How an Investment Property HELOC Works in Order to Buy an Investment Property

The Quick Read: A home equity line of credit (HELOC) is a revolving loan secured by property you already own, and investors draw on it to fund the down payment and closing costs on a rental, which a separate purchase loan then finishes financing.

• You cannot open a line on a property you have not bought. The collateral is your home or a rental you already hold.
• Across Lendmire’s wholesale network, a line on an investment property tops out at 70% CLTV (combined loan-to-value), with a $500,000 maximum line and a 700 minimum credit score.
• A line on your primary residence can reach up to 90% CLTV, but only with a 720-or-better credit profile.
• Two lenders, two approvals. Qualifying for the line does not guarantee the purchase lender accepts the draw.
• Subject to lender guidelines, the line suits an investor who can carry its payment even if the new rental sits empty for a while.

Key Terms Defined

Four terms carry most of this topic. Learn them once and the rest reads easily.

CLTV (combined loan-to-value): All loans secured by a property, added together, divided by its value. A first mortgage plus a new line both count.

Draw period: The stretch when you can borrow from the line and typically pay interest only. After it ends, you repay principal and interest on a fixed schedule.

Lien position: Your place in line if the property is ever sold to pay debts. The lines discussed here can sit in first or second position.

DSCR (debt service coverage ratio): Monthly rent divided by the property’s monthly PITIA, meaning principal, interest, taxes, insurance, and any association dues. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.

Can You Open a Line on a Property You Haven’t Bought Yet?

No. A line needs collateral that exists today, so the purchase and the line are always two separate transactions.

Investors use the phrase “investment property HELOC” for two different setups. A practitioner walkthrough from Taxstra separates them cleanly.

Path A: a line on your primary home. You draw cash against your home’s equity. That cash becomes the down payment on a rental. Your home is the collateral at risk.

Path B: a line on a rental you already own. You borrow against that rental and spend the money on the next one. Experian calls this the less common product. Many banks simply do not write it.

Either way, the line is a funding source and not a purchase loan. The lender that opens your line does not finance the new property. A DSCR or other investment loan does that.

How Underwriting Treats the Line, Step by Step

The line is underwritten on you and your equity. The purchase loan is underwritten on the new property’s rent. Keep that split in mind through every step below.

1. The equity test. The lender totals every loan on the collateral and divides by its value. That is CLTV. Equity is value minus what you owe. On an investment property in Lendmire’s network, the ceiling is 70% CLTV. On a primary residence, the ceiling reaches 90% CLTV, and that top tier exists only at 720 or better.

2. Credit and debt review. An investment line requires a 700 minimum score, and credit above 700 buys eligibility rather than extra leverage. Both investment tiers, 720 and 700, top out at the same 70% CLTV. The lender uses a single-bureau score tied to the primary wage earner. Debt-to-income can run to 50% at most, calculated on the interest-only payment at the maximum draw.

3. Valuation. A line of $500,000 or less ordinarily uses an automated valuation instead of a traditional appraisal. A borrower can still request a full appraisal.

4. Title and vesting. The borrower must hold title personally or through a revocable living trust. This surprises people, so see the edge cases below.

5. The draw. At least 75% of the line is drawn at closing. Treat the line as a loan you are mostly borrowing on day one, not a standby reserve you tap lightly. Later draws start at a $1,000 minimum on some structures.

6. Repayment. The CFPB explains that borrowing stops when the draw period ends and a repayment period begins. It also notes that a HELOC’s cost usually floats, so the payment can change from month to month. Some lenders let you convert part of the balance to a fixed payment. On the lines placed through Lendmire’s network, pricing floats through both the draw and repayment periods and never converts.

On an investment line, the structure is a 5-year interest-only draw followed by 25 years of full amortization. Primary-residence lines offer two choices: a 3-year draw with 17 years of repayment, or the same 5-and-25 structure. Both sit in first or second lien position, and lines run from $25,000 up to a $750,000 maximum on a primary home.

Two Collateral Choices, Side by Side

The collateral decides which asset you put at risk and how much leverage you can reach. This table shows the network’s structural differences.

Eligible property types include single-family, 2-4 units, PUDs, townhomes, and condos. Manufactured homes, co-ops, condotels, and log homes are not offered. Title must sit with you or your revocable trust, and an LLC cannot hold it.

Benzinga points out the sharp edge on both paths: missed payments put the collateral at risk, including an investment property. That risk stays even when you spent the money elsewhere.

A Worked Example in Percentages

Run the numbers on a rental purchase using shares of value, not dollar amounts. These are modeled assumptions, not market data.

Say you own a home, and its first mortgage equals 40% of its value. You hold a 720-plus credit profile. A primary-residence line can reach 90% CLTV, so up to 50% of the home’s value is theoretically available to borrow against.

You want a rental priced at half the value of your home. Your DSCR purchase loan finances 75% of the price, so you need 25% down plus closing costs. That down payment equals 12.5% of your home’s value. Add closing costs and you still draw well under the 50% ceiling. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

The sizing matters for another reason. At least 75% of the line is drawn at closing, so a bigger line than you need means paying interest on money sitting idle. Size it to the deal.

Now the rental side. Suppose the rent clears the 1.00 coverage level on the new property’s own PITIA. That is the point where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.

Here is the catch. A 1.00 ratio does not mean positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. Your line payment sits outside it too, but it still has to be paid from somewhere.

How the Purchase Loan Treats the Draw

The purchase lender decides whether borrowed down-payment money counts. This is the gate most investors check too late.

Select programs reach 85% LTV (15% down) with roughly a 700-plus score. A larger down payment lowers the payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

Credit expectations vary. A 620 floor exists in parts of the network, most programs want around 660, and 700-plus unlocks the strongest leverage tiers. Reserves vary by lender, leverage, loan size, and transaction type, commonly around 6 months of PITIA. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months.

The line payment generally sits outside the new property’s PITIA, so it does not lower the new property’s coverage ratio. What the purchase lender cares about is where your cash came from. Policies differ by program. Some accept documented line proceeds. Some cap the borrowed share. Some want part of the down payment unborrowed, and borrowed money is often barred from reserves.

So ask before you draw. Move the proceeds into a dedicated account, and keep the paper trail clean. This is one of those rules that varies enough between lenders that no article can promise it for yours. For the full mechanics of the purchase loan, read the complete DSCR loans guide.

Where the General Rule Breaks

The simple story is: borrow equity, buy rental, repay line. Several edge cases bend it.

Your property sits in an LLC. Neither line structure lets an LLC, corporation, partnership, or irrevocable, blind, or land trust hold title. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead. That is the sharpest structural difference from a DSCR loan, where LLC vesting is common subject to lender program eligibility.

You own a lot of properties. A borrower is limited to three lines in total. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible. A line is a tool for a few deals, not a scaling engine.

The home you’d borrow against is in the wrong state. Lendmire arranges these lines only in the 16 states where it offers full-service lending. That is narrower than the 41-market DSCR footprint, which includes Washington, D.C.

The property type is off the menu. Manufactured homes, co-ops, condotels, log homes, and commercial or mixed-use zoning are not offered. Barndominiums fall in the same bucket for DSCR.

Your history has a mark. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4.

The payment steps up. Drawing interest-only means the payment jumps when repayment starts. The CFPB’s HELOC booklet warns that variable-cost lines can change payments even when you borrow nothing more, and that a balloon payment can put the collateral at risk. Both lines here amortize fully after the draw, so the risk is a step-up rather than a balloon, but the step is real.

Nearly full financing. If the line funds the entire down payment and the DSCR loan covers the rest, you are close to 100% financed. A single vacancy then hurts more than it would for an investor with real cash in the deal. Stress-test your cash flow before you commit.

Is This the Right Move?

It fits an investor with strong credit, meaningful equity, and a portfolio cash flow that can absorb a floating payment. It fits poorly when the plan only works if the rental fills immediately.

Think about which collateral you would rather risk. Path A ties the new deal to your home. Path B ties it to an income property, which keeps your residence out of it but caps leverage at 70% CLTV. An investor who owns rentals free and clear may prefer Path B. Someone with a heavily equity-rich home and a stable paycheck may prefer Path A. This one is a genuine toss-up that turns on your own balance sheet. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

If your existing rental is held in an LLC, a DSCR cash-out refinance may beat the line.

Plan the exit before you draw. You will pay the line down from cash flow, refinance it, or roll it into longer-term financing. Ask what happens if the refinance comes in smaller than the balance. Then you are paying the gap from your own pocket.
