In my opinion, both can actually be profitable, when you sell it means you immediately get back the money you have spent on building the apartment building along with a number of benefits, while when you choose to rent it out to someone else there is an opportunity for You can get a bigger profit compared to selling it directly to someone else.
The difference here is only in terms of time, because of course the cost of building an apartment is not small, meaning that when you choose to rent out rather than sell it means you have to be patient to wait several years or maybe decades until all your capital money is returned, and after Only then will you get real profits from renting out the apartment when all your capital money has been returned, and also if you rent out the apartment for longer then of course your profits can also be bigger, in the sense that renting out is an idea for getting long-term profits compared to selling it. , but I understand that not everyone is really able to be patient for that long, and if the choice is which is better, selling or renting, of course it depends on your choice.
I think the most important thing to get profit is not whether you sell or rent your apartment or building but your location. If you build a house in a good location, you will rent it, then in a few years, you will get back the invested amount and you will also have your own house. You will also get your money back and after some time you will start making a profit, if your house is in a good location and is selling at a high price, you will get double your invested money. If you are getting it, you should sell it so that you can buy two properties instead of one.
When it comes to renting out a house, many other things need to be looked at, such as renters not taking care of the house in the same way that a landlord can, apart from when the house is renovated. There is a big difference between this and a ready-made house, the price drops, so even if you sell a ready-to-move house, you can get a good price for it, but once the house is used and you sell it, you don't get a good price for it.
So all these things have to be seen. Becoming a property dealer is not easy. You can become a successful dealer only if you know how to make the right decisions. You understand the value of your location. They should also be rented out rather than sold as their value doubles and triples over time.
