Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
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 Quick Read: A 660 score clears the 600 floor on a line secured by your primary home, but it falls 40 points short of the 700 minimum on a line secured directly by a rental, so the property you pledge decides the outcome, not the rent. These lines are underwritten on you, not on the property’s income. Four facts follow.
- A line secured by a rental needs a 700 minimum score and tops out at 70% CLTV (combined loan-to-value) on an investment property, up to $500,000.
- A line secured by your primary home has a 600 floor, so 660 clears the credit test there, but the home carries the risk.
- Moving from 660 to 700 or 720 on a rental line buys eligibility, not more leverage, because both tiers stop at the same 70% CLTV.
- A DSCR cash-out refinance is the 660-friendly alternative, because it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
What an Investment Property HELOC Actually Is
An investment property HELOC is a revolving credit line secured by real estate. You draw what you need, pay on the balance, and the remaining room stays available during the draw period. It is not a purchase loan. A HELOC cannot buy a property you do not own. It funds a down payment, a renovation, or reserves on a separate transaction.
On the programs Lendmire brokers, the line can sit in first or second lien position. It is a standalone product. You do not need to refinance your existing mortgage to open one.
The line is not a business loan in disguise, either. It runs on the same logic as a home equity line: your credit, your debts, your housing history, and how much equity is left after your existing liens.
Where a 660 Score Sits
A 660 is a credit score in the Fair range, which is not the same as a bad one. MyFICO places 580 to 669 in the Fair band and 670 to 739 in the Good band. That puts 660 at the top of Fair, nine points under Good. The same page notes that many lenders still approve loans in the Fair band.
The score model matters. Experian notes that VantageScore uses a different Fair band, 601 to 660. A 660 on one model is not the same standing as a 660 on another. The programs in the wholesale network use a single-bureau score tied to the primary wage earner. The report must be no more than 90 days old at closing, and rescores are not available. So the score in your banking app may not be the score the lender sees.
Here is how a 660 stacks up against the two collateral choices:
| Factor | Line on a rental | Line on your primary home |
|---|---|---|
| Minimum credit score | 700 (hard floor) | 600 program floor |
| Does 660 clear it? | No | Yes |
| Max CLTV | 70% | 90% only at 720+ |
| Line size | $25,000 to $500,000 | Up to $750,000 |
At 660 you sit below the top leverage tier on a primary home. The 90% ceiling exists only at a 720-or-better credit profile. Your actual ceiling depends on your tier and the line size. Treat 90% as a number for stronger files.
NerdWallet reports that lenders typically want a 720 or better score for an investment property line, versus roughly 620 for a primary home. On the network Lendmire works with, the investment line floor is 700, with no tier beneath it.
How Underwriting Treats the File, Step by Step
Here is the sequence a rental-secured or home-secured line follows.
1. Collateral choice. The line is secured by either the rental or your primary home. At 660, only the primary-home route clears the credit floor.
2. Credit pull. The lender pulls a single-bureau score, verifies income and employment, and reviews your housing history. The report must be no more than 90 days old at closing.
3. Debt-to-income test. The program maximum DTI is 50%, but that figure is not available at every score. For profiles from 600 to 679, the cap drops to 45%, and a ratio above 45% requires a 680 minimum. The payment is calculated as interest-only on the maximum draw, not on what you plan to borrow.
4. CLTV math. Your usable room is the property’s value times the CLTV cap, minus every lien already on it.
5. Valuation. A line at or below $500,000 ordinarily runs an automated valuation, with no traditional appraisal. A higher CLTV may call for a secondary valuation. You can also ask for a full appraisal. A full appraisal is required on any line above $500,000.
6. Draw at closing. At least 75% of the line is drawn at closing, so a borrower who expected to take money only as needed should plan for that.
Step three deserves the closest look at a 660 score. The DTI test uses the full-draw payment, so a borrower with a car loan, a mortgage, and student debt can hit the 45% cap before the credit score even matters.
Notice what is missing from the list. Rent is not tested. A vacant or between-tenant rental can still qualify, because the file is built on the person. Rent that comfortably covers your mortgage does nothing for a HELOC application.
The Two Structures Behind the Line
Lendmire brokers HELOCs through two wholesale programs. One is built for higher leverage, and the other for a longer interest-only runway. Each applies its own terms, so a quote always carries its own program’s structure.
On a primary residence or second home, there are two draw structures. One is a 3-year interest-only draw followed by a 17-year repayment. The other is a 5-year interest-only draw followed by a 25-year repayment. Investment lines run the 5-year draw and 25-year repayment structure only.
Pricing floats through both the draw and repayment periods and never converts to a fixed structure. In plain terms, your payment can move for the entire life of the line. During the draw period you owe interest only. When repayment starts, the payment steps up because principal is added.
The CFPB’s HELOC booklet adds two points that matter for rental investors. Lenders can reduce a credit line if the home’s value declines, and a sale generally requires the line to be paid off. Do not plan a renovation around cash you have not yet drawn.
Minimum subsequent draws after closing are $1,000, with Texas at $4,000 under the longer-runway program. The higher-leverage program does not state subsequent-draw minimums.
Where the General Rule Breaks
The rule is simple: 700 for a rental line, 600 for a primary line, 70% CLTV on the rental. These edge cases bend it.
Occupancy at application drives the lane. A property’s status at application decides which tier applies. What you do with it afterward does not. Some investors are tempted to describe a rental as a primary residence to reach the lower score floor. That is occupancy misrepresentation, and it is not a workaround. Pledge the property for what it is.
Title decides eligibility regardless of credit. The line must be held by you as an individual or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If your rental is already deeded to an LLC, you need a vesting change or a different product. A DSCR cash-out refinance can allow entity vesting, subject to program eligibility.
A thin equity position closes the door. A first-time landlord with one recently purchased rental often has little usable room under a 70% CLTV cap. If your first mortgage is already 50% of the value, the cap leaves room worth 20% of value. If the mortgage is at 70% or higher, there is nothing left.
Property type can end the application. The programs accept single-family homes, 2 to 4 units (with a 640 minimum on the longer-runway program), PUDs, townhomes, and condominiums, including non-warrantable ones. They do not offer lines on manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, or agricultural zoning.
Exposure limits cap a growing portfolio. 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 owning more than 15 financed properties is not eligible.
Past credit events follow set seasoning. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year path for a foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale.
Geography narrows the field. Lendmire arranges HELOCs in 16 full-service states, which is narrower than its 41-market DSCR footprint, Washington, D.C. included. Many banks also simply do not write lines on rentals, so a retail lender’s no does not tell you much.
What the Decision Looks Like at 660
Picture an investor with a 660 score who owns two rentals and a primary home. Her first mortgage on the primary is moderate, and one rental carries a first mortgage near half its value. She wants cash for a down payment on the next property.
The rental-secured line is out. Her score sits 40 points under the 700 floor. The primary-home line clears the 600 floor, but two things limit it. Her CLTV ceiling is lower than the 90% maximum, which exists only at a 720-or-better credit profile, and her DTI is capped at 45% at her score. The payment on a full draw may push her over.
She has three realistic paths.
| Path | Secured by | Underwritten on | Fits when |
|---|---|---|---|
| Rental HELOC | The rental | You (700+ score) | Score is 700+, equity is ample |
| Primary-home HELOC | Your home | You (600 floor) | You accept risk to your home |
| DSCR cash-out refinance | The rental | Property rent coverage | Rent is strong, personal DTI is tight |
The primary-home line works, with a real tradeoff. The risk lands on the house you live in rather than the rental. Whether that is acceptable is a personal call, and it is the main reason some investors pass on this path.
Waiting can be a legitimate plan. Moving from 660 to 700 opens the rental-secured line, though not more leverage. Use the time to pay down revolving balances and keep housing payments clean. Do not apply repeatedly, because each pull is a hard inquiry.
A DSCR cash-out refinance shifts the question. The property’s rent covers the payment, instead of your personal income covering a theoretical draw. Minimum scores vary by lender, and most programs want around 660, while 700 or better unlocks the strongest leverage tiers. Cash-out refinance tops out around 75% LTV on a standard rental, and about 6 months of seasoning is the common expectation. Reserves vary by lender, leverage, and loan size, and commonly run around 6 months of PITIA (principal, interest, taxes, insurance, and any HOA dues).
Coverage is the other test. A 1.00 DSCR is where select programs start, and stronger ratios earn better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 does not mean positive cash flow. DSCR compares rent to PITIA only, and repairs, vacancy, management, and capex sit outside the calculation.
The tradeoff is cost and structure. A cash-out refinance replaces your existing first mortgage, while a HELOC leaves it in place. That matters if your current first mortgage is one you want to keep. Lendmire’s piece DSCR HELOC vs DSCR Cash-Out Refinance For Investment Property Credit Score Under 660 walks through that tradeoff in more detail. The complete DSCR loans guide covers how coverage, credit, and leverage work together.
A practical observation from files like this: the strongest applications clear both tests, enough equity and enough rental coverage. A larger down payment or more equity lowers the payment and can lift coverage, but it never erases a credit floor, a leverage cap, a reserve rule, or a property type that is not offered.
One more point on the funds themselves. A HELOC is a capital-sourcing tool, so the cash goes toward a down payment on a separate purchase or toward repairs on a property you already own. Drawing against your own home to fund a rental means the home secures that debt whether or not the rental performs.
A Sequenced Plan Before You Apply
1. Confirm the occupancy you will pledge and whether your name, a revocable trust, or an LLC holds title. 2. Check your score and your balances. Reduce revolving debt if your DTI is near 45%. 3. Estimate your equity: value times the CLTV cap, minus every existing lien. 4. Test your DTI at the full-draw interest-only payment, not the amount you plan to borrow. 5. Compare the primary-home line, a rental line (if you reach 700), and a DSCR cash-out refinance on the same property.
A HELOC and a DSCR loan are different products for different borrower profiles. Equity pulls with a clean personal profile lean HELOC. Rent-covered deals with a thinner personal profile lean DSCR.

Draw period: The stretch when you can borrow from the line and pay interest only, before repayment begins.
DTI (debt-to-income): Your monthly debt payments divided by your monthly income, tested here on the full-draw interest-only payment.
DSCR (debt service coverage ratio): A property’s monthly rent divided by its monthly payment of principal, interest, taxes, insurance, and any HOA dues.
Seasoning: The waiting period a lender wants after an event, such as buying a property or a bankruptcy discharge, before it counts as settled.
Vesting: How title to the property is held, such as an individual, a revocable trust, or an LLC.
Frequently Asked Questions
Can you get a HELOC on a rental property with a 660 credit score?
Not directly on a rental through the network Lendmire works with, because that line has a 700 minimum. A 660 does clear the 600 floor on a line secured by your primary residence. Your DTI is capped at 45% at that score, and your CLTV ceiling sits below the top tier. Every file is reviewed individually and is subject to lender guidelines.
Does rental income help me qualify for the line?
No. These lines are underwritten on your credit, DTI, and housing history. Rent does not enter the calculation, and a vacant rental can still qualify. Rent matters in a DSCR loan, where qualification runs primarily on the property’s rental income covering the payment.
Will a higher score give me more leverage on a rental line?
No. Both the 700 and 720 tiers reach the same 70% CLTV on an investment property, up to $500,000. A higher score adds eligibility, not leverage. Market surveys cited by NerdWallet report that lenders generally want an even higher score for these lines, so the network’s 700 floor is a program figure, not an industry standard.
Can an LLC own the property behind the line?
No. Only an individual or an inter vivos revocable living trust can hold title. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance, where entity vesting may be available subject to program eligibility.
What happens if I am declined?
Find out which test failed: score, DTI, equity, title, or property type. Each has a different fix. Waiting to raise your score and lower debts can help, and a DSCR cash-out refinance may suit a rental with strong coverage.
