These loans are specific against projects with a cross collateral clause. projects take years to develop and sell and those lands are usually a bank land and not held for sale. that means that 12% - 13% accumulates on most loans. some are repaid as projects get built and sold. that takes a long time.
based on 13% rate and 1.25 years, 1.165 x 733 = 850. means $16M was repaid assuming no new loans. I assume lines of credit from udf are given while development takes place. that would indicate that long standing loans are declining with development loans exist now (shorter term in nature).
