How Much Can You Borrow on an Investment Property HELOC to Pay Off a Private Loan?

The Quick Read: It depends on three numbers: the property’s value, the lender’s combined loan-to-value cap, and every other lien that stays on the title. The line can be no larger than value times that cap, minus those liens, and the private loan payoff (including accrued interest and fees) has to fit inside that room. CLTV counts all debt on the property against its value.

• The formula: maximum line = value × the lender’s CLTV cap − liens that remain.
• The payoff is not extra: it comes out of the new line, so it must fit inside the same ceiling.
• Rentals get less: investment-property lines carry lower caps and a smaller lender pool than lines on a primary home.
• Your profile decides next: a HELOC is underwritten mainly on you, not on the rent, so entity title and income documentation can shrink or block the line.
• The fallback: when the payoff outgrows the room, a DSCR cash-out refinance sizes on the property’s rent and a 75% LTV ceiling on standard rentals, subject to lender guidelines.

How Do Lenders Size the Maximum Line?

Lenders take the property’s appraised value, multiply it by their CLTV cap, and subtract the debt that stays. What remains is the most the line can be. Nothing in that math changes because the money is going to a private lender.

Nasdaq’s explainer on HELOC requirements calls CLTV the key ratio in qualifying. That matches how the files look from a broker’s desk. The cap is the first number to learn, because everything else is arithmetic after it.

Rentals get a lower cap than a primary home does. NerdWallet’s guide to HELOCs on investment properties says the lender pool is smaller and the limits are lower than on a primary residence. Those are market figures for equity lines, not network figures.

For comparison, DSCR cash-out refinances placed through select lenders in Lendmire’s wholesale network top out at 75% LTV on a standard rental. Short-term-rental collateral tops out at 70% on a cash-out. Those are program ceilings, subject to lender guidelines.

Lenders usually count the full credit limit in the CLTV test, not only what you draw. A line sized to the payoff counts in full from day one. Many lenders also apply a dollar cap on rental lines, and a valuable, lightly mortgaged property can hit that cap before it hits the percentage cap.

A Worked Example in Percentages

Take a rental valued at $400,000. Assume a lender cap of 70% CLTV. That cap is a modeled assumption for illustration, not a quote or a network figure.

In scenario A, the payoff sits well inside the cap. The 12 points of spare room matter because the payoff includes interest through the closing date, plus fees. The line also has to cover closing costs.

In scenario B, a first mortgage stays and the private loan sits behind it. The room shrinks to 45% of value, but the payoff needs 58%. The investor must bring cash, pay down the private loan first, or choose another structure.

Now run scenario B through a DSCR cash-out refinance. That loan replaces both liens with one new first lien, so total debt is the 58% payoff plus the 25% first mortgage, or 83% of value. Against the DSCR cash-out refinance ceiling of 75% LTV, the file lands 8 points over, so this route also needs cash or a smaller payoff. That gap is smaller than the 13-point HELOC shortfall, but it is still real. The property also has to show rent that covers the new payment, and the DSCR program’s minimum coverage is 1.00. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

The lesson is that two tests apply on every file. One is equity, and the other is how the lender qualifies you.

What Happens When the Payoff Is Bigger Than the Room?

When the payoff exceeds the available room, the line cannot retire the private loan by itself. You then have four realistic choices.

1. Bring cash to cover the gap at closing.

2. Pay down the private loan before applying, if the loan terms allow it.

3. Add collateral. A line on a different property can pay off a loan secured by the first one. The private lender must still release its lien, and the new collateral’s CLTV and title rules apply.

4. Switch products. A DSCR cash-out refinance can leave more room on some files, because its 75% LTV ceiling may sit above the cap of a given equity line. The worked example shows it does not always close the gap.

This situation is common after a purchase-plus-rehab financed at a high share of cost. Hard money and private loans are often sized against project cost, so the balance can sit above what any equity line will allow. Ownership length also matters, because it can decide whether a lender sizes on appraised value or on what you paid. Seasoning is the waiting period a lender wants between buying a property and refinancing it. Many DSCR cash-out programs expect about 6 months, measured from title recording. Before that point, a lender may size on your purchase cost, which can cap the payoff well below appraised value. An equity-line lender may have a different rule, so ask early.

Lien Position Decides Whether the Line Works

Lien position follows recording order, not the name of the product. The private loan was probably recorded first. A new line lender will normally want first position, or second behind a first mortgage that stays.

That has a practical consequence. The private loan must be paid off at closing and its lien released. It cannot stay behind, and it cannot sit ahead of the new line. If another junior lien exists, it has to be paid off or subordinated.

A first-lien line also complicates the future. A later refinance needs its own first position, which means payoff or subordination of the line. Plan that exit before you sign.

Can You Put the Line on an LLC-Owned Rental?

Often no. Many equity-line lenders lend only to individuals, or to individuals holding title in a revocable trust. Private loans, by contrast, are frequently made to LLCs. So an investor who borrowed through an LLC may have to deed the property out of it to get a line, which has its own consequences for insurance, liability, and title.

A DSCR loan can be made to an LLC, subject to lender program eligibility. For many investors with entity-held rentals, that fact alone moves the decision toward the DSCR route.

Who Qualifies for the Line, and How Does DSCR Differ?

An equity line is underwritten mainly on you. The lender reviews your credit, your debt-to-income ratio, your reserves, and your equity.

A DSCR loan flips that. The lender tests whether the property’s rent covers its full monthly obligation, which is principal, interest, taxes, insurance, and any HOA dues (together, PITIA). The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.

These are typical ranges from select lenders in Lendmire’s network, and they vary by file:

• Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
• Credit: a 620 floor exists in parts of the network. Most programs want around 660, and 700 or higher opens the strongest leverage tiers.
• Reserves: commonly around 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000.
• Loan size: up to $3,000,000 on standard programs.
• Property types: manufactured homes, log homes, and barndominiums are not offered.

Clearing 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation, so size your own cushion beyond it.

A larger equity cushion can improve coverage by shrinking the payment. It does not erase leverage caps, credit floors, or reserve rules. The strongest files clear both tests at once. Lendmire’s complete DSCR loans guide covers those tests in full.

HELOC or DSCR Exit: A Decision Table

On term structures, the 30-year fixed is the spine of DSCR lending. Extended terms and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want one.

This one is a genuine toss-up on some files. A low balance against high equity, held in your own name, can suit a line. A large balance, an LLC, or a portfolio of loans usually points to DSCR.

The Payoff Sequence, Step by Step

1. Order the payoff statement early. It is not the balance on your last statement. It includes interest through the closing date plus fees, and a stale letter has to be refreshed.

2. Confirm the lien order on title, and identify anything else recorded.

3. Size the line using value × cap − liens that stay, with the payoff and closing costs inside it.

4. Expect an appraisal. Valuation methods vary by lender and line size.

5. Qualify the borrower. An equity line reviews you. A DSCR file reviews the rent against the payment, plus credit and reserves.

6. Close and draw. A payoff this size is usually a large first draw. Some lines require an initial draw at setup, and the lender will state its own rule.

7. Verify the release. The title company pays the private lender from proceeds. Confirm that a recorded release appears on title afterward.

Watch the private loan’s maturity date. Private loans are short-term, so a balloon due date can force the timetable before your refinance is ready. Line up the exit before the maturity date, not after it.

Many investors also refinance out of hard money into long-term DSCR financing once the property is stabilized. The hard money exit refinance program is how Lendmire brokers that path.

What Are the Risks of Swapping a Private Loan for a Line?

You trade a fixed-term loan for a variable-rate line, which moves rate risk onto you. Most lines also have a draw period followed by a repayment period, and payments can change sharply when the draw period ends.

The rental is the collateral. The Consumer Financial Protection Bureau’s HELOC explainer defines equity as the home’s value minus what you owe, describes the draw and repayment structure, and warns that you could lose the property if you fall behind. On a rental, that warning applies to the asset that produces your income.

The formula itself is not rental-specific. The CFPB’s HELOC booklet shows the same method: take a percentage of appraised value, then subtract what you owe. Use it for the arithmetic only, because it is written for owner-occupied homes and says nothing about rental caps.

Key Terms Defined

CLTV (combined loan-to-value): total debt secured by the property, including the new line, divided by the property’s value.

Lien position: the order in which loans get repaid if the property is sold or foreclosed, set by recording order.

Payoff statement: the lender’s written figure for retiring a loan on a specific date, including interest and fees.

Draw period: the stretch when you can borrow against the line, usually followed by a repayment period.

DSCR (debt service coverage ratio): monthly rent divided by the full monthly PITIA, used to test whether the property covers its own payment.

Seasoning: the waiting period a lender wants between a purchase and a refinance.
