Miami-Dade 1031 Exchange: Can You Find a Replacement in 45 Days?

Can you complete a 1031 exchange on a Miami-Dade rental in 45 days?

Yes, but only if you treat the replacement search as the first step, not the last. The 45-day identification clock starts the day your sale closes, and the 180-day closing clock runs at the same time, so you get 135 days after identification to close, not 180. With single-family inventory down about 19% from last year in Miami-Dade, the investors who succeed line up targets and a qualified intermediary before they list.

A 1031 exchange is the cleanest way to sell a Miami-Dade rental without writing a federal tax check. It's also the plan that quietly falls apart around day 38, when you've toured six properties, lost two to cash buyers, and realize the third one you liked needs a condo questionnaire you can't get back in time.

Here's how the deadlines really work, where Miami-Dade makes them harder, and how to decide whether an exchange is worth the pressure at all.

The clock, in plain numbers

Section 1031 still applies to real property held for investment or business use. Personal property exchanges ended in 2018, and as of the most recent sources I checked in mid-2026, nothing enacted has changed the real estate rules — the July 2025 tax bill left them intact. Congress has floated changes before, so confirm with your CPA before you list.

The deadlines are strict calendar days:

• Day 0: Your relinquished property closes. The proceeds go straight to a qualified intermediary. If the money touches your bank account, even briefly, the exchange fails.
• Day 45: You must identify your replacement property in writing to the intermediary. A weekend or holiday doesn't move it.
• Day 180: You must close on the replacement. If your tax return is due sooner than 180 days after the sale, the return due date (including extensions) becomes your deadline, so a fall closing can shorten the window unless you file an extension.

Your intermediary has to be independent. That generally rules out your attorney, your CPA, or anyone who's acted as your agent in the last two years.

There are three ways to identify property, and the choice matters:

• Three-property rule: Name up to three properties of any value. This is what most investors use.
• 200% rule: Name more than three, as long as their combined value doesn't exceed 200% of what you sold for.
• 95% rule: Name as many as you want, but you must buy at least 95% of the total value. It's rarely practical.

Why Miami-Dade makes day 45 harder

According to August 2026 market reports, Miami-Dade has about 4,330 active single-family listings, down roughly 19% from a year ago, with a median price near $680,000 and months of supply down about 23%. Condos and townhomes look different: roughly 11,265 active listings, a median near $420,000, and days on market up about 30%.

Read that as two separate markets. Houses are tight, so a good target can be gone before your inspection period ends. Condos have plenty of choice, but the questions that slow them down are building-level: assessments, reserves, and whether a lender will even finance the building.

If you're eyeing a condo replacement, use the same diligence you'd use for any purchase here. The seven-day document voidability window and the association's approval timeline both eat into your 180 days. An association that takes two weeks to approve you is a real cost in an exchange, not a minor delay.

Cap rates add another wrinkle. One June 2026 survey put luxury condo cap rates in Brickell, Edgewater, and Downtown at roughly 3.5% to 4.5%, with short-term-rental-friendly buildings showing 6% to 9% gross yields and 4% to 6% net. That means "like-kind" is easy to satisfy on paper and easy to get wrong on cash flow. A replacement that qualifies for the exchange can still be a worse investment than the property you sold.

What an exchange saves — and what it doesn't

Florida has no state income tax, so your exposure is federal. Here's a hypothetical for illustration only: you bought a Kendall townhome for $300,000, sell for $650,000, and your gain including depreciation you've claimed is about $400,000.

• Depreciation recapture (unrecaptured Section 1250 gain), say $60,000, is taxed at up to 25%: about $15,000.
• The remaining $340,000 is long-term capital gain at 15% or 20%: about $51,000 to $68,000.
• The 3.8% net investment income tax can add up to about $15,200 for higher earners.

That's roughly $81,000 to $98,000 in a high-income year, versus zero due at closing if the exchange works. The tax is deferred, not erased: your basis carries into the new property, and deferral works best when you have a long-term plan for it.

Two costs an exchange doesn't touch. First, documentary stamp tax on the deed still applies: in Miami-Dade it's $0.60 per $100 on a single-family home ($3,900 on $650,000) and $1.05 per $100 on a condo or other property ($4,410 on $420,000), and the seller customarily pays. Second, any cash you keep, or any reduction in your mortgage debt that you don't replace, is "boot" and gets taxed.

To defer everything, buy equal or up in price, reinvest all the equity, and replace the debt.

Four ways investors handle the 45-day squeeze

1. Search before you list. Line up target neighborhoods, price bands, and financing before the sale contract is signed. I walk my clients through this before we ever put a sign in the yard.

2. Widen the map. Like-kind is broad. You can exchange a Kendall rental for a fourplex, land, or commercial property, in Miami-Dade or in another state. Investors who limit themselves to a few zip codes are the ones who miss day 45.

3. Use a backup. Identify three properties with different risk profiles: one you'd love, one you'd accept, and one that's easy to close. Delaware Statutory Trust interests can qualify too, trading control for a defined closing path.

4. Consider a reverse exchange. You buy first and sell later through an exchange accommodation titleholder. The same 45 and 180-day clocks apply, and it costs more and requires financing the purchase before the sale, so it fits only when you already have cash or a lender lined up. My earlier post on whether to sell your Miami-Dade rental in 2026 covers the sell-or-hold math, and sell first or buy first covers the same timing tension for homeowners.

If the unit has had personal use, IRS Revenue Procedure 2008-16 offers a safe harbor for dwelling units: you generally need to have owned it at least 24 months, rented it at fair rent for 14 days or more in each 12-month period, and kept your personal use to the greater of 14 days or 10% of the days rented. Your CPA should confirm your facts fit.

When not to exchange

An exchange isn't a win if the replacement is worse than the property you sold. If your numbers show insurance, taxes, and HOA dues consuming the yield, paying the tax and redeploying cash may beat buying a weaker asset just to beat a deadline. Every situation is different, and the answer depends on your basis, your income, and your plans for the next ten years.

Frequently Asked Questions

How long do I have to complete a 1031 exchange on a Florida rental property?

You have 45 calendar days from closing to identify replacement property in writing and 180 calendar days to close, with both clocks starting at the same time. If your tax return is due sooner, that date can shorten the 180 days unless you file an extension.

Can I do a 1031 exchange on a Miami-Dade condo?

Yes, if the condo is held for investment or business use and the replacement also qualifies. Watch the association approval timeline, the seven-day voidability window, and whether a lender will finance the building, since each can consume days you don't have.

What is boot in a 1031 exchange?

Boot is any cash you take out or any debt reduction you don't replace. Boot is taxable in the year of the sale even when the rest of the gain is deferred.

Does Florida tax the gain from selling a rental?

Florida has no state income or capital gains tax. You'll owe federal tax on the gain, and the deed carries documentary stamp tax at $0.60 per $100 for a single-family home or $1.05 per $100 for a condo in Miami-Dade, which the seller customarily pays.
