Definition of 1031 "selection" for the mixed or oddball listings

[Michael Klinger]

Hello all,

I generally understand the 1031 rules and process.  I really not looking for a recap on the basic rules or concept. Got all that. Thanks.

However... In some Loopnet listing research I noticed that it's somewhat common to see  listing that is mixed. Such as a 32 unit plus a house in the same compound, or two adjacent complexes being sold as one. Or a portfolio hodgepodge of smaller buildings being offered as one package.

I also notice that some complexes that are seemingly one property with multiple buildings sometimes have several or separate parcel numbers for the purposes of property tax assessment and such.

Is there some guidance on what is "one" 1031 pick and what would count as more. I am assuming that a portfolio being sold as one is really as many properties as it lists in the portfolio. What about the other examples I gave?

Thanks,
