The billboard promotes him as a real estate agent and appears to sit near a giant parking lot in Phoenix, AZ.
The billboard features Arie's contact information and the following slogan, "Break up with your realtor... It's okay to change your mind."
Arie captioned his Instagram post, "No roses just For Sale signs and that Dad life. Anyone need a Realtor? I'm searching for my next million dollar listing #TheRealtor."
The former pro racing driver was poking fun at his last-minute switcheroo on The Bachelor in which he dumped Becca Kufrin -- who accepted a marriage proposal from Arie during the finale -- several weeks after filming so he could reconcile with his runner-up, Lauren, who married Arie last month in Hawaii and is currently pregnant with their first child.
One follower posted some hate under Arie's photo, writing, "Hopefully if you have a daughter, you teach her how to avoid getting involved with men like you."
Lauren then clapped back at the troll and replied, "We are having a daughter and she is lucky to have him as her father. If you want to talk crap, go elsewhere."
Arie and Lauren announced they have a baby on the way in November 2018, and Lauren has been sharing the progress of her baby's development ever since.
Earlier this week, Lauren shared a picture of her baby bump on an Instagram account the couple had created for their little bundle of joy, "Baby Luyendyk."
"24 weeks old today! This week I'm the size of an ear of corn," wrote Lauren on behalf of the baby.

"My reflexes and sensory organs are developing so that means I can kick Mom with a little more coordination, I've been up super late at night and a few days ago I even managed to wake Mom up with my ninja moves."
She continued, "My little face is fully formed and I have bright white hair and even little white eyelashes because I haven't developed pigment yet (like a female Anderson Cooper). At this point my hearing is really good and I can recognize Mom and Dad's voices, they laugh a lot and talk about me too. Okay time to go, love you guys!"
Arie and Lauren's baby is due in early June 2019. The couple got engaged on The Bachelor: After the Final Rose special in March of last year.
