A loan payment dispute between ASX-listed Agricultural Land Trust and prominent property fund manager iProsperity Group has reignited, more than a month after iProsperity boss Michael Gu said things were "back on track" following a "misunderstanding over fees".

The A-REIT minnow majority owned by Western Australia land mogul Allen Caratti exited a five-day trading halt on Monday to warn it may have to restate its interim accounts and report a loss, after an iProsperity subsidiary failed to pay the full amount of interest owed on loans due at the end of February.
