Here is an article written TODAY on the subject of when a natural disaster etc can trigger 1031 extensions. IRS has to make it official, though. 

"Under Rev. Proc. 2018-58, the IRS laid out the requirements that would allow participants in a Sect.  1031 exchange to have an extension of these two key deadlines. However, in order for Revenue Procedure 2018-58 to come into effect for a specific disaster, the IRS must issue a notice or other guidance specifically authorizing Rev. Proc 2018-58 to go into effect and identifying those taxpayers eligible for its benefits. 

Unfortunately, despite all the recent legislation that has come out, the IRS has not yet issued such a notice or guidance. As a result, on March 23 of this year, a coalition of trade associations representing the real estate industry and real estate investors, operators, owners and lenders sent a joint letter to Treasury Secretary Steven Mnuchin and other key policy makers, requesting that the IRS quickly issue such guidance."

I have not heard it being talked about, yet. Interesting comment from Candice A. Donofrio 

That is not in the Cares Act, but then they seem to have forgetten logisitics as well. My assumption is the answer is no. The IRS will be happy to collect the taxes

No but @kenneth jones is to go to guy. Or Candice below.

Yes, I've heard they were being petitioned in CA. That was an issue that started popping up on my radar about 10 days ago. 

Peter,

Candice A. Donofrio has the answer!  A

This is one of those subjects where when you need to know about it you will and when it passes so does the knowledge if not repeated...

I have not. I am with Caroline Gerardo on this. 

I have not heard of them being postponed.  I was right in the middle of a 1031 transaction when this all broke out and I was worried about the time lines.  Luckily, we close next week.  The next challenge, finding a renter!

I have not. We can still sell homes here so some investors are buying sight unseen as are home buyers.

Not at this time.

No, I get newsletters about them regularly and haven't seen anything about a change yet.

Nope. 

Great question, parked and reading.
