The Quick Read: A home equity line can supply the down payment on your next rental, but it is a separate loan from the purchase. The line is approved on your credit, debt load, and equity. The purchase loan, usually a DSCR loan, is approved mainly on the new property’s rent. The deciding question is whether the purchase lender accepts borrowed money as your down payment.
- The line and the purchase are two approvals. Each has its own rules, and neither erases the other’s.
- On Lendmire’s wholesale network, a line secured by an investment property tops out at 70% CLTV and $500,000, with a 700 minimum credit score, subject to lender guidelines.
- Many DSCR lenders accept documented line proceeds as a down payment. Some cap the borrowed share, and some do not accept borrowed funds at all.
- Borrowed money is commonly excluded from reserves, even when it is accepted for the down payment.
- A clean coverage ratio on the new rental does not mean the deal cash flows, because the line’s cost sits outside that ratio.
Two Loans, Two Approvals
A HELOC (home equity line of credit) is a revolving loan secured by property you already own. You draw cash and move it into your account. That cash then becomes your down payment on a separate purchase loan.
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 line is judged on you. A lender looks at your credit, your existing debts, and the equity in the property securing the line. It does not look at the rent on the property you plan to buy.
The purchase loan is judged mostly on the property. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. 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.
This split explains most of the confusion on the topic. The line only changes where your down payment comes from. It does not remove the down payment, the reserve requirement, or the credit rules on the purchase loan. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Lendmire is a mortgage broker, not a lender. It works with a network of wholesale HELOC lenders and a separate network of DSCR lenders. That matters for this topic, because the right fit depends on how the two sets of rules fit together for your file.
Key Terms Defined
HELOC: A revolving line of credit secured by real estate, with a draw period followed by a repayment period.
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the property’s value.
DSCR (debt service coverage ratio): The property’s monthly rent divided by its monthly PITIA. A ratio of 1.00 means rent equals the payment.
PITIA: Principal, interest, taxes, insurance, and any association dues on a property.
Source of funds: The paper trail that shows where your down payment cash came from.
Seasoning: How long money sits in your account before a lender treats it as your own.
Reserves: Cash left over after closing, usually counted in months of PITIA.
How Underwriting Treats the Line, Step by Step
Here is the sequence a typical file follows.
1. Check equity and CLTV on the property that will secure the line. Add the first mortgage and the proposed line, then divide by value. Your maximum line is the value times the CLTV cap, minus existing liens. Many junior-lien lenders count the full line, not just the drawn amount.
2. Qualify the line on you. Expect to document identity, income, insurance, and the mortgage on every financed property.
3. Ask the purchase lender about borrowed funds before you draw. Get the answer in writing, including any cap on the borrowed share.
4. Draw and move the money into your own account. The purchase lender will usually want the line’s closing documents and the draw confirmation. It will also want proof that your funds cover the down payment, closing costs, and reserves.
5. Let seasoning run its course, if the lender asks for it. Seasoning rules differ by lender. Some want funds to sit for a period, and others have no waiting rule. Disclose the source either way. Waiting is not a way to hide where the money came from.
6. Underwrite the purchase. The DSCR is the new property’s rent against its own PITIA. The line’s payment does not enter that ratio.
7. Plan the exit. Decide how the line gets repaid, whether from rent, a refinance, or savings.
The line closes on its own, before the purchase. It never closes together with the purchase.

What Investment Property HELOC Lenders Look For
The lender that fits you depends on your property type, credit profile, leverage need, and paperwork. No single name wins for every file. A broker that shops several wholesale lenders can match your scenario to the right program. Here is what those programs generally want on an investment-property line.
Experian notes that HELOC requirements on investment property are more stringent than on a primary home. That matches what the wholesale network shows.
| Item | Investment-property line |
|---|---|
| Max CLTV | 70% |
| Line size | $25,000 to $500,000 |
| Minimum credit | 700 |
| Max DTI | 50% |
| Draw structure | 5-year draw, 25-year repayment |
A few details sit behind that table.
- Credit above 700 buys eligibility, not leverage. A 720 profile reaches the same 70% CLTV as a 700 profile. Below 700, an investment line is not offered.
- DTI is tested on the interest-only payment at the maximum draw. That means the full line counts against your debt-to-income ratio, even if you plan to draw less.
- Most of the line is drawn at closing. Interest is running from day one. Pricing floats during the draw and repayment periods and never converts to fixed.
- Valuation is usually automated. Because an investment line caps at $500,000, it commonly closes with an automated valuation rather than a full appraisal. You may request a full appraisal.
- Title matters. The property must be held by you personally or by a revocable living trust. An LLC, corporation, partnership, or land trust cannot hold title on the line. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead.
- Property types are limited. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condos, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
- Portfolio caps apply. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the network’s higher-leverage program and $750,000 on its longer-runway program. A borrower with more than 15 financed properties is not eligible.
- Availability is narrower than the DSCR footprint. Lendmire’s DSCR investor programs cover 41 markets, including Washington, D.C. The investment HELOC is offered in 16 full-service states only.
These are program ranges, not promises. Every file is underwritten individually, subject to lender guidelines.
Which Property Should Secure the Line?
You have two choices. You can put the line on a rental, or you can put it on your own home. Each choice changes the risk and the ceiling.
| Factor | Line on a rental | Line on your primary home |
|---|---|---|
| CLTV ceiling | 70% | Higher, up to 90% at 720+ credit |
| Max line | $500,000 | Up to $750,000 |
| What is at risk | The rental | Your home |
Benzinga notes that a line on a rental uses the rental as collateral, and that missed payments put that rental at foreclosure risk. A line on your home shifts that risk to the roof over your head.
Many investors use a line on their home because the ceiling is higher and the rental stays clear of extra liens. That is a legitimate structure. It is also a real trade, because you are using your home to fund a business purchase.
A line on a rental also leaves that rental with a second lien. Many lenders refuse a third lien outright, so a rental with two existing loans is a hard fit.
How the Purchase Lender Treats Borrowed Funds
This is where the deal succeeds or fails. Across the DSCR lenders in the network, programs split into three camps.
- Some accept borrowed funds fully, as long as the source is documented.
- Some cap the borrowed share of the down payment.
- Some want part of the down payment from your own seasoned cash.
A fully borrowed down payment can fail at certain lenders on that point alone. Other programs accept it. The only way to know is to ask before you draw.
For contrast, agency loans work differently. Fannie Mae’s selling guide treats borrowed funds secured by an asset as an acceptable source for its own conventional loans. DSCR loans are not agency products, so that rule does not govern them.
Down payment, closing costs, and reserves are three separate pots. Borrowed money is often accepted for the first two. It is commonly excluded from reserves. A line does not shrink that requirement.
A purchase lender typically wants this document set:
- The line agreement and closing documents.
- Draw confirmation showing the amount and date.
- Statements showing the funds landing in your account.
- Evidence that the funds cover the down payment, closing costs, and reserves.
Keep line proceeds separate from personal spending so the money stays traceable.
What the Purchase Loan Still Requires
A larger down payment, borrowed or not, shrinks the new loan and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Across the network, purchase leverage on a DSCR loan most often lands at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV with roughly a 700-plus score. Credit minimums vary by DSCR program, so confirm the floor for your scenario before you draw on the line. Note that the HELOC itself on an investment property requires at least a 700 score, and a 700-plus profile also opens the strongest DSCR leverage tiers.
On coverage, 1.00 is where many 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.
A larger down payment can lift the ratio, but the ratio is not a cash-flow measure. It compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it.
A Worked Example
The numbers below are modeled assumptions, not market data.
Say you own a primary home with ample equity and a 740 credit profile. You want a duplex, and the purchase program asks for 25% down, which is a 75% LTV purchase. The rent clears roughly 1.2x on the new loan. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
You open a line against your home. A primary-residence line can reach up to 90% CLTV at a 720-or-better profile, so equity is not the constraint. You draw enough to cover the down payment, closing costs, and reserves, if the purchase lender allows borrowed reserves. Many do not.
The purchase underwrites at about 1.2x. The line’s payment is not in that ratio. Your real cash flow is another matter.
Now stress it. The line’s cost floats, and it can step up when the draw period ends. At least 75% of the line is drawn at closing, so interest is running from day one. The duplex’s 1.2x never moves, but your out-of-pocket position does. Rent covers the new loan, and nothing covers the line.
That is why the exit plan matters. Plan to carry the line until the rental stabilizes or you refinance. If the deal only works because the down payment is borrowed, re-examine the deal.
Where the Rule Breaks
Here are the named edge cases.
- Reserves. Borrowed funds may cover the down payment and still be refused as reserves.
- LLC-held rentals. The line cannot be secured by an LLC-titled property. You would use a personally titled home, or a different structure, subject to program terms.
- Third-lien position. Many lenders will not write a third lien.
- DTI-based loans. On a conventional loan, the new line’s payment lands in your debts and can break your DTI. DSCR avoids that ratio, but not the real cost.
- A listed property. In some states, a property listed for sale, or listed within the past 60 days, is ineligible for the line.
- Credit events. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, a foreclosure follows a seven-year path, and a short sale or deed in lieu follows a four-year path.
- Portfolio size. More than 15 financed properties makes you ineligible for the line.
- Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered, either on the line or on the DSCR purchase.
HELOC or Alternative?
| If you… | Consider |
|---|---|
| Have equity in your home and cash-flow cushion | Line on the primary home |
| Hold a seasoned rental with real equity | DSCR cash-out refinance |
| Own the rental in an LLC | DSCR cash-out refinance |
| Have a thin margin on the new deal | Saved cash or a smaller purchase |
A DSCR cash-out refinance on a standard rental tops out around 75% LTV across most of the network. About six months of seasoning is the common expectation. It replaces your existing loan, so it is a bigger move than adding a line. It does keep everything in one structure and avoids the borrowed-funds question entirely. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Frequently Asked Questions
Can I use a HELOC as the down payment on a rental?
Often yes, but it depends on the purchase lender. Many DSCR lenders in the network accept documented line proceeds. Some cap the borrowed share, and some want part of the down payment from your own cash. Ask in writing before you draw.
Does the HELOC payment hurt my DSCR?
Generally no. The DSCR compares the new property’s rent to its own PITIA, and the line’s payment is not part of that ratio. It can still hurt a DTI-based loan, and it still comes out of your pocket.
Can an LLC hold the property that secures the line?
No. On the network’s programs, title must sit with you or a revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead.
Will borrowed money count toward my reserves?
Commonly not. Many purchase lenders accept borrowed funds for the down payment and closing costs but exclude them from reserves. Reserve rules vary by lender, leverage, and loan size.
Does a higher credit score get me a higher CLTV on an investment line?
No. On the network’s investment line, 720 reaches the same 70% CLTV as 700. Credit above 700 adds eligibility, not leverage.
