A signed P & S for new house of equal exc value that will not be complete until 2024

[Sarah Minor]

Question. So we have identified and signed a P and S for a new property to be constructed  by July 1, 2024 with a drop dead completion date of Nov 1,2024.  I spoke with the realtor selling my relinquished property yesterday and he feels that we can meet the 6 month deadline with ease, when putting our house in a very desirable area on the Market in the Spring. In theory, it could be listed on March 1 with a closing date of April 30 and even if we had to wait until an Oct closing for newly constructed property we would meet the 6 month requirement for exchange.  He also said that it is possible to get an extension for the 1031 in this case, which is not what my QI had indicated.  Does anybody have experience with this kind of situation?  Thanks in advance.
