The Quick Read: The best program for your situation is a standalone line of credit that sits behind your existing mortgage, leaves that loan’s rate and term alone, and fits your property type, credit profile, and combined leverage. On a rental, few lenders write this product, so the match matters more than the brand. Which program fits depends on occupancy, title, and how much equity you hold.
- A line in second position is a separate loan. Your first mortgage keeps its rate, term, and payment.
- On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score, subject to lender guidelines.
- The title must sit in your own name or a revocable living trust. An LLC cannot hold it.
- Your first mortgage’s rate does not add borrowing room. Only a smaller first balance does.
- If the property sits in an LLC or you need a large lump sum, a cash-out refinance is often the better tool.
Do You Have to Refinance to Get a HELOC?
No. A home equity line of credit (HELOC) is a separate loan secured by the same property. It is a second mortgage, paid in addition to your first one. Your first mortgage keeps its rate, its term, and its payment.
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.
A cash-out refinance works the other way. It replaces your first loan with a new, larger one, and the new terms apply to the whole balance. If your current mortgage is worth keeping, that difference drives the decision.
The catch is availability. On a rental, a HELOC is rare, not impossible. Many big retail lenders simply don’t write them. Small local banks sometimes route the request through a commercial line of credit instead, as BiggerPockets’ Rookie Reply episode discusses. A no from a large bank usually reflects product policy, not weak credit.
Lendmire is a mortgage broker, not a lender. It shops a network of wholesale HELOC lenders and matches the scenario to a program. The programs described below are the ones it places files with, and every figure is subject to lender guidelines and a full file review.
What Does “Best” Mean for a Program?
“Best” depends on the file. A program that is perfect for a primary-home owner with a 720 score can be useless for a rental held in an LLC. Score programs against your own situation using these criteria.
| Criterion | What to check |
|---|---|
| Occupancy | Primary, second home, or investment |
| Title | Individual or revocable trust vs. LLC |
| CLTV ceiling | Your first balance plus the line, divided by value |
| Credit floor | Varies by occupancy and tier |
| Valuation | Automated value vs. full appraisal |
| Draw structure | Length of interest-only draw and repayment |
| Property type | Unit count, condo status, exclusions |
Run your property through that list before you compare anything else. Most mismatches show up in the first three rows.
How Underwriting Treats a Line on a Rental, Step by Step
A bank-style investment line is underwritten mainly on you, the borrower. Here is the sequence a lender follows.
1. Occupancy is set. Primary, second home, and investment lines carry different ceilings. Investment is the tightest.
2. Title is checked. The property must be held by you personally or in a revocable living trust. This is where many rental files stop.
3. Credit is pulled. The network uses a single-bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing.
4. Combined leverage is calculated. Take the property value, apply the CLTV cap, and subtract every existing lien. What remains is the maximum line.
5. Value is confirmed. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal. A higher CLTV may call for a secondary valuation. You can also request a full appraisal.
6. Debt-to-income is tested. The ceiling is 50%, and 45% for scores from 600 to 679. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
7. Property eligibility is confirmed. Type, unit count, and condition must fit the program.
NerdWallet reports that investment-property lines usually want a credit score of 720 or higher and at least 20% equity, and that multiple appraisals may be required. The White Coat Investor lists proof of tenants and a debt-to-income ratio of 50% or less among typical requirements. Those are market-wide figures. On the network, an investment line starts at a 700 credit score, tops out at 70% CLTV, and carries the same 50% debt-to-income ceiling.
The Network Numbers by Occupancy
Occupancy sets the ceiling, so never read one row as if it described another. These are typical program ranges, subject to lender guidelines.
| Occupancy | Credit floor | Max CLTV | Max line |
|---|---|---|---|
| Investment property | 700 | 70% | $500,000 |
| Second home | 640 | 90% at 720+ | $500,000 |
| Primary residence | 600 | 90% at 720+ | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
Two notes keep that table honest. The 90% figure exists only at a 720-or-better credit profile, and it applies to lines up to $500,000. On a primary residence, a line above $500,000 requires a score of 700 or better (720 on the longer-runway structure described below). It also caps at 75% CLTV and requires a full appraisal. Lines above $500,000 are primary-residence only.
For a rental, the picture is simple. The ceiling is 70% CLTV, and no tier sits above it.
How Much Room Do You Actually Have?
Room comes from arithmetic, not from your first loan’s rate. Here is a worked example in percentages only. These inputs are modeled assumptions, not market data.
- Assume your rental’s first mortgage balance equals 50% of its value.
- The investment-property ceiling is 70% CLTV.
- Your maximum line is the gap: 20% of the property’s value.
Now imagine you pay that first mortgage down to 40% of value. The gap grows to 30%, but the 70% cap still binds. The terms of the first loan change none of this. Only a smaller balance or a higher value adds room.
The credit tier matters too. A borrower below the 700 floor doesn’t get a smaller investment line. That borrower is outside the investment program entirely.
Draw Periods, Repayment, and Payment Shock
A HELOC is an “open-end” line you can borrow against repeatedly, as the CFPB’s HELOC guidance explains. That guidance is written for owner-occupied homes, so use it for mechanics only. It notes that the draw period could last 10 years, that payments are often significantly higher in repayment, and that a lender can stop further draws if the home’s value drops significantly.
The network’s structures follow the same pattern with fixed terms. A primary residence or second home can run one of two designs:
- Shorter-draw structure: a 3-year interest-only draw, then a 17-year fully amortizing repayment.
- Longer-runway structure: a 5-year interest-only draw, then a 25-year fully amortizing repayment.
An investment line runs the longer-runway structure only. In both designs, at least 75% of the line is drawn at closing. Pricing floats through the draw and the repayment period and never converts to fixed.
That has two consequences. This is not a mostly-empty safety net, since you take most of it on day one. And the payment will step up when the draw ends. Stress-test the property at the repayment payment, not the interest-only payment. A rental that works today can be tight in year six.
Where the General Rule Breaks
The mechanics above hold for most files. These edge cases are where they fail.
LLC title. Bank-style lines generally cannot lend to an entity. On the network, LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change or a different product, such as a DSCR cash-out refinance, subject to program terms.
Property type. Eligible types include 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. Modular factory-built homes are eligible on the longer-runway structure only. A 2-4 unit property needs a 640 minimum on that structure.
Exposure limits. A borrower is limited to three lines in total. A borrower who owns more than 15 financed properties is not eligible.
Listings. A property listed for sale, or listed within the past 60 days, is ineligible in some states. Ask before you list or relist.
Geography. Lendmire’s HELOC lending runs through 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 its DSCR loan footprint of 41 markets, including Washington, D.C. Some of those states carry their own overlays on leverage or draw terms.
The label problem. “DSCR HELOC” is a market label, not a regulated product category. It can mean a revolving line, a closed-end second, or a cash-out refinance. A closed-end second is a lump sum that amortizes right away. Ask which product you are actually being offered, and where it sits in lien order.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history is handled differently on different programs, and one declines it regardless of age.
Will Your First Mortgage Allow It?
Usually, but read your note. Check these items before you apply:
- Whether the loan documents allow a subordinate lien.
- Whether your current servicer offers lines on rentals at all. Many don’t, and that has no bearing on your standing.
- Your first mortgage’s current balance, since the new lender will verify it.
- Whether you plan to refinance the first mortgage later. A new first lender will generally want your line either paid off or placed behind it, so ask both parties before you commit.
HELOC or Cash-Out Refinance?
Pick based on the size of the need, the title, and the value of your first loan.
| Choose this if… | HELOC (second position) | Cash-out refinance |
|---|---|---|
| Your first mortgage is worth keeping | Yes | No |
| You need a large lump sum | Rarely | Often |
| The property sits in an LLC | No | Yes (DSCR) |
| Your income is hard to document | Depends on program | Often |
| You want to borrow in stages | Partly, with 75% drawn up front | No |
The cash-out route deserves a plain description. On standard rentals, a DSCR cash-out refinance typically tops out around 75% LTV, and lenders commonly expect about 6 months of seasoning. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A coverage ratio of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Most programs want a score around 660, and 700 or better unlocks the strongest leverage. The complete DSCR loans guide walks through the full qualification picture.
A self-employed investor might also ask whether a bank statement option can fund the next rental. Lendmire’s piece Best Bank Statement HELOC Program Without Refinancing Your First Mortgage covers that path.
Another route is worth knowing. Many investors draw on the line against their own primary residence to fund rentals. The lender then focuses on the home as collateral, and the rental ceiling doesn’t apply. That path has its own risks, because it puts your home behind the investment.
Risks and Trade-Offs
Stacked leverage. A second lien raises total debt on the property. If values fall, your equity cushion shrinks, and a lender can freeze draws.
Two payments. The line adds a payment to the property’s cash flow. If the next deal uses a DSCR loan, whether this payment enters that loan’s coverage calculation depends on the program.
Coverage is not cash flow. A DSCR compares rent to the monthly principal, interest, taxes, insurance, and any HOA dues. Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside that math.
Floating payments. The line never converts to fixed, so the payment moves with the market.
A BRRRR plan still needs an exit. Using the line for a down payment and rehab only defers the payoff. You still need a later refinance or sale to retire it.
Key Terms Defined
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value.
Second lien: A loan secured by the same property that gets paid after the first mortgage if the property is sold or foreclosed.
Draw period: The stretch when you can borrow from the line, usually paying interest only.
Repayment period: The stretch after the draw ends, when the balance amortizes and payments rise.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s monthly debt service, which shows whether rent covers the payment.
Vesting: The legal form in which the property is titled, such as an individual, a trust, or an LLC.
Frequently Asked Questions
Can I get a HELOC on a rental property without touching my first mortgage?
Yes, through a lender that writes standalone lines in second position. On an investment property, the network ceiling is 70% CLTV with a 700 minimum credit score, subject to lender guidelines. Your first mortgage’s rate, term, and payment stay as they are.
Do the terms of my first mortgage increase how much I can borrow?
No. Borrowing room is set by the property’s value, the CLTV cap, and your first loan’s balance. The pricing on that first loan has no effect. Only paying the balance down, or a higher valuation, adds room.
Can my LLC take out a HELOC?
Not on these programs. An LLC cannot hold title on the network’s lines. If the rental is already in an LLC, the options are a vesting change or a DSCR cash-out refinance, subject to program terms.
How much can I borrow, and what documentation is required?
An investment line runs from $25,000 up to $500,000 on the network. Lines at or below $500,000 ordinarily use an automated valuation, though you can request a full appraisal. Debt-to-income can run to 50%, tested on the interest-only payment at the maximum draw.
When does a cash-out refinance make more sense?
Choose it when you need a large lump sum, when the property is held in an LLC, or when your first mortgage isn’t worth keeping. A HELOC fits better when you want to protect a low first-mortgage rate and your title and leverage fit the program.
