Yvonne Davies, 46, was found stabbed in the kitchen at the property in Meadway Road, Cheadle Hulme, on Friday.
Post-mortem tests found she died from multiple stab wounds and Andrew Davies, 45, was deemed to have died of asphyxiation due to hanging.
Paying tribute, Ms Davies's family said they were "heartbroken".
"Yvonne was a wonderful wife, mother, sister, daughter and friend.
"She had a successful career but still managed to be a devoted mother who raised an amazing, beautiful daughter who is an absolute credit to both her parents."
Ms Davies was a magistrate at Manchester Magistrates' Court and head of communications and PR at the Central University Hospitals Trust in Manchester, where she had worked for more than 20 years.
Greater Manchester Police said they did not believe there was any "third-party involvement" in the deaths.
A statement from Mr Davies's family said he was an "incredibly loving father who took five years out of work to spend time caring for his daughter.
"What happened that day was totally out of character for Andrew and none of us, family or friends can believe what has happened.
"Our hearts go out to Yvonne's family, we are devastated for them."
Mr Davies's family also said:  "We are also heartbroken for our niece Emma, who has lost two loving parents."

Goodes, an Indigenous Australian, is regularly jeered and racially abused by spectators.
The #IstandwithAdam campaign was trending on Saturday, with actors like Cate Blanchett offering their support.
Some fans have defended the booing, claiming it is not racist, but simply a response to Goodes' performance.
Ms Blanchett and other high-profile figures, like actor Hugo Weaving and opposition leader Bill Shorten, have spoken out in support of the 35-year-old footballer.
They sent videos to Fairfax Media backing the #IstandwithAdam campaign.
During games Goodes has faced derogatory slurs and even been told to "get back to the zoo".
Other Twitter users said the success of a native Australian should be celebrated rather than derided.
The Sydney Swans star has described the abuse as "shattering" and is taking time off from the sport.
Australian Rules football, or Aussie Rules, is played on an oval pitch, between two teams of 18 players.
The Australian Football League (AFL) Players' Association and team skippers released a statement on Friday expressing their distaste for the constant booing, especially during last Sunday's clash at Perth's Subiaco Oval.
"Enjoy the game, celebrate the success but don't boo, jeer or taunt players because of who they are or what they stand for," it said.
Goodes is a vocal advocate for indigenous issues and wants to see Aboriginal people recognised by the Australian constitution.
Others, including cricketing legend Shane Warne, have defended fans' right to boo athletes.
"For me, I don't think that the stuff that they're doing to Adam Goodes is racist," he told Triple M radio station.
"It's their prerogative. Australia can have an opinion."
Separately, one of Australia's wealthiest and most influential businessmen, Crown chairman James Packer, said on Friday he was "ashamed" of the whole affair.
"He's a great Australian. He won Australian of the Year, I think he's an amazing role model," local media quoted Mr Packer as saying.
