Treasury Regulation §1.162-21

And you might be very surprised what the Treasury, Service, and tax courts have allowed as "unforeseen circumstances"...

The treasury yield curve inverting is one thing that does seem to back up the claims.

Rates are standard set by the market and treasury rate which than is factored with a person credit score, income, etc.

Actually fell a lot as I was locked in for my refinance due to all this Trump induced drama, treasury yields are getting slaughtered.  10 yr yield was about 2.50% when I did mine.

However, after watching 10 year treasury yield drop recently and with talk of a recession coming soon, I am hesitant about getting started right now.

@Aaron MoayedIf you dig far enough into IRC Sec 469 and the related regs, you'll find this:Treas Reg Sec §1.469-1(f)(4)Carryover of disallowed deductions and credits(i)In generalIn the case of an activity of a taxpayer with respect to which any deductions or credits are disallowed for a taxable year under § 1.469-1T(f)(2) or (f)(3) (the loss activity)—(A) The disallowed deductions or credits is allocated among the taxpayer's activities for the succeeding taxable year in a manner that reasonably reflects the extent to which each activity continues the loss activity; and(B) The disallowed deductions or credits allocated to an activity under paragraph (f)(4)(i)(A) of this section shall be treated as deductions or credits from the activity for the succeeding taxable year.When reading tax law, what is not mentioned is just as important as what is mentioned.This Treasury Reg section, taken together with the IRC Sec 469 helps establish there is no definite carryover period for passive activity losses -- as opposed to NOL carryover.
