There are several things to look for in a real estate agent - the person you trust to help you sell your house or land.
Keeping in mind that one of the ways people will be searching for their next home is by doing an area search on a map, check this out:
This is where the map is pointed to a house listed for sale in Kansas City, Missouri. Now, we do have a Kansas City Kansas as well but neither Kansas City is in China. The Listing Agent either doesn't know how to place the pin in the right place or just didn't bother to check.
So, all the buyers who are doing map searches for houses won't see this one. Is this really the agent you want to hire to help you sell your million dollar house?
