Best HELOC Program When You Want to Borrow Against 100% of Home Value

The Quick Read: A home equity line against 100% of a home’s value does not exist through the wholesale programs Lendmire places files with. On a rental property, the real ceiling is 70% combined loan-to-value, because lenders count your first mortgage and the new line together against the property’s value. The best program for your situation is the one that fits the occupancy type, credit profile, and equity you actually have.

• Full-value financing of this kind is not available through these programs, and the market-wide norm for equity lines is far lower.
• Ceilings depend on occupancy: 70% on an investment property, and up to 90% only on a primary residence or second home with a 720-or-better credit profile.
• Lines are held in an individual’s name or a revolving living trust, so an LLC-owned rental needs a different route.
• When a rental needs more cash than a line can supply, a DSCR cash-out refinance is usually the closer fit.

Why Does a 100% Home Equity Line Not Work?

A line at 100% of value leaves zero equity behind the lender, and that is why mainstream programs stop well short of it. The cap is measured on total debt, not just the new line. Consumer-finance coverage notes that limits on combined loan-to-value usually stop you from borrowing 100% of your home’s value, with many lenders capping at 80-85%. It also notes that property type, such as a primary home versus a vacation home, changes the limit.

Some credit-union products are marketed at full value on owner-occupied homes. That is a market-wide marketing claim, not a figure available through Lendmire’s network, and it does not extend to rentals. The network’s figures are lower and tied to occupancy, which the table below lays out.

The math shows why. Combined loan-to-value is your first mortgage balance plus the new line (plus any other liens), divided by the property’s value.

• Picture a rental valued at 100 units with a first mortgage at 65% of value. At the 70% investment ceiling, the room for a new line is 5% of value.
• A true 100% ceiling would imply 35% of value in new borrowing. That is the number people hope for, and it does not exist on these programs.
• If the valuation comes in 10% lower, the same first mortgage now sits at about 72% of value. The ceiling is already breached before a dollar of new line is added.

Value is half the equation. A modest swing in the valuation moves the answer more than most borrowers expect.

How Does Underwriting Actually Treat Combined Leverage?

Underwriting runs in a fixed order: value, liens, line size, then the borrower. Each step can shrink the number before the next one begins. Here is the sequence across the wholesale programs Lendmire works with.

1. Establish value. On lines at or below $500,000, an automated valuation usually replaces a traditional appraisal, though a higher combined leverage can trigger a secondary valuation. Every line above $500,000 requires a full appraisal, and a borrower may request one in any case.

2. Add every lien. The first mortgage, the new line, and any other recorded liens all count toward the combined figure.

3. Count the line, not just the draw. Underwriters generally treat the whole limit as borrowed, even if you plan to draw half. The cap applies to what you are approved for, not what you spend.

4. Apply the credit tier. Credit score does not set how much you can borrow. It sets which leverage tier you can reach. A higher score unlocks a higher ceiling, and a lower one pulls it down.

5. Test debt-to-income. The maximum is 50%, dropping to 45% for credit profiles from 600 to 679. Anything above 45% requires at least a 680 score. The test runs on the interest-only payment calculated against the maximum draw, so a large line counts at full weight.

6. Check title and property. Vesting and property type can end a file even when the numbers work. The edge-case section below covers these.

A home equity line of credit is an open-end line you can borrow against repeatedly during a draw period, followed by a repayment period. Available equity is home value minus what you owe on the mortgage. The same idea underlies every figure here, and it is why a nearly paid-off property supports more line than a freshly financed one.

What Are the Real Ceilings by Occupancy?

The ceiling depends on occupancy: 70% on an investment property, and 90% only on a primary residence or second home at 720 or better. On this network, the leverage tier you reach depends on both the property’s use and the credit profile.

Lower credit tiers step the ceiling down. On a primary residence, 700-plus supports up to 85%, 660-plus up to 85%, and 640-plus up to 80% on lines up to $500,000. A 600-plus profile sits at 60% on lines up to $400,000. Second homes floor at a 640 score, and investment lines at 700. These are typical guideline ranges, subject to lender guidelines and full file review, and not a commitment to lend.

For a rental, the table reduces to one line: 70% combined, 700 minimum credit, and a $500,000 cap on the line itself. Any line above $500,000 is reserved for primary residences, requires 700 or better (720 on the longer-runway program described in the next section), and caps at 75% combined leverage with a full appraisal.

Which Structures Exist for These Lines?

Lines come in two draw structures, and the choice affects how the balance behaves over time. They are standalone lines, in first or second lien position, placed through two wholesale programs. The higher-leverage program uses a three-year interest-only draw followed by 17 years of full amortization. The longer-runway program uses a five-year draw followed by a 25-year repayment. Tennessee shortens both structures (3-year/12-year and 5-year/10-year).

Investment lines run only the five-year draw and 25-year repayment structure. Both programs share these features:

• At least 75% of the line is drawn at closing. This is not a pure standby line that sits unused.
• Pricing floats through both the draw and the repayment period and never converts to fixed.
• Line size runs from $25,000 to $750,000 (Michigan’s floor is $10,000), with the larger sizes limited to primary residences.
• The minimum subsequent draw after closing is $1,000 where a program states one (Texas is $4,000).
• A borrower is limited to three lines, with combined exposure capped at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program.

A quoted figure always belongs to one program’s structure.

Where Does the General Rule Break?

Most denials come from edge cases, not from the leverage math. Each of these can change an answer a borrower thought was settled.

LLC-owned rentals. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. Only an individual borrower or an inter vivos revocable living trust qualifies. Many rental investors hold properties in entities, so this is the sharpest structural difference from a DSCR loan. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead. Whether an entity can borrow on a DSCR loan is subject to lender program eligibility.

Property types. Single-family homes, 2-4 units (640 minimum on the longer-runway program), PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Modular factory-built homes qualify on the longer-runway program only. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural zoning are not offered on either program.

Derogatory history. A bankruptcy needs four years of seasoning from discharge or dismissal. On primary residences and second homes, the programs split on foreclosure history. One seasons a foreclosure at seven years and a deed-in-lieu, pre-foreclosure, or short sale at four. The other declines the history entirely regardless of age. Investment files follow the seven-and-four-year path.

Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.

Portfolio size. A borrower owning more than 15 financed properties is not eligible, which matters to larger portfolios.

Texas homesteads. A Texas primary residence is a homestead and caps at 80% combined leverage. The higher matrix tiers never apply there. Texas second homes and investment properties follow the standard tables.

Geography. These lines are available only in Lendmire’s 16 full-service states (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA). That footprint is narrower than the company’s DSCR footprint of 41 markets, including Washington, D.C.

A hidden catch on primary homes. A line taken on a primary home does not authorize turning that home into a rental. The CFPB booklet on home equity lines warns that renting your home to others may be prohibited under the terms of your line. A borrower who plans to convert a primary residence to a rental should settle that question before taking the line.

What Is the Risk of Borrowing Near Full Value?

The main risk is that a line borrowed near the ceiling has no cushion if values slip. The same booklet explains that lenders may reduce your credit line if your home’s value declines significantly. It also says you generally must pay the line off in full when you sell. A borrower who maxes a line at a high ceiling is most exposed to both events at once.

Three problems tend to compound:

• Payment shape. Pricing floats and never converts to fixed, and at least 75% of the line is drawn at closing. So a meaningful balance is exposed to movement from day one.
• The draw-to-repayment transition. The interest-only draw ends and full amortization begins, so the obligation steps up once the draw period closes. A borrower who plans around the draw-period payment can be surprised.
• Stacking on a rental. A second lien on an already-financed rental adds to the monthly obligation. That can weaken the property-level coverage picture on the next DSCR purchase or refinance.

What Are the Closest Real Alternatives?

For most rental investors, the closest real alternative is a DSCR cash-out refinance, because it is reviewed on the property rather than the borrower’s personal income. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It is not a debt-to-income test, and it is not constrained by the individual-title rule above. Our complete DSCR loans guide covers how the ratio is built.

Across the network, a standard-rental cash-out tops out around 75% LTV, with about six months of seasoning a common expectation. That sits above the 70% investment-line ceiling, though it replaces your first mortgage rather than adding a second lien. Whether it comes out ahead depends on how much equity you have, what you owe, and whether the current loan terms are worth keeping. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

On coverage, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 does not mean the property produces positive cash flow, since repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. A higher coverage ratio generally opens better leverage and pricing.

Other routes depend on the profile:

• More than one home to tap. Lendmire’s piece Best Investment Property HELOC Program When You Want Multiple HELOCs on Different Homes explains the three-line limit in practice.
• A borrower who documents income through bank statements. Lendmire’s article Best Bank Statement HELOC Program When You Want to Borrow More on an Existing Loan covers that profile.
• A borrower with too little equity. If the numbers do not reach the ceiling at any tier, the better move is usually to wait, pay down the first lien, or look at a different property than to hunt for a higher-leverage product.

What Should You Prepare Before Applying?

A broker that shops several wholesale lenders can match a file to the right program, and preparation makes that match easier. The best program for a given borrower depends on occupancy, credit profile, equity, and title. Lendmire works as a broker with a multi-state network of wholesale HELOC lenders and is never the lender itself. A checklist helps:

• Occupancy and use. Be clear on whether the property is a primary home, second home, or rental, since that sets the ceiling.
• Vesting. Confirm title is held by you individually or in a revocable living trust.
• Credit. Pull your score early. The report cannot be more than 90 days old at closing, and no rescores are allowed. The score model is a single-bureau pull keyed to the primary wage earner.
• Tradelines and housing history. The longer-runway program wants two tradelines seasoned 12 months or one seasoned 24. It also wants a clean housing history applied across all financed properties.
• Existing liens. Gather every balance. The combined figure counts them all.
• Value expectations. Know that a valuation below your estimate can erase the room you counted on.

Key Terms Defined

Combined loan-to-value (CLTV): the first mortgage plus any other liens, including the new line, divided by the property’s value.

Draw period: the stretch when you can borrow against the line, typically paying interest only.

Repayment period: the stretch after the draw ends, when the balance is paid down through full amortization.

Lien position: whether the line sits first in line for repayment or behind another mortgage.

DSCR: debt service coverage ratio, meaning monthly rent divided by the property’s monthly principal, interest, taxes, insurance, and any HOA dues.

Vesting: the legal form in which title to the property is held.

Next Step

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. The practical lesson from the math is that the ceiling is set by value, existing liens, and occupancy, and no program lets those add up to a full 100%.
