Advice on removing tenants who owe large amounts when taking over

[Alexander Linville]

Hello Bigger Pockets!

In the beginning of 2020, I will be moving to Radford, VA to start operating my Grandpas rental property. All the houses need renovation but I know that is not my first priority. He has One renter who owes 1400, one who owes, 7400, and one who owes 3400. I will not be tolerating what my Grandpa did, as i want to make the property as profitable as can be(obviously). He is just very old and set in the ways that clearly never work out for him. He has threatened to evict these tenants multiple times but never followed through, as he somehow thinks they will eventually pay. How do I come in as a young adult and not piss off these tenants but get them to pay or leave without destroying the property?
