If you haven't officially begun your search, consider the benefits of using a Realtor to assist you. By utilizing the expertise a Realtor can provide, it will cut down your search time will very likely save you money in the long run, especially when dealing with those selling their homes For Sale By Owner. In general, FSBO's are overpriced and when dealing with the seller directly, you may not get all the answers you need. By utilizing a Realtor, you will be guided through the process and you won't need to worry about having to find a lawyer or title company or anything else, because you get all the legal stuff included by simply having a loyal relationship with your Realtor.
I'm a Sales Partner on the EZ Sales Team and we don't charge our buyers at all to utilize our services on the "buy side" as we refer to it in the industry. You deserve to be represented appropriately by a knowledgeable agent who will look out for your interests and protect you from overpaying for your single largest investment.
If you're interested in working with an agent, feel free to contact me and I'd be happy to meet you for coffee to discuss how I might be able to help.
If you have seen the house, then a Realtor does not "technically" have claim to any commission because they were not the "procuring cause" for your home purchase. I do have a deal in progress at the moment where I represented the buyer and she purchased a For Sale by Owner home. In this case, the seller is unrepresented and the buyer is represented by my brokerage and me. In the past, I have handled the paperwork for a fee.

Have you already been shown the house by the seller? If so, then there isn't much a real estate agent can do for you. You definitely should have an attorney help you with the transaction.
If you were shown the house by a realtor and the seller agreed to pay the realtor a commission, you would then have the benefit of possibly using that agent's company' attorney.
However, if you haven't seen the inside of a house yet, and this is a fact-finding question before the fact, then there's still time! I'd be happy to help, if that's the case!
