It's a pretty amazing turnaround ... Jason was living on booze and coke, raking up 6 drinking-related arrests since appearing first on MTV's "Laguna Beach" and then "The Hills."
He hasn't gone far from his roots. Jason snagged this 2,250 square foot home in Laguna Niguel for $875K. As for how ... for starters he's off drugs and booze, with the help of his 2010 appearance on "Celebrity Rehab."
And paying the mortgage is doable, because he works as a big wig at a rehab facility.
Jason married model Ashley Slack back in 2013 and they are happily sunning themselves around their pool in their gated community.
That's a pretty nice reality.
