First, you should be working directly with a Realtor, rather than posting your multiple questions here.
Second, the link is to an advertisement, not a real listing. RealtyTrac uses ads that pretend to be listings in order to get you to sign up for their services. Sometimes the properties are available. More often, they're not. That's another reason for you to find an agent in your area to work with.
Hope that helps.
