Using Real Estate Agents?

[Christine M.]

Do most investors use real estate agents when locating property to buy?

(Background: I am planning to buy some properties for lease options - and want to know if I should avoid working w/ agents. I understand that their commission is typically factored into the final sales price.)

** As an investor, do you typically use a real estate agent to help you buy property?

** If I buy a property that's currently listed w/ an agent, will the listing agent receive a commission if I buy the property on my own (i.e. if I am NOT being represented by a buyer's agent)?
