Sell a Rental to Fund a Business? Pay the Tax, Do a Partial Exchange or Borrow Against the Replacement

Decide how much the business needs and when, because each route delivers cash at a different time

A taxable sale or a partial exchange puts money in your hands at closing. A borrow-after route delivers it only once the replacement is bought and a lender funds, which can be weeks or months later. A business purchase with a fixed closing date may decide the route for you.

Also decide whether the money is equity or could be a business loan. If the business itself can borrow, keeping the rental equity invested and deferred may cost less than any of the three routes; 1031 vs a cash-out refinance compares the two for owners who want to keep the property.

One more option suits owners whose business needs a building. Section 1031 covers real property held for productive use in a trade or business, so exchanging the rental into the building your business will occupy keeps the gain deferred and puts the equity to work for the company, as long as you own it and lease or use it in the business.

A partial exchange taxes the cash you take, up to your gain, and defers the rest

Publication 544 explains the rule: in a like-kind exchange where you also receive money, you recognize gain equal to the smaller of the gain realized or the money and other property received. The rest of the gain is deferred under section 1031 and carried into the replacement's basis.

Take the cash at the sale closing, not later. Reg. section 1.1031(k)-1(g)(6) requires the exchange agreement to deny you any right to receive, pledge, borrow or otherwise get the benefit of funds held by the qualified intermediary before the exchange period ends, except in narrow cases. Cash you need must come off the closing statement before the rest goes to the intermediary.

Boot can also come from debt you do not replace. Under Reg. section 1.1031(d)-2, debt paid off at the sale is treated as money received, and the regulation's Example 2 says cash you receive is not offset by debt you take on with the replacement. So you cannot take $250,000 out and fix it by borrowing $250,000 more on the new property. Boot taxed as recapture or capital gain first explains which layer the boot hits.

Worked model: $250,000 for a business from a $1,000,000 rental

Hypothetical round numbers. A rental sells for $1,000,000 net of selling costs, with a $300,000 mortgage and a $400,000 adjusted basis, so the gain is $600,000 and the equity is $700,000. The owner needs $250,000 for a business. Run your own numbers with your CPA.

• Taxable sale: all $600,000 of gain is taxed, including the depreciation layer at up to 25% and net investment income tax if income is above the threshold. The owner keeps $700,000 less tax.
• Partial exchange: $250,000 comes off at closing, $450,000 goes to the intermediary, and the owner buys a $750,000 replacement with $450,000 of exchange funds and a new $300,000 loan. Recognized gain is $250,000; the other $350,000 is deferred.
• Full exchange, then borrow: all $700,000 goes to the intermediary and the owner buys a $1,000,000 replacement with a $300,000 loan, deferring the full $600,000. After closing, a $250,000 loan against the replacement funds the business, adding about $250,000 of debt and its interest cost.
• The partial exchange costs tax on $250,000 now. The borrow-after route costs interest and leverage risk, and depends on a lender agreeing.

Borrowing against the replacement keeps the deferral, and the interest follows the money

Under Reg. section 1.163-8T, debt is allocated to expenditures according to how the proceeds are used, even if the loan is secured by other property. A loan secured by your replacement rental and spent on the business is business debt, and its interest is a business expense, subject to the usual limits. Keep the proceeds in a separate account and spend them directly on the business so the trail is clean.

Two cautions. First, a refinance arranged at the same time as the exchange closing, or promised in the purchase, invites the question of whether the cash really came from the exchange; leave time between them and get your CPA's sign-off on the timing. Second, a DST interest is hard to borrow against, so this route usually means a directly owned replacement; see pledging a DST as collateral.

For the business itself, the SBA's 7(a) program guarantees loans up to $5 million for uses that include working capital and business real estate. An SBA lender will ask how much of your own money goes in, so the rental decision and the loan application should be planned together.

Where a cash out DST fits, and what to ask before relying on it

Our cash out DST page describes zero cash flow, high-leverage DSTs built for investors who want to free capital for other ventures or solve a debt-replacement requirement with a small part of their proceeds. The loans are non-recourse, so only the invested capital is at risk, and investors receive no current distributions; any payout comes when the property is sold. Zero cash flow DSTs explained covers the structure.

Ask for the offering documents before counting on the cash: how and when any liquidity reaches you, how it is taxed, and what happens to your equity if the property's value falls under the debt. Higher leverage raises that risk. Pulling cash out after a 1031 covers the general timing questions.
