Can you sell your house before your mortgage is paid?
Yes, you can, of course, sell your house before your mortgage is paid off.
When a house with a mortgage is being sold the conveyancers involved with the sale from either the buyer's side or the seller's side will request a redemption statement to know how much you owe on your current mortgage. This is known as your mortgage balance and will need to be sent to the mortgage lender so they can release the first charge on your property.
Without this charge being removed the land registry will not allow a new owner to be registered on the property.
You will then be paid whatever is left over after the mortgage lenders balance has been paid off by the seller's conveyancer.
You will not be able to simply sell a property which has a mortgage on it without paying off the mortgage balance.
If you do this then this will be a fraud and you could potentially be prosecuted.
