Someone found my exact address. How?

I was chatting with a guy. We didn't have any friends on Facebook, we just accepted messages on Messenger. He didn't know my first name, last name, city, and area of residence. After a while, he told me to wait a few minutes so he could find out where I lived. He asked if we owned it or rented it. I answered that we (our family) owned it.
Then he sent me a screenshot of our house from Google Maps.
Now the question is: how?
Apparently, this is some kind of secret that he won't tell me, and I'm not sleeping because I can't figure it out.
How can I find out?
