Oh, good question. Nope, I cannot say that there are many - only 2 or 3 most interesting ones. But to be honest, the most advanced solution (and my latest discovery at the same time) is Housinet ICO. What I am really impressed with here - entirely new and innovative approach on real estate and property management industry. Deep analysis, downtimes evaluation, metrics, p2p rentals and much more via 1 single ecosystem. And yeah, great partnerships with leaders on industry make sense as well. So I definitely recommend you to have a closer look at what the guys are offering, just Google them, platform is in very high demand these days
