My mom wants to get into property management and the job descriptions all include "market research"? What kind of market research would you do for apartment buildings? She was a property manager for 3 buildings for 27 years and she never did or even heard of such a thing. What kind of background do you have to have?
Market research in this case means a basic knowledge of the housing market (rentals) in your area. It might include knowing strategies to improve a complex, or buildings profitability, or how to persuade the tenants to be more timely in their payments. It’s not any one skill set, but several.
In other words, the days of simply collecting rent are over. But if your mom is a quick study, she might be able to persuade them to give her a try, based on her previous experience.
Good luck to her!
