@Justin Johnson it depends...how are you going to acquire it, and when was the last survey completed. Doing a survey may be a requirement from a lender...just depends. What does the deal look like?
Will you have an investment in the property? If so, then yes. If not, you might be willing to accept the risk. Personally, I get surveys on almost every property I purchase.
Yes, get a survey....other than obvious encroachment issues you may have easements you don’t know anything about. A recent poster actually bought the wrong property....seems like the bank foreclosed on the wrong property, one of a pair side by side.....it would have been revealed with a survey.
