The Quick Read: A home equity line lets an investor borrow against property equity while the existing low-rate first mortgage stays exactly as it is. Which lenders fit depends on how the property is titled, how much combined leverage remains, and the borrower’s credit profile. Lendmire is a mortgage broker, not a lender. It matches each file to a wholesale HELOC lender whose program fits.
- On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit profile.
- The property must be titled in an individual’s name or a revocable living trust. LLC-held rentals are generally out.
- Pricing floats and never converts to fixed. Keeping your first mortgage does not mean the new money carries a fixed cost.
- If the property sits in an LLC, a DSCR cash-out refinance is usually the better route.
Why Investors Choose a Second Lien Over a Refinance
A cash-out refinance replaces the entire first mortgage, so the new terms apply to the whole balance. A home equity line sits behind the first loan and prices only the new money. If your existing first mortgage is well below what a new loan would cost, a second lien protects that advantage.
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 trade runs both ways. A second lien adds a payment on top of the first, and the new money usually costs more than the old first mortgage. The right choice depends on how large the draw is compared with the first-mortgage balance. A small draw against a large, cheap first mortgage favors the line. A large draw can reverse that math.
Investors tend to use this strategy for three jobs: a down payment on the next rental, a rehab budget, or building reserves. All three are one-time or staged needs, so the sizing question comes before the lender question.
How a HELOC Works Behind Your First Mortgage
A home equity line is an open-end line of credit. You borrow against equity up to a set limit, repay, and borrow again during the draw period. The Consumer Financial Protection Bureau explains that many lines require only minimum payments based on the current balance during that period.
Here is how the process runs on a brokered file:
1. Lien position. The line is recorded as a junior lien. Your first mortgage keeps its note terms, servicer, and payment.
2. Combined leverage. Lenders add the first-mortgage balance to the requested line and divide by the property’s value. That figure is the CLTV.
3. Qualification. A home equity line qualifies the borrower on personal income, debt-to-income ratio (DTI), and credit. The network’s maximum DTI is 50%.
4. Valuation. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. Any line above $500,000 requires a full appraisal, and a borrower may ask for one on a smaller line.
5. Draw. The program network requires at least 75% of the line to be drawn at closing.
6. Repayment. Interest-only draw payments are followed by fully amortizing repayment.
Step 5 surprises people. On this network, a line is not an idle reserve you open and leave untouched. Most of it is drawn immediately, so you start paying on that balance right away.
What Wholesale HELOC Lenders Look For on a Rental
Every figure here is a typical range from select wholesale lenders, subject to lender guidelines and full file review.
Occupancy changes the ceiling. This is the point most borrowers miss, so the three tiers are listed separately, each with its own minimum credit score:
- Investment property: a 70% CLTV ceiling, 700 minimum credit, lines up to $500,000.
- Second home: up to 90% CLTV, but only at a 720 or better credit profile. The minimum credit score for a second home is 640.
- Primary residence: also up to 90% CLTV, again only at 720 or better. Lines run up to $750,000, and a line above $500,000 is primary-residence only.
Structure on a rental. Investment lines use a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Primary residences and second homes also have a shorter option, a 3-year draw followed by a 17-year repayment. Pricing floats through both the draw and repayment periods and never converts to fixed. Lines run from $25,000 up.
Eligible property types. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agricultural zoning are not eligible.
Credit history. The credit report cannot be older than 90 days at closing. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, a foreclosure follows a seven-year seasoning path. A deed-in-lieu, pre-foreclosure, or short sale follows a four-year path.
Exposure. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible.
Where it’s available. This product is brokered in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the 41-market DSCR footprint.
How Much Can You Actually Borrow?
The line is whatever room remains under the CLTV ceiling. Run it in percentages of value.
Say a rental’s first mortgage equals 55% of its value. At the 70% investment ceiling, the room for a new line is 15% of value. A first mortgage at 65% of value leaves only 5%. That is likely too little to justify the line’s costs and the added payment.
A borrower who has paid the first mortgage down, or whose property has appreciated, has more room. A borrower who bought at high leverage and has not yet built equity may find the ceiling leaves almost nothing.
The valuation matters too. If you recently completed improvements, an automated valuation may not capture them. A full appraisal may support a higher appraised value, depending on comps and underwriter review. An investor discussion on BiggerPockets makes the same point: after a rehab, automated valuations are a poor fit. It also notes that rental HELOCs come from a limited set of lenders.
Market-wide, equity lines on rentals often run lower than owner-occupied lines. On this network the investment ceiling is 70% CLTV, with no higher tier.
Which Lender Fits Which Investor?
Lenders that fit depend on the file. Large retail lenders and depository institutions tend to underwrite personal income and DTI. Many limit rental lending or exclude entity-owned properties. A mortgage broker shops multiple wholesale lenders and matches property type, credit, leverage need, and title to a program.
The more useful comparison is between structures:
| Factor | HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| Existing first mortgage | Stays in place | Paid off and replaced |
| Reviewed on | Personal income, DTI, credit | Property rent coverage |
| Title | Individual or revocable trust | LLC possible |
| Investment ceiling | 70% CLTV | About 75% LTV (standard rental) |
| Payment structure | Interest-only draw, then amortizing | 30-year fixed spine |
On the DSCR side, coverage compares rent with the full housing payment: principal, interest, taxes, insurance, and any HOA dues. A 1.00 ratio is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Cash-out refinances on standard rentals typically top out around 75% LTV and expect about six months of seasoning. For short-term-rental collateral, the cash-out ceiling is 70%.
Clearing 1.00 does not mean the property cash flows. Repairs, vacancy, management, utilities, and capital expenses sit outside the ratio.
The complete DSCR loans guide covers the cash-out path in depth.
Where the General Rule Breaks
LLC title. A home equity line must be held by an individual or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. BiggerPockets members report that some lenders will do investment-property lines only in a personal name, while others tolerate entities. On this network the rule is firm. If your rental is already in an LLC, you need a vesting change or a DSCR cash-out refinance, subject to lender program eligibility.
Fixed-rate expectations. Many borrowers want a locked rate on part of the balance. The investment line here does not offer one. Pricing floats for the life of the line. If a fixed payment matters, a cash-out refinance or a closed-end structure is the better conversation, though a refinance would replace your first mortgage.
Restrictions on subordinate financing. If the first mortgage is itself a DSCR loan, its note and deed of trust may restrict subordinate financing. Check them before you apply.
Using a primary-residence line to buy rentals. A line on your own home can fund a down payment. A BiggerPockets thread says this works if you have enough equity. It also says purchase lenders scrutinize borrowed down-payment funds. A DSCR purchase typically runs 75%-80% LTV, with select high-leverage programs reaching 85% at roughly a 700+ score. Know how the lender will treat the source of the cash.
Subordination. A second lien that stays in place can block a later refinance of the first unless the second lender agrees to subordinate. Plan for that before you refinance.
Credit and property. An investment line on this network requires a credit score of at least 700, so a lower score rules it out.
Too many properties. A borrower who owns more than 15 financed properties is not eligible for a line on this network. At that scale, rent-based financing is usually the practical path.
The Risk Side: Draw Period to Repayment
Floating pricing on top of a fixed first mortgage creates a blended cost that can rise. Plan for that on the line.
The bigger shock is the repayment transition. After a 5-year interest-only draw, the balance starts to amortize over 25 years, and the payment steps up. Run your coverage and DTI against that future payment, not only the draw-period payment. Qualification itself uses the interest-only payment calculated on the maximum draw.
The CFPB’s HELOC booklet notes that lenders can generally freeze or reduce a line if the home’s value falls or the borrower’s financial situation worsens. Do not count on an unused line as guaranteed liquidity. The booklet also says that if you sell, you are generally required to pay off the line in full right away.
The CFPB also cautions that you should only take a line if you can keep up with the payments, because falling behind could cost you the property. On a rental, the property secures the line.
Key Terms Defined
Second lien: a loan recorded behind your first mortgage, paid after the first if the property is sold or foreclosed.
Combined loan-to-value (CLTV): the first-mortgage balance plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow from the line and pay interest only.
Repayment period: the stretch after the draw when the balance amortizes.
DSCR: monthly rent divided by the property’s full housing payment, used by DSCR loans to size coverage.
A Checklist Before You Apply
Ask any lender or broker these questions:
- Does this program allow the property’s current title? If it sits in an LLC, what is the plan?
- What is the CLTV ceiling for this occupancy and credit tier?
- Is the line first or second lien, and does my first mortgage restrict it?
- How much must I draw at closing?
- Will the valuation be automated, or do I need a full appraisal?
- What happens to my payment at the transition to repayment?
- Which fees apply, and what are the draw minimums after closing?
The minimum subsequent draw on the longer-draw structure is $1,000.
Who This Fits, and Who Should Skip It
A personally titled rental owner with a strong first mortgage, ample equity, and a 700+ score fits well. So does a borrower who needs a defined amount and accepts floating pricing.
An LLC-held portfolio should skip it. So should a highly leveraged borrower, someone whose credit sits under 700, and anyone who needs a fixed payment.
Frequently Asked Questions
Can I get a HELOC on a rental property without refinancing my first mortgage?
Yes, if the property is titled in your own name or a revocable living trust and you meet the credit and CLTV tests. On an investment property the network ceiling is 70% CLTV with a 700 minimum credit profile. Your first mortgage stays in place.
Does a HELOC on an investment property have a fixed rate?
No. The line’s pricing floats during both draw and repayment and never converts to fixed. Compare that with a refinance if payment certainty matters more than keeping your first loan.
Can my LLC take out a HELOC?
Not on this network. LLCs and corporations cannot hold title on these lines. A DSCR cash-out refinance is the usual alternative, subject to lender program eligibility.
How much equity do I need?
You need room under the ceiling after your first mortgage. At 70% CLTV on an investment property, a first mortgage at 55% of value leaves 15% of value to borrow. Credit, valuation, and DTI still apply.
Is a HELOC or a cash-out refinance better for keeping my low rate?
The line preserves your first mortgage, so the savings are largest when the draw is small compared with the first balance. A cash-out refinance can make more sense for a large draw, an LLC-held property, or a borrower who wants a fixed payment.
