The Quick Read: You can usually borrow up to 70% combined loan-to-value on the investment property securing the line, minus what you still owe on the first mortgage, with a $500,000 ceiling and a 700 credit score floor. The DSCR purchase lender then decides separately how much of that cash counts as your down payment.
- The line is sized by equity: property value times 70%, less all existing liens.
- No DSCR purchase is zero down. The line changes only where the down payment cash comes from.
- Borrowed cash is often excluded from reserves, so plan reserves separately.
What “Behind a DSCR Loan” Actually Means
Investors use the phrase two ways, and the answer changes with each. The first is a line on a rental you already own, where a DSCR loan sits in first position and the HELOC goes second. The second is a line on the property you are about to buy, which would have to sit behind the new DSCR loan in lien order.
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.
A line drawn against equity in your current property is a separate lien with a separate approval. It closes and is drawn before you make an offer, not alongside the purchase. Lendmire is a mortgage broker that arranges these loans through select wholesale lenders in a 41-market network, including Washington, D.C. Across that network the two loans are two different underwriting files with two different tests.
The second meaning, a line on the new property, is rarely practical. The lender on the purchase wants to see the down payment sourced and seasoned before closing, and a line that does not exist yet cannot supply cash on day one. That is why the rest of this article assumes the line sits on a property you already own.
Key Terms Defined
Bank statement HELOC: a home equity line of credit where the lender reviews documented deposits instead of tax returns. It still checks credit, equity, debt load, title and property type.
CLTV (combined loan-to-value): all loans secured by the property, added together, divided by the property’s value.
Second lien: a loan that sits behind the first mortgage and gets paid after it if the property is sold or foreclosed.
DSCR (debt service coverage ratio): monthly rent divided by the property’s full monthly housing obligation, meaning principal, interest, taxes, insurance and any association dues.
Draw period: the stretch of the line during which you can borrow and pay interest only, before the balance begins amortizing.
How Big Can the Line Be?
Three limits apply, and the smallest one wins. Walk through them in order.
Limit one is the equity formula. Multiply the securing property’s value by the CLTV cap, then subtract every lien already on it. On an investment property the cap on this network is 70% CLTV. Picture a rental with a first mortgage at 50% of its value. The line could reach about 20% of value. If that first mortgage sits at 65% of value, only about 5% of value remains. At 70% of value or more, there is no room at all.
Limit two is the dollar ceiling. An investment line runs from $25,000 to $500,000. A very valuable, lightly leveraged property hits the ceiling before it hits the equity formula. A modest property with a large first mortgage may not clear the minimum.
Limit three is credit and debt load. The floor on an investment line is 700, and it is a hard floor with no tier beneath it. Debt-to-income can run to 50% at most, and the lender tests it using the interest-only payment on the maximum draw, not on what you plan to take. A big line you do not intend to use can still squeeze that ratio.
Because the ceiling is $500,000, an investment line sits in the automated valuation lane. A traditional appraisal is commonly not required, though a borrower can request one. Full appraisals begin only above $500,000, and lines above that size are limited to primary residences.
Two Approvals, Two Tests
| Factor | Bank statement HELOC | DSCR purchase loan |
|---|---|---|
| Property tested | The one securing the line | The one being bought |
| Core question | Is there enough equity and credit? | Does rent cover the payment? |
| Income read | Documented deposits | Rent on the new property |
| Title | Individual or revocable trust | Entity allowed, per program |
| Down payment | Supplies cash | Decides how much counts |
The line lender never asks whether the new rental will cash flow. The purchase lender never asks how much equity your current property has left. Each loan has to pass on its own. The strongest plans clear both tests: enough equity and enough rental coverage.
Worked Math: From Equity to Down Payment
Take a purchase that needs 25% down, which sits in the usual 75%-80% leverage range for most DSCR purchase programs. Assume the line supplies 20% of your current property’s value. The line covers the entire down payment only when the new purchase price is about 80% of the current property’s value or less. Divide 20 by 25 and you get 0.80.
Move the target price up and the gap appears. If the new property costs about the same as the one securing the line, the line covers 20% of the new price, and you need another 5% from cash on hand. That is before closing costs.
Now try a thinner file. Suppose your first mortgage is at 60% of value. The 70% cap leaves 10% of the current property’s value. At that size the line funds a down payment only on a much cheaper rental, or it covers part of the cash needed and you cover the rest.
Leverage matters here too. Some select high-leverage DSCR purchase programs reach 85% LTV, which means 15% down, with roughly a 700+ score. That shrinks the down payment the line must cover. A lower required down payment can mean a smaller draw, a smaller line payment, and fewer limits to satisfy. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Two more mechanics shape the size of the draw.
- At least 75% of the line is drawn at closing. You cannot open a large line and leave it untouched without paying for it.
- An investment line uses a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats during both stages and never converts to fixed.
Will the DSCR Lender Accept the Cash?
That is the real question, and the answer splits three ways across a wholesale network. Some programs accept a fully borrowed down payment with documentation. Some cap the borrowed share. The strictest overlays want part of the down payment from unborrowed cash. A fully borrowed down payment can fail on that basis alone, even with strong rent coverage.
Because Lendmire shops multiple lenders, the useful move is to find which treatment applies before you draw. The decision depends on the borrower’s credit, leverage, property and documentation. It cannot be settled by one global rule.
Sourcing is the second hurdle. The deposit has to trace to the HELOC account and then to escrow, so it never looks like an unexplained cash infusion. A typical document set includes:
- The HELOC agreement or statement
- The draw and transfer record
- Bank statements showing the funds landing and moving to escrow
Seasoning expectations differ by lender. One BiggerPockets investor discussion also flags that a parent’s line cannot supply down payment funds, which fits the broader point: the line should be in your own name, on your own property.
Closing Costs, Reserves, and Why Borrowed Funds Behave Differently
Borrowed funds are often excluded from reserves.
Reserves vary by lender, leverage, loan size and transaction type. About 6 months of PITIA is common. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months. An open balance on a credit line is not reserves. The cash must be yours, sitting in an account.
For contrast, agency mortgage guidelines treat borrowed funds secured by an asset differently. Fannie Mae’s Selling Guide accepts such funds for down payment, closing costs and reserves, and it counts the payment on the secured loan as a debt. DSCR loans are not agency products, so those rules do not carry over. The comparison mainly shows why DSCR treatment of reserves differs from what many borrowers expect.
Who Fits and Who Does Not
The investor who fits is usually self-employed or has irregular income that shows up better in bank deposits than on a tax return. That investor holds title personally or in a revocable trust. They have meaningful equity in a current property and a 700-plus score.
The investor who does not fit is easy to spot. Title is held in an LLC, which the bank statement line cannot accept. A property already deeded to an entity needs a vesting change first, or a DSCR cash-out refinance instead. A borrower with more than 15 financed properties is not eligible. A borrower is also limited to three lines, with combined exposure capped on each wholesale program.
Property type matters on the security side. Single-family, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use or agricultural zoning are not. Availability is also narrower than DSCR.
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. The CFPB’s Regulation Z separately sets rules on when credit to buy or improve rental property counts as business purpose, and the treatment changes for owner-occupied rentals. A line on your own home is a different matter, because that credit is secured by the residence.
The Part the DSCR Number Does Not Show
DSCR compares rent to the new property’s PITIA only. The payment on your credit line is usually not in that ratio. It still comes out of your pocket every month.
So rent has to cover two obligations: the DSCR loan and the line. Clearing 1.00 on the new rental says nothing about repairs, vacancy, management, utilities or capital expenses, all of which sit outside the calculation. A file that clears the ratio can still run thin once the line payment lands.
Leverage stacking is the second issue. When a line funds the down payment, total borrowing across both properties approaches the full purchase price of the new rental. One BiggerPockets investor frames a long hold on this structure as borrowing 100% of the property’s value. That framing is a good stress test: could you carry both payments if rents softened or the line’s variable pricing moved against you?
Exit plans matter as well. Investors in a separate BiggerPockets discussion repeatedly say a line suits short-hold strategies such as BRRRR or flips better than permanent down payment capital. A line secured by your home puts the home at risk if you default.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Should You Use the Line or Skip It?
Use it when the equity is deep, the purchase lender accepts borrowed funds, and rent comfortably covers both payments. In those cases a line can unlock a rental you could not otherwise buy yet, without selling the current property.
Skip it when any of these apply:
1. The first mortgage already consumes most of the 70% CLTV cap.
2. The title is in an entity and you cannot or will not move it.
3. The purchase lender wants unborrowed cash and you have none.
4. Rent covers the new loan but leaves no room for the line payment.
5. You intend to hold the rental for decades and have no plan to pay the line down.
A DSCR cash-out refinance on the existing property is the main alternative. It can replace the first mortgage with a larger one and may allow entity title. Cash-out on standard rentals tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. For short-term rental collateral, the cash-out ceiling is 70%. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Cash-out is a different decision, though. It resets the first loan and gives up whatever structure you have. A DSCR HELOC is another variant, qualified on rent instead of deposits, with vesting and minimums that differ by program. Whether the bank statement line, a DSCR HELOC or a cash-out fits depends on title, existing loan terms and the purchase target.
Practical Sequence
1. Run the equity formula on the securing property: value times 70%, less all liens.
2. Check eligibility: 700 or higher credit, individual or revocable trust title, eligible property type, and debt-to-income at 50% or lower.
3. Ask how the purchase lender treats borrowed funds before you draw.
4. Close the line before you shop. A line that is not funded can stall the file.
5. Draw and document the cash trail into your own account.
6. Size reserves separately from the borrowed down payment and closing costs.
7. Stress-test both payments against realistic rent.

Frequently Asked Questions
Can the line be larger than the down payment I need?
Yes, but the size of the draw matters. At least 75% of the line is drawn at closing, so a line far larger than the target down payment means you carry a balance you may not need. Size the line to the down payment and any closing costs you plan to cover with it, not to the maximum available.
Does a higher credit score raise how much I can borrow?
Not on an investment line. Below 700 the investment line is not available at all. Score still matters on the DSCR purchase side, where most programs want around 660 and 700+ opens the strongest leverage tiers.
Does the line payment hurt my DSCR?
Usually it does not appear in the ratio, which compares the new property’s rent to that property’s own PITIA. The payment still reduces your real cash flow, and a purchase lender may review your overall debt picture separately. Treat the ratio and your cash position as two different tests.
Can I take the line against a property held in an LLC?
Not with this product. Title must be held by an individual or a revocable living trust. A property deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance may fit better, subject to program terms.
Is any of this a zero-down DSCR purchase?
No. Purchase leverage on most files is 75%-80% LTV, and select high-leverage programs reach 85% LTV with roughly a 700+ score. The line only changes the source of the down payment cash. Whether a lender accepts it as the whole down payment depends on that lender’s treatment of borrowed funds.
