On a FB group I’m on, I’ve just seen a post which says “Exchange wanted!!! 3 bed semi detached with drive in Hertfordshire want 4 bed house in Highgate / Hampstead”.
I don’t have an encyclopaedic knowledge of Hertfordshire, Hampstead or Highgate - I am sure that there are more expensive parts of Hertfordshire and slightly less expensive parts of Highgate or Hampstead. However I should think that a 4 bed in Highgate or Hampstead would be significantly more expensive than any 3 bed in Hertfordshire, semi detached or not.
How do house swaps work? Do both houses get valued and the difference get paid?
