User blog comment:DeadJocko/What are people's opinions on finding an empty house?/@comment-28266772-20160926163331

I wouldn't recommend you enter any premises that are privately owned as a general suggestion for your own safety and to also avoid any possible legal ramifications. Needless to say some people who are inside might very well be inclined to see your presence as threatening and depending on where you are that can end very badly.

I would, especially, apply this suggestion to a house with the lights still on.

Still, if you're interested in these things I'd at least do some extensive googling on urban exploration. They will help give you more specific advice on how to tell whether a house is still occupied and hopefully it'll give you a more reliable way to know the extent to which this place is abandoned.
