They are the best repeat customers I have so I treat them as such.  

Individualizing fees in any business is a good way to encourage disgruntled customers.

Worked with them multiple times with extra effort on their part to make sure customer was happy.  

I must say the responsiveness and customer service you guys provide is truly excellent.

I'm a Chicago and Southside investor (Landlord, flipper, broker, turn-keyer) and I'm familiar with Mack, but not as a customer strictly as an observer.  

Another possible pitfall with buying an existing business is the angry customer/vendor/tenant that just hasn't gotten around to suing or acting on it yet.  

Terminating a management agreement for cause is not necessary just because of poor customer service by the management company.

I've been using MySmartMove for background checks, PopMoney for rent payments and a custom google forms/docs for applications.  

I have an excellent crew that I have worked with at my current job, and the company has very high expectations for time, budget, and quality for our customers.

FL exemption to RE broker's requirement, per FL law: (2) Any individual, corporation, partnership, trust, joint venture, or other entity which sells, exchanges, or leases its own real property; however, this exemption shall not be available if and to the extent that an agent, employee, or independent contractor paid a commission or other compensation strictly on a transactional basis is employed to make sales, exchanges, or leases to or with customers in the ordinary course of an owner’s business of selling, exchanging, or leasing real property to the public.My 2 cents.
