In many states, there's a homestead exemption on property taxes that doesn't apply to non-owner occupied properties, so the opposite is true.
Also, I don't know what you mean about rolling paper losses into the next deal, but I suspect it's not accurate either.
There's a reason this non-existent loophole wasn't mentioned in the article that was looking for reasons to hate on corporate landlords.
Capital loss carryover is possibly what they were referring to
Unrelated note but the Homestead exemption in Santa Clara County, average sale price $2,300,000, is $7,000. To be explicit, the home’s value is reduced by $7,000 for valuation purposes.
Edit: the tax deferred part sounds like a 1031 exchange
