Portland boot calculation support for 1031 exchanges, running cash and debt-replacement math before closing statements lock in taxable exposure.
Boot is whatever value leaves the exchange as cash, debt relief, or non-like-kind property, and it is taxable to the extent of realized gain even when the rest of the exchange succeeds. The math is arithmetic, not opinion: relinquished value and debt payoff on one side, replacement price and new debt on the other, with the gap between them showing up as boot if it isn't closed before the settlement statement is signed.
Sell a $3.5M Columbia Corridor industrial building carrying a $1.4M loan payoff, leaving $2.1M in equity. Replace it with a $3.1M Hillsboro flex building financed with a $1.0M loan and $2.1M in cash equity. The replacement debt is $400K lower than the relinquished debt, and unless that gap is covered with additional cash contributed at closing, it shows up as mortgage boot. Separately, any cash actually distributed to the investor rather than reinvested, sometimes as small as a prorated security deposit refund or an over-funded reserve released at closing, counts as cash boot regardless of the debt math.
Closing credits are the most common place boot hides. A seller credit for deferred maintenance, a prorated tax adjustment that nets in the investor's favor, or a security deposit transfer that exceeds the replacement property's own deposit liability can all create small cash boot amounts that are easy to miss line by line but add up when the CPA reconciles the full exchange. Reviewing a draft statement before it is finalized, rather than after, is the only point where these items can still be restructured.
The $400K debt shortfall in the example above doesn't have to become boot; it can be closed three ways: contribute an additional $400K in cash toward the replacement purchase, negotiate a larger replacement loan if the property and lender support it, or add a second replacement property, such as a $450K DST allocation, to absorb the gap under the identification rule already governing the exchange. Each option has a different cost: added cash reduces liquidity, a larger loan increases debt service, and a second property adds another closing to manage inside the same 180-day window. Running all three scenarios before the purchase contract is signed, rather than discovering the shortfall on the settlement statement, is what keeps the choice a planning decision instead of a last-minute scramble.
A DST allocation used to close a debt gap needs its own boot check, since the debt embedded in a DST offering is often non-recourse and structured at the trust level, meaning an investor's share of that debt may not track dollar-for-dollar to what was needed to replace relinquished debt.
The federal boot calculation is identical whether the replacement property sits in Multnomah County or across the river in Clark County, Washington; state lines do not change the debt-and-cash arithmetic. What does change is the tax treatment of the eventual disposition, since Oregon and Washington tax gain differently, which is a separate question from whether boot exists at the time of the exchange itself and should be raised with the tax advisor independently. Some investors weigh that difference when deciding whether to place a larger share of replacement value in Clark County rather than Multnomah or Washington County, treating the boot calculation and the long-term hold decision as two separate conversations rather than one.
Any cash received, debt relief not offset by new debt or added cash, or non-like-kind property received as part of the exchange. It is taxed to the extent of realized gain, even if the rest of the exchange qualifies for deferral.
Not exactly, but any shortfall in replacement debt generally has to be offset with additional cash invested, or it becomes mortgage boot. Replacing more debt than was paid off does not create boot on its own.
Yes, if the deposit received on the relinquished property sale exceeds the liability assumed on the replacement property, the difference can be treated as cash boot. It is a small line item that is easy to miss on a settlement statement.
No, the federal boot math is the same regardless of which state the replacement property sits in. State income tax treatment of the eventual gain is a separate question worth raising with your tax advisor.
Your CPA makes the final determination on Form 8824, but organizing accurate settlement statements, debt figures, and closing credits ahead of time is what makes that calculation reliable rather than reconstructed months later.
