Can we use "just" for emphasis?

[moonlike]

Hi
I came across one exercise concerning different ways to make a sentence more emphatic.
The house was so/just expensive. The answer was "so". I don't disagree. However, I wonder if it's possible to have just here as well. I think I have heard it before (just before adjective). Can't we use it (just+adjective) to emphasize something?
P.S. Could you kindly tell me if we can't use it to emphasize, so what does it mean exactly? It's just expensive.

Thanks a million.

In "It's just expensive" it means "only". The house is not expensive and tasteful. It's not expensive and ugly. It's not expensive and bright green. It's just expensive. That's the only thing I want to/I can say about it.

If you really want to emphasise the fact that it's expensive, you could say "The house was just so expensive", with the emphasis on "so".
