Where are property boundaries?

[Joshua Martin]

In the market to buy a duplex and owner occupy. How do I find out where the property boundaries are while doing my due diligence on the property? I'm guessing this is done separately from the inspection and appraisal.

The county or other municipality should have a plat, plot or subdivision plan. If you can find a record of an older survey that lists what the corners are marked with, that can be helpful. I usually find out what the setback is and then with a long tape measure and a metal detector can usually find property corner markers. (they're usually, but not always buried) A survey can locate corners but that's an expensive way to get the info. Asking neighbors where the property lines are can be helpful too. (helpful, not definitive, lol)

Unless I'm putting up a fence, in most cases it's just not that important...
