The investment is only good if the actuarial tables prove to be correct. For a counter example see: http://en.wikipedia.org/wiki/Jeanne_Calment http://en.wikipedia.org/wiki/Jeanne_Calment In 1965, aged 90 years and with no heirs, Calment signed a deal to sell her former apartment to lawyer André-François Raffray, on a contingency contract. Raffray, then aged 47 years, agreed to pay her a monthly sum of 2,500 francs until she died, an agreement sometimes called a "reverse mortgage". Raffray ended up paying Calment the equivalent of more than $180,000, which was more than double the apartment's value. After Raffray's death from cancer at the age of 77, in 1995, his widow continued the payments until Calment's death.
