Landlord tenant laws

[Matt Stoltzfus]

I'm in the process of selling my rental property. Realtor showed it to a buyer and we have an accepted offer signed. Now the tenant is not working with my realtor to get inspections scheduled and done. Tenant claims I as the landlord have to give them the 24 hr notice and not the realtor.

Can anyone tell me what the law actually is on giving tenant notice of entry and do they have to approve the time and date or can the landlord give a notice and show up no matter what? Property is in Wisconsin and tenant is handicapped as well with a caretaker.
