Has any investor done a 1031 exchange on a 2 family and whom did you use as a qualified intermediary?

When completed, I would turn over to the 1031 intermediary $1,25 mil (= total paid to me by the purchaser less $500,000 spent on the construction of the house), and purchase a replacement rental property for $1.25 mil or more.

It’s important to note that there are rules about switching between investment types so it’s critically important to work with your tax professional to make sure you’re moving into the right investment typeIntermediary – You’ll need to engage a 3rd-party intermediary to manage the funds as they move from the sold investment to the new investment.

The 180th day is not extended.Some other 1031 exchange intermediaries hold the same opinion:Equity Advantage  https://www.1031exchange.com/i...Greenberg Glusker https://www.greenbergglusker.c...However, some other companies are saying the oppositeFirst American Exchange Company https://www.firstexchange.com/...Asset Preservation, Inc. https://apiexchange.com/disast...Affected Taxpayers: An “Affected Taxpayer” includes individuals who live, and businesses whose principal place of business is located in, the Covered Disaster Area.

That is the qualified intermediary function.5.  

Documents are prepared as part of a normal closing by the qualified intermediary and the exchange is recognized on the settlement statement.  

I am reading a book about 1031 exchanges however there is no mention of intermediaries.

@Chuck Cirulli: Investing in exchange traded markets have a lot of exemptions built in for the IRA investor and it is primarily around the fact that you are working through an intermediary (i.e. an exchange) where the buyers and sellers are generally anonymous.

It's only a matter of time before blockchain technology penetrates the real estate market.The days of intermediaries in this space are limited in my opinion. 

I know people who broker or otherwise act as intermediaries.
