Properties at Bawnmore Road, Strangford Avenue, Glengoland Gardens, Deramore Park South and Riverdale Park South were said to have been targeted between midday and 8pm.
Belfast Magistrates’ Court heard a number of stolen items were allegedly recovered from the vehicle.
A detective claimed the accused are linked to the burglaries by witness descriptions and a glove found in the car matching one left at the Strangford Avenue house.
Referring to the break-ins, he said: “They related to elderly people.”
Entry was gained either by an unsecured door or by smashing window panels.
District Judge Mark Hamill was told one pensioner had returned home to find intruders in his property.
Bail applications by the accused were adjourned after Mr Hamill requested copies of any relevant records.
All four defendants were remanded in custody to appear again in court later this week.
