The Realty Trac fee is not that high. if your finances are that tight you may be buying too early.
Besides, you would find the service to be woefully inadequate and not at all satisfying in regards to the clarity of the property status'.
Your best bet is to contact a local real estate professional in the area you wish to purchase.
They can actaully connect you to the homes that are ACTUALLY for sale. They even have tools to dig through the distressed statuses to give you early notice opportunities. Many of these homes will require an offer be submitted through a real estate professional. And, if you don't know the process and practices of each of the banks involved, you will end up on Truila asking, "Why was my full price offer kicked to the curb?"
Of course real estate professionals do this as a business, not a hobby, and expect compensation. But you know that already, didn't you?
