At the High Court in Glasgow, David Hobson pled guilty to murdering his 42-year-old uncle Gary Logue in a flat in Elderpark Street, Glasgow, on February 23 and then dumping his naked body.
Hobson is facing a life sentence and temporary judge Sean Murphy, QC, will this month decide how long he stays behind bars before being eligible for parole.
Advocate depute Andrew Brown, QC, prosecuting, said: "There seems to have been past tension within the family following the alleged theft of money by Mr Logue from his mother's house while she was in hospital in 2010. Savings of £400 were taken."
Meanwhile, a man whose kicks and stamps inflicted "catastrophic" brain damage on his uncle was jailed for eight years.
William Johnston, 47, is in a "persistent vegetative state" and is expected to be so for the rest of his life.
Sentencing Steven McMahon, 32, at the High Court in Edinburgh, judge, Lord Brodie told him: "This is a case where you showed extreme violence which has had catastrophic results."
Father-of-six McMahon of Edinburgh, denied a charge of attempted murder – claiming self-defence.
A jury rejected McMahon's claim and found him guilty of assaulting Mr Johnston to the danger of his life in Calton Road, Edinburgh, last August.
