MN Renters who are consistently behind on rent

[Donna Brake]

Hello, all. New to the rental property/landlord business here. We have a couple renting a house in Minnesota who is consistently behind on paying rent but they end up paying the full rent within the month, staying just out of reach of agreement termination. MN law also allows tenants the right to “pay and stay” if we begin the formal eviction process. Any advice or experience in this situation?
