People from outside Orange looking for investment properties can only look online but anyone planning to relocate can inspect Orange homes in person with a real estate agent.

A state government exemption for people with the necessary permit and COVID approvals will allow some Sydney buyers to share in what is considered the busiest time of the year for real estate sales.

Under the NSW Health orders people are allowed to travel from Sydney to Orange for the following reasons regarding real estate.

"People inspecting a potential new residence, but only if they have a genuine intention to relocate as soon as practicable (no investment properties). [And] people who are permanently relocating."

Just-released research by property analysts CoreLogic says in spring in regional areas there is an 11 per cent increase in listings and a 4.7 per cent increase in sales compared to the annual average.

Orange estate agents say there has been an increase in properties going on the market in the past two weeks ahead of the first spring real estate weekend this Saturday.

McGrath Orange director Josh Fitzgerald said Sydney buyers were looking at Orange properties, mainly online.

"There's lots of enquiries over the internet from Sydney buyers," he said.

"We're being inundated with local inquiries [too].

"In our office we've put up 12 properties in the last three weeks which is quite a few and there's more to come."

One Agency Orange director Ash Brown said sales had been strong despite the COVID lockdown.

"Last week we had one of our best weeks of the year. We got eight properties under offer in seven days," he said.

"I thought we might have had a break," Mr Brown said.

"We've got a lot properties coming on, 15-20 new properties in the next month to two.

"There's still a lot of people looking."

Century 21 Combined Orange director/sales Andrew Vogler said it would be an "interesting" season for real estate.

"Hopefully there is a lot more properties coming on the market," he said.

Mr Vogler said public open home days would not occur and all inspections would be by appointment.

He said current restrictions required people to stay in their own local government area.

He said limits on investment property inspections were also in place.

"The days of people coming from Sydney to look at investment properties are gone," he said.

According to realestate.com.au there are about 175 properties for sale in Orange now.
