Here are a few.
1. How to price a home
When setting a listing price, agents consider scores of factors, from local and national market trends and neighborhood development activity to the latest buyer preferences for kitchen appliances and landscaping. Every home is unique, and an agent with a track record of success knows how to price it attractively in the market.
The Internet isn't always much help when it comes to comparison shopping, either. Many of the same factors that help an agent set an appropriate listing price aren't available in an algorithm, so online estimators aren't always accurate – and could be costly if you purchase without consulting a real, live professional.
2. Marketing offline
While online marketing can certainly be valuable, agents have networks of contacts and years of experience to round out their marketing plans.
And, for buyers, agents often can tap into their network to learn about great properties before they hit the real estate websites or even the MLS.
3. Key points in the process
If you find a home you love online, the website won't be there to guide you through a mortgage application, find a home inspector or advise you what to do if an inspection reveals issues.
4. How to negotiate
Having an experienced, professional negotiator drive your transaction can be vital to reaching a fair price for the property you're buying or selling. A website can give you an estimate of how much a property should cost, but it can't evaluate whether that's a great price or not.
