How to build passive income with real estate assets

Dreaming of earning regular money from a source that doesn't require daily effort or active participation? Real estate offers one of the most reliable paths to passive income. Many opt to purchase a rental property or go the Airbnb route. Problem is, these strategies almost always require capital to get started. But if you own a home, you may already have that capital in the form of home equity sitting idle, which could be used as the seed capital for any real estate investment route. And a home equity line of credit (HELOC) or home equity loan is often the most efficient way to tap your home equity.

Remember: How you fund your first real estate investment step matters as much as which path you ultimately choose. Read on to learn more about passive income real estate options like a HELOC.

The main paths to passive income through real estate

Truth is, there are several routes you can take to generate passive income via real estate. Let's explore each of the following:

• Rental property. Purchasing a rental property and leasing it to tenants is often the clearest path because it creates recurring income through long-term leases, and its strengths are predictability, leverage, and the possibility of appreciation. "The upside is steady monthly income and the property gaining value over time, but it's not actually passive because you are dealing with maintenance, vacancies, tenant issues, and property taxes," says Brennan Kolar, founder of Atlas CPA Index.

• Short-term rentals. Leasing out a property short-term via Airbnb, VRBO, or another platform can produce higher gross income in the right market. But short-term rentals tend to be far less passive because they involve pricing changes, cleaning, platform dependence, and local regulatory risk. "The management burden is heavier with this option, and local regulations are getting tighter in many markets," cautions personal finance expert Andrew Lokenauth.

• House hacking. If you purchase a multi-unit property and live in one unit while renting out the others, you can benefit from a lower barrier to entry. "House hacking is one of the most efficient starting points because it lets you reduce housing costs while building rental income from the same asset. However, it requires a higher tolerance for shared space and less privacy," says Dennis Shirshikov, a professor of finance and economics at City University of New York/Queens College.

• Real estate investment trusts (REITs). REITs are your most passive option operationally because you purchase shares rather than manage property. "Here, you buy shares the same way you would buy a stock. The trust pays you a portion of the rent it collects on the properties it owns, and you can sell any time," Kolar notes. But the trade-off is reduced control, market volatility, and less ability to force value through operational improvements.

• Using your existing equity. This option, which involves tapping your equity using a HELOC or home equity loan, is commonly the most overlooked. The advantage here is straightforward: If you have accrued equity in your current home, you can access and deploy it toward one of the above options, but without selling your home. "It's attractive because it turns dormant balance-sheet value into investable capital," Shirshikov continues. "But the advantage of easy access to your equity must also be weighed against the reality that your home itself becomes tied more directly to the success of the investment strategy."

Why equity is often the overlooked starting point

Many passive income experts will tell you to jump straight into a rental property purchase without addressing the question of funding. But for a homeowner with equity, a HELOC or home equity loan could be the lowest-cost, most accessible means of raising the cash needed.

Most homeowners don't realize that they are sitting on a pile of investable capital locked inside their residences. A HELOC allows you to access that equity easily as a revolving line of credit, secured by your home, and it usually charges much lower interest rates than credit cards or personal loans. You draw only what you need, and you pay interest on what you borrowed during the draw period.

"The average homeowner with a mortgage today has around $300,000 in home equity, which is the difference between what the home is worth and what they still owe. This means you can typically borrow against 80% to 85% of that amount using a HELOC, which, in this example, means $240,000 to $255,000 they can access without selling, replacing their current mortgage, or needing cash in the bank," explains Kolar. "The average HELOC rate right now is around 7% to 7.5% (at time of publication), and fees to open a HELOC often run lower compared to pursuing a cash-out refinance for the same amount of money. For homeowners who own their home outright or nearly outright and have a steady paycheck but no large savings account, a HELOC gives them access to money they couldn't get any other way at that rate."

Better allows qualified borrowers to borrow up to 90% of their home's value on a HELOC — higher than the 80–85% cap most lenders impose. And with the One Day HELOC, qualifying customers can get a decision in 24 hours and cash in as little as 7 days¹.

How to use a HELOC for real estate investing — practically

Here's how a HELOC strategy to generate passive real estate income would work. Let's say your home is worth around $400,000, and you owe roughly $200,000 on your mortgage loan. That means you have accrued about $200,000 in equity. Most lenders will allow you to borrow up to 80% to 85% of your property's value, minus what you owe. In this example, you can pursue a usable HELOC of around $100,000–$120,000.

"Next, imagine you apply $100,000 from that HELOC as a down payment on a rental property worth around $300,000, which means you would need to take out a separate mortgage for the remaining $200,000," says Lokenauth. "If that rental generates about $2,000 per month in rent, and your total expenses — mortgage, taxes, insurance, and maintenance — run approximately $1,400 per month, you will net roughly $600 per month in passive income. Keep in mind that your HELOC interest at current rates might cost around $500 per month. But that's still positive cash flow — plus, you are building equity in two different properties at once. Over time, as you pay down both loans, your cash flow will get even better."

Example is for illustrative purposes only. Rates, payments, and total interest will vary based on credit profile, loan terms, and market conditions.

Of course, your results can vary, and tapping your home equity and investing in real estate come with real risks, which we will cover next.

The risks

It's easy to focus on the benefits of tapping equity to generate passive income via real estate. But it's equally important to understand the drawbacks, too.

"The central risk is that you are leveraging one property to purchase another. This creates two layers of exposure instead of one," adds Shirshikov. "If your rental underperforms, your HELOC still has to be paid."

Luke Babich, CEO of Clever Real Estate, agrees.

"Don't forget that you'll also need to continue paying property taxes, insurance, and maintenance. Without a strong emergency fund separate from your HELOC buffer, you can get squeezed fast," he says. "Additionally, your equity is only accessible if you stop drawing on it; if you've maxed out your credit line, you are exposed."

Also, real estate investing is not truly "passive" at the beginning: there's work required to find the right property, finance it, and manage it. And cash flow isn't guaranteed. Vacancies, repairs, and rising expenses can eat into your passive income. Lastly, keep in mind that HELOC rates are variable, which means your borrowing costs can change over time.

Is this right for you?

Ask Kolar and he'll tell you that the best candidates for using a HELOC to produce passive real estate income are homeowners with at least 30% to 40% equity positions, stable income from a job or business that can cover the HELOC payment if the rental sits empty, and enough cash set aside to handle a few months of vacancy or unexpected repairs without falling behind on either payment.

"You need to run the numbers carefully. If your property is vacant two months out of 12, you need to see if you can still cover everything before committing," he continues.

Babich adds that you should also "have the temperament to handle tenant issues and market downturns, and be comfortable with managing the real estate yourself or be willing to hire a property manager."

If you meet those thresholds and want to understand exactly how much equity you can access, Better's fully online HELOC application lets you check your rate and borrowing capacity without a branch visit or a credit impact. Many borrowers complete the initial application in under three minutes.

FAQs

I own a home, but I don't have cash savings. Can I still invest in real estate for passive income?

Yes — if you have equity, a HELOC can be a funding source. Owning a home with equity can open a path to investing even when liquid savings are limited because the equity can function as a source of capital via a HELOC or home equity loan. But you need to have enough buffer in reserves for vacancies, repairs, rate increases, or delayed rent. This strategy requires careful planning because your home serves as collateral for the loan or line of credit.

Is a HELOC a good way to fund a rental property purchase?

A HELOC can be a smart way to fund a rental property purchase if it is used strategically, especially for the down payment, closing expenses, or light rehabilitation. Its major strength is flexibility, because you can draw only what is needed rather than replacing the entire first mortgage on your primary residence. Just remember that the funding source itself comes with variable rates and is secured by your home. That means the rental needs to be strong enough to justify that added layer of obligation.

How much equity do I need to open a HELOC for real estate investing?

The exact amount will depend on your chosen lender, but many lenders prefer a combined loan-to-value ratio of 80% to 85%, which means having 15% to 20% equity remaining after you draw on the line of credit. Better allows qualified borrowers to access up to 90% of their home's value — higher than what most lenders offer. Your available equity is determined not only by your home's value but by the lender's cap, your income, and your credit profile.

What's the difference between using a HELOC vs. a cash-out refinance to fund an investment?

A HELOC is a revolving line of credit layered on top of your existing mortgage. A cash-out refinance replaces your current mortgage with a new, larger loan and lets you pocket cash from the difference. A HELOC is often better for flexibility because you can borrow in stages and leave your original first mortgage untouched, which is particularly appealing if your existing mortgage loan has a favorable lower rate. A cash-out refi can be a better option if you want long-term fixed-rate financing and a single payment structure. However, it resets your entire mortgage at a new rate and can increase your borrowing costs across the full loan balance — not just the amount you need for investing. The choice between a HELOC versus a cash-out refinance often comes down to whether you value flexibility more or payment certainty more.

Are rental income and REITs equally passive?

REITs are more passive because you do not manage tenants, coordinate repairs, or resolve operational issues when you invest in a REIT. Rental income can become relatively passive only after your property is stabilized and professional management is in place. But you remain exposed to leasing decisions, capital expenditures, legal obligations, and market-specific disruptions.

Can I use a HELOC on my primary home to buy an investment property?

Yes, you can use a HELOC on your primary residence to purchase an investment property. You can draw against your equity in the primary residence and use those funds for your down payment, acquisition costs, or improvement expenses on an investment property. The transaction is legally and financially possible in many cases, but you need to determine whether the projected rental income and your financial reserves will be sufficient.

What happens to my HELOC if the rental property doesn't provide the necessary cash flow?

You're still responsible for HELOC payments regardless of rental income. If your rental property doesn't generate enough cash flow, you must cover the gap from salary, savings, or other income sources. Because your HELOC is tied to your credit and home equity, weak rental performance can become a household-level financial problem quickly. This is why prudent investors maintain sufficient cash reserves and avoid structuring deals that only work under ideal assumptions. Be sure to carefully model cash flow before committing.

The bottom line

Building passive income through real estate is a marathon, not a sprint. But if you have sufficient equity, the starting line could be closer than you think if you are willing to pursue a HELOC.

"Home equity remains one of the most underused assets in America, sitting idle in millions of homes right now," says Lokenauth. "Take the time to learn your equity position, crunch your numbers, and explore the possibilities while also reckoning with the possible downsides."

Better's HELOC is fully online, with no branch visits required and decisions available in as little as 24 hours for qualifying borrowers. If you're ready to understand what your equity could make possible, the first step takes as little as three minutes.

Home equity products are subject to credit approval and property eligibility. Borrowing against your home equity puts your home at risk as collateral.
