Is it appropriate to reach out?

[Travis Smith-Armwood]

So I'm stepping in to the BRRR process and I have been finding potential buy bit those homes have nobody in them. I do as a PI as well so I have the ability to pull names and numbers of owners as needed. is it appropriate to reach out to a person who initially shows no interest in selling the house (meaning no for sale signs etc).

This would mean I'm potentially calling them on a their house phone or personal cell phone that has been acquired through methods and sources that aren't associated with realestate.

Is this appropriate and if so how would that conversation start or go?
