i feel like i live in a different world after reading this topic. suffice it to say that it is not a developed country and the inflation rate is high!
Who is going to live in your apartment when everyone around you starts to own a spare one? There's not enough people coming to towns to satisfy the market.
not everyone is going to buy real estate and there will always be people who want to buy it so there is always demand and there will always be others who want to rent.
it also depends on where the real estate is. for instance in big cities and capitals there is always going to be a demand and increase of real estate prices.
there is also the case of Up and Coming Neighborhoods. it is an investment after all and you always want to invest in something that has a potential of rise or is already rising instead of buying something that might rise or not! it is like buying altcoins, you don't want to buy some altcoins that is already big and pumped. you buy an altcoin that has not yet been pumped and is starting to get hyped up.
new ones are cheaper than the old ones. Why?
i have seen cases of houses that were old but more expensive but that was because of the location of them and the demand for that location but generally speaking the new ones, specially the brand new ones that nobody has been in yet is always higher.
