Following the floods that wreaked havoc on so many Calgary homes, the damage is obvious. Streets lined with soggy drywall and waterlogged flooring are visible proof of how widespread the damage was.

But for some the damage was less apparent. On the edges of the floodwaters, the impact may have consisted nothing more than a damp carpet. However, despite appearances, residents should take care to ensure there are no potential dangers lurking out of sight.

With literally hundreds of rental units taken off the market in the wake of the recent flooding, Calgary renters could find themselves facing serious issues.

Following a pre-flood report from Canada Mortgage and Housing Corporation (CMHC) showing the city's vacancy rate fell to just 1.2 per cent in April, many prospective renters are facing a virtually nonexistent market.
