荃灣中心12年升值35％　一房336萬沽賺15萬

The search results confirm the transaction details and, importantly, provide the specific reason for the extra gain. The article states: “荃灣中心有原則一房原業主早前投資者買入但撻訂離場，原業主不但殺訂賺多15.8萬元，而即時加價22萬元最終以336萬元沽出，呎價10,370元。” It clarifies that the “一個原因賺多15萬” is due to a buyer defaulting, leading to the forfeiture of a deposit of 15.8萬元, and the unit subsequently being relisted at a higher price (originally 338萬, sold for 336萬). This confirms the core details and provides the missing ‘reason’. I can now integrate this factual reason into the report.

Now, I can proceed with the plan, incorporating the specific reason for the additional gain.

Plan refinement:

Engaging introduction.

Section: 回顧十二載：物業升值的歲月印記 (Recalling twelve years: the mark of property appreciation). Discuss the 12-year holding period and the overall 35% gain, putting it into market context.

Section: 意料之外的「額外獎勵」 (Unexpected ‘extra bonus’). Detail the initial sale, the buyer’s default, the forfeited deposit (15.8萬元, which is close to the 15萬 mentioned in the title), and the subsequent re-listing and sale at a slightly higher price. Explain how the forfeited deposit contributed to the extra gain beyond the capital appreciation.

Section: 市場波動中的靈活應對 (Flexible response amidst market fluctuations). Analyze the seller’s decision to re-list and slightly increase the price after the default, suggesting market responsiveness.

Section: 從個案看啟示：長線投資與風險 (Insights from the case: Long-term investment and risk). Discuss the lessons learned, emphasizing that while long-term holding can yield significant returns, unexpected events (like buyer default) can also influence the final outcome. The forfeited deposit highlights a risk for buyers but a potential unexpected gain for sellers in certain situations.

Powerful conclusion summarizing the key takeaways.

Ensure language, structure, and formatting meet all requirements.

Character count check.

The forfeited deposit is 15.8萬元, which aligns perfectly with the “賺多15萬” narrative in the title (likely rounded for simplicity in the headline). This is the key factual detail to incorporate for the ‘one reason’. The unit is 荃灣中心4座中層H室, practical area 324 sq ft. The original purchase price was 247.5萬元 in 2013. Sold for 336萬元. Profit: 336 – 247.5 = 88.5萬元. Percentage gain: (88.5 / 247.5) * 100% = 35.79% (rounded to 35% in the title). The forfeited deposit was 15.8萬元. The unit was originally agreed to be sold for 316萬元, but the buyer defaulted. The owner then re-listed at 338萬元 and sold for 336萬元. The total gain from the original purchase to the final sale + forfeited deposit is 88.5萬 + 15.8萬 = 104.3萬 (this is not directly stated as total profit in the article, but derived from the details). The article states the unit appreciated by 88.5萬元. The ‘extra 15萬’ gain likely refers to the 15.8萬 deposit on top of the original agreed sale price gain (316萬 – 247.5萬 = 68.5萬 profit before the default) OR simply the forfeited deposit itself as an unexpected gain on top of the capital appreciation. The article explicitly states the owner “不但殺訂賺多15.8萬元，而即時加價22萬元最終以336萬元沽出”. This confirms the forfeited deposit is the “賺多15萬” part. The overall profit is 88.5萬元 based on the final sale price of 336萬元. The title’s “賺多15萬” refers to the additional money gained *because of a specific reason* (the default), not necessarily added to the 35% profit calculation in the headline, but as a separate component of the total financial outcome for the seller in this specific sequence of events. I will explain this sequence.

Okay, I have the facts and the structure. I will focus on presenting the information clearly and engagingly, adhering to all constraints.
