An assignment contract is a legal agreement that lets one party transfer their rights and obligations under an existing contract to another party. In real estate, you'll also hear it called an "assignment of contracts" both terms refer to the same thing.
To understand how it works, you need to know the three people involved:
The assignor never actually purchases the property. Instead, they sell their right to buy it to the assignee, who then closes the deal with the seller directly.
This is what sets it apart from a traditional real estate transaction. In a standard purchase, there are two parties — a buyer and a seller — and the buyer who signs the contract is the same person who shows up at closing. With an assignment contract, the buyer who originally signed the deal steps aside before closing and hands that position over to someone else.
An investor finds a motivated seller willing to accept $180,000 for their home. The investor signs a purchase contract for that amount but includes a clause that allows the contract to be assigned. Before closing, the investor finds another buyer willing to pay $195,000 for the same property. The investor assigns the contract to that new buyer for a $15,000 assignment fee. The new buyer closes the deal with the seller at $180,000, and the investor walks away with $15,000 — without ever owning the property.
Step 1: The Assignor Finds a Property The assignor — usually an investor or wholesaler — identifies a property being sold below market value. This often means working with motivated sellers who need to close quickly or simply want out of the property fast.
Step 2: They Sign a Purchase Contract The assignor enters into a purchase agreement with the seller. This contract includes an assignability clause, which is a provision that explicitly allows the assignor to transfer their position in the contract to another buyer. Without this clause, the assignment may not be permitted.
Step 3: The Assignor Finds an End Buyer While still under contract, the assignor markets the deal to potential buyers — typically other investors looking for properties at a good price. The goal is to find someone willing to pay more than the original contract price.
Step 4: The Assignment Agreement Is Signed Once an interested buyer is found, the assignor and assignee sign a separate document called the assignment agreement. This is different from the original purchase contract. It outlines the terms of the transfer, including the assignment fee the assignee will pay the assignor.
Step 5: The Assignee Closes the Deal The assignee steps into the assignor's place and closes the transaction directly with the seller at the originally agreed price. The assignor is no longer part of the deal at this point.
The original terms stay intact. The price, contingencies, closing date, and any other conditions that were agreed upon between the assignor and the seller all carry over. The assignee simply takes on those same obligations. They are now responsible for completing the purchase exactly as the original contract outlined.
The assignment fee is how the assignor gets paid. It is the difference between the price the assignor locked in with the seller and the price the assignee agrees to pay for the contract. Using the earlier example, if the original contract was at $180,000 and the assignee pays $195,000 to take it over, the $15,000 difference is the assignment fee. This fee is typically paid at closing.
Why Not Just Find a Buyer and Collect a Referral Fee?
The problem is that referral arrangements are informal. Once you connect both parties, there's nothing stopping them from proceeding without you — and without paying you. Unless you have a written agreement locked in beforehand, that fee isn't guaranteed.
An assignment contract removes that risk entirely. Your position in the deal is legally protected from the moment you sign, and your fee is agreed upon in writing before closing. There's no relying on goodwill or a handshake arrangement.
The earning potential is also worth considering. Referral fees tend to be modest. An assignment fee is negotiated on your own terms, kept in full, and can be significantly higher depending on how good the deal is.
Who Uses Assignment of Contracts and Where?
Wholesalers are the most frequent users of this strategy. Their job is to find properties being sold under market value — often from motivated sellers dealing with financial hardship, inherited properties, or homes needing significant repairs. They lock in the purchase price, find an end buyer willing to pay more, and assign the contract for a fee. They never own the property, carry a mortgage, or deal with renovations.
Real estate investors use the same approach, sometimes assigning deals that don't fit their current portfolio rather than passing on them entirely.
Assignment of contracts also appears in commercial real estate transactions. Investors working with office buildings, retail spaces, or multi-unit properties sometimes use assignments when they want to secure a deal during due diligence but aren't ready to commit to closing. Assignment clauses are common in commercial deals, and the fees involved tend to be significantly higher than in residential transactions.
This is where everyday buyers encounter assignment contracts most often. When developers sell units before a building is finished, buyers sign purchase agreements months or years ahead of closing. If a buyer changes their mind, they can assign the contract to someone else rather than forfeit their deposit — and may collect a fee if the property has appreciated. This is especially common in high-demand markets for condos or townhomes where values rise significantly during the construction period.
Assignment contracts can be a smart strategy, but they are not without their pitfalls. Whether you're the assignor or the assignee, there are a few important things to understand before moving forward with a deal.
Not every contract can be assigned. Some sellers include a non-assignability clause in the purchase agreement, which means the buyer cannot transfer their position to anyone else. This is more common than people think, especially with bank-owned properties, foreclosures, and deals involving institutional sellers.
If you're planning to use an assignment strategy, the first thing to check is whether the contract actually allows it. Assuming it does without verifying can cost you the deal — and possibly your earnest money deposit.
In a traditional purchase, the buyer has time to inspect the property, review disclosures, and do their homework before closing. In an assignment deal, the assignee is stepping into a contract that someone else negotiated. If the original assignor didn't do thorough due diligence, the assignee may inherit problems they didn't see coming — structural issues, title complications, or unfavorable contract terms that are difficult to renegotiate at that stage.
Assignees should always review the original contract carefully and, where possible, conduct their own inspections before agreeing to take over. Don't assume the assignor has covered everything.
The legality of assignment contracts varies by state and by context. In most cases, assigning a contract is perfectly legal as long as the contract permits it and the assignor is selling their contractual rights rather than acting as an unlicensed real estate agent.
However, problems can arise when the line gets blurry. If an assignor is regularly marketing properties they don't own and collecting fees without a license, some states may view that as practicing real estate without proper credentials. The rules differ depending on where you are, so it's important not to assume that what's acceptable in one state applies in another.
There's also an ethical side to consider. Sellers — particularly motivated sellers in difficult situations — may not fully understand that their buyer plans to assign the contract to someone else. Being transparent about your intentions from the beginning protects everyone involved and helps avoid disputes down the line.
Given the moving parts involved, working with a real estate attorney is one of the smartest things either party can do. An attorney can review the contract for assignability, draft or review the assignment agreement, flag any red flags in the terms, and make sure the transaction complies with local laws.
This is especially important for first-time assignors or assignees who are unfamiliar with how these deals are structured. The cost of a legal review is minor compared to the cost of a deal gone wrong.
Generally, no. When you assign a contract, you're selling your own contractual rights — not representing another party as an agent. That distinction typically keeps it outside the scope of activities that require a license.
That said, repeatedly finding properties, putting them under contract, and assigning them for a fee may be interpreted as brokering without a license in some states. If you plan to use this strategy more than once, it's worth consulting a real estate attorney in your state first.
Not always. It depends on what's written in the contract. If there's an assignability clause, you're good to go. If there's a non-assignability clause — or the contract doesn't address it at all — you'll likely need the seller's written consent before proceeding.
Bank-owned properties and government-backed transactions are almost always non-assignable by default. Reading the contract carefully before signing is the only way to know for sure.
Conclusion
Assignment contracts are a legitimate and widely used tool in real estate, but they work differently from a standard property purchase. Instead of buying and selling a home outright, the assignor transfers their position in a purchase contract to a new buyer — walking away with an assignment fee without ever owning the property.
The strategy is most popular among wholesalers and investors, but it also shows up in commercial deals and pre-construction sales. When used correctly, it can be a fast and efficient way to profit from a good deal. When used carelessly, it can lead to legal trouble, lost deposits, or deals that fall apart at closing.
The key things to keep in mind are simple. Make sure the contract allows assignment before moving forward. Do your due diligence whether you're the assignor or the assignee. Understand that the rules around licensing and legality vary depending on where you are. And when in doubt, get a professional involved.
Speaking with a real estate attorney before your first assignment deal is always a good idea. The strategy has real potential, but like most things in real estate, the details matter. Going in informed — and with the right people in your corner — puts you in a much better position to make it work.
