(We're not desperate to sell) With being new to the selling side, I'm curious what is standard for agent commissions in an off market situation.

Here is the key: Don't pay for anything until it's done to your standard.

In my market, I only have one vendor qualified for appliance warranty work, and the warranty companies paid him half his standard fee for each service call. 

The rules and payment standards vary significantly from one area to another, so familiarizing yourself with the local housing authority's procedures is key.

By fostering relationships instead of only chasing transactions, I’ve been able to tap into unique deals that helped me expand my portfolio without exhausting my resources.Relationships Across Borders: International and Out-of-State VenturesExpanding my network didn’t just open doors locally; it allowed me to explore international and out-of-state investments as well.

Best way to understand this is research appraisal standards and means. 

I guess to get a definite answer I'll have to cold call to get see if all these people are behind on their payment or it's just a standard practice behind some salesmen!

This motivation lead me and a business partner to start Raise the Standard Property Management.

@Connor O'Brien CHA does release payment standards that can be found on their website but those are maximums, not guaranteed.
