My mum used to be in real estate, she's a very fussy and clean person. When she would do inspections, she would have to turn a blind eye to what she would call mess (unmade beds, washing piles, few dishes in the sink etc). Not once would she say anything about it, as the tenants were simply living how most live.

If the floors were clearly dirty or walls, bathrooms etc, then yes, she would ask that they be cleaned but never re-inspect unless when the next inspection rolled around and the same problems where there again
