@Benjamin Riehle I just upgraded my BP account to Pro level and added the audio/digital book package.

If you are ok with c and d areas there is potential of double digit returns.

Everything else for the most part is just agreed upon digital numbers on a computer program that can be changed , robbed or hacked .

In game theory there is the concept of a zero sum game in which you can only win if someone else loses, for example poker.

Vegas has been double digits also. 

However it's unlikely we will have double digits appreciation either, as we have seen in the past few years here.I actually thought about crashing and even the urge to sell before crash, then I realize I'll have to pay 8% in transaction cost and capital gains, market will have to crash at least 10% AND I'll have to time the market right to make it worthwhile.

Millennials, for the most part, grew up entirely in the digital age, and because of that, they have different expectations of the home purchase process than their parents and grandparents did.

Life isn't a chess match, it is a poker game. 

Also I think it is more like 2-3 hours job to dig it.

A few newer projects in my market utilize Digital Package Acceptance and promote it as an amenity. http://rvaterraces.com/amenities/I'm getting more detail from the developer and will let you know what I find.
