The search for financial independence and retire early (FIRE) has produced many different playbooks over the years. Some Singaporeans take the traditional route, working as hard as they can in their twenties and thirties, keeping expenses low, and investing every spare dollar. Others focus on maximising their income early in their career, even taking jobs they hate, with the hope that a stream of passive income can eventually replace their earned income.
But what if there is another way to “retire” early without spending years squeezing every last cent from your lifestyle or trying to hit an ambitious investment target?
For some Singaporeans, particularly those without kids, the answer may be sitting in their HDB flat.
The Appeal of Geoarbitrage for Singaporeans Seeking Earlier Freedom
In a previous piece, I argued that Singapore is not well-suited to early retirement. We are a small and expensive island with few opportunities for domestic geoarbitrage. A young professional in New York can eventually move to a quieter, cheaper town when they retire. A software engineer in San Francisco can retire in a lower-cost rural area, or even in the area where they grew up. In Singapore, even if you live at the extreme ends of the country, your cost of living is still the same.
This is why overseas geoarbitrage can be a compelling option for some.
Geoarbitrage is usually framed as a wealth-building strategy: earn and invest aggressively in a high-income country, then retire in a lower-cost region to stretch your savings. But a recent Vulcan Post article reminded me that this concept can be applied in a more immediate way. The piece profiled a 26-year-old couple who left their jobs to travel. They are currently funding part of their lifestyle by renting out their condominium for close to S$5,000 a month.
Not everyone in Singapore owns private property. But it does raise a natural question: could a similar strategy work for a couple who owns an HDB flat?
Can HDB Flats Be A Source Of Passive Income For Singaporeans Who Are Based Overseas?
To determine whether an average couple can “retire” overseas based on rental income from an HDB flat, we will use a simple, relatable profile.
Consider a 35-year-old couple with no children.
HDB Mortgage: They bought a four-room HDB flat five years ago and have just reached their Minimum Occupation Period. The flat has an outstanding loan of about $200,000, which, on a HDB loan, works out to roughly $1,070 a month over the next twenty years. For simplicity, let us assume the couple pays this instalment in cash rather than CPF.
HDB Rental Income: Their Punggol four-room flat is able to fetch a rental of about $3,200 a month, which reflects recent median rents in the area. To keep the numbers realistic, it is also fair to assume that not every month of rent goes straight into their pocket. A one-month agent fee, plus another month set aside each year for maintenance, minor repairs, and occasional vacancy, reduces their net annual rental income to about $32,000. This works out to roughly SGD 2,666 a month.
Investment Portfolio: The couple also has $100,000 invested in blue-chip Singapore stocks and REITs. At a reasonable dividend yield of about 4%, this portfolio provides an additional $4,000 annually, or roughly $333 a month. It is not a large investment portfolio by FIRE standards, but it reflects what many dual-income couples in their mid-thirties might realistically have after five to ten years of working.
Taken together, this gives the couple about $3,000 a month in passive income before considering any side earnings or part-time remote work that they can still do while overseas.
The key question then becomes whether this amount is enough to sustain an early-retirement-style lifestyle in a lower-cost country.
Where SGD3,000 a Month Can Stretch Comfortably in Southeast Asia
A passive income of about SGD 3,000 a month does not go far in Singapore. Still, it can offer a comfortable early-retirement lifestyle in several Southeast Asian cities, where rents, food and other living expenses are generally much lower.
Thailand is a natural first option. In Chiang Mai or Hua Hin, long-term rentals for a modern one-bedroom unit typically range from SGD 400 to SGD 700. Daily meals cost a few dollars, and even with utilities and transport added in, a couple can live well on SGD 1,500 to SGD 2,000 a month. With a digital nomad visa, they can even work remotely legally in Thailand for additional income if they want.
Malaysia is even more familiar to Singaporeans. In Penang or Ipoh, a 2-bedroom condominium can be rented for SGD 700 to SGD 1,000, and groceries and dining are roughly half as expensive as in Singapore. A monthly budget of about SGD 2,000 – SGD 2,500 can provide a comfortable standard of living.
Cities in Vietnam, such as Da Nang and Ho Chi Minh City, may offer even better affordability. Modern apartments generally range from SGD 500 to SGD 900, and local meals are very affordable. A couple can live comfortably on SGD 2,000 to SGD 2,500 a month, with room for travel, leisure and other entertainment.
Indonesia varies by location, but outside the main tourist centres, monthly expenses can stay well below SGD 2,000. Even Bali becomes manageable once long-term rentals are secured outside the most popular districts.
The Trade-offs of “Retiring” Overseas on HDB Rental Income
While the numbers make this form of geoarbitrage attractive, it does come with real limitations. The most immediate issue is that once the couple rents out their flat, they no longer have a home base in Singapore. A short return trip can turn out to be surprisingly expensive. Even a modest hotel or serviced apartment can cost several hundred dollars a night, and a one-week stay could easily wipe out an entire month of their overseas living budget. Staying with parents or relatives softens this problem, but not everyone has that option.
Healthcare is another concern. The couple would not enjoy subsidised medical care overseas, and private insurance in many countries may not cover everything. A single hospital visit, or a chronic condition that requires regular treatment, can quickly undermine the feasibility of this lifestyle.
This approach is also not ideal for families with young children. Schooling becomes complicated. Local public schools may not be suitable, and international schools are often too expensive. Home-schooling is possible but demands time, structure and long-term commitment.
Cost is the final constraint. This strategy works because the couple bases themselves in lower-cost, developing countries. The same budget that stretches comfortably in Thailand or Vietnam would be insufficient in Europe, Japan, or Australia, where rents and daily expenses will be much higher and comparable to those in Singapore. The freedom to travel widely remains, but long-term stays in these higher-cost destinations would require a much larger portfolio.
