Should I buy a property I don't want just to finish my 1031 exchange?

The arithmetic: a deferral is a one-time number, an overpayment is permanent

Hypothetical: you sell for $1,500,000 with a $500,000 gain of which $150,000 is depreciation. At the 2026 rates in Rev. Proc. 2025-32 and IRS Topic 559, joint filers under the $613,700 breakpoint would owe 25% of $150,000, 15% of $350,000 and 3.8% of $500,000: $37,500 + $52,500 + $19,000 = $109,000 federal, $126,500 above the breakpoint, and something near $150,000 in a state that taxes the gain, the figure used below.

Now overpay by 10% for a $1,500,000 replacement and $150,000 of equity is gone at closing, the same amount you deferred. The deferral was never a gift: Form 8824 line 25 carries the deferred gain into your new basis, so the $150,000 of tax is still owed on the next taxable sale (tax-free or deferred).

Yield does the same damage more slowly. A property earning two points less than the market on $1,500,000 gives up $30,000 a year, $150,000 over five years before compounding, and you still hold the weaker asset at the end.

The test a qualified intermediary uses: would you buy it with no deadline?

In a BiggerPockets thread on deadline-driven deals, the investor who opened it asked, 'Would you buy this property if there were no 1031 deadline?' A qualified intermediary replied that 'there is no penalty for not completing a 1031. Seasoned investors will keep the 1031 option available by starting it. But if the market doesn't look good, dont put anything on your identification list and let your exchange die on day 46.'

The thread's list of things not to compromise on is a usable checklist: cash flow proven by actual income rather than pro forma, debt terms and refinancing risk, tenant concentration, capital expenditure needs, and return assumptions that need optimistic projections. Fail two of those and the tax is the cheaper problem.

A placeholder that is not a compromise: a DST or direct-title interest named alongside the property you want

A Delaware Statutory Trust interest is institutional real estate that already exists, is already financed and closes on subscription documents; 1031 Crowdfunding lists $25,000 to $100,000 as typical minimums, exact-dollar investment amounts and closings 'in 3-5 business days'. Named on your list next to the building you want, it costs nothing to identify and rescues the exchange only if you need it (our DST backup guide).

It is a real investment with real trade-offs: no control, a sponsor hold of several years and no public market to sell into (DST key risks). It is also not a dead end; when the trust sells you can exchange again into a property you choose at leisure (parking money in a DST temporarily, what happens when a DST sells).

Breakwater Exchange places sellers into traditional DSTs and direct-title net-lease interests from vetted national sponsors, and can tell you within days which offerings are open at your dollar amount.

Three other exits that beat a forced purchase

Each of these keeps you from owning a building you would not have bought on an open calendar; which one fits depends on where your sale stands.

The partial route has a ceiling the dud lacks. With $1,200,000 to place and one $800,000 property you actually want, the $400,000 left with the QI is boot, and at 15% plus the 3.8% NIIT the federal tax on it is $75,200 at most in this hypothetical; a $400,000 slice of a building that loses value has no such cap.

• Reverse exchange, if your sale has not closed: buy the right property first through an exchange accommodation titleholder, then sell (reverse exchange guide, exchange types).
• Partial exchange: buy the one property that passes the no-deadline test even if it is smaller, and pay tax only on the unspent balance (one closes, another doesn't, trading down).
• Pay the tax and put the gain to work elsewhere: a qualified opportunity fund, which §1400Z-2(a) lets you fund with the gain inside 180 days, or a bonus-depreciation fund bought before December 31, whose first-year deduction is 100% of cost for qualified property bought after January 19, 2025 per Pub. 946 (Plan B guide, opportunity zone funds, bonus depreciation funds).

When letting the exchange die on day 46 is the right call

Leave the identification list empty and Reg. §1.1031(k)-1(g)(6)(ii) lets the QI release the funds once the 45 days pass, taxed in the year you receive them (when the QI releases funds). That is the right outcome when the gain is small next to the fees (minimum gain worth an exchange), when this is an unusually low-bracket year (paying tax in a low bracket), or when nothing on the market and no DST passes the test.

Do not name a doubtful property 'just in case': an identification you never use locks the money until day 180 unless its failure fits the written-contingency release. The list should hold only property you would be content to close on, which is exactly why a DST belongs on it and a dud does not.

Run the deferral figure and the overpayment figure side by side with your CPA or attorney before day 45; the comparison takes an hour and the wrong purchase lasts years.
