When to hire a professional?

Hi all,

I bought a house which was in disrepair a couple years ago and I'm still in the long process of fixing everything. While I have respect for professionals, I've been trying to DIY as much as I can to save money. I'm wondering whether finding my property boundary lines, given the map, would be something I could figure out or if it's something that really requires hiring a professional.

I have lot 120 on this map. There is already one visible marked survey boundary marker at the north middle of my property (green arrow pointing to it), and the pink lines indicate a fence line already established (but imagine the pink line being on the property line, I just didn't want to block text on the map). I have reason to believe the fence is directly on the property line because my garage lines up with the fence on the other side (and is likely a tiny bit north of the property line).

Location: Southeast Michigan

Any thoughts are appreciated. Thank you!
