A savvy real estate agent will guide you through the negotiations process and make sure everything stays on track.
Also, your agent will make suggestions such as before you move in, your home gets inspected by someone of your choosing rather than the builder's. And while REALTORs cannot offer legal advice, they can look over the contract to see if there is something in there the buyer may want to consult an attorney about.
Best of all, a buyer does not pay any commission to have an experienced agent help them sort through the process.
A new home is one of life's biggest purchases. Working with someone who represents your interests to make sure everything runs smoothly is a very smart choice.
