The 1031 Exchange, Explained for Florida Apartment Owners

The short answer

A 1031 exchange lets you sell an investment property and defer the federal tax on the gain by buying another one. You have 45 days to identify the replacement and 180 days to close, a qualified intermediary must hold the money, and taking cash out or reducing debt creates taxable boot.

The 1031 exchange is the most powerful tax tool an apartment owner has, and the most misunderstood. Owners either think it is a loophole for billionaires or they think it is simple. It is neither. Here is how it actually works, from a broker who has closed sales on both sides of one. As always: I am a broker, not a CPA or attorney, and you need both on a 1031.

What it is in one paragraph

Section 1031 of the federal tax code lets you sell an investment property, buy another investment property, and defer the tax on your gain, including depreciation recapture and capital gains. Not avoid. Defer. The tax bill follows you into the new property and comes due when you eventually sell for cash. Plenty of owners roll gains forward for decades this way, building from a fourplex to a hundred units without ever writing the IRS a check on a sale.

The two deadlines that kill exchanges

Everything in a 1031 hangs on two clocks, and both start the day you close the sale of your building.

Forty-five days is nothing in commercial real estate. The owners who succeed are shopping for the replacement before their building hits the market. The owners who fail start looking after closing, panic around day 30, and either buy something mediocre or blow the exchange and eat the full tax bill.

The intermediary rule

You cannot touch the sale money. Not for a day, not in escrow you control. A qualified intermediary must hold the proceeds between your sale and your purchase, or the exchange fails and the entire gain becomes taxable. Intermediaries are inexpensive relative to what they protect. Pick an established one, because you are trusting them to hold your money.

What counts as a replacement

Since the 2017 tax law, 1031 applies to real property only, but within real estate the definition of like-kind is generous. Sell an apartment building and buy another one, or a warehouse, or land, or, and I say this with a straight face because I run a brokerage for each, a mobile home park. Owners tired of apartment operations sometimes 1031 into parks for the simpler physical plant. The tax code does not care, as long as both are investment real estate.

Boot and debt: the two quiet traps

If you take any cash out of the exchange, that cash is taxable. It is called boot. And if your new property carries less debt than the old one, the difference is generally treated like cash you received, and taxed. The clean exchange buys equal or up, in both price and debt. Your CPA runs these numbers before you sign the purchase contract, not after.

When you should not do a 1031

The worst reason to buy a building is that the calendar told you to.

I have watched owners overpay for a mediocre replacement property in month five because the alternative was a tax bill. Sometimes paying the tax is the better deal, especially if your gain is modest or you want out of real estate entirely. A 1031 is a tool, not a religion. Decide with a calculator, not with fear.

If you are weighing a sale and want to know what your building would bring first, that number changes every other decision. Run it through the model below and you will have it in minutes.

And if you are on the other side of this trade, a 1031 buyer hunting a Florida replacement property with the clock already running, give me your criteria and I will bring the deals to you.

Questions owners ask

Can I do a 1031 exchange into a different type of property?

Yes, as long as both properties are investment real estate. Since the 2017 tax law, a 1031 applies to real property only, but like-kind is generous within real estate. You can sell an apartment building and buy another one, a warehouse, land, or a mobile home park. Some owners tired of apartment operations exchange into parks for the simpler physical plant.

What happens if I miss the 45-day identification deadline?

The exchange fails and you generally face the full tax bill. You must name your replacement property in writing to your intermediary within 45 days of closing your sale, and the 180-day closing deadline gets no extensions for a slow lender or a bad inspection either. The owners who make it start shopping for the replacement before their building ever hits the market.

Can I keep some cash from the sale and still do a 1031?

You can, but the cash you take out is taxable. That cash is called boot. Carrying less debt on the new property than on the old one is generally treated like cash received too, and taxed. The clean exchange buys equal or up in both price and debt, and your CPA should run those numbers before you sign the purchase contract.

Can I hold the sale money myself until I buy the replacement?

No. You cannot touch the sale proceeds for even a day, including in an escrow you control. A qualified intermediary must hold the money between your sale and your purchase, or the exchange fails and the entire gain becomes taxable. Intermediaries are inexpensive relative to what they protect, so pick an established one, because you are trusting them with your money.

Is a 1031 exchange always better than paying the tax?

No. Sometimes paying the tax is the better deal, especially when your gain is modest or you want out of real estate entirely. I have watched owners overpay for a mediocre replacement in month five just to avoid a tax bill. A 1031 defers the tax rather than erasing it, so decide with a calculator and your CPA, not with fear of the deadline.

If you are selling to start a 1031, I work as your Florida apartment broker on both sides of the clock: pricing the sale and matching you to replacement buildings before the 45 days run out.
