What Is a First-Lien HELOC?
Quick Answer
A first-lien HELOC is a home equity line of credit that combines your existing mortgage with a traditional HELOC, making it the primary loan on your property.

A first-lien home equity line of credit (HELOC) is a type of home loan that combines a mortgage with a HELOC. It holds the first lien on your property, meaning the lender gets paid first in the event of foreclosure. Borrowers often choose first-lien HELOCs for their flexibility. However, these loans aren't without risks. A first-lien HELOC uses your home as collateral, so if you fail to make payments, you could lose your home.
Here's what you should know before choosing a first-lien HELOC.
What Is a First-Lien HELOC?
A first-lien HELOC is a line of credit that replaces your existing mortgage. HELOCs are normally second mortgages, occupying "second position" behind your primary, or "first position" mortgage. If you were to default on your home loans, the first-lien lender is first in line for any possible future debt repayment. A HELOC that replaces your existing mortgage moves into first-lien position.
Example: Say your home value is $500,000 and you still owe $200,000 on your mortgage. You could open a first-lien HELOC for $300,000, pay off your existing mortgage and still have $100,000 available to borrow from in the form of a credit line.
Many people choose first-lien HELOCs for their access to equity and initial interest-only payments. They're commonly used for expenses like home renovations, investments or debt consolidation.
While first-lien HELOCs can help you tap into home equity, they do have several drawbacks compared to keeping your traditional mortgage.
Tip: A second-lien HELOC is a more common type of HELOC that leaves your primary mortgage unchanged. It might be helpful to consider a first-lien HELOC as similar to a refinance and a second-lien HELOC as an additional funding source. The credit line and repayment of both types of HELOCs function the same.
Traditional Mortgage vs. First-Lien HELOC
While a first-lien HELOC serves as a revolving line of credit, a traditional mortgage is an installment loan with regular monthly payments over a set term. As such, traditional mortgages are best for borrowers seeking stability, while first-lien HELOCs may be ideal for those seeking greater access to their equity. Here's a quick breakdown of the two.
Traditional Mortgage | First-Lien HELOC | |
---|---|---|
Purpose | To buy a house | To access home equity |
Interest rate | Fixed or variable | Variable |
Term length | Up to 30 years | Up to 30 years |
Payment frequency | Monthly | Monthly |
Access to equity | No direct access | Revolving line of credit |
Risk | Lower, due to lower interest rates than a HELOC | Higher, due to variable interest rates and a revolving line of credit |
How Does a First-Lien HELOC Work?
A first-lien HELOC functions like a credit card, allowing you to borrow, repay and borrow again as needed. First-lien HELOCs typically consist of two phases: the draw period and the repayment period.
During the draw period, which typically lasts up to 10 years, you can borrow funds up to your credit limit and may be allowed to make interest-only payments on the balance.
After the draw period ends, the repayment period begins, during which you can no longer withdraw funds and must start repaying both your outstanding balance and interest. This period usually lasts 20 years.
A HELOC's interest is calculated daily based on your outstanding balance. For this reason, it's a smart idea to repay whatever you can during the draw period, even if you're not required to.
First-Lien HELOC Requirements
To get a first-lien HELOC, you generally need to meet requirements in the following areas:
- Credit score: You can typically qualify for a HELOC with a minimum credit score of 680, though exact requirements for first-lien HELOCs vary by lender.
- Debt-to-income ratio (DTI): DTI compares your monthly debt payments to your income. Lenders use it to determine whether you'll be able to manage an additional loan payment. Different lenders have different DTI requirements, but usually set a maximum between 35% and 45%.
- Income verification: For a first-lien HELOC, lenders look at your income to help determine whether or not you'll be able to make manageable, reliable payments.
- Loan-to-value (LTV) ratio: First-lien HELOCs commonly require an LTV ratio of 85% or lower, meaning the amount you borrow cannot exceed 85% of your home's appraised value.
First-Lien HELOC Pros and Cons
First-lien HELOCs offer some benefits, but there are downsides to consider as well. Here's what to know before taking the plunge:
Pros
-
Potentially favorable interest rates: If you have a high-interest existing mortgage, you may be able to get a first-lien HELOC at a lower rate.
-
Revolving credit flexibility: Among the most attractive features of first-lien HELOCs is their flexibility. You can borrow and repay a portion of your home equity as needed, much like a credit card.
-
Interest-only payments during draw period: During the draw period, you make interest-only payments, which may help with short-term liquidity.
Cons
-
Variable interest rates: Most HELOCs have variable interest rates, which could end up costing you more in the long run if rates rise.
-
Risk of foreclosure: If you fail to make payments on a first-lien HELOC, you could face foreclosure and lose your home.
-
Strong financial profile required: Lenders require good credit, stable income and strong equity for a first-lien HELOC, presenting possible roadblocks for those who are struggling financially.
-
Longer repayment period: If you put off paying your loan principal, you may experience a longer repayment period than you would've if you kept your original mortgage.
-
Closing costs: HELOC closing costs range from 2% to 5% of the amount you borrow, and they can add up if you require a large amount to pay off your original mortgage.
Should You Get a First-Lien HELOC?
Getting a first-lien HELOC can be risky if you're not on top of your finances. Keeping a traditional mortgage offers stability with predictable monthly payments, especially if it's a fixed-rate loan, allowing you to more easily budget over time.
Replacing your traditional mortgage with a first-lien HELOC introduces flexibility, but also risk. The ability to continually borrow up to your loan limit can lead to a cycle of ongoing debt if you're not careful. What's more, the variable interest rate means payments can increase unexpectedly, making it harder to manage your finances without strict budgeting.
That said, there are a few scenarios where it might make sense to replace your traditional mortgage with a first-lien HELOC:
- You have a high-interest first mortgage. If your first-lien HELOC rate is lower than the rate on your current mortgage, you could immediately start saving on interest.
- You're a financially disciplined borrower. First-lien HELOCs can be a great option for those who regularly budget and track spending.
- You plan on using your equity strategically. A first-lien HELOC can be a valuable tool for making smart investments and pursuing value-added projects like home improvements.
- You intend to pay off the loan quickly. The faster you pay off your loan, the quicker you can be debt-free.
How to Get a First-Lien HELOC
Getting a first-lien HELOC isn't as straightforward as applying for a traditional loan. To boost your chances of approval and secure favorable terms, it's important to take a strategic approach. Here are some tips to help you successfully obtain a first-lien HELOC:
- Look for specialized lenders. Not all banks and credit unions offer first-lien HELOCs. Specialized lenders may offer more competitive rates, flexible terms and streamlined approval processes.
- Improve your credit. Your credit score plays a major role in qualifying for a HELOC. It doesn't hurt to improve your score before applying.
- Create a payoff strategy. HELOCs are a revolving line of credit, and without a solid payoff strategy, it can be tempting to overspend and go deeper into debt.

Alternatives to a First-Lien HELOC
If you'd like to access your home equity but a first-lien HELOC doesn't seem like a good fit, there are a few alternatives you can consider:
- Cash-out refinance: A cash-out refinance replaces your existing mortgage with a new one, allowing you to tap into your home equity for a lump-sum cash payment. Cash-out refinances are sometimes used to consolidate debt and make home improvements.
- Home equity loan: Home equity loans are a type of second mortgage that allow you to borrow against your home equity and pay it back over time. Like cash-out refinances, home equity loans can be a good option for those seeking a large lump-sum payment.
- Personal loan: If you're looking to fund a one-time expense, consider getting a personal loan, which allows flexible borrowing and repayment options. Personal loans are often easier to get than HELOCs and may come with fewer fees.
- Reverse mortgage: If you're 62 or older, you may qualify for a reverse mortgage. A reverse mortgage uses your home's existing equity as collateral, and you won't have to pay it back as long as you live in your home.
