Yes there will be a premium for any type of view, the problem is trying to figure out what that premium is. Having been an appraiser I'll tell you how I would go about it.
The absolute best way is with matched paired analysis where you have a sold property with a view and the same basic sold property without one where the sales were at the same time. The difference in price would be the value of the view.
Since that hardly ever occurrs you need to find sales in a similar location and try to compare the views with non-views. There will be other differences in the properties that you will have to make adjustments for, also.
Something I used to do was go to all the sold property, in the area I was interested in, that had a view and ask the owners what they felt was the premium they paid for the view. If you get lucky and find enough of them you can get a pretty good idea.
Another thing to do is talk to someone in the property assessors office. If you can get the right person they can be a lot of help. You also might ask some of the local appraisers, again if you get lucky you'll get some good info.
If it is a fairly recently built property the builder premium amount might be of help.
I normally would start with what I thought the value was and try to prove or disprove my estimate.
There are other ways and this may help you think of them.
Good luck.
