Is It Better To Specialize In Commercial Property Management Rather Than Residential?

If you’re a property manager, you’re going to get paid based on a percentage of the net income of the property.
Depending on if you are doing this YOURSELF, or if you have a team, commercial (apartments) is more profitable because the cashflow is higher. You are also more likely to be working with more savvy investors who will know how they want their property run. Dealing with single family’s may be less work for you, but less profitable unless you have a bunch of them, and then you can get into trouble if all the properties need something urgent at once.
Why get into management working to put dollars into someone elses pockets when you can own and put all the money into YOUR pocket?
Best of luck in whatever you decide to undertake. WHATEVER YOU DO, learn more before you advertise that you are a property manager. People will be expecting you to run background checks on possible tennants, etc, you need to really know your stuff. You aren’t ready yet.

Try both residential as well as commercial properties.
