In summary, while it is difficult to predict exact future price movements, a well-maintained HDB flat in a desirable location like Sengkang could still appreciate in value over the long term. However, the rental-then-sell model should be carefully evaluated based on current market conditions, rental yields, and your personal financial goals. For the most accurate and up-to-date information, it is advisable to consult with a real estate agent or financial advisor.
