I found the best trick to neighbour relations is to be that helpful neighbour, with all the tools/equipment.

Helped the neighbour across the street wire his backyard office he built a couple years ago, helped the two immediate next door neighbours with the odd electrical wiring thing (installed a heater for one, and fixed a miswired light fixture for the other).

Kiddy-corner backyard neighbour has borrowed my lawnmower when his shit the bed (he bought an new electric one since) and borrowed my pressure washer a couple times.

I have one annoying Karen neighbour (Her name is literally Karen) who is next to kiddy-corner backyard neighbour. Apparently is a "call the city complainer", everyone in the neighborhood hates her.
(just called a noise complaint on kiddy-corner backyard neighbour about dog barking INSIDE the house). They're slightly up a hill and like to have a fire table and drink every night in the summer on their balcony, which is about 200ft as the crow flies to my house.

About 6 years ago I refinished my deck, sanding all 500sqft on my hands & knees with a belt sander. Took me 4 consecutive weekends, I'd work about 4 hours each saturday/sunday. Literally on the last weekend, saturday morning there was a passive agressive note in my mailbox, "Can you please limit your sanding to 1 hour a day". Lol no.
Anyways on Sunday I finished up, I noticed them pacing about on their balcony. I turn off the sander and shop vac for the last time, remove my earplugs and she shouts out "ARE YOU DONE YET?!?!"

I yell back "YOU BET!"

Her: "FOR HOW LONG?"

Me: "HOPEFULLY FOR 10 MORE YEARS, THANKS FOR YOUR PATIENCE!"

Later in the week I'd casually talk to my more immediate next door neighbors and ask them if they had any problems with my sanding noise, all of them were like "No, not at all!, do what you need to, Karen is crazy"
