developer company build a apartment to sell it immediately whatever profits they can make, but most of the time they did not take it for rent, renting is another business, who are not interested to short term business and they want to several times high profits they will go to rental business for long time.
Yes bro, it will be more profitable for the renter, but we have to have quite a large amount of capital to buy a reputable apartment, but when someone rents it continuously then little by little our capital will return as time goes by, their property company just build then they will sell all the property then they look for another place to build new property then they will sell everything too, because they adjust the main capital then they sell everything then they receive profits from a property project.
