This property just came on the market yesterday at $349,900. It shows as a 4-plex, but previous listings show it as a triplex. Without seeing the property from the inside there is no way of telling how much work it needs, but you can offer what you think is a reasonable price for the property.
Now keep in mind that most properties have multiple offers and they are selling at a higher price than the list price, but this might be an exception.
I work this area and know it well, if you have any questions please feel free to e-mail me at firstname.lastname@example.org or call me at 323.359.7992.
