These retirees ditched their pricey life in Santa Cruz, Calif. and now live on a lake in Mexico on $1,750 a month

Want to retire early? This FIRE couple they retired at 38 in 1991 share their secrets.

By their mid-30s, Billy and Akaisha Kaderli, now 66, seemed to have it all.

Billy was a successful stockbroker, and Akaisha ran a popular restaurant. They went out to eat and drank nice wine; hosted parties; and lived in a posh home in Santa Cruz, Calif., with a hot tub, garden and huge redwood deck that Akaisha calls her dream home. But they barely got to see one another as both had long, but different, hours, with Billy getting into work early and Akaisha working nights. We were burned out, Akaisha explains. Billy adds: I started to wonder how much longer I could continue on that treadmill.

And thats when Billy had an idea: As a stockbroker, hed seen his clients traveling and retiring and had a sense of how much money this took. He started thinking that maybe he and Akaisha could do it, too if they sold their home, the restaurant and their cars, scaled back their lifestyle and moved somewhere inexpensive.

I started penciling in the numbers, says Billy, who is a proponent of the 4% rule. The big question was, how much is enough to live on?

For the next two years the couple meticulously tracked their spending and the crunched numbers on inexpensive places to live. In 1991 after selling their major assets and investing that money they retired at the age of 38, and have lived abroad on about $30,000 a year since that time, they say. (They now receive Social Security, but before that they lived off the proceeds of their investments.)

Heres what its like, for the Kaderlis, to live abroad, what it costs, the challenges faced, and more.

Their philosophy for keeping living costs low: Geographical arbitrage

The Kaderlis have lived in Thailand, Guatemala, Vietnam and Ecuador, among other spots. They pick where they live based on a lot of things, like great weather, where they can learn a new skill (Thai massage, anyone?) and where there are interesting volunteer opportunities, but cost is the biggest factor. I call it geographical arbitrage, says Billy. We pick places where money goes far and quality of life is high.

For the past couple of years, the couple has been living in the Lake Chapala area of Mexico (this is their second stint living here). Its a spot popular with expats thanks to average temperatures between 75 and 85 degrees Fahrenheit (National Geographic rankedthe climate the second best in the world), proximity to a gorgeous waterfront (the lake is the largest freshwater lake in Mexico) and a friendly, laid-back vibe. Its also a little over a half hour from Guadalajara, Mexicos second largest city, which has an international airport.

Its low cost of living doesnt hurt: The Kaderlis spend about $1,750 a month to live here, they say. Their biggest expenses, besides travel both still go back to the U.S. once a year or so, and they take mini-trips throughout Mexico are rent and food. They pay about $300 a month for their apartment. They spend about $200 to $300 a month on groceries and add that they can easily match that amount if they are dining out a lot or entertaining. They keep food costs down because Billy, who is a French-trained chef, cooks most of their meals.

Though they live on a modest budget, Akaisha says they dont feel deprived. Weve lived in paradises all over the world thats our entertainment, she says. Plus, she adds, weve never been big consumers. We dont have all the doodads that people have.

And now that theyve become permanent residents of Mexico Billy says the process took about six weeks and required some annoying bureaucracy but wasnt too bad they get senior discounts on first-class buses and free admission to many museums and parks.

The Kaderlis have taken many different approaches to health care through the years, depending on where they lived, including what Akaisha calls going naked. (Thats her term for having no U.S.-based health insurance and instead relying on savings to pay for procedures as they need them.) They once had to pay about $3,000 in out-of-pocket costs for health care in Guatemala when Akaisha badly hurt her finger getting off a bus. (They said the care was good, and her finger is fine now.) Theyre now enrolled in Medicare so they could get care in the States if they needed it, but Akaisha says that theyve never used it.

Akaisha and Billy say that people often wonder if their current town in Mexico is safe, because they see headlines about crime in Mexico. But Billy says they havent had an incident as they travel about via public transit. But, he concedes, some of the border towns are rough.

There are other downsides to the area, the couple say. You cant drink the tap water: We have 20-liter bottles of drinking water delivered as needed with a phone call, says Billy. Other downsides: Loud culture with parades, music and cojetes [or firecrackers] going off often, he adds, as well as increasing traffic as more and more North Americans [are] moving into the area.

If youre wondering whether the Kaderlis are able to fill up their days without the help of a full-time job, it sure seems that way. Theywrite a website about their lives, have authored a book on retiring early, and have volunteered all around the world. Akaisha has taught the locals in Chapala to do Thai massage; Billy coaches and raises money for local sports teams.

And even when theyre not doing one of those myriad things, we keep busy, says Billy. We wake up in the morning with nothing to do, and at the end of the day we only have half of it done.
