Police said they got a call about shots fired just before 9 a.m. in the 2000 block of Weaver Forest Way.
The dead were identified as Melissa and Jonathan Preston. The couple had three children who are now being taken care of by family.
The incident is still under investigation, but police have said there is no cause for alarm and they were not looking for suspects.
The Prestons were renting the home in the Providence Place neighborhood south of NC Toll 540 and west of Chapel Hill Road. Wake County property tax records show it's valued at about a half million dollars.
Next door neighbor Sunil Nigam told ABC11 he came out to see what happened after hearing police.
"One couple was in the driveway, so I just asked why the police were here, and they said there was some arguments," said Nigam.
Other neighbors said the Prestons had moved here from Seattle - had been here less than a year - and were about to move back to Seattle.
"Very peaceful, very peace loving people. We meet around. We have a kids carnival in two weeks in time. No, they haven't had any problem at all," said Ashish Tayal.
"They were very nice people. I have to say, very nice people. They were loving. They had three loving kids. The husband, wife, they were always working in the yard. Actually, they were ideal family, in my view," said Nigam.
Tayal said the kids - two boys and a girl - are about middle school age.
"Your heart goes out to the family, to the kids," said Tayal.
Neighbors say the Prestons had overnight guests in the home who told them the couple had an argument. Exactly how that ties into their deaths is still not clear.
