How did you arrive at the valuation of S$1.49 million for 31 Canberra Crescent #xx-xx?

To estimate the valuation of the unit at 31 Canberra Crescent #xx-xx in Provence Residence, we consider the recent transaction data for the development.

As of the last 12 months, the sale prices at Provence Residence have ranged from approximately S$1,454 per square foot (psf) to S$1,551 psf, with an average price of around S$1,512 psf.

Using the average price of S$1,512 psf:
- For a 1,000 sqft unit: S$1,512 psf * 1,000 sqft = S$1,512,000
- For a 1,100 sqft unit: S$1,512 psf * 1,100 sqft = S$1,663,200

Given these calculations, the estimated valuation for the unit at 31 Canberra Crescent #xx-xx would likely fall within this range.
