A good agent doesn't really begin to earn a commission until the home is found. That's when you need an agent the most. If you excluded your agent from negotiating the contract on your behalf, protecting your interests within the contract, meeting contractual deadlines, scheduling inspections, working with your lender, coordinating with the title company, etc... then you're proceeding without a safety net.
If you're not under a signed agreement, you can represent yourself. Just know that a whole host of things can go wrong and if you're not prepared to deal with them or are unaware of their existence, it could cost much more than the agent's commission in the long run; Which will come out of your pocket instead of the seller's.
If you are under a signed agreement, breathe a sigh of relief and get ready for a smoother transaction. If you have any concerns during this time, contact the broker and express your concerns.
