Refinancing a rental property isn’t just a financing decision, it’s a tax strategy. Lower interest rates, better cash flow, or a cash-out refinance can unlock new opportunities, but only if you understand how refinancing affects mortgage interest deductions, depreciation, and taxable rental income. Too many investors refinance blindly and miss deductions or worse, create tax issues they didn’t see coming.Here’s a clear breakdown of how refinancing really impacts your rental property deductions and how to stay compliant while maximizing returns.
Refinancing your rental property might seem like a no-brainer when interest rates drop, but it’s not just about getting a better mortgage deal or pulling cash out of your property. There are tax implications, and if you’re not careful, you might leave money on the table.
Let’s break down exactly how refinancing affects your rental property deductions, what stays deductible, what changes, and how to maximize the benefits while staying compliant.
The Basics: What is Refinancing?
Before we dig into the tax stuff, a quick refresher: refinancing means replacing your existing mortgage with a new one, often to snag a lower interest rate, reduce your monthly payment, or tap into equity (hello, cash-out refi). There are generally two types of refinancing:
-
Rate-and-term refinance – Adjusts your interest rate or loan term (but doesn’t pull out equity).
-
Cash-out refinance – You take out a new loan for more than you owe and pocket the difference.
Now, let’s get into how this affects your rental property deductions.
Can You Still Deduct Mortgage Interest?
Short answer: Yes, but with a twist. When you refinance, you’re essentially taking out a new loan. As long as the loan is used for the rental property (including improvements or paying off the old mortgage), the interest is still tax-deductible. However:
-
If it’s a rate-and-term refi, the new mortgage interest continues to be fully deductible.
-
If it’s a cash-out refi, you need to track how the funds are used. Only the portion used for the rental property is deductible.
Example:
If you pull $50,000 cash out and use $30,000 for renovating the rental and $20,000 for personal debt, you can only deduct the interest on the $30,000.
So, keep your paperwork tight and earmark those funds clearly.
What Happens to Depreciation?
Here’s where it gets interesting. Refinancing doesn’t restart your depreciation schedule.
Depreciation for rental properties is based on the original purchase price (minus land value), not your mortgage balance or refinancing amount.
That means:
Refinancing has zero impact on your property’s depreciation schedule. Whether you refinance once or five times, your annual depreciation deduction chugs along untouched (usually over 27.5 years for residential rental properties in the U.S.).
What About Closing Costs on the New Loan?
Refinancing comes with some fees, and some are deductible. Here’s how it breaks down and which costs are not deductible:
-
Appraisal fees
-
Title fees
-
Legal fees
-
Credit report fees
These are considered capital expenses. You can’t deduct them in the year you refinance, but you may be able to amortize them (spread out and deduct over the life of the loan).
Always double-check with your tax pro to see what can be amortized or deducted.
Using Cash-Out Funds for Other Investments
Let’s say you pull equity from Rental Property A and use it as a down payment for Rental Property B. Can you deduct the interest on that portion? Yep! The key is “tracing the funds.” As long as the cash is used for another income-producing property, the IRS allows you to deduct the corresponding mortgage interest. So, if you’re leveraging one property to grow your portfolio, good news: you might still be in deduction territory.
How Refinancing Impacts Your Cash Flow and Taxable Income
Refinancing can lower your monthly payments, which is awesome for cash flow. But watch out, it could also affect your taxable income.
Here’s why:
-
Lower interest = lower deduction.
-
Lower payments = more net rental income = potentially higher taxable income.
So while your bank account might feel fuller month-to-month, your tax bill could go up a bit. It’s a good problem to have, but it’s still a problem if you’re not prepared.
Pro Tips to Maximize Tax Benefits
Here’s how to stay smart and legal:
-
Track everything. Especially if you’re doing a cash-out refinance. Keep receipts, bank statements, and documents showing how the funds were used.
-
Use funds wisely. To keep mortgage interest fully deductible, use the money for property improvements, maintenance, or to acquire another rental—not for personal expenses.
-
Talk to a tax pro. Every situation is unique, and rental real estate tax rules can get tricky. A tax expert can help you squeeze out every legal deduction and keep you audit-proof.
-
Amortize costs correctly. Closing costs might not be deductible upfront, but many can be spread over the loan’s life. Don’t leave that money on the table.
What Happens If You Refinance More Than Once?
No worries. You can refinance multiple times. Each new loan is treated as a separate event. The key is to apply the same logic every time:
-
Is the new loan being used to support the rental property?
-
Are you keeping clean documentation?
-
Are you correctly allocating and deducting interest?
-
As long as the funds remain tied to the income-producing asset, your deductions are generally safe.
What About Passive Activity Loss Rules?
If you’re a small-scale landlord, there’s one more IRS curveball to keep in mind: Passive Activity Loss (PAL) limits. Refinancing won’t directly affect these limits, but if your improved cash flow from a refi increases your net rental income, it could influence whether or not you can deduct rental losses against other income. Typically:
-
If your adjusted gross income (AGI) is under $100,000, you can deduct up to $25,000 in rental losses.
-
The deduction phases out completely by the time your AGI hits $150,000.
So, a refinance that makes your rental more profitable might reduce your passive loss deduction eligibility. Just another reason to get strategic with timing and planning.
FAQs
Can I deduct interest on a cash-out refinance if I use the funds for home improvements?
Yes, but only if the improvements are made to the rental property. Using the funds for your personal residence disqualifies that interest from being deductible.
Does refinancing reset my depreciation schedule?
Nope! Depreciation is based on the original cost of the building, not the current loan balance or refinance amount.
Are refinancing closing costs deductible?
Most aren’t deductible right away, but some may be amortized over the life of the loan, especially if they’re directly related to obtaining the mortgage.
What if I refinance and pull cash to buy another rental?
Good news! Interest on the portion of the loan used to buy another rental property is generally deductible, as long as the funds are clearly traced and documented.
The Bottom Line on Refinancing and Rental Deductions
Refinancing a rental property can be a smart move, whether you’re slashing interest rates, improving cash flow, or scaling up your real estate game. And yes, the tax perks are still there as long as you play by the rules.
To recap :
-
Mortgage interest stays deductible but only for the rental-use portion of the loan.
-
Depreciation doesn’t change.
-
Closing costs can’t be deducted upfront but may be amortized.
-
Proper documentation is critical, especially with cash-out refis.
