With the rental crisis not expected to ease anytime soon, more Australians are entering into share-home arrangements.

Flatshare.com.au, which introduces flatmates and house sharers to each other, says it has experienced an increase in people looking for a share house or flat.

Flatshare community manager Claudia Conley says there has also been an increase in people aged over 55 looking for a spare room in an established house and homeowners looking for lodgers.

She says 68,000 people registered on the website in January and there has been a 20% increase in activity in the past year.

Conley believes there are 12 million empty rooms in Australia.

With growing demand for sharing accommodation, it’s thought some investors may explore letting their property as a flat share rather than a single tenant lease.

The sharing trend is set to continue for the next few years, as rents rise, mortgage holders face higher interest repayments and the supply of affordable housing is sluggish.
