Residents of Met-owned flats are given eviction notices
Eviction notices have been served on a group of residents in south west London - many of whom are nurses and teachers.
Their properties are owned by the Met Police which is selling them to help raise money for front line policing.
But the families in Merton say they will be made homeless and are urging the Mayor of London to stop the sale of the buildings.
They blame Boris Johnson for deciding to sell the flats in Griffith Road and Raynesfield.
The Mayor's Office for Policing And Crime (MOPAC) defended the sale.
In a statement a spokesman for MOPAC said: "The sale of both of these properties is part of the biggest restructure of the Met estate in 50 years and all of the money raised will be pumped back into front line policing right across the capital.
"Neither of these properties are yet on the market and we would consider proposals put forward by the residents."
The MOPAC statement explained that residents "have known of our intention to sell for many months".
Natasha Harris, a caretaker at a local school, has lived in the flats for 20 years and was told about the eviction two years ago.
She said average rents in the area were too expensive for her.
She said: "I have a couple of weeks left now until 4 November with still nowhere to go.
"Being a caretaker of the school I need to be within a distance of getting back to the school.
"It's been hard, it's been stressful. Losing sleep because you don't know where you are going or when it's going to happen."
Housing association Crown Simmons, which rents out the properties on behalf of the Met, said it did not have the vacancies to meet demand for rehousing everyone in areas in which they would like to live.
A spokesman said: "Although we have no responsibility for rehousing any of the residents, each year we have worked with the families and residents to identify what re-housing options are available to them."
