The Quick Read: Qualifying for a line secured by the rental itself comes down to five tests: a credit score of at least 700, total borrowing against the property at or below 70% of its value, a debt-to-income ratio of 50% or less, title held in your own name or a revocable trust, and an eligible property type. These are typical standards across the select wholesale lenders Lendmire works with, and every file is subject to lender guidelines and full review.
- Credit: 700 is a hard floor for a line on an investment property, and 720 buys no extra leverage.
- Leverage: an investment-property line tops out at 70% combined loan-to-value (CLTV), with a maximum line of $500,000.
- Title: an LLC cannot hold title on these lines, which is the sharpest difference from a DSCR loan.
- Structure: a 5-year interest-only draw, then 25 years of repayment, with at least 75% of the line drawn at closing.
- Fallback: if the test fails, a DSCR cash-out refinance qualifies the property on its own rent instead of your personal debt load.
What “On an Investment Home Instead” Means
A home equity line of credit (HELOC) can be secured by one of two properties. It can sit on your rental, or it can sit on the home you live in. Choosing the rental keeps your own house out of the deal. Choosing your primary home usually gets you more room to borrow.
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.
That tradeoff is the whole decision. Here is how the two options compare on the network Lendmire brokers through.
| Factor | Line on the rental | Line on your primary home |
|---|---|---|
| Property at risk | The rental | Your own home |
| Top CLTV | 70% | Up to 90% (720+ credit only) |
| Credit floor | 700 | Lower tiers exist |
| Maximum line | $500,000 | Up to $750,000 |
The gap in leverage is real. A primary-residence line reaches 90% CLTV only at a 720-or-better credit profile. The investment tier stops at 70% no matter how strong your credit is. Expect to qualify for less cash on a rental, in exchange for keeping the family home clear of the debt.
Key Terms Defined
HELOC: a revolving credit line secured by a property, where you borrow against your equity in stages instead of taking one lump sum.
Equity: the property’s value minus what you owe on it.
Combined loan-to-value (CLTV): your first mortgage plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow from the line and pay only interest.
Repayment period: the stretch after the draw ends, when you pay down principal and interest until the balance is gone.
Lien position: where your loan stands in line for repayment if the property is sold or foreclosed. First lien gets paid first. Second lien gets paid after.
Vesting: the legal name that holds title to the property, such as you personally, a trust, or an LLC.
Automated valuation: a computer-generated value estimate used in place of a full appraisal.
DSCR: debt service coverage ratio, meaning the property’s rent divided by its monthly housing obligation (principal, interest, taxes, insurance, and any HOA dues).
How Underwriting Treats a Rental Line, Step by Step
An investment-property line is underwritten like a second mortgage on a business asset. The lender checks equity first, then credit and debt, then income, then title and property type. A miss on any one step ends the file.
Many investors assume the process mirrors a home equity line on a primary residence. It does not. Large retail lenders often decline rental collateral altogether, and NerdWallet notes that not every lender offers these lines and that qualification is strict. A wholesale network helps here because you see more guidelines at once.
Step 1: Equity. The lender caps combined debt on the property at 70% CLTV for an investment line. Experian, for example, cites a typical 80% limit and a 720 credit score, plus at least 20% equity left after the line is fully drawn. The network figure for an investment-property line is 70% CLTV at 700 or better, and that is the number to plan around. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Step 2: Credit. The floor is 700, and 720 does not raise the leverage ceiling. The lender pulls one score, keyed to the primary wage earner. The report must be no more than 90 days old at closing, and rescoring is not available. Past credit events matter as well. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4.
Step 3: Debt-to-income. The ceiling is 50%. Underwriters review your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. That detail surprises people. Every other mortgage you carry counts against the ratio, including mortgages on other rentals.
Step 4: Income documents. A personal-income line is underwritten on documented income under the applicable program. Lenders commonly ask for leases, a rent roll, and proof of existing mortgage payments on the rental. If you qualify with business bank statements, the deposit analysis needs a 680 minimum. Investment lines already floor at 700, so that test is never the one that stops you.
Step 5: Valuation. Because an investment line caps at $500,000, it falls in the automated valuation lane. Most such lines close with no traditional appraisal. A higher CLTV can trigger a secondary valuation, and you can always ask for a full appraisal.
Step 6: Title and property. The lender confirms who holds title and that the property type is eligible. Both are covered in the edge-case section below.
How to Calculate Your Maximum Line
Your maximum line is your property’s value multiplied by 70%, minus your first-mortgage balance, then capped at $500,000. Run it in percentages of value first. The calculator on this page can convert the percentages to dollars.
| First mortgage as % of value | Room under the 70% CLTV ceiling |
|---|---|
| 40% | 30% of value |
| 50% | 20% of value |
| 60% | 10% of value |
| 70% or more | None |
Picture an investor whose first mortgage equals 50% of the rental’s value. The ceiling leaves 20% of value to borrow against. If the rental is valued very high, the $500,000 maximum line can bind before the 70% ceiling does. If it is valued modestly, the 70% ceiling binds first.
Two practical limits shape the outcome. The minimum line is $25,000, so thin room under the ceiling can mean no product at all. And since at least 75% of the line is drawn at closing, you will carry most of the balance from day one. This is not a standby line you open and leave idle.
Experian’s guidance to keep a cushion of equity is sensible for a different reason. A lender can freeze or reduce a line if the property’s value falls. Plan as if the full line may someday be unavailable to redraw.
How the Line Works After Approval
Once approved, an investment-property line runs on one structure only. It has a 5-year interest-only draw period, followed by a 25-year fully amortizing repayment period. The line can sit in first or second lien position. Pricing floats during both the draw and the repayment period, and it never converts to a fixed structure.
The Federal Trade Commission says HELOC pricing is typically variable and that the amount you can borrow depends on your income, credit history, and the property’s market value. Both points hold here. Your monthly cost can move for the life of the line.
Compare that with the market. The network’s investment structure is shorter: 5 years of draw, then 25 years of repayment. Treat any longer draw you see online as a different product.
Lien position matters if you already have a mortgage on the rental. A second-lien line sits behind that mortgage, and some lenders will only lend in first position on a rental. Lendmire’s piece How to Qualify for an Investment Property HELOC With an Existing Second Lien on Your Home covers that situation in detail.
Where the General Rule Breaks
The five core tests apply to most files. Several edge cases decide the rest, and they are the ones that surprise borrowers most often.
An LLC cannot hold title
Fee simple or leasehold title must sit with you personally or with a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. Many investors deed rentals into an LLC for liability reasons. If yours is already deeded that way, the line needs a vesting change first, or you move to a DSCR cash-out refinance instead.
Property type
Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums (including non-warrantable condos) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agricultural zoning are not offered. A rental in a condo-hotel or on agricultural land stops at this step no matter how strong your credit is.
Listed for sale
A property that is listed for sale, or was listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington. Lendmire’s piece How to Qualify for an Investment Property HELOC With the Home Listed for Sale Soon explains how to plan around that.
Portfolio limits
A borrower can hold at most three lines. Combined exposure across those lines is capped by program, between $750,000 and $2,000,000. A borrower who owns more than 15 financed properties is not eligible. Larger portfolios usually belong in DSCR territory, where the property carries the file.
Availability
This product is available only in Lendmire’s 16 full-service states: Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia, and Washington. That is narrower than the 41-market footprint for DSCR investor loans.
Which Collateral Should You Use?
Use the rental when you want to keep your home out of the deal. Use your primary home when you need more cash than the 70% ceiling allows and you accept the risk. Match the choice to what you are funding.
| Your situation | Likely better fit | Why |
|---|---|---|
| Repairs on the rental | Line on the rental | Debt stays with the asset |
| Down payment on the next rental | Either | Compare the room under each ceiling |
| Rental held in an LLC | DSCR cash-out | LLC title is not allowed |
| Thin equity on the rental | Line on primary home | Higher ceiling, more room |
| Credit between 620 and 699 | DSCR cash-out | Below the 700 line floor |
The down-payment case deserves a second look. A line used for a purchase creates two approvals. The line gets underwritten on your credit, debt, and equity. The new purchase loan is then underwritten on its own terms. Because the HELOC payment counts against your debt-to-income ratio, it can make the second approval harder. If the next purchase is a DSCR loan, that loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, so your personal debt-to-income ratio matters less there.
Putting the line on your primary home is the most direct way to reach the cash. The stronger play for many investors is the rental line, though, because losing a rental is a business setback. Losing the house is a different kind of problem. That is the real tradeoff, and it is a genuine toss-up for investors with one rental and a lot of home equity.
If You Don’t Qualify
A failed test points to a specific fallback. Most failures on rental lines come from LLC title, a credit score under 700, or a debt-to-income ratio that is already stretched.
| Failed test | Practical fallback |
|---|---|
| Credit under 700 | DSCR cash-out refinance |
| Debt-to-income over 50% | DSCR cash-out refinance |
| LLC title | Vesting change, or DSCR cash-out |
| Over 15 financed properties | DSCR cash-out |
| Not enough equity under 70% | Wait, or use primary-home equity |
A DSCR cash-out refinance replaces your first mortgage and qualifies primarily on the property’s rent covering its payment, subject to lender guidelines. Across the network it typically tops out around 75% LTV on a standard-rental cash-out refinance, and about 70% on short-term-rental collateral. Roughly 6 months of seasoning is the common expectation. Loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders. Credit floors reach down to 620 in parts of the network, most programs want about 660, and 700 or better unlocks the strongest leverage.
Coverage works as a separate test. 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. Reserves vary by lender, leverage, and loan size, and about 6 months is a common starting point. LLC-titled borrowers can use these loans, subject to program terms.
Be clear on what a coverage ratio does not tell you. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. The trade for qualifying on the property is that you give up your current first mortgage. For many investors that is a real cost. Lendmire’s complete DSCR loans guide walks through that comparison in full.
What Can Go Wrong
Three risks are worth pricing in. The first is that your carrying cost can move, since pricing floats across the whole life of the line. The second is that a lender can reduce or freeze the line after a value decline, as noted earlier. The third is collateral exposure. A line on the rental is a lien against that property, and missing payments can put it at risk of foreclosure. Experian flags that second-mortgage risk specifically.
Pre-Application Readiness Checklist
- Confirm title is in your name or a revocable trust, not an LLC.
- Check your credit score against the 700 floor, and confirm the report will be under 90 days old at closing.
- Add up every mortgage payment you carry and test the total against 50% of income.
- Calculate your first mortgage as a percentage of the property’s value.
- Gather leases and a current rent roll for the property.
- Confirm the property type is eligible and that it is not listed for sale.
- Count your financed properties and any other lines you already hold.
- Review your state against the 16 full-service states.
Frequently Asked Questions
Can I get a HELOC on a rental if I only own one investment property?
Yes, if you pass the equity, credit, and debt-to-income tests. A single rental can qualify at 70% CLTV with a credit score of 700 or better. The three-line and 15-property limits only matter once your portfolio grows, so a one-property investor rarely hits them. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Does a credit score above 700 raise my borrowing limit on a rental?
No. The investment tier is a two-tier table where 700 and 720 both reach the same 70% CLTV, with a maximum line of $500,000. Extra credit strength buys eligibility, not leverage. It does help on other products, such as primary-residence lines, where 90% CLTV is reachable at 720 or better. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Can I use a rental HELOC to buy another rental?
Often, yes, but the purchase lender will count the new line’s payment in your debt-to-income ratio. That can narrow your options. If the next property is a DSCR purchase, it qualifies primarily on its own rent covering the payment, subject to lender guidelines, which lessens that problem. Purchases typically run 75% to 80% LTV on most files.
What happens if my property is held in an LLC?
An LLC cannot hold title on these lines. You can move title into your own name or a revocable trust before applying, or you can skip the line and use a DSCR cash-out refinance, which accepts LLC-titled properties subject to program terms. Talk to an attorney before changing title, since it can affect liability protection.
Will a full appraisal be required?
Usually not. Lines up to $500,000, which covers every investment-property line, ordinarily run on automated valuation. A higher CLTV can add a secondary valuation, and you can request a full appraisal at any time if you want one.
