Are they easy to train ?

There is no wrong way to do this unless you aren't doing it at all OR you're harrassing peopleIf you find yourself attending a bunch of educational webinars, watching too many tutorial/training videos, or anything other than those 2 things, take some time to stop and reflect. 

Even if it appears your property is marketed at less than the competition, there could be something about it that makes it less desirable (busy street, near train tracks, no off street parking, run down neighbors, etc.)

They also live stream their networking meetings and weekly trainings to their Facebook page. 

You think that you hired a specialist and are paying for the corresponding quality, while in reality you might have some under-trained, unmotivated and unsupervised anonymous data entry clerk doing the work, full of costly mistakes and cut corners.Often, low-cost CPAs get overwhelmed with the amount of work they take, resulting in rushed poor quality product and mediocre (or worse) service.

These are professionals with additional training and a stricter code of ethics.

So I'm trying to learn everything I can as I search out my path to gaining the needed capital to get this train rolling. 

@Robert Rixer, I don't know how creative these are, as many are common plays:Valet TrashFencing in first floor yardsProviding washer and dryers for added rentReserved, Covered parkingTech PackagesInternet and Cable contracts, with reimbursementsPayment Plan rents, with small service charge (i.e. bill 1/4 rent each week)Reserved Rental cabanas at poolPrivate pool party rental optionGolf Simulator in clubhouse - fee basedOn site, self serve car wash (quarter feeder style)Charged group fitness/personal training servicesGame room in clubhouse with monthly subscription for tenants (Xbox, Playstation, etc)Changing out high maintenance grass for astro turf or lower maintenance/lower water use shrubberyBut ultimately, I think a lot of NOI increases come from deep dive into understanding EVERY expense and finding ways to minimize them, and/or no outsource them.Train maintenance team on basic HVAC and appliance repairs (find way to get them licensed as needed)Buy paint sprayers for faster, easier turns versus having to hire a contract painter, and possibly repaint whole unit each timeStandardize all finishes, so you can buy in bulk, everything from hinges and door knobs to cabinets, paint colors, and light fixtures.Potentially get leasing people onto lower base salary with higher bonus potentialBulk/bundled insurance across portfolio (even better at scale is to self insure)Regularly test sprinkler systems for leaks.Non-NOI, but benefit to you: partner with insurance agency to get referral kickbacks from your tenant base for renter insurance.  

Hardest thing to train real estate service providers on is when to turn down a client.

That is for people trained to buy property the correct way, but most people aren't trained so they resort to the aforementioned options.
