Enroachment issue on two listed priperties

[Xi Chen]

Hi BP community. I would appreciate your advice on the following situation. These two propertied are next to each other. One property (with improvement) encroaches into the other property (unimproved). Both properties are listed for sale. I am initially interested in the one with improvement. However the encroachment makes me wonder what would be the best strategy. Of course I can have the seller to solve the issue as an contingency. On the other hand, I don't mind buying the lot as well if the price is right. And is that the best way to eliminate the enroachment issue? If I do go ahead and place an offer on each property, is there a way that I can list encroachment as the contingency on both offers and make the sale of one property contingent on that of the other property? Thanks.
