Yes, you can combine real estate agency and housekeeping together. Starting a housekeeping company is actually not easy if you do it yourself. It involves waiter management (how to recruit, interview, and train) customer management (rapid promotion, pricing, contract signing, after-sales service, etc.), and store clerk management. Of course, there is also training on risk management and complaint management: there are handling plans for nannies stealing things, clients not paying wages, personal injuries, waiters, customers or staff skipping orders, as well as how to select a location, unify decoration, etc. Need training.
