Any real estate agent can show you this or any other property, but beware that just because an agent shows you a property doesn't mean that he/she actually represents you. Besides that, finding homes randomly on sites like this are causing you to miss out on the ~53,000 homes for sale in the Phoenix area. Working with a Buyer's Agent will enable you to look at ALL the homes that match your needs while getting access to the knowledge and information that you need to make good decisions. Also, this property is a short sale. Short sales have about a 10% success rate of being sold with the average time taking about 4 months.
So, while any real estate agent can show you this or any property, you'll be best served by employing the assistance of one buyer's agent. When are you available to see this house?
