Maybe try something along the lines of "that's unbelievable, how ever did you do it!?"

This is an unbelievably annoying practice. 

I'm happy to share my experiences with any out of state investors (especially from California as some of the prices in the south are probably unbelievable). 

Here are the main ones:1) I’m not happy, My major in architecture requires an unbelievable amount of time and effort, I’m doing extremely well but I’d rather be investing this time into something I enjoy learning (real estate). 2) If I stay this track, I’ll be 120+ thousand dollars in debt for a degree in architecture when I do not need this degree to be in real estate.

It’s unbelievable because home prices have increased and deals are happening.

It's like in the US in 2008, you could get unbelievable deals because most people were frightened.

that is unbelievable.  

Born and raised there, the amount of population and job growth in the last 5-10 years is unbelievable.

I heard a few unbelievable stories, all before the statutory changes.

In the midst of this unbelievably protracted divorce I obtained my residential contractors license and will be looking to use the remaining amount of my equity from our marital estate to build some spec homes in the future.Thanks!
