Did I miss something, it the 200K only for finishing off the new build- I thought this was building the house?
"tarmac, electronic gates, grass, shrubs, trees, kitchen, floors, tiles - addition of sunroom, underfloor heating, cedar decking, kitchens "
In my opinion these things, which I would love, would not convince me to part with an extra 200K on a house.... I do know they are expensive to put in but it's hard to get the value back on them. When I look at property I do not look at those things, (neither for investment or home) I look at location, size of rooms etc and what I need to do to bring it to the standard I like, it's a bonus of course it the property is already high spec. On the other hand if I'd spent large sums on making the house perfect I'd find it very hard to leave just to move a short distance away.
