Would This Be an Ethical Deal?

[Davis Sessums]

So I am definitely a newbie to investing and my plan is to do fix and flips, property development, and whole sale.  I'm reaching out to distressed properties wherever they pop up in my area.  My full time job is being a firefighter, which leads to my question.  There was a house fire last night not far from me.  My department responded but I was off duty and didn't respond to it.  The house burned completely down.  I looked up the property information and it's owned by a local guy as a rental property.  Would it be ethical for me to make him an offer?  If so, how much time should I allow to pass, if any, before making an offer?  I'm sure he's up to his eyeballs in paperwork and managing this loss so I want to strike while the iron is hot but not offend him at the same time.
