All aspects of life moved to the new house including belongings - utilities all registered in our name at new property and internet, Sky TV + TV licence etc. Bank still at old address and HMRC too - so probably best to retrospectively inform them pdq. Have not been trying to sell the original property.
Quality of time ? Very subjective ? The old house is Victorian - the new is open plan contemporary and whilst incredibly beautiful, does not suit our family lifestyle so can't wait to move back to the Victorian. New house valued at £ 1m+ so can't afford to get it wrong and risk a potential CGT demand. Ideally would like to put new house on market in June with sale / completion likely to add another 3 months to process - would have lived at new house 9 months.
Build was completed in December and we moved in immediately. Original house was not put up for sale as we wanted to keep options open and we considered keeping it as as holiday rental ( we live on the Devon coast ).
It now also appears there is potential for another building plot on the other side of the original house and an architect is looking at this now - if this gains planning approval we will either sell the plot separately or perhaps gift the land to our eldest son who may build on it. Even if the planning permission is refused we still will be moving back regardless as that house is where we want to be.
Hope this helps.
