The Quick Read: A small line draw saves money over a new first mortgage because it reprices only the new money, while a cash-out refinance reprices the entire existing balance and adds closing costs on all of it. The savings are largest when the first mortgage has favorable terms, the need is modest, and the draw is repaid within the interest-only period.
- A line leaves the existing first mortgage untouched. A new first replaces it.
- The savings come from avoided closing costs on the full balance and from not repricing the old loan.
- The advantage narrows when the draw stays outstanding for years, because the line’s pricing floats.
- On the investment lines in Lendmire’s wholesale network, at least 75% of the line is drawn at closing, so size the line to the need.
- Investment lines top out at 70% CLTV, and title must sit with an individual or a revocable trust, not an LLC.
What a Small Draw Actually Replaces
A home equity line of credit is a revolving loan secured by the property. You borrow against equity, repay, and borrow again within the draw period. A new first mortgage works differently. It pays off the old loan and writes a new one for the combined balance plus the cash you take out.
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.
That difference is the whole story. A line sits beside the existing first as a separate lien, or sometimes in first position on a free-and-clear property. The first keeps its balance, its term and its pricing. A cash-out refinance retires the old note, so the entire balance moves to whatever the market offers on the closing day.
For a landlord who needs money for a few months, that gap matters. A roof, a vacancy gap between tenants, or a deposit on the next purchase are typical short needs. Replacing a large, well-priced first to fund a modest, temporary need means paying to reprice dollars that never needed repricing.
Across Lendmire’s wholesale network, this comparison comes up often with investors who hold a first mortgage they would not want to give up. Lendmire is a mortgage broker that arranges these loans through select lenders. It does not lend directly, and every figure below is subject to lender guidelines and full file review.
Key Terms Defined
CLTV (combined loan-to-value): All liens on the property added together and divided by the property’s value.
Draw period: The stretch when you can borrow from the line and usually pay interest only.
Repayment period: The stretch after the draw ends, when principal begins to amortize.
Cash-out refinance: A new first mortgage that pays off the old one and hands you the extra equity as cash.
DSCR: Debt service coverage ratio, which compares a property’s rent to its full monthly obligation of principal, interest, taxes, insurance and any association dues.
Seasoning: The time that must pass after a purchase or refinance before a lender will lend against the new value.
Why the Line Can Cost Less Than a New First
Two things drive the savings, and neither depends on a specific number.
The first is closing cost scale. A new first mortgage carries origination charges, title work and an appraisal on the full new balance. A line is typically sized to the draw, and on a modest line the valuation can be automated. Opendoor’s HELOC explainer notes that most lines are interest-only during the draw, which keeps carrying cost low while the money is out.
The second is what stays put. Say a landlord owns a rental with a first mortgage at about half of its value. A cash-out refinance would reprice that entire half. A line adds a second layer on top and leaves the first alone. If the first carries favorable terms, keeping it is the asset being protected, and a more affordable way to borrow a small amount is usually the way that touches it least.
Here is the catch. The line floats. Its pricing moves with an index, and on the investment lines in the network it never converts to fixed. So the savings are real for a short, small need and fade as the money stays out longer.
Lendmire does not quote a dollar saving here, because it depends on the first mortgage balance, the new loan’s closing costs and the time the draw stays open. The logic still holds for any investor who knows those three inputs.
How Underwriting Treats a Rental Line, Step by Step
Step 1: Sizing by CLTV. The lender adds the first mortgage balance to the requested line and divides by value. The first balance, not its pricing, sets how much room is left. On an investment property in this network, the ceiling is 70% CLTV. A first sitting near 60% of value leaves about ten points of room. A first near 70% leaves none.
Step 2: Qualifying the borrower. A HELOC is underwritten on the borrower, not the rent. Lenders review credit, income and debt-to-income. In this network, the maximum ratio is 50%, and the check uses the interest-only payment calculated on the maximum draw. The minimum credit profile on an investment line is 700. NerdWallet’s investment-property HELOC guide says these lines come with a smaller lender pool, lower borrowing limits and stricter requirements than primary-home lines. Its market-wide survey figures run tighter on credit and reserves than primary-home lines. They describe the broader market, not this network. The network’s own investment-line figures are the 700 credit floor and 70% CLTV ceiling above.
Step 3: Valuation. Lines at or below $500,000 ordinarily run an automated valuation instead of a traditional appraisal. A borrower may request a full appraisal in any case, and a higher CLTV may call for a secondary valuation. Investment lines cap at $500,000 in total, so there is no larger investment tier.
Step 4: Title. Title must be held by the individual borrower or a revocable living trust. LLCs, corporations and partnerships cannot hold title on this product. A rental already deeded into an LLC needs a vesting change first, or a DSCR cash-out refinance instead, subject to lender program eligibility.
Step 5: The draw. On the network’s investment line, at least 75% of the line is drawn at closing. The draw period runs five years, interest only, followed by a 25-year fully amortizing repayment.
Step 6: Repayment. The CFPB’s HELOC booklet explains the general mechanics. Payments on variable lines can change even when you borrow nothing more. Interest-only draw payments put nothing toward principal. Some plans move to a repayment schedule after the draw, and others require the full balance at once.
The Structures That Exist
A short need can be met several ways. The right one depends on the first mortgage, the title, and the size of the need.
| Factor | Line behind the first | New first (cash-out) |
|---|---|---|
| Existing first | Stays in place | Paid off and replaced |
| What reprices | Only the new money | Entire balance |
| Reviewed on | Borrower credit and income | Property rent (DSCR) |
| Investment ceiling | 70% CLTV | About 75% LTV, standard rentals |
| Title | Individual or revocable trust | LLC allowed, per program terms |
| Payment type | Interest-only draw, floating | Fixed terms available |
Notice how the right side works. A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Across most of the network, cash-out tops out near 75% LTV, with about six months of seasoning as the common expectation. Credit floors start around 620 in parts of the network, most programs want about 660, and 700 or better opens the strongest leverage. Coverage of 1.00 is where many select programs start. A separate select-lender path goes below 1.00 with leverage and terms adjusted. Loan sizes generally reach up to $3,000,000 on standard programs, with smaller balances available through select lenders.
For the line, the figures are different, and they apply only to the line. Mixing the two sets of numbers is the most common way investors misjudge this choice.
Other structures sit beside these. A line can sit in first position on a free-and-clear rental. A short-term bridge loan can fit when cash is needed within a few months of purchase. And an investor who wants a larger, longer commitment may be better served by a DSCR refinance with an extended or interest-only structure, available through select lenders. For more on the small-draw scenario specifically, Lendmire’s piece How Much a Rental HELOC Saves on a Small Draw for a Short Need works through the logic from the line’s side.
Savings by How Long the Money Stays Out
Time is the variable most explanations skip. The same need produces different answers depending on how long the draw runs.
| Money outstanding | Line behind the first | New first |
|---|---|---|
| A few months | Strong advantage | Closing costs rarely recovered |
| About a year | Still favorable | Costs still weigh heavily |
| Several years | Advantage narrows | Break-even can arrive |
| Through the repayment period | Floating pricing dominates | May win if the first is also expensive |
The break-even method is simple. Add the new first’s closing costs to any prepayment penalty on the old loan. Compare that sum with the extra interest you would pay on only the new money through the line. The shorter the need, the longer the closing costs take to earn back, so the line wins. The longer the need, the more that floating interest accumulates, and the gap closes.
A line also has to be sized sensibly. Since most of the network’s investment line is drawn at closing, an investor who opens a line far larger than the need pays interest on money sitting idle. Size the line to the need, and the draw requirement stops mattering. Sized that way, the product behaves much like a closed-end second.
Where the General Rule Breaks
The savings argument is strongest on paper. In practice, several edge cases can flip it.
The line may not exist. Investment-property lines are harder to find than primary-home lines. Lenders see more default risk on rentals, and the lender pool is smaller. The network has its own boundary too. Its HELOC product is available only in Lendmire’s 16 full-service states, which is narrower than the 41-market DSCR footprint.
Title is an LLC. Many landlords hold rentals in an entity. If title sits in an LLC, the line is off the table until title moves, and moving title has its own costs and lender considerations. That alone can push the investor toward a DSCR cash-out.
Thin equity. With a first near the 70% ceiling, no room is left for a line, and a cash-out may be the only path. Even at modest room, the $25,000 minimum line size can exceed what a thin margin allows.
The first has a prepayment penalty. A penalty stays in force if you add a second lien. It also becomes a direct cost if you refinance, because a cash-out is a refinance. Check the note before comparing anything.
Property type. Manufactured homes, co-ops, condotels, log homes and mixed-use properties are not eligible for the network’s line. Single-family, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condos, are eligible.
Credit history. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure history on an investment file follows a seven-year path, and a deed-in-lieu, pre-foreclosure or short sale follows four.
Due-on-sale and additional-lien clauses. Some first-lien documents restrict junior liens. Whether federal protections for junior liens reach a business-purpose rental is not settled enough to rely on here. Reading the first mortgage documents before applying is the right move, and a lawyer can interpret them.
Portfolio size. A borrower owning more than 15 financed properties is not eligible for the line, and a borrower is limited to three lines.
What the Decision Looks Like in Practice
Picture a landlord with one rental held personally, a first mortgage at roughly half of value, and a short-term need that will be repaid when a tenant turnover finishes. The line fits. It leaves the first alone, the CLTV room is ample, and repayment comes well inside the five-year draw.
Now picture the same landlord with the property inside an LLC. The line is not available until title moves. A DSCR cash-out refinance reaches around 75% LTV on a standard rental, with roughly six months of seasoning. That path reprices the whole balance, so the choice depends on how the existing first compares with current terms. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
A third investor is self-employed with low taxable income. HELOC underwriting leans on personal debt-to-income, so a line may be harder to get than the rent would suggest. A DSCR file reads the property’s rent against the full payment instead. That is where the two tools diverge: one asks about the borrower, the other about the building.
Keep one point in mind on the DSCR side. The coverage ratio compares rent to the full monthly obligation only. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, management, utilities and capital expenses sit outside the calculation. A line payment also comes out of the same rent, so adding it lowers the cushion even though it sits outside the first’s ratio. Lendmire’s how much a lock-in landlord saves with a rental HELOC over a new first covers that interaction from the owner’s side.
The decision usually reduces to five questions:
1. Does the first mortgage have terms worth keeping?
2. Is the title in your name or a revocable trust?
3. Is there CLTV room under the ceiling that applies to this occupancy?
4. Will the draw be repaid well before the draw period ends?
5. Does the line carry annual, inactivity or early-closure fees that cut into the savings?
If all five answers favor the line, it typically costs less than a new first. If two or more do not, replacing the first or choosing a DSCR cash-out deserves a closer look. The full structure behind that second path is laid out in the complete DSCR loans guide.
Costs Beyond the Pricing
Fees decide many of these comparisons, and the CFPB’s booklet is clear about them. Some lenders waive some or all up-front costs, and others charge appraisal, application, closing and early-termination fees. It also advises asking about annual fees even when the line is unused. So no closing cost does not always mean no cost. Charges can reappear as annual, inactivity or closure fees.
For a short need, the question is whether to carry an empty line or close it. If closing triggers a fee, compare that fee with the cost of keeping the line open. This is an agreement-level item, so the exact answer sits in the loan documents.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Risks Worth Sizing
- Floating pricing. A short need that runs long carries payment risk. Payments can change even if you draw nothing more.
- Payment step-up. When the draw period ends, principal begins. Opendoor describes this step-up, which is why repaying before the draw ends matters.
- Collateral. The property secures the line. Missed payments put it at risk.
- Qualification path. An investor who clears the line’s borrower test can still be turned away for title, property type or equity reasons.
Every file is underwritten individually, and programs change. These are typical ranges, not promises.
Frequently Asked Questions
Can a HELOC draw be small if most of the line is drawn at closing?
Yes, if the line itself is sized small. On the network’s investment line, at least 75% of the line is drawn at closing, so the draw tracks the line size. A line near the minimum size keeps the opening draw modest. Opening a large line and hoping to draw little does not work on this product.
Does a HELOC change my existing first mortgage?
No. The line is a separate loan that sits in second position, or in first position on a free-and-clear property. The existing first keeps its balance, term and pricing. A cash-out refinance, by contrast, retires the old first and replaces it.
Can I get a HELOC on a rental held in an LLC?
Not on this network’s product. Title must be held by the individual or a revocable living trust. An LLC-held property needs a vesting change or a DSCR cash-out refinance instead, depending on program guidelines.
What is the maximum leverage on an investment-property line?
On an investment property the ceiling is 70% CLTV, with a 700 minimum credit profile and a $500,000 maximum line. Primary residences and second homes can reach higher, with 90% available only at a 720-or-better profile. Market surveys report other figures, but they describe the broader market, not this network.
When does a new first beat a small draw?
When the need is large, when it will stay outstanding for years, when the first mortgage is already expensive, or when title or equity rules block the line. A DSCR cash-out refinance on a standard rental tops out near 75% LTV and is reviewed on rental income covering the payment, subject to lender guidelines.
