Lenasia land fraudster Mandla Dlamini was sentenced to three years' imprisonment by the Johannesburg Magistrate's Court on Tuesday.
"After considering all the facts before the court, including the age of the accused, I am still of the opinion that imprisonment is the option," magistrate Elen Engelbrecht said.
"You are sentenced to three years, six months of which is compulsory."
It would be up to the director of correctional services whether Dlamini was then released, said Engelbrecht.
Dlamini, 75, a bricklayer, was convicted of two counts of fraud for illegally selling stands and promising to build houses for people in Lenasia and Ennerdale.
One of the complainants paid him a deposit of R17 000 to build a house, while the other paid R12 000.
