Do I really need a realtor? Am I missing something?

[Angelina Grace]

So Im about to go view a property I probably will buy all cash. The seller listed it on craig's list and they dont have an agent and neither do I. I do however have a prepaid real estate attorney that I can use. Does anyone know if thats all I need? Should I be contacting a title insurance company or a closing and abstract service company or can the RE attorney do all that? I will call and ask the lawyer but I'd rather do my research first so I can ask him the right questions. Am I missing something, should I have a realtor? Thanks guys, this site has proved invaluable to me.
