My husband and I are interested in buying a property that is not currently on the market. It has a lot of sentimental value (family reasons) and we'd really like to approach the current occupiers (who we know a little but not well) with an offer. They have not lived in the property for a long time (less than six months) and do not have any emotional attachment to that particular house as we do. Does anyone have any experience of doing anything like this? Any advice that you'd give in our situation?
