The Quick Read: A home equity line can pay medical bills, and five structures exist: a line on a primary residence, on a second home, on an investment property, a first-lien line on a paid-off property, or a rent-qualified DSCR cash-out refinance, each trading unsecured medical debt for debt secured by real estate. The right choice depends on which property carries the equity, how it is titled, and how much cash the bills require.
- Medical bills are usually unsecured debt, while a home equity line is secured by the property, so a missed payment puts the collateral at risk.
- The top combined loan-to-value (CLTV) tier depends on occupancy: 90% on a primary residence or second home at a 720 credit profile, but only 70% on an investment property.
- A property deeded to an LLC cannot hold one of these lines, which is where a DSCR cash-out refinance enters.
- A large share of the line is funded at closing, so it does not work like a pay-as-you-go account.
What a HELOC Is and Why Medical Bills Change the Math
A HELOC is a revolving line secured by a property. You draw funds during a set period, then repay through a longer amortizing period. The money is generally unrestricted, so it can pay hospital invoices, a collections account, or ongoing treatment costs.
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 catch is the type of debt. A hospital bill is typically unsecured. A collector generally cannot take your home directly over it, as this Yahoo Finance explainer notes. Once a HELOC pays that bill, the lender holds a lien and can foreclose if the line goes unpaid. Borrowers also give up some flexibility, because secured debt is harder to walk away from than unsecured debt. That is general information, not legal advice.
Many borrowers who own several properties have equity in more than one place. The question is rarely whether equity exists. It is which property should carry the lien and whether the file qualifies there.
Try These Steps Before Borrowing Against Anything
Home equity should come after the cheaper options, not before them. A short checklist helps:
1. Request an itemized bill and check it for coding errors and duplicate charges.
2. Ask the provider about financial assistance or charity care, which many hospitals run.
3. Negotiate the balance or ask for an interest-free payment plan.
4. Appeal denied insurance claims and apply any HSA or FSA funds.
5. Pay or dispute medical collections before you apply for a line, because a credit pull can still show them.
If the balance remains large after these steps, equity-based options make sense. The five below are sorted by which property carries the loan.
The Five Options at a Glance
| Option | Best fit | Main limit |
|---|---|---|
| 1. Primary-residence line | Owner with equity in their home | Top tiers need strong credit |
| 2. Second-home line | Vacation or second residence | 640 credit minimum |
| 3. Investment-property line | Individually titled rental | 70% CLTV ceiling |
| 4. First-lien line, paid-off property | Free-and-clear home or rental | Same occupancy ceilings apply |
| 5. DSCR cash-out refinance | LLC-held or rent-qualified rental | Replaces the existing first mortgage |
The five-option count is an organizing frame for this article. It is not a ranking. The wholesale network Lendmire works with covers the first four as standalone equity lines. The fifth is a different product with different underwriting.
Option 1: A Line on Your Primary Residence
A primary-residence line offers the widest leverage range of the five. Across the network, the maximum CLTV steps with the credit profile on a primary residence:
| Credit score | Max CLTV | Max line |
|---|---|---|
| 720+ | 90% | $500,000 |
| 700+ (720 on the longer-runway program) | 75% | $750,000 |
| 700+ | 85% | $500,000 |
| 660 to 699 | 85% | $500,000 |
| 640 to 659 | 80% | $500,000 |
| 620 to 639 | 70% | $400,000 |
| 600 to 619 | 60% | $400,000 |
These tiers are subject to lender guidelines and full file review. The 90% tier exists only at a 720-or-better profile. Lines run from $25,000 up to $750,000, and a line above $500,000 is primary-residence only, caps at 75% CLTV, and requires a full appraisal.
The tradeoff is concentration. This option puts the family home behind a medical bill, and it stacks a lien that reduces future borrowing room. For an investor, that lien can also crowd out equity that would otherwise fund the next acquisition.
Option 2: A Line on a Second Home
Second-home lines follow a tighter table. The ceiling is 90% CLTV at a 720 profile, 85% at 680 to 719, 80% at 660, and 75% at 640, with a 640 credit minimum and a $500,000 maximum line. A second home spares the primary residence, but it still puts a personal property at risk. Few investors own one, so this option fits a narrow group.
Option 3: A Line on an Investment Property
An investment-property line is the most restricted of the options. On an investment property, the ceiling is 70% CLTV, the credit minimum is 700, and the maximum line is $500,000. Investment lines use a single draw structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment.
Title is the sharp edge. The borrower must hold the property individually or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A rental already deeded to an LLC needs either a vesting change or a different product.
Leverage shrinks fast here. Take a rental with a first mortgage already near the 70% CLTV ceiling. It leaves almost no room, and the better answer is usually to wait or to look at option five.
Option 4: A First-Lien Line on a Paid-Off Property
These lines can sit in first or second lien position. On a free-and-clear home or rental, the line becomes the first lien, and no existing mortgage competes for the equity. The occupancy ceilings still apply, so a paid-off rental still tops out at 70% CLTV, and a paid-off primary residence follows the primary table.
A paid-off property is the strongest equity position an owner can borrow against. It is also the property where a lien feels most consequential, because the owner has no other mortgage on it.
How Underwriting Treats a Line, Step by Step
The same steps apply to options one through four.
1. Equity test. The lender compares the first mortgage plus the new line to the property value, then applies the CLTV cap for your credit tier and occupancy.
2. Credit. The network’s floor is a 600 score on primary residences, 640 on second homes, and 700 on investment properties. The score model is a single-bureau score keyed to the primary wage earner, and the report can be no more than 90 days old at closing.
3. Income and debt. Maximum debt-to-income is 50%, or 45% for scores from 600 to 679. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you actually draw.
4. Valuation. Lines at or below $500,000 ordinarily use an automated valuation, though a higher CLTV may require a secondary valuation. Every line above $500,000 needs a full appraisal, and a borrower may request one anyway.
5. Draw structure. Primary residences and second homes can choose a 3-year interest-only draw with a 17-year repayment, or the 5-year draw with a 25-year repayment. Pricing floats through both periods and never converts to fixed.
At least 75% of the line is drawn at closing on both structures. That matters for medical bills. A person facing staged treatment costs may not want most of the line funded on day one. If the total bill is known and due soon, the funding structure fits well. If costs are uncertain, the borrower pays on money they do not yet need.
The CFPB’s HELOC booklet also notes that lenders can freeze or reduce a line if home value falls or the borrower’s finances worsen. It describes the move from interest-only draws to full repayment as a payment jump to plan for.
Option 5: A DSCR Cash-Out Refinance
When an equity line does not fit, a DSCR cash-out refinance on a rental is the structural alternative. It replaces the first mortgage with a new loan sized above the old balance, and the difference comes to you as cash. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, rather than on personal income and debt ratios.
Across the network, standard rentals reach about 75% LTV on a cash-out refinance, while short-term-rental collateral caps at 70% on a cash-out. Credit starts at a 620 floor in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage. Loans generally reach up to $3,000,000 on standard programs, with smaller balances available through select lenders.
Coverage works like this: monthly rent divided by the full monthly obligation, which is principal, interest, taxes, insurance, and any HOA dues. A score of 1.00 is where select programs start. Select lenders in the network also offer a separate path with coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 does not equal positive cash flow, because repairs, vacancy, management, and utilities sit outside the calculation. Reserves vary by lender, leverage, and loan size, and they commonly run about six months of PITIA.
LLC-held rentals can use this route subject to lender program eligibility, which makes it the main path for entity-owned property. Lendmire’s complete DSCR loans guide covers how this product is built.
The costs of option five are real. A refinance replaces the existing loan, so you give up its terms, and loan sizes start higher than most medical balances. If the bills are modest, a line on an eligible property may fit better. If the bills are large and the rental carries strong coverage, the refinance may fit better. Picture a rental at roughly 1.2x coverage that is held in an LLC and carries a first mortgage well below 75% of its value. That file can pull cash out without touching a personal residence, and option three is not even available to it.
Where the General Rule Breaks
Medical collections on the credit report. A federal court in Texas vacated the rule that would have kept medical debt off credit reports. Consumer Finance Monitor reports the court found that federal law lets creditors use properly coded medical-debt information. The National Consumer Law Center says state laws and voluntary bureau actions now do the limiting. A lender can still see a medical collection, so credit tiers can still matter.
Recent derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits. One program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4, while the other declines that history entirely. Investment files follow the 7-and-4-year path.
Portfolio size. 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. An owner with more than 15 financed properties is not eligible. That can sideline a larger investor even with plenty of equity.
Property type. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Listed or recently purchased property. Rentals owned under about six months generally do not suit a cash-out, and a property listed for sale recently can be ineligible in some states.
Self-employed borrowers. A line is reviewed on the personal debt-to-income test, so tax returns that understate income can hurt. Lendmire’s piece 5 Bank Statement HELOC Options to Pay Off the Existing Mortgage covers documented-income routes. Option five sidesteps the issue by qualifying on the property’s rent.
Tax. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Availability. The equity-line programs described here are offered in Lendmire’s 16 full-service states. That is narrower than its 41-market DSCR footprint, which includes Washington, D.C.
How to Decide in Practice
Start with the title on each property. If a property sits in an LLC, options one through four are closed, and option five is the main path. If it is individually titled, check the CLTV tier for its occupancy before anything else.
Next, size the need. A bill that fits inside a small line suits options one through four. A bill that needs the large proceeds a refinance produces points toward option five, where coverage and reserves drive the file.
Then stress-test the exit. Because pricing floats and the line moves to full repayment, ask what happens if payments rise while income dips. For a rental, ask whether coverage still holds if personal obligations grow. For a personal residence, ask whether the household can carry the payment without the rental income at all.
Finally, compare against Lendmire’s separate piece 5 HELOC Options to Pay Off or Cover the Monthly Mortgage, which works through a related decision. Equity borrowing for a personal bill is a defensible move for some owners. It is a poor one when it drains the equity a stronger acquisition would have used.
Key Terms Defined
CLTV: Combined loan-to-value, the first mortgage plus the new line divided by the property value.
Draw period: The stretch when you can borrow from the line, typically with interest-only payments.
Repayment period: The later stretch when principal and interest are both due on a fixed schedule.
First-lien position: The line sits ahead of every other mortgage, which happens when the property has no existing loan.
DSCR: Debt service coverage ratio, the monthly rent divided by the full monthly housing obligation.
Vesting: How title is held, whether personally, in a revocable trust, or in an LLC.
Frequently Asked Questions
Can I use a HELOC on a rental to pay medical bills?
Yes, if you hold the rental individually or in a revocable living trust. On an investment property the ceiling is 70% CLTV, the credit minimum is 700, and the maximum line is $500,000. All of it is subject to lender guidelines and file review. An LLC-held rental needs a vesting change or a DSCR cash-out refinance instead.
Will medical collections stop me from qualifying?
They can matter, but they do not automatically disqualify a borrower. A lender sees collections on the credit report and weighs the overall score against the tier you need. Paying or disputing them before applying may improve the profile.
Does a line work for bills that arrive over time?
Only partly. At least 75% of the line is funded at closing, and a minimum subsequent draw of $1,000 applies on the longer-runway program. A borrower with uncertain, staged costs may be paying on more money than the bills require.
Is a DSCR cash-out better than an equity line for a large bill?
It can be, when the rental carries solid coverage and the bill is large enough to justify replacing the first mortgage. A line on an eligible property may fit better for a smaller bill. The choice turns on title, leverage, and what the existing first mortgage is worth keeping.
What if the rental does not cover its payment at 1.00?
Select lenders in the network offer a separate path for coverage below 1.00, with leverage and terms adjusted. Expect lower leverage and stronger credit expectations on that path.
