Twenty years later, Lee bought Dunlop Estate. In 2008, he recalled the happiest day of his life in an interview with the New Straits Times, saying, "My happiest day was in 1989 when I bought Dunlop Estate from Multi-Purpose Holdings Bhd. This was because during the late 1960s, I had applied for a job at Dunlop Estate but they did not employ me because I was not adequately qualified. If they had employed me, I would probably not have owned the entire asset of Dunlop Estate today. This purchase marked a significant milestone in my life".
