The Quick Read: A HELOC on one rental can fund the down payment, closing costs, or reserves on the next purchase, but it works as two separate loans. The line lender approves the borrower and the equity in the first rental, while the purchase lender approves the new property and its rent against its own payment. Neither approval guarantees the other, and each lender reads a different file.
- On an investment-property line, the network ceiling is 70% combined loan-to-value (CLTV), with a line of up to $500,000 and a 700 minimum credit score, subject to lender guidelines.
- The rental must be titled to an individual or a revocable living trust. An LLC cannot hold title on the line.
- A DSCR purchase loan measures rent against the new property’s payment only. Clearing 1.00 does not mean the deal cash-flows.
- Ask the purchase lender whether borrowed down-payment funds are accepted before you draw anything.
How the Two Loans Fit Together
The sequence matters more than the product. Investors who treat the line and the purchase loan as one approval usually find the gap late, when it costs the most to fix.
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.
1. Size the equity. The line lender takes the first mortgage plus the new line and divides by the property’s value. That is the combined loan-to-value. The line can only fill the space between the existing balance and the lender’s cap.
2. Apply for the line. The line lender reviews credit, debt load, and the equity in rental #1. It is approving you, not the property you plan to buy.
3. Draw the funds. On the network’s investment lines, at least 75% of the line is drawn at closing. That means most of the money moves at once, and interest-only payments begin on what you drew.
4. Document the source. The purchase lender will want to see where the down payment came from. A line draw leaves a clear paper trail, and some programs treat borrowed funds differently than savings.
5. Close the purchase loan. It carries its own down payment, reserve, and coverage tests. DSCR is monthly rent divided by the full monthly payment: principal, interest, taxes, insurance, and any HOA dues.
6. Carry both obligations. The line payment sits outside the new property’s DSCR, but it still comes out of the investor’s pocket every month.
Experian notes that a HELOC can supply the down payment on another rental without draining savings or refinancing the current loan. It also notes that fewer lenders offer lines on rentals than on primary homes. Both points match what shows up on files.
Which Property Supplies the Equity?
Many investors have two choices: a line on the rental or a line on their own home. The right choice depends on risk tolerance and on how much equity each property has.
| Factor | Line on the rental | Line on your home |
|---|---|---|
| Lender availability | Narrower field | Wider field |
| What is at risk | The rental | Your residence |
| Network CLTV ceiling | 70% on an investment property | Higher tiers, tied to credit |
| Entity ownership | Individual or revocable trust only | Individual or revocable trust only |
A line on a primary residence carries a different kind of risk. Nasdaq flags foreclosure exposure on the home when a line funds a down payment. A rental-secured line keeps that risk on the investment side, but a heavily mortgaged rental may leave no usable room at all.
Run the equity math in percentages. At the 70% CLTV investment ceiling, a rental carrying a first mortgage at 50% of its value leaves room for a line worth up to 20% of that value. A rental already financed at 65% leaves almost nothing. The $500,000 line ceiling applies on top of that, so a high-value rental with a small mortgage is capped by dollars before it is capped by percentage.
What the Line Lender Looks At
Across the network, an investment-property line runs on a short list of tests. All of it is subject to lender guidelines and full file review.
- Credit. Investment lines require a minimum 700 score. The 720 tier and the 700 tier both reach 70% CLTV, so a higher score buys eligibility, not extra leverage.
- Line size. Lines run from $25,000 up to $500,000 on investment property. There is no larger investment tier.
- Debt-to-income. The ceiling is 50%, and the qualifying payment is calculated on the interest-only payment at the maximum draw. A file can look fine at a partial draw and still fail at the full line.
- Valuation. Because investment lines cap at $500,000, they usually run on an automated valuation with no traditional appraisal. A borrower can still request a full appraisal.
- Structure. The line has a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats during both phases and never converts to fixed.
- Exposure. A borrower is limited to three lines, and a borrower with more than 15 financed properties is not eligible.
- Derogatory credit. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history on investment files follows a 7-year path, and a deed-in-lieu, pre-foreclosure, or short sale follows a 4-year path.
- Property type. Single-family, 2-4 units, PUD, townhome, and condominium (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
- Availability. Lines are offered only in the 16 states where Lendmire provides full-service lending. That is narrower than its 41-market DSCR footprint.
A property that is listed for sale, or was listed within the past 60 days, is ineligible in several states. Check this before you apply on a rental you are thinking of selling.
Title and Vesting: The Common Wall
A common reason a file stalls is how the first rental is titled. The line requires fee simple or leasehold title held by the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
That is the sharpest structural difference from a DSCR loan. A DSCR cash-out refinance can be written to an LLC borrower, subject to lender program eligibility. A rental already deeded to an LLC needs one of two fixes. The owner can change the vesting, which has its own transfer and insurance steps. Or the investor can skip the line and take a DSCR cash-out refinance instead.
Decide this before you spend time on a line application. Many investors learn it only after the credit pull.
The Purchase Side of the File
The purchase lender cares about the new property. Most DSCR purchase files in the network land at 75%-80% LTV on a purchase, which means 20%-25% down. Select high-leverage programs reach 85% LTV on a purchase (15% down) with roughly a 700+ score. Loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Coverage is where the property earns its place. A 1.00 ratio is where select programs start. It is a floor for specific programs, not a standard. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Credit and reserves matter too. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around 6 months of PITIA, and larger loans step up from there.
The borrowed-funds question is where programs differ. Some lenders accept a line draw as down-payment money. Others dislike it, and some will count the line payment against the borrower. Ask for the answer in writing before the draw, not after. Clean reserves documentation helps either way, because the line draw can fund the down payment while savings still cover reserves.
The line also cuts the other way. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
For the full set of program mechanics, see Lendmire’s complete DSCR loans guide.
Stress Test: What Happens When a Tenant Leaves?
A DSCR ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. The line payment sits outside it too.
Run the numbers on a modeled case. Assume rental #2 is a two-unit property with equal rents, and its coverage ratio is about 1.25x on its own loan. This is a modeled assumption, not a market figure.
| Item | Both units rented | One unit vacant |
|---|---|---|
| Rent against the new loan | About 1.25x | About 0.63x |
| Line payment on rental #1 | Still due | Still due |
| Cushion for repairs and management | The 0.25 above 1.00 | Gone |
The total picture has three obligations: the first mortgage on rental #1, the line, and the new mortgage. All three need coverage. A ratio that clears 1.00 on paper can still leave the investor funding the line payment from other income.
The break-even question is simple. Does the new deal’s net income justify the cost of borrowed down-payment money? A property that only covers its own loan does not answer that. A property that covers its own loan plus the line payment, with room for vacancy, does.
Here the line can also help. Using a line means keeping the low-payment first mortgage on rental #1 instead of refinancing it, which is why investors choose it. The tradeoff is that the new purchase is financed at close to 100% of its price when the line funds the down payment.
HELOC or Cash-Out Refinance?
Both tools move equity into cash. They suit different files.
| Situation | Better fit |
|---|---|
| Rental is held in an LLC | DSCR cash-out refinance, subject to program terms |
| Need is small and repaid soon | Line on rental #1 |
| Need is large or longer-term | Cash-out refinance |
| Want a fixed payment structure | Cash-out refinance, since the line’s pricing floats |
| Rental #1’s first mortgage is worth keeping | Line, so the first mortgage stays in place |
On a cash-out refinance of a standard rental, the network tops out around 75% LTV, and about 6 months of seasoning is the common expectation. Short-term-rental collateral is lower, at 70% on a cash-out. The investment-property line tops out at 70% CLTV, so a cash-out refinance can pull more equity on the same property when the title and the first mortgage allow it. Rent can also cap proceeds on a cash-out before equity does. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
A line suits quick payback, such as a flip or a BRRRR deal where a refinance repays it. A longer hold usually fits a cash-out refinance better. Investors who want the details on a second line can read Lendmire’s piece Can a Self-Employed Landlord Open a Rental HELOC to Buy Another Property?.
Where the General Rule Breaks
Payment shock. The CFPB explains that a line has a draw period and a repayment period, and that payments are often significantly higher in repayment. Its pricing is also usually variable. On the network’s investment lines, the interest-only draw lasts 5 years, then the 25-year amortizing period begins. Model the investment on the higher payment, not the interest-only one.
Interest on drawn money only. The FTC confirms that you pay interest on what you draw, not the full limit. It also notes that the advertised cost of a line reflects interest only and leaves out points and other charges. Because most of a network investment line is drawn at closing, this benefit is smaller than it first appears.
Draw-then-freeze. An undrawn balance is permission, not committed money. A lender can reduce or freeze a line. The practical lesson is to plan the purchase around what the line funds at closing, not around future draws. After closing, the minimum subsequent draw on a primary-residence line is $1,000, with Texas at $4,000.
Ineligible properties. Manufactured homes, log homes, and barndominiums are not offered on DSCR loans in the network, and they are not eligible for the line either. A rental in one of those categories needs another path.
Short-term rentals. Some lenders limit or exclude short-term-rental collateral on lines. On the DSCR side, short-term-rental purchase leverage tops out at 75% LTV, and refinance runs around 70%. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Tax. 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.
Key Terms Defined
Combined loan-to-value (CLTV): the first mortgage plus the new line, divided by the property’s value.
Draw period: the window when you can borrow against the line, followed by the repayment period when borrowing stops.
DSCR: monthly rent divided by the full monthly payment on the property.
Seasoning: how long a loan, deed, or deposit has existed before a lender will count it.
Vesting: the name or entity that holds legal title to a property.
Source of funds: the documented origin of money used for a down payment or reserves.
Is This the Right Move? A Pre-Flight Checklist
Run through these before applying.
- Rental #1 is titled to you or your revocable trust, not an LLC.
- The equity left after the first mortgage supports the line you need at 70% CLTV.
- Your credit is at least 700, and your debt-to-income works at the full line.
- The purchase lender has confirmed that borrowed down-payment funds are accepted.
- Rental #2 covers its own loan with room left over for the line payment and vacancy.
- Reserves are documented separately from the draw.
- You can carry all three payments if one tenant leaves.
If two or more of these fail, a cash-out refinance, a smaller line, or a larger down payment from savings may serve the deal better.

Frequently Asked Questions
Can the line cover the entire purchase?
Rarely. An investment line caps at $500,000, and the purchase lender still expects a down payment, typically 20%-25% on most files. The line usually funds the down payment, closing costs, and part of the reserves, while the DSCR purchase loan covers the rest.
Does the line payment affect the DSCR on the new property?
No, because DSCR reads the new property’s rent against its own payment. The line payment still reduces what the investor keeps, and the line lender counts the line in its own debt-to-income test. Some purchase lenders also review the borrower’s other debts, so confirm how the lender treats it.
Can an LLC-owned rental get this kind of line?
Not as titled. The line requires individual or revocable living trust title, so an LLC-held rental needs a vesting change or a DSCR cash-out refinance instead.
Should I choose a line or a cash-out refinance?
It depends on the size of the need and how long you will carry it. A line suits a smaller, shorter-term need and keeps the first mortgage in place. A cash-out refinance suits larger or longer-term needs and can pull more equity, up to about 75% LTV on a standard rental. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What happens if a tenant leaves?
All three obligations keep coming due: the first mortgage on rental #1, the line, and the new loan. A property that clears 1.00 on paper can still run short once rent stops, because vacancy, repairs, and management sit outside the ratio.
