Is it bad etiquette to knock on doors?

[Rich Nation]

When finding vacant houses, I look up the address to find out who pays the property taxes on that address and then look that name up to determine their address for where to send my letters to. My question is: Can I just go knock on their door instead of sending the letters or is that considered intrusive?

I've owned a construction company for years and have always ran my own estimates so I'm completely comfortable with talking to people at their homes. The main difference being that I have always been invited over lol.

Thanks in advance.

Personally, I would treat you the same as the uninvited bible thumpers that knock on my door. My property, my privacy, and you weren’t invited. I hate soliciting.

Ouch, I was one of those bible thumpers. It was awesome fun and such a learning experience, great way to build relationships of trust. I personally feel it it has a porch and a front door with a doorbell or knocker, it is absolutly inviting to knock.
