Should I Use a Margin Loan to Buy a Home?
When you’re ready to purchase a home, traditional financing options like mortgages typically come to mind. But for individuals with substantial investment portfolios, an alternative exists: using funds drawn on a margin loan to buy a home.
Financing a home purchase with a margin loan is technically a “cash buyer” strategy. It can offer unique advantages, but it also comes with significant risks.
Before exploring whether this strategy makes sense for your situation, it’s important to understand how margin loans work. You should also know what advantages they might offer and how their potential drawbacks could affect your financial health.
How Margin Loans Work
Margin loans are a bit more complicated than your average mortgage or personal loan, so we turned to an expert for help. I asked one of my colleagues to speak with a Registered Investment Advisor (RIA) at a major financial services company to get the facts.
Here’s what we learned, in four parts:
1. A Margin Loan’s Interest Rate Changes Over Time
Margin loans have a “floating interest rate,” which means the interest rate changes over time.
Hopefully, you’ve at least skimmed our article on adjustable-rate mortgages (ARMs). If you have, you should already know that changing interest rates always translates to additional risk for the borrower.
The interest you pay on a margin loan is calculated and charged daily, but the total will be charged to your account monthly. In this type of loan, the rate is set relative to the current federal funds rate (which is variable), plus a margin measured by basis points (think of the margin as a layer of fat that sits on top of the rate).
Most people don’t encounter these two concepts often, if at all, so let’s break them down as well:
Federal Funds Rate
The federal funds rate is the benchmark interest rate that U.S. banks charge one another for overnight loans. A target range of this rate is set by the Federal Reserve’s Federal Open Market Committee (FOMC) to do things like control inflation.
The target range was lowered to 3.75–4.00% in October 2025, which is its current position as I write this article. That could change, however.
Basis Points (bps) and Margin
Sometimes referred to as “bps” (or playfully as “bips”), basis points are units that measure any change in an interest rate or the difference between a base interest rate and a “final” or “real” interest rate. One basis point is equivalent to 1/100th of 1% or 0.001%.
For example, if an interest rate shifts from 4.00% to 4.25%, it has risen by 25 basis points, or 25 bps.
With a margin loan, your lender may add a “margin” measured by basis points to the federal funds rate. Together, these determine your loan’s real interest rate. That margin may be calculated by several factors, including your creditworthiness and a general risk assessment conducted by the lender.
The margin is typically fixed in a margin loan. While changes in the federal funds rate could change your loan’s real interest rate over time, the basis points your lender added as a margin won’t typically change for the lifetime of the loan.
Example of a Margin Loan’s Interest Rate
Here’s an example. Let’s imagine that the current federal funds rate is 4.00% and your lender decides to add 200 basis points as a margin to your loan.
Since one basis point is 1/100th of 1%, 200 basis points are equal to 2.00%.
Therefore, the real interest rate of your margin loan is 6.00%.
Or, more accurately, it starts at 6.00%.
If the Fed decides to increase the target range of the federal funds rate to 4.50%, you could see an increase of up to .50% (50 basis points) in your interest rate due to the variable.
You could also see a drop in your loan rate. During the COVID-19 pandemic, the Federal Reserve lowered the federal funds rate to a range of 0%–0.25%, one of the lowest ranges in history. In essence it was free money since the rate of inflation on assets was skyrocketing at the same time.
However, another extreme occurred in 1981. That year, the federal funds rate at times reached ranges over 19% to combat inflation. The annual average for that year was 16.39%, the highest on record. My clients, up one generation from me, remind me of these startling rates when we have conversations about rates currently in the 6’s.
2. Your Loan Amount Limit is Based on Your Held Collateral
How much you can borrow as part of a margin loan is based on the amount of collateral you have invested. For example, if you have funds invested in a portfolio through Fidelity Investments, Charles Schwab, or even a FinTech like Robinhood, you may also be able to access a margin loan through them.
According to the RIA we spoke with, an individual can borrow 70-80% of the amount they hold in bonds and 50% of the amount held in equities at the financial firm they work with. Other lenders may have different policies for margin loan limits.
3. A Loss in Collateral Value Could Trigger a “Margin Call”
A “margin call” on a margin loan is a demand from your broker to deposit additional cash or securities into your account. Your broker will demand it because the value of your collateral has fallen below the required maintenance level for the loan. Margin Call is also the name of a scary movie, one that will probably come back into popularity in as soon as most people seem to forget the 2008 Financial Collapse.
This can happen when the value of the assets you bought with borrowed funds drops, reducing your equity as a percentage of the total account value below the firm’s minimum requirement. If you don’t meet the margin call, the broker may sell some of your holdings to restore your account to the required level.
This is a nasty scenario, but it’s still not the worst-case scenario.
4. You’re Liable for the “Full Recourse” of the Loan
A margin loan is a “full recourse” loan. That means you, as an individual, are liable for full repayment.
This brings us to the worst-case scenario. Since your collateral is made up of investments, those investments can lose value due to shifts in the market. They could even lose so much value that you can’t cover your loan balance even if you liquidate everything.
If that happens and your lender demands repayment of the loan, you’ll have to find another way to pay for it.
The Pros: Why You Might Use a Margin Loan to Buy a Home
You may already be able to tell that using a margin loan to buy real estate is riskier than taking out a standard mortgage. Markets can be volatile, and a margin loan’s interest is variable, whereas a fixed-rate mortgage is consistent throughout its entire lifespan.
That said, there are some advantages to consider.
1. Immediate Access to Capital Without Liquidating Investments
One of the primary advantages of using a margin loan to purchase a home is the ability to access substantial capital quickly without needing to sell your existing investments. This can be particularly attractive if your portfolio is positioned in a way that you believe will generate strong returns over the coming years.
Instead of selling appreciated assets and triggering capital gains taxes, you can borrow against them and keep those investments intact.
2. Potential for Tax-Efficient Positioning
For investors who are strategic about their portfolio management, a margin loan can offer tax advantages. By borrowing against your investments rather than selling them, you avoid triggering capital gains taxes in the year of purchase.
The interest you pay on a margin loan may also be tax-deductible in certain circumstances. This depends on how the funds are used and your specific tax situation.
(It’s important to consult with a tax professional about whether your situation qualifies for such deductions.)
3. Flexibility in Repayment Structure
Unlike a traditional mortgage, which has a fixed amortization schedule and repayment timeline, a margin loan offers more flexibility. You can potentially pay down the loan faster without penalty.
You could even structure your repayment around other financial goals and cash flow events in your life.
4. Becoming a Cash Buyer
Using margin loan funds to purchase a home outright makes you a cash buyer, which can provide negotiating leverage in competitive real estate markets. Cash offers are often viewed favorably by sellers because they eliminate financing contingencies and can close more quickly.
In some cases, making a cash offer may even allow you to negotiate more favorable purchase terms.
5. No Mortgage Pre-Approval Process
Since you’re not seeking traditional mortgage financing, you avoid the lengthy pre-approval and underwriting process associated with conventional home loans. This can simplify and accelerate the home purchase process.
6. The Interest Rate May Be More Favorable Than Your Alternatives
Depending on market conditions and your creditworthiness, the interest rate on a margin loan might be lower than other forms of debt you could access. If the federal funds rate is low and the broker’s margin is competitive, your all-in borrowing cost could compare favorably to mortgage rates.
If you’re buying at a time when mortgage rates are elevated, it might make a margin loan more attractive.
7. You Have a Future Refinance Strategy
For those who have a clear financial plan, using a margin loan to purchase a home can be part of a broader wealth management strategy. The expectation may be to use a cash-out refinance on the newly purchased property at a future date to pay off the margin loan.
This combines the advantages of being a cash buyer now with the ability to tap home equity later.
8. If you DO use a Margin Loan to buy real estate don’t forget THIS irreversible potential mistake …
The future sale price of the home you are about to buy is contingent upon one thing: Free and Clear title.
We already agreed that when you buy a house with a margin loan, you become a Cash Buyer. A Cash Buyer circumvents the quality control that a mortgage underwriter would put upon the mortgage application.
This may be a good thing as it relates to your personal finances such as: tax returns, bank statements and accounting reports. But as it relates to the property (the collateral of a mortgage) you circumvent the need for a title search + rundown and title insurance.
Buying a home without a title rundown holds you responsible for all the undischarged prior liens on the property. This is basic Real Estate 101 knowledge. No buyer wouldn’t do this step.
But where I’ve seen our very experienced buyers go wrong is electing to NOT purchase Owner’s Title Insurance. Owners Title Insurance can only be acquired at the time you purchase the property.
Like Life Insurance, you can’t go back later and buy it once you realize you have a health issue, or in the case of your home, you see a flaw in the title.
That flaw could be costly (or impossible) to remedy.
An unremedied title flaw, can, check that, will put the value of your future sale price to ZERO (you can’t sell what you don’t technically own).
TAKE AWAY: Owners Title Insurance:
Don’t leave (your) home (closing) without it.
The Cons: Why You Might Want to Think Twice About Using a Margin Loan to Buy a Home
Imagine someone with a significant, stable investment portfolio who wants quick access to liquidity without having to sell assets, and who fully understands (and is willing to take on) the risks of margin borrowing because they know they could still recover, stay afloat, or even thrive if the loan goes south.
We think that’s a pretty good description of who should consider buying a home with a margin loan. That is not, however, a description that applies to most homebuyers.
Here are the reasons you may want to avoid using a margin loan to buy a home.
1. Variable Interest Rates Always Create Risk
This is perhaps the most significant drawback: margin loans carry floating interest rates. Unlike a fixed-rate mortgage, where you know your exact monthly payment for 15, 20, or 30 years, a margin loan’s interest rate is tied to the federal funds rate, which fluctuates based on Federal Reserve decisions and economic conditions.
If the federal funds rate rises significantly, your monthly borrowing costs could increase dramatically. This uncertainty makes long-term financial planning more difficult and could strain your cash flow if rates spike unexpectedly.
2. Margin Calls Can Force Unfavorable Asset Sales
If the value of your investment portfolio declines, you could face a margin call. This means your broker will demand that you either deposit additional cash or securities into your account or allow them to automatically sell portions of your holdings to maintain the required collateral level.
This creates a particularly problematic scenario: You’ll be forced to sell investments at depressed prices when markets are down, and you likely don’t want to sell. This can lock in losses and disrupt your long-term investment strategy at exactly the wrong moment.
3. Full Recourse Liability Creates Personal Risk
Because margin loans are full recourse, you’re personally liable for the entire loan amount.
Consider a worst-case scenario: You use a margin loan to buy a $500,000 home, putting down 50% of your investment portfolio ($250,000) as collateral. Your portfolio then suffers a significant decline.
A margin call forces the broker to sell your investments at depressed values. The proceeds aren’t enough to cover the margin loan.
Now, you must come up with cash to cover the shortfall in addition to being liable for your home purchase.
4. Market Decline Affects Both Your Home and Collateral
Using your investment portfolio as collateral to buy a home creates a problematic concentration of risk.
If a major market downturn occurs, you face a “double hit.” Not only does your collateral lose value, but the value of your home could also decrease if the real estate market softens.
This means your two largest assets are exposed to correlated risks rather than being appropriately diversified sources of value.
5. A Margin Loan’s Interest May Be Higher
While margin loan rates might sometimes be competitive with mortgage rates, this isn’t guaranteed. If the federal funds rate rises or if the broker’s margin is high, your all-in borrowing cost could exceed what you’d pay for a traditional mortgage.
Over the life of the loan, these higher interest rates can cost substantially more in total interest paid.
6. You Lose the Tax Benefits of the Traditional Mortgage Interest Deduction
A traditional mortgage on a primary residence allows you to deduct mortgage interest from your federal income taxes (up to certain limits). While margin loan interest might be deductible in some circumstances, the rules are complex and depend on how the funds are used.
You could lose valuable tax deductions by not using a traditional mortgage.
7. A Margin Loan Can Disrupt Your Long-Term Investment Strategy
Using a margin loan essentially redirects capital from your long-term investment portfolio into real estate. If your investment portfolio was generating strong returns or was positioned to do so, extracting capital via a margin loan changes your asset allocation and could interfere with your wealth-building strategy.
8. There’s Uncertainty Around Timing a Refinance
A common strategy for margin loan home buyers is to refinance the property with a traditional mortgage after purchase, using the home equity to pay off the margin loan. However, refinancing isn’t guaranteed.
If property values decline, if your credit situation changes, or if lending conditions tighten, you might not be able to refinance on favorable terms—or at all.
If you’re unable to refinance as planned, you’re stuck servicing the margin loan, with all its interest rate volatility and margin call risks, indefinitely.
9. You’ll Need to Monitor and Manage Your Margin Loan
Margin loans require active management. You need to monitor interest rate movements, your portfolio’s collateral value, and margin call requirements. This isn’t a “set it and forget it” borrowing situation like a traditional fixed-rate mortgage.
10. It Could Create Tension Between Your Home Ownership and Investment Goals
Using your investment portfolio as collateral means you can’t fully leverage those investments for other opportunities. If an attractive investment opportunity arises, you may be constrained by the fact that a portion of your portfolio is tied up as collateral for your home purchase.
Similarly, rebalancing your portfolio becomes more complicated when a portion is serving double duty as collateral.
The Bottom Line: Buying with a Margin Loan is Risky for Most Homebuyers
Using a margin loan to purchase a home could be an effective strategy for the right person in the right circumstances. However, that person is typically an investor with substantial assets, high risk tolerance, a clear financial plan, and confidence in their ability to manage the complexities involved in this strategy.
For most homebuyers, the risks outweigh the benefits.
At GoldCoast Mortgage, we treat financing and buying a home holistically. It’s a financial decision, but it’s also an important step in our clients’ lives.
We believe every aspect of the mortgage experience should support our clients’ life goals, not just their financial goals.
For example, a couple with a baby on the way typically wants to focus on creating a supportive environment for their growing family. They don’t want to worry about whether collateral depreciation might trigger a margin call on their loan and throw their financial plans into disarray.
