Bear in mind that CoV has some really weaksauce / crappy view corridor legislations:

Since you mentioned the house is in East Van, I'm willing to bet that the view is not covered by any of the indicated protected view locations, meaning you could lose the view at any give moment with no recourse at all.
Properties with good views often see elevated prices. But if it isn't protected by any legislations at all, the property value is as good as being built on quick sand.
I went through a similar BS in Port Moody and found out how ridiculous these view corridor laws were -- Port Moody was worse because they have
NO view corridor legislations at all. I was very lucky that I got out of that property before the loss of view significantly reduced the property's value.
