The long and short of it:
My DM's house is in a state of disrepair. After many years of inertia she finally accepts that she needs to sell.
A few days ago (after mentioning possibility of selling to NDN), a letter appeared from another neighbour, asking that if she does want to sell, would she consider them. They are currently renting and missed out on another house sold in the same street a few months ago.
From what DM has told me (I haven't seen the letter yet), they are talking up the fact that it could be done privately. They know that the house needs work and have the time to do it whilst staying in their current rental. They are desperate to stay on the street for family reasons and, to be honest, they tick a box that, quite rightly, couldn't be guaranteed on the open market, which is that my DM wants the house to be sold to a family that will love and cherish it. I don't doubt for one moment that this family would be the perfect owners.
We are clueless though! What are the legalities of selling privately? I've only just found out about it, so will do as much research as I can, but if there is anyone out there with any experience or advice it would be very much appreciated.
