The Quick Read: You get one by applying for a separate home equity line (HELOC) that sits behind your existing loan as a second lien, and the lender pool is small: your current bank, credit unions and regional banks, and brokers who place files with wholesale lenders, each with its own limits on rentals, leverage, and title. Here is what matters most:
- The first mortgage stays untouched. The new line is a second lien behind it.
- Across Lendmire’s wholesale network, an investment-property line tops out at 70% combined loan-to-value (CLTV) and $500,000, subject to lender guidelines.
- Most lenders want the rental titled in your own name or a living trust. An LLC usually blocks the line.
- A cash-out refinance or a DSCR cash-out is the fallback when the line does not fit.
Why Is a Rental HELOC Harder to Find Than a Home HELOC?
Lenders see more default risk on a rental than on the home you live in, so fewer of them offer the product. NerdWallet says the lender pool for investment-property HELOCs is smaller, the requirements are strict, and you generally can’t borrow as much as you could against a primary home.
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 reason is lien position. If a borrower stops paying, the first mortgage gets paid first from a sale. The second lien collects only what is left. That is why a second lien on a rental carries tighter caps than the same line on a residence.
One more wrinkle: the word HELOC covers two kinds of underwriting. A bank-style line reviews you: credit, debt-to-income, and equity. A rent-based product reviews the property: rent against the payment. Ask which one you are being quoted before you compare anything else.
Key Terms Defined
HELOC: a revolving line of credit secured by a property, which you draw from as needed up to a limit.
Second lien: a loan recorded behind your first mortgage, so the first lender stays in front of it for repayment.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow from the line, followed by a repayment period when you pay it down.
DSCR (debt service coverage ratio): monthly rent divided by the full monthly housing payment: principal, interest, taxes, insurance, and any HOA dues.
Cash-out refinance: a new, larger first mortgage that pays off the old one and hands you the difference.
How Does the Second Lien Leave Your First Mortgage Alone?
The line is a standalone loan recorded behind your existing mortgage. Your first loan keeps its balance, its term, and its payment schedule. The new lender simply records its own lien after the first one.
On a rental with no mortgage, the same line can take first position instead. Across the network, the line works in either slot.
Your first-mortgage documents deserve a read before you apply. Look for any language about additional liens on the property. A second lender will also see the first loan on the title report, so surprises tend to surface early.
Keeping the first loan matters most when it is a good one. A second lien lets you reach equity without trading that loan for a new one. A cash-out refinance, by contrast, replaces the old mortgage with a bigger one, so the whole balance gets repriced. Only you can judge whether your first mortgage is worth protecting.
How Does the Draw Work on Lendmire’s Network?
Lendmire is a broker, not a lender. It arranges these lines through select wholesale partners. Here is how an investment-property line is structured across the network, subject to lender guidelines and full file review:
- Ceiling: 70% CLTV on an investment property.
- Line size: $25,000 to $500,000.
- Draw structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment.
- Funding at closing: at least 75% of the line is drawn at closing.
- Pricing: it floats through both the draw and repayment periods and never converts to fixed.
That last point differs from some bank products. The CFPB notes that HELOCs usually carry a variable rate, so payments may change from month to month, and that some plans let you convert part of the balance to a fixed rate. This network’s investment line does not offer that conversion. Rent does not rise and fall in step with a floating payment, so plan for movement.
The 75% funded at closing also changes how you should think about the product. It is not a standby line you open and leave empty. Most of it is borrowed on day one.
The CFPB gives a draw period of 10 years as an example of how long some plans last. This network’s investment structure runs five.
How Big a Line Can Your Rental Support?
Your line is the CLTV ceiling times the property’s value, minus every lien already on the property. If a second lien already exists, it counts too. Here are three modeled cases at the 70% ceiling, using percentages of value only:
- Case one: your first mortgage balance is about 45% of value. That leaves roughly 25% of value as room, subject to the $500,000 cap.
- Case two: your balance is about 62% of value. Room shrinks to roughly 8% of value, which on a modest property can fall under the $25,000 minimum line.
- Case three: your balance is at or above 70% of value. There is no room, and this route is closed.
These are modeled inputs, not market data. Run your own balance and a realistic value through the same arithmetic.
Value comes from the lender’s valuation. An investment line caps at $500,000, and full appraisals begin only above that, so these lines normally run on an automated valuation with no traditional appraisal. A higher CLTV may call for a second valuation, and you may ask for a full appraisal anyway. A lower value mostly shrinks the line rather than killing the file.
NerdWallet lists at least 20% remaining equity as a market-wide expectation for investment-property HELOCs. The network’s investment ceiling is tighter: 70% CLTV means 30% of the value stays untouched.
What Does Underwriting Look at, Step by Step?
On this network, the line is underwritten on you and the property’s equity, not on the rent. Qualification runs through six checks:
1. Credit. An investment line requires a 700 minimum. Scores of 720 and 700 both reach the same 70% CLTV, so a higher score buys eligibility, not extra leverage. The score model is a single bureau, keyed to the primary wage earner, and the report can be no more than 90 days old at closing.
2. Debt-to-income. The maximum is 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw. That is stricter than it sounds, because it assumes you borrow the full line.
3. Credit history. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, foreclosure needs seven years, and a deed-in-lieu, pre-foreclosure, or short sale needs four.
4. Property. Eligible types include single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered. A property listed for sale, or listed within the past 60 days, is ineligible in some states.
5. Title. The property must be held by you individually or by your revocable living trust.
6. Exposure. A borrower is limited to three lines. Combined exposure caps range from $750,000 to $2,000,000 depending on the wholesale program. A borrower with more than 15 financed properties is not eligible.
Expect to hand over a credit authorization, proof of income or reserves, leases or rent history, insurance, and title documents. Rent is documentation here, not the qualifier. A rent-based second lien, where it exists in the market, flips that logic. For deeper background on how rent-based underwriting works, see Lendmire’s complete DSCR loans guide.
Where Do You Actually Go to Get One?
You have three channels for an equity line, and each reviews the file differently. Start with the one that already knows you.
| Channel | Best fit | How it reviews you | Tradeoff |
|---|---|---|---|
| Your current first-mortgage bank | Existing customers | Credit, DTI, equity | May decline rentals outright |
| Credit unions and regional banks | Local, portfolio-minded borrowers | Their own rules | Terms and renewal vary widely |
| Broker with wholesale network | Borrowers shopping several lenders | Varies by lender | Limited to eligible states |
Your current bank is worth a call, because a lender holding both liens sees the whole picture. Credit unions and regional banks often hold loans on their own books, so they set their own rules, and some write a renewing line of credit instead of a traditional HELOC. Ask each one whether it writes a revolving line or a fixed second, because quotes for those are not comparable.
A broker adds reach. Lendmire arranges equity lines through select wholesale partners, which lets one application meet several sets of guidelines. The catch is geography: these lines are available in 16 full-service states, a narrower footprint than Lendmire’s DSCR lending across 41 markets, including Washington, D.C. Confirm your state before you plan around it.
HELOC, Cash-Out Refinance, or DSCR Cash-Out?
The three products solve the same problem in different ways. Here is how they compare on this network, subject to lender guidelines:
| Factor | Investment HELOC | Standard cash-out refi | DSCR cash-out |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Replaced |
| Leverage | 70% CLTV (investment) | Varies by lender | Up to about 75% LTV on standard rentals |
| Reviewed on | Credit, DTI, equity | Personal income | Rental income vs payment |
| LLC title | Not allowed | Often restricted | Often fine, per program terms |
| Payment | Floating, interest-only draw | Fixed or adjustable | 30-year fixed spine |
DSCR cash-out refinances qualify primarily on property-level rental income covering the payment, subject to lender guidelines. Across the network they typically ask for about six months of seasoning and a credit score near 660, though a 620 floor exists in parts of the network. Coverage near 1.00 is where select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Short-term rental collateral steps down to 70% on cash-out, versus 75% on standard rentals.
Where the Rule Breaks: Edge Cases
LLC title. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title on this network’s equity lines. That is the sharpest structural difference from a DSCR loan. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
Moving the rental into an LLC after the line opens. Transferring title can trigger default language in the first mortgage or the line. Ask the lender for written consent before you retitle anything.
Lien position. A second-position line is harder to find than a first-position line on a free-and-clear rental. Many banks that write the latter will not write the former.
Closed-end second versus revolving line. Some lenders will not write a revolving line on a rental but will write a lump-sum second. The two behave differently, so compare like with like.
A big existing second. If another second lien already sits on the property, it eats into your room, and you may need to pay it off to proceed.
Large cash needs. An investment-property line tops out at 70% combined loan-to-value (CLTV) and $500,000. A rental that needs more than that cap points toward a cash-out refinance.
What Does a Second Lien Do to Your Coverage?
It adds a payment. If rent covers your first mortgage thinly, a second payment can erase the margin.
Keep one distinction straight: DSCR compares rent to the housing payment only. Clearing 1.00x is not the same as positive cash flow, because repairs, vacancy, management, utilities, and capex all sit outside the calculation. A line that adds to the payment cuts into both the ratio and the real-world cushion.
Picture a rental whose rent covers the first mortgage at around 1.15x. Add a second lien that is 75% drawn at closing and interest-only, and the combined payment can pull the property toward or below 1.00x. That matters later if you plan to refinance into a DSCR loan, where the new loan must pay off both liens and the coverage must work on the larger payment. A line is not free equity. It is debt that your future refinance must absorb.
Lenders in the network also review reserves, commonly around six months of PITIA (principal, interest, taxes, insurance, and association dues) on rental-related files. Reserve rules vary by lender, leverage, loan size, and transaction type.
What Are the Risks?
Four risks deserve a plain look.
- Floating payments. The line never converts to fixed on this network, and rent doesn’t flex with it.
- Payment shock. The interest-only draw ends after five years. Then the balance amortizes over 25 years, and the payment steps up.
- Stacked leverage. At the 70% ceiling, you have thinned your equity cushion. A value drop hurts more.
- Repayment source. If the rent cannot carry both liens, the funds you borrowed have to be repaid from somewhere else.
Funds are flexible. Investors commonly use them for the down payment on the next purchase, rehab, or reserves. A stronger use is one that raises the property’s income, since a renovation may support a higher appraised value, depending on comps and underwriter review. Using the line as a permanent loan on a long-term rental is the weaker fit, because the floating payment works against a fixed-rent business.
Which Route Fits You?
Think about the decision as a few plain pairings. Each one matches a common situation to the route that usually suits it.
- Keep the first mortgage and need modest cash: the second-lien line, if your title, credit, and leverage clear the checks above.
- Title is in an LLC: a DSCR cash-out, or retitle first with the lender’s consent.
- Large cash need: a cash-out refinance, since an investment line caps at $500,000.
- No bank will write a line behind your first mortgage: a DSCR cash-out removes the need for a second-lien line, at the cost of repricing your first loan.
- Thin rent coverage already: think twice before adding any payment.
Frequently Asked Questions
Can I get a HELOC on a rental that still has a mortgage?
Sometimes. Not every lender offers one and that qualification is strict. Across Lendmire’s network, a line can sit in second position behind your first mortgage, up to 70% CLTV on an investment property.
Can an LLC borrow on a rental HELOC?
No, not on this network. Title must be held by you individually or by a revocable living trust. A rental already owned by an LLC needs a vesting change, or a DSCR cash-out refinance instead.
Is a HELOC the same as a home equity loan?
They differ. A HELOC is revolving, so you borrow, repay, and borrow again within the draw period. A home equity loan, or closed-end second, is a single lump sum with a set repayment schedule. On this network’s investment line, at least 75% is drawn at closing.
What credit score do I need for an investment-property line?
At least 700 on this network. A 720 and a 700 both reach the same 70% CLTV, so a higher score adds eligibility without adding leverage. Programs vary by lender, so confirm against your own file.
Will the line require a full appraisal?
Usually not on an investment line. Because the line caps at $500,000 and full appraisals begin above that amount, these files commonly run on an automated valuation. A higher CLTV may call for a second valuation, and you can request a full appraisal in any case.
