Either the 1st or the 3rd one. The 2nd one looks dated and cramped.
What puts me off the first one a bit is that it seems close to the neighbours, but garden is nice, seems spacious.
House 3 is a bit more distant from the neighbours, nice garden. Not as nice inside as House 1 but easily sortable. Seems like maybe more downstairs floor space but not sure if some/one of the upstairs rooms might be a bit small so I'd need to visit.
