Dislaimer - I don't actually have a house to swap and am not entitled to one so I am purely using these facebook sites as property porn!!
But all I keep seeing is people posting, for example: lovely 4 bedroom home in West Sussex, looking for a 2-3 bed in London and getting back, for example, 'got a 4 bed in Birmingham, are you interested' (?!) I haven't yet seen a post where somebody has had success. Just loads of people offering something totally different to what the original poster asked for or asking for a multiswap which sounds horrendously complicated. I think the ability to swap is a great idea in theory but how reliable is it? I saw one lady post that she wanted a really quick swap because her house was all packed up in boxes and the lady she was going to swap with had pulled out at the last minute. What happens if a move actually happens and then one party wants to swap back? Is there any legal protection in doing this at all? Has anybody ever tried this with a positive outcome?
Just curious really. It's not something I'm doing personally. Just fallen down a facebook rabbit hole and getting addicted!
