If you want to know exactly where the property line is, just watch the neighbor cut the grass. 
Well, I'm sure we've all been asked the question, and I'd bet we all responded ethically:
Question for Realtor from Potential Buyer: "Where are the property lines?"
Realtor: "For an exact answer, you would need to have a surveyor make that determination. But I think on this side it's near the street, and on that side it's near that tree....."
Fortunately, I've not run into many property line disputes, but the few I've been involved with concerned the placement of fences. "Open and notorious..." Dangerous words!
So, any great stories out there about such issues? I'm sure we'd love to hear them!
Thank you!
