Start 1031 exchange after sale of property is already in progress

[Steve Graves]

Selling a property I rehabbed a couple of years ago. I've accepted an offer and the process of the sale has started. Didn't think I was going to do a 1031 exchange because I was going to use the money for repairs on another property. Found a property I like though and want to do a 1031 exchange on it. Is it too late to start the 1031 paperwork?
