What an assignment of contract actually is
When you sign a purchase agreement with a seller, you acquire equitable interest — a contractual right to buy that property at a set price by a set date. An assignment of contract sells that right to someone else. You are the assignor; the buyer taking over is the assignee. They step into your position, close directly with the seller under the original terms, and take title. You never own the house, never appear in the chain of title, and never bring purchase funds.
This is the core mental shift for a newer wholesaler: the product you're selling is the contract, not the property. Your negotiated price, your inspection window, your closing date — those terms are the asset. A tight contract on a mediocre house is more sellable than a sloppy contract on a great one, because the assignee inherits your terms exactly as written.
The two documents that make it work
An assignment involves exactly two agreements, and most blown deals trace back to a defect in one of them.
The purchase agreement (you and the seller)
This is the underlying contract with the off-market seller, and it has to be assignable. In most states, contracts are assignable by default unless they say otherwise — but never lean on the default. Write it in: either an explicit clause ("Buyer may assign this agreement") or "and/or assigns" after your name as buyer. While you're in there, negotiate the other terms that make an assignment sellable: an inspection period long enough to run your sales process, an earnest money deposit you can afford to have tied up, and a closing date with enough runway to find a buyer and let them actually close.
The assignment agreement (you and the end buyer)
This is the document that transfers your position. It should identify the original purchase contract (attach it as an exhibit), name assignor and assignee, state the assignment fee and when it's paid, and require a non-refundable assignment deposit from the assignee. It should also spell out default in both directions: what happens if the underlying deal collapses on your end, and what the assignee forfeits if they don't close. Pay an attorney in your state to draft this once; reuse it on every deal after.
What the assignor stays on the hook for
Assigning the contract does not automatically make you a bystander. A standard assignment transfers your rights; whether it releases your obligations depends on the language and on your state. In many plain-vanilla assignments, if the assignee fails to close, the seller can still look to you — you're the one who signed the original contract. A full release requires the seller's agreement to substitute the new buyer (a novation), which most wholesale assignments never bother with. Know which one you're signing.
- Earnest money: your deposit usually stays in escrow until closing. Structure the assignment deposit or fee so you're made whole if the assignee takes over the file.
- Disclosure to the seller: put your intent to assign in the contract itself. Several states now require wholesalers to disclose that they hold a contract, not title — and some restrict marketing the property versus marketing the contract.
- Performance risk: if your assignee walks and you can't replace them in time, you're the one holding a contract with a closing date on it.
What the assignee takes on
The assignee steps into the contract exactly as written. Price, closing date, contingencies, property condition — whatever you negotiated is what they get. If your inspection window already expired, they're buying without one, which is why serious buyers want to walk the property or see your photos, scope, and comps before they sign. Expect them to underwrite against ARV and repair costs the same way you should have when you contracted it — if your numbers don't survive their underwriting, no assignment agreement will save the deal.
From your side, the assignee is the single biggest risk in the transaction, so verify before you assign. Proof of funds is a screenshot; closed deals on record are evidence. It's why Buy Box Cartel counts its cash buyers the hard way — 3,418 verified buyers, where verified means an investor whose purchase we can point to in public deed records, not a name on a rented list. Whatever your buyer source, hold it to that standard: has this person actually taken title on a deal like this one?
Then make the assignment deposit non-refundable and large enough to hurt. A buyer with nothing at stake will drop your deal the moment a shinier one hits their inbox; a buyer with real money committed either closes or forfeits it.
How the money moves at closing
The assignment fee is your spread: the difference between your contract price with the seller and the price the assignee agreed to pay. In the clean version, the fee runs through the title company or escrow — it shows up as a line item on the settlement statement, the assignee's funds cover it, and you get paid when the deed records. Resist any arrangement that pays you outside closing. If the deal never closes, informal side agreements are worth exactly the paper they're written on.
For calibration: the average assignment fee on deals closed through the Buy Box Cartel platform is $6,704. Individual fees swing well above and below that depending on the spread you negotiated — but the mechanism is always the same line on the same statement.
One consequence of that line item: everyone sees it. The seller learns what you made, and so does the buyer. On a typical fee that's a non-event — the buyer priced their maximum before your fee existed, and the seller is getting the price they agreed to. On an outsized fee, it can become an event, which is exactly where the assignment-versus-double-closing decision lives.
When assignment beats a double closing
A double closing is the alternative exit: you actually buy the property from the seller and resell it to your end buyer in two back-to-back closings, minutes to days apart. You take title briefly, you need funds for the first leg (usually transactional funding), and you pay closing costs twice. In exchange, your profit is invisible — the buyer sees a purchase price, not a fee.
Assignment wins most of the time because it's cheaper and simpler:
- One closing, one set of closing costs, no purchase funds, no transactional-funding fee.
- Faster to execute — no coordinating two settlements and a same-day funding wire.
- No moment on title, which means no second transfer-tax hit in states that charge one per transfer, and one less transaction on your books.
Double closing earns its extra cost in three situations: the fee is large enough that showing it on the settlement statement could blow up the deal at the table; the underlying contract prohibits assignment (bank-owned, HUD, and new-construction contracts commonly do); or the end buyer's lender won't fund a purchase with an assignment fee attached. If none of those apply, assign — every dollar the double close spends on its second closing comes straight out of your spread.
Where assignments die
The mechanism is simple; the failure modes are predictable. Watch for these:
- No assignability language. You marketed a contract you can't legally transfer. Fix the clause before you sign, not after a buyer says yes.
- Daisy-chaining. Assigning a deal you don't control — someone else's contract, or an assignment of an assignment — multiplies the ways the chain breaks and torches your name with buyers who trace it back.
- An unverified buyer. No deed record, no deposit, no close. The pattern is that reliable.
- Fee greed. If your fee leaves the assignee thin against their own numbers, they'll retrade you at the deadline or walk. Price the contract so the buyer still wins the deal.
- Slow dispo. Every day of your contract period that passes without a committed buyer shrinks your leverage — buyers can smell an expiring closing date, and they price it.
The structural fix for the last two is having buyers before you need them. Build and work your own list, or take the contract where buyers already are: you can sell your wholesale contract through Buy Box Cartel's JV lane at $0 upfront — the dispo team markets it to the buyer network and takes a cut only when the deal closes. No close, no fee. Either way, remember the order of operations: the assignment paperwork is the easy part. The buyer is the deal.
