I thought the CNN/Reuters report said the plane veered off the runway. Possibly a blown tire. Otherwise probably a loss of power.

The direction of the skid in the grass is not in line with the direction of the runway, so he did try to steer it away from the road.
Unfortunately, for whatever reason, he beelined straight across the grass, across the road and into the waehouse across the street.
Speculation, but the green laser pointer incidents of Dec30 and Jan12 come to mind.
