Both are 1930's houses.
House A has a south facing (slightly south east actually) garden, which I prefer, but the 3rd bedroom is small with a box in it as in a box room that reduces space even more, and also a small galley kitchen.
Has small conservatory too.
House B has a north facing, slighly to the west, back garden. So I worry about light at the back of the house. But it has a bigger kitchen, the difference makes it possible to put a table in there, and also the 3rd bedroom is a bit bigger and much more usable. It's also £15K cheaper than house A. I also prefer the location of house B has although just a street away from A, B is in a kind of cul-de-sac so hardly any traffic flow. Also it backs on to a primary school so not overlooked from the back.
OR wait for a house which has a southerly aspect at the back and is also spacious inside as both houses are under budget and we can actually afford to spend a bit more.
