Seems to be really tough to come up with any real data on this topic.I think you can derive some data from spending some time on VRBO.

Having said that, I have derived great benefits from being a member of my local REIA  which costs me next to nothing.

Hope you enjoy and derive a huge benefit from this wonderful platform.

Miami launches Miami coin, will pay interest / rewards in BTC, Kiyosaki says BTC has the greatest upside, Bitcoin of America listed as one of the fastest growing companies, Citi files to trade bitcoin futures - citing increasing demand, Europes largest derivatives platform will launch a Bitcoin futures fund.

About all you can do is show them how you derived the values you have, but this seller obviously isn't motivated (not suffering enough distress).

@Tom Conant As a late responder to you question a few days ago - In my opinion, a bitcoins value, in theory, is derived from the supply and demand of the finite number of coins, like you said, however there's more details that are pertinent here.

I have created a map of the Cleveland area that is derived solely from data (rather than anecdotes/opinions) to show risk level for each census tract and would be happy to show you... just inbox me if you're interested.

LU puts me in direct contact with other successful people and that is one of the primary benefits I've derived.  

All %'s are derived from total yearly income.

This is easier said than done because passive investors don't really hang out on free platforms because they prefer their privacy, don't derive any value from talking to new investors, and are busy living fulfilling lives ie family/job.2.
