How Much Can You Borrow on an Investment Property HELOC to Invest in Real Estate?

The Quick Read: It depends on your equity, but across the wholesale network Lendmire works with, an investment-property line tops out at 70% combined loan-to-value (CLTV) and $500,000, and you need a credit profile of 700 or better, with your existing mortgage balance subtracted from that 70% ceiling.

• The formula is property value times 70% CLTV, minus every lien already on the property, and the result cannot exceed $500,000.
• Credit above 700 buys eligibility, not extra leverage, because the 720 and 700 tiers both reach 70% CLTV on an investment property.
• At least 75% of the line is drawn at closing, so this is closer to a loan than to a dormant credit line.
• A line on your own home can reach higher leverage, but it puts your home behind the rental purchase.
• All figures are subject to lender guidelines and full file review, and none are a commitment to lend.

The Formula in One Line

The maximum line equals the property’s value times the CLTV cap, minus what you already owe on it. CLTV means combined loan-to-value: every loan secured by the property, added together, divided by its value. The new line’s full limit counts in that total, not just the part you plan to draw.

Say a rental is worth 100 units of value and carries a first mortgage equal to 50% of that value. At a 70% cap, the total debt allowed is 70 units. The first mortgage uses 50, so the line can be at most 20 units, or 20% of value.

That is why equity alone does not set your borrowing power. A rental with plenty of equity on paper can still leave a thin line once the first mortgage and the cap are applied. NerdWallet notes that a HELOC on an investment property is harder to get than one on a primary home, because lenders see higher default risk and fewer of them offer the product.

Why 70% and Not Higher?

Leverage on these lines is tiered by how the property is used. On an investment property, the network’s ceiling is 70% CLTV, with no tier above it. Primary-residence and second-home lines are a different tier, where the ceiling reaches 90% CLTV only at a 720-or-better credit profile. Separately, a primary-residence line above $500,000 caps at 75% CLTV and requires a full appraisal.

Investment-property lines have a two-tier credit table. A 720 score and a 700 score both reach 70% CLTV, so a higher score does not raise your amount. It only helps you clear the 700 hard floor, and nothing sits below it.

Treat any market figure you see as a general statistic, not a network term. The network figures here are the ones that apply when a file is placed through Lendmire.

Three Worked Examples

Run the numbers on three rentals, with each first mortgage shown as a share of value. All three assume the borrower clears the credit and income tests.

On a free-and-clear property, the $500,000 dollar cap binds before the percentage does once the property is valuable enough. The line is also available in first or second lien position, so a property with no mortgage is workable.

In the heavily financed case, a 5% sliver on a modest-value rental may fall below the $25,000 minimum line size. The formula can produce an answer that no lender will write. The minimum is lower only in Michigan, at $10,000.

What Else Can Shrink the Line?

Several tests sit on top of the formula, and any of them can pull the number down.

• Credit. The program floor for an investment line is 700. Credit reports must be no more than 90 days old at closing.
• Debt-to-income (DTI). DTI is your monthly debts divided by your monthly income, and the maximum is 50%. The payment is calculated on the interest-only amount at the maximum draw, so a large line weighs on DTI even if you never use it all.
• Valuation. Because an investment line caps at $500,000, and full appraisals are required only above that size, these lines are structurally in the automated-valuation lane. A traditional appraisal is not ordinarily needed, though a borrower may request one, and a higher CLTV may call for a second valuation.
• Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history on an investment file follows a 7-year path for a foreclosure and a 4-year path for a deed-in-lieu, pre-foreclosure, or short sale.
• Exposure. A borrower is limited to three lines. Combined exposure across them caps at $2,000,000 on the network’s higher-leverage program and $750,000 on its longer-runway program, while each investment line still stops at $500,000. Borrowers owning more than 15 financed properties are not eligible.

Business-bank-account deposit analysis needs a 680 minimum, but an investment line already floors at 700. For that reason, bank-statement income does not become the limiting factor on an investment line.

Which Properties and Titles Qualify?

Eligible collateral includes single-family homes, 2-4 unit properties, planned unit developments, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.

Title is the sharpest catch for investors. The property must be held by you as an individual or by your revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines.

If your rental already sits in an LLC, you have two options. You can change the vesting on the deed, which has its own legal and lender consequences. Or you can look at a DSCR cash-out refinance instead, which can work on LLC-titled property subject to lender program eligibility.

Availability is also narrower than the DSCR side. Lendmire’s home equity line placements run in 16 full-service states, versus a 41-market DSCR footprint that includes Washington, D.C.

Can You Borrow on an Investment Property HELOC to Invest in Real Estate?

Yes, you can use line proceeds toward a down payment, closing costs, or renovation on another rental, subject to the lender’s terms for the line. The harder question is whether the structure fits your plan.

Investment-property lines run one structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats during both periods and never converts to fixed. Because at least 75% of the line is drawn at closing, you start carrying cost on most of the line right away.

That makes it a poor match for money you might not deploy for months. A BiggerPockets Rookie podcast episode discusses using home-equity money as short-term capital for cash offers, with a plan to refinance into longer-term financing afterward. That is the strongest use case. Treat the line as a bridge to a long-term loan, not as the permanent debt on a 30-year hold.

The new purchase lender will also look at where your down payment came from. It may count the new line’s payment among your obligations. A line that already uses a large share of your 50% DTI ceiling can leave less room for the acquisition loan.

The stronger play for many investors is to split the jobs. Use the line as equity capital for the down payment. Then finance the acquisition itself with a loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Line on the Rental, Line on Your Home, or DSCR Cash-Out?

Each tool tests a different thing. The line on the rental tests you and the equity. The line on your home does the same with a higher ceiling and more personal risk. A DSCR cash-out tests the property’s income against its payment.

The home-line column deserves a pause. Leverage on a primary-residence line reaches 90% CLTV only at a 720-or-better credit profile, and a line above $500,000 is primary-residence only, capped at 75% CLTV with a full appraisal. The CFPB’s HELOC overview warns that you could lose your home if you cannot repay. Putting your residence behind a rental purchase is a real trade.

On the DSCR side, most files land at 75% to 80% LTV on a purchase, and cash-out tops out around 75% LTV on standard rentals. Many select programs start at a 1.00 coverage ratio, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Most programs want a score near 660, and 700 or better opens the strongest tiers. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, and utilities sit outside the ratio.

Lendmire’s complete DSCR loans guide walks through those numbers.

When the Line Makes Sense (and When It Doesn’t)

A rental line fits when you have meaningful equity, a clean credit profile, and a defined use for the cash within a short stretch. It also fits when you want money in hand for a cash offer. Lenders can freeze or reduce a line if values fall or your finances change, as the CFPB’s HELOC booklet explains. Plan as if the line could be smaller later than it is on day one.

It fits less well in four situations:

• Title sits in an LLC. The property must be re-vested first, or you use a DSCR cash-out.
• Your DTI is already near 50%. The full line, calculated at the maximum draw, can push you over.
• You plan many acquisitions. The three-line cap and the dollar limits mean a portfolio outgrows lines.
• You need long-term fixed-structure debt. Pricing floats on the line for its entire life.

Choosing between a line on the rental and a line on your home is a closer call. A line on the rental protects your home, but it caps at 70% CLTV. A line on your home reaches further and raises the stakes.

When long-term fixed debt is the goal, a DSCR loan is the alternative to weigh. Business-purpose DSCR loans are designed for non-owner-occupied investment properties, so they are reviewed differently from a standard owner-occupied mortgage. Their spine is the 30-year fixed, and select lenders in the network also offer 40-year terms, interest-only periods, and ARM structures. Above $2,500,000, the network generally holds to 30-year fixed. DSCR on manufactured homes, log homes, and barndominiums is not offered in the network.

Key Terms Defined

CLTV (combined loan-to-value): All loans secured by the property, including the new line’s full limit, divided by the property’s value.

Draw period: The stretch when you can borrow from the line, which here is interest-only for 5 years on an investment property.

Repayment period: The stretch after the draw ends, when you can no longer borrow and the balance amortizes over 25 years.

Automated valuation: A computer-generated property value used in place of a traditional appraisal on lines at or below $500,000.

Vesting: The legal form in which title to the property is held, such as an individual or a revocable living trust.

DSCR (debt service coverage ratio): Monthly rent divided by the monthly principal, interest, taxes, insurance, and any HOA dues.
