The flood of 2011 occurred on January the 12th, any properties sold by GBC prior to then would have still have settled. Any real estate agent will tell you that December to mid January is always slow - Christmas, holidays etc, but they will also tell you that middle of January to mid February is busy, particularly in the rental market, as people transfer into areas to begin new roles, new jobs, the school year starts etc. People often will rent before they buy. It would seem to me then that income to agency was a seasonal effect, not in those early months a "tidal" (for want of a better word and yes that was intended) effect. Given that, I would have thought that the months June, July and August when GBC was able to make interest payments to his friends, would have been the months that flood would have affected his income. Timing is out again, I think.
