I guess it's different factors for different people the back garden is quite long so it will get some sun. Other factors I dont have kids, I work from home and am up early, the front of the house is long and all the sun loving flowers and shrubs are there already, also there is a park 5 minutes walk away. Whilst aspect is not ideal I viewed it on a dull afternoon and the kitchen was bright due to bright gloss cabinets, white paint and a row of velux windows in the kitchen/dining.
I am aware of plants I can can/can't use but I can landscape accordingly. To be honest the weather in the last couple of days has been crap, it's hard to tell when viewing when there is no sun can't go out in garden anyway I have a south west at the moment and only managed to get out in it yesterday, next door has a big tree blocking during the Summer so I hardly see the sun anyway at least there is nothing blocking this house just the house itself the house is awesome has all the space I want I need more room big time. It is 5 mins away from my old house near 5 bus routes and dont have to move services ie Dr., Dentist day care etc for Mam as I look after her.
