Certainly, there are a lot of factors to be considered and not just one, when choosing between buying or renting an apartment. Firstly, the factor that he should consider is his budget. This is the amount that he is willing to pay. He must also consider the price range and check if he can commit to the payment. Next is the time of how long he is planning to live in the city. Thinking about this, if he plans to live for only a couple of months, then buying won't be a great idea. He must check if which decision would cater his comfort for the time he is staying. And lastly, the financial stability of the housing market. This is also a very important factor to be considered as well.
