creative 1031 with builder?

[Bryan H.]

I want to 1031 out of an underperforming condo in DC, into a new construction single family home. The 180 day construction limitation is too short for a complete build. The basic theoretical idea is to make a contract/deal with the builder so I would be buying the property from him upon completion. It would work something like this: I would delay sale of my condo until a couple months prior to timing of the new build completion date, so as to accommodate 1031 time requirements. Is this possible?
