If you are looking to access expired listings and comps, hire a realtor. First, interview more than one and then, be agreeable to signing a buyer brokerage agreement so the agent will be just as committed to you as you are to him or her). To find the right person for the area you are seeking to do business, ask the agent's sales record there and familiarity in the neighborhood. If you hire the right person to be your buyer's agent, then you should be able to receive information on a daily or weekly basis regarding seller circumstances and values. Any agent who is working "a farm" will be the ideal agent to help you purchase properties at the right price, and with ease in this increasingly competitive buyers' market.
