Heirs selling an inherited Miami house or condo are often bracing for a tax bill that turns out to be much smaller than they expected, because inherited property gets a benefit most other real estate does not: the basis resets to fair market value as of the date of death, rather than carrying forward what the original owner paid decades earlier. That single rule is why an aunt's condo purchased in 1985 for $60,000 and worth $500,000 at her passing can often be sold soon after for close to that $500,000 figure with little or no taxable gain.
Selling inherited real estate taxes still apply, just on a much smaller number than most heirs assume, and the timing of the sale after inheritance matters more than people expect.
How Stepped-Up Basis Actually Works
Instead of using what the deceased originally paid for the property, your basis as the heir becomes the property's fair market value on the date of death, generally established through an appraisal or comparable sales analysis. Any appreciation that happened during the original owner's lifetime is effectively erased for tax purposes, which is why heirs so often owe little or nothing if they sell relatively soon after inheriting. Gain only starts accumulating from that reset date forward.
What Happens if You Hold the Property Before Selling
If the Miami real estate market moves before you get around to selling, whether that is six months or three years after inheriting, the appreciation between the date of death and the eventual sale date is taxable gain, calculated against the stepped-up basis rather than the original purchase price. Inherited property also automatically qualifies for long-term capital gains treatment regardless of how long you personally have owned it, which removes the holding-period question that applies to other property sales.
Multiple Heirs and Fractional Ownership
When a property passes to several siblings or heirs jointly, each one gets a proportional share of the stepped-up basis, and each heir's tax situation on their share is calculated independently, including whether they want to sell immediately, hold as a rental, or exchange their interest into another investment. Disagreements among heirs about whether to sell or hold are common, and structuring separate paths for each heir's share is often more workable than requiring unanimous agreement on one strategy.
If You Want to Keep the Property as an Investment
An heir who wants to hold the inherited property as a rental rather than sell it outright starts depreciation fresh from the stepped-up basis, and if they later decide to sell that rental, a 1031 exchange becomes available the same way it would for any other investment property, letting them defer gain accumulated after the inheritance date by rolling proceeds into a new property. The stepped-up basis and the exchange are two separate tools that work well together: one erases old appreciation, the other defers new appreciation going forward.
Getting the Appraisal Right Matters More Than Speed
Heirs eager to close out an estate sometimes skip a proper appraisal and lean on a rough estimate or a real estate agent's opinion instead, which can leave the stepped-up basis poorly documented if the IRS ever questions the reported gain later. A qualified appraisal dated as close to the date of death as practical is worth the cost, since it becomes the number every future capital gains calculation on that property depends on, whether the heir sells next month or holds for another decade before deciding what to do.
Common 1031 Exchange Questions
Do I owe capital gains tax on the full value of inherited property?
No. Your basis resets to the property's fair market value on the date of death, so tax generally applies only to appreciation that happens after you inherit it, not appreciation during the original owner's lifetime.
How is fair market value at death determined?
Typically through a professional appraisal or a comparable sales analysis as of the date of death, which becomes the documented basis for the heir going forward.
Does inherited property qualify for long-term capital gains rates automatically?
Yes. Inherited property is treated as long-term regardless of how long the heir personally has owned it before selling.
Can multiple heirs handle an inherited property differently?
Yes. Each heir's proportional share carries its own stepped-up basis, so one heir can sell while another holds or exchanges their share into a different investment.
Can I do a 1031 exchange on inherited property?
Yes, if you hold it for investment or business use rather than personal use, and the exchange would defer gain accumulated after the stepped-up basis date, not appreciation from before you inherited it.
