So we went to view a house we loved. A rural farmhouse with small parcel of land however on viewing realised it has another parcel to the side of it with caravan on. Asked the agent who it belonged to and they were vague. So before we made an offer I knocked the farm next door. To mainly discuss the access track that runs over thier land and they told us that small parcel of land next to the house with caravan was actually owned by the house In question. The grandchildren of lady who had lived thier (now deceased) frequently partied there. We then went and had a nose and there were beer bottles etc everywhere. I then referred this back to agent who then came back with that the family wanted to keep that part of the land to continue to stay in the caravan a few times a year and share the houses water supply (a well). We have gone back and said we would happily buy the house for the guide price and pay additional 15k for land which is approx 1/3 acre but won't consider buying it without it. My primary concern is that 1. Grandchildren could still party there and 2. What's stopping them renting caravan out etc? It is our responsibility to maintain track etc which they would also need to use to access caravan. Also where would they go to toilet etc. It is currently linked to house electrics which obviously it would be disconnected. I worry it could cause alot of issues. They are still yet to respond to our offer (made 8 days ago) they have had no other offers. Why are they taking so long to respond its driving me insane. Should I ring and put a deadline on the offer? Are we being unreasonable with concerns?
