The Gulf War in the early 1990s drove Dr Cheng Eng Wah's belief that property investments were the way to go in Singapore.
The war, over Iraq's invasion of Kuwait, caused some serious stock market turmoil, but he noticed that the property market here was less affected.
Dr Cheng, 51, a dentist, bought two landed properties shortly after the war, confident that their values would appreciate over time despite the prevailing mood of uncertainty.
With financial help from his parents, he bought a semi-detached house and a terraced house.
He remains a firm believer in property and stresses the importance of timing the market and getting a unit close to the MRT.
"The three properties my wife and I own are close to public transport networks," he says.
He was one of the first dentists here to embrace "invisible" teeth straighteners Invisalign - an alternative to traditional metal braces.
Dr Cheng has been appointed to run an Invisalign Centre of Excellence in Singapore by the parent company in the United States.
"That investment will cost about $500,000, but I'm confident that it will catch on with Singaporeans," he says of the straighteners.
"About 46 per cent of Singaporeans are born with crooked teeth and most of them are fearful of the pain associated with wearing traditional braces."
The Invisalign straighteners are transparent and can be removed when eating.
