The Quick Read: An investment property HELOC is a revolving line of credit secured by the rental house itself, sized from the home’s value, a combined loan-to-value cap, and the mortgage balance already on it. On Lendmire’s wholesale network, the investment version caps at 70% combined leverage and a $500,000 line, and it is underwritten mostly on the borrower. Rent plays a smaller role. Here is what matters most:
- An investment line needs at least a 700 credit score, and a higher score does not raise leverage past 70% CLTV.
- Title must sit with an individual or a revocable living trust. An LLC cannot hold it.
- At least 75% of the line is drawn at closing, so it is not idle standby credit.
- Pricing floats through the draw and repayment periods and does not convert to fixed.
- A DSCR cash-out refinance is the usual alternative when the property is in an LLC or the borrower’s income is the weak spot. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
What Is an Investment Property HELOC?
An investment property HELOC is a line of credit that uses a non-owner-occupied house as collateral. The borrower draws against the line, repays, and draws again within the terms. It can sit in first lien position or behind an existing mortgage.
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.
The product is scarcer than a primary-home line. NerdWallet notes that not every lender offers one, that qualification is strict, and that it is harder to get than a primary-home line because lenders see higher default risk on rentals. Many large retail lenders skip rental lines altogether.
Lendmire is a mortgage broker, not the lender. It places equity lines with select wholesale partners, and every figure below is subject to lender guidelines and full file review. This product is also available in a narrower footprint than the DSCR platform. It runs in 16 full-service states, while DSCR investor loans cover 41 markets, including Washington, D.C.
One more distinction matters before the mechanics. “Rental HELOC” describes two different things. One is a line secured by the rental. The other is a line secured by the owner’s primary home and spent on a rental. This article covers the first. The second puts the family home at risk and follows different rules.
How Does Underwriting Treat the Line, Step by Step?
Underwriting for an investment line follows a fixed sequence: eligibility of the property and title, valuation, credit, debt-to-income, and then the line size. A file that fails an early step never reaches the later ones. Here is how the steps work.
1. Title and vesting. The borrower must hold title personally or through an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the first gate, and it ends many rental files.
2. Property type. A single-family house is eligible. So are 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, log homes, co-ops, condotels, and anything with commercial, mixed-use, or agricultural zoning are not offered.
3. Credit. An investment line has a hard 700 minimum with no tier beneath it. The lender pulls a single-bureau score keyed to the primary wage earner. The report must be no more than 90 days old at closing, and there are no rescores.
4. Credit history. Housing-history standards apply across every financed property the borrower owns. 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.
5. Debt-to-income. The maximum is 50%. The lender qualifies the borrower on the interest-only payment calculated on the maximum draw, not on the balance the borrower plans to use. A borrower who intends to draw lightly is still tested as if the line is fully drawn. NerdWallet reports that a 40% to 50% debt ratio is typical across the broader market, so 50% is the outer edge of that band.
6. Valuation. Because an investment line tops out at $500,000, and full appraisals are required only above that size, the line runs on an automated valuation. It commonly closes with no traditional appraisal. A borrower can still request a full appraisal, and a higher CLTV may call for a secondary valuation.
7. Exposure and listing status. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible. In several states, a property that is listed for sale, or was listed in the past 60 days, is ineligible.
The thread through every step is that the lender is underwriting the borrower. Rent matters mainly as support for the debt-to-income picture and the borrower’s overall capacity. The line does not qualify on the property’s coverage ratio the way a DSCR loan does.
Lendmire’s breakdown of the rules for an investment property line goes deeper on the eligibility tests.
How Is the Line Sized? A Worked Example in Percentages
The line equals the home’s value times the combined-LTV cap, minus every lien already on the property, and then it is held to the $500,000 ceiling. On the investment tier, the cap is 70% CLTV for both the 720+ and the 700+ credit tiers. Credit above 700 buys eligibility, not extra leverage.
Run it as percentages of value. Say the automated valuation lands at 100% of the home’s estimated value, and the first mortgage balance equals 40% of it. Take the 70% cap and subtract the 40%. The line can reach about 30% of value, subject to the $25,000 minimum line and the $500,000 maximum.
Now change one input. If the first mortgage sits at 60% of value, only 10% of value is left. A low valuation hits harder than most borrowers expect. If the automated value comes in 10% under the borrower’s estimate, the headroom shrinks far more than 10%, because the cap applies to the whole value while the mortgage stays fixed.
Two program details change how a borrower should think about the result:
- At least 75% of the line is drawn at closing. A borrower sizing a $200,000 line for standby capital will be borrowing most of it on day one. The “interest only on what you draw” benefit is real, but the closing draw requirement makes it smaller than the marketing language suggests.
- Later draws have a floor. After closing, the minimum subsequent draw is generally $1,000, stated by one wholesale program, and the line itself starts at $25,000.
Market surveys report that lenders commonly cap investment-property lines at 80% of value, per Experian. The network figure for an investment line is 70% CLTV, so a borrower comparing outside quotes against this network should expect less room.
What Happens When the Draw Period Ends?
When the draw period ends, the line stops lending and a fully amortizing repayment begins. On an investment line in this network, the draw period is 5 years of interest-only payments, followed by 25 years of principal and interest. Investment lines run this one structure only.
Bankrate explains that repayment follows an amortization schedule like a regular mortgage. For a landlord, that is the moment the monthly obligation steps up sharply. Principal starts to come out of the payment on top of the interest, and the pricing still floats. It never converts to a fixed term.
Think of two cash-flow tests, not one. The first is whether the rental covers the interest-only payment during the draw. The second is whether it covers the fully amortizing payment after year five, with pricing possibly higher than at closing. A borrower who passes only the first test is borrowing against a future squeeze. The stronger plan is to model the repayment phase before signing, and to decide in advance whether the exit is a paydown, a sale, or a refinance.
Structures and Variations
Most variation on this product comes from lien position, title, and property type, because the draw structure is fixed for investment lines.
Lien position. The line can be a standalone first lien on a rental that is paid off, or a second lien behind the existing mortgage. A second lien leaves the first mortgage untouched. That matters if the first mortgage carries terms the borrower does not want to lose.
Trust ownership. A revocable living trust can hold title and still qualify. This is the workaround for borrowers who want estate-planning structure without a business entity.
Unit count. A 2-4 unit property is eligible, but one wholesale program sets a 640 minimum score on multi-unit files. An investment line already requires 700, so the stricter investment floor controls.
Line size. Anything above the investment cap is reserved for primary residences, and it carries a full appraisal. A rental borrower therefore stays on the smaller, automated-valuation side of the product.
Business bank accounts. A 680 minimum applies to the deposit analysis. Investment lines already floor at 700, so bank-statement income is never the binding constraint here.
Where the General Rule Breaks
The general rule is that a borrower with equity and a 700 score can draw on a rental. These edge cases are where that rule fails.
The property is deeded to an LLC. This is the sharpest break. An LLC cannot hold title on an equity line. A rental already in an LLC needs a vesting change, or the investor moves to a DSCR cash-out refinance instead. DSCR loans to LLC-titled entities are available subject to lender program eligibility.
The borrower’s income is thin or irregular. Because the line is underwritten on the borrower, a self-employed owner with heavy write-offs can fail the 50% debt-ratio test even when the rental is strong. The property’s rent cannot rescue the file the way it can on a DSCR loan.
The value falls after closing. The Consumer Financial Protection Bureau notes that a line is open-end and that a lender may stop further draws if the home’s value drops significantly. Standby credit on a rental is only as stable as the valuation behind it.
The investor owns many properties. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible. Either limit can block a growing portfolio, so a larger investor should plan around both before relying on this product.
The borrower plans to use the line as a cash offer. Drawing on one rental to buy another leaves the new house unencumbered at first, and it leverages the old one. The exit is usually a refinance of the new property that pays the line down. If that refinance does not work, the borrower holds floating-price debt against two properties. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
The property type is off the list. Manufactured homes, log homes, and barndominiums are not offered, on either the equity line or the DSCR side.
Key Terms Defined
CLTV (combined loan-to-value): The total of all loans on the property divided by its value, including the new line.
Draw period: The window when the borrower can take money from the line, interest-only on an investment line for 5 years.
Repayment period: The stretch after the draw ends when the balance amortizes to zero, 25 years on an investment line.
Lien position: Whether the line gets repaid first (first lien) or after another mortgage (second lien).
Automated valuation: A computer-based estimate of the home’s value used in place of a full appraisal on smaller lines.
DSCR (debt service coverage ratio): Monthly rent divided by the full monthly obligation (principal, interest, taxes, insurance, and any HOA dues). It is the measure that DSCR loans use to qualify a rental.
HELOC or DSCR Cash-Out Refinance?
A HELOC leaves the first mortgage in place and underwrites the borrower. A DSCR cash-out refinance replaces the mortgage and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The right tool depends on the title, the income picture, and how much equity the borrower needs.
| Factor | Investment-Property HELOC | DSCR Cash-Out Refinance |
|---|---|---|
| Underwritten on | Borrower’s credit and DTI | Property’s rent vs. payment |
| Max leverage | 70% CLTV | Around 75% LTV |
| Credit floor | 700 | 620 in parts, most want ~660 |
| Title | Individual or revocable trust | LLC eligible per program terms |
| Size | $25,000-$500,000 line | Up to $3,000,000 on standard programs |
| First mortgage | Stays in place | Replaced |
The DSCR side has its own conditions. A cash-out typically wants about 6 months of seasoning and often around 6 months of reserves, though reserves vary by lender, leverage, loan size, and transaction type. A 1.00 coverage ratio is where select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.
Clearing 1.00 does not mean the rental produces positive cash flow. DSCR compares rent to the monthly obligation only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
Lendmire’s complete DSCR loans guide walks through how the ratio is calculated and which files fit.
Who Each Option Fits
A HELOC typically fits the borrower who holds title personally, has strong W-2 or documented income, carries a first mortgage worth keeping, and needs a moderate amount of equity. Examples are a down payment on the next rental or a rehab budget on the current one.
The stronger case for a DSCR cash-out appears in four situations:
- The property sits in an LLC.
- The borrower’s income does not support a 50% debt ratio.
- The investor needs more than a $500,000 line, or more leverage than 70%.
- The portfolio has grown past three lines or 15 financed properties.
Some files could go either way. A borrower with high income, personal title, and a low-balance first mortgage might choose the line for its flexibility. The same borrower with a first mortgage worth replacing might prefer the cash-out. The honest test is the exit plan. If the borrower cannot name how the balance gets repaid by the end of the draw period, neither product is the problem. The plan is.
Frequently Asked Questions
Can I get a HELOC on a rental I own through an LLC?
Not on this network’s equity lines. Title must be held by the individual borrower or a revocable living trust. A rental already deeded to an LLC would need a vesting change, or the owner can look at a DSCR cash-out refinance, which can work for entity-held rentals depending on program guidelines.
How much can I borrow against a single-family rental?
The ceiling is a combined loan-to-value limit, up to a $500,000 line, with a $25,000 minimum. Subtract the balance on any existing mortgage from that share of the home’s value to see the room. A borrower with a 720 score reaches the same limit as one with a 700.
Will the rental income qualify me?
Not the way it does on a DSCR loan. An equity line is underwritten on the borrower’s credit and debt-to-income, with a 50% maximum ratio. The lender tests the payment on the maximum draw. Rent supports the picture, but it does not qualify the file on its own.
Do I need an appraisal?
Usually not. Investment lines cap at $500,000, which keeps them in the automated-valuation lane, and full appraisals are required only above that size. A borrower can request a full appraisal, and a higher CLTV may call for a secondary valuation.
What happens when the draw period ends?
The line closes to new draws and repayment begins over 25 years, with principal and interest both due. Pricing floats the whole way and never converts to fixed. The monthly obligation rises noticeably, so test the rental’s cash flow against the repayment phase before drawing.
