Not sure on where to really start with HS (HomeSwapper.co.uk).
Initially you register for the site, input information such as current housing information, what your looking for, where etc.
Once entered there website will automatically match you into potential matches. (Matches being someone else on the site who's potentially looking for a home like yours, based on what you've entered.) You can also multi swap on the site with another third partys house.
You can swap to anywhere in England, as long as your match wants to swap and your current property passes checks+ inspection.
It's a amazing tool for people looking to either move out of area, stay in area and downsize/up size, Or even if you just fancy a change of scenery.
Don't be disheartened if people don't reply or aren't interested, everyone has their own wants/needs.
Something that needs improvement is the messaging system. Also needs an APK for mobile devices.
Genuinely really appreciate the website and what it enables you to do.
