Having a buyer's agent might be one of the smartest steps you take in the process.  Form showing you properties to negotiating contracts, pitfalls, and repairs - get represented early on to get the most out of your Realtor.

Most listed properties have listing agreements that stipulate that the seller will pay your agent to represent you!  They often also stipulate that if you are unrepresented, the listing agent will get paid the other 'side' of the commission for assisting you with the purchase.  Why not let an agent represent you?
