The Tews have always lived fairly frugally and maintained side hustles for extra income.
A full-time financial controller, Mark did tax and accounting work on the side while Amanda worked as a part-time college instructor and taught private violin lessons.
Implementing detailed financial goals and frequent budget reviews, they were able to pay off $50,000 of grad school debt in less than two years.
Mark saved his starting bonus as well as $1,500 a month from his paycheck from May 2012 to January 2014, for a total of $35,000. He and Amanda saved a total of $15,000 from their side work and by January 2014, they had paid off their student loans entirely.
After climbing out of debt, they then focused on their emergency fund.
By May 2015, they saved $30,000 by tucking away at least $1,000 a month from Mark's paychecks, $8,000 from Amanda's violin teaching, and $7,000 from Mark's CPA work.
Once their emergency fund was in place (equal to six months worth of expenses), they worked their way toward saving $20,000.
They used the same frugal and side hustle tactics to build a $10,000 "spend fund" for foreseeable emergencies and an additional $10,000 to put toward their mini-retirement. They met their savings goals in December 2015.

Mark and Amanda had to put money toward extra costs like childcare, maternity leave, house projects, and a cancer diagnosis for Mark about six months before they left.
They were still able to save a little more than $1,000 a month, for a total of $15,000 for the year. Combined with the $10,000 from the previous year, they now had $25,000 in their mini-retirement fund.
In the first four months of 2017, they saved another $5,000 from Mark's paychecks and the couple's side hustles.
They also sold their house in Michigan for a $50,000 profit, which they plan to save and use for a down payment if they ever buy again.
In May 2017, they left for Nicaragua.
They went over budget, but still spent less than they would have in the US — an average of $4,000 a month compared to $5,000 a month back home in Michigan.
One of the reasons monthly costs were more expensive than anticipated were due to Mark's cancer diagnosis before the family left for their year abroad.
Mark was uninsurable on international insurance plans, so he had to pay $500 extra a month for his COBRA plan, totaling $6,500.
Health insurance cost much less for the rest of the family.
They only paid $2,000 for a yearlong Latin American health insurance policy for Amanda and the kids. A consultation at the doctor cost $25.

The school they chose for their children didn't work out, so they ended up moving and enrolling them in an international school at $200 per kid a month, for a total of $800 a month.
Mark and Amanda reduced their housing costs by 36% compared to the US.
They originally reduced their monthly housing costs by 60%, from $1,250 a month in the US to $500 a month for a house in Nicaragua. But part of the way through their trip, they moved to be closer to the international school and their new house cost $800 a month. They had to buy furniture for the first home, which they ended up donating to locals before they left.
Utilities payments for electric, water, and gas were roughly the same as in the US. They also purchased two prepaid phones and paid about $40 a month for Internet while in Nicaragua.
Mark said they put down security deposits on their home rentals, which they don't expect to get back.
They also spent money on household help in Nicaragua.
They had a housekeeper who came two days a week for four-and-a-half hours and paid her $2 an hour, which is double the typical pay for a maid in Nicaragua, Mark said. They also had a gardener, who charged less than $7 a week.
Cars and gas are more expensive in Nicaragua compared to the US.
Mark and Amanda spent $8,000 to buy a Jeep (plus $20 on a lawyer to help them buy the car), about $4 a gallon for gas, and less than $40 for a mechanic. They planned to sell the Jeep for what they bought it for, as many expats have done, but the tourism industry and economy took a massive dive due to political unrest by the end of their stay, Mark said, so they left the car with a trusted friend.
They spent more on food than they anticipated.
For food, the Tews shopped at a chain grocery store with imported items, which were often more expensive. It would have been cheaper had they stuck to the open air markets, Mark said.

"For someone like me who watches every penny, it was a bit painful to shift my mindset with regard to the additional expenses," Mark said.
"We could have absolutely done it cheaper, but the experience was worth the investment. We had to be willing to make financial adjustments to have the experience that we wanted. And I actually ended up working and growing my accounting business a bit more than I anticipated and was able to more than offset our unanticipated increase in expense with what I earned."
