The Quick Read: The best program for your situation is usually a standalone second-lien equity line on the rental, which sits behind your existing mortgage, leaves that loan as written, and, across the wholesale network Lendmire works with, reaches 70% combined loan-to-value up to $500,000 for borrowers with a 700 score or better. Every figure is subject to lender guidelines and full file review. Few lenders write this product, and the ones that do underwrite you, not the rent.
- Lien position: the line sits second behind your first mortgage, so the first loan keeps its balance, term, and payment.
- Leverage: on an investment property, the network ceiling is 70% combined loan-to-value, and the line tops out at $500,000.
- Credit: 700 is a hard floor, and 720 buys no extra leverage.
- Title: the property must be held by you personally or in a revocable living trust, not an LLC.
- Catch: the first mortgage still counts. It eats into your equity room and your debt ratios.
What Does “Without Touching Your First Mortgage” Actually Mean?
It means a second lien. You keep the loan you have. A new lender records a separate loan behind it, secured by the same rental. If the property were ever sold or foreclosed, the first lender gets paid first and the second lender gets what is left.
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 structure matters when your current mortgage is one you would rather keep. A cash-out refinance replaces the whole first loan and reprices the entire balance, not just the new cash. A line leaves the old loan alone and prices only the money you take.
Here is the part most people miss: “untouched” is not the same as “ignored.” Your first mortgage balance sets how much equity is left to borrow against. It also shows up in your debt ratios. The line sits next to the first mortgage in the file, not outside it.
Supply is the other reality. NerdWallet notes that a HELOC on an investment property is not offered by all lenders and carries strict qualification requirements. That matches what a broker sees daily. Large retail lenders mostly skip rental collateral. A broker’s value here is knowing which wholesale lenders write rental seconds and matching your file to one.
Key Terms Defined
HELOC (home equity line of credit): a revolving line you can draw on repeatedly, up to a set limit, secured by property equity.
Second lien: a loan recorded behind your first mortgage that gets repaid second if the property is sold or foreclosed.
Combined loan-to-value (CLTV): your first mortgage balance plus the new line, divided by the property’s value.
DSCR (debt service coverage ratio): a rent-versus-payment test used on investor loans, where the rental’s income is compared to its monthly obligation.
Draw period: the stretch when you can borrow and typically pay interest only.
Vesting: how title is held, such as an individual, a trust, or an LLC.
How Much Line Can Your Equity Support?
Start with the property’s value, multiply by the CLTV ceiling, and subtract everything already recorded against it. The remainder is the most the line can be, and the $500,000 cap sits on top of that. On a rental in this network, the ceiling is 70% CLTV. Run three cases in percentages:
- Roomy: your first mortgage is about 40% of value. That leaves about 30% of value as potential line, until you hit the $500,000 cap on a high-value property.
- Tight: your first mortgage is about 65% of value. Only about 5% of value is left, and that may fall under the $25,000 minimum line, so there may be no usable line at all.
- No room: your first mortgage is at or above 70% of value. There is nothing to borrow against. A recent purchase with a high-leverage first loan lands here.
A larger line does not widen the ceiling. A better score does not either. Investment lines have two credit tiers, 720 and above and 700 and above, and both reach the same 70%. Credit above 700 buys comfort, not leverage.
Valuation is usually light. Because an investment line caps at $500,000, and full appraisals are required only above that, these lines ordinarily run on an automated valuation with no traditional appraisal. A higher CLTV may call for a second valuation, and you can always request a full appraisal.
How the Line Works After Closing
The line follows the draw-and-repay pattern the Consumer Financial Protection Bureau describes for home equity lines: you borrow repeatedly during a draw period, then you stop borrowing and repay the balance. Payments often jump when repayment starts.
On the investment lines in this network, the structure is fixed:
- A 5-year interest-only draw period, then a 25-year fully amortizing repayment.
- At least 75% of the line is drawn at closing.
- Later draws start at $1,000 (some states set a higher minimum).
- Pricing floats through both the draw and repayment periods and never converts to fixed.
That last point is a real difference. Some home equity plans let you lock part of a balance. This one does not. The CFPB’s HELOC brochure also stresses that with variable pricing, your payment can change even when you draw nothing new.
Vacancy is the other quiet risk. The line payment does not pause when the unit is empty. Budget for it as a fixed obligation.
Which Program Type Fits? A Side-by-Side
| Factor | Investment equity line | DSCR cash-out refinance | Line on your own home |
|---|---|---|---|
| First mortgage | Kept as is | Replaced | Kept as is |
| Reviewed on | You: credit, DTI, equity | Primarily the rent covering the payment | You |
| Collateral at risk | The rental | The rental | Your residence |
| Ceiling | 70% CLTV | About 75% LTV | 90% CLTV, only at 720+ |
| Title | You or revocable trust | LLC possible, per program terms | You or revocable trust |
The three products solve different problems. The investment line keeps your first loan and borrows against your personal profile. The DSCR cash-out replaces the first loan and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The home-based line moves the risk to the house you live in, which is a trade many investors decide against. The 90% ceiling applies only to primary residences and second homes at a 720-or-better credit profile. It never applies to a rental.
Cash-out typically also carries about six months of seasoning, so a rental you just bought or refinanced may need to wait.
What Lenders Review on an Investment Line
Because this line qualifies you rather than the rent, the file looks more like a personal loan application than a DSCR file. Across the network, these are the points that decide it:
- Credit: 700 minimum on an investment property. The scoring uses one bureau, keyed to the primary wage earner. The report can be no more than 90 days old at closing, and there are no rescores.
- Debt-to-income: up to 50% at most. The line is tested on the interest-only payment calculated on the maximum draw, not on what you actually drew. A big undrawn line still counts against you.
- Market comparison: NerdWallet reports that bank-style investment lines typically want about a 720 score and a debt-to-income ratio between 40% and 50%. The network figures above are the ones that apply here.
- Property: single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
- History: 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.
- Exposure: a borrower can hold up to three lines and cannot own more than 15 financed properties.
- Listing status: a property listed for sale, or listed within the past 60 days, is ineligible in some states.
Availability is narrower than Lendmire’s DSCR footprint of 41 markets. The equity line is brokered in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.
Where the Rule Breaks: Edge Cases
Your rental is in an LLC. This is the sharpest edge. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title on this line. Your options are a vesting change or a DSCR cash-out refinance, which can work for entity-held property, subject to program terms.
Your first mortgage has restrictive language. Some notes and deeds of trust limit additional liens or carry due-on-sale language. Read yours before you apply. Check your note and deed of trust, because that is a verification item, not an afterthought.
You need more than $500,000. Lines above $500,000 exist only on primary residences, at 75% CLTV with a full appraisal. They are never available on a rental.
You want to use the line for the next purchase. That works, but it is two separate approvals. The line does not close a purchase for you, and the payment on the new loan is judged on the new property’s own numbers. The line payment is tested against your personal debt ratios, not the new property’s coverage ratio.
You assume DSCR clears everything. A DSCR above 1.00 tells you rent covers the mortgage payment. It does not mean positive cash flow, since repairs, vacancy, management, utilities, and capital costs sit outside that calculation.
Funding the Next Rental With a Line
A line is a good fit for needs that arrive in stages, like rehab draws, or for a down payment and reserves on the next deal. A cash-out suits one big lump sum.
Picture an investor with a rental that has a low-leverage first mortgage and a purchase contract on another property. The line supplies the down payment. The new purchase then runs through its own financing. Most purchase files in the network land at 75% to 80% LTV, and select high-leverage programs reach 85% with roughly a 700-plus score, all subject to lender guidelines.
Watch the stacking. Borrowing the down payment can push your effective leverage on the new property very high. Both the new loan and the line must be serviced from rents and income. If the new property is a straight rental, the complete DSCR loans guide walks through how that purchase loan is tested. Lendmire’s explainer Best Investment Property HELOC Program Without Restarting Your Mortgage Term covers the other side of the strategy.
Which Route Fits Which Situation?
| Your situation | Likely route | Why |
|---|---|---|
| Good first loan, 700+ score, equity room | Investment equity line | Keeps the first loan, borrows only what you need |
| Rental held in an LLC | DSCR cash-out refinance | LLCs cannot hold title on the line |
| First loan is not worth keeping | DSCR cash-out refinance | Replacing it costs less than a stacked second |
| Little equity after the first loan | Neither yet | The 70% CLTV ceiling leaves nothing to borrow |
| Need a single large lump sum | Cash-out refinance | A line suits staged needs, not one big draw |
Pre-Application Checklist
Gather these before you talk to a broker:
1. Current value estimate and first mortgage balance.
2. Mortgage statement and a copy of your note and deed of trust.
3. Title and vesting details.
4. A recent credit report and a debt list.
5. Lease or rent schedule and insurance declarations.
Then ask any lender or broker:
- Is the line a first or second lien here?
- Are you tested on the full line or the drawn amount?
- Does the pricing ever convert to fixed?
- What happens to the line if I later refinance the first mortgage?
Frequently Asked Questions
Can I get a HELOC on a rental that still has a mortgage?
Yes, through select lenders. The line is recorded as a second lien behind your first. On this network, investment lines reach 70% CLTV with a 700 minimum credit score, subject to lender guidelines. The first mortgage balance reduces your available equity.
Will it change my first mortgage?
No. The first loan keeps its balance, term, and payment. It still counts in your debt ratios, and the line must still sit within the combined loan-to-value ceiling.
Can an LLC-owned rental qualify?
Not for this line. Title must be held by you individually or by a revocable living trust. An LLC-owned rental usually points to a DSCR cash-out refinance, depending on program guidelines.
What happens if I refinance the first mortgage later?
The new first lender will generally require the line to stay behind it or be paid off, so plan that sequence early. Check how your lenders treat the subordination before you commit.
Why do so many lenders decline?
Rental collateral carries more risk for a second lender, and many depository lenders skip it entirely. A broker that shops several wholesale lenders can match your credit, equity, and title to the few that write it.
