Actually, the "short answer" would be "not yet".
As @Critter-3 stated, there are parameters for rental periods of vacation homes which, if met, would potentially meet the requirements for a 1031 exchange. Since @forestdan has not yet sold the property, it is not too late to comply with the requirements prior to a transfer pursuant to Section 1031.
Rev. Proc. 2008-16 provides a safe harbor for this purpose.
