and intend not to repeat it. It is also prohibited for you to pay that usurious increase if you have a chance not to pay it. And if you can return the same amount to the bank without any increase, then you should do so. However, if you are forced to pay that usurious increase, then they bear the guilt, but you are not obliged to sell the house.

Allah knows best.
