The Quick Read: Many banks, credit unions, and wholesale lenders will open a home equity line on your primary residence and let you spend the draw on an investment, but very few will write a line secured by the rental itself. The lender usually cares about your equity, credit, and debts, not what you buy with the money.
- A line on your own home is the widely available route. A line on a rental is narrower and often has title and lien-position rules.
- Lendmire arranges lines through wholesale lenders. On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit profile and a $500,000 maximum line.
- On a primary residence, the network ceiling reaches 90% CLTV, but only at a 720-or-better credit profile.
- A line is underwritten on the borrower. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Which Banks Actually Offer This?
Big banks and large retail lenders mostly offer lines on a primary residence. Lines on a rental property come mostly from regional banks, credit unions, and portfolio lenders. NerdWallet says not all lenders offer a line on an investment property and that qualification is strict. Taxstra’s guide says many large national banks skip investment-property lines or restrict them heavily.
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 split matters because the product has two different collateral routes, and the search results blur them. One route borrows against the house you live in. The other borrows against the property you rent out.
No single institution is the right answer for every borrower. The lenders that write this product depend on the property, the equity, the credit profile, and how you hold title. Lendmire is a mortgage broker, not a lender. It works with a network of wholesale HELOC lenders and matches a file to the program that fits it. The wholesale placements below are limited to Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint, including Washington, D.C.
Key Terms Defined
HELOC: a home equity line of credit, a revolving line you borrow against your property’s equity.
Equity: what the property is worth minus what you owe on it.
CLTV (combined loan-to-value): all the loans on the property added together, divided by its value.
Draw period: the stretch when you can borrow from the line, often paying interest only.
Repayment period: the stretch after the draw ends, when you pay down principal and interest on a set schedule.
DTI (debt-to-income): your monthly debt payments compared with your monthly income.
DSCR: debt service coverage ratio, the property’s monthly rent divided by its monthly PITIA (principal, interest, taxes, insurance, and association dues).
Lien position: whether a loan sits first or second in line to be repaid from the property.
How a HELOC Works, Step by Step
A HELOC is an open-end line of credit. You borrow, repay, and borrow again up to a limit. According to the CFPB, the draw period is followed by a repayment period, and the home secures the debt. Missing payments can cost you the home.
Here is the sequence a borrower goes through.
1. Pick the collateral. This is your primary home or an existing rental.
2. Equity sets the ceiling. The limit is a percentage of appraised value minus what you owe. The CFPB’s HELOC booklet uses 75% as its example. Lenders set their own caps.
3. The lender reviews you. Credit, debts, and income come first. Rental collateral adds a property review.
4. Valuation. Many lines run on an automated valuation. Some files need a full appraisal.
5. Draw, then repay. Interest-only payments are common during the draw. The payment steps up when repayment begins, so plan for that day.
A HELOC behind an existing mortgage is a second mortgage. The CFPB notes that HELOC rates are usually adjustable, so the payment moves with the balance and the market.
How Underwriting Actually Treats the Line
Underwriting a line is about you, not the property you plan to buy. The lender asks whether your credit, your debts, and your equity support the new debt. The investment you fund with the draw is usually not part of the calculation, and a rental the draw buys does not count as collateral.
Across Lendmire’s wholesale network, the pattern looks like this:
- Debt-to-income: the maximum is 50%. For credit profiles from 600 to 679 the limit is 45%, and any ratio above 45% requires a credit profile of at least 680.
- How the payment is measured: the lender reviews your file on the interest-only payment calculated on the maximum draw, not the amount you plan to use.
- Credit: the program floor is 600, and a single-bureau score keyed to the primary wage earner is used. The report must be no more than 90 days old at closing.
- Valuation: lines of $500,000 or less ordinarily run on an automated valuation, though a higher CLTV may require a secondary valuation. Every line above $500,000 requires a full appraisal, and a borrower may request one in any case.
- Exposure: a borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible.
DSCR underwriting is the opposite. It compares the rent to the property’s PITIA and asks whether the property carries itself. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, management, and utilities sit outside the calculation. A line asks about your finances. A DSCR loan asks about the building.
Primary Home, Rental, or DSCR Cash-Out?
Three routes can put equity to work. They are different tools, so the table compares the structure of each.
| Factor | Line on your home | Line on a rental | DSCR cash-out |
|---|---|---|---|
| Collateral | Primary residence | The rental | The rental |
| Reviewed on | Your credit and DTI | Your credit and DTI | Property rent vs. PITIA |
| Availability | Widely offered | Narrower | Network-wide |
| Title | Individual or trust | Often individual | LLC possible* |
| Risk to your home | Yes | No | No |
*Subject to lender program eligibility.
The rest of this article leans on the first two columns, because those are the products the title asks about.
What the Network’s Lines Look Like
The following ranges come from the select wholesale lenders Lendmire works with. They are typical guidance, not commitments, and each file is reviewed individually.
Investment property lines. The ceiling is 70% CLTV, and the maximum line is $500,000. A 700 credit profile is a hard floor with no tier beneath it. A 720 score reaches the same 70% ceiling, so credit above 700 buys no extra leverage on a rental. Investment lines use a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats during both periods and never converts to fixed.
Primary-residence lines. The ceiling reaches 90% CLTV, but only for a 720-or-better credit profile. Two draw structures exist: a 3-year interest-only draw with a 17-year repayment, and the 5-year draw with a 25-year repayment, which this article calls the longer-runway program. On a primary residence, lines run from $25,000 to $750,000. A line above $500,000 is for primary residences only. It needs a 700 credit profile or better (720 on the longer-runway program), caps at 75% CLTV, and needs a full appraisal.
Both types. At least 75% of the line is drawn at closing on both programs, which differs from the flexible, draw-as-needed line many borrowers picture. After closing, the minimum subsequent draw is $1,000 under the longer-runway program.
Market comparison. NerdWallet reports that many lenders in the wider market cap investment-property lines below 70%. That is a market-wide observation, not a network figure. On this network, an investment line stops at 70% CLTV. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Where the General Rule Breaks
The rule is that a line is easy on your home and hard on a rental. These edge cases show where it bends.
Title in an LLC. Many investors hold rentals in an entity. On the network, the individual borrower or a revocable living trust must hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead.
Lien position. The network writes a standalone line in first or second lien position. Lenders in the market often want first lien on a rental. If your first mortgage is a DSCR loan, read its documents to confirm a second lien is allowed.
Property type. Single-family, 2-4 units, PUD, townhome, and condominium are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in several states.
Wording. Some lenders will not call it a HELOC on a rental. They may still consider a line of credit secured by investment property.
Line freezes. The CFPB’s HELOC booklet says a lender can reduce or freeze a line if the home’s value falls. If your plan depends on drawing again for the next deal, that risk is real.
Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years. A deed-in-lieu, pre-foreclosure, or short sale needs 4 years.
Using a Draw as a Down Payment
Picture an investor who owns a primary residence with strong equity and a 720 credit profile. She wants to buy a rental on a DSCR loan. Purchase leverage on most files lands at 75% to 80% LTV, so the down payment is 20% to 25%. Select programs reach 85% LTV with roughly a 700+ score.
She opens a line on her home and draws the down payment. Two checks now apply.
Check one: the line. Her credit, DTI, and equity must clear the line’s rules, and the line’s payment counts in her DTI.
Check two: the new loan. The DSCR lender looks at rent versus PITIA. A rent figure that clears 1.00 satisfies the coverage test, though 1.00 is where select programs start, not a universal standard. Stronger ratios open better terms and leverage. A separate select-lender path goes below 1.00, with leverage and terms adjusted.
Now stress-test it. The DSCR ratio ignores the line’s payment, but your bank account does not. Pricing on the line floats. If the rental sits vacant for a stretch, you owe the line’s payment from your own pocket. If your home’s value drops, the line can be frozen. The strongest files have both enough equity and enough rental coverage, plus cash that survives the stress case.
Does a DSCR Cash-Out Do the Job Better?
A line works best for short holds, such as a few months of rehab before refinancing. It is a poor fit for permanent leverage because the pricing floats and the payment steps up.
If you already own a rental with equity, a DSCR cash-out refinance can be the cleaner route. Cash-out tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A line caps investment CLTV at 70%, so the two products leave different amounts of equity available. Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around 6 months of PITIA.
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 those programs end to end.
Who Should Use a Line, and Who Should Skip It
A line tends to fit when:
- You own a primary home with real equity and a 720-or-better credit profile.
- The money is a short-term bridge, such as a down payment or a rehab.
- Your DTI has room after counting the line at its maximum draw.
- You can carry the payment from savings if the rental sits empty.
Skip it when:
- Your equity is thin or your home’s value is shaky.
- You need long-term fixed leverage. A line’s pricing floats and never converts to fixed.
- Your rental is held in an LLC and you do not want to retitle it.
- The funds would go to something speculative. The collateral is your home.
Questions to Ask Before You Apply
1. Do you offer a line secured by an investment property, or only by a primary residence?
2. What is the combined LTV ceiling for my occupancy type?
3. Does the property need to be titled to me personally?
4. Is the line first or second lien, and does my current mortgage allow it?
5. What valuation is used, and could a second one be required?
6. How much must be drawn at closing, and what does the line freeze policy say?
7. What happens to the payment when the draw period ends?
A broker that shops several wholesale lenders can run these questions against many programs at once. That is how a file gets matched to a program that fits, instead of being declined by a lender whose box it never fit.
Frequently Asked Questions
Can a HELOC on my home fund a rental down payment?
Yes, if the lender allows it, and many do not restrict how you spend the draw. The line’s payment counts in your DTI on any later loan, so a DSCR lender will see it. Keep the draw records as your paper trail.
Do big banks offer a line secured by a rental?
Rarely. Market sources say most large banks skip or restrict investment-property lines, and regional banks, credit unions, and portfolio lenders fill the gap. Lenders in Lendmire’s wholesale network offer it with a 70% CLTV ceiling and a 700 minimum credit profile.
Can an LLC hold the property that secures the line?
Not through the network’s lines. The individual borrower or a revocable living trust must hold title. If the property is in an LLC, the options are a vesting change or a DSCR cash-out.
How is a line different from a cash-out refinance?
A line is a separate second loan with a floating payment, and your first mortgage stays as it is. A cash-out refinance replaces the first mortgage with a new, larger loan. DSCR cash-out qualifies primarily on property-level rental income, subject to lender guidelines.
Will a line raise my DSCR?
No. DSCR compares rent to the PITIA on the loan being underwritten. A line does not change that, though it can fund a bigger down payment. A larger down payment lowers the monthly payment on the new loan, which can lift the ratio. It does not erase leverage caps, credit floors, reserve rules, or property eligibility.
