"Rental Surfing", a local service app used by potential renters, pays users to attend rental inspections, take photos and videos of the property and report back to them when the work is done.

One Airtasker user offered to pay $50 last year for a person to attend a rental inspection in Eastwood, at 2/9 Bristol St in Eastwood.

Another Airtasker user offered $80 for them to attend an inspection in Richmond on Wednesday at 4 p.m. because they were out of state and could not attend in person.

"I asked Airtasker to inform the rental agent that they were attending on my behalf to take a video of the flat rooms, features and conditions ...... and then leave my details with the agent on my behalf." One user wrote for their assignment to check out a rental property in Dulwich Hill." If you have an eye for the condition of the property, it would be ideal if you could let me know what you think of the flat!"

Data collected from Airtasker shows a 20 per cent jump in the number of users paying to help inspect rentals to increase their chances of getting a property.

The data shows that the average price of an assignment ranges from $40-$200 nationally, with the average price in NSW being $174.

Part-time property manager and caterer Natalie Padjan has carried out more than 50 inspections across Sydney for people who were unable to attend.

Ms Padjan, 36, moved back into her parents' home with her partner while the pair were building their first home.

She has earned more than A$3,000 from her side business since the start of the year and says she receives multiple invitations to inspections every week.

"The competition to get a rental is so fierce that some of the queues are insane. There are usually 50 or more people looking at properties, depending on the area."

Tim Fung, co-founder and CEO of Airtasker, said that the amount of money people get paid for conducting rental inspections on behalf of users depends on the number of inspections and the details required.

"It's a competitive market and with immigration soaring, this has significantly increased rental demand and tightened the market even further, so we're glad our community can rely on each other to help find the right property and hopefully take some of the pressure off."

The increase in the number of people using the service's app to take part in rental inspections has coincided with a growing number of investors profiting from listing their Airbnb properties in the high-demand lifestyle suburbs of New South Wales.
