Yes. A 1031 exchange can involve a mortgage, but the key rule is that your replacement property generally needs to have equal or greater value and equal or greater debt than the property you sold, unless you add extra cash to offset the debt reduction.

Here are a few simple examples:

– **Example 1: Same or greater mortgage amount**
– You sell a rental property for $700,000 with a $400,000 mortgage.
– You buy a replacement rental for $800,000 and take on a $500,000 mortgage.
– Because you bought a higher-value property and replaced the debt with equal or greater debt, this structure may allow you to defer the full gain, assuming all other 1031 rules are met.

– **Example 2: Lower mortgage, but added cash**
– You sell a property for $700,000 with a $400,000 mortgage.
– You buy a replacement property for $700,000 but only take a $300,000 mortgage.
– That $100,000 debt reduction can create taxable “boot” unless you add $100,000 of additional cash into the purchase to make up for the lower loan amount.

– **Example 3: Trading up with financing**
– You sell a small rental for $500,000 with a $250,000 loan.
– You buy a larger rental for $900,000 using the sale proceeds plus a new mortgage.
– This is common because many investors use financing to trade into a larger property while keeping the exchange tax-deferred.

– **Example 4: Buying multiple replacement properties**
– You sell one rental property with a mortgage.
– You buy two smaller rentals as replacements and finance one or both.
– As long as the combined purchase price and debt replacement requirements are satisfied, this can work.

The mortgage itself is not a problem in a 1031 exchange. The important part is coordinating the sale proceeds, replacement loan, closing timelines, and qualified intermediary properly. You generally must identify replacement property within 45 days and close within 180 days.

A 1031 exchange lets you defer capital gains taxes when swapping one investment property for another “like-kind” property. When mortgages are involved, the key rule is that your new debt must be equal to or greater than the debt paid off on the property you sold—otherwise the difference is treated as taxable “mortgage boot.”

Here are common scenarios:

**Example 1: Equal Debt Replacement**
– You sell a rental with a $200,000 mortgage for $400,000
– You buy a replacement property for $500,000 with a new $250,000 mortgage
– Because your new debt exceeds the old debt, no mortgage boot is triggered

**Example 2: Trading Up**
– You sell a duplex for $600,000 (paying off a $150,000 loan)
– You purchase a small apartment building for $900,000 with a $400,000 mortgage
– All equity is reinvested and debt is increased—fully tax-deferred

**Example 3: Mortgage Boot (Taxable)**
– You sell a property with a $300,000 mortgage
– You buy a replacement with only a $200,000 mortgage
– The $100,000 debt reduction is taxable unless you offset it by adding $100,000 cash to the new deal

**Example 4: Cash Offset**
– Same as Example 3, but you bring $100,000 of your own cash to closing on the replacement
– Adding cash can offset a reduction in debt and preserve full tax deferral

**Key mortgage-related rules to remember:**
– You have 45 days to identify replacement properties and 180 days to close
– Funds must be held by a Qualified Intermediary—you can’t touch the sale proceeds
– Both properties must be held for investment or business use (not primary residences)
– The replacement loan must be in the same taxpayer/entity name as the relinquished property

Financing an exchange property can be trickier than a standard investment purchase because of the tight timelines. Lenders need to move quickly, and appraisal delays can jeopardize the 180-day window. Working with a lender familiar with 1031 timelines is critical.

Always confirm the tax treatment with a CPA or 1031 specialist before closing.

Yes, you can use a mortgage in a 1031 exchange. To fully defer capital gains taxes, you must acquire a replacement property of equal or greater value and replace any debt paid off on the old property with an equal or greater amount of new debt.

The key concept to understand is “mortgage boot.” If you pay off a mortgage on the property you sell (the relinquished property) but take on a smaller mortgage—or no mortgage at all—on the property you buy (the replacement property), the IRS considers that debt relief a taxable gain.

Here are two common examples of how a mortgage works in a 1031 exchange:

* **Example 1: Trading Up (Full Tax Deferral)**
You sell an investment property for $500,000 and pay off its remaining $200,000 mortgage. This leaves you with $300,000 in cash proceeds. To fully defer taxes, you must buy a new property worth at least $500,000 and take on a new mortgage of at least $200,000.

* **Sale (Relinquished Property):** $500,000
* **Mortgage Paid Off:** $200,000
* **Purchase (Replacement Property):** You buy a new property for $750,000.
* **Financing:** You use your $300,000 in proceeds as a down payment and take out a new mortgage for $450,000.

**Result:** Because the new property’s value ($750k) and the new mortgage ($450k) are both greater than the old ones, you have successfully deferred all capital gains taxes.

* **Example 2: Partial Deferral (Creating Mortgage Boot)**
Using the same sale, you sell your property for $500,000 and pay off the $200,000 mortgage. You find a replacement property for $600,000 but decide you want a smaller loan.

* **Sale (Relinquished Property):** $500,000
* **Mortgage Paid Off:** $200,000
* **Purchase (Replacement Property):** You buy a new property for $600,000.
* **Financing:** You take out a new mortgage for only $150,000.

**Result:** The difference between your old mortgage ($200k) and your new one ($150k) is $50,000. This $50,000 is considered “mortgage boot” and will be subject to capital gains tax. The rest of your gain remains deferred.
