On Tuesday this week there were about 70 houses, units and townhouses available for rent in Orange according to the Domain and realestate.com property websites.

National property research company Propertyology highlighted Orange and Dubbo among 48 cities across Australia facing a rental property squeeze.

Head of research Simon Pressley said just four cities surveyed, including Sydney, had more than the acceptable three per cent vacancy rate of properties for people to rent.

"With one of Australia's lowest unemployment rates, Dubbo has an incredibly tight one per cent vacancy rate," he said.

"It's a similar situation for Orange (1.2 per cent) where the median house price increased by 38 per cent and median rents are up 15 per cent over the last five years."

Mr Pressley said it would lead to rents going up.

"The only thing currently preventing an official declaration of an Australian rental crisis is the sedation effect of the coronavirus containment measures. Mark my words, sharp rent rises are inevitable," he said.

Century 21 Combined Orange director Andrew Vogler said rental properties were in high demand.

"The prices have been increasing," he said.

He said about 8-10 groups of people had inspected a Thomas Street property at its first viewing on Tuesday.

Mr Vogler said they would also be filming the property for potential renters from Sydney to inspect.

He said there was increasing demand from people in Sydney looking to rent in Orange.
