Inside Roloff Family Farm’s incredible 16-acre property with historic homes & biking trails as it’s up for sale for $4M

, Matt explained: "Today 16 acres of the farms 109 acres . including our original family home and bright red barn.

"It’s a tiny bit scary but mostly exciting. It's time to move toward the next season of life."

Sixteen out of 109 acres may not sound like much, but the area for sale includes some unique properties not likely to be found anywhere else.

As the real estate company in charge of the sale explains: "The 100-year-old farm with stunning views of rolling hills, green landscapes and coastal mountain ranges, has an incredibly rich history.

"Owned by just three families over the past century, the property sits on 16-acres, fortified with fertile soil ideal for growing pinot noir
grapes, blueberries, pumpkins and all manner of fruit trees such as apple, plumb, cherry and peach."

As for the main house itself: "The 5,373 square foot farmhouse mountain home consists of five bedrooms, five full baths and a powder room on the main level."

The main floor features matching his and her offices, a bonus room and an unfinished basement.

There is also a six car garage and outdoor pool for entertaining.

"The extremely rare property also includes several independent structures that add to its uniqueness and charm," the realtor statement continues, "including a 3594 square foot classic red and white barn."

The barn also features another studio apartment with a private entrance.

But it is the rest of the land that really stands out.

"Bursting with character, the property grounds can best be described as an elaborate fantasyland for children," the release reads. "Some of the whimsical installations include a full-scale pirate's ship, a western town complete with a jail, bank, sheriff's office, general store, hotel and blacksmith's shop modeled after Knotts Berry Farm and a German-inspired medieval castle."

Matt, 60, explained the history his family has with the home.

“I have dedicated much of my adult life creating an imaginative environment filled with adventure for my family.

"I have decided the timing is ripe, after 30-plus wonderful years, to hand over the reins to the next owners of this magnificent property to plant some roots of their own and watch them grow.”

An outdoor enthusiast’s dream, the property also features expansive trails -- great for mountain biking, motocross and all-terrain vehicle activity -- several acres of greenspace and seven bridges.

And of course, there is the family's famous pumpkin patch.

Matt said he plans to build another home on the remaining land, and will continue to grow pumpkins on it as well.

He added he would split his time between the farm and his home in Arizona, with his girlfriend Caryn Chandler.

"It’s too much now that I’m 60,” Matt told the WSJ. “I want to start to scale back a little bit.”
