The Quick Read: Qualifying means passing two separate reviews: the credit line is approved on you, your equity, and your credit, and then the purchase loan is approved on the new property. Most investors underestimate the second review.
- On this network, an investment property line caps at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit score.
- The line is underwritten on your credit, income, and debts, not on rent.
- An LLC cannot hold title on the property securing the line.
- The purchase loan, often a DSCR loan, is a separate approval with its own leverage, credit, and reserve tests.
- The line’s payment never shows up in the DSCR ratio, but your bank account still pays it.
What “Qualifying” Actually Means
Two lenders, or two programs, look at two different things. The line asks whether you can carry the debt. The purchase loan asks whether the new property carries itself.
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.
| Factor | The HELOC | The purchase loan (DSCR) |
|---|---|---|
| What is underwritten | You, your equity, your credit | The property’s rent against its payment |
| Key ratio | CLTV and debt-to-income | Rent divided by PITIA |
| Income review | Yes, borrower-based | Property-level rental income |
| Collateral | The property securing the line | The property you are buying |
PITIA stands for principal, interest, taxes, insurance, and association dues. A DSCR loan compares monthly rent to that total. Because DSCR loans are designed for non-owner-occupied investment properties and are business-purpose loans, they are reviewed differently from a standard owner-occupied mortgage. You can read the full mechanics in Lendmire’s complete DSCR loans guide.
A line that can fund a down payment does not make the purchase loan automatic. Treat them as two files that must both clear.
Key Terms Defined
HELOC: A home equity line of credit, a revolving loan secured by property you already own.
CLTV: Combined loan-to-value, meaning all loans against a property added together and divided by its value.
Draw period: The stretch when you can borrow from the line, usually with interest-only payments.
DTI: Debt-to-income, your monthly debt payments divided by your monthly income.
DSCR: Debt service coverage ratio, the property’s rent divided by its monthly obligation.
Seasoning: The waiting period a lender wants between events, such as buying a property and borrowing against it.
Why Lenders Make Investment Lines Harder
Investment lines are stricter because the risk is higher. NerdWallet explains that a borrower in trouble is more likely to keep paying their own home than a rental. It also notes that fewer lenders offer these lines and that you can borrow less than you could against a primary home.
Across a wholesale network, that shows up as lower leverage and a higher credit floor. On an investment property, the ceiling is 70% CLTV. On a primary residence, the ceiling reaches 90% CLTV, but only at a 720-or-better credit profile. That gap is why where you borrow matters so much.
What the Line Itself Requires
The line is a borrower product. These are the tests on an investment property, subject to lender guidelines and full file review.
| Factor | Typical investment-line standard |
|---|---|
| Max CLTV | 70% on an investment property |
| Credit score | 700 minimum |
| Line size | $25,000 to $500,000 |
| Debt-to-income | 50% maximum |
| Title | Individual or revocable living trust |
A few details matter more than the table suggests.
Credit above 700 buys eligibility, not leverage. Scores of 700 and 720 both reach 70% CLTV on an investment line. Below 700, there is no tier beneath it.
Debt-to-income is stress-tested. The file is qualified on the interest-only payment calculated as if you had drawn the whole line. A ratio above 45% requires a 680 minimum score, but investment lines already floor at 700.
Title is a hard line. An individual or a revocable living trust can hold title. LLCs, corporations, and partnerships cannot, subject to program terms. A rental already deeded to an LLC needs a vesting change before it can secure a line, or you use a DSCR cash-out refinance instead.
Property type matters. Single-family homes, 2-4 unit properties, townhomes, PUDs, and condos, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not.
History counts. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure follows a 7-year path, and a deed-in-lieu, pre-foreclosure, or short sale follows a 4-year path.
Portfolio size has a ceiling. A borrower is limited to three lines, and anyone with more than 15 financed properties is not eligible.
How Much Line Your Equity Can Support
Start with the cap, then subtract what you already owe. The formula is simple: maximum CLTV, minus your existing mortgage as a percentage of value, equals the share of value you can borrow.
Run it on a rental you own. Say the first mortgage equals 40% of its value. At 70% CLTV on an investment property, you have room for a line worth 30% of the value. If the first mortgage is 55% of value, the room shrinks to 15%.
The $500,000 line limit applies on top of the percentage. Whichever is smaller wins.
Valuation is usually light. Because an investment line cannot exceed $500,000 and full appraisals begin above that, these lines commonly run on an automated valuation with no traditional appraisal. A borrower can still request one.
Lenders also expect you to draw most of the line up front. At least 75% of the line is drawn at closing on this network. Pricing floats during the draw and repayment periods and never converts to fixed. The Consumer Financial Protection Bureau notes that some lines elsewhere in the market allow a fixed-rate conversion, so ask about it before comparing offers.
The structure on an investment line is a 5-year interest-only draw followed by a 25-year fully amortizing repayment. The payment steps up when the draw ends.
What the Purchase Loan Looks At
The second approval runs on the property you want to buy. Most DSCR purchase files across a wholesale network land at 75%-80% LTV, meaning 20%-25% down. Select programs reach 85% LTV on a purchase, which is 15% down, usually with a 700-plus score.
Coverage is where the rent is tested. A 1.00 ratio is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Credit works in tiers too. A 620 floor exists in parts of the network, most programs want around 660, and 700-plus unlocks the strongest leverage. Reserves vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common, and larger loans typically step up from there.
Clearing 1.00 does not mean the property cash flows. Repairs, vacancy, management, utilities, and capital expenses all sit outside the DSCR calculation.
Plan for one more question. Purchase lenders review where your down-payment money comes from, and borrowed funds can be treated differently from program to program. Confirm how your chosen program handles line proceeds before you write an offer, not after.
Which Property Should Secure the Line?
You have two real choices, and a third that sidesteps the line entirely.
| Option | Upside | Risk |
|---|---|---|
| Line on a rental you own | Home stays unpledged | 70% CLTV cap, 700 minimum, personal title only |
| Line on your primary home | Higher ceiling, up to 90% CLTV at 720-plus | Home is exposed if the deal fails |
| DSCR cash-out refinance | Reviewed on the property’s rent | New first-lien terms replace your current loan |
On a rental you own, the line is cheaper in risk terms but tighter in leverage. If the investment fails, the loss stays with the rental.
On your primary home, the ceiling is higher, but the stakes change. Cash drawn on that line sits against the roof over your head. 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.
The third route is a DSCR cash-out refinance. On most files it tops out around 75% LTV, with about 6 months of seasoning as the common expectation.
Lien Order and Other Edge Cases
The general rule is that equity plus credit plus manageable debt gets you a line. Here is where it breaks.
You have no rental yet. A line on a rental requires owning one. First-time investors can only borrow against a primary residence or other real estate they already hold.
The rental is in an LLC. Title in an LLC rules out the line on this network. Some lenders handle entities, so program terms decide this one.
Lien position affects the next loan. A BiggerPockets discussion describes investors being told that a DSCR loan generally cannot sit behind a second lien. The suggested workaround is to complete the DSCR refinance first and add the line afterward. That is investor commentary, not a rule, and it varies by lender.
The property is recently listed. A property listed for sale, or listed within the past 60 days, is ineligible in some states.
Lender appetite is thin. Fewer lenders write investment lines at all, which is why many investors default to a refinance.
Payment shock arrives later. The draw period can last years, as the CFPB’s example of 10 years shows. When it ends, the payment steps up. The CFPB booklet also explains that variable rates track a public index and that variable-rate plans secured by a dwelling must carry a cap by law.
A Step-by-Step Walk Through
Here is the sequence a broker would run with you.
1. Screen yourself first. Check credit against the 700 floor, your DTI against 50%, and the property type and title.
2. Run the equity math. Subtract your existing mortgage from the 70% CLTV cap on an investment property.
3. Choose the collateral. Decide whether a rental or your primary home secures the line.
4. Gather documents. Expect income documents, a current credit report, proof of insurance, and, for a rental, lease agreements. NerdWallet adds that lenders may ask for reserves, proof of long-term tenants, or more than one appraisal.
5. Apply for the line. Credit reports must be no more than 90 days old at closing.
6. Pre-clear the purchase loan. Confirm leverage, coverage, reserves, and how the program treats borrowed down-payment funds.
7. Draw and buy. Fund the down payment and closing costs, then move on the property.
A worked example shows how the pieces fit. Say you buy a rental with 20% down at 80% LTV. The line supplies that down payment, and the new property’s rent covers its full PITIA at roughly 1.2x. The DSCR looks healthy. But the line’s own interest-only payment is not in that ratio, so your personal budget has to absorb it. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Who This Fits
A line suits an owner with a lot of equity, strong credit, and moderate existing debt who wants a down-payment bridge. It works poorly for a portfolio investor stacking personal debt against the 50% DTI limit.
DSCR underwriting runs property by property, so it scales better as the portfolio grows.

Frequently Asked Questions
Can I use a HELOC as the whole purchase price?
Rarely. An investment property line caps at 70% CLTV and $500,000, so it covers a piece of the price. The purchase loan normally supplies the rest, and its lender reviews the source of your down-payment funds.
Do I need a rental already?
For a line on a rental, yes, because the equity has to exist. If you own only your home, the line goes on that property instead. A primary residence line can reach 90% CLTV, but only at a 720-or-better credit profile.
Can my LLC borrow against its rental?
Not on this network. Title must sit with an individual or a revocable living trust, so a property in an LLC needs a vesting change first. The other path is a DSCR cash-out refinance, subject to program terms.
Does rent count toward qualifying?
The line is reviewed on credit, income, and debts, not rent. The purchase loan is the one that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Is a HELOC available everywhere?
No. Eligibility also depends on the property, the equity, and your credit profile.
