Do I need real estate agent as a buyer?

[Bill Marshall]

I'm planning on buying my first property, I've already found the building I want to buy, it’s in a neighborhood that I’m familiar with. 

Question: What would a real estate agent do for me as a buyer, since I don't need help finding a place? I don’t need help with the loan. What paperwork and decisions do real estate agents or buyers agents help with?

Question 2: Should I get a real estate agent to help me close the purchase? 

Or should I hire a lawyer that’s an expert in real estate?

My banker does have experience in real estate, so I've been working with and depending on him, so far.
I assume I would be the one to look for and hire a home inspector. What else?

Thank you,

Bill
