The latest figures provided to Orange City Council show the median rent for a house is now $410 a week - up by $10 on the previous month.

And figures from property website realestate.com.au show there were just 41 properties available for rent on Monday morning this week in the whole 2800 postcode area.

The average cost of a two bedroom house is steady at $320 a week, a three bedroom house is up $10 on the previous month to $390 a week while renting a four-bedroom house is up $15 a week in a month to $475.

Units rentals varied from $260 a week for a one-bedroom property to $310 for a two-bedroom unit and $395 for a three-bedroom unit.

Employment and training group VERTO says its tenancy advice service has seen a 228 per cent increase in Orange tenants contacting them over being able to afford rent increases in the past year.

VERTO CEO Ron Maxwell said the increases were "simply not manageable or sustainable" for many tenants.

"Many are still feeling the financial impacts of COVID-19 and may already be in rental arrears. The consequences of being unable to afford housing are significant and include ongoing housing instability and/or homelessness," he said.

Mr Maxwell said rental vacancies in the Orange and Bathurst areas were down to as low as 0.6 per cent in some areas.

"When you have a situation where rents are rising, and it's incredibly difficult to find new housing, you unfortunately have a perfect storm for many tenants," Mr. Maxwell said.

Mr Maxwell said there had also been substantial increases in leases being terminated without reason.

He said No-Grounds Termination Notices were up by 144 per cent in Orange.

Mr Maxwell said one in three tenants who sought assistance from VERTO's Tenants Advice and Advocacy Service had received one of these notices.

"Anecdotally, our team are reporting increased anxiety among tenants when it comes to requesting maintenance or repairs, worried that the request may lead to a no-grounds termination," he said.

"This is a concern as we approach the winter months, and heating becomes a necessity," he said.

"Housing instability, or fear of it, can have a raft of social impacts, particularly for some of the most vulnerable in our community," he said.

"For those experiencing domestic violence it may lead to a difficult choice, staying with a perpertrator or sleeping rough, a choice no one should have to make."
