Sorry, I wouldn't. It's obviously a family home, with 4 bedrooms, but it's too disproportionately top heavy for my liking. There's not enough space on the ground floor, particularly the living room. My house is smaller than yours (just a three bed modern terraced) but my living room is larger. So personally, the size of the living room would be the deal breaker for me, as I don't think it would fit my family of teens + boyfriends all in at once.
Sorry, that's not very helpful, because you can't do much about that... but it might just be that it's the kind of house that won't attract everyone and you just need to wait for the right type of family to buy it, iyswim.
