Ron Onyon turned to "Renovation Impossible" to help complete his home renovation, but after filming, he realized his home was incomplete and left in a hazardous state.

After investing $193,000 to be on "Property Brothers," Paul and Mindy King had high expectations but were horrified when they saw their home's renovations.
