1031 only option?

[Jacob Campbell]

I had intended to sell about $5.3MM of rental property and simply use the profits to may off debt on other notes.  However, I'm told my tax basis will be close to $2MM after depreciation recapture.  

Does anyone have any ideas on how to minimize that tax liability and still continue with my original intent, or is my only option a 1031 (I'm aware of DST but don't see that as a great option).

If so - any thoughts on rolling the profits from residential multi family sale into a commercial office building?   Is office still underperforming or is now seen as a safe investment again?
