It does not maintain appropriate verb tense.
The sentence “She is hiring movers to help her with the heaviest items.” is in present tense, but the rest of the text is in past tense. For example: “Monica relocated into a new apartment last weekend.” To fix the inconsistency, the writer should change the sentence in present tense to past tense, like so: “She hired movers to help her with the heaviest items.” We know this is the correct tense (past) because it says in the first sentence that Monica moved “...last week.” (which would be in the past).
