Real Estate Tax Calc
The strategy in plain terms
"Swap till you drop" means doing a 1031 exchange every time you sell investment property, rolling 100% of your equity forward. No capital gains or depreciation recapture is paid along the way — all the compounding happens without a tax leak. You hold the final property until death.
The step-up at death
Under IRC Section 1014, heirs inherit property at its fair market value on the date of death — not the decedent's lower adjusted basis. All the accumulated deferred gains and recapture are reset to zero. Heirs can sell immediately at minimal tax, or restart depreciation from the higher stepped-up basis.
Important caveats
Estate tax may apply to large estates (thresholds are subject to legislative change). The step-up only helps for property held in the estate at death — it doesn't apply if you sell without another exchange. Always model the full picture with both an estate attorney and a CPA.
A dollars-and-cents illustration
Imagine you build a $2,000,000 portfolio through decades of exchanges, with an adjusted basis of just $400,000 — meaning $1,600,000 of built-in gain, including several hundred thousand of accumulated depreciation recapture. If you sold outright, you might owe roughly 20% federal capital gains on much of the gain, up to 25% on the unrecaptured Section 1250 portion, the 3.8% net investment income tax, and state tax on top — easily a $400,000+ combined bill. Hold that same portfolio until death and your heirs' basis steps up to the $2,000,000 fair market value. They can sell the next day for close to $2,000,000 and recognize almost no taxable gain. The deferred tax you carried for decades simply evaporates.
Why the step-up is so powerful with recapture
A 1031 alone only defers depreciation recapture — it stays embedded in your low carryover basis and normally comes due on a final taxable sale. The step-up at death is what actually erases it. Because basis resets to fair market value, the accumulated depreciation that would have been recaptured at up to 25% (Section 1250) or ordinary rates (Section 1245 cost-seg components) is wiped clean. This is why cost segregation and swap-till-you-drop pair so well for long-term holders: you take accelerated depreciation now, defer the recapture through exchanges, and let death eliminate it.
Community property and the double step-up
In the nine community property states (plus Alaska by election), a special rule can double the benefit for married couples: when one spouse dies, both halves of community property get a stepped-up basis, not just the deceased spouse's half. In common-law states, only the decedent's share (typically 50% of jointly held property) steps up. Titling and state law therefore materially affect how much gain the survivor can shelter, so couples with large real estate holdings should coordinate ownership form with their estate attorney well before either spouse's death.
The estate-tax trade-off
Swapping till you drop keeps assets in your estate, which is exactly what triggers the income-tax step-up — but also what exposes large estates to the federal estate tax (and state estate or inheritance taxes in some jurisdictions). For most families the federal exemption is high enough that estate tax is a non-issue, but ultra-high-net-worth investors face a genuine tension: strategies that pull property out of the estate to dodge estate tax (gifts, certain trusts) generally forfeit the step-up, re-exposing all that deferred income tax. The right answer depends on estate size, the exemption in effect, and state law — this is squarely a job for an estate-planning attorney and CPA together.
Practical execution and recordkeeping
To make the strategy work, treat documentation as a decades-long project. Keep, for every property in the chain: the original purchase price and closing statement, all capital improvements, the full depreciation schedule, and the settlement statements and intermediary paperwork for each exchange. Your executor and heirs will need a clean record of adjusted basis and the date-of-death fair market value (usually an appraisal) to claim the step-up correctly. Consider holding property in a revocable living trust or an entity whose basis mechanics you understand, and revisit the plan whenever tax legislation — especially any proposal to limit the step-up or the §1031 rules — is on the table.
Cash flow while you hold: refinancing tax-free
A common objection is that swap-till-you-drop locks up your money — you never sell, so how do you access equity? The answer for many investors is a cash-out refinance. Borrowing against appreciated property is not a taxable event, so you can pull cash out to live on or reinvest without triggering the deferred gain or recapture. The loan proceeds aren't income, and the interest may be deductible against the rental. This is the quiet engine behind "buy, borrow, die": exchange to defer, borrow to access equity tax-free, and hold until the step-up erases the gain. The caveat is real leverage risk — a downturn or vacancy can strain a heavily mortgaged portfolio, so borrow conservatively.
Entity and title structure matters
How you hold title shapes both the exchange mechanics and the step-up. Property held individually or in a single-member LLC (disregarded for tax) exchanges and steps up cleanly. Partnership interests are trickier — you can't 1031 a partnership interest itself, which is why "drop and swap" structures convert partners to tenants-in-common before an exchange. At death, an interest in a partnership gets an outside-basis step-up, but the inside basis only adjusts if the partnership makes a Section 754 election — without it, heirs may not get the full benefit on the underlying real estate. Coordinate entity choice with your CPA early; restructuring right before death or a sale is far harder.
A lifecycle timeline
Picture the strategy across a career. In your 30s–40s you acquire and trade up, using 1031 exchanges to roll gains into larger properties and cost segregation to accelerate deductions. In your 50s–60s you might exchange into lower-management assets — a Delaware Statutory Trust (DST) interest or triple-net-leased property — to keep deferring while reducing hands-on work; DSTs can qualify as replacement property in a 1031. In your 70s+ you stop exchanging and simply hold, drawing income and borrowing against equity as needed, so the portfolio is in your estate at death. Heirs then receive the step-up. Each phase serves the same end: never trigger the taxable event during life.
Risks and reasons it can fail
The strategy is powerful but not guaranteed. Legislative risk is the biggest: proposals periodically surface to cap or repeal the §1031 exclusion or to limit the step-up in basis, and either change would blunt the plan. Estate tax can claim a large slice of very big estates even as income tax is avoided. Liquidity and leverage risk bites if you must sell in a bad market or can't service debt. And a single botched exchange — a missed deadline, touched proceeds, or a disqualified property — can trigger decades of deferred gain at once. Because the payoff depends on events (your death, future law) you don't fully control, treat swap-till-you-drop as a strong default plan that you revisit regularly, not a set-and-forget guarantee.
Getting the team right
This is not a do-it-yourself strategy at the finish line. You'll want a qualified intermediary for every exchange, a CPA who tracks basis and recapture across the whole chain, and an estate-planning attorney to align titling, trusts, and the step-up with your family goals and your state's law (community property versus common-law rules materially change the outcome). Review the plan after any major tax legislation, any large refinance, and any change in family circumstances. The cost of good advisors is trivial next to the six- or seven-figure deferred-tax liability the plan is designed to ultimately erase.
What heirs actually inherit
It helps to see the endpoint from the heirs' side. They receive the property at its date-of-death fair market value, which becomes their new basis. If they sell immediately, there's little or no gain because the sale price roughly equals the stepped-up basis. If they keep it as a rental, they get to restart depreciation from that higher basis over a fresh 27.5- or 39-year life — a brand-new stream of deductions on property that had been fully or heavily depreciated in your hands. Either way, the accumulated deferred gain and recapture you carried for decades simply never gets taxed. Make sure your heirs know an appraisal at death is essential; without documented date-of-death value, they can't substantiate the step-up they're entitled to.
Frequently asked questions
Does 'swap till you drop' eliminate capital gains taxes?
For heirs, potentially yes — the step-up in basis at death can erase the accumulated deferred gains and recapture entirely.
What if Congress changes the step-up in basis?
It's legislative risk. Review your estate plan whenever major tax legislation is proposed or passed.
Can I access my equity without selling and paying tax?
Yes — a cash-out refinance lets you borrow against appreciated property tax-free, since loan proceeds aren't income. This is the 'borrow' step in buy-borrow-die, though it adds leverage risk, so borrow conservatively.
Does the step-up also eliminate depreciation recapture?
Yes — because basis resets to fair market value at death, the accumulated depreciation that would have been recaptured (up to 25% on real property) is wiped out for property held in the estate.
Do community property states offer a bigger step-up?
Yes. In community property states both spouses' halves step up when the first spouse dies, versus only the decedent's share in common-law states — a meaningful advantage for married real estate investors.
Doesn't keeping property in my estate risk estate tax?
It can, for very large estates. The same estate inclusion that grants the income-tax step-up is what exposes assets to estate tax, so high-net-worth investors must balance the two with professional guidance.
