Hey Vashist getting into property management is a great job providing steady income. It also can be stressful as there are a lot of things you need to do/handle on behalf of the owner, tenant and property. It is not a 9-5 job and there will be nights and weekends involved, pending tenant issues and maintenance emergencies. Things to keep in mind, if you have no experience you usually will start off in an assistant role to learn the job and how your employer does things. Once you have proven yourself you can advance to different types of roles to include Leasing Agent, Property Manager, Business Development, etc. In most states you are required to be a Realtor in order to do Property Management so I would check with your local laws. By taking that training you will have better insight as to the role of a property manager. But in my opinion, that is not enough. You should look into the organization National Association of Residential Property Management. They have a ton of training and conferences that will help you better understand the industry.
If you only plan for this to be your side hustle, I would highly recommend finding a different side hustle. You will be in charge of the publics most valuable asset and if you can't give it your full attention, it may be best leave that job to someone else.
Best of luck!
