Encroachment Discovery Before Closing

[Westen Newman]

I am supposed to be closing on a property in about two weeks (April 17th). About a week ago the title company messaged me to let me know that they couldn't find a boundary survey for the property but they did find mention of an encroachment (probably my property's fault) and they recommended getting a new survey done ($700 at most). I told my agent to tell the seller to either pay for the survey or find me the relevant documents since I feel as though this is on them (no resolution yet). This is my first property involving land (I'm used to condos) so any advice would be appreciated. Is there anything else I should be doing right now? How worried should I be about an encroachment? What have your experiences been with an encroachment? Thank you in advance for any assistance.
