The question to you is why you want to buy a so called Pre-foreclosure property ? I assume because you think you getting a Deal . Every situation is different and every property is unique.my advice is you need professional help to navigate thru this myth of Foreclosure world. My advice = Stay away. It could be a major waist of time.
You can get another Realtor as my other agents mentioned in responding to your question, as a Consumer and a Realtor myself,you have to have Chemistry with your Realtor and if you loose that connection , it's over. If you don't feel that your Realtor is giving you the Time and the effort even if you are not ready,at least answer your questions and return your emails,than it's Time to move forward with someone else.just notify the previous agent that you decided to go with another realtor as a courtesy . Good Luck
