The Dilemma of Retaining Your HDB Flat While Owning a Condo in Singapore (2025)

Posted by Jayson Ang on June 23, 2026

TLDR

Singaporean citizens can own both an HDB flat and a condominium if the HDB was purchased first and after the 5-year Minimum Occupancy Period, but buying a condo after often incurs a 20% Additional Buyer’s Stamp Duty (ABSD). Generally, paying ABSD to keep the HDB flat is not financially advisable due to the long recovery time through rental income or appreciation. However, retaining the HDB flat may be worthwhile in specific situations such as providing housing for dependants, strategic condo rental generating positive cash flow, future plans to return to the neighborhood, or as a fallback security option. Alternative ownership schemes can avoid ABSD but aren’t always practical. Overall, keeping both properties despite ABSD is usually driven by personal or family needs rather than pure investment gains. Expert advice is recommended for tailored decisions on buying, selling, or waiting in Singapore’s property market.

For Singaporean citizens, the decision to hold onto their HDB flat after purchasing a condominium typically incurs a 20% Additional Buyer’s Stamp Duty (ABSD) – and even higher for Permanent Residents. While strategic planning, such as utilizing the owner-occupier scheme or acquiring a dual-key unit, might offer some workarounds, these options aren’t universally practical. This raises a crucial question for many: Is paying the ABSD a worthwhile investment to retain your HDB flat? This article explores various perspectives on this complex decision.

Clarification on Owning Both an HDB Flat and a Condo:

It’s a common query: can you own both an HDB flat and a condominium simultaneously? The answer is yes, provided the HDB flat was purchased first. After fulfilling the five-year Minimum Occupancy Period (MOP) for the HDB flat, you are permitted to acquire a private property. However, this incurs the prevailing ABSD rate for Singapore citizens (currently 20%). Alternatively, with meticulous pre-planning using schemes like the Single Owner and Essential Occupier approach, it’s possible to own both without incurring ABSD. It is crucial to remember that you cannot purchase a condominium first and then acquire an HDB flat.

Investment Perspective: Generally Advised Against

The prevailing sentiment among most property agents is that retaining an HDB flat for investment purposes, while incurring ABSD, is generally not a sound financial move. While the ABSD cost might eventually be recouped through property appreciation or rental income, agents often argue that the timeframe is excessively long, and there are likely more efficient uses for the capital.

One agent provided a clear illustration: paying a 20% ABSD on a $1.5 million resale 3-bedroom condo or a $2.2 million new launch 3-bedroom condo amounts to $300,000 and $440,000 respectively. Assuming a gross rental income of $3,500 per month from the HDB flat (equating to $42,000 annually before deductions for taxes, maintenance, etc.), it would take over 7 years to recover the ABSD for the resale condo and approximately 10.5 years for the new launch condo. After accounting for recurring costs, this recovery period could extend to 8.5 years and 12.5 years, respectively.

The agent concluded, “It seems pretty pointless to me. It will basically knock you back by 10 years’ worth of savings; even a fixed deposit would be better.” Another agent opined, “You take the rental money to pay the mortgage so there’s a feel-good factor, but the money is still gone. Or you wait for the property to appreciate, but then the gains are just covering the ABSD in the end. Why go through that hassle for years? You’re better off staying put in the HDB flat, and having cash in hand.”

Agents also caution that renting out an HDB flat is not as passive an income stream as many homeowners anticipate, involving responsibilities like tenant sourcing, vetting, and rent collection. They suggest that saving the ABSD amount and investing it in less burdensome assets might be more prudent.

Situations Where Retaining the HDB Flat Might Be a Good Idea:

Despite the general financial reservations, there are specific scenarios where retaining the HDB flat, even with ABSD, could be beneficial:

Providing for Dependants: One compelling reason is to provide housing for a dependant, such as an adult child or aging parents, who require independent living arrangements. For example, a client might absorb the ABSD cost to allow their newly married daughter to live in a familiar HDB environment, easing her transition without the need for rental. Another homeowner chose to keep his flat even when his parents moved in with him, providing a separate fallback option for either party should cohabitation become challenging in the future. A dual-key condo unit might also serve this purpose.
Strategic Condo Rental: Some homeowners strategically purchase a condo with the primary intention of renting it out, while continuing to reside in their HDB flat. This is particularly appealing if the rental income from the condo can immediately cover its mortgage, maintenance, and other associated costs, making it cash-flow positive. This strategy can be attractive to investors seeking a targeted income stream, such as meeting a desired Income Replacement Rate (IRR) for retirement, or those anticipating future income disruptions.
Future Relocation to the Area: Buyers who anticipate eventually moving back to their HDB flat’s familiar neighborhood, perhaps in retirement, might find value in retaining it. One homeowner, who paid 12% ABSD years ago, considered it a wise decision, as the cost of re-acquiring a resale flat in his desired, well-located area (Tampines) has significantly increased, potentially exceeding the original ABSD paid. This decision, however, hinges on the assumption that resale HDB prices will continue to appreciate at a pace that justifies the initial ABSD outlay, which is not guaranteed.
Security and Fallback Option: For some homeowners, the primary motivation is a sense of security. Knowing that they have their HDB flat as a fallback option, should unforeseen circumstances force them to sell their condo, offers immense peace of mind. This also mitigates the stress of simultaneously selling a private property and finding a replacement home, especially considering that selling a private property typically entails a 15-month waiting period before being eligible to buy a resale HDB flat (for those under 55). While this sense of security may not have a quantifiable monetary value, it is a significant factor for many.

Alternative Approaches:

For those exploring ways to own two properties without incurring ABSD, strategies like utilizing the Single Owner and Essential Occupier scheme or starting with a smaller 3-room HDB flat to ease into dual-property ownership are worth investigating.

Ultimately, the decision to retain an HDB flat while purchasing a condo, despite the ABSD, typically caters to very specific family needs, lifestyle preferences, or a desire for security, rather than being a purely financially driven investment. For personalized advice tailored to your unique housing situation, it is advisable to seek expert consultation.
