House is great, garden no so much so yeah, with 3 kids that's an issue.
Depends what's actually cleared before selling but
We had a sofa like that, second hand and it was amazing so I'd be getting that checked over and cleaned and used.
The beds etc, frames can be sold or donated of not needed.
Same for lots of the other bits. If you could build in a few weeks before you had to live there, you could clear a lot without need for a skip.
The rest is surface.
No idea on the price point for that area but we'd pay that where we live
