The Quick Read: A home equity line supplies cash, and a separate DSCR purchase loan buys the rental, so the investor clears two independent underwriting decisions. The line is judged on the borrower’s equity, credit, and debt load. The purchase loan is judged mainly on whether the new rental’s income covers its own payment, and each purchase lender sets its own rule on borrowed funds.
- On an investment property, the network’s equity-line ceiling is 70% CLTV, with a 700 minimum score and a $500,000 maximum line.
- On a primary residence, the ceiling reaches 90% CLTV only at a 720 or better credit profile.
- Most DSCR purchases land at 75%-80% LTV, so the buyer still needs 20%-25% down plus closing costs and reserves.
- The line’s payment generally does not enter the new loan’s coverage ratio, but it still has to be paid from the investor’s own cash flow.
How Does a HELOC Fit Into a Rental Purchase?
A HELOC never buys the property. It converts equity in a property you already own into cash. You move that cash into a documented account and bring it to the purchase as the down payment, closing costs, or both.
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.
Yahoo Finance notes that homeowners can use equity in a primary residence for a down payment on an investment property, provided they have enough equity to qualify. It adds that the funds can cover closing costs and other expenses up to the approved limit.
Two files exist in this deal. The first is the line, which is a loan against your existing property. The second is the DSCR purchase loan on the new rental, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Each file has its own documents, its own reviewer, and its own approval. Neither lender is bound by the other’s decision.

Key Terms Defined
CLTV: Combined loan-to-value, which adds every lien on a property (the first mortgage plus the line) and divides by the property’s value.
Draw period: The stretch of time when you can borrow against the line, usually paying interest only.
Repayment period: The stretch after the draw ends, when the balance amortizes and the payment steps up.
DSCR: Debt service coverage ratio, calculated as monthly rent divided by the monthly payment of principal, interest, taxes, insurance, and any HOA dues.
Reserves: Liquid funds the purchase lender wants to see after closing, separate from the down payment.
Sourcing: The paper trail showing where the down payment money came from.
Which Property Should Secure the Line?
The line can sit on your primary residence or on a rental you already own. The choice changes the ceiling, the underwriting focus, and what you risk if payments stop.
| Factor | Line on primary residence | Line on an existing rental |
|---|---|---|
| Collateral at risk | Your home | The rental |
| Max CLTV on this network | Up to 90% at 720+ credit | 70% |
| Minimum score | 600 program floor | 700, no lower tier |
| Max line size | $750,000 | $500,000 |
| Underwriting focus | Equity, credit, debt load | Same, plus the rental’s profile |
Primary-home lines are underwritten on equity, credit, income, and total debt, according to Taxstra’s breakdown of rental and primary-home lines. Lines secured by a rental get stricter treatment, and Benzinga lists the usual file contents: proof of income, tax returns, rental agreements, and proof of insurance.
On the investment side, the table is simple. A 720 score and a 700 score both reach 70% CLTV. Credit above 700 buys eligibility, not extra leverage. Because an investment line caps at $500,000, it sits in the automated-valuation lane and commonly closes with no traditional appraisal.
A primary-residence line works differently, and only a primary residence can carry a line above $500,000. Such a line requires a credit profile of 700 or better (720 on the 5-year-draw structure described below), caps at 75% CLTV, and needs a full appraisal. A Texas primary residence is a homestead and caps at 80% combined loan-to-value. Texas second homes and investment properties follow their standard tables.
How Does Underwriting Treat the Line, Step by Step?
The line follows a fixed sequence. Each step below is a place where a file can stall for missing paper.
1. Pick the collateral and confirm eligibility. Eligible property types for the line are single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible. In Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington, a property listed for sale, or listed within the past 60 days, is ineligible.
2. Check title and vesting. Title must be held by the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest structural difference from a DSCR loan, which can close in an LLC subject to lender program eligibility. A rental already deeded to an LLC needs a vesting change before it can secure a line, or a DSCR cash-out becomes the better tool.
3. Qualify on credit and debt load. The program floor is 600, using a single-bureau score keyed to the primary wage earner, and the report can be no more than 90 days old at closing. Maximum DTI is 50%, with 45% for credit profiles from 600 to 679. The payment used for qualifying is the interest-only payment on the maximum draw, not on what you plan to borrow.
4. Run valuation. Lines at or below $500,000 ordinarily use automated valuation, though a higher CLTV may trigger a secondary valuation. A borrower may request a full appraisal in any case.
5. Close and draw. At least 75% of the line is drawn at closing on both structures. A line cannot sit fully undrawn waiting for a deal, so size it to the purchase and not to the largest number that qualifies. After closing, the minimum subsequent draw is $1,000, except in Texas, where it is $4,000.
6. Move the draw into a dedicated account. Taxstra recommends borrowing only what the deal needs (down payment, closing costs, and a rehab buffer) and keeping the draw in its own account. A dedicated account also gives the purchase lender a clean trail to follow.
Availability is narrower than the DSCR side. The home equity line is offered in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. The DSCR footprint covers 41 markets, including Washington, D.C.
What Structures Exist for the Line?
The network places lines as a standalone first or second lien. Two draw structures exist on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year amortizing repayment. The other, the 5-year-draw structure, runs a 5-year interest-only draw followed by a 25-year repayment. Tennessee shortens both, to 3 years and 12 years on the first, and 5 years and 10 years on the second.
Investment lines use the 5-year draw and 25-year repayment structure only. Pricing floats during both the draw and repayment periods and never converts to fixed.
The CFPB’s HELOC explainer describes the same shape in general terms. Draw periods can last about ten years, repayment often runs ten or twenty years, and monthly payments are often significantly higher once repayment begins. The CFPB’s HELOC brochure confirms that HELOCs typically carry variable pricing, so payments change over time.
A few other limits matter if you plan to repeat this move:
- A borrower is limited to three lines.
- Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the 5-year-draw program.
- A borrower owning more than 15 financed properties is not eligible.
- Bankruptcy needs 4 years of seasoning from discharge or dismissal.
- Investment files season a foreclosure over 7 years, and a deed-in-lieu, pre-foreclosure, or short sale over 4 years.
How Does the Purchase Lender Treat the Borrowed Money?
This is the gate that decides the plan. The HELOC lender approves the line, but the DSCR purchase lender decides whether borrowed money counts toward the down payment, closing costs, or reserves. Programs across the network handle this differently, and a program can treat borrowed funds one way for the down payment and another way for reserves.
Plan for the draw to be sourced like any large deposit. Reserves deserve a separate check, because reserve rules are usually stricter than down payment rules. Reserves vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common. Conservative rate-term files at modest leverage and under $1,500,000 can see reserves waived, while loans above that size typically step up to about 9 months. Confirm the borrowed-funds rule for each pot of money before the line is opened, because a closed line cannot be un-drawn.
What the DSCR Side Actually Measures
The purchase loan compares rent to PITIA. It is not a personal DTI calculation. The line’s payment generally does not enter that ratio, and that is the whole reason investors pair equity-line cash with DSCR financing. On a conventional loan, the picture is different. Taxstra notes that the line’s payment counts toward debt-to-income on a conventional qualification.
Here is the leverage math on the purchase side, using percentages only. Most DSCR purchases land at 75%-80% LTV, which means 20%-25% down, though select programs reach 85% LTV (15% down) with roughly a 700+ score. Add closing costs and reserves on top of the down payment, and the line has to cover all of it, because all of it must be on hand. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Strong rental coverage never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
On coverage itself, 1.00 is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. No-ratio structures exist only through select lenders, generally for borrowers who already own a primary residence.
Clearing 1.00 is not the same as positive cash flow. The ratio looks only at rent against PITIA. Repairs, vacancy, management, utilities, and capex sit outside it. A rental that clears the number can still lose money each month once the line’s payment is added.
What the Stack Looks Like in Practice
Run the numbers on three ways to fund the same purchase, all at 75% LTV on the DSCR loan. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
| Funding path | Down payment source | What the investor carries |
|---|---|---|
| Savings only | Cash on hand | The new mortgage only |
| Part line, part savings | Draw plus cash | Mortgage plus a smaller line balance |
| Mostly line | Draw covers most of 25% down | Mortgage plus a large interest-only balance |
The DSCR ratio on the new loan is the same in all three rows, because it reflects only the new property’s rent against its own payment. The investor’s real position is not the same. In row three, the investor holds the property with almost no equity, and two payments come from one rental’s income.
Yahoo Finance points out that draw periods typically involve interest-only payments. That makes the stack look light during the draw and heavier later. The line’s payment steps up when repayment starts, so a rental that is still stabilizing when the draw ends carries the most risk.
A fair stress test asks four questions:
- Does the new rental cover its own PITIA with room left over?
- Can the rent and the investor’s other income also carry the line’s payment?
- What happens if the line’s variable pricing moves up?
- What is the written plan to pay the line down, or to refinance the new property and reset the line?
Where the General Rule Breaks
Fully borrowed down payment. Whether a program accepts a 100% borrowed down payment varies by program. Even where it is allowed, the purchase loan’s leverage cap and credit floor still apply, and the investor ends up with no equity of their own in the deal.
Borrowed reserves. Reserve rules are the strictest pot. A program that accepts a borrowed down payment may still want reserves from the investor’s own funds. Ask before drawing.
LLC-held rentals. A rental titled in an LLC cannot secure the line, as covered above. Deeding it out to an individual can disturb existing financing, insurance, and liability protections, so it deserves its own conversation.
Draw expiry. The CFPB’s explainer warns of payment shock when repayment begins. On an investment line, the 5-year draw is the only structure available, so the step-up date is a fixed point to plan around.
Early exit through refinance. Refinancing out of the line by refinancing the new rental sounds clean, but a DSCR loan can carry a prepayment penalty. That cost belongs in the exit plan. Compare it against a cash-out refinance on the source property, which is a new loan with its own fees.
Tax. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Misconceptions Worth Clearing Up
A HELOC means zero down. It changes where the down payment comes from. It does not remove the down payment, and the purchase loan keeps its own cap and credit floor.
Every lender accepts borrowed funds. Lenders vary, which is why the purchase lender’s rule is checked first.
DSCR means no paper trail for the down payment. DSCR drops personal DTI from the purchase loan. It does not drop sourcing. Funds still need documentation.
The line’s payment lowers the DSCR. It generally does not enter the ratio. It still comes out of your pocket.
A rental line is as easy to get as a home line. It is a stricter product, with a lower ceiling and a higher credit floor on this network.
The Investor Decision
The move makes sense when four things line up. The investor has real equity beyond what the line will use. The purchase lender accepts borrowed funds for each pot. The new rental covers its own payment with room to spare. The investor can carry the line from outside income if the rental has a bad stretch.
It stops making sense when the line would fund nearly all of the cash needed, when reserves would also be borrowed, or when the plan depends on refinancing out before the exit cost is known. The first rental and the fifth are different here. By the fifth, exposure limits and the three-line cap become part of the planning.

Frequently Asked Questions
Can a HELOC cover the whole down payment on a rental?
It can cover part or all of it in some cases, but the purchase lender sets the rule on borrowed funds. Most DSCR purchases need 20%-25% down, plus closing costs and reserves. Reserves are often treated more strictly than the down payment, so confirm the program’s rule before drawing.
What is the maximum CLTV on an investment property line?
The network ceiling on an investment property is 70% CLTV, and the minimum credit score is 700. Scores of 720 and 700 both reach the same 70% tier. The maximum line is $500,000. The 90% ceiling applies only to primary residences, and only at a 720 or better credit profile.
Does the line’s payment hurt the new DSCR ratio?
Generally no. DSCR compares the new rental’s rent to its own PITIA, and the line’s payment is a borrower-level obligation. That payment still has to be paid from your own cash flow, so a rental that clears 1.00 can still run short once both payments land.
Can an LLC-owned rental secure the line?
No. Title must be held by an individual or an inter vivos revocable living trust. A rental already in an LLC needs a vesting change, or a DSCR cash-out refinance may fit better.
Can I open the line and leave it undrawn until I find a deal?
Not on this network. At least 75% of the line is drawn at closing on both structures, and pricing floats on the drawn balance. Size the line to the purchase you expect to make.
