At last it seems that progress has been made. This morning while I was making my morning tea and getting my breakfast ready a text came through from hubby telling me he was ready to get the house valued. In fact he seemed keen to put it up for sale more quickly than I do. There are a few bits of decorating and some more decluttering to be done first. I believe that these will maximise the sale price and also mean there is less to do before I move out.

This was written in May 2016 and yet took another 2 years before I actually moved from the house. There were things that needed doing within and outside of the house, but that was not the main reason for the delay. Suddenly hubby asked if I would be willing for his new partner to buy my half of the house. This meant we had to wait for her to undertake work in her house and then to sell. Right now, the wait feels worth it as everything came together at once. But it did take an awful long time!
