DSCR HELOC vs. HELOAN: How to Borrow Against a Rental Property

If you own a rental property with equity, you may be able to borrow against it without replacing your current mortgage. A DSCR home equity loan (HELOAN) gives you a lump sum of funds upfront, while a DSCR home equity line of credit (HELOC) lets you draw from a credit line over time.

Both home equity programs are typically second mortgages on the rental. That means you keep your existing first mortgage and take on a new payment. To see whether the rental can support that added debt, lenders look at the property’s debt service coverage ratio (DSCR), which measures whether the property’s monthly rent is enough to cover both loan payments and the property’s monthly housing costs. Lenders also look at the property’s value, your current mortgage balance, your credit, and other program requirements.

What is the difference between a DSCR HELOC and a DSCR HELOAN?

Your rental’s equity is its appraised value minus what you still owe on the property. A DSCR HELOC or HELOAN lets you borrow against some of that equity while keeping your current mortgage. The difference is how you receive the money and repay the new loan.

How a DSCR HELOC works

A DSCR HELOC lets you borrow against the equity in your rental property through a credit line. The lender sets a limit you can borrow, but you generally do not have to take it all at once. During the draw period, you can take money out, repay it, and borrow again up to your limit. You generally pay interest only on what you have borrowed. Some programs require you to take out a minimum amount at closing, so ask lenders if they have that requirement for their DSCR HELOC programs if you plan to leave the line unused.

When the draw period ends, you generally cannot borrow more from the HELOC. You enter the repayment period and begin paying off what you still owe. If you were paying only interest, your monthly payment may rise because you now have to repay the amount you borrowed, too. A variable interest rate can change that payment further.

Ask the lender to estimate your monthly payment during the draw period and after repayment begins, based on how much you expect to borrow. If the rate is variable, ask how those payments would change if the rate rises.

How a DSCR HELOAN works

A DSCR home equity loan (HELOAN) gives you the full loan amount at closing. You then repay it through monthly payments. If the loan has a fixed rate, the principal-and-interest payment on this second loan generally stays the same. Interest starts adding up on the full amount right away, even if you do not spend all the money immediately.

The amount you choose to borrow also affects whether the rental qualifies. A larger DSCR HELOAN generally means a larger monthly payment. The lender considers that payment alongside the cost of your existing mortgage, taxes, insurance, and any HOA dues when calculating DSCR. So even if you have plenty of equity, the property’s rent may limit the loan amount.

Both home equity options let you keep your existing first mortgage and its rate. You will have a payment on the new loan in addition to your first mortgage payment.

How much can you borrow with a DSCR HELOC or HELOAN?

Having equity in your rental does not mean you can borrow all of it. The lender checks how much debt it allows on the property and whether the rent can support your first mortgage plus the new HELOC or HELOAN. The smaller limit may determine how much you can borrow.

How much of your rental’s equity can you use?

Lenders use combined loan-to-value (CLTV) to compare the loans on your rental with its appraised value. They add what you owe on your first mortgage to the proposed HELOAN amount. For a HELOC, ask whether they use the full credit limit, even if you plan to draw less at first.

CLTV = (first-mortgage balance + HELOAN amount or HELOC limit) ÷ appraised value

Say your rental appraises for $500,000 and you owe $220,000 on the first mortgage. At a 70% CLTV limit, the lender would allow up to $350,000 in total loans on the property. Subtract the $220,000 you already owe, and that leaves room for a $130,000 HELOC or HELOAN. At an 80% limit, the room would be $180,000.

Those loan limits vary by product. For example, one lender, Griffin Funding, lists up to 70% CLTV for its DSCR HELOC and up to 80% for its DSCR HELOAN, depending on the borrower’s qualifications. The amounts above show what the property value could allow, before the lender checks rent and its other requirements.

Can the rent support both loans?

The lender also checks whether the rental’s monthly rent is enough to cover the payments after you add the HELOC or HELOAN. It considers your first mortgage payment, the proposed second-loan payment, property taxes, insurance, and any HOA dues. A DSCR of 1.00 means the rent used for the calculation exactly equals those monthly costs.

Estimated DSCR = monthly rent used by the lender ÷ total monthly housing costs with both loans

Suppose the lender uses $3,000 in monthly rent. Your first mortgage, taxes, insurance, and HOA dues total $1,700 a month. If a HELOAN adds $900 a month, the estimated DSCR is $3,000 ÷ $2,600 = 1.15. That would meet a program requiring 1.10 but fall short of one requiring 1.20.

For a HELOC, ask which payment the lender uses to calculate DSCR. It may differ from the interest-only payment you make during the draw period. Also, the $400 left after housing costs in this example is not necessarily profit; the rental still needs money for vacancies, repairs, and other expenses. Our guide to a good DSCR ratio explains that distinction.

What else could limit your HELOC or HELOAN?

The lender may also check your credit, how long you have owned the rental, its property type, its lease or market rent, and whether it is owned by an LLC. Programs can set minimum and maximum loan or credit-line amounts. If the property is vacant or used for short stays, check whether the specific program accepts it before relying on the equity and DSCR estimates above.

When should you choose a line instead of a lump sum?

A HELOC may fit when you cannot predict the exact timing or amount of a rental expense. You might draw for one renovation stage and borrow more later. Its flexibility comes with trade-offs: the rate and payment can move, the draw period ends, and the lender may require a minimum initial draw.

A HELOAN may fit when you know the amount and need it soon, such as for a specific renovation or another property's down payment. You get the full amount up front and, with a fixed-rate program, know the scheduled payment on the second loan. You also pay interest on that full amount from the start, even if some of it sits in your account.

Whichever home equity program you choose, test the rental's budget with both mortgage payments and money set aside for vacancies and repairs. A lender's minimum DSCR is an approval threshold, not a guarantee that the property will comfortably cover every expense.

Are DSCR HELOCs and HELOANs actually available?

Yes. Published programs include both revolving lines and lump-sum second mortgages. The examples below show why it is useful to compare the exact product and guidelines, not just the lender's name. Terms and availability can change.

The table shows how these published programs differ; it does not rank the lenders or guarantee you the listed terms. Program terms are subject to change.

Your credit, property, state, and requested loan amount may also change what is available. Deephaven and Angel Oak mainly publish their programs for mortgage professionals, so you may need a broker to get a quote. Ask each lender or broker to run the numbers for your rental and the specific HELOC or HELOAN you want, then compare the amount available, monthly payment, rate, and fees.

What should you compare before signing?

Request written, itemized quotes for the same amount so you can see what each choice would actually cost. Check:

• Payments now and later. Add the first mortgage and second mortgage. For a HELOC, ask what the payment would be if you used the full line, the rate rose, or the draw period ended.
• Total upfront costs. Compare origination, appraisal, title, and other closing fees, plus any required initial HELOC draw or ongoing line fee.
• Early payoff terms. A home equity loan may include a prepayment penalty, depending on the program. Ask whether a HELOC has any early-closure fee.
• Future refinance plans. Keeping your first mortgage today can be useful, but a second lien may complicate refinancing that first mortgage later. You may need the second lender's agreement or need to pay the second loan off.
• Risk to the property. Both loans use the rental as collateral. If you cannot keep up with the payments, you could lose it.

What about a DSCR cash-out refinance?

A DSCR cash-out refinance is another way to access rental equity, but it replaces the first mortgage rather than adding a second one. If keeping your current first loan matters, compare the HELOC and HELOAN first. If you are open to replacing it, request a cash-out quote too. Compare the cash you would receive after costs, the new monthly payment, and the total cost over the time you expect to keep each loan.
