Interest Tracing and 1031

[Oleg Malkin]

Cashed out on a primary to buy an investment when the rates were good. If I sell the investment and 1031 into something else, I can just continue expensing that mortgage interest on the next investment?  Are there any nuances to interest tracing and 1031? As long as I do the 1031 properly (intermediary and all) and don't touch the sale proceeds, nothing changes from the interest tracing perspective? Or is 1031 not even required to keep tracing - like if I don't identify a replacement within 45 days? Seems like  a good way to save a low interest mortgage.

Thanks, Michael! As always, the most detailed and complete answer from "The Black Belt in Real Estate Taxation".

That's exactly how I imagined it worked.
