It is known that real estate follows inflation and as such it is a good investment, however at the same time we must remember that this is not a linear process and there are times in which real estate is overvalued and others in which it is undervalued, and at least to me real estate seems to be once again overvalued at a lot of countries around the world, and as such I still think that the best investment that someone can make these days is to put their money in bitcoin.
That's the biggest trouble plus we are talking about a big investment for most people, and even though almost all houses have owners, it is not easy to sell a house neither. It takes time, if you want to sell bitcoin then you open up your exchange and sell it, that's it, maximum of 10 minutes, I am so used to it by now that I can do it under 1 minute.
But when you want to sell a house, first you put it on the market, then a realtor contacts you, then you gave the realtor right to sell it, then they find you a buyer in god knows how long time, then you end up with something more and more and more on paperwork, and then you sell it and get the money. As you can see, this may take as much as many months before you can do that, my parents sold their house in 17 months for example, that's the issue.
