Checklist to start out?

[Al Tresor]

Hello Everyone, i'm new here. Does anyone have a checklist of what to seek in a property in particular Single-Family / Multi-Family units ? I know this is kind of personal and depends on your goals, but still, a basic checklist of the common things to check out. Would be helpful for newbies like me to understand better and filter the properties. I'm from Italy, if there is someone in this group from Italy as well and is interested to talk about it, would be awesome! 

Thanks and have a good day!
