REWRITTEN MESSAGE: Calculate the profit for 31 Keppel Bay View, #xx-xx if sold at $2.1 million and bought during launch.

To calculate the profit for a unit at 31 Keppel Bay View, #xx-xx in Reflections at Keppel Bay, you need to consider the following:

Purchase Price

During the launch, the prices at Reflections at Keppel Bay varied, but for simplicity, let's assume an average launch price. According to historical data, units at Reflections at Keppel Bay were sold at an average of around $1,000 to $1,500 per square foot (psf) during the launch period.

Unit Size

You mentioned the unit is at #xx-xx, but you didn't specify the size. However, for a typical calculation, let's assume an average size for a unit in this development. For example, if the unit is approximately 1,400 square feet (a common size for some units in this development), and assuming a launch price of $1,200 psf, the purchase price would be:
[ \text{Purchase Price} = 1,400 \text{ sq ft} \times $1,200 \text{ psf} = $1,680,000 ]

Sale Price

The unit was sold at $2.1 million.

Additional Costs

You should also consider additional costs such as stamp duties, legal fees, and any renovations or other expenses. However, for simplicity, let's focus on the basic calculation.

Profit Calculation

[ \text{Profit} = \text{Sale Price} - \text{Purchase Price} ]
[ \text{Profit} = $2,100,000 - $1,680,000 = $420,000 ]

This calculation does not include additional costs, but it gives you a basic idea of the profit made from the sale. For a more accurate calculation, you would need to subtract any additional expenses from the sale price.
