The former black cab driver, 61, bought the one bedroom flat in April in 1981 and currently makes £861 a month by renting it out, the Mirror reported.
But Worboys, who is understood to have owned several properties, is now being forced into a mass sell-off of his assets.
The one-bedroom, ground-floor flat is situated in a “sought after residential development” in Enfield, according to the estate agent.
It has a refitted kitchen, a remodelled shower room and a garage, and has been lived in by the same tenant for 26 years.
Last month it was announced Worboys would be in jail for at least another two years as a Parole Board concluded he is not suitable for release.
He was given an indeterminate prison sentence in 2009 after being convicted at Croydon crown court of 19 offences, including one rape and several other sex attacks, against 12 women.
After serving 10 years of his sentence, the Parole Board had in January announced that he could be freed.
But the High Court overturned the decision following a successful legal challenge by two of his victims and London Mayor Sadiq Khan.
The flat is said to be the final property in Worboys’ portfolio.
