Latest property data by Core Logic has revealed the city's average length of home ownership currently sits at 10.1 years for houses, representing an increase of 2.5 years over the past decade.

Factors contributing to Wagga's increase include TV shows which demonstrate budget-friendly renovations as well as effects following the Royal Banking Commission.

John and Ruth Lennon have lived in their home, situated near the Botanical Gardens, for almost 60 years.

The pair moved into the home in 1959 and Mr Lennon said due to recent health reasons, they have only started to consider alternative living options.

"We're thinking about it now because we're both in our 80s and I've had a few health problems and also the fact that we live on a slope on a hill," he said.

"We've given moving a bit of thought, but that's as far as it's gone at this stage.

"We have a son in Albury who has said to come live with him, but we don't want to, and we have a daughter who lives in Bendigo, which would be nice but we've got our roots here in Wagga and I think that's where we want to stay."

Mr Lennon said they have loved living in the area and it was the perfect place to raise his family.

"You couldn't have asked for a better area when the kids were growing up," he said.

"Our kids have all grown up and now there's been a full turn of the wheel in our area, with young ones all living in our street."

The data shows that the national average home ownership length is 11.3 years, which is an increase of 3.8 over the past 10 years.

The national data suggested that home owners are much more reluctant to sell their property than they were a decade ago, highlighted by the ongoing decline in sales transactions.

Other factors, such as the rising cost of selling and purchasing property, combined with affordability constraints across some of Australia's more expensive capital cities contributes to owners holding onto their properties longer.

However, Wagga's LJ Hooker sales consultant Jason Pearce said the factors contributing to this increase were different than the national figures because Wagga is more affordable.

"There's a couple of reasons; the rise of renovation shows have encouraged more people to renovate their existing properties," he said.

"The banks are also playing a part because it has become a lot harder to get finance and it's easier to get money for a renovation rather than selling and upgrading."

Mr Pearce said metropolitan investors are investing in the local market because it is cheaper and stamp duty is a large inhibitor.

"[Investors] don't mind turning over stamp duty, which hasn't properly adjusted to pricing over time - it's tied to the value of properties and as prices rise, so has the stamp duty," he said.

"Our market also has a high rental percentage so investment properties are long term, which would also have an extra effect on our market."

The Wagga council area was among the top 20 regions across the country that held the longest average periods for units across the country, at 12.1 years, while the national sits at 9.6 years.

Mr Pearce said the city's higher average was likely because there are less units in Wagga compared to major cities.

"This is probably because older people are making that transition into townhouses or units rather than retirement villages, because there's not as much choice," he said.
