@Courtney McCall, I appreciate the motivation behind your post and where you are coming from.
I started my company from a similar perspective. I found that every property manager I encountered was a washed-up Realtor who couldn't hack it in sales and reluctantly resigned themselves to "slumming it" in property management. They are the ones who give the industry a bad name.
Fast forward 15+ years later and I find myself a landlord of many single-family homes and an owner of a property management company managing nearly 1,000 doors.
Without making this post a book to read, I want to remind you that time is money. I know no other industry where this is more true than property management. Every minute spent with a client comes with an opportunity cost. Your lofty ambitions of helping investors with every aspect of their rental property better come with a hefty price tag, or you will find yourself in the poorhouse.
I suspect you will quickly realize there is a ceiling on what owners will pay for property management. The "half assed rent collectors" you alluded to - while I don't advocate for that approach, and it's not what we do - have figured out that there is a market for exactly what they are doing.
The real question is, is there a market for what you're proposing?
I pay very close attention to the details of my firm. I pay attention to our competence, responsiveness, effectiveness, and other internal metrics. But I also look closely at minutes spent per door. If doors are over-utilizing our resources, we cancel management. Usually, a warning is provided first. This is a business, first and foremost, not a charity. Doors (or clients) that require extensive and constant attention from my staff are not long for this world and will be cut loose.
As @Richard F. mentioned, clients fall into those two categories (micromanaging, time-sucking parasites who place zero value on the value of your time, or the "don't bother me unless the house burned down" clients). Obviously, there is a spectrum, but those are pretty representative groups. The former group will bleed you dry, and the latter group is only good if the property is in good shape when you take it on and keep it that way.
Your standards need to drive the property management company. Your values need to drive process and procedure. Your competence will ultimately drive your reputation.
As a new PM, you will take any door you can get. It takes a long time to build a portfolio and a reputation to the point where you can call the shots.
