Can you name examples where this oft-predicted result has actually happened (in the USA, anyway)? That certainly hasn't been the result in the Bay Area.
It definitely happened in Portland when they ran the Orange line. We were house-hunting a year or two before the new light rail opened, and realtors showing houses along its route were already starting to make a point of mentioning it.
As soon as it actually opened, neighborhoods that could use it suddenly got a lot more desirable (read: expensive).
Bethesda, Maryland. It was very sleepy before it became a metro stop. In the last 30 years it had a crap ton of development mostly centered around the metro.
Actually... Can you name a few places in a metro area that didn't experience such a boom after a transit stop was introduced? In the bay area even? I feel like I have only ever seen examples of it being good for retail, restaurants, home values.
Metro considers itself traditional fixed rail, not light rail.

I was responding to the specific claim "Light rail will create demand to live near and locate businesses near the stations." The point isn't about whether a broad area benefits from rail (vs. no rail at all) but whether adding light rail to a fully built-out environment will drive more dense business development near the added rail and because of the addition of rail. I don't know of any USA data that supports that.
Take a ride from the Seattle airport to downtown on the light rail sometime, then. You will see a lot of nice looking apartments that didn't used to be there. And you will see some less nice neighborhoods interspersed.
It's happening in advance of the Beltline transit in Atlanta. The Beltline has been building out park/trail and surrounding neighborhoods are doing very well. The light rail is currently just a promise.
