When you see this error on REA,
It means that your display price is not within the +10% or -10% of the search price.
Example:
Your search price is $500,000. 10% of that is $50,000. Now, add and subtract $50,000 from your search price.
Your display price should be between $450,000 and $550,000.
Once you update the display price, send the feed again to update the listing on REA.
