You can't lauch real estate token yet. There is not legislation for this. every firm that will try to do this will have to be fully regulated. There is no way to eliminate middlemans. You own x% of real estate but there have to be someone who is renting it, fixing, maitaining etc.

For those wanting to own fraction of real estate there are REITS - ETFs from regulated funds investing in real estates all around the globe. There is no reason to invest now in this sector.
