The Quick Read: A landlord holding a cheap first mortgage can borrow against a rental’s equity with an investment property HELOC and leave that mortgage alone. On Lendmire’s wholesale network, an investment line tops out at 70% combined loan-to-value. It is underwritten on you, not on the rent.
- Ceiling: 70% CLTV on an investment property, with a 700 minimum credit score and lines from $25,000 to $500,000, subject to lender guidelines.
- Structure: a 5-year interest-only draw followed by a 25-year repayment, with pricing that floats and never converts to fixed.
- Draw at closing: at least 75% of the line is drawn when you close.
- Title: an individual or a revocable living trust must hold the property. An LLC cannot.
- Alternative: a DSCR cash-out refinance replaces the first mortgage, up to 75% LTV on a standard rental, and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
If you have owned a rental for years, your first mortgage may be the best financing you will ever hold. Replacing it to get cash can cost you that advantage. This article shows how a HELOC works around the problem, where it breaks, and when replacing the loan is the smarter move.
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.
What Is an Investment Property HELOC?
An investment property HELOC is a revolving line of credit secured by a rental. You borrow what you need during a draw period, then repay over a set term. It sits beside your first mortgage instead of replacing it. Lenders treat it as riskier than a primary-home line, so it is harder to find and usually smaller.
NerdWallet says the lender pool for rental-property lines is smaller. It also says you usually can’t borrow as much as against a primary home. The reason is simple. Lenders see higher default risk on rentals, because borrowers tend to protect their own home first.
Two different products hide under one name. One line is secured by the rental itself. The other is secured by your primary home and used to fund rental activity. This article covers the first kind.
Lendmire is a mortgage broker. It does not lend. It arranges these lines through select wholesale partners, and every figure below is subject to lender guidelines and full file review. The HELOC product is available only in Lendmire’s 16 full-service states (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA). That is narrower than its DSCR investor-loan footprint, which spans 41 markets, including Washington, D.C.
Key Terms Defined
HELOC: a home equity line of credit. You draw cash as needed up to a limit, and you pay on what you have drawn.
CLTV (combined loan-to-value): your first mortgage plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow. Payments are interest-only.
Repayment period: the stretch after the draw ends. Principal starts to amortize, so payments rise.
Lien position: where a loan stands in line to be repaid if the property is sold. A first lien is paid first. A second lien is paid after.
Subordination: a lender agreeing to stay in second place behind another loan.
DSCR (debt service coverage ratio): monthly rent divided by the full monthly housing payment: principal, interest, taxes, insurance, and any HOA dues.
PITIA: that full payment, spelled out as principal, interest, taxes, insurance, and association dues.
Seasoning: the waiting period a lender wants between buying a property and borrowing against it.
Vesting: how title is held, such as in your own name, in a trust, or in an LLC.
Why a Low First Mortgage Changes the Math
A low first mortgage helps twice. It is cheap to keep, and it leaves room under the combined-leverage cap. A cash-out refinance throws away both. A HELOC keeps both, at the price of a floating line, a thinner lender pool, and personal-income underwriting.
Yahoo Finance describes the lock-in effect: owners holding cheap mortgages rather than giving them up. Landlords feel it more than most, because the loan is attached to an income property.
The cleanest mental model is add versus replace.
| Factor | Keep first + HELOC | Replace with cash-out |
|---|---|---|
| What reprices | Only the line | The whole balance |
| Underwritten on | You (credit, DTI) | Rent coverage |
| Title | Individual or revocable trust | LLC possible* |
| Payments | Interest-only, then amortizing | Fully amortizing |
| Size cap | $500,000 total | Up to $3,000,000 |
| Best fit | Smaller, staged cash needs | Large cash needs, weak first loan |
*Subject to lender program eligibility.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. Lendmire’s complete DSCR loans guide covers that side in full.
How Underwriting Actually Treats the Line, Step by Step
An investment HELOC is underwritten on your personal file. The lender looks at your credit, your debt-to-income ratio, and your equity. It does not ask whether rent covers a payment. That is the sharpest contrast with a DSCR loan.
Here is the sequence a file follows.
1. Eligibility screen. On Lendmire’s network, an investment line needs a 700 minimum credit score. The score model keys off the primary wage earner, and the credit report can be no more than 90 days old at closing. Bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history follows a 7-year path for a foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale.
2. Property screen. Eligible types include single-family homes, 2-4 units, PUDs, townhomes, and condos, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
3. The equity math. Take the lender’s CLTV cap, apply it to the appraised value, and subtract what you owe on the first mortgage. What remains is the potential line. The CFPB’s HELOC booklet walks through the same subtraction. On an investment property here, the cap is 70% CLTV. Credit above 700 does not raise it. Both the 700 and 720 tiers sit at 70%, so extra score buys eligibility, not leverage.
4. The income test. The maximum DTI is 50%, and the lender tests it against the interest-only payment calculated on the maximum draw. Not on what you plan to draw. On the maximum. Lenders generally consider documented lease income as part of the picture, subject to guidelines. Market surveys, such as the one NerdWallet cites, put typical DTI limits between 40% and 50%. The network figure is 50%.
5. Valuation. Because an investment line caps at $500,000, and full appraisals begin only above that, the file uses an automated valuation. Many close with no traditional appraisal. You can still request a full appraisal.
6. Documents. Expect an application, credit and income documents, a lease or rent history, your existing mortgage statement, and title and vesting records.
A Worked Example in Percentages
Take a rental with a low first mortgage. Say the balance is 40% of the property’s value. The 70% CLTV ceiling leaves room for a line of up to 30% of value. If you draw 25% of value, your combined leverage lands at 65%.
Now look at the blend. Of all the debt on the property, about 60% is still your cheap first mortgage. Only about 40% is floating. Replace the first mortgage with a cash-out and 100% of the debt reprices at today’s market.
The picture flips in three cases:
- The gap between your old loan and new pricing is small. Then the rate advantage you protect is thin.
- The draw is big compared with the first mortgage. Then the floating share dominates.
- You need more than 70% CLTV or more than $500,000. The line can’t deliver that.
Now a thinner-equity case. Say the first mortgage is 60% of value. The line room is only 10% of value, and the $25,000 minimum line may not even fit on a modest property. Not ideal. This is where a cash-out, with a ceiling of 75% LTV on a standard rental, often works better.
How the Line Behaves After Closing
On the network’s investment lines, the draw runs 5 years, interest-only. Repayment then runs 25 years, fully amortizing. At least 75% of the line is drawn at closing. Pricing floats through both periods and never converts to fixed.
That last detail matters. The CFPB notes that some lines let you convert part of the balance to a fixed rate. That option is not part of these investment lines. NerdWallet describes a typical market structure as a 10-year draw and up to 20 years of repayment. Lendmire’s investment line is a 5-year draw and 25-year repayment instead. A figure quoted to you always belongs to its own structure.
Two behaviors surprise landlords:
- The step-up. When repayment begins, principal joins interest. The payment jumps. It is a good idea to size the line against your cash flow after that jump, not during the interest-only years.
- Floating exposure. Your payment can change even if you borrow nothing more. A rent increase may or may not keep pace.
Stress-test it. Ask what your coverage looks like if pricing moves up and the amortizing payment arrives. Do not assume the interest-only years last.
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.
Where the General Rule Breaks
The standard path is simple: an individual owns a rental, has a 700+ score, and draws on the line. These cases bend it.
The LLC problem. An investment line cannot be vested in an LLC, a corporation, a partnership, or an irrevocable, blind, or land trust. Only individuals and revocable living trusts can hold title. If your rental is already deeded to an LLC, you need a vesting change or a DSCR cash-out instead. A re-deed can change your liability separation. Talk to an attorney first. DSCR loans can close in LLC names, subject to lender program eligibility.
Subordination on the first mortgage. A line placed behind your first lien requires that the first lender’s documents allow subordinate financing. If you later refinance the first, the line holder must agree to stay in second place. Some won’t. Check this before you draw.
Exposure limits. A borrower can hold three lines at once. Combined exposure caps at $750,000 on one program and $2,000,000 on another. Borrowers with more than 15 financed properties are not eligible. Scaling landlords can hit these limits sooner than they expect.
Clearing 1.00 coverage is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation. A rental can clear the ratio and still lose money in a bad year.
The label “DSCR HELOC.” It is a market label, not a standard product. It can mean a rent-qualified second lien, a rent-qualified cash-out refinance, or a personal-income line. Ask what is being underwritten: you or the property.
Line suspension. Lenders can freeze or reduce a line in certain situations. The CFPB booklet covers this in general terms. Don’t count on unused line room as an emergency fund.
Which Landlord Are You?
| Your situation | Likely better fit | Why |
|---|---|---|
| Cheap first, deep equity, small staged needs | HELOC | Keeps the first, reprices only the draw |
| Cheap first, thin equity | Cash-out or wait | Line room may be too small |
| Property held in an LLC | DSCR cash-out | Line can’t be LLC-vested |
| Need above $500,000 | DSCR cash-out | The investment line caps at $500,000 |
| Weak personal DTI, strong rent | DSCR cash-out | Qualifies primarily on rent coverage |
On the DSCR side, most files land at a cash-out ceiling of 75% LTV on a standard rental, and 70% on short-term-rental collateral. Seasoning of about 6 months is the common expectation. Coverage of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Reserves vary by lender, leverage, and loan size. Around 6 months of PITIA is common.
In Lendmire’s experience placing both products, the call usually turns on two questions. How big is the gap between your first mortgage and today’s market? And does the cash need to arrive all at once? A big gap and a small need point to a HELOC. A small gap and a big need point to replacing the loan. Honestly, the borderline cases are a genuine toss-up, and running both side by side is the only real answer.

What to Bring to a Broker
A short pre-application checklist saves time:
- Your current mortgage statement, with balance and any restrictions on second liens.
- A credit report less than 90 days old at closing, from the primary wage earner.
- Current leases or rent history.
- Proof of how title is held, and your trust documents if applicable.
- A list of your financed properties, since the count affects eligibility.
- Your target draw size and the date you need the money.

Frequently Asked Questions
Can I get a HELOC on a rental property?
Yes, though fewer lenders offer it. On Lendmire’s network, an investment line is available through select wholesale partners in 16 states. It requires a 700 minimum credit score, caps at 70% CLTV, and runs from $25,000 to $500,000. Terms are subject to lender guidelines and full file review.
Will a HELOC keep my low first mortgage in place?
Yes, it can. The line sits in first or second lien position as a standalone loan, so your existing mortgage stays untouched. The catch is that your first lender’s documents must allow a second lien. A later refinance of the first also needs the line holder to subordinate.
Does the line convert to a fixed payment later?
No. Pricing on the network’s investment lines floats during both the draw and the repayment period. It never converts to fixed. Some lines elsewhere offer a fixed-rate conversion, so ask what a quoted figure is attached to.
Can my LLC-owned rental get a HELOC?
Not directly. Title must be held by an individual or a revocable living trust. An LLC-held property needs a vesting change first, or a DSCR cash-out refinance instead, which can close in an LLC name subject to lender program eligibility.
Is a HELOC better than a DSCR cash-out refinance?
Neither wins every time. A HELOC suits smaller, staged draws against deep equity, with your first mortgage left intact. A DSCR cash-out suits larger needs, LLC-held properties, and borrowers whose rental income is stronger than their personal DTI.
