This is quite a marginal domain, that has very little application or use. The best idea for development, that I can think of, is to use the name as a site that advises people on money making ideas and methods that can be operated/enacted from a very small space, e.g. a "studio".
If, of course, "studio income" is a phrase that has some other meaning, perhaps in the area of taxes, then that will likely be the highest-use dev. idea for the name instead.
As for value, I don't see why someone wouldn't pay up to $250 or so for the domain, if they had a development idea in mind...
