That's most likely the reason. Plus easy enough to fire up HouseSigma and see what sold within the last few months. Then check out if the new owners have showed up and off you go.I had the pleasure of meeting @Jampy00 at his new compound recently. He place isn't located on the main road. You sort of have to be going there with purpose and not just driving by. Not sure what they meant by "working in the area". Unless their idea of work is driving around trying to scam people.
When I am handing out my flyers I make a point to NOT put into any 'No junk / flyers' mailboxes, or somewhere that I can see someone is clearly a contractor / in the middle of a renovation.
They're already there, busy, and doubtful that I would drum up business there.
