This CB Richard Ellis 2008 Panama condo report gives us a total of 11,428 total A B & C class active units under construction with an average absorption rate of 73%. This class of condo is ranging in average price from $1548 to $2180 per meter and are mostly targeted to the foreign market according to the report.
I question how they were able to discover the absorption rate for sales as this information is not publicly available. Where would you find the data to support sales that have yet to close. You can't really trust the developers to tell you how sales are really going. In any case it is a good read and gave me a warm fuzzy feeling for just a little while.
