The Quick Read: A new lender sizes a replacement HELOC by multiplying the property’s value by its maximum combined loan-to-value, subtracting every lien that will remain after closing (a retired old line is paid off and released, so it is not counted among them), and then capping the result by dollar limits, credit, and debt-to-income tests. The smallest of those limits wins. On a rental, the numbers are tighter than most investors expect.
- The old line is not a lien that stays. Its payoff comes out of the new line’s first draw.
- On Lendmire’s network, an investment-property line tops out at 70% CLTV (combined loan-to-value) with a 700 minimum credit score.
- Paying a HELOC to zero does not remove the lien. The line must be closed and released.
- An LLC cannot hold title on a HELOC. A rental deeded to an LLC points toward a DSCR cash-out instead.
- Only the new lender’s own valuation counts. The old lender’s number does not carry over.
Replacing a HELOC is not a rollover. It is a fresh application, a fresh value, and a fresh lien stack. Appreciation helps you. A value drop hurts you. This guide walks through the sizing math, the limits that cap it, and the point where a rental investor is better off with a DSCR cash-out. Lendmire is a mortgage broker. It arranges these loans through select wholesale partners and never lends directly.
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.
Key Terms Defined
HELOC. A home equity line of credit is a revolving line secured by a property. You borrow during a draw period, then repay.
CLTV. Combined loan-to-value adds every loan against the property and divides by its value. The first mortgage and the HELOC both count.
Lien. A lien is a recorded legal claim on the property. It stays on title until it is released.
Payoff amount. This is the figure that clears a loan on the closing date. It includes interest to that date and any fees, so it is rarely the same as the statement balance.
Lien release. The old lender files this paperwork to remove its claim from the public record.
AVM. An automated valuation model estimates value with data instead of a visit from an appraiser.
DSCR. Debt service coverage ratio compares a property’s rent to its full monthly obligation. It is the test on DSCR loans instead of personal income.
PITIA. Principal, interest, taxes, insurance, and association dues make up the monthly obligation in the DSCR test.
How Does a New Lender Size the Line?
A new lender runs five steps in order: value, ceiling, remaining liens, borrower tests, and program caps. Each step produces a number. The final line is the smallest of them. Most investors only look at step two, which is why the answer surprises them.
1. Establish value. The lender orders an AVM or an appraisal. On Lendmire’s network, lines at or below $500,000 ordinarily run an AVM with no traditional appraisal. A higher CLTV may require a second valuation. You can also request a full appraisal. Every line above $500,000 needs one.
2. Apply the CLTV ceiling. Multiply value by the maximum CLTV for your occupancy and credit tier. On an investment property that ceiling is 70% CLTV.
3. Subtract the liens that remain. Include the first mortgage and any other second lien. Include the old HELOC only if it will stay open. If it is being paid off and closed, it drops out.
4. Run the borrower tests. A HELOC is underwritten on you: credit, income, and debts. The network’s maximum DTI is 50%, qualified on the interest-only payment calculated on the maximum draw. It drops to 45% for credit profiles from 600 to 679.
5. Apply the dollar cap. The maximum line is $500,000 on an investment property and a second home. It reaches $750,000 only on a primary residence.
Notice what the borrower tests assume. The lender does not test the payment on what you plan to borrow. It tests the maximum draw.
Worked Example: Old Line Paid Off vs. Left Open
The old line’s treatment changes the answer more than any other input. The table below uses percentages of value so the logic stays visible. These are modeled assumptions for an investment property, not market data or a quote.
| Input (% of value) | Old line paid off and closed | Old line left open |
|---|---|---|
| Maximum CLTV | 70% | 70% |
| First mortgage remaining | 40% | 40% |
| Old HELOC counted as a lien | 0% | 20% (full limit) |
| Maximum new line | 30% | 10% |
| Old payoff (modeled at 15%) | Paid from first draw | Not applicable |
| Left for other uses | 15% | 10% |
In the left-open column, the lender counts the whole old limit, not just the drawn balance. A recorded HELOC lien covers the full limit, as LegalClarity explains. So an unused line still eats room. Ask any new lender directly whether the undrawn portion counts.
There is one more twist on Lendmire’s network. At least 75% of the line must be drawn at closing. That fits a replacement well. The old payoff and closing costs come out of that first draw. But it means you cannot open a large line and leave it idle.
Now the benchmark. NerdWallet reports that investment-property HELOCs commonly want 720 or higher credit and allow up to 80% LTV, with many lenders sitting below 70%. That describes the broader market. On Lendmire’s network, an investment line tops out at 70% CLTV with a 700 floor. Nothing above that is available on a rental.
Which Limit Actually Binds?
Whichever number is smallest sets the line. Investors often fix on equity and miss the dollar cap or the debt test.
| Limit | How it works | Network figure |
|---|---|---|
| Equity room | Value × CLTV ceiling − remaining liens | 70% CLTV on investment |
| Dollar cap | Fixed maximum line by occupancy | $500,000 investment; $750,000 primary |
| Borrower capacity | DTI on interest-only payment at max draw | 50% max; 45% at 600-679 |
Run it in your head. A rental with plenty of equity can still be held down by DTI. A lightly leveraged $1.2 million rental runs into the $500,000 cap first. Equity is only one gate.
Primary residences and second homes have a wider ceiling. Primary lines run up to 90% CLTV, but only at a 720-or-better credit profile and up to $500,000. A second home also reaches 90% at 720 and above, with a $500,000 cap. At 700 on a primary, the ceiling is 85% up to $500,000. Investment lines never get these tiers.
Why a New Lender’s Number Can Differ From the Old One
A new lender builds its own file. It picks its own valuation method, its own value, and its own ceiling. Do not assume the first lender’s appraisal carries over.
Valuation is the first swing factor. An AVM and a full appraisal can land in different places on the same property. A lower value shrinks the line at the same ceiling.
The second factor is the freeze. A HELOC is a revolving line, and the lender can sometimes cut or suspend it. The Philadelphia Fed’s Consumer Compliance Outlook lists a significant decline in property value and a borrower’s default on a material obligation as grounds. It also lists the lender’s reasonable belief that the borrower cannot repay. That is why a replacement line may come in smaller than the one you lost.
If your old line was frozen, Lendmire’s piece Can You Replace a Frozen HELOC With a New Line From Another Lender? covers that case in detail.
Here is a practitioner point from watching many equity files. The investor who held a line for years remembers its limit. The new lender sees today’s value and today’s liens. The mismatch is where most disappointment comes from.
Full Limit vs. Drawn Amount
Lenders size and test the maximum, not your intention. Two places this shows up:
- Lien counting. An old line left open counts at its full limit in CLTV, as the table showed.
- Payment testing. The new line is qualified on the interest-only payment at the maximum draw.
The CFPB notes that a HELOC has a draw period followed by a repayment period, and that payments can change from month to month. On Lendmire’s network, investment lines use one structure only: a 5-year interest-only draw followed by 25 years of full amortization. Primary residences and second homes also have a 3-year draw with a 17-year repayment. Pricing floats through both phases and never converts to fixed. A short draw means the payment steps up sharply later.
Working backward helps. Start from the payoff on the old line. Add closing costs. That total is the minimum draw the new line must support. If the maximum new line cannot cover it, the replacement does not work as planned.
What Happens at Closing
At closing, the new lender pays the old one. Then the old line has to be closed and released.
1. Get a payoff statement. The payoff includes interest through the closing date and fees. Do not use the statement balance.
2. Title agent pays the old lender from the new line’s first draw.
3. Close the old account in writing. Do not skip this step. A zero balance is not enough.
4. Confirm the release is recorded. The lien stays on title until the lender files a release. Counties typically charge a recording fee.
This is a common mistake. Paying a line to zero leaves the full limit recorded against the property while the account is open. A later lender will see it and count it. Skip the closure and you carry a hidden lien.
Where the Network’s HELOC Rules Break
A few edge cases break the general rule on a rental. Each one decides whether a HELOC is even available.
LLC title. The borrower must hold title personally or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out instead. DSCR loans to LLC-titled borrowers are subject to lender program eligibility.
Property type. Single-family, 2-4 unit, PUD, townhome, and condominium properties, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not.
Exposure limits. A borrower is limited to three lines in total. Combined exposure caps vary by program. A borrower with more than 15 financed properties is not eligible. Portfolio investors hit this one first.
Listed property. In several states, a property listed for sale within the past 60 days is ineligible.
Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files with a foreclosure follow a 7-year path, or 4 years after a deed-in-lieu, pre-foreclosure, or short sale.
Availability. Lendmire arranges these equity lines in 16 full-service states only. That is narrower than its 41-market DSCR footprint, which covers 40 states plus Washington, D.C.
Insufficient proceeds. If the new line cannot cover the old payoff, you either bring cash or leave the old line open. Then it counts as a lien. The math in the table above gets worse.
Replace, Roll In, or Pay Off?
You have three routes. The right one depends on the property and how you want to hold the debt.
| Route | What it replaces | What you keep | Best fit |
|---|---|---|---|
| New HELOC | Old HELOC only | Existing first mortgage | Personal-name rental, ample equity |
| DSCR cash-out | First mortgage and HELOC | Nothing; one new loan | LLC title, many properties, rent-driven file |
| Pay it off | Old HELOC from cash | First mortgage | Cash on hand, no new debt |
The trade-off with a cash-out is the first mortgage. Rolling in a HELOC also retires your existing first loan. If that first loan has terms you like, you lose them. It also puts the full amortizing payment, not an interest-only line payment, into the coverage test.
For a pure rental, this is where DSCR often wins. A DSCR cash-out qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC leans on your credit and personal DTI. Here is what the cash-out side typically looks like across Lendmire’s wholesale network:
- Leverage. Cash-out tops out around 75% LTV on standard rentals and 70% on short-term-rental collateral.
- Seasoning. About 6 months of ownership is the common expectation.
- Coverage. 1.00 is where select programs start, not a universal standard. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
- Credit. A 620 floor exists in parts of the network. Most programs want around 660, and 700 and above unlocks the strongest tiers.
- Loan size. up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000 the network generally holds to 30-year fixed structures.
- Reserves. They vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common.
Clearing 1.00 is not the same as positive cash flow. DSCR counts only rent against PITIA. Repairs, vacancy, management, and utilities sit outside it.
A small amount of cash at closing may still leave a DSCR refinance classed as rate-and-term when it pays off a HELOC. The threshold varies by program, so confirm it before you plan around it. Prepayment terms on a new DSCR loan also vary. Read them before you refinance out of a loan you recently placed.
For the broader mechanics, see the complete DSCR loans guide. For the closest parallel on the first-lien side, Lendmire’s piece Cash-Out Refinance for Homeowners Whose New Loan Replaces the Old One is worth a read.
Before You Apply
Gather these before any lender sizes the file:
- A payoff statement for the old line, with the closing-date interest and fees.
- The current first-mortgage balance and any other liens.
- Proof of how title is held: personal name, trust, or LLC.
- A realistic value estimate, and an understanding that the lender’s number rules.
- Your count of financed properties and your current lines.
- A credit report picture. Reports are good for no more than 90 days at closing, with no rescores.
- A plan for what the first draw must cover: payoff plus costs.
Frequently Asked Questions
Can I transfer my HELOC to a new lender?
Not directly. The new lender pays off the old line and you close it. That means a new application, a new valuation, and new underwriting.
Does the old lender need to approve the replacement?
Not for a new second lien on its own. The old lender only has to be paid and to file the release. If the new loan is a first lien, your existing first-mortgage holder gets paid off too.
Do I need 20% equity?
There is no universal equity rule. On Lendmire’s network, an investment line caps at 70% CLTV. Your room is that ceiling minus every lien that remains, so equity alone does not decide it.
Will the draw period restart?
Yes. A replacement is a new line with a new draw period. Investment lines on the network use a 5-year draw and 25-year repayment.
What if the new value comes in lower?
The line shrinks at the same ceiling. If the maximum cannot cover the old payoff plus costs, you can bring cash, wait, or move to a DSCR cash-out, which sizes differently.
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. Call 828-256-2183.
A line that looked generous at its original value can shrink fast when a new lender prices the same property off today’s liens, so run the stack before you commit.
