721 Exchange vs. Selling Outright: Taxes, Net Cash, and Tradeoffs

By Jerry Baker

Selling investment real estate can leave you with cash after paying costs, debt, and taxes; a qualifying 721 contribution can defer gain while giving you a partnership interest instead. The tax benefit can be meaningful, but it does not make the units equal to cash or remove future taxes and investment risks. A useful comparison starts with your actual gain, the net value you receive, and when you need access to it. [1]

Define the two transactions before comparing taxes

In an outright sale, a buyer purchases your property. You receive the agreed price, less the amounts paid through closing. Once you have allowed for taxes and other duties, the remaining cash can fund spending, new investments, or reserves.

In a common 721 arrangement, you contribute property to a REIT's operating partnership in exchange for OP units. Those units are partnership interests. They are not the same as owning the old building directly, holding cash, or buying REIT shares on a stock exchange.

Section 721 generally provides nonrecognition for a qualifying property contribution to a partnership. A sale does not become a contribution just because the buyer is linked to a REIT. Nor can you sell for cash and erase that gain later by buying shares. The substance and terms matter. [1]

My first question is what you want to receive. If you need cash to buy a home next month, a large unit balance may not solve the problem. If you want to stay invested in a suitable real estate portfolio for years, a contribution may deserve careful review.

Keep sale price, gain, and cash separate

These three numbers often get mixed together. Sale price is what the buyer pays. Taxable gain depends on the amount realized and your adjusted tax basis. Net cash is what remains after closing payments and taxes. They can be very different.

The federal rule generally measures gain as the amount realized less adjusted basis. A loan payoff does not turn your equity into your tax basis. Paying the lender affects cash. It does not usually reduce gain the way a qualifying selling cost does. [2] [3]

Adjusted basis also differs from the original purchase price. Improvements, depreciation, prior exchanges, and other events can change it. Ask your CPA for the current schedule rather than guessing from a loan statement or an old purchase agreement. [3]

A claim that “you have a $2 million gain, so you have $2 million to invest” skips the cash calculation. A highly leveraged owner can have a large tax gain and much less spending cash.

A worked example of an outright sale

This original hypothetical concerns a U.S. individual selling a long-held rental property. It is not a tax estimate for your return. Assume a $4 million sale price, $120,000 of selling costs that reduce the amount realized, $1 million of debt paid off, and $1.2 million of adjusted basis.

Separate gain from cash before estimating tax
CalculationResult
Price less selling costs$4,000,000 − $120,000 = $3,880,000
Amount realized less adjusted basis$3,880,000 − $1,200,000 = $2,680,000 gain
Price less costs and loan payoff$4,000,000 − $120,000 − $1,000,000 = $2,880,000 cash before tax

The gain is $2.68 million, but cash before tax is $2.88 million. The $1 million mortgage payoff appears in the cash calculation. It is not subtracted a second time from gain.

Now assume the tax adviser determines that $400,000 is unrecaptured Section 1250 gain, taxed at the maximum 25% rate in this example. Assume the remaining $2.28 million is taxed at 20%. We use these rates to keep the example simple. Not every seller pays them.

Finally, assume the full $2.68 million is subject to the 3.8% net investment income tax, with no offsetting deductions or losses. This assumes the income is high enough and all the gain is part of net investment income. This illustration excludes state and local taxes and other effects on the return.

Hypothetical federal tax under the stated assumptions
ComponentArithmeticTax
Unrecaptured Section 1250 gain$400,000 × 25%$100,000
Remaining long-term gain$2,280,000 × 20%$456,000
Net investment income tax$2,680,000 × 3.8%$101,840
Illustrated federal total$100,000 + $456,000 + $101,840$657,840
Cash after illustrated federal tax$2,880,000 − $657,840$2,222,160

That final amount is a federal-only planning result. Calling it unrestricted after-tax wealth without checking state taxes, closing holdbacks, and personal obligations would overstate what is available.

Why your tax result can differ

Individuals commonly pay 0%, 15%, or 20% on long-term capital gains. The rate depends on their taxable income and the kind of gain. Unrecaptured Section 1250 gain has a maximum 25% rate. That is not a separate 25% charge added to the same dollars already taxed at 20%. [4]

Also, not every item called depreciation recapture uses the 25% ceiling. Some gain is ordinary income under recapture rules, including certain assets identified through cost segregation. Section 1231 rules also combine certain gains and losses. Losses in the past five years can change how current gain is taxed. The asset and tax history must be reviewed before assigning rates. [3]

The 3.8% net investment income tax generally applies to the lesser of net investment income or modified adjusted gross income above the filing-status threshold. It does not apply automatically to every property's full gain. Business participation, deductions, and other facts may matter. [5]

State rules need their own calculation. California, for example, does not give capital gains a special lower rate; it taxes them as ordinary income. That does not mean every other state follows California's approach. [6]

Moving to another state does not by itself end all tax ties to the property. California taxes nonresidents on California-source income, which can include gains from California real estate. Ask how both property location and residency affect your return. [7]

What a 721 contribution may preserve

Return to the hypothetical property. Suppose a partnership agrees to the same $4 million property value. After the $1 million debt and $120,000 of assumed deal costs, the economic credit is $2.88 million in units. At an assumed $100 per unit, that is 28,800 units.

Those contribution costs are an independent assumption. Actual costs may differ from a sale, and each item's tax treatment must be determined. This example uses matching net values to isolate the initial federal tax difference.

Assume the contribution qualifies fully for nonrecognition, including the debt analysis, with no taxable cash or other exception. The contribution then starts with $2.88 million of agreed unit value rather than the sale's $2,222,160 of cash after illustrated federal tax.

The initial difference is $657,840. It is not $4 million of equity preserved, because debt and costs still matter. It is also not a guaranteed $657,840 increase in lasting wealth, because future tax and investment results remain.

Unit value is not tax basis. IRS partnership guidance explains that basis generally carries over from contributed property, with relevant adjustments. A capital account or negotiated equity credit can show a very different number. [8]

That distinction should appear in the paperwork you review. Ask for one schedule showing economic value and another showing tax basis. A neat-looking unit statement is not a substitute for the latter.

A contribution can still create current tax

Do not enter zero tax in a spreadsheet just because the proposal says 721. One key issue is how debt is shared for tax purposes. A decrease in your share of partnership liabilities can be treated as a money distribution. If that net deemed cash exceeds your relevant basis, you may have gain. [9]

Cash paid as part of a property transfer can also create sale treatment. The disguised-sale rules look at related transfers and the surrounding facts. Their two-year presumptions are not a promise that every arrangement outside two years qualifies. [10]

Other exceptions, including the investment-company rule, may affect a proposed contribution. If a company, partnership, or trust owns the property, more rules may apply. The taxpayer who owns the property and the interest being transferred must be clear. [8]

For our example, the zero-current-tax result is an explicit assumption. It is not a conclusion that a $1 million mortgage is safe merely because the property has substantial equity. The basis and debt work must support the result.

Later tax may arrive before you choose to sell units

A qualifying contribution often postpones gain; it does not wipe out the property's history. Section 704(c) tracks built-in gain when contributed property value differs from tax basis. If the partnership later sells that property, some gain can be allocated to you even though you still hold your units. [11]

Other events can matter too, such as a taxable unit redemption, a transfer for REIT shares, or changes in liability allocations. A stated hold period does not promise tax protection. Ask what the actual agreement covers, for how long, and with what exceptions. [8] [9]

Keep annual taxable income separate from cash paid out. You may owe tax on your share of partnership income even when no cash is paid. A contribution does not make all future income tax-free. [19]

For planning, I would want a future-tax column next to the unit-value column. Include a sale by the partnership and an early personal cash need. A plan built only around the best possible exit date leaves out risks you may actually face.

Losses and payment timing can change the comparison

A full taxable sale to an unrelated person can generally release suspended passive losses when the applicable requirements are met. A tax-deferred contribution does not, by itself, release all those losses. Grouping, at-risk limits, and the rest of your tax return can affect the result. [12]

If you have years of unused losses, ask your CPA to run both paths using those records. Comparing a gross tax estimate for the sale with a detailed tax model for the contribution would not be fair.

A sale can also create estimated-tax duties during the year. You may need payments before filing next spring. The IRS explains how withholding and estimated payments work and when penalties can apply. Set the reserve and payment plan with your tax adviser before using the proceeds. [13]

Taxes need not all leave the escrow account on closing day to be real costs. Keep “cash wired at closing” and “cash after expected tax payments” on separate lines.

How to value tax deferral without calling it free money

Deferral can have value because money available today can serve you before a future tax payment. But the benefit depends on time, returns, costs, and the tax ultimately due. A bigger starting account alone does not settle the comparison.

For a pure time-value example, imagine the same $657,840 tax were due exactly ten years later. At a hypothetical 5% annual discount rate, its present value is about $403,857. The difference from paying $657,840 today is about $253,983.

This calculation isolates timing only. It is not a forecast of the tax on OP units, an expected return, or proof that deferral creates that much spendable profit. The eventual tax could change as values, basis, laws, and the owner's circumstances change.

Now think about investment risk. If the partnership underperforms another reasonable use of sale proceeds, some or all of the advantage may disappear. Fees can reduce it too. Conversely, a well-performing investment held for an appropriate period may make the extra invested capital valuable. Neither outcome follows just from Section 721.

A complete model should compare the same horizon and include distributions, fees, ongoing taxes, and a realistic after-tax exit value. If one side includes a sale at the end and the other reports a pre-tax statement balance, the model is incomplete.

Put a value on usable cash and choice

After-tax sale cash can be split among different purposes. You may set aside a home purchase, keep a reserve, and invest the balance. A unit package may keep more value invested while making those choices harder.

Suppose the seller in our example wants $300,000 for family needs. From the $2,222,160 federal-only cash result, that leaves $1,922,160 before state taxes and other adjustments. The 721 side cannot simply subtract $300,000 and assume that amount is available. A cash component or redemption must be feasible and separately reviewed.

Private offerings may restrict transfers and provide no dependable market. The SEC warns that investors can have difficulty selling private-placement securities. Check the particular unit terms rather than describing every 721 investment as semi-liquid. [14]

A sale also lets you choose whether to remain in real estate. A contribution typically requires accepting the chosen partnership's properties, debt, management, and fees. More capital in an investment you do not want is not a useful goal by itself.

Treat estate planning as a separate analysis

Inherited property generally receives a basis tied to date-of-death value, subject to exceptions and other valuation rules. That can be a step down as well as a step up. It is not a benefit available only to OP units; other qualifying inherited assets may receive basis adjustments too. [15]

Partnerships add another issue. An heir's basis in the inherited partnership interest is separate from the partnership's basis in its buildings. Section 743(b) may provide a basis adjustment for that heir. A Section 754 election may be needed. Do not assume the inside property basis automatically resets for everyone. [16] [17]

Ask what the partnership will do when an owner dies and what records the executor must supply. Also consider whether heirs need cash, whether the units can be divided or transferred, and who will handle future tax reporting.

“Hold until death and all taxes vanish” is not a sound substitute for that work. Estate costs, taxable income, the governing documents, and the family's needs still require attention.

Compare real alternatives before choosing

If you want replacement real estate, a properly planned 1031 exchange may be another option. Ordinary OP units and REIT shares are not qualifying 1031 real property. The regulation's narrow treatment of certain valid Section 761(a) arrangements does not make a normal UPREIT interest eligible. [18]

You may also keep the property, use a different manager, or sell one separately owned property while considering a contribution of another. A mixed transaction involving cash and units needs its own analysis; a simple percentage split does not determine the tax.

Consider two owners with the same property numbers. One has a large cash reserve and wants less daily work. The other needs most of the sale proceeds to fund a home and family support. The first may have room to assess a long-term unit investment. The second may need a sale even when the tax cost is high. Equal gains do not create equal needs.

For each owner, write down the amount that must be available by a firm date. Then test whether the plan can supply it without relying on a hoped-for buyer, a future loan, or a redemption that can be delayed. A tax benefit should not leave a basic family need unfunded.

Compare actual bids as well. The highest property valuation may be paired with costly units or restrictive terms. An all-cash buyer may offer a lower price with fewer conditions. Until you compare net proceeds and what you receive, the headline prices tell only part of the story.

What I would want on one comparison sheet

Mark assumptions in plain view. Change them one at a time: a lower valuation, higher cost, shorter hold, or earlier cash need. If the preferred choice changes after a small adjustment, that sensitivity belongs in the conversation.

I would rather see a clear range with honest limits than a precise tax-savings number built on missing information. The purpose is to choose an outcome you can live with, not to make one column look larger.

Frequently asked questions

Is my taxable gain the same as my equity?

No. Gain depends on the amount realized and adjusted basis. Equity reflects value less debt. The mortgage payoff reduces closing cash but generally is not a separate deduction from sale gain. [2] [3]

Does selling always cost one-third of the gain in tax?

No. Gain character, income, losses, state rules, and other facts affect the result. The rates used in this article's example are stated assumptions, not a standard combined rate for property owners. [4] [5]

Does a 721 contribution keep the full property price invested?

Not as your net equity. Debt, fees, and other closing adjustments affect the unit value you receive. In the example, a $4 million property produces $2.88 million of unit credit, not $4 million.

Can I pay tax while I still own OP units?

Yes. Partnership income, a property sale, or certain liability changes can create taxable items before you sell your units. Tax-protection terms need careful review and do not remove every tax event. [8] [9] [11]

Can suspended rental losses make a sale more attractive?

They can change the tax result. A qualifying full taxable disposition to an unrelated person generally can release suspended passive losses. Have your CPA check the actual activity, grouping, and other limits. [12]

Will heirs automatically avoid all deferred tax?

No. Inherited-interest basis and inside partnership basis are separate. Valuation, Section 743(b), a possible Section 754 election, and exceptions matter. A basis adjustment is not a guarantee of cash or freedom from every tax. [15] [16] [17]

When might paying the sale tax be reasonable?

When after-tax cash meets your needs better, the available partnership is unsuitable, or you need flexibility the units cannot provide. Tax deferral is one benefit to evaluate alongside investment quality, costs, control, and access to money.
