I always go introduce myself after I move in, but only if they have property abutting mine. It helps to avoid conflict if you have a phone number or something. “Hey, my moving truck is arriving this Thursday with my stuff and will block access to your driveway in the afternoon. With apologies. If this will cause you problems, please let me know and we can work something out.” Or whatever.
There’s a phrase that goes “good fences make good neighbours” and I hate the phrase.
