The body of 36-year-old Piotr Krowka, a Polish national, was found in a former parochial house on Glen Road in Maghera in April.
At the time of the murder, police said they believed Mr Krowka “was sleeping rough in the derelict property”.
A 17-year-old boy and an 18-year-old man are expected to appear before Magherafelt Magistrates Court on Wednesday morning for a first remand hearing.
Following the murder, police said Mr Krowka, who had been living in the town for a number of years, had suffered serious injuries to his head and body.
More than a dozen teenagers have been arrested for questioning by detectives over the brutal murder.
