Multi-Family Internet and Cable Set up

[Bassim Audi]

I am about to purchase my first 3-unit building, I do not know the current set up or layout of the cable running throughout each. My question is, how do you structure your cable so that each unit is responsible for their own cable/internet. Is this the best way to handle it? I do not want to go the dish route as a cable provider. Just starting down this path so any ideas/advice is greatly appreciated. 

Thanks!
