How to Use a Line of Credit to Acquire Investment Properties

Can you use a home equity line of credit to buy rental properties? Yes, and for investors it can be one of the most powerful tools in the toolbox. A HELOC gives you daily access to the equity in your home or an investment property, lets you step into deals as a cash buyer, and can be reused again and again as you pay it down. Here is how a HELOC works, why investors keep one in their playbook, the exact math behind a property-every-three-years portfolio strategy, and the Texas home-equity rules that apply in 2026.

What Is a HELOC? Think of It Like a Giant Credit Card

A home equity line of credit, or HELOC, is a line of credit secured by real estate. Think of it like a giant credit card. It can be secured by your first home, your second home, or, in the example we use below, an investment property. You use it to make purchases, pay expenses, or consolidate debt, and it is tied to the equity you have built up in the property that secures it.

That description may sound simple, but the tool is incredibly dynamic. With a HELOC in place, you have daily, immediate access to the equity in your home or investment property. Imagine a free and clear home worth $500,000 that you have lived in for twenty years. If you want to access $80,000 to buy a car, or $200,000 to invest in a rental property, you would otherwise have to go through the motions of a brand new loan. With a HELOC already in place, you simply write a check. Immediate access to your home's equity is an enormous advantage by itself.

That daily liquidity also covers situations you cannot plan for. If an emergency hits and you need to write a check for $10,000 to a hospital, you can. If you want to cover a wedding for one of your children, you can write that check too, without going through a consumer loan application. You cannot call your existing lender after twenty years of payments and ask them to hand back $10,000 for a family hardship. They will not do it. A HELOC gives you access daily, for any reason, up to your limit.

Why Investors Use a Line of Credit

Here is where a HELOC becomes an investor tool. With that daily liquidity, you can acquire properties with the stroke of a pen, and you can bid for properties as a cash buyer. As an investor, cash is king.

Picture a bidding war on a $200,000 rental property. One buyer says they can pay the full price, but the deal will take 30 days to close because they are using a traditional loan. You say you can cut a check right now and close in five days, because you have cash. The seller goes with you, every time. Cash buyers can usually buy at a discount too. Sellers will often take less money when they know the deal closes right away, versus waiting a month for a slightly higher offer that could still fall apart.

There is another layer to this. I work with a lot of wholesalers, and wholesalers bring off-market deals. Those are properties that never hit the MLS, so the public never sees them on Zillow or Realtor.com. Wholesalers typically only work with cash purchasers. A HELOC gets you into that universe of off-market homes that few buyers ever know exists. Without a line of credit, or a wad of cash already in the bank, you simply do not have access to those inside deals.

How a HELOC Is Established

You qualify for a HELOC the way you qualify for any other loan. You apply with a mortgage loan officer or a bank, and the lender looks at your income, your debt-to-income ratio, your credit scores, and any existing assets that help your file. Fundamentally, they look at the value of the home relative to how much you want to draw.

Most states will allow you to loan up to 80 percent of the value of your home for a HELOC, and Texas applies the same 80 percent ceiling to home-equity debt on a homestead, though with different mechanics (more on that below). If you have a free and clear home worth $300,000, an 80 percent line would be $240,000. Because there is no underlying loan, that would be a first-lien HELOC.

In reality, most HELOCs sit in a second-lien position, meaning you already have an underlying loan on the home. Take that $300,000 home again, but this time with a $140,000 mortgage already in place. At 80 percent combined loan-to-value, you still have about $100,000 of available equity to draw as a second-lien HELOC. In the video, Patrick says that in Texas you are not allowed to do this, and that statement needs updating. Under current Texas law, a second-position home equity line behind an existing purchase-money first mortgage is not categorically prohibited. What matters is the 80 percent combined loan-to-value ceiling, the state's one-equity-loan-at-a-time rule, and the lender programs available today. The callout below spells out where the rules stand.

How the Line Works Day to Day

Once your HELOC is established, the functionality is the same whether it is a first-lien or a second-lien line. You have daily access to it, and you can literally cut checks against it. You pay interest only on the amount you have drawn, not on the full line. If you have a $200,000 line and write a $5,000 check, your interest accrues from day one on $5,000, not on $200,000.

Some lines have minimum draw amounts. A $500 minimum is commonly the starting point, though some lines set the minimum higher. Those details are typical, not universal; they vary by lender and program.

Paying the line down offers the same flexibility as drawing on it. You can pay down as much as you want, whenever you want. Say you owe $20,000 on a $200,000 line and get paid every two weeks. Throw $1,000 at it each paycheck and the balance drops to $19,000, so interest accrues on the lower number. You can keep paying it down, or you can expand the line again by drawing more, all the way back up to your limit.

A HELOC is typically established with a draw period of about 10 years, after which the line matures and moves into repayment. Terms vary by lender. Rates are commonly variable and often tied to a prime rate, which means your payment can rise when rates do. Treat all of these mechanics as general and lender-dependent, not universal rules.

One more qualification: a HELOC on a second home or investment property is far less standardized than a line on your primary residence. Investment-property lines typically carry higher credit requirements (often 700 or better), lower maximum loan-to-value, and are lender- and portfolio-specific. The specialty product Patrick references in the video, a HELOC on an investment property itself, exists, but it is a lender-specific program that few institutions offer. It is not a standard product you can assume every bank provides. If that specific tool interests you, ask about it directly when you shop the line.

The Worked Example: One Rental Property Every Three Years

Now for the part that makes a line of credit so compelling for an everyday investor. I work with plenty of investors who own 10, 20, or 30 properties, but this example is not about them. It is about someone earning a good salary, with $3,000 to $5,000 of cash flow over and above monthly expenses, who wants to buy a rental property every three or four years.

Understand why the line of credit is integral to the strategy. Without one in place, every property means re-qualifying for a new investment loan, which typically requires at least 25 percent down, a 30-plus day closing, and thousands of dollars in closing costs. In this example, that would be four separate financed transactions. Patrick estimates the closing costs alone would run roughly $30,000 across four loans, which is his illustrative estimate from the video; actual costs vary by lender, price, and market. With a HELOC, you establish the line once, then write a check at the end of each three-year cycle. No re-qualifying, no new closing costs, no hassles. That ease, convenience, and speed is exactly why serious investors put a line of credit in their toolbox from the start.

The Setup

First, you establish a $260,000 line of credit. That is the assumption everything else hangs on. You then buy a $200,000 rental home with cash from the line. In this area, a cash buyer can control a fairly decent $200,000 rental, one that pays about $1,800 a month in rent. You pay the line down $6,000 every month: the $1,800 in rent plus $4,200 out of savings and discretionary cash flow. At that pace, the line is back to zero after about three years.

Years 1 Through 3: The First Property

Year 4: The Second Property

At year four you buy another similar home, and the example assumes inflation has moved the price to about $220,000 with rent around $2,000 a month. You now have one free and clear house, worth over $200,000 (and more with inflation), throwing off $1,800 to $2,000 of rent with no mortgage on it. Your $6,000 monthly chunk is now $3,800 of rent across the two homes plus $2,200 out of your own excess cash flow.

Year 7: The Third Property

At the start of year seven you buy a third home, this time around $240,000 with rent near $2,200 a month. You now have two homes free and clear, which sounds impossible until you do the math. At this point the combined rent is roughly $6,000 a month, enough to cover the full paydown of the line, so you barely touch your own cash.

Year 10: The Fourth Property

At year ten you pick up a fourth property, this one bringing in about $2,400 a month in rent. You have three properties free and clear, and with the fourth in place your gross rent is roughly $8,400 a month. A line of credit, paid down continuously with rental income and a little discretionary cash flow, has turbocharged what is basically a retirement strategy. It puts you in an incredible position to step back from the day-to-day if you choose to. All because the line kept getting reused and repaid, then reused again.

Risks and What to Watch For

A line of credit is a tool, and every tool has edges. Keep these points in mind so the strategy works for you rather than against you.
