Tahoe2006, in addition to other considerations as stated above, if you have already closed your sale, you're too late.
You probably would have had to put that 1031 language into into your sales contract. At closing of your sale, proceeds from the sale would have had to have gone to a third party intermediary, to be held by them until you close on the replacement investment property you are purchasing.
And... the price of the replacement property you are purchasing would have to be equal to or greater than the one you sold.
There is also a short window to identify your replacement property, and then a longer one to purchase - but not that long.
At least that is my understanding/experience.
