Owners mistakenly ASSUME all PMCs offer the exact SAME SERVICES and PERFORM those services EXACTLY THE SAME WAY, so price is the only differentiator – so, they often select the first PMC they call or that calls them back!

@Moira Baggett it's hard to answer without knowing more specifics on what you define as a "failing" syndication investment. 

I searched but didn't find any specific referrals.

I am now prepping to sell a home for $1.1M to $1.2M, so I am planning to offer my selling realtor a max of 2%, and the buyer's realtor the same.

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

Does it make sense to offer an additional bonus (let's say 5K) if they are able to negotiate for $1.1MM on top of the usual 2.5% - 3%?

If it is due to the company either pulling out of the market or changing their guidelines that is best because it is not anything specific to your property. 

I have it in my lease specifically that even though utilities are "included" there are caps on the monthly amount I will pay and the tenant will be billed for anything above that amount.

I know laws are state specific, but any advice would help in case I need to foreclose.
