Oahu real estate can be confusing unless you are familiar with the various Oahu real estate areas. There are general areas of Oahu, such as East Oahu, West Oahu, Windward Oahu, Leeward Oahu, Central Oahu, and the North Shore. Oahu real estate is also broken into various MLS Regions by the Honolulu Board of REALTORS, as shown below. 

The Oahu MLS regions, which you or your REALTOR will use to search for properties of Oahu, denoted on the Oahu real estate map above.

When looking for Oahu real estate, it is also helpful to be familiar with the towns and cities on Oahu, as well as the Oahu regions and neighborhoods, as the MLS is searchable by these criteria also.  To help understand the distinction, we've broken this information down a little further, by Oahu cities, and Oahu areas, in the Oahu real estate areas chart below:

Within each of Oahu MLS Regions (far right blocks), there are a dozen or more Oahu neighborhoods.
