it its a fair bet that if China government  do nothing for real-estate market the bubble would sooner be tipped off .   bu doğru görünüyor mu?

I would write it like this:

It is a fair bet that if the Chinese government does nothing for the real estate market, the bubble will pop sooner.

I changed "China government" to "the Chinese government".

I think the idiom "Tip-off" or "Tipped off" is usually used when secret information is given to people who wouldn't normally have it. I haven't really heard it used in the way that you did. Maybe instead use "popped", as that is what bubbles do, or you could also use the word "collapse" which is often used in the context of markets.

I would also add at the end the phrase "than if they had done something", because usually "sooner" is a comparison. You would say X happened sooner than Y.

If you would like me to clarify something, feel free to ask!
