If I was in your situation I would ALWAYS hunt and access a property like this very very sparingly! Big bucks go where they are not harassed. Let your property be a sanctuary for these deer. Go in as little as possible to hang/check trail cams and try to do it in the rain. When it comes time to hunt it, only hunt it on days the conditions are perfect. First sits are incredibly valuable. Every time you go on the property you are leaving scent behind, everytime you go in and leave scent you're decreasing your odds of killing a big buck.
