The Quick Read: Few lenders write a home equity line secured by a rental, and those that do underwrite you personally, not the property’s rent. On Lendmire’s network, an investment line tops out at 70% combined loan-to-value (CLTV) with a 700 minimum credit score, and the line cannot exceed $500,000, subject to lender guidelines.
- The collateral is the rental. Your income, credit, and debt load decide the file, not the rent alone.
- Investment lines cap at 70% CLTV, with a 700 score floor and a $500,000 maximum line.
- Title must sit in your name or a revocable living trust. An LLC cannot hold title on these lines.
- The line is variable, interest-only for five years, then fully amortizing for 25 years.
- If your rental sits in an LLC, or you need more leverage, a DSCR cash-out refinance is usually the better tool.
What Is a HELOC Against a Rental Property?
It is a revolving line of credit secured by a rental you already own. You borrow against the equity, which is the property’s value minus what you owe on it. The line sits in first lien position if the rental is paid off, or second lien behind an existing mortgage.
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.
Two different products share this name, and the search results blur them.
1. A line on your primary home, used to fund a rental. The home is the collateral. This is the more common route, and it puts your own house at risk.
2. A line on the rental itself. The rental is the collateral, and your home stays out of the deal. This is the narrower product, and it is what this article covers.
A line cannot buy a property you do not own yet. It draws on equity in something you already hold. A purchase still needs its own loan.
Lendmire is a mortgage broker, not a lender. It places these lines through select wholesale partners, and every figure below is subject to lender guidelines and full file review.
Why Do So Few Lenders Offer It?
Lenders see more default risk on a rental than on a borrower’s own home. NerdWallet reports that not all lenders offer these lines and that qualification is stricter. Experian likewise describes an investment-property HELOC as less common than one on a primary home.
The logic is simple. A borrower in trouble pays the mortgage on their own home first. The rental line gets paid second.
So a “no” from your own bank is common. It says little about your deal. It usually means that bank does not write the product.
The lenders that do write it vary by property type, title, leverage, and credit profile. Big banks, community banks, credit unions, and online lenders each draw the line in different places. A broker that shops multiple wholesale lenders can match your file to a program that fits, instead of you cold-calling one institution at a time.
How Does Underwriting Treat a Rental Line, Step by Step?
Underwriting is built around you, not the rent. Here is the sequence a file typically follows.
1. Eligibility screen. The lender checks the property type, occupancy, and how title is held. Many files die here, before any math.
2. Credit check. On our network, an investment line needs a 700 minimum score. The report is a single-bureau score keyed to the primary wage earner, and it cannot be more than 90 days old at closing.
3. Debt-to-income (DTI). DTI is your monthly debts divided by your gross monthly income. The maximum is 50%. The line is qualified on its interest-only payment calculated on the maximum draw, not on what you plan to borrow.
4. Combined leverage. CLTV adds your first mortgage balance and the new line, then divides by the property’s value. Investment lines cap at 70% CLTV.
5. Valuation. Because an investment line caps at $500,000, and full appraisals are required only above that size, the file runs in the automated valuation lane. It commonly closes with no traditional appraisal. A higher CLTV may call for a second valuation, and you may request a full appraisal in any case.
6. Documents. Expect income proof, proof of insurance, and a mortgage statement if there is a first lien. Leases and tax returns showing rental income are common asks on rental files. NerdWallet also lists proof of long-term tenants among the factors lenders weigh.
Some lenders count part of the rent as income. How much, and when, depends on the program. Lendmire covers that in its piece on when rental income counts toward qualifying for an investment HELOC.
One more point on credit. Market surveys, including NerdWallet, report scores of 720 or greater as typical. On Lendmire’s network, an investment line starts at 700. Both 700 and 720 reach the same 70% CLTV, so a higher score buys eligibility, not extra leverage.
What Does the Investment Line Look Like on Our Network?
Here are the typical parameters for an investment-property line, subject to lender guidelines and full file review.
| Feature | Investment line |
|---|---|
| Maximum CLTV | 70% |
| Minimum credit score | 700 |
| Line size | $25,000 to $500,000 |
| Draw period | 5 years, interest-only |
| Repayment period | 25 years, fully amortizing |
| Lien position | First or second |
| Valuation | Usually automated |
Several features matter in practice.
- Most of the line is drawn at closing. At least 75% of the line is funded on day one. This is not a standby line you open and leave idle.
- Pricing floats. It moves through both the draw and the repayment period, and it never converts to fixed.
- Later draws have a minimum. On the program that states one, it is $1,000.
- Above $500,000 is off the table for rentals. Larger lines are primary-residence only.
- Primary and second homes get more room. A primary-residence line can reach 90% CLTV, but only at a 720-or-better credit profile. That gap is one reason many investors tap their own home instead.
Where Does the Rule Break? (Title, Property Type, and Exposure)
The general rule says an investment line works if you have equity, credit, and income. The edge cases below can break it.
LLC title is the sharpest break. Title must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded into an LLC needs a vesting change, or a DSCR cash-out instead, subject to program terms. Many investors learn this only after they have applied.
Property type. Eligible types include single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Not eligible: manufactured homes, co-ops, condotels, log homes, commercial property, mixed-use property, and agricultural zoning. These types are not offered, full stop.
Portfolio size. A borrower can hold at most three lines. Combined exposure caps at $2,000,000 on the higher-leverage wholesale program and $750,000 on the longer-runway wholesale program. An investor with more than 15 financed properties is not eligible.
Credit events. A bankruptcy needs four years of seasoning from discharge or dismissal. Investment files follow a seven-year path for a foreclosure and a four-year path for a deed-in-lieu, pre-foreclosure, or short sale.
Listing status. In some states, a property listed for sale, or listed in the past 60 days, is ineligible.
No tenant history. A vacant or just-converted house is a weak candidate, since lenders want proof of tenancy.
Footprint. These lines are available in 16 of Lendmire’s full-service states. That is narrower than the DSCR investor footprint of 41 markets, including Washington, D.C.
How Do Payments Behave Over Time?
This is where investors get surprised. The CFPB explains that a HELOC has a draw period, then a repayment period in which you can no longer borrow. It also warns that monthly payments are often significantly higher once repayment starts, and in some cases the full balance can come due.
On the investment line, that means five years of interest-only payments. Then payments step up as the balance begins to amortize over 25 years. Since pricing floats the whole way, the payment can also change even if you draw nothing more.
So test the rental against the repayment-phase payment, not the draw-phase one. Interest-only is not cheap forever. It is a runway.
How Does the Math Work? (A Worked Example in Percentages)
Use round, hypothetical numbers, not real prices. Say a rental is valued at 100.
Mortgaged rental. The first mortgage is 45% of value. At a 70% CLTV ceiling, total debt can reach 70% of value. That leaves room for a line of up to 25% of value, capped at $500,000.
Paid-off rental. There is no first lien. The line can reach 70% of value, again capped at $500,000.
Heavily financed rental. The first mortgage is 68% of value. Only 2% of value remains under the ceiling, and the line has a $25,000 minimum. Most files like this do not work.
The thing to notice is that equity alone does not carry the file. You also need the credit score, the DTI, the eligible title, and the property type.
Which Tool Fits? (HELOC, DSCR Cash-Out, or Primary-Home Line)
The answer depends on your title, your leverage need, and how you document income.
| Factor | Rental HELOC | DSCR cash-out | Primary-home line |
|---|---|---|---|
| Collateral | The rental | The rental | Your home |
| Reviewed on | You: credit, DTI | Rent vs. PITIA | You: credit, DTI |
| LLC title | Not allowed | Per program terms | Not applicable |
| Payment | Floating, I/O then amortizing | Per loan structure | Floating, I/O then amortizing |
| Home at risk | No | No | Yes |
A DSCR cash-out refinance replaces your current mortgage with a bigger one and hands you the difference. It tops out around 75% LTV on standard rentals, and short-term rental cash-out tops out at 70%. About six months of seasoning is the common expectation. Most programs want a score around 660, with a 620 floor in parts of the network. A score of 700 or more opens the strongest leverage tiers. Standard loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders.
DSCR is the debt service coverage ratio: monthly rent divided by the full monthly payment on principal, interest, taxes, insurance, and any HOA dues (PITIA). A ratio of 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 is not the same as positive cash flow. Repairs, vacancy, management, and utilities sit outside the calculation.
The tradeoff is real. A HELOC keeps your existing first mortgage in place, which can matter if that loan is long-term and well priced. A DSCR cash-out replaces it. The HELOC is underwritten on you. The DSCR loan is underwritten on the property, which suits investors with many mortgages and modest reported income.

How Do You Choose a Lender Type?
The best program for your situation depends on property type, title, credit profile, leverage need, and documentation. Here is a practical way to sort it.
- Your own bank or credit union. Ask first. Some write rental lines if you already have deposits and a history there. Expect limits on property count and title.
- Online lenders and retail banks. Policies vary widely. Some exclude rentals entirely.
- A broker with a wholesale network. One application can be matched against several lenders’ guidelines. This is the model Lendmire uses.
Whichever route you take, ask these questions up front:
1. Do you write lines secured by non-owner-occupied property?
2. Is LLC or trust title allowed?
3. What is the maximum CLTV on an investment property?
4. Is the line first or second lien?
5. How much of the line is drawn at closing?
6. What happens to the payment at the end of the draw period?
7. Is the pricing fixed or floating?
8. Which property types and states are eligible?
Does a broker cost more? A broker is paid either by the lender or by you. The compensation is disclosed in your loan paperwork, and you should compare full terms either way.
What If You Are Declined?
First, find out which test failed. Common reasons are title, property type, credit, DTI, and leverage.
- Title failed: the rental sits in an LLC. Vest it in your name or a revocable trust, or use a DSCR cash-out instead, per program terms.
- Leverage failed: the first mortgage uses too much of the 70% ceiling. Wait for paydown or appreciation, or look at a refinance.
- DTI failed: your debts are too high against reported income. A rent-qualified DSCR loan may fit better.
- Credit failed: you are under 700. Raise the score, or look at products with lower credit floors.
- Property type failed: a mixed-use building, condotel, or manufactured home is not offered on these lines.
A decline on one product is not a verdict on the deal. It means a different structure may fit.
Key Terms Defined
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow against the line. On an investment line, it lasts five years and is interest-only.
Repayment period: the stretch after the draw ends, when you can no longer borrow and pay down the balance. On an investment line, it runs 25 years.
DTI (debt-to-income ratio): your monthly debts divided by your gross monthly income.
Lien position: your place in line to be repaid if the property is foreclosed. First lien is repaid before second.
DSCR: the ratio of a property’s rent to its full monthly payment (PITIA). It qualifies a loan on the property instead of on you.
PITIA: principal, interest, taxes, insurance, and association dues. It is the full monthly payment.
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.
Frequently Asked Questions
Can I get a HELOC on a rental property I own through an LLC?
Not on these lines. Title must be held by you or a revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead, depending on program guidelines.
How much can I borrow against a rental?
On Lendmire’s network, an investment line caps at 70% CLTV, with a maximum line of $500,000 and a $25,000 minimum. Your actual room is 70% of value minus your first mortgage balance. Credit above 700 does not raise the ceiling.
Does the rent count toward qualifying?
Some lenders count part of it, but the file is underwritten on you: credit, DTI, and equity. A DSCR loan works the other way and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Is a HELOC better than a cash-out refinance on a rental?
It depends. A HELOC leaves your first mortgage alone but floats in price and requires personal-income qualification. A DSCR cash-out replaces the first mortgage, tops out around 75% LTV on standard rentals, and is reviewed on rent. The right choice turns on your existing loan, your title, and your leverage need. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Will I need a traditional appraisal?
Usually not on an investment line. Lines at or below $500,000 ordinarily run automated valuation. A higher CLTV may require a second valuation, and you can always request a full appraisal.
Next Steps
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. Programs change, and every file is underwritten individually. This is not a commitment to lend.
Start with your title, your first mortgage balance, and your credit score. Those three facts decide most investment-line files before anything else comes into play.
