The home is listed in "Poor" condition, which is the lowest category. I would assume it is unlivable without a lot of rehab. It's being sold "as-is".
The listing also says that it must be purchased as a package with 289 Sherman Street which is on the market for 39000. This could be a major reason why it hasn't sold. (Or why 289 Sherman hasn't sold!)
I would recommend working with a buyer's agent that you trust. On listed properties, a buyer's agent works at no cost to you. This means you'll get an expert's advice and opinions for free! Your questions are pretty specific, so if you're serious about buying, that would be my suggestion.
Best of luck to you!
