Why do I need a realtor if I'm going to buy a home?

Buying a home, especially for the first time can be overwhelming.  It’s a big financial and life decision.  You want somebody in your corner.  The person(s) selling the home pay the realtor fee, typically a 6% commission, which is the standard fee.  If you don’t have a realtor, that 6% all goes to the seller’s real estate agent, and you don’t have someone representing you in the transaction.  If you obtain your own realtor, that 6% commission is typically split 50/50 so the seller’s real estate agent receives 3% and your realtor receives 3%.  Again, the seller typically pays the full 6% so why not have someone working for you and negotiating on your behalf, with your interests in mind?
