The Quick Read: A home equity line of credit (HELOC) does not buy a rental by itself; it produces cash that usually covers the down payment while a separate purchase loan closes the acquisition, so the right bank depends on whether the line sits on your primary home or an existing rental, and fewer lenders write investment-collateral lines than owner-occupied ones.
- Few large retail banks write lines on rental collateral. Community banks, credit unions and specialty lenders fill most of the gap.
- On Lendmire’s wholesale network, an investment-property line tops out at 70% combined loan-to-value (CLTV), requires a 700 credit score, and caps at $500,000.
- A line on your primary home is the more common route, but it puts a lien on the house you live in.
- The purchase lender decides whether borrowed down-payment money is acceptable, and that rule changes by program. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
This article walks through how these lines work, how the purchase loan treats them, and where the usual rules break. Lendmire is a mortgage broker, not a lender, so it does not rank or recommend banks. It shows you what these lenders look for and how a broker matches a file to a program.
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.
Which Path Do People Mean by a HELOC to Buy a Rental?
There are two products behind this search. One is a HELOC on your own home, and the other is a HELOC on a rental you already own. Both give you a revolving pool of cash. Neither one closes your purchase.
Path A: the line sits on your primary home. This is the common approach. You draw cash against your own equity and use it as the down payment on the next rental. The risk is plain: the house you live in secures the debt.
Path B: the line sits on a rental you already own. Fewer lenders offer this, and the requirements run stricter. The lender studies the rental’s finances along with your credit. If the property is thinly covered by its own rent, a new payment on top can strain it.
Experian says a HELOC on a rental is usually harder to qualify for than one on a primary home. NerdWallet adds that not all lenders offer the product and that requirements are strict. Expect a narrower field than you would find for a standard home equity line.
Which Banks Offer an Investment Property HELOC?
Availability is thin, and it shifts by lender, location and property use. Some lenders restrict these lines by location and by whether the home is rented year-round. Bankrate reports that there simply aren’t as many lenders offering HELOCs on investment properties.
This article names no institutions, because offerings change often and any list goes stale. Sort lenders by type instead.
| Lender type | Typical stance on rental collateral | How to approach |
|---|---|---|
| Large national banks | Few offer it; tighter standards | Ask if rental collateral is allowed at all |
| Regional and community banks | More flexible, often case by case | Start with your existing relationship |
| Credit unions | Sometimes willing, membership required | Ask about property use and location limits |
| Specialty and investor-focused lenders | Built for rental owners | Compare terms and eligibility rules |
| Mortgage broker | Shops several wholesale lenders | Match your scenario to a program |
A broker earns its place in the last row. A bank can only offer its own product. A broker places the file with the lender whose program fits the property, the credit profile and the leverage you need. The lender that writes a given file depends on the situation, so the best program for your situation is a matching question and not a ranking question.
Lendmire works with a network of select wholesale HELOC lenders. This HELOC product is available in 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 the 41-market DSCR footprint, which covers 40 states plus Washington, D.C.
How Underwriting Treats the Line, Step by Step
Put the line in place before you make an offer, so the funds are ready when the seller accepts. The sequence below shows what each lender looks at.
1. Pick the collateral. A primary-home line is underwritten like an owner-occupied loan. A rental line is underwritten on both your credit and the property’s finances, as Bankrate describes.
2. Measure the equity. Subtract the mortgage balance from the property’s market value. Then add the proposed line to see the combined balance against value.
3. Gather documents. Benzinga lists proof of income, tax returns, rental agreements and proof of insurance. NerdWallet notes that some lenders ask for multiple appraisals to confirm value.
4. Open the line. Approval and closing come first, ahead of your purchase offer.
5. Draw and document the draw. Keep the line agreement, the draw statement and the deposit record. The purchase lender will want to trace where the down payment came from.
6. Underwrite the purchase. A DSCR loan reads the new property’s rent against its own payment. It does not run a personal debt-to-income test.
7. Repay or restructure. Once the rental is stable, you pay the line down, or you roll the balance into a different structure.
The purchase underwrite in step six is where the plan succeeds or stalls, and the edge cases in the section on where the general rule breaks cover the details.
What These Lines Look Like on Lendmire’s Wholesale Network
Market surveys report that investment-property HELOCs cap near 80% of value (Experian). On Lendmire’s network, an investment line caps at 70% CLTV. CLTV is your first mortgage plus the new line, divided by the property’s value.
Typical parameters for an investment-property line, subject to lender guidelines and full file review:
- Credit: a 700 minimum. Both the 720 and 700 tiers reach the same 70% CLTV, so a higher score adds eligibility and not extra leverage.
- Line size: an investment line tops out at $500,000. Lines above that size are limited to primary residences.
- Structure: a standalone line in first or second lien position, with a 5-year draw period and a 25-year repayment period. At least 75% of the line is drawn at closing.
- Pricing behavior: pricing floats through both the draw and repayment periods and never converts to fixed.
- Debt-to-income: 50% maximum, qualified on the interest-only payment calculated on the maximum draw.
- Valuation: because the line caps at $500,000, an investment line ordinarily uses an automated valuation. A traditional appraisal is not typically required, though a borrower can request one.
- Title: the borrower must hold title as an individual or in a revocable living trust. An LLC, corporation, partnership, or irrevocable, blind or land trust cannot hold title. This is the sharpest difference from a DSCR loan, so a rental already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead.
- Property types: single-family, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agriculturally zoned properties are not offered.
- Exposure: a borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.
Primary Home or Rental: Which Collateral Fits?
The primary-home line usually offers more room. On a primary residence the ceiling reaches 90% CLTV, and only at a 720 or better credit profile. An investment-property line stops at 70%.
| Factor | Line on primary home | Line on a rental |
|---|---|---|
| Maximum CLTV | Up to 90%, only at 720+ | 70% |
| Credit floor | Varies by program | 700 |
| Line size | Above $500,000 allowed | $500,000 cap |
| Lien at risk | The house you live in | The rental |
The tradeoff is risk, not just leverage. A line on your home puts your residence behind a purchase you hope will cash flow. A line on a rental keeps the risk inside the investment, but the new payment competes with that property’s own rent. If that rental sits vacant, you owe on the line and have no income to cover it.
Think of the choice as a question about where you are willing to be exposed. Investors with plenty of home equity and a stable income often prefer the primary-home route. Investors who want to keep their residence clear of the deal may use the rental, accepting lower leverage.
Where the General Rule Breaks
These are the edge cases that change the outcome.
Borrowed funds and reserves. Many DSCR programs accept documented HELOC money for the down payment or closing costs. They often exclude it from reserves. Reserves are the cash left after closing, commonly around 6 months of PITIA (principal, interest, taxes, insurance and association dues), though the number varies by lender, leverage, loan size and transaction type.
Borrowed share limits. Some programs cap how much of the down payment can be borrowed. Others want part of it unborrowed. This rule is program-dependent, and it is the one to confirm before you open a line.
Gift funds and unsecured borrowing. Gift funds on an investment purchase are often restricted, so ask the DSCR lender before you count on them. A personal loan or credit card advance is also not the same as a HELOC, and lenders generally do not accept it for the down payment.
The HELOC payment on a DSCR file. A DSCR loan compares rent to PITIA and does not formally compute debt-to-income. Some lenders still look at the line’s payment in the overall picture. A conventional purchase is different: the new line’s payment lands directly in your debts and can break the ratio.
An existing rental as collateral. The line’s payment competes for the same rent. Add it to the rental’s own payment and the property’s coverage can slip on a refinance later.
Seasoning of funds. Lenders want to trace the money. Cash that sits in a visible account with a paper trail from the line is easier to document than cash that moves through several accounts.
Investor-focused equity lenders. Some specialty lenders qualify second mortgages and HELOCs on rental income instead of tax returns. These are a narrow niche, and terms vary by program.
A Worked Example in Percentages
Say you own a rental with a first mortgage at 50% of its value, and you want a line on it. The investment ceiling is 70% CLTV, so the line could reach about 20% of the property’s value, subject to the $500,000 cap and a 700 credit score. That is the most the collateral allows. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Now picture the purchase. A standard DSCR purchase typically runs 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV, or 15% down, with roughly a 700+ score. Closing costs come on top of that.
Whether the line covers the down payment depends on the size of the new purchase relative to the equity you are borrowing against. A small property may fit. A larger one may need a primary-home line or a mix of cash and line.
Then the new rental has to pass its own test. Coverage of 1.00 is where select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted. A DSCR of 1.00 is not positive cash flow. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation.
The strongest files pass two tests: enough equity to fund the down payment, and enough rental coverage to carry the new loan. A larger down payment can lift the DSCR, but it does not erase credit floors, reserve rules or property eligibility.
Questions to Ask a Bank Before You Apply
Each application can mean a hard credit pull. Ask these first to avoid wasted inquiries.
- Do you write lines on rental collateral in my state, and for my property type?
- Does the line require the home to be rented year-round, or does it allow short-term use?
- Will you accept a rental held in an LLC, or do you require individual or trust title?
- What is the maximum combined loan-to-value for an investment property?
- Will the valuation be automated, or will you need an appraisal?
- Can you freeze or reduce the line after it opens?
- Does the pricing float, and is there any option to convert to fixed?
A broker can run this screen across several lenders at once. That is the practical advantage of a network over a single bank.
What Can Go Wrong
A frozen or reduced line. A lender can limit access to a line under its agreement. If that happens between your offer and your closing, the down payment can disappear. Draw the cash and document it before you commit to the purchase.
Floating pricing. The line’s cost moves, and it never converts to fixed on these programs. Bankrate notes that pricing and fees on investment-property lines are typically higher than on primary-home lines.
Stacked debt. You now owe on the line and on the new mortgage. Benzinga points to foreclosure risk on the collateral and the burden of extra debt.
Vacancy. The line payment arrives whether or not the rental has a tenant. Keep cash outside the line for slow months.
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.
Alternatives to Consider
A line is one way to fund the down payment. Compare it with the other tools.
| Option | How it works | Fits when |
|---|---|---|
| HELOC on primary home | Draw cash, use as down payment | You have strong home equity |
| HELOC on a rental | Draw against existing rental | You want the risk inside the investment |
| Cash-out refinance on a rental | Replace the loan, take equity | You can accept a new first mortgage |
| Larger savings-funded down payment | No borrowed funds | You want the simplest file |
A cash-out refinance on a standard rental tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. On short-term-rental collateral the cash-out ceiling is 70%. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
For the purchase itself, a DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Credit requirements and leverage tiers differ by program, so confirm them with your loan officer. The complete DSCR loans guide covers the full structure. DSCR on manufactured homes, log homes and barndominiums is not offered.
Key Terms Defined
HELOC: a revolving line of credit secured by property equity, with a draw period followed by repayment.
CLTV (combined loan-to-value): your first mortgage plus the new line, divided by the property’s value.
DSCR (debt service coverage ratio): monthly rent divided by the monthly payment on the property.
PITIA: principal, interest, taxes, insurance and association dues, the full monthly obligation.
Reserves: cash you hold after closing, often counted in months of PITIA.
Seasoning: the time funds or ownership must be in place before a lender accepts them.
Lien position: whether a loan sits first or second in line for repayment.
Frequently Asked Questions
Can you use a HELOC to buy a rental property?
Yes, in most cases you use it for the down payment and closing costs, not the whole price. A separate purchase loan, often a DSCR loan, covers the rest. The purchase lender decides whether borrowed funds are acceptable, so confirm that before you draw.
Do big banks offer HELOCs on investment properties?
Few do. Bankrate reports that there are not many lenders offering them, and NerdWallet says the product is not offered by all lenders. Regional banks, credit unions and specialty lenders are more common sources, and a broker can screen several at once.
What credit score do I need for an investment-property line?
On Lendmire’s wholesale network, 700 is the minimum, and it is a hard floor. A 720 profile reaches the same 70% CLTV, so a higher score adds eligibility and not leverage. Each lender sets its own guidelines.
Will a HELOC hurt my DSCR on the new rental?
On most DSCR files, the purchase loan reads only the new property’s rent against its own payment. Some lenders still review the line’s payment in the overall picture. A conventional purchase, by contrast, counts the payment in your debts.
Can I hold the property in an LLC and still get the line?
No. An investment line requires title in your own name or a revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance can pull equity instead.
