Hello, I am a real estate agent and I have been looking into real estate blockchain technology for a bit. I am interested in investing in several ICOs such as Atlant and Real. I still have a bunch of questions related to how a generic real estate crypto market would work. I dont understand it quite well yet

.
First is: would every building / property have its own token? And then who would decide how many tokens to be issued for a specific property?
I think the owner of the real estate property would have to initially set up the number of tokens and the exchange rate between building tokens and ethereum for example. Afterwards the price of tokens will freely fluctuate according to offer and demand like shares in the FIAT stock markets.
