This house is not in the MLS for sale whatsoever. Frequently websites like Trulia, and Zillow just pull listings from websites of Realtors, and they aren't actually available. Sometimes those 3rd party websites just aren't updated.
Homes off of Singer Pl, tend to be much more expensive than the price you see listed at that link.
