The Quick Read: Usually, you can borrow up to 70% of an investment property’s value on this kind of line, minus every existing lien and counting the full credit limit, with a $500,000 maximum, subject to lender guidelines. The lender qualifies you, not the rent.
- The ceiling: On an investment property, the network tops out at 70% combined loan-to-value (CLTV). Credit above the 700 floor does not raise it.
- The size range: Investment lines run from $25,000 to $500,000. Tiny leftover equity can leave you below the minimum.
- The test: The lender counts the whole line, not just what you draw.
- The catch: Title must sit in your name or a revocable trust. An LLC cannot hold it.
Plenty of homeowners wonder how much they can borrow once a rental’s value climbs. Equity has built up, and the next purchase or repair needs cash. This guide shows how the number is built, what shrinks it, and when a different loan makes more sense.
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.
How Much Can You Borrow on an Investment Property HELOC?
The formula is simple. Maximum line = (property value × allowed CLTV) − all existing liens. Then the dollar cap, the program minimum, and your personal qualification can each shrink that result.
CLTV stands for combined loan-to-value. It adds every loan secured by the property, then compares the total to the appraised value. The proposed line counts in full.
Across the wholesale network Lendmire works with, investment-property lines carry a 70% CLTV ceiling. Primary residences and second homes can reach 90% CLTV, but only with a 720 or better credit profile. Do not carry that 90% figure over to a rental. It does not apply.
Market surveys paint a rosier picture. Experian reports that investment-property HELOCs are typically capped at 80% CLTV. That is a market-wide figure. On Lendmire’s network, an investment property line stops at 70%.
Worked Examples: Three Ways the Number Comes Out
Here are three scenarios, all expressed as a share of the property’s value. Run your own numbers the same way.
The comfortable case. Your first mortgage equals 40% of the value. The 70% ceiling leaves room for a line worth up to 30% of the value. On a modest rental, that equity result is the binding limit.
The thin-equity case. Your first mortgage equals 65% of the value. Only 5% of the value is left under the ceiling. If that slice is worth less than the $25,000 program minimum, no line is possible. Adding a second lien or a larger balance only makes it worse.
The cap-bound case. Your rental is worth a lot and the mortgage is small, so equity is not the problem. The $500,000 maximum binds first. An investment line cannot go higher, however much equity you hold.
Now the free-and-clear rental. With no first mortgage, you still face the same 70% ceiling. Paying the property off removes a lien from the math but not the cap.
What Actually Limits Your Line
Several limits work at once, and the lowest one wins.
| Limit | Investment property line | What it means |
|---|---|---|
| CLTV ceiling | 70% | Caps total liens plus the line |
| Maximum line | $500,000 | Binds on high-value properties |
| Minimum line | $25,000 | Thin equity can fall below it |
| Credit floor | 700 | 700 and 720 reach the same 70% |
| Debt-to-income | Up to 50% | Tested on interest-only payment at full draw |
Credit is the one that surprises people. On investment property, 720 and 700 reach the same 70% CLTV. A higher score buys eligibility, not extra leverage.
The debt-to-income test (DTI) is the other personal limit. The lender measures it on the interest-only payment at the maximum draw, not at the amount you plan to use. An investor with several mortgages and a modest salary can pass the equity test and still fail this one.
Does Rental Income Count?
Not on this product. A borrower-qualified line is underwritten on your credit, income, and debts. The property’s rent does not set the limit.
Credit history carries rules too. On investment files, a foreclosure needs 7 years of seasoning and a short sale or deed-in-lieu needs 4. A bankruptcy needs 4 years from discharge or dismissal.
If personal DTI is what holds you back, a rent-based loan changes the test. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR means debt service coverage ratio: monthly rent divided by the full monthly payment, covering principal, interest, taxes, insurance, and any association dues. The complete DSCR loans guide walks through that math.
How the Mechanics Work Step by Step
1. Value is set. Lines at or below $500,000 ordinarily run on an automated valuation, which means most investment lines close without a traditional appraisal. A higher CLTV may need a second valuation, and you can always request a full appraisal.
2. Existing liens are added. That means the first mortgage and any junior lien.
3. The full proposed line is added. Drawing less does not help the test.
4. The total is compared to the 70% ceiling. What is left is the maximum line.
5. The cap, the minimum, and your personal profile are applied. Your personal profile, not the rent, decides whether you qualify.
The CFPB booklet on home equity lines describes the same standard sizing method. A lender takes a percentage of the home’s value, then subtracts what you owe. The BiggerPockets blog walks through the same arithmetic on a sample rental.
The paperwork is short. Expect the current first-mortgage statement, the insurance declaration, and the vesting deed showing how title is held.
How the Draw and Repayment Phases Work
The CFPB defines a HELOC as an open-end line you can borrow against repeatedly. It also describes a draw period followed by a repayment period.
On an investment property, the network runs one structure: a 5-year interest-only draw period, then 25 years of fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats the whole way and never converts to fixed.
That 75% draw matters for planning. This is not a line you open and leave empty. Plan for most of it to be in use from day one, and size the line to a real need.
Who Can Hold Title?
Title must be held by you individually or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
This is the sharpest difference from a DSCR loan. If your rental already sits in an LLC, you have two paths. You can change the vesting, or you can use a DSCR cash-out refinance, where LLC title may be accepted subject to lender program eligibility.
Which Properties and Borrowers Are Eligible?
Eligible property types include:
- Single-family homes
- 2-4 unit properties
- PUDs and townhomes
- Condos, including non-warrantable ones
Manufactured homes, co-ops, condotels, log homes, commercial or mixed-use properties, and agricultural zoning are not offered.
Borrower limits also apply. A borrower is limited to three lines, and owning more than 15 financed properties makes you ineligible. In Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington, a property listed for sale, or listed within the past 60 days, is ineligible.
Availability is narrow. These lines are offered in 16 states, which is far fewer than the 41-market DSCR footprint. That is one reason investors often hear that few lenders offer them. The White Coat Investor makes the same point and notes that these lines are often harder to qualify for than a primary-residence line.
Which Property Should Secure the Line?
Homeowners often have a choice: put the line on the rental, put it on the home they live in, or skip the line and refinance. Each has different limits.
| Factor | HELOC on the rental | HELOC on your home | DSCR cash-out refinance |
|---|---|---|---|
| Ceiling | 70% CLTV | Up to 90% CLTV at 720+ | Around 75% LTV on a standard rental |
| Reviewed on | You | You | Property rent, primarily |
| Title | Individual or trust | Individual or trust | LLC possible, per program |
| Existing first mortgage | Stays | Stays | Replaced |
A line on your own home can reach a higher ceiling, but your home becomes the collateral. If you can’t repay, you could lose that home. The CFPB warns of exactly that risk. Some line agreements also restrict renting out the home, so read the terms before using it that way.
The BiggerPockets blog notes that HELOCs suit BRRRR investors, who repay the line at refinance and repeat the process. The tradeoff is that the leverage ceiling on a rental line is lower than on a primary line.
When a DSCR Cash-Out Refinance Makes More Sense
A HELOC keeps your first mortgage and adds a second lien. A cash-out refinance replaces the first mortgage with one larger loan. That reprices the whole balance, but it handles bigger sums and LLC title.
Across the network, a cash-out refinance on a standard rental tops out around 75% LTV. About 6 months of seasoning is the common expectation, and standard loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Stronger credit helps. Most programs want around 660, a 620 floor exists in parts of the network, and 700 or better unlocks the strongest leverage.
On coverage, 1.00 is where many select programs start. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted. Stronger ratios generally open better pricing and leverage. Reserves vary by lender, leverage, and loan size, and commonly run around 6 months of PITIA (principal, interest, taxes, insurance, and association dues).
One caution: clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Also, a cash-out raises your loan balance, which lowers your coverage ratio on that property.
What Can Go Wrong
The risks are concrete, so read them before you draw.
- Foreclosure on the rental. Experian notes that default can mean foreclosure on the investment property.
- Line freezes. The CFPB booklet explains that lenders can freeze or reduce a line if the home’s value falls.
- A floating payment. Pricing floats and never converts to fixed. The payment can change over the life of the line.
- Using a HELOC to buy the next property. A line only frees cash. It does not make the next purchase qualify by itself.
Key Terms Defined
CLTV (combined loan-to-value): All loans secured by the property added together, divided by its appraised value.
Draw period: The stretch when you can borrow from the line and, on investment lines, pay interest only.
Repayment period: The stretch after the draw period, when the balance amortizes and you pay principal and interest.
Automated valuation: A computer-generated value estimate used in place of a traditional appraisal on smaller lines.
Vesting: How title to the property is held, such as individually, in a revocable trust, or in an LLC.
DSCR: A ratio comparing a property’s rent to its full monthly payment.
Frequently Asked Questions
Can I borrow more than 70% if my credit is excellent?
Not on an investment property. A 700 and a 720 credit profile reach the same 70% CLTV, so a higher score buys eligibility rather than leverage. The 90% ceiling exists only on primary residences and second homes, and only at 720 or better.
Does the lender count only what I draw?
No. The lender counts the full credit limit in the CLTV test, whether or not you draw it. Drawing $50,000 on a larger line does not make the test easier.
Can my LLC take out this HELOC?
No. For a property already in an LLC, change the vesting or look at a DSCR cash-out refinance, where LLC title may be accepted per program terms.
What if my leftover equity is small?
Then the line may not exist. The program minimum is $25,000, so if 70% of value minus your liens leaves less than that, you fall below the floor. A smaller first mortgage or a rent-based cash-out may fit better.
Do I need an appraisal?
Usually not. Investment lines cap at $500,000, so they typically use an automated valuation. A higher CLTV may require a secondary valuation, and you can request a full appraisal if you prefer one.
Next Step
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. For a rental sitting in an LLC or one that qualifies better on rent than on your personal income, a DSCR cash-out refinance may be the cleaner comparison.
