The Quick Read: The best program for a single-rental owner depends on which property you pledge, how the rental is titled, and how much equity sits above the first mortgage, because on an investment property the network’s lines cap at 70% combined loan-to-value, require a 700 credit score, and top out at $500,000. Combined loan-to-value (CLTV) adds your existing mortgage and the new line together, then divides by the property’s value. That one number decides most single-rental files. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
- Leverage: an investment-property line tops out at 70% CLTV, and no credit tier lifts it higher.
- Credit: 700 is the floor on an investment line, and a 720 score does not raise the ceiling.
- Size: lines run from $25,000 to $500,000 on a rental.
- Title: the rental must sit in your own name or a revocable living trust, not an LLC.
- Alternative: if the rental is in an LLC or you want property-rent-based lender review, a DSCR cash-out refinance is the usual fallback.
Which Lane Are You In?
Owners of a single rental have three realistic lanes: a line on the rental, a line on their own home, or a rent-qualified cash-out refinance. “Best” means the lane that matches your title, equity, and income. No single product wins for everyone.
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.
Lane one is a line on the rental itself. A home equity line of credit (HELOC) is a revolving credit line secured by property equity. You borrow, repay, and borrow again during a set draw period. On a rental, the lender looks at your personal income, your credit, and the property.
Lane two is a line on your primary residence, with the money used for the rental’s repairs or a down payment on another property. The collateral is your home. The lender underwrites it as an owner-occupied file, which opens higher leverage than an investment line allows.
Lane three is a rent-qualified cash-out refinance. This is a DSCR loan. DSCR stands for debt service coverage ratio, which compares the rent to the full monthly housing payment (principal, interest, taxes, insurance, and any HOA dues, together called PITIA). The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It replaces your first mortgage instead of sitting behind it. The complete DSCR loans guide walks through how that works.
Lendmire is a mortgage broker, not a lender. It places files with a network of wholesale HELOC lenders and DSCR lenders, so the program that fits depends on your situation. That is why a single “best” name does not exist, and why this article describes how the programs work instead of ranking companies.
How Underwriting Treats a Single Rental, Step by Step
A lender looks at one rental as both your whole portfolio and the only collateral. That makes the file simpler, but it leaves no cushion if something goes wrong. Here is the order most reviews follow.
1. Eligibility of the property. Is it a single-family home, a 2-4 unit building, a townhome, a PUD, or a condo? Is it listed for sale? Is it in a state the program serves?
2. Eligibility of the title. Is the rental held by you personally or in a revocable living trust? An LLC stops the file here.
3. Credit. On an investment line the network floors at 700. The lender uses a single-bureau score tied to the primary wage earner, and the report can be no more than 90 days old at closing.
4. Equity. The lender adds your existing mortgage to the requested line and tests the total against the 70% CLTV ceiling.
5. Income and debt. The lender caps your debt-to-income ratio (DTI) at 50% and reviews it around the interest-only payment calculated on the maximum draw, even if you plan to borrow less.
6. Valuation. Because an investment line cannot exceed $500,000, it normally runs an automated valuation with no traditional appraisal. A higher CLTV may call for a secondary valuation, and you can always ask for a full appraisal.
NerdWallet notes that HELOCs on investment properties are not offered by all lenders and that multiple appraisals may be required. On this network the line is stricter: the 70% CLTV ceiling means at least 30% of the value must stay unborrowed after the line closes.
The Equity Math, Without Dollar Signs
The ceiling is easiest to see in percentages. Say your first mortgage equals 45% of the rental’s value. A 70% CLTV ceiling leaves room for a line of up to 25% of value, subject to the $25,000 minimum and the $500,000 maximum.
Now say your first mortgage already sits at 68% of value. Only 2% of room remains. For most single-family rentals that is smaller than the $25,000 minimum line, so the file does not work.
Run a third case. Your rental is paid off. The full 70% of value is available as room, and the line can sit in first-lien position. The $500,000 cap then becomes the limit on a high-value property.
Credit does not stretch these numbers. On an investment property, 720 and 700 both reach 70% CLTV. A higher score buys nothing extra on leverage, and 700 is a hard floor with nothing beneath it.
What the Network’s Investment Line Looks Like
Here are the figures that define the investment-property line on this network. They are typical program ranges, subject to lender guidelines and full file review, and not a commitment to lend.
| Feature | Investment property line |
|---|---|
| Maximum CLTV | 70% |
| Minimum credit score | 700 |
| Line size | $25,000 to $500,000 |
| Lien position | First or second |
| Draw / repayment | 5-year draw, 25-year repayment |
| Drawn at closing | At least 75% of the line |
| Title | Individual or revocable living trust |
Three details deserve a closer look.
Most of the line is drawn on day one. At least 75% of the line must be drawn at closing. This is not a stand-by credit line that sits unused. If you only want a small cushion for repairs, the structure may not suit you.
The draw is interest-only, then it amortizes. During the 5-year draw you pay interest only. After that, the balance amortizes over 25 years, and the monthly obligation steps up because principal joins the payment. Experian describes market lines with draws of five to ten years followed by a 20-year repayment. The network’s investment line uses the 5-year draw and 25-year repayment, so confirm the exact structure before you compare offers.
Pricing floats and never becomes fixed. It moves through both the draw and the repayment period. Your payment can change even when you borrow nothing new. That matters if your rental runs on thin margins.
Structures and Variations Worth Knowing
First lien versus second lien. If you still owe on the rental, the line sits behind your mortgage as a second mortgage. If the rental is paid off, the line can take first position. The CFPB confirms that a home equity line on top of an existing mortgage counts as a second mortgage. Each lien position carries its own combined leverage test, so run your numbers both ways.
Investment line versus primary-home line. On the network, primary-residence and second-home lines can reach 90% CLTV, but only at a 720-or-better credit profile. That ceiling does not apply to a rental. If you use your home as collateral instead, you get more room, you put your home at risk, and the lender underwrites it as an owner-occupied file. The CFPB warns that falling behind on a HELOC could mean losing your home. That warning applies to every secured line, whichever property you pledge.
Line versus DSCR cash-out refinance. A line keeps your existing first mortgage and adds a second layer. A cash-out refinance replaces the first mortgage with a new one. The tradeoff is that you give up your existing first mortgage, and you take on a new 30-year structure. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
A few select lenders in the network offer coverage below 1.00 on DSCR loans, with leverage and terms adjusted. Many select programs start at 1.00. Clearing that number does not mean the rental produces positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. The investment property HELOC overview for single-rental owners goes deeper on the line side.
Where the General Rule Breaks
An LLC-held rental. The line must be titled to you personally or to 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. Retitling can affect your insurance, your existing mortgage terms, and your liability protection, so settle those questions before you move the deed.
A rental listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington. Taking a listing down does not fix the file right away.
Property types the line does not cover. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and properties on agricultural zoning are not eligible. Single-family homes, 2-4 unit buildings, PUDs, townhomes, and condos (including non-warrantable condos) are eligible.
Availability by state. Investment lines are available only in the 16 states where Lendmire offers full-service lending: Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia, and Washington. That is narrower than the DSCR footprint of 41 markets, including Washington, D.C. A Texas investment property qualifies as a non-homestead transaction, and Texas properties are limited to 10 acres.
A rough credit 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. With a 700 floor, most borrowers with those events behind them still have to rebuild first.
A small amount of equity. Below the $25,000 minimum, the line does not exist for that property. A DSCR loan has a different size range, so check that route before you give up on pulling equity.
Bank availability. Many big banks do not write investment-property lines at all. An investor in one BiggerPockets thread described calling banks that either did not offer the product or could not do it on an investment property. A broker who works with several wholesale lenders avoids that call-by-call search.
Decision Table: Choose by Your Situation
| Your situation | Likely best fit |
|---|---|
| Rental has a mortgage, titled to you | Second-lien investment line, if CLTV stays at or under 70% |
| Rental is paid off, titled to you | First-lien investment line |
| Rental is in an LLC | DSCR cash-out, or retitle first |
| Credit under 700 | Home-equity line on your residence, or DSCR cash-out |
| Need more than $500,000 | DSCR cash-out; investment lines cap at $500,000 |
| Want rent to carry the qualification | DSCR cash-out |
Keep one more factor in mind. Many investors with several mortgages and modest salary income find that the rent-based path is the only one that works, since personal DTI limits bind a line much harder than a DSCR loan.
The Risks of Borrowing Against Your Only Rental
Pledging your single rental concentrates your risk. If the tenant leaves and the unit sits empty, the line still bills you, and the rental is the asset a lender can take.
The main risks are these:
- Payment step-up. Interest-only payments flatter your cash flow during the draw. When repayment begins, principal joins the payment. Some lines also end in a balloon payment, which means the whole balance comes due when the draw period ends. Confirm the program’s repayment structure in writing.
- Floating pricing. Because pricing never converts to fixed, your payment can rise while the rental’s rent stays flat.
- Frozen draws. The CFPB notes that a lender may limit further draws if your home’s value falls significantly. Treat the available balance as conditional.
- No portability. Equity in one rental does not move to the next deal. Whatever you buy with the line still has to clear its own underwriting.
Tax treatment varies; consult a qualified professional.
Key Terms Defined
HELOC: A revolving credit line secured by property equity, with a draw period and a repayment period.
CLTV (combined loan-to-value): Your existing mortgage plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line, which on the network’s investment line lasts 5 years and is interest-only.
Lien position: Whether the line sits first in line to be repaid (first lien) or behind an existing mortgage (second lien).
DSCR: Debt service coverage ratio, meaning rent divided by the full monthly housing payment.
Vesting: How the property’s title is held, such as in your name, a revocable living trust, or an LLC.
What to Prepare Before You Apply
- A current mortgage statement for the rental, or proof it is paid off.
- Proof of ownership showing who is on title.
- Your income documentation under the applicable program, subject to lender guidelines.
- A credit profile that can support a score of 700 or better on a recent report.
- A clear plan for the funds, and a stress test showing the rental can carry the payment after the draw period ends.
Order matters here. Check your title first, then your combined leverage, then your credit. Most single-rental files fail on one of those three, and the fix for each is different.
Frequently Asked Questions
Can I get a HELOC on just one rental property?
Yes, on an investment property the network can place a line of $25,000 to $500,000, up to 70% CLTV, with a 700 minimum credit score. The line can sit behind your mortgage or in first position on a paid-off rental. Approval depends on lender guidelines, credit, title, and property review.
Can my LLC hold the line?
No, the line must be titled to you or to a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on this product. A rental already in an LLC usually needs a vesting change or a DSCR cash-out refinance, subject to program terms.
Will I need an appraisal?
Usually not. Investment lines cannot exceed $500,000, so they ordinarily run an automated valuation instead of a traditional appraisal. A higher CLTV may require a secondary valuation, and you can request a full appraisal at any time.
Is the line or a cash-out refinance better for one rental?
It depends on what you hold now. A line keeps your existing first mortgage, caps at 70% CLTV on an investment property, and carries floating pricing. A DSCR cash-out replaces the first mortgage, reaches about 75% LTV on a standard rental, and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Is my rental or my home at risk?
Whichever property secures the line is at risk. A line on the rental puts the rental on the table. A line on your primary residence puts your home on the table. Many investors choose the rental as collateral precisely to protect the home.
