The Quick Read: The best program for your situation depends on whether you need the cash once or in stages, because a true revolving line suits stages while a lump sum fits a line drawn mostly at closing, a closed-end second lien, or a cash-out refinance. On an investment property in Lendmire’s wholesale network, an equity line tops out at 70% CLTV (combined loan-to-value, meaning the first mortgage plus the new line against the home’s value) and $500,000. At least 75% of that line is drawn at closing, so it behaves partly like a lump sum.
- Investment lines need a 700 credit score at minimum. A 720 score buys no extra leverage, because both tiers reach 70% CLTV.
- Pricing on the line floats through the draw and the repayment period and never converts to fixed.
- LLCs cannot hold title on these lines. Owners with the rental in an LLC usually look at a DSCR cash-out instead.
- Keeping a good first mortgage points toward a second lien or line. Replacing it points toward a cash-out.
What Is an Investment Property HELOC, and Why Is a Lump Sum Awkward?
A HELOC is a home equity line of credit. You borrow against the equity in a property, and the line sits in first or second position on the title. On a rental, the collateral is the rental itself.
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 textbook version is a revolving line. You draw, repay, and draw again during a set window. That shape fits a phased rehab or costs you can’t price yet. It fits poorly when you need one defined sum for a buyout, a down payment, or a payoff.
So “lump sum” and “HELOC” pull in different directions. In practice, three structures can deliver one large sum from a rental’s equity:
1. A line drawn mostly at closing.
2. A closed-end second lien, often called a home equity loan.
3. A cash-out refinance that replaces your first mortgage.
NerdWallet notes that home equity loans on investment properties aren’t widely available and can cost more than loans on primary homes. That matches what brokers see. Many big banks simply decline non-owner-occupied collateral, which is why a broker who shops several wholesale lenders matters here.
Which Structure Fits a Lump Sum? A Side-by-Side Look
Here is how the structures compare. The line column reflects Lendmire’s wholesale network on an investment property. The other columns are general product traits.
| Factor | Equity line | Closed-end second | Cash-out refinance |
|---|---|---|---|
| How funds arrive | 75%+ drawn at closing | One lump sum | One lump sum |
| Payment pattern | Interest-only, then amortizing | Fixed schedule, usually | New payment on whole balance |
| Your first mortgage | Stays in place | Stays in place | Replaced |
| Number of payments | Two | Two | One |
| Qualifies mainly on | Personal credit, income, DTI | Varies by lender | Rent (DSCR) or personal income |
The row that matters most is the first mortgage. A line or second lien leaves it alone, so you keep its existing terms and add a payment. A cash-out replaces it, so the new terms apply to the entire balance.
How Does Underwriting Treat an Investment Line, Step by Step?
Underwriting is the lender’s file review. On an investment line, the review follows a predictable order.
Step 1: Eligibility of the property. Single-family homes, 2-4 unit buildings, PUDs, townhomes, and condominiums (including non-warrantable condos) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Step 2: Title and vesting. The property must be held by you as an individual or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. This is the sharpest difference from a DSCR loan. A property already deeded to an LLC needs a vesting change or a different product.
Step 3: Credit. The floor on an investment line is 700, with no tier beneath it. The lender uses a single-bureau score model keyed to the primary wage earner, and the report can be no more than 90 days old at closing. Experian makes the same general point: a rental line typically asks for a stronger credit profile, lower debt-to-income, and bigger reserves than a primary-home line.
Step 4: Income and DTI. This is personal-income underwriting. DTI (debt-to-income, your monthly debts against your monthly income) maxes out at 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw. That detail catches people. You are tested as if the line were fully drawn.
Step 5: Leverage. The ceiling is 70% CLTV on an investment property, whatever your score. Stack your first mortgage and the new line, and the total can’t pass 70% of value.
Step 6: Valuation. Because an investment line caps at $500,000, and full appraisals begin only above that, the file ordinarily runs on an automated valuation rather than a traditional appraisal. A higher CLTV may trigger a secondary valuation, and you can request a full appraisal in any case.
Step 7: Exposure and history. A borrower is limited to three lines. Anyone owning more than 15 financed properties is not eligible. 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.
Every figure here is subject to lender guidelines and a full file review. None of it is a commitment to lend.
How Does the Draw Structure Work, and Where Does the Payment Jump?
Investment lines run one structure: a 5-year interest-only draw, then a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. After closing, you can take further draws, and the minimum subsequent draw is typically $1,000 (higher in some states).
The CFPB’s HELOC booklet describes the same basic anatomy: a draw period, then repayment. It also warns that variable pricing can change your payment even when you borrow nothing new. In this network, pricing floats across both phases and never converts to fixed.
During the interest-only years, the payment covers only the cost of borrowing. When repayment starts, principal joins the payment, and the monthly obligation steps up. That step-up is the main risk with a line. A sensible stress test uses the end-of-draw payment, not the early one.
The 75%-at-closing rule creates a practical sizing point. If you need one defined sum, size the line so your need is at least 75% of it. A need of 90% of the line passes. A need of 40% means the lender wouldn’t write the line that large.
A Worked Example
Say you own a duplex with a first mortgage equal to about 50% of its value. Your credit is above 700. You need a sum equal to about 18% of the property’s value for a buyout.
- The 70% CLTV ceiling leaves room of about 20% of value above the first mortgage.
- A line sized at that 20% room, drawn at about 90%, satisfies the 75%-drawn rule and covers your need.
- You keep the original first mortgage untouched and add one second payment.
Now change the facts. Your first mortgage already sits at 60% of value, and you need 18%. The 70% ceiling leaves only 10% of value in room, so the line can’t cover the need. A cash-out refinance is the more likely path, since it can restructure the whole balance.
Illustrative only. Your result depends on the property, credit, and lender review. The calculator on this page gives an illustrative estimate, not a quote.
When Does a Cash-Out Refinance Beat a Line?
A cash-out beats a line in three common cases:
- Your first mortgage is expensive or a poor fit. Replacing it costs little in lost advantage.
- Your rental is in an LLC. The line can’t hold title in an LLC, while a DSCR cash-out generally lets the entity stay on title, subject to program eligibility.
- You want one payment and one loan.
Across Lendmire’s network, a DSCR cash-out on a standard rental tops out around 75% LTV. For short-term-rental collateral, the cash-out ceiling is 70%. About six months of seasoning, meaning ownership time before you can pull cash out, is the common expectation. Credit floors run from about 620 in parts of the network to roughly 660 on most programs. A 700+ score opens the strongest leverage tiers.
This path qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That matters if heavy DTI or a self-employed income shuts you out of a personal-income line. A coverage ratio at or above 1.00 is where many select programs start. A separate select-lender path goes below 1.00 with leverage and terms adjusted. Clearing 1.00 does not mean the property cash-flows. Repairs, vacancy, management, and utilities sit outside the calculation.
The complete DSCR loans guide covers the full mechanics. DSCR files span 41 markets, including Washington, D.C. Lendmire’s equity-line programs, though, run only in its 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.
Where the Rules Break: Edge Cases
An existing DSCR first mortgage. A second lien is only possible if the first lender’s documents permit it. Check that before you apply. If you plan to buy with a DSCR loan and borrow against another property for the down payment, ask the DSCR lender about borrowed-funds rules first.
A property listed for sale. In NC, PA, TN, TX, and WA, a property listed for sale, or listed within the past 60 days, is ineligible. Also keep in mind that New Mexico and Ohio apply a CLTV cap that depends on the credit profile.
Large lines. A line above $500,000 is primary-residence only. On an investment property, $500,000 is a hard stop.
Texas. Texas properties are limited to 10 acres. The homestead rules that bind a Texas primary residence don’t apply to investment properties, which are treated as non-homestead transactions.
Product naming. Some lenders won’t write anything labeled HELOC on a rental. A closed-end second or rent-based second may exist under another name. That is why a broker who sees many lenders’ guidelines can find options that a single bank’s website won’t show.
What Cautions Apply to Any Financing on a Rental?
Two cautions apply to any financing that sits alongside or behind your existing mortgage:
- Stacked leverage. A second lien raises your total leverage. If values soften, your cushion thins faster than it would on a single mortgage.
- Variable pricing. A floating payment can rise at the reset. Test the end-of-draw payment before you commit.
Who Should Skip This Line?
Skip the line, or look at a different product, if any of these describes you:
- Your score is below 700. The investment floor has no tier beneath it.
- Your DTI sits above 50%.
- The rental is titled in an LLC, corporation, or partnership.
- The property is a manufactured home, log home, barndominium, or mixed-use building.
- You need less than 75% of the smallest line the lender would write.
- You want a fixed payment you can plan around for decades.
Which Structure Matches Your Use of Funds?
- Buyout of a partner or co-owner: a single defined sum, so a line drawn mostly at closing, a closed-end second, or a cash-out.
- Down payment on another purchase: a line or second on the rental you own, with the new lender’s borrowed-funds rules checked first.
- Payoff of a maturing balloon or expensive loan: a cash-out often fits, since it replaces the obligation.
- Phased renovation: a line suits staged draws better than any lump-sum product, though the 75%-at-closing rule limits how staged it can be.
- Reserves: a line you draw mostly at closing doesn’t build reserves slowly. Plan the sum, not the cushion.
What Does the Process Look Like?
A broker begins by matching your scenario to the right program. Gather your credit authorization, the current first-mortgage statement, proof of ownership and vesting, income documents, and insurance details. The lender orders the valuation. Underwriting reviews the file. Then you close. Lendmire is a broker, not the lender, so the lender makes the approval decision.
Key Terms Defined
CLTV: Combined loan-to-value. Your first mortgage plus the new line, divided by the property’s value.
Draw period: The window when you can borrow from the line. On an investment line here, it is 5 years, interest-only.
Repayment period: The phase after the draw, when principal and interest are both due. Here it runs 25 years.
Closed-end second lien: A single lump-sum loan behind your first mortgage, with a set repayment schedule.
Cash-out refinance: A new, larger first mortgage that pays off the old one and hands you the difference.
Vesting: How the property’s title is held, such as an individual, a revocable trust, or an LLC.
DSCR: Debt service coverage ratio. Monthly rent divided by the full monthly obligation of principal, interest, taxes, insurance, and any association dues.
Frequently Asked Questions
Can a HELOC on a rental really give me a lump sum?
Partly. A line on an investment property in Lendmire’s network requires at least 75% drawn at closing, so most of the money arrives at once. Pricing still floats and payments still step up after the draw. For a fully fixed sum, a closed-end second or a cash-out is the cleaner shape.
What is the maximum I can borrow against a rental?
The ceiling is 70% CLTV on an investment property, with a maximum line of $500,000. Market-wide, some products advertise higher leverage on primary homes, but NerdWallet cautions that rental equity products are less available and can cost more.
Can I use an LLC-owned rental?
Not for the equity line. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A revocable living trust works. A DSCR cash-out generally lets an entity stay on title, subject to program eligibility.
Will I need an appraisal?
Usually not a traditional one. Lines at or below $500,000 ordinarily run an automated valuation, and an investment line can’t exceed that size. A higher CLTV may require a secondary valuation, and you can always request a full appraisal.
What happens when the draw period ends?
Repayment begins and principal is added to the payment, so the monthly obligation rises. Pricing floats the whole way and never converts to fixed. Run the numbers at the repayment-phase payment before you borrow.
