You can definitely submit an offer without a buyer's agent (we just did this successfully with no issues) - the listing agent should have you sign paperwork that they are not representing you, but they are just facilitating the transaction.
Buyer Agency – The agent works exclusively for the buyer, advocating for their best interests in negotiations, market analysis and the overall purchasing process. Ohio law requires the agent to present a buyer representation agreement before showing properties or performing services.
Under the new law, buyer agents are required to have a written agency agreement in place, including details about compensation, before they can conduct most real estate activities and transactions on behalf of their clients.
If you don't want to sign a buyer agency agreement, you always have the option to represent yourself in a real estate transaction. The Ohio Department of Commerce Division of Real Estate and Professional Licensing doesn't recommend that, though, because of the risk of costly mistakes.
REALTORS® are negotiation experts. If you buy a home without an agent, you'll have to negotiate and decide how much to offer on your own. This may cause you to unknowingly overpay for your home – or lose out on one you want.
