They allow multiple codes, allowing you to have a master code, while your tenants have their custom code (this is also clutch for STRs).

Think if pictures for example had blockchain security so that they couldn't be appropriated by rogue websites.....or that properties could be assigned code so that title search and transfer was more secure (and significantly less costly.)   

I also stay up late studying code and other DeFi investment strategies too.

and typically "well meaning" is code for "God bless his heart, he's trying to help but he's wrong" - what you mean to say is "my friend who's a professional in the industry and well respected on these forums, but I don't like his answer and I'm hoping like Hell he's wrong, so I'm going to keep asking the general public until I find the one person who says what I want them to say, in order to confirm my hopes

I like to target zip codes and people who plan on moving on Facebook.
