Sloping gardens

At last!! I've been waiting for your verdict. If it "doesn't do it for you" that all that matters. You did make a sensible decision, whatever your state of mind, because it would have been far less sensible to buy it and regret it later!!
When buying a house, I've found, that you'll never find one that is perfect. There was a Flamingo Pink bathroom in my house when we bought it - it was awful - but it worked and didn't need changing until we were in a position to do so. The kitchen was even more bizarre, modelled on a local pub's dining area with wooden roofs over all the work surfaces and louvre doors on everything - it was like something out a cowboy film. But it worked, we could cook and eat in it - and amuse our friends when they visited. The CH boiler worked - but was undersized for the number of radiators - which you didn't realise until you'd live with it through a winter............but, the house was where we wanted to live, it was big enough, had a decent sized garden and those were they things that we couldn't change.
So concentrate on your priority list - location, size, garden, structurally sound - the rest follows when you're in residence.
