Homeowner is selling house.

With notice you have to allow the house to be shown, a 24 hour notice is common, but expect some realitors to show up with less.

They will expect you to have junk put away, and the home more staged for shows, no ditry dishes, lawn keep up, junk put away.

If things need to be painted or replaced, you have to contract the owner to see about those things, Your main issue is to make the home look nice, clean.
About two years ago we were looking at houses, with renters in them, there was trash bags with trash in the front room of one, dirty dishes from several days in another. In one there was a person in bed who did not and would not get up, so we just Peeked into the bedroom could not even see it. So they want you to help with selling the home
