The Quick Read: A home equity line can fund a rental down payment, but two separate approvals decide whether it works. The line lender checks your credit and the equity in the collateral, and the purchase lender checks the property, the leverage, and where the cash came from. Across the wholesale network Lendmire works with, an investment-property line tops out at 70% combined loan-to-value (CLTV), meaning all loans against the property as a share of its value. So the real down payment question is how much equity the rental already holds.
- The line is sized from equity left over after your existing mortgage, not from a down payment of its own.
- Investment-property lines in the network require a 700 credit score and cap at $500,000 in total.
- The line must be open and funded before you go under contract on the next property.
- Borrowed down payment money is not accepted by every purchase program, so ask before you draw.
- Clearing a coverage ratio of 1.00 on the new rental does not mean the deal makes money. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
This is education, not a recommendation. Whether the play fits depends on your file.
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.
Key Terms Defined
HELOC (home equity line of credit): A revolving line secured by real estate. You borrow against it as needed during a draw period, then repay.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s monthly payment. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
PITIA: Principal, interest, taxes, insurance, and any association dues. It is the payment figure in the DSCR ratio.
DTI (debt-to-income ratio): Your monthly debt payments as a share of your monthly income. The line lender looks at it. A DSCR purchase lender mostly does not.
Seasoning: How long you have held a property or funds before a lender counts them.
Prepayment penalty: A fee some investor loans charge if you pay off early.
What “Down Payment Needs” Means Here
The phrase covers two different questions, and most people blur them. The first is how much equity the rental needs before a line exists. The second is how much cash the next purchase needs and whether line proceeds can supply it.
No federal rule sets a down payment for a line on a rental. The limits come from lender and investor policy. NerdWallet’s explainer says a line on an investment property is possible, but the lender pool is smaller, requirements are stricter, and availability is limited. Its companion page adds that you may borrow less than you could against a primary home.
A line on an owned rental has no down payment of its own. The equivalent is retained equity. The more you put down when you bought the rental, the more room sits under the ceiling today.
Step One: Size the Equity Cushion
The math is simple. Value times the maximum CLTV, minus every lien already on the property, equals the possible line.
Here is an illustration in percentages only, not a program quote. Say your first mortgage sits at 55% of the property’s value. Against a 70% CLTV ceiling, that leaves 15 points of value. If you bought the rental with a thin down payment and have not paid it down, you may have almost no room.
Market surveys report that some lenders allow up to 80% on investment-property lines, with many sitting below 70%, per NerdWallet. That is a market-wide statistic. The figure for an investment-property line in Lendmire’s network is 70% CLTV, with no higher tier.
Credit works a little differently than most people expect. On the network, 700 is a hard floor for investment lines. A 720 score reaches the same 70% ceiling as a 700. A higher score buys eligibility, not extra leverage.
Size also has a hard stop. Investment lines in the network cap at $500,000 in total. Because of that cap, most run on an automated valuation, and many close with no traditional appraisal. A borrower may still request a full appraisal.
Which Property Secures the Line?
You can put the line on an existing rental or on your own home. The two choices carry different tests and different risks.
| Factor | Line on the rental | Line on your home |
|---|---|---|
| Max CLTV in the network | 70% | Up to 90%, only at 720+ credit |
| Minimum credit | 700 | Lower floors, varies by program |
| Property at risk | The rental | Your residence |
| Who decides | Line lender | Line lender |
A home-secured line reaches higher leverage, but the collateral is where you live. A rental-secured line has a tighter ceiling, and a default puts the rental at risk. Neither choice is free of consequences.
How the Two Approvals Work
A line is a loan to you. The line lender looks at your credit, your DTI, and the equity in the collateral.
Experian lists DTI as a requirement and says lenders commonly want it below roughly 40% to 50%, depending on the lender. That page is older, so treat the range as a rough market picture. In the network, DTI tops out at 50%. It is qualified on the interest-only payment calculated on the maximum draw, not on whatever you plan to draw.
A DSCR purchase loan is a different test. It looks at the new property: its rent against its payment. Many select programs start at a 1.00 floor, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Either way, your personal DTI matters far less here.
So you clear two files. One judges you and the collateral. The other judges the property and the source of the cash.
Sequencing: The Line Comes First
The line generally needs to be open and funded before you sign a purchase contract. Lenders review bank statements, and a large deposit with no paper trail draws questions. Borrowed money that has sat in your account for a while is easier to document than money that landed last week.
One structural detail matters for planning. In the network, at least 75% of a line is drawn at closing. Pricing floats during the draw and the repayment period and never converts to fixed. So a line is a poor match if you wanted to leave most of it undrawn as a standby.
The steps look like this:
1. Check equity room on the rental or your home.
2. Confirm title, property type, and credit against the line’s rules.
3. Open the line and draw funds into your account.
4. Ask the purchase lender how it treats borrowed funds, before you rely on them.
5. Go under contract with documentation in hand.
6. Run the stacked payments, line plus new loan, against your actual cash flow.
Down Payment, Closing Costs, and Reserves Are Three Pots
A line draw is cash. The purchase lender decides which pots that cash may fill.
| Pot | What it covers | Borrowed funds? |
|---|---|---|
| Down payment | Equity in the new property | Depends on the program |
| Closing costs | Fees at closing | Usually less restricted |
| Reserves | Cash left after closing | Often must be your own |
Treat that table as a starting question list, not a rule set. Programs differ. Some want unborrowed funds in the down payment slot. Others accept a documented line draw.
On most DSCR purchases across the network, leverage lands at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select high-leverage programs reach 85% LTV on a purchase (15% down) with roughly a 700 or better score. Reserves commonly run around six months of PITIA. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about nine months. These are typical ranges, subject to lender guidelines.
If the line pays the whole down payment on a purchase at 75% LTV, you have financed close to 100% of the property across two loans. That is the part to stress-test. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Single-Family Eligibility Checks
Before applying, run this checklist against the property that will secure the line:
- Title. The individual borrower or a revocable living trust must hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. This is the sharpest difference from a DSCR loan, which can be made to an LLC, subject to lender program eligibility. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead.
- Property type. Single-family homes, 2-4 units, townhomes, planned unit developments, and condominiums, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial or mixed-use properties are not.
- Listing status. A property listed for sale, or listed within the past 60 days, is ineligible in several states.
- Exposure. A borrower is limited to three lines, and owning more than 15 financed properties makes you ineligible.
- Availability. These lines are offered in Lendmire’s 16 full-service states, narrower than the 41-market DSCR footprint, which includes Washington, D.C.
Credit history carries its own rules. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure-family events on investment files follow a seven-year path for a foreclosure and four years for a deed-in-lieu, pre-foreclosure, or short sale.
The Worked Example
Picture an investor with a rental that has a first mortgage at 55% of value and a credit score above 700. The line can reach 15 points of value, subject to the $500,000 cap and the lender’s valuation. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
She draws that line and plans to use it as the down payment on a second rental. The purchase lender runs the new property at 75% LTV. The new property’s DSCR is computed on the new loan’s PITIA only. Say rent clears that payment at roughly 1.2x. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
That 1.2x looks healthy. It leaves out the line payment on the first rental, and it leaves out repairs, vacancy, management, utilities, and capital expenses. DSCR compares rent to PITIA and nothing else. Clearing 1.00 is not positive cash flow.
Now stack the pieces. The line payment is interest-only during the draw period, and pricing floats. The investor’s real monthly picture is rent minus the new loan’s payment, minus the line payment, minus operating costs. A property at 1.2x can look thin once those are added.
Stress Tests Before You Draw
Run these before the draw, not after:
- Vacancy. Take rent to zero on the new property for a stretch. Can the line payment and the first mortgage still be paid from other income?
- A frozen line. An undrawn line is permission, not committed money, and lenders can freeze or reduce lines. Do not plan a purchase around money you have not drawn.
- Floating pricing. The line’s cost moves. Stress the payment above the opening level.
- The step-up. The investment line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. The payment jumps when amortization begins. Have an exit: refinance the new property, pay down the line, or sell.
- Prepayment penalties. Investor practitioners warn that a DSCR loan taken on right after buying can carry a prepayment penalty. That makes a quick refinance out of the stack more expensive.
When It Fits and When It Doesn’t
This is not advice. These are the patterns a broker sees most often.
It tends to fit when:
- The rental is held by you personally or in a revocable trust, with real equity under the 70% CLTV ceiling.
- Your credit sits at 700 or better and DTI is comfortably below the 50% maximum.
- Your need is a defined lump sum, since most of the line is drawn at closing anyway.
- The purchase lender has confirmed in advance that a documented draw counts toward the down payment.
It tends not to fit when:
- The rental is in an LLC, or was bought with a thin down payment and has little equity.
- You need a standby line you can leave mostly undrawn.
- The new deal only works at a coverage ratio near the floor, with no cushion for the added line payment.
- You are counting on the line to also cover reserves.
HELOC or DSCR Cash-Out?
When a rental sits in an LLC or has thin equity, a DSCR cash-out refinance is often the cleaner tool. It replaces the first mortgage instead of adding a second lien.
| Factor | Rental HELOC | DSCR cash-out refinance |
|---|---|---|
| What is tested | You: credit, DTI, equity | Property rent vs. payment |
| Title | Individual or revocable trust | LLC possible, per program |
| Leverage | 70% CLTV (investment line) | About 75% LTV on standard rentals |
| Size | $500,000 cap | Up to $3,000,000 on standard programs |
Cash-out on short-term-rental collateral tops out lower, at 70%, with about 12 months of hosting history expected. The seasoning expectation on standard cash-out files is about six months. For the full picture of how these loans work, see the complete DSCR loans guide.
Documentation Checklist
Gather these before you approach either lender:
- Mortgage statements on every financed property.
- Proof of title and vesting on the collateral.
- Your credit report. The network’s score is a single-bureau figure, and reports must be no more than 90 days old at closing.
- A paper trail for any line draw: the draw record and the bank deposit.
- For the purchase: a written answer on whether borrowed funds count toward the down payment.
Self-employed borrowers sometimes qualify on documented income under the applicable program, subject to lender guidelines. Bank-statement analysis for business accounts requires a 680 minimum, which sits below the 700 floor on investment lines. So income documentation is rarely the binding constraint on an investment line. Credit and equity are.
Not Legal or Tax Advice
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.

Frequently Asked Questions
Can I use a home equity line as my down payment on a rental?
Sometimes, depending on the purchase program. Some accept a documented line draw. Others want unborrowed funds. Ask the purchase lender before you draw, and have the line open and funded before you go under contract.
Can the line cover my entire down payment?
It may, but that leaves you near 100% financed across two loans. Reserves and closing costs are separate pots, and lenders often want reserves to be your own money. The line payment also hits your cash flow even though it sits outside the new property’s coverage ratio.
Can I open a line on the rental I’m about to buy?
No. You must own the property first, so it cannot fund its own down payment. The equity has to come from a property you already hold.
Can an LLC-owned rental get one?
Not in the network. Title must be held by an individual or a revocable living trust. A property deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead.
Does the line payment count in the new property’s coverage ratio?
Generally no. The ratio compares rent to the new property’s PITIA. The line payment still counts against your actual cash flow, so run both together.
