This is not a listing, it looks like one of the liens that Realty Trac pulls up against a property, possibly a tax lien, cono lienor part of a mortgage.
Unless you see an actaul address, (which this just says "west Ave", no street number, and a descriptions of the property, it is just a lien of some sort.
To have an accurate inventory of active listings you must se a search that is direct to the multple listing service. Trulia is good for generalities, but not exact. It is actaully about a month or 2 behind in reporting when property goes pending sale. And in this markety you need to know the first day a good property comes on the market, it will get mulitple offers on the first day.
My company website below is a good search option, and if you have not found a realtor to help feel free to contact me for assistance.
