> For example 부동산(real estate), comes from the Japanese kanji word, 不動産, which in Chinese means 不(not)動(moving)産(assets). Does this inferential aspect of Chinese still apply in certain cases once it is written in Hangul?
It depends. For this particular example, I think most Koreans will treat 부동산 as a single word meaning "real estate", because it's not a very productive combination: the alternative 동산 (moveable properties?) is a legal term which is much less common, and 산(産) as "property" isn't common either.
On the other hand, a word like 고밀도화(高密度化 - densification) is transparently decomposable to 고(高 high) + 밀도(密度 density) + 화(化 -ify). Few people can write it down in hanja (I just copy-pasted from dictionary), but most people will immediately recognize its meaning, even if they've never seen the word before.
