The Quick Read: A home equity line supplies cash for the down payment, closing costs and reserves, not the whole property, so its purchasing power equals the line you can open divided by the down-payment share the DSCR loan requires. A separate DSCR loan closes the purchase. The size of the line depends on equity, and whether the purchase lender accepts borrowed funds depends on the program.
- An investment-property line tops out at 70% CLTV and $500,000, with a 700 minimum credit score.
- A primary-residence line can reach 90% CLTV, but only at 720+ credit.
- Most DSCR purchases run 75%-80% LTV, so the line must cover roughly 20%-25% down plus costs.
- The HELOC payment sits outside the DSCR ratio but inside your own cash flow.
- Reserves are a separate pot, and borrowed money may not count toward them. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Everything below is subject to lender guidelines and full file review. Nothing here is a commitment to lend.
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: A revolving line of credit secured by property, drawn as needed, with a draw period followed by repayment.
CLTV: Combined loan-to-value, which adds every lien on the property and divides by its value.
DSCR: Debt service coverage ratio, calculated as monthly rent divided by the new loan’s PITIA (principal, interest, taxes, insurance and any HOA dues).
Reserves: Liquid funds held after closing, counted separately from the down payment.
Seasoning: How long money has sat in your account before a lender will treat it as yours.
How Do a HELOC and a DSCR Loan Split the Job?
The HELOC is underwritten to you. The DSCR loan is underwritten to the property. One creates cash. The other buys the asset.
| Factor | HELOC | DSCR purchase loan |
|---|---|---|
| What it tests | Borrower credit, equity, DTI | Property rent vs. PITIA |
| What it funds | Down payment, costs, reserves | The purchase itself |
| Title | Individual or revocable trust | Entity ownership possible, subject to program terms |
| Collateral | Existing home or rental | The new property |
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.
For the full picture of how the purchase side works, Lendmire’s complete DSCR loans guide covers it end to end.
How Do You Calculate What the Line Can Give You?
Start with the formula: value times the allowed CLTV, minus what you already owe. A CFPB HELOC booklet illustrates this logic with a $100,000 home, a 75% limit and a $40,000 balance. The lender takes the percentage of appraised value, then subtracts the mortgage.
On this wholesale network, the ceiling depends on occupancy.
- Investment property: 70% CLTV, 700 minimum score, $25,000 to $500,000. A 720 score reaches the same 70% cap as 700, so higher credit buys eligibility, not leverage.
- Primary residence: up to 90% CLTV, but only at 720+ credit. Lines above $500,000 are primary-residence only, cap at 75% CLTV, need a full appraisal, and require 700 or better (720 on the longer-runway structure).
Market-wide surveys, such as NerdWallet’s investment-property HELOC explainer, report limits as high as 80% on investment lines, though many lenders sit lower. The network figure for an investment line is 70%.
Run it on a rental. Say the first mortgage sits at 45% of value. Under a 70% cap, roughly 25 points of value remain to draw against. If the first mortgage sits at 50%, about 20 points remain. That is the ceiling, before any property-level checks.
Turning Line Size Into Purchase Price
Purchasing power is the usable line divided by the down-payment share. Equity is the limiting factor, and the math is blunt.
| Down-payment share | Line needed per $1 of price |
|---|---|
| 20% (80% LTV) | 20 cents plus costs |
| 25% (75% LTV) | 25 cents plus costs |
| 15% (85% LTV, select programs) | 15 cents plus costs |
Take that 25-point line on a rental. On a purchase of equal value at 75% LTV, the line becomes only the 25% down payment. Nothing is left for closing costs, rehab or reserves. So the real purchase price a line supports is smaller than the raw division suggests. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Select high-leverage purchase programs reach 85% LTV at roughly a 700+ score. That lowers the cash needed per dollar of price, though leverage caps, credit floors and reserve rules still apply. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
An investment line caps at $500,000 total. There is no tier above it. If the line, not the property, is your constraint, that cap is the real ceiling on this route.
Down Payment, Closing Costs and Reserves Are Three Pots
Back into the number. Take the target price and multiply by the down-payment percentage. Add closing costs and any rehab budget. Then add reserves.
Reserves are the trap. Across most programs on the network, reserves commonly run around 6 months of PITIA. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived. Larger loans typically step up to about 9 months. It varies by lender, leverage, loan size and transaction type.
Borrowed money may pass as down payment and still fail as reserves. A lender that accepts a documented HELOC draw toward cash to close may want reserves verified in your own accounts. Confirm which pot the line can fund before you draw.
Will the DSCR Lender Accept Borrowed Funds?
It depends on the program. Across the network, stances range from accepting a documented HELOC draw toward the down payment, to capping the borrowed share, to treating reserves differently from cash to close. Seasoning is the common friction point. BiggerPockets investors describe drawing early so the deposit ages past the statement window, though much of that discussion concerns DTI-based loans rather than DSCR.
The paper trail a purchase lender typically wants:
- HELOC closing documents and the draw confirmation.
- Statements showing the cash landing in your account.
- Proof of funds for down payment, closing costs and reserves.
- A credit report showing the new line as a liability.
Unexplained large deposits create underwriting conditions. Ask the purchase lender before drawing, not after. A broker who sees many programs can tell you which ones are friendlier to borrowed funds.
Does the Rent Still Cover Two Payments?
The DSCR ratio compares rent to PITIA on the new loan only. The HELOC payment is normally outside the formula. A borrower financing 25% down with a line at a 75% LTV purchase is financed close to 100%, and the ratio still looks clean.
That clean ratio can mislead. Clearing 1.00 is not positive cash flow. Repairs, vacancy, management, utilities and capex sit outside the calculation, and so does the HELOC.
Consider a scenario where a purchase clears roughly 1.2x on the DSCR loan. If the rent was never asked to carry the line payment, the line comes out of your own pocket. A larger down payment lowers the DSCR loan payment and can lift coverage, but it never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Stress-test four questions:
- Can your own income carry the line through a vacancy?
- Can you absorb the step-up when the interest-only draw ends?
- Will reserves remain after closing?
- What happens if the line is frozen?
Investment lines on the network run a 5-year interest-only draw, then a 25-year repayment. At least 75% of the line is drawn at closing, and pricing floats through both periods. The CFPB’s HELOC brochure confirms variable-rate payments can change even without new draws.
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.
Which Property Backs the Line?
The collateral choice changes both leverage and risk.
| Collateral | Leverage ceiling | Risk |
|---|---|---|
| Primary home | Up to 90% CLTV at 720+ | Residence sits behind the next deal |
| Rental held personally | 70% CLTV | Default risk confined to the rental |
| LLC-titled rental | Not eligible as-is | Needs vesting change or DSCR cash-out |
LLCs, corporations, partnerships and irrevocable or land trusts cannot hold title on the line. Title must be an individual or a revocable living trust. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead. NerdWallet notes the property is the collateral on any HELOC, so the lien position matters.
Honestly, the primary-home line is the more powerful tool and the riskier one. Investors with a single rental and a large first lien often find little usable equity at all.
Where the General Rule Breaks
- Property types. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered on the line.
- Exposure. A borrower can hold up to three lines. Owning more than 15 financed properties disqualifies the borrower.
- Availability. Home equity lines are offered in Lendmire’s 16 full-service states only, narrower than the 41-market DSCR footprint.
- Timing. You cannot open a line on a property you have not bought yet. It must be open and funded before you go under contract.
- BRRRR use. Some investors use the line as short-term funding, then refinance and repay it. That works only if the refinance appraises and qualifies.
- DTI-based purchases. A conventional or other DTI-based purchase counts the HELOC payment. DSCR generally does not.
When a HELOC Isn’t the Right Tool
Diagnose which gate you are failing. If equity is thin, a DSCR cash-out on an existing rental, a partner, or cash may fit better. If credit is under 700, the investment line is closed to you, though a primary-home line may still be open. If title sits in an LLC, the line is out unless you change vesting. If the property fails the 1.00 benchmark that many select programs start from, more equity will not fix it. Sub-1.00 coverage is available through select lenders in the network, with leverage and terms adjusted.
Lendmire’s piece How Much Rental Purchasing Power a Primary Home HELOC Creates walks through the higher-leverage collateral case. Lendmire’s piece How Much a Bank Statement HELOC Can Fund Toward a Rental Purchase covers the alternative documentation path.
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.
The Order of Operations
1. Calculate usable equity: value times allowed CLTV, minus liens.
2. Back into the total cash needed: down payment, costs, rehab and reserves.
3. Ask the purchase lender how borrowed funds are treated.
4. Open the line, then draw and document the cash.
5. Go under contract with proof of funds in hand.
6. Plan the exit: refinance, paydown or a rent-funded payoff.

Frequently Asked Questions
Can a HELOC buy a rental property outright?
A HELOC supplies cash, not a purchase. If the line is large enough you could pay for a low-priced property with it, but a financed purchase uses a separate loan. The line is capped by equity, and an investment-property line stops at $500,000.
Can HELOC money be the down payment on a DSCR loan?
Often, but the purchase lender decides. Programs differ on whether they accept a documented draw, cap the borrowed share, or require seasoning. Confirm before drawing so the paper trail matches what the lender wants.
Does the HELOC payment count in the DSCR ratio?
Generally no. The ratio compares rent to the new loan’s PITIA. The payment still comes out of your cash flow, so check that your income or the property’s margin can carry both.
How much can I borrow on an investment property?
Up to 70% CLTV, between $25,000 and $500,000, at a 700 minimum score. A 720 score does not raise the cap. A primary residence can reach 90% CLTV, but only at 720+ credit.
Can I use an LLC-owned rental to secure the line?
Not as titled. The line requires an individual or a revocable living trust. A property held in an LLC needs a vesting change, or a DSCR cash-out refinance may fit better.
