These 3 investors bought an abandoned high school for $100,000 and turned it into 31 luxury apartments. Take a look around.

The project was on hold for about a year after the trio purchased the school, as they couldn't agree on what to do with the building.

"We were talking to some larger tenants — a gymnastic crew, a basketball crew, renting out rooms for a recording studio," Colucci said.

They eventually decided to turn the 55,000-square-foot building near Pittsburgh into a residential complex.

It took them about 18 months to complete and cost around $3.3 million, according to Wig. They put $1.3 million in themselves and also secured a $2 million mortgage, he said.

"The beauty of this building was worth what we paid," Colucci said.

The trio were only able to use about 20,000 square feet of space, Colucci said, as areas including hallways, staircases, gym, and auditorium had to be preserved.

They turned most classrooms into individual apartments, while dividing some of the larger ones in two.

"I'm really happy we did it this way because the building's so cool," he said.

The trio reused some of the original materials from the school, such as the hardwood floors from the old auditorium.

"Preserving the history and reusing the old windows was very challenging," Colucci said.

Spanovich said he sourced all the materials needed, and that sometimes his stress levels were "off the charts."

"The really tall ceilings and the large windows and a handful of other features are cool," said Wig, a 35-year-old real-estate agent and investor.

But the real "wow" factors are the auditorium, the gymnasium, big hallways, and the crown molding, he added. "The building is just unique."

Rents ranges from $1,150 to $1,450 a month, Spanovich said.

The apartments are equipped with stainless steel appliances, built-in washing machines and dryers, and walk-in closets.

Residents also have access to common areas such as the auditorium, which has a shuffleboard, a TV, and a lounge area.

The building also has additional storage available to rent to store items such as bikes or sporting equipment.

The trio have since bought another school.

"Maybe I'm just a dreamer, but I knew as soon as we had that first building that we needed that second one," Colucci said.

They acquired the second building, which is across the street from Bowtie High, for $90,000, he said.

It was in a worse state and needed a lot more money spent on it, but he said they "had to get it."

Spanovich said he expects the trio to have spent $4 million on the renovations upon completion.

The second building will have a rooftop deck with outdoor furniture and a billiard table, and residents will be able to use amenities from both blocks.

"There's gonna be some good synergy," Colucci said.

It will have 33 apartments with the same 14-foot ceiling height as the original classrooms, and concrete floors, he added.

The apartments have attracted particular attention from young professionals or graduate students, Colucci said.

He added that they had a good mix of tenants but wanted to expand and diversify their customer base further.
