Estate tax planning for real estate usually starts with a question that has nothing to do with the federal estate tax itself: what happens to the capital gains you have been deferring or accumulating if you never sell? The answer is one of the more owner-friendly parts of the tax code. When you die owning appreciated property, your heirs generally receive it at a stepped-up basis equal to its fair market value on the date of death, which means decades of appreciation, and any gain you had deferred through prior sales, can pass to the next generation without anyone paying capital gains tax on it.
That single mechanism reshapes how a lot of Miami property owners think about selling versus holding into their later years, because a sale during life locks in a tax bill that holding until death can erase for whoever inherits.
The Federal Estate Tax Is a Separate, Narrower Issue
The federal estate tax applies only above a large exemption threshold, adjusted annually and set well into the tens of millions per individual under current law, so most property owners will never owe it directly even on a substantial Miami portfolio. Where it does bite is on larger estates, and Florida has no separate state estate tax, which makes Florida a comparatively favorable place to hold real estate for this purpose relative to states that layer their own estate or inheritance tax on top of the federal rules. None of this is legal or tax advice specific to your estate, and the exemption amount and rules are set by Congress and subject to change, so this needs review with an estate attorney rather than assumed from a general article.
Why "Swap Until You Drop" Became a Real Strategy
Because a 1031 exchange defers gain rather than eliminating it, and because death erases deferred gain through the step-up in basis, a long line of investors have built a strategy around the two rules working together: keep exchanging into new investment property throughout life rather than selling and paying tax, and let the accumulated deferred gain disappear at death for the benefit of your heirs. It is often shorthanded as swap until you drop, and it is one legitimate application of the exchange rules, not a loophole, though it only works if you are comfortable staying invested in real estate rather than eventually cashing out during your lifetime.
Where a DST Fits for an Aging Owner
Active property management gets harder for a lot of owners as they get older, and a Delaware Statutory Trust reached through a 1031 exchange offers a way to keep the deferral and the eventual step-up benefit while stepping away from tenants, maintenance, and leasing decisions. It converts a hands-on rental into a passive fractional interest in institutional-grade real estate, subject to the same holding requirements and the private-placement, accredited-investor nature of that structure, with liquidity that is meaningfully more limited than owning property outright.
Coordinating With the Rest of the Estate Plan
Real estate rarely sits in isolation from the rest of an estate plan, and how title is held, whether inside a trust, jointly, or individually, changes both the estate tax exposure and how cleanly the step-up in basis applies. An estate attorney working alongside a CPA and the team coordinating any exchange should review the specific ownership structure well before a sale or exchange is contemplated, not scrambled together against a closing deadline.
Common 1031 Exchange Questions
Do my heirs owe capital gains tax on real estate I leave them?
Generally not on the appreciation that occurred during your lifetime, because inherited property typically receives a stepped-up basis to fair market value at death, which can eliminate the deferred gain built up through prior 1031 exchanges.
Does Florida have a separate state estate tax?
No. Florida has no state estate or inheritance tax, so property owners here deal only with the federal estate tax, which applies above a large exemption most estates never reach.
What does swap until you drop mean?
It refers to continuing to use 1031 exchanges to defer capital gains throughout your life rather than selling and paying the tax, with the goal of letting the deferred gain disappear through the step-up in basis at death.
Is a DST a good fit for an owner who wants to stop managing property but keep the tax deferral?
It can be, since a DST converts active rental ownership into a passive fractional interest while preserving 1031 deferral, though it comes with private-placement terms, accredited-investor requirements, and more limited liquidity than owning property directly.
Should I talk to an estate attorney before doing another 1031 exchange?
If estate planning is part of your goal, yes. How title is held and how the property fits into a broader trust or estate structure affects both estate tax exposure and how the step-up in basis applies to your heirs.
