Hello,
Can somebody please explain in simple terms how this works? 
We have found our dream house, we weren’t planning on selling, it probably won’t happen (rush to get ours on the market) HOWEVER if we do want to put an offer in, how does it work with the mortgage?
I would assume we would need to stay with Santander so we have no exit fee. Do we phone them? Does anyone have any advice?
Thankyou v much, this is all so new
