i totally see the benefits of a new build but I'd love to have something that ticks all the boxes. It's a pipe dream and I'd be over the moon regardless if it ticked most like yours seems to have
Apart from the garage and being in a nicer area, we have taken advantage of the developers assisted move scheme. Basically they get our house valued, and then they market it for us, covering all the costs. It helps because the whole process is then under one roof, so each department should always know at what stage another department are at.
I was a bit dubious at first, as I thought they might under value our house, for a quick sale, so we could get into their house in less time.
I have found them to be totally transparent, and they have actually marketed our house for more than we were expecting.
