Three resale HDB flats have recently breached the $900,000 mark.

An HDB executive apartment at Block 148, Mei Ling Street, was sold for $900,000 last month, according to resale statistics from HDB's website.

Over in Bishan, an HDB executive maisonette sold for $900,000 last month.

And a five-room flat at Upper Boon Keng Road was transacted for $903,000 last December.

These prices are not too far behind that of a HUDC flat in Shunfu Road, which sold for $1.1m two years ago.

However, property experts told The New Paper that these prices are exceptional and not representative of current HDB prices.

The Bishan unit is on the 20th storey of Block 173, a point block at Bishan Street 13.

Its seller, Mr David Siah, 42, and his family of four have been living there for the past four years.

His unit is about 1,600 square feet wide and its lease commence date is 1987.

Mr Siah, who works in the software industry, first put his flat up for sale last October.

While its valuation price was $740,000, he was confident the unit could fetch up to $950,000.

He had paid $610,000 for it in 2008.

He cited the location and view as reasons for his initial asking price.

"There's a new condominium being built right now and you can get a great view of its sky garden from my place," he said.

The condominium, Sky Habitat, is designedby architect Moshe Safdie, who is behind the Marina Bay Sands integrated resort.

It was earlier reported that prices range from $1,700 to $1,800 per square foot (psf).
