First, I need to identify brand names. In the provided text, "Mr. Johnson" might be a person, but since it's a name, maybe it's not a brand. Wait, the user said to keep brand names. So maybe names like "Mr. Johnson" should be kept as is. Also, the brand name "Mr. Johnson" could refer to a specific brand, but in this context, it's a landlord's name, so probably not a brand. So maybe just replace each word with three variants.
"the" → that
So the first word "I'm" can be converted. Let's find three alternatives for "I'm". Maybe "I am", "I’m", "we are" (but perhaps not, since "we" changes context). Alternatively, "I am", "I’m", "we are". But maybe better to stick with similar pronouns. Maybe "I am", "he is", "she is". But that may not make sense. Alternatively, perhaps in the context, the same pronoun can be used but with synonyms for the verb. thmyl rnt bghnyt syrytl
