Can I Use 1031 Exchange to Pay Off Mortgage? 

Can I Use 1031 Exchange to Pay Off Mortgage? 

April 13, 2025 | Written and reviewed by , CPA, California Board of Accountancy License #56113

In a bold move that offered clarity to gray areas in 1031 exchanges, Earlene Barker petitioned the US Tax Court, challenging the Internal Revenue Service’s (IRS) decision to revoke her transaction’s tax deferral status. The IRS argued that she had used part of the sale proceeds of her relinquished property to pay off her mortgage. 

Undeterred throughout the 6-year-long legal battle, Barker and her legal team proved that by taking up a new mortgage for the replacement property she acquired, she satisfied rules guiding mortgage boots in 1031 exchanges. Her eventual victory in court set a precedent that made it easier to pay off mortgages during 1031 exchanges. 

But it’s not as straightforward as it seems. In fact, when you use this strategy, you stand a better chance of creating a taxable event than getting tax deferral, unless you’re working with an experienced and highly competent Qualified Intermediary (QI).

This article explains what a 1031 exchange means, answers common questions about the payment of mortgages during such transactions, and offers guidance on how to successfully handle like-kind exchanges without incurring mortgage boot.

What Is a 1031 Exchange?

What Is a 1031 Exchange?

A 1031 exchange is a legal strategy of deferring taxes when buying and selling real properties. Backed by Section 1031 of the Internal Revenue Code, the exchange process involves using the proceeds of a relinquished property to acquire replacement properties. As part of the rules guiding the exchange, only like-kind properties can be exchanged. 

Like-kind in this context refers to real estate properties held for commercial and investment purposes. That means you cannot exchange a rental property for a car, equipment, or non-real estate assets. In the same vein, you cannot sell your personal residence or buy another taxpayer’s personal property through this process. In fact, no real property held for personal use is qualified to be transacted as a 1031 exchange. 

Another important factor in a successful 1031 exchange is the services of a Qualified Intermediary. In very clear terms, you cannot do a tax-deferred exchange without a QI. The QI facilitates the entire exchange process and is responsible for holding the proceeds from the relinquished property’s disposition and using them to acquire potential replacement properties. This simply means that the investor(s) cannot receive exchange funds throughout the process without incurring tax liabilities.

Can You Use a 1031 Exchange to Pay Off a Mortgage?

This question has two answers: Yes and No

  • Yes, because when selling your relinquished property, all mortgages on it are typically paid off at closing costs.
  • No, because paying off the mortgage from the sale proceeds exposes you to potential tax liability. The IRS will require you to pay taxes immediately on the mortgage sum, since it’s considered part of the taxable gain you took from the sale. To avoid this, you may have to take up a new mortgage on the replacement property.

To understand this better, we will look into how mortgages work in 1031 exchanges, especially as it pertains to loan boot.

How Does a 1031 Exchange Work With Mortgage Debt?

According to Section 1031 of the tax code, all proceeds from the sale of your relinquished property must be reinvested into a like-kind replacement property with an equal or greater value. This means you’re not permitted to take away any dime from the sale proceeds to offset a loan or mortgage debt. 

In fact, any money from the relinquished property’s disposition that is not invested into the new replacement property is considered a “cash boot” and is liable to immediate tax. Suppose you have an existing mortgage of $200,000 on your property, and decide to sell the property in a 1031 exchange for $500,000.

Upon completion of the deal, $200,000 from the sale proceeds will go into paying off the mortgage, leaving you with a balance of $300,000. The action you take afterward will determine whether you will pay an immediate tax. So let’s explain the possible actions under the following scenarios:

Scenario One

You bought a real property of $300,000 and paid in full without a mortgage. This will signal the IRS that you didn’t invest the entire $500,000 from the relinquished property sale into the replacement property. The balance of $200,000, which went into the mortgage payment of the old property, becomes your mortgage boot. And you may have to pay an immediate capital gains tax on it.

Scenario Two

You bought a property with a fair market value exceeding $300,000 but less than $500,000—say $450,000. In this case, you didn’t pay in full. Instead, you made a down payment using the available $300,000 and took a mortgage of $150,000 to finance the deal. Since the new mortgage is not up to the former mortgage, the transaction will trigger a taxable event.

The mortgage boot here will be: Old Mortgage – New Mortgage = $200,000 – $150,000 = $50,000.

Hence, you will pay immediate capital gains taxes on the $50,000 mortgage difference.

Scenario Three

You bought a new investment property of $500,000 or above, paid $300,000, and took a mortgage of $200,000 or more. Since the 1031 debt rules require the mortgage on the new exchanging property to be higher than the one cleared from the relinquished property, the IRS will interpret it as no taxable gain was withdrawn from the transaction. In this case, you are absolved from any immediate tax exposure.

Scenario Four

Here, you used additional cash ($200,000) to clear the mortgage before or at the close of the deal, without relying on the $500,000 from the exchange proceeds to do so. This influx of new cash will allow you to buy a new asset of $500,000 without taking a new loan or paying immediate tax.  

How to Avoid a Taxable Boot When Managing Mortgage Debt

How to Avoid a Taxable Boot When Managing Mortgage Debt

While there are several ways to avoid taxable boot when managing mortgage debt in a 1031 exchange, the four we will discuss in this section are straightforward and pose the least IRS compliance challenges. The first strategy is to use additional cash to pay off the mortgage before or during the sale of the relinquished property. You can only adopt this strategy if you have the funds available.

The second strategy is known as mortgage assumption. It involves purchasing a replacement property with an equal or higher existing mortgage. For this to work, your Qualified Intermediary must prepare proper documentation showing that you’re assuming or taking over the mortgage on the replacement property from the seller. Of course, this needs the approval of the lender to scale through. 

This option ensures that the full mortgage amount from the relinquished property is covered. It also gives you more options to buy a bigger or more valuable property using cash-out refinancing. What this shows to the IRS is that everything from the sale, including debt, has been fully reinvested, thereby meeting one of the main rules for a proper 1031 exchange and full tax deferral. 

The third strategy is to pay off the mortgage on your relinquished property using the proceeds from its sale and then take up another mortgage to finance the purchase of a like-kind replacement property. The new mortgage must be of equal or greater value than the former one.

If taking on more debt during the 1031 exchange does not align with your investment plans, you can decide to use your funds to complete the purchase and avoid mortgage boot. Once the deal is completed and all IRS compliance requirements are satisfied, you can proceed to refinance the property.

Refinancing, as a strategy, means taking out a new loan on the new valuable property after the 1031 exchange is finished. This allows you to remove your invested personal cash tax-free without breaking any IRS rules. Due to its complex procedure, working with trustworthy escrow companies and renowned exchange facilitation companies is essential to ensure all funds are properly handled and the transaction follows IRS rules.

Alternative Ways to Manage Mortgage Debt in a 1031 Exchange

Although the most common way to handle a debt mortgage in a 1031 exchange is by replacing it with an equal or higher debt volume, it isn’t necessarily the only option. There are different alternative strategies depending on your investment plans and financial status that can help you manage debt effectively while still ensuring full tax deferral. These options include seller financing, using rental income, and investing in Delaware Statutory Trusts (DSTs).

Seller Financing

In seller financing, commonly known as “seller carryback financing”, the seller of an investment property agrees to loan part of the purchase price to the investor trying to purchase the property. At the end of the exchange, the buyer, with the aid of a QI, gives a down payment with a signed promissory note (also known as a “seller carryback note”) to the seller.

This note is secured either by a deed of trust or a mortgage with a stipulated time limit, after which the balance would be paid. Also, this note is taxable. So, the QI should hold it to defer capital gains tax. For instance, suppose the seller has a property worth $700,000 and you (the buyer) can afford only $500,000 in cash.

The buyer can propose seller financing, which means working with the QI to prepare and offer the seller a binding note that pledges the payment of the remaining $200,000. Once duly signed by the concerned parties, the QI will use the $500,000 cash and the note to buy the replacement property from the seller.

This strategy allows you to carry out the exchange smoothly without seeking external debt and still meet the IRS rules by keeping enough debt on the new property purchased. For real estate agents, this option offers more flexibility than conventional loans and also makes it easier to negotiate terms that work for each party. It’s more valuable when dealing with a tight timeline or high interest rates.

Using Rental Income

Rental income, also known as cash flow from the new property, is another good option to slowly pay off your mortgage. Instead of creating a taxable event by using the funds from the exchange to pay off the mortgage, you can leverage the replacement property’s monthly rental income to gradually cover the debt.

Delaware Statutory Trusts (DSTs)

A Delaware Statutory Trust (DST) is a strategy investors utilize to pool their money together and invest in real estate without having to oversee the property themselves. Rather than being active investors and owning a full property, investors own a small share of it, which gives them passive income from the property. 

A DST 1031 exchange helps with managing debt due to the ability of the DST to take on debt. This makes it easier for those who want to maintain their tax benefits but do not want to go through the stress of finding new loans. For investors doing a 1031 exchange and struggling to meet debt requirements, a DST is a great option.

Common Mistakes in 1031 Exchange with Mortgage Debt

Common Mistakes in 1031 Exchange with Mortgage Debt

In running a 1031 exchange with mortgage debt, it is very easy to fall into costly errors that easily attract IRS penalties and litigation. Let’s discuss some of these mistakes and how to avoid them.

Not Replacing Enough Debt

One common mistake people make during a 1031 exchange with debt is not replacing enough debt on the new property. When you add a lower mortgage, the IRS will calculate the difference in debts and make you pay taxes on it. To avoid this mistake, track your mortgage debts carefully and put at least the same amount of debt or more on the replacement property. 

Using Proceeds to Pay Off the Mortgage

If funds are taken from the exchange proceeds and are used to pay off the mortgage, the IRS will most likely consider this as tax-liable boot, which means taxes would be owed on that portion of gain. You can avoid this by leveraging other financing options, like rental income, to clear mortgage debt.

Failure to Follow IRS Deadlines and Rules

The 45-day identification period and the 180-day exchange period are two timelines that must be duly followed to avoid penalties. That’s why you should invest in proper planning before initiating an exchange. The crop of agents, brokers, and exchange facilitators you hire for the process also goes a long way in determining whether you will beat the deadline or not. Hence, work with professionals who are experienced in handling 1031 exchanges.

Not Hiring a Qualified Intermediary (QI)

This is the most important aspect of the exchange because without a QI, there can be no 1031 exchange. The QI is in charge of making sure that all IRS guidelines and deadlines are strictly adhered to. Thereby, preventing tax consequences and maintaining tax-deferral benefits. If you try to handle funds from the transaction directly without using the escrow services provided by a QI, you will disqualify the transaction.

Best Practices For Handling Mortgage Debt in 1031 Exchanges

Best Practices For Handling Mortgage Debt in 1031 Exchanges

Some of the best practices to bear in mind when handling mortgage debt in a 1031 exchange are: 

  • Ensure that the debt on the replacement properties has an equal or greater value than the debt on the investment property sold.
  • Avoid boot by carefully planning out the debt structure during the exchange.
  • Ensure your QI prepares proper and well-detailed documentation of the entire exchange to avoid future penalties.
  • Start searching for the replacement property before selling the old asset in order to beat the IRS identification deadline.
  • Keep accurate records of the debt amounts and receipts for every payment and exchange expense made.
  • Work with reputable and seasoned Qualified Intermediaries, tax advisors, exchange accommodation titleholders, real estate agents, and brokers. The more experience they have, the better your chances of getting a smooth deal.

FAQs

Can Seller Financing Help Pay Off My Mortgage in a 1031 Exchange?

Yes. If the seller of your replacement property agrees to offer financing, it can help you meet the IRS debt requirement without reducing your total cost.

What Are the Tax Implications of Using 1031 Proceeds to Pay Off a Mortgage?

Doing this creates a boot which the IRS views as taxable, and so you automatically owe capital gains tax, which defeats the purpose of a 1031 exchange.

How Does a 1031 Exchange Impact Refinancing?

Refinancing can only take place after the exchange is completed; doing it before or during the 1031 exchange can incur tax consequences.

Can You Do a 1031 Exchange if the Mortgage Balance Is Lower Than The Sale Price?

Yes, but you must either reinvest the entire sale price or use your own funds to make up for any shortfall in debt.

Is There a Limit on How Much Debt You Can Replace in a 1031?

No, there is no limit, but the debt must, of necessity, be equal to or greater than the debt on the relinquished property to fully defer tax.

Can I Use a 1031 Exchange to Pay Off My Mortgage?

Yes, you can. But doing so will trigger a taxable event.
