Explanation: Since in this passage there are still no references to the character of Miss Lottie, it is not yet possible to infer that she was an outcast who did not take care of her home, as she truly was. In addition, it cannot be inferred that she lived alone (which she didn't) or that she wished she could afford a better house. The description of the house, however, does reveal that hers was one of the most rundown homes in an already extremely poor neighborhood, since it was not properly maintained.
