Robert Williamson, 2 Kintyre Place, Tamfourhill, pleaded guilty to entering the property in Carronview, Stenhousemuir on January 9, where he also struck a door and windows and shouted at a man and woman, aged 77 and 79 respectively.
He also failed to desist when requested to do so, made threats of violence and demanded money from a woman over the phone.
The 31-year-old then repeatedly called another woman on the same day and again insisted on being given cash before damaging her property.
Williamson committed the offences while on bail.
He had been due to appear at Falkirk Sheriff Court last Thursday, however, his defence solicitor said Williamson was currently self-isolating.
The solicitor pointed out the potential for a psychiatric report.
Sheriff Derek Hamilton continued the matter until March 11 for his personal appearance.
Bail was also continued.
