A simultaneous closing is a pair of back-to-back real estate transactions where an investor buys a property from the original seller and immediately resells it to an end buyer, usually within the same hour at the same settlement table. The investor’s profit is the spread between the two prices, minus two sets of closing costs and any short-term financing fees. The structure is common in wholesaling: three parties, two contracts, two deeds, and a closing agent who runs both settlements in sequence.
The Three Parties and Two Deeds
Every simultaneous closing has three participants. Party A is the original seller. Party B is the investor or wholesaler. Party C is the end buyer. The first transaction moves title from A to B. The second moves it from B to C. Both close in sequence, minutes apart.
Party B actually takes title, even if only briefly. The closing agent prepares two separate deeds, runs two title searches, and produces two settlement statements. The investor keeps whatever remains from the B-to-C proceeds after paying the A-to-B purchase price, both sets of closing costs, and any financing charges.
How It Differs From a Contract Assignment
The other way to flip a contract is to assign it. In an assignment, the investor never takes title. The investor signs over the right to purchase to the end buyer, who closes directly with the original seller, and the investor collects an assignment fee at closing. One transaction, one deed.
A double closing is two full transactions and two recorded deeds. The main reason investors choose it is privacy. The original seller doesn’t see what the property resells for, and the end buyer doesn’t see what the investor paid. On an assignment, both sides can see the markup on the settlement statement, and deals sometimes collapse when a seller or buyer objects to the fee. Double closings also work around contracts that prohibit assignment, since the investor is genuinely buying and reselling rather than transferring a contract.
The tradeoff is money and complexity. Two closings mean two sets of fees, two title searches, and usually transactional funding charges. If the spread is thin, an assignment often makes more sense.
Funding the Middle Transaction
This is where most of the difficulty lives. The A-to-B purchase has to be fully funded before the B-to-C closing can proceed. Investors often ask whether they can just use the end buyer’s money to pay the original seller. In most cases, no. Title insurers typically require the A-to-B purchase to be funded with money that doesn’t come from the B-to-C proceeds, and lenders backing the end buyer’s mortgage almost always prohibit their funds from being used to close someone else’s purchase.
The investor needs independent capital to bridge the gap, even when the gap is measured in minutes. The common solution is transactional funding, a short-term loan built for double closings. The transactional lender wires the full A-to-B purchase price plus closing costs to the closing agent, the A-to-B transaction closes, and the lender gets repaid out of the B-to-C proceeds as soon as that second closing funds. The whole loan usually lives under 24 hours.
Transactional lender fees typically run 1% to 2.5% of the loan amount, sometimes with minimums around $2,500. The fee comes out of the B-to-C proceeds. The lender also provides a proof-of-funds letter to the closing agent confirming that the A-to-B money is available and not dependent on the end buyer’s funds. Investors with cash reserves can self-fund the A-to-B side instead and skip the fee, but most wholesalers use transactional funding to preserve liquidity.
The Closing Day Sequence
The order on closing day is rigid. The A-to-B transaction closes first. The investor and the original seller sign the deed, settlement statement, and closing documents. The transactional lender’s funds, or the investor’s own cash, are disbursed to the seller, clearing any existing liens. The closing agent holds the A-to-B deed for immediate recording.
Once the A-to-B side is funded, the B-to-C closing begins. The investor signs a new deed transferring the property to the end buyer, and both sides sign the B-to-C settlement statement. The end buyer’s funds flow into escrow, and the closing agent disburses them in order: first repaying the transactional lender’s principal and fees, then paying closing costs, and finally wiring the investor’s profit.
Title insurance deserves attention up front. Some title companies will insure both transfers, but many are cautious about simultaneous closings because the speed of the transaction makes risk harder to evaluate. Investopedia notes that some companies refuse to insure the title during a simultaneous close because the accelerated process makes creditworthiness harder to determine.1Investopedia. How a Simultaneous Closing Works in Real Estate Confirm well in advance that the title company will handle the transaction and issue policies for both transfers. Switching title companies mid-deal is painful and can spook the end buyer.
Setting Up the Contracts
Both purchase agreements need to be written with the simultaneous structure in mind. The A-to-B contract should include a contingency tying the investor’s obligation to purchase to the successful closing of the B-to-C sale. Without that clause, the investor is on the hook for the purchase price if the end buyer disappears. The B-to-C contract should set a closing date and time that lines up with the A-to-B closing.
It’s good practice to disclose to the end buyer that the investor is acquiring the property immediately before reselling it. Transparency here reduces the risk of later claims that the investor misrepresented the deal, and in some states this kind of disclosure is required.
Costs That Get Doubled
Two closings mean two sets of costs. Every fee that applies to a normal real estate transaction gets charged twice: title search fees, settlement agent fees, recording fees for both deeds, and often title insurance premiums for both transfers. In states with a real estate transfer tax, the tax applies to each conveyance separately. The investor pays it on the A-to-B side, and the end buyer pays it on the B-to-C side.
Add transactional funding fees on top. Recording fees, settlement fees, and transfer tax rates all vary by jurisdiction, so the total varies too, but the overhead of a double closing typically runs several thousand dollars more than a single sale would. If the spread between the two prices can’t absorb those costs, the deal doesn’t work. Experienced wholesalers build a detailed cost worksheet before signing the A-to-B contract.
When the End Buyer Uses a Government-Backed Mortgage
The biggest compliance issue is what happens on the B-to-C side when the end buyer’s financing is government-backed. The Federal Housing Administration has a property flipping rule that makes a property ineligible for FHA-insured financing if it’s resold within 90 days of acquisition. For resales between 91 and 180 days, FHA may require a second appraisal when the resale price exceeds a threshold percentage above the original purchase price.2U.S. Department of Housing and Urban Development. Property Flipping
That effectively blocks the B-to-C side of a simultaneous closing when the end buyer is using FHA financing, because the investor’s ownership period is measured in minutes rather than months. Limited exemptions exist for sales by HUD or other government agencies, approved nonprofits, and inherited properties, but none of those typically apply to a standard wholesaling transaction.
Fannie Mae doesn’t impose the same bright-line 90-day restriction on conventional loans, but its selling guide requires lenders to document that the property seller actually owns the property, and it specifically flags back-to-back closings, simultaneous closings, and double escrows as transactions warranting extra scrutiny.3Fannie Mae. Lender Responsibilities Some conventional lenders add their own internal flipping restrictions as overlays even when Fannie doesn’t require them.
The practical result: simultaneous closings run most smoothly when the end buyer is paying cash or using a lender that doesn’t apply seasoning restrictions. When FHA financing is involved, the investor generally has to hold the property for at least 90 days, which turns the deal into a standard flip rather than a simultaneous close.
State Licensing and Disclosure Rules
A growing number of states regulate real estate wholesaling. Some require a real estate license to publicly advertise a property you don’t yet own. Others restrict unlicensed individuals from performing more than a set number of wholesale transactions per year. Illinois, Arizona, Oklahoma, and New York have been among the more active states in enforcing restrictions on unlicensed wholesaling activity.
Many jurisdictions also require the intermediate seller to disclose that they’re acquiring the property immediately before reselling, and some require disclosure of the profit margin. Failing to disclose can expose the investor to claims of fraud or misrepresentation. In heavily regulated states, some wholesalers actually prefer double closings because taking title avoids the legal issues that come with marketing a property you don’t own, which is the main regulatory trigger for assignment-based wholesaling.
How the Profit Is Taxed
Profit from a simultaneous closing is almost always taxed as ordinary income. The investor holds the property for less than a day, so there’s no route to the long-term capital gains rate, which requires holding an asset for more than a year. For 2026, ordinary federal income tax rates run from 10% to 37% depending on total taxable income.4Tax Foundation. 2026 Tax Brackets and Federal Income Tax Rates
The bigger tax question is dealer classification. The IRS distinguishes between real estate investors, who buy and hold for appreciation or rental income, and real estate dealers, who buy property with the intent to resell for profit as a regular business. Repeated simultaneous closings will likely land an investor in dealer status. Dealer profits are ordinary income and also subject to self-employment tax. Under federal law, income from real estate sales received in the course of a trade or business as a real estate dealer is included in net earnings from self-employment.5Office of the Law Revision Counsel. U.S. Code Title 26 – 1402 Self-employment tax is 15.3% (12.4% Social Security plus 2.9% Medicare) on net earnings up to the Social Security wage base, and 2.9% above that. A tax professional can advise on whether an entity structure like an S-corp reduces self-employment tax exposure.
Risks That Kill Deals
The single biggest risk is that the B-to-C buyer fails to perform on closing day. If the end buyer can’t close, the investor is stuck holding a property bought with transactional funding that demands immediate repayment. The contingency clause in the A-to-B contract protects against this only if the A-to-B side hasn’t already funded. Once the investor’s name is on the deed and the seller has been paid, there’s no unwinding the first transaction.
Timing creates its own pressure. Both closings usually need to happen during the same business day, within banking wire hours. If the A-to-B closing runs late because of document errors, missing signatures, or a wire delay, the B-to-C side can slip past the wire cutoff and push to the next business day. That delay can trigger default provisions in the transactional loan or cause the end buyer to walk.
Title company refusal is another common stumbling block. Not every firm handles simultaneous closings, and some that do impose conditions that make the deal impractical. Get a firm written commitment from the closing agent before signing either contract, and make sure the math still works after every fee line item is accounted for.
