The Quick Read: The amount of business debt a primary-home HELOC can retire is set by your equity, your credit tier, and the line’s dollar cap, not by what the business owes. On a primary residence in Lendmire’s wholesale network, the combined-loan ceiling rises with your credit score, so stronger credit allows a higher share of the home’s value to be borrowed against. Your home then backs the debt you paid off.
- The line size is roughly (home value × allowed combined ceiling) minus every lien already on the home.
- On a primary residence, the top 90% tier needs a 720 score and caps the line at $500,000.
- At least 75% of the line is drawn at closing, so oversizing the line means borrowing money you don’t need.
- Debt payments are tested on the interest-only payment for the maximum draw, with a 50% debt-to-income ceiling.
- LLCs cannot hold title on these lines. Investors with rentals titled in an entity often belong in a DSCR cash-out instead.
What Does “Retiring Business Debt” With a Home Line Actually Mean?
It means you borrow against your own house and use the cash to pay off business obligations: cards, term loans, equipment financing, merchant advances. The new line is personal debt secured by your home. The old debt is gone.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
The lender does not ask what the debt is. It sizes the line on the home’s value, your credit, and your personal debt load. The business debt matters in only two ways. Its payoff total has to fit under the line. And if it showed on your personal file, its payment may drop out of your debt-to-income ratio once it is paid and closed.
Equity is the home’s value minus what you owe on it. A line borrows against that gap. The sizing formula is the same whether the money buys a truck or pays off a business loan. CBS News walks through the arithmetic: value times the lender’s maximum combined ceiling, minus existing liens.
Two wholesale programs sit behind the lines Lendmire brokers: a higher-leverage program and a longer-runway program. Where they differ, a figure below applies only within its own program. Lendmire is the broker, never the lender, and every figure is subject to lender guidelines and full file review.
How Is the Maximum Calculated, Step by Step?
Start with the home’s value and end with the payoff total. Five steps get you there, and the credit tier decides the ceiling in step two.
1. Value the home. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher combined ceiling may require a second valuation. Every line above $500,000 needs a full appraisal.
2. Find your ceiling. Credit score sets the maximum combined loan-to-value (CLTV), which counts the first mortgage plus the new line. The table below shows the primary-residence tiers.
3. Subtract liens. Take value times the ceiling, then subtract the first mortgage and any other lien. The remainder is the most the line can be.
4. Apply the dollar cap. The tier shows its own cap. Lines run from $25,000 to $750,000 in total.
5. Compare to the payoff total. If the business debt is larger than the line, it does not fit. If it is smaller, size the line near the payoff, not near the maximum.
| Credit score (primary residence) | Max CLTV | Line cap |
|---|---|---|
| 720+ | 90% | Up to $500,000 |
| 700+ or 720+ | 75% | Up to $750,000 |
| 660+ (700+ also at this tier) | 85% | Up to $500,000 |
| 640+ | 80% | Up to $500,000 |
| 620+ | 70% | Up to $400,000 |
| 600+ | 60% | Up to $400,000 |
Read the first two rows together. A 720 borrower on a primary residence faces a real tradeoff: 90% CLTV up to $500,000, or a larger line up to $750,000 at a reduced 75%. A line above $500,000 is primary-residence only. It requires a score of 700 or better (720 on the longer-runway program), caps at 75% CLTV, and needs a full appraisal.
Market surveys report that many banks and credit unions allow 80% to 85% combined ceilings on home equity lines, per CBS News. That describes the broader market. The network figures above are the ones that apply to the files Lendmire places. The consumer-finance regulator also says that equity alone does not set the line, and lenders can stop further draws if circumstances change. More on that below.
What Does the Math Look Like?
These are illustrations, not market data. They use percentages of home value so the logic is easy to see.
Scenario one: the debt fits. Say your home carries a first mortgage equal to 50% of its value. You have a 720 score. The 90% ceiling leaves room for a line of up to about 40% of the home’s value, subject to the $500,000 cap. Your business debt totals 25% of the home’s value. It fits, with room to spare. Because at least 75% of the line is drawn at closing, you size the line close to that 25%. Don’t take the full 40% just because it’s offered.
Scenario two: the debt does not fit. Now say the first mortgage equals 70% of value and your score is 700. The 85% ceiling leaves about 15% of value. The same business debt, at 25% of value, is too large. Options: retire the highest-cost piece only, bring in a different tool, or wait for the first mortgage to pay down.
Run the numbers on the first scenario once more with a 640 score. The ceiling drops to 80%, so the room falls to about 30% of value. Still fits. Drop to 620 and the ceiling becomes 70%. Room: about 20%. Doesn’t fit. Credit tier moves the answer as much as equity does.
How Does Underwriting Treat Your Business Debt and Income?
The underwriter reviews you personally, and the business debt matters only as it appears on your file. A business loan you guaranteed may be on your credit report. A loan that never reported may not count at all.
Here is what the review covers:
- Credit. The program floor is a 600 score. The score model is single-bureau and keyed to the primary wage earner. The report can be no more than 90 days old at closing, with no rescores.
- Debt-to-income. The maximum is 50%. Profiles from 600 to 679 are held to 45%, and a ratio above 45% requires a 680 minimum.
- The payment test. Qualification uses the interest-only payment calculated on the maximum draw. It does not use what you actually drew. This is why a bigger line than you need can hurt approval. You pay for headroom on paper.
- Income documentation. Self-employed owners can qualify on documented income under the applicable program, subject to lender guidelines. Business bank-account deposit analysis requires a 680 minimum. On a primary residence, where the floor is 600, that is a real gate. A 640 borrower can qualify for the line but cannot use business accounts.
- Credit history. Tradeline and housing-history standards vary by program. A bankruptcy needs 4 years of seasoning from discharge or dismissal on both programs.
Pay creditors directly where you can, and get payoff letters. Keep the draw separate from other money. Then close or reduce the paid accounts so the lower obligations show up in your next review.
What Structures Exist?
The line is a standalone loan in first or second lien position. Two draw structures exist on primary residences and second homes:
- A 3-year interest-only draw followed by a 17-year fully amortizing repayment.
- A 5-year interest-only draw followed by a 25-year fully amortizing repayment.
At least 75% of the line is drawn at closing on both programs. The cost floats through both the draw and the repayment period and never converts to fixed. That is the opposite of most business term debt. You are swapping a fixed obligation for a floating one, which moves risk onto you. After closing, the minimum subsequent draw is $1,000 under the longer-runway program’s terms.
Property types matter too. Single-family homes, 2-4 units, PUDs, townhomes, and condominiums (including non-warrantable) are eligible. Modular factory-built homes are eligible on the longer-runway program only. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Where Does the General Rule Break?
The formula works until one of these edge cases shows up.
Title held in an entity. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. Title must sit with you personally or in a revocable living trust. This is the sharpest difference from a DSCR loan. A property already deeded to an LLC needs a vesting change or a DSCR cash-out.
The line can freeze. The CFPB’s HELOC explainer says a lender may stop further draws if the home’s value drops significantly or your finances change. A payoff plan that depends on future draws is fragile. Draw what you need at closing and pay the creditors then.
Rental restrictions. The CFPB’s HELOC brochure notes that renting out the home may be prohibited under line terms. House-hackers should read the terms before borrowing.
Exposure limits. A borrower is limited to three lines. 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. Portfolio investors hit this wall first.
Recent derogatory history. Foreclosure-family history splits by program on primary residences. One program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other declines the history regardless of age.
Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in several states.
Availability. HELOC placement runs through Lendmire’s 16 full-service states. That is narrower than the 41-market DSCR footprint, which includes Washington, D.C.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Which Business Debts Should Move, and Which Should Stay?
Move debt that is expensive, short-fused, or already tied to you personally. Leave debt that is cheap, fixed, and ring-fenced inside the entity. Once a debt moves, your house secures it.
| Debt type | Move it? | Reason |
|---|---|---|
| Personally guaranteed card or loan | Often | Already reaches you. Little new risk. |
| Merchant advance or short-term loan | Often | Short fuse and heavy cash drain. |
| Equipment loan secured by the asset | Usually not | Already secured. Moving adds collateral risk. |
| Entity-only term loan, fixed, stable | Usually not | Your home was never exposed. |
| Debt larger than your line room | Partly | Retire the costliest slice only. |
An entity does not shield your home once you borrow against it personally. Before you move anything, run a lean-month test: could you cover the line’s payment in your slowest month if the business earns nothing? If not, don’t move the debt.
When Should an Investor Look at DSCR Instead?
If the underlying debt sits on rental real estate, a DSCR cash-out refinance may fit better than a home line. DSCR loans qualify primarily on property-level rental income covering the payment, subject to lender guidelines. They are built for non-owner-occupied investment properties.
Here is how the pieces compare across the network:
- Cash-out on a standard rental: tops out around 75% LTV, and about 6 months of seasoning is the common expectation.
- Purchase: most files land at 75% to 80% LTV on a purchase, and select programs reach 85% LTV at roughly a 700+ score.
- 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. Scores of 700+ unlock the strongest tiers.
- Investment-property HELOCs: lines on an investment property cap at 70% CLTV and $500,000 total, on the 5-year draw and 25-year repayment structure only.
One caution. Clearing 1.00 coverage is not the same as positive cash flow. The ratio compares rent to the payment (principal, interest, taxes, insurance) and ignores repairs, vacancy, management, and utilities. A home line’s payment generally sits outside the DSCR calculation but still drains real cash.
White Coat Investor notes that a primary-residence line is generally easier to obtain than one on an investment property. That is the trade. A home line is easier and puts your house at risk. A DSCR cash-out keeps the debt on the rental. For a deeper walk through DSCR terms, see Lendmire’s complete DSCR loans guide. For the savings side, Lendmire’s piece How Much a Business Owner Saves Retiring Business Debt With a HELOC covers the cost comparison. To test affordability, see how much cash flow a rental needs to cover a primary-home HELOC payment.
Equity is a finite budget. Every dollar drawn to retire business debt is a dollar you cannot use for a down payment, a refinance, or reserves. The strongest files clear both tests: enough equity and enough coverage.
Key Terms Defined
CLTV (combined loan-to-value): All loans secured by the home, added together, divided by the home’s value.
Lien position: The order in which lenders get paid from the home if it is sold. A first lien is paid first; a second lien is paid after.
Draw period: The stretch when you can borrow from the line, usually paying interest only on what you’ve drawn.
DSCR: Debt service coverage ratio. Monthly rent divided by the monthly payment (principal, interest, taxes, insurance, and any HOA dues).
Interest-only draw: A phase where payments cover interest but do not reduce the balance.
Frequently Asked Questions
Can I pay off business credit cards with a primary-home HELOC?
Yes, mechanically. The lender sizes the line on the home, your credit, and your personal debt-to-income ratio, not on what the draw is spent on. The payoff total has to fit under the line, and the card debt should be personally guaranteed or on your file for the move to improve your ratios.
Does an LLC protect my home from the debt I move?
No. Once you borrow personally against your home and use the cash to retire the debt, the home secures the new loan. The entity does not stand between you and the line. LLCs also cannot hold title on these lines at all.
Will my business debt count against me?
Only to the extent it shows on your personal file. A guaranteed loan that reports to your credit may count. A debt that never reported may not. The payment test also runs on the interest-only payment for the maximum draw, so an oversized line can raise your ratio.
How much should I draw?
Draw close to the payoff total. At least 75% of the line is drawn at closing, so a line sized far above your need puts extra money into a balance you pay on. Size the line to the debt you intend to retire, plus a modest buffer if the lender allows it.
What if my income dips after I retire the debt?
Lenders may stop further draws if the home’s value drops significantly or your finances change, per the CFPB. The cost also floats and does not convert to fixed. Run a lean-month test before you move the debt, not after.
