There are ways like a reverse 1031 that could help with this, but I would say in general that a 1031 makes the most sense when you get a great deal on the replacement property, and that is tough to do for me in my hot market, but your mileage may vary.Unless you are dead set against holding as a rental, I'd seriously consider cash out refinancing to fund your next deal or hold tight without cash out refinance until you have saved the capital for the next deal.Or if you are set against holding as a rental and you want to be a flipper, then just sell and pay the taxes and move onto the next one.
