What happens to RE during deflation?

[Hersh M.]

I am new to RE and currently getting ready to jump in after studying through lots of podcasts, articles, books, etc. But (always a but, right?) I recently came across this 2010 video from Robert Kiyosaki - https://www.youtube.com/watch?v=HptRcmUGRAk

Considering that FED is not ready to raise rates and central banks around the world are reducing rates and/or pumping money into the system including China and India. And considering that US official inflation numbers are sitting on the fence between inflation and deflation even after so many years of easy FED policy, the hyper scenario mentioned in above video seems like a real possibility to me. 

But I have no prior experience in RE or in deflationary environment. I have heard here that as long as the property cash flows, just get in. 

So does anyone here have prior experience in deflationary environments and how does it impact your RE portfolio? Would you mind sharing your wisdom?

Please let me know if my question is not clear. 

Thanks.
