One side note if you don't have representation getting a commission then you should negotiate the Buyer side commission out of the purchase price.  1st get the contract and agree on price paying the 3% commission on the Buyer side, then once the contract is signed you can amend the contract to back out the commission in the purchase price since that will not impact the Seller or the Listing Agent 99% of the time it will work just fine.

Plus the added bonus of a commission, or a reduction in purchase price.

It also appears the commission rate averages around 5.X% for my location where as normally they range for 6-7%.Let me know if you guys have used them and what you think.Thanks!

Realtor is "paid back" at closing...plus typical commission. 

There is one big advantage of working with a seller who has their home listed with a flat fee MLS company and it relates to commissions. 

The commission you charge yourself is one of your costs as selling as a consumer.

I know some of the better agents have minimum commissions, which you might not be able to meet if you're in the sub 100k market.

You also have to consider closing costs and realtor commissions, so I have to sell for at least $10K more than I owe and I owe about what the house is worth (maybe a little less).

What commission is typical / appropriate on a multi family block with a sale price of $ 3 million?  

If that doesn't work, ask your lawyer to file a complaint with the real estate commission that oversees broker compliance with the law.
