Buying a home is one of the most expensive purchases you make in your lifetime. The average homeowner usually spends around 1/3 of their monthly income on their home. A good Buyer's Agent is invaluable to a Buyer and may make the difference between a nightmare and a wonderful transaction.
Listing Agents almost always enter into a legally binding contract with the Seller that require the agent always act in the best interest of the Seller, your Buyer's Agent is there to negotiate for your best interests. You, the Buyer, don't pay any fees (the listing agent does.)
The average person buys 3-5 homes in a lifetime, a good Buyer's Agent assists in 3-5 transactions per month. Experience counts, what may seem complicated and intimidating to you is fairly common and familiar to your Buyer's Agent.
Make sure you use a Buyer's Agent in any real estate transaction and make sure your Buyer's Agent is a Realtor.
