I just finished reading Ines's featured blog Working Without a Realtor. There were 71 comments that I waded thru, and if you haven't taken the time to do the same, you should. Another excellent blog is Janie Coffey's The Benefits of Working With a Realtor That Specializes in Your Area. Ki Gray has written Why Use a Realtor?.

Now please don't get mad.
I'm a consumer with a question! This is not an attack on my agent friends here or any kind of personal charge, it's just a consumer question.

What I'm learning so far at Active Rain is that a buyer's agent "represents" you, the buyer. They will:
- negotiate the price for you
- understand the local market
- know the inventory and comparables on the market
- be able to point out what's good and bad about the property
- ease you through your buyer's remorse and emotional swings
- be able to give you, the buyer, "the inside scoop"
This is my question: IF the sellers have disclosed honestly what the condition of the house is, IF the buyers hire a home inspector, IF a buyer spent the time researching homes that have sold in the area and studied the internet for what's on the market and for how long, what are they missing?
It seems to me "the inside scoop" may be private information that the seller doesn't want the world to know, e.g., divorce, death, personal circumstances that are no one's business. Or isn't privacy respected anymore?

The Internet is not capable of evaluating a buyer's personal needs and their motivation in the buying process. It cannot counsel a buyer specifically on those individual needs that are unique to their situation. It cannot guarantee that a buyer will understand or fully comprehend what they see online. It cannot answer individual questions they may have about specific issues or concerns. These, among many other things, are "missing" from the process of getting all one's information off the Internet.
Your question is predicated on a lot of "IF" statements. Let's take this a step further. Is the seller a home inspector? Are they expected to know everything mechanical or structural about their home? Can a home inspector replace all the advice and counsel provided by a real estate licensee?
You ask "IF a buyer spent the time researching homes that have sold in the area and studied the internet for what's on the market and for how long, what are they missing"?
I don't know what the author meant by an "inside scoop". But I'd say your hypothetical buyer question can be readily answered. The human element in real estate counseling and the buying process won't easily be replaced by the Web or by any other robotic process. If it were that simple to eliminate the middleman and do it all ourselves, we'd have no more stock brokers, insurance salespeople, car salespeople, investment advisors, tax preparers, CPAs or attorneys.
Ask the buyer this.. How much time do you have to devote to doing this all yourself? What is your time worth? And if you have that much time on your hands, are you employed and do you have the financial means to be looking at property in the first place?
