I'm not European but I lived in Denmark for 9 months for study abroad and London working in an architecture office for 6 months.

The architecture.

There are fundamental architectural differences between human brains and computers.Computers are not intelligent.

@Jonathan Orr my family owns an architecture firm in LA called Ryder Design and Architecture.

I can represent occupying 51% of the space and can represent it on paper - I'm familiar with BOMA because of my business (architecture). 

Certain pockets are turning over very quickly (Homes selling $300+), but 3 blocks away the same house sits on the market at $150.I am personally looking to do my own investing and development in Germantown (my background is architecture), so I believe in the neighborhood, but you have to be careful.

I actually work at an architectural firm that specializes in apartment buildings and I can tell you its not cheap.

I do want to look into the water sensor -- that's a good idea.Your specs above are a great way to start with a holistic architecture.
