Buying a home typically requires a variety of forms, reports, disclosures, and other legal and financial documents. A knowledgeable real estate agent will know what's required in your market, helping you avoid delays and costly mistakes. Also, there’s a lot of jargon involved in a real estate transaction; you want to work with a professional who can speak the language.

A great real estate agent will guide you through the home search with an unbiased eye, helping you meet your buying objectives while staying within your budget. Agents are also a great source when you have questions about local amenities, utilities, zoning rules, contractors, and more.

You want access to the full range of opportunities. Using a cooperative system called the multiple listing service, your agent can help you evaluate all active listings that meet your criteria, alert you to listings soon to come on the market, and provide data on recent sales. Your agent can also save you time by helping you winnow away properties that are still appearing on public sites but are no longer on the market.

There are many factors up for discussion in any real estate transaction—from price to repairs to possession date. A real estate professional who’s representing you will look at the transaction from your perspective, helping you negotiate a purchase agreement that meets your needs and allows you to do due diligence before you’re bound to the purchase.

Most people buy only a few homes in a lifetime, usually with quite a few years between purchases. Even if you’ve bought a home before, laws and regulations change. Real estate practitioners may handle hundreds or thousands of transactions over the course of their career.

A home is so much more than four walls and a roof. And for most buyers, a home is the biggest purchase they’ll ever make. Having a concerned, but objective, third party helps you stay focused on the issues most important to you when emotions threaten to sink an otherwise sound transaction.

When you're interviewing agents, ask if they're a REALTOR®, a member of the National Association of REALTORS®. Every member must adhere to the REALTOR® Code of Ethics, which is based on professionalism, serving the interests of clients, and protecting the public.
