How Much Can You Borrow on an Investment Property HELOC as a Standalone First Lien?

The Quick Read: It depends on the appraised value and any debt ahead of the line, but across the wholesale network Lendmire places these files with, an investment-property line tops out at 70% combined loan-to-value, minus existing liens, and never exceeds $500,000. A paid-off rental therefore gets up to 70% of its value, subject to that dollar cap. Everything below explains how that number is built and what can shrink it.

• Investment property ceiling: 70% combined loan-to-value (CLTV), with a maximum line of $500,000 and a minimum line of $25,000.
• Credit: 700 is the minimum, and a 720 score buys no extra leverage on an investment property.
• Title: the property must be held by you personally or by a revocable living trust, not an LLC.
• Drawn at closing: at least 75% of the line is drawn at closing, so this is not a standby line.
• Qualification: the line qualifies you as the borrower, not the property’s rent. All figures are subject to lender guidelines and full file review.

What Does Standalone First Lien Mean on a Rental?

A standalone first lien means the line is the only mortgage-style debt recorded against the property. Nothing outranks it. That happens in one of two ways: the rental is already paid off, or the line pays off the existing loan at closing.

This matters because lien position changes the math. A home equity line of credit (HELOC) is a revolving loan: you borrow, repay, and borrow again up to a limit. The CFPB explains that a HELOC behind an existing mortgage is a second mortgage. With no mortgage ahead of it, the same product sits in first position.

The programs Lendmire works with allow the line in either position. The sizing formula is identical. The only difference is how much debt gets subtracted before you see your number.

The Formula: How the Maximum Line Gets Sized

Your maximum line is 70% of the appraised value, minus every lien already recorded, and then capped at $500,000. That is the whole formula for an investment property on this network. Three inputs drive it: value, existing debt, and the dollar ceiling.

CLTV counts all liens plus the full credit limit of the new line. It does not count only what you have drawn. So a line you plan to draw lightly still uses its full size against the 70% ceiling.

Here is how the formula plays out in three common situations.

A free-and-clear rental. There are no liens to subtract. The line equals 70% of value, unless that lands above $500,000. Below the cap, the percentage decides your number.

A rental with a small remaining mortgage. Subtract the balance from 70% of value. If the line is also meant to pay off that mortgage, the payoff comes out of the line itself at closing, so the new line must be large enough to cover it and still leave cash. A small balance barely dents the number. A large one can leave little or nothing.

A high-value paid-off property. Here the dollar cap binds before the percentage does. Once 70% of value exceeds $500,000, extra equity stops adding borrowing power. A more valuable rental gets the same maximum line.

The minimum matters too. Lines start at $25,000, so a tiny sliver of leftover room under the percentage cap may not produce a usable line at all.

Why Investment Properties Get Less Than a Primary Home

On this network, the investment ceiling is 70% CLTV. Primary-residence and second-home lines can reach 90% CLTV, but only at a 720 or better credit profile.

NerdWallet reports that you won’t borrow as much against an investment property as against a primary home. Its figures describe the broader market, not this network, and many lenders there sit below 70% on investment lines. The network figure for an investment line is 70% CLTV, with no tier above it.

Credit works differently here than most people expect. Investment lines have a two-tier credit table: 700 and 720 both reach 70% CLTV up to $500,000. A higher score buys eligibility, not leverage. And 700 is a hard floor with no tier beneath it.

What Limits Your Number Besides Value?

Value and liens set the ceiling, but five other items decide whether you reach it. A line that clears the percentage test can still fail on credit, debt-to-income, title, property type, or exposure. Run through each one before you count on a number.

Credit. The minimum is 700 on an investment line. The score model uses a single bureau, keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not available. Derogatory history also counts. A bankruptcy needs 4 years of seasoning from discharge or dismissal. A foreclosure on an investment file needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4.

Debt-to-income. Maximum DTI is 50%. The lender reviews your file on the interest-only payment calculated on the maximum draw. So the full line, not just the drawn balance, counts against your DTI. That is a real constraint if you hold several rentals with mortgages of their own.

Title. The property must be held in your individual name or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If your rental already sits in an LLC, you need either a vesting change or a different product. Many investors in that spot look at a DSCR cash-out refinance instead, which is built for entity borrowers, subject to program terms.

Property type. Single-family, 2-4 unit, PUD, townhome, and condominium properties are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not offered.

Exposure. A borrower can hold only three lines at once, with combined exposure caps that depend on the program. A borrower with more than 15 financed properties is not eligible. Portfolio investors should check this before building a plan around several lines.

These lines are available only in the 16 states where Lendmire offers full-service mortgage lending. That is narrower than its DSCR investor footprint of 41 markets, including Washington, D.C.

How Is the Property Valued?

On this network, lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. Because an investment line caps at $500,000, an investment HELOC commonly closes without a full appraisal. A higher CLTV can trigger a secondary valuation, and you can request a full appraisal in any case.

That differs from what you may read elsewhere. Investment properties may require multiple appraisals. Valuation rules vary by lender, so this is one more reason to compare programs instead of assuming one lender’s process is universal.

The value is the property’s market value, not its rent. A standard investment HELOC does not look at rental coverage the way a DSCR loan does.

How Does the Line Actually Work Day to Day?

You draw during an interest-only period, then repay principal and interest over a longer period. On an investment line, the structure is a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats during both periods and does not convert to a fixed rate on this program.

The CFPB describes the general HELOC structure: a draw period, then repayment, and some plans require an initial draw or a minimum balance. The network here follows that pattern. At least 75% of the line is drawn at closing. After closing, each additional draw has a minimum of $1,000 (Texas is $4,000), as stated by the program with the 5-year draw and 25-year repayment structure.

That 75% draw requirement changes how you should think about the product. You cannot open a large line just to keep it in reserve. You will carry most of it from day one, with a variable cost.

Read the terms before you sign anything, because a floating balance can grow more expensive without any action on your part.

First-Lien HELOC vs. Second-Lien HELOC vs. DSCR Cash-Out

The three products solve different problems. A HELOC qualifies you as a borrower and gives you a revolving line. A DSCR cash-out refinance qualifies the property by its rental income and replaces your loan with a new fixed-term one. DSCR stands for debt service coverage ratio: monthly rent compared with the full monthly housing payment.

The DSCR cash-out ceiling applies to standard rentals; short-term-rental collateral tops out at 70% on a cash-out. Cash-out files commonly expect about 6 months of seasoning. Across most DSCR programs, 660 is the typical credit target, 620 exists in parts of the network, and 700+ opens the strongest leverage tiers. Standard loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders, and 1.00 coverage is where select programs start, not a universal standard. Eligibility depends on lender guidelines and file review. The complete DSCR loans guide walks through those requirements in detail.

Which one gives you more usable cash? It depends on the file. A paid-off rental held personally can pull up to 70% of value through a HELOC, capped at $500,000. The same rental under a DSCR cash-out can reach a higher percentage and a much larger loan, but you take a new fixed-term loan and the property must show enough rent coverage.

Keep one distinction straight. Clearing a 1.00 coverage ratio is not the same as positive cash flow. DSCR compares rent only to the housing payment. Repairs, vacancy, management, and utilities sit outside that calculation.

If you already hold a low-cost first mortgage, a second-lien line can leave it in place. A first-lien structure that replaces the old loan means giving that loan up. That tradeoff deserves a hard look.

Key Terms Defined

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

First lien: The loan with first claim on the property if it is sold or foreclosed.

Draw period: The stretch when you can borrow from the line and pay interest only.

Repayment period: The stretch after the draw period when you pay down principal and interest.

Line cap: The program’s maximum dollar line, which can bind before the percentage does.

Revocable living trust: A trust you can change or cancel, which can hold title the same way you would.

Where Investors Get Tripped Up

Free and clear does not mean 100% of value. The CLTV ceiling, not your equity, is the first limit. A fully paid-off rental still releases only the ceiling percentage.

A better score does not always mean more money. On an investment line, 700 and 720 reach the same ceiling.

A line behind a mortgage is a second lien, not a first. The same formula applies, with the first-lien balance subtracted.

Occupancy also matters. A line written against a primary home can restrict renting it out. Converting that home into a rental after closing can breach the agreement, so the right move is to disclose how you will use the property and get the product that matches.

Finally, a HELOC is not a no-risk standby fund. A DSCR loan has its own risks, but it gives you a fixed term and a structure built for rental income.

Which Path Fits Your Rental?

Match the product to how you hold the property and what you need from the money. Three quick checks usually settle it.

• Held personally or in a revocable trust, with a 700+ score, and you want revolving access: a first-lien HELOC may fit.
• Held in an LLC: a DSCR cash-out is the more natural route, per lender program requirements.
• You want a higher percentage or a larger loan than $500,000: compare a DSCR cash-out refinance, which can run to a 75% ceiling on standard rentals.
