Houses with swimming pools and escape tunnels, a large ranch and an apartment where a cartel leader was killed are all up for sale.
Mexico’s President Andres Manuel López Obrador had pledged that profits from the auction would go towards those affected by drug gang violence.
But only nine of the 27 properties on offer actually sold.
Mr López Obrador said that the money would help poor and marginalised communities in the violent state of Guerrero.
At the end of May, a similar auction raised $1.5m by selling the homes and cars of criminals, including at least one former politician. A Lamborghini was among the items on sale.
Authorities said many more auctions would take place over the coming months.
Mr López Obrador, who was elected last year, has also promised to sell his presidential plane to fund efforts to curb illegal migration.
