MTR Tenant Not Vacating Property - Next Course of Action?

[Alex Schober]

Hey all, relatively new landlord here. I've been renting my house to a family for the last three months and their lease ended at the end of March. I am reverting back to a STR strategy, with the next guests arriving this coming weekend.

The problem: the guests are demanding to stay until the end of next week, citing a clause in the lease that they have 15 days "to correct the violations of the lease", which she has interpreted as allowing her to stay 15 more days. 

Has anyone dealt with tenants that have literally overstayed their welcome? At what point should I get lawyers or even law enforcement involved? I'd like to avoid getting messy, but I may not have a choice if she continues to stay.

P.S. If any investors are in Columbus and recommend good legal counsel for landlords, I'd appreciate it!
