We are looking at buying a new house and property in Minnesota. We said that the survey and any encroachment issues need to be resolved prior to closing. The seller agreed to do the survey. We had the survey done. The surveyor found all of the original corner posts.We found that a very large shop is over the property line about 15 ft. The neighbors were at their winter home (AZ) so the son who lived there was told that the show was over the line and that we would redraw the line around the shop giving them the proper setbacks and all the seller asked was to split the redrawing fee. The son was irate and said the survey was wrong and few off the handle.The owners recently got home and did the same thing. How do we deal with this, we just want it resolved so we can close.
