First-time home buyers are generally engaged in some other business apart from real estate, so they tend to know very little about real estate. Most experienced real estate agents are in the business full-time, so they acquire knowledge every single day. The business of buying a home is complicated, filled with paperwork; it requires expert negotiations and there are often small problems which, if left undetected, can easily blow up into proportions so huge that your entire transaction could be placed into jeopardy.
My advice for first-time home buyers is to hire a buyer's agent to work for you. In almost every instance, the seller pays the fee for your buyer's agent, so it costs you nothing extra.
