Purchasers should exercise whatever due diligence they deem necessary with respect to adjacent parcels in accordance with the terms and conditions of the purchase contract, but in any event prior to settlement on the subject property. In short, sellers are generally responsible for disclosing anything within the four corners of their property, and the buyer (and buyer’s agent) should do all the due diligence they can to learn about what is outside those four corners.And then read this story at Charlottesville Tomorrow referencing the Mosby Mountain development on 5th Street Extended/Old Lynchburg Road – Bill Edgerton (Jack Jouett) also expressed sympathy for the neighbors, but he could not support making an exception, in part because of the history of neighborhoods changing their minds on sidewalks, particularly when faced with the prospect of a new neighborhood being connected to an existing development…. Mitchell was, however, quite surprised to learn that, at least in the view of some of the Planning Commissioners and staff, his cul-de-sac was seen as accommodating a road interconnection to future development adjacent to his property…. Mitchell said that if the County ever tried to connect Hatcher Court he would both be opposed to it and try to buy the land behind him.In my view, unless you own the land around you, it is more likely than not to become, at some point, either a through road (not the cul-de-sac you’re used to) or some form of development.In this case, it sounds like the neighbors don’t want the sidewalks; but what happens in ten years when the cul-de-sacs become through roads?
