Should I sell bundled properties at auction?

[Mark Wheeler]

I have 3 properties that I need to sell together.  Since a 1031 exchange is time sensitive I can't risk not selling all three together.  

My realtor has suggested selling at auction, all three on the same auction date.

She said I can set a minimum price which will not be posted on the auction site.

Any thoughts from someone who has gone this route to sell their properties?
