Daniel Sebastian Allen, 32, from Doon Road near Derrylin, changed his plea as his trial was about to start.
He admitted the murders of Roman Gossett, 16, his sister Sabrina, 19, and Sabrina’s 15-month-old daughter Morgana Quinn.
But he denied murdering Denise Gossett, 45, and instead admitted manslaughter by reason of a suicide pact.
Craigavon Crown Court was told that plea was acceptable to the prosecution.
Allen’s voice broke as he pleaded guilty to a fifth charge of arson with intent to endanger life.
The fire happened at a cottage the family were renting just outside Derrylin on 27 February 2018.
Allen had been living with the family at the time.
When the emergency services arrived he was standing outside and four bodies were discovered inside.
Allen had previously denied murder and claimed he did not play any part in the deaths of Roman and Morgana.

The judge said: “Since you have pleaded guilty to three counts of murder I now sentence you to life imprisonment.”
A defence barrister said: “Obviously these are serious matters and reports will be required.”
In addition to a pre-sentence report, he said time would be required for a number of other professional reports.
A sentencing hearing was set for 15 September when the judge will set the minimum number of years before Allen can be considered for release.
He will also be given prison sentences for manslaughter and arson.
Allen nodded as the judge told him he would serve life imprisonment for three murders before he was led from the dock in handcuffs.
