The provision to treat Mortgage Insurance as Mortgage Interest expires for 2022.

While there is a good chance Congress will do their traditional retroactive renewal, let's say it is NOT renewed.

Is it still a deduction on 8829 for a Home Office for 2022?  It wouldn't be listed as mortgage interest, but to me it still seems like a business expense (perhaps an "other" deduction on the 8829).

The 2022 Draft instructions for 8829 just say it has expired, but nothing else about it.

Any thoughts? 

P.S.:  I normally wouldn't care until January, but I specifically need to figure this out in the next couple of days.
