The three men, Yang Chao, Zhou Qifa and He Jiao, conspired to target vulnerable properties in Singapore, break into the houses, steal valuables and leave the country with them.
Both Yang, 42, and He, 38, were sentenced to five years and three months in prison, while Zhou, 37, was sentenced to five years and five months in prison.
A fourth man, Zhou Yinggui, 36, is charged with similar offences, while another two, Hu Wen and Zhou Ji, remain at large.
Deputy Public Prosecutor Benedict Teong sought a sentence of five years and three months to five years and 10 months in prison for all three men, arguing for general deterrence.
They took steps to ensure that their actions would be difficult to detect and targeted vulnerable houses in locations with fewer passers-by or with no CCTVs, he added.
