Opportunity Zone Loophole?

[Dave Peterson]

Forgive my ignorance here. I'm just getting started in investing, so this topic may be old hat for a lot of you.

I'm wondering if I were to do a 1031 exchange to a property in an opportunity zone, would I never have to pay capital gains tax on either property (if I sold the second property)?  Happy to clarify my thinking if this doesn't make sense.

Also, if anyone knows any advantages/disadvantages of refinancing a home in an opportunity zone, I would love to hear those!
