The Quick Read: It depends on what you already owe, because the line equals 70% of the property’s value minus every existing lien, capped at $500,000, and it requires a 700 or better credit score with the rental titled in your own name or a revocable living trust. A paid-off rental can use the full 70%. A rental with a mortgage gets only the room left after that mortgage.
- The 70% is a combined test. It counts your first mortgage plus the new line, not 70% on top of your balance.
- The line runs from $25,000 to $500,000. On higher-value rentals, the dollar cap binds before the percentage does.
- Credit scores of 700 and above all face the same ceiling on an investment property.
- A first mortgage at 70% of value or more leaves no room for a line.
- Everything here is subject to lender guidelines and full file review. It is not a commitment to lend.
What Does 70% Loan-to-Value Mean on a HELOC?
A 70% ceiling means your total secured debt against the rental cannot exceed 70% of its value. Lenders call that combined loan-to-value, or CLTV. The first mortgage counts. The new line counts. The leftover 30% of value stays untouched.
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.
This is where most investors misread the number. They hear 70% and picture a line worth 70% of the property. That would only be true if the rental had no mortgage at all.
Our wholesale network sets the ceiling by how the property is occupied. On an investment property, 70% CLTV is the top, with no higher tier. On a primary residence or second home, the ceiling can reach 90% CLTV, but only at a 720 or better credit profile. That extra room does not carry over to rentals.
NerdWallet explains why the gap exists. Lenders see higher default risk on rentals than on the home a borrower lives in, so they offer fewer lines and qualify borrowers more strictly. A lower ceiling is how that caution shows up on the page.
Key Terms Defined
HELOC: a home equity line of credit, a revolving credit line secured by a property you already own.
CLTV (combined loan-to-value): all loans secured by the property, added together, divided by the property’s value.
Lien: a recorded legal claim on the property. Your mortgage is a lien, and so is the HELOC.
First lien and second lien: the order in which claims get paid. A line on a paid-off rental sits in first position. A line behind an existing mortgage sits in second.
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.
Automated valuation: a computer-model estimate of value, used in place of a full appraisal.
DSCR (debt service coverage ratio): monthly rent divided by the full monthly housing payment, which covers principal, interest, taxes, insurance, and any association dues.
The Formula, Step by Step
The maximum line is the smaller of two numbers: the equity room under the 70% test, or the dollar cap. Work through it in this order.
1. Estimate the value. On investment lines, this is usually an automated valuation, with no traditional appraisal. A borrower may still request a full appraisal. NerdWallet notes that some investment lines require multiple appraisals.
2. Multiply the value by 70%. That is your total allowed debt.
3. Subtract every lien. Count the first mortgage and any other recorded loan.
4. Apply the dollar limits. The line cannot be less than $25,000 or more than $500,000.
5. Test the full line limit. The lender measures CLTV on the whole limit, not on what you draw. An unused line still uses up equity.
6. Qualify the borrower. This is a personal-qualification product. Credit, DTI, and equity decide the file. Rent does not.
Step five surprises people. If you want a $100,000 line but plan to draw a small part of it, the full $100,000 still counts against the 70%.
What Does the Room Look Like at Different Mortgage Balances?
The table shows the line as a share of the property’s value. Multiply by your own value to see your number.
| First mortgage (% of value) | Room under 70% CLTV | Line outcome |
|---|---|---|
| None (paid off) | 70% of value | First lien, up to $500,000 |
| 40% | 30% of value | Second lien, up to $500,000 |
| 55% | 15% of value | Second lien, up to $500,000 |
| 65% | 5% of value | Only if room reaches $25,000 |
| 70% or more | None | No line |
The 65% row is a trap for thin-equity rentals. The percentage may be positive, but the dollars can still land below the $25,000 minimum. In that case there is no line to offer.
When the Dollar Cap Beats the Percentage
On a paid-off rental worth more than roughly $714,300, 70% of value already exceeds $500,000. Extra equity adds nothing past that point. The cap wins.
The same break-even works in reverse for owners with large mortgages. A $500,000 first mortgage is fully absorbed by the 70% test until value passes about $714,300. A rental worth less than that leaves no room at all.
Full appraisals are required only on lines above $500,000, and those lines are available only on a primary residence. An investment line therefore commonly closes on an automated valuation instead.
Stress Test: What a Value Drop Does to Your Room
Consider an investor whose first mortgage equals 55% of today’s value. That leaves 15% of the original value available under the 70% ceiling.
Now suppose the property’s value falls 10%. The mortgage balance has not moved, but 70% of the lower value is smaller. The room shrinks from 15% of the original value to about 8%. A modest decline cut the available line by almost half.
This is why timing matters. A line that works on paper in a strong valuation month may not exist after a soft one. If you need the equity for a specific project, run the numbers with a cushion on value instead of the best-case estimate.
Who Qualifies for an Investment Property HELOC?
Qualification is about you first and the property second. Across the wholesale network, the main requirements look like this, subject to lender guidelines and full file review:
- Credit: a 700 minimum on investment lines, with no tier beneath it.
- DTI: a 50% maximum, tested on the interest-only payment at the maximum draw.
- Title: held by you as an individual or by your revocable living trust.
- Property type: single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable ones.
- Not eligible: manufactured homes, co-ops, condotels, log homes, commercial or mixed-use property, and agricultural zoning.
- Exposure: a borrower is limited to three lines in total, and a borrower owning more than 15 financed properties is not eligible.
- Derogatory credit: a bankruptcy needs 4 years of seasoning from discharge or dismissal. A foreclosure needs 7 years, and a short sale or deed-in-lieu needs 4.
- Location: the product is offered only in 16 full-service states, which is narrower than the DSCR footprint of 41 markets, including Washington, D.C.
On DTI, NerdWallet reports market ranges of 40% to 50%, with 50% possibly acceptable when projected rental income is counted. That is a market-wide statement. The network figure is the 50% maximum above.
A property listed for sale, or listed within the past 60 days, is ineligible in several states. If you are weighing a sale, resolve that question before applying.
Why a Higher Credit Score Does Not Raise the Ceiling
Credit above 700 buys eligibility, not leverage. On an investment line, a 700 profile and a 720 profile both top out at 70% CLTV and $500,000. The score is a gate, not a dial.
That surprises borrowers who know how primary-home lines work. There, a 720 profile unlocks the 90% ceiling. On a rental, you cross the 700 gate once and the limit is the same either way.
How the Line Is Structured
Investment lines use one structure: a 5-year interest-only draw period, then a 25-year repayment period where the balance fully amortizes. The line can sit in first or second lien position, depending on whether the rental has a mortgage.
Two features affect planning.
First, at least 75% of the line is drawn at closing. This is not a standby line you open and leave empty. If you want $200,000 available but expect to use only a sliver, this structure is a poor fit.
Second, pricing floats through both the draw and repayment periods and never converts to fixed. Any figure a lender quotes should come with its draw and repayment terms attached.
After closing, you can draw more, with a minimum subsequent draw commonly around $1,000 on programs that state one.
Primary Home, Second Home, or Rental: How the Ceilings Compare
| Occupancy | Max CLTV | Credit needed |
|---|---|---|
| Investment property | 70% | 700 minimum |
| Second home | Up to 90% | 720 for the top tier |
| Primary residence | Up to 90% | 720 for the top tier |
Lines above $500,000 exist only on a primary residence, so that size never applies to a rental. When occupancy is unclear, the lender applies the ceiling for how the property is actually used. A rental does not borrow against a homeowner’s table.
Does the Three-Day Cancel Right Apply to a Rental Line?
Generally, no. The federal right to cancel a home-secured credit transaction within three business days attaches to a security interest in your principal dwelling. The CFPB’s rule text and the eCFR version both frame it around the consumer’s principal dwelling. A rental is not that, and a business-purpose DSCR loan is exempt from Regulation Z’s consumer-credit rules under 12 CFR 1026.3, including the TRID disclosure framework. Do not plan your cash timing around a cancel window that probably does not exist.
HELOC or DSCR Cash-Out: Which Fits the Investor?
The two products answer different questions. A HELOC asks whether you qualify personally. A DSCR cash-out refinance asks whether the property’s rent covers its payment.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Review basis | Credit, DTI, equity | Rent versus payment |
| Max leverage | 70% CLTV, investment property | About 75% LTV, standard rental |
| First mortgage | Stays in place | Replaced by new loan |
| Title | Individual or revocable trust | LLC possible* |
| Seasoning | Not the headline test | About 6 months typical |
*DSCR loans can close in an LLC’s name, subject to lender program eligibility.
Pick the HELOC when your personal profile is strong, your equity needs are modest, and you want to leave a cheap first mortgage alone. Blending a low first mortgage with a pricier second line can still cost more than one refinance, so compare the full package.
Pick DSCR cash-out when the rent is strong but your personal debt load is heavy, or when the rental sits in an LLC. On the network, a cash-out refinance of a standard rental reaches about 75% LTV, and a short-term-rental cash-out tops out at 70%. Across the network, 1.00 coverage is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
One caution about DSCR: clearing 1.00 is not the same as positive cash flow. The ratio compares rent to the housing payment only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. The complete DSCR loans guide covers the full program picture.
Equity does not pool in either product. A HELOC is secured by one property, so equity sitting in your other rentals does not count toward this line.
Common Misconceptions
Myth: 70% means I can borrow 70% of the value. The limit is combined with your existing debt. The line is only what remains after liens.
Myth: I can borrow all my equity. The ceiling stops below 100% of equity. About 30% of value is off-limits.
Myth: A higher score buys more leverage. On investment lines, 700 and 720 reach the same ceiling.
Myth: Every bank offers these. Access is the harder problem than the math. BiggerPockets members describe banks that say they offer home equity lines on primary homes only.
Myth: My rent qualifies me. On a HELOC, your personal file decides. Rent drives DSCR products, not this one.
Myth: My LLC can borrow. An LLC cannot hold title on this line. Irrevocable, blind, and land trusts are out too. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead.
Pre-Application Self-Check
Run these in order before you apply.
1. Estimate the property’s value conservatively, then knock off 10% to see how your room changes. 2. Add up every lien on the property, including any second loan you forgot. 3. Multiply value by 70% and subtract those liens. If the result is under $25,000, stop. 4. Confirm your score is 700 or better. 5. Calculate your DTI with the interest-only payment on the full line, not your planned draw. 6. Check title. If an LLC holds it, plan for a vesting change or a different product. 7. Confirm the property type and state are eligible. 8. Decide whether you can use at least 75% of the line at closing.
Frequently Asked Questions
How much can I borrow on a paid-off rental?
Up to 70% of the property’s value, capped at $500,000. On a rental worth more than roughly $714,300, the cap binds first. The line sits in first lien position, subject to lender guidelines.
Does an undrawn line still count against my 70%?
Yes. The lender measures CLTV on the full line limit. If you open a large line and draw little, the whole limit still uses up equity. Size the line to what you actually plan to use.
Can my LLC take out this line?
No. Title must be held by you personally or by your revocable living trust. A rental in an LLC needs a vesting change, or a DSCR cash-out refinance may fit better, subject to lender program eligibility.
Will a 720 score get me more than a 700 score?
Not on an investment property. Both reach the same 70% CLTV and $500,000 cap. A higher score only helps on primary-residence and second-home lines, where the top tier requires 720.
Does rental income help me qualify?
Not on the standard line. If strong rent is your best asset and personal debt is heavy, a DSCR loan may be the better path.
