Stay away from short sales because you must identify a property in 45 days and close in 6 months and some short sales take longer and may never happen at all. Foreclosures are not something you can deal with in a 1031 since it requires cash at the auction. Once most homes have gone through a foreclosure they are bought by the bank and then they are REO or bank owned homes and these are fine and can close pretty quickly.
I am wondering if you know all the details of a 1031 and the rules they require to be EXACTLY followed. If you took the proceeds of the sale at closing then you have already ruined the chance for a 1031.
