The Quick Read: The right home equity line is the one that fits the property securing it, your credit profile, and the purchase lender’s rules on borrowed funds. A HELOC does not buy the house; it supplies cash for the down payment and closing costs, while a separate purchase loan, usually a DSCR loan for an investor, buys the property.
- On the network Lendmire works with, an investment-property line tops out at 70% CLTV, with a 700 minimum credit score.
- Primary-residence and second-home lines can reach 90% CLTV, but only at 720 or better.
- Your HELOC payment does not enter the new property’s DSCR, but it still comes out of your real cash flow.
- Whether the purchase lender accepts borrowed funds is program-specific, so ask before you draw.
- Entity-held properties, such as those titled in an LLC, cannot secure these lines.
What Does a HELOC Actually Do in a Rental Purchase?
A HELOC is a revolving line of credit secured by property you already own. In a purchase it supplies cash, nothing more. The deed to the new house is financed by a second loan, and for most investors that second loan is DSCR-based.
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.
Lendmire is a mortgage broker, not a lender. It places files with wholesale HELOC lenders and DSCR lenders, so the question “which program is best” really becomes “which program fits this borrower and this collateral.” Two decisions drive that answer:
1. Which property secures the line? Your home, a second home, or a rental you already own.
2. Will the purchase lender accept the borrowed cash? Some programs do. Others want the down payment to come from the borrower’s own funds.
Get both right and the rest is arithmetic.
How Does Underwriting Treat Each Piece, Step by Step?
Each loan is underwritten on its own terms, and the two files barely overlap.
Step 1: Pick the collateral. The property you pledge sets the leverage ceiling, the credit floor and the risk. A line on your residence puts your home behind a business purchase. A line on a rental puts that rental behind the next one.
Step 2: Qualify the line on you, not the property. A HELOC is a personal-credit file. The lender reviews credit, debt-to-income, and the value of the collateral. On the network’s programs, DTI tops out at 50%, with 45% as the ceiling for credit profiles from 600 to 679. The lender reviews your file on the interest-only payment calculated on the maximum draw, so a large line weighs on the file even if you plan to draw less.
Step 3: Open the line before you go under contract. A line that is opened, funded and documented before an offer gives the purchase lender a clean paper trail. Opening it mid-contract invites questions.
Step 4: Draw and document. On the network’s programs, at least 75% of the line is drawn at closing. Plan around that. You cannot open a large line and simply leave it undrawn as a standby reserve, so size it to the cash you actually need.
Step 5: Close the DSCR purchase. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The purchase lender then compares that rent to principal, interest, taxes, insurance and any HOA dues.
Step 6: Carry both payments. The HELOC payment is a personal obligation. It stays out of the new property’s coverage ratio, but it competes for the same monthly cash.
Which Collateral Is Best: Home, Second Home, or Rental?
Collateral choice sets your ceiling more than any other variable. Here is how the network’s programs split by occupancy.
| Collateral | Max CLTV | Credit floor | Max line |
|---|---|---|---|
| Primary residence | 90% (720+ only) | 600 | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 90% (720+ only) | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
A few details sit behind that table:
- The top tiers are narrow. On a primary residence, 90% CLTV applies only at 720 or better and only up to a $500,000 line. At a 700 profile the ceiling on a primary drops to 85% for lines up to that size.
- A line above $500,000 is primary-residence only. It requires a credit profile of 700 or better (720 on the programs with the longer interest-only runway), caps at 75% CLTV, and needs a full appraisal.
- Lines of $500,000 or less usually run on an automated valuation instead of a traditional appraisal. You can still request a full appraisal.
- Investment lines run a 5-year interest-only draw followed by a 25-year repayment period. Primary-residence and second-home lines add a shorter option: a 3-year draw with a 17-year repayment.
Market surveys report that lenders across the broader market typically cap investment-property lines at 80% LTV, according to Experian. On the network Lendmire works with, the investment-property ceiling is 70% CLTV. Plan your math on the lower number.
Here is a quick sketch in percentages only. Say your primary home already carries a first mortgage equal to 55% of its value. At 720 credit, a 90% CLTV ceiling would leave room for a line up to 35 points of value, subject to the line cap and valuation. The same house with a 700 profile sits under an 85% ceiling, which shrinks the room by five points. The same exercise on a rental runs against 70%, so a rental already at 60% leaves a thin 10-point cushion.
The tradeoff is real. A line on your residence offers more room but puts your home at risk. A line on a rental protects your home but caps you lower and requires stronger credit. Neither is “best” in the abstract.
What Do Purchase Lenders Think About Borrowed Down Payments?
Acceptance varies by program. A DSCR purchase file typically carries 20% to 25% down, and select programs reach 85% LTV (15% down) with a score near 700 or better. Most files land at 75% to 80% LTV on a purchase.
Where that down payment comes from is a separate test. Three patterns show up across the wholesale network:
- Accepted with documentation. Some programs allow the down payment to come from a HELOC on another property, provided the funds are seasoned and sourced.
- Accepted for closing costs only. Others take borrowed funds for part of the cash to close but want reserves from your own assets.
- Not accepted. A few want the down payment in the borrower’s own account, with no new lien behind it.
One distinction matters here. A second lien recorded against the property you are buying is the structure DSCR lenders object to most. A line secured by a different property you already own is the more widely accepted arrangement. Reserves are usually the stricter test. Programs commonly want around 6 months of PITIA in your own liquid assets, though 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. Borrowed cash often does not count toward them.
Ask the purchase side first, before you open the line. A line approved for you does not obligate a DSCR lender to accept it.
How Much Rental Coverage Do You Need?
The DSCR divides monthly rent by the property’s full payment (principal, interest, taxes, insurance and HOA). Select programs start at 1.00, meaning rent just covers the payment. Stronger ratios open better pricing and more leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted accordingly.
Clearing 1.00 is not the same as positive cash flow. The ratio ignores repairs, vacancy, management, utilities and capital expenses. It also ignores your HELOC payment. A rental that covers its own loan at 1.10x can still run negative once a floating, interest-only HELOC payment sits next to it.
The loan basics from the rest of the network:
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Cash-out refinance: tops out near 75% LTV, with about 6 months of seasoning as the common expectation.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders), with 30-year fixed structures the norm above $2,500,000.
- Structures: the 30-year fixed is the spine, with 40-year terms, interest-only periods and ARMs available through select lenders.
- Ineligible properties: DSCR loans on manufactured homes, log homes and barndominiums are not offered.
For the full mechanics, Lendmire’s complete DSCR loans guide walks through the purchase side in detail.
Where the General Rule Breaks
Several edge cases catch investors who assume the standard path.
Entity-held rentals. The HELOC programs described here require title in an individual’s name or an inter vivos revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance is the better route. This is the sharpest structural difference between the two products.
Property types. Single-family, 2-4 units, PUDs, townhomes and condominiums (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use or agricultural-zoned properties are not. Two-to-four-unit properties need a 640 score on the programs with the longer interest-only runway.
Texas primary residences. A Texas primary is a homestead. It caps at 80% combined loan-to-value, waits 12 days, follows a one-lien-at-a-time rule and needs 12 months of seasoning. Texas second homes and investment properties are treated as non-homestead transactions and follow the standard tables.
Listed properties. A property currently listed for sale, or listed within the past 60 days, is ineligible in several states. Check this before you pledge a house you are thinking of selling.
Exposure limits. A borrower is limited to three lines and, depending on the program, $750,000 or $2,000,000 in combined exposure. An investor with more than 15 financed properties is not eligible.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history splits by program. One program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure or short sale at 4. Another declines that history regardless of age.
Availability. The HELOC programs are 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. That is narrower than the 41-market DSCR footprint.
What Does the Risk Picture Look Like?
The risks are structural, not exotic.
Pricing on these lines floats across both the draw period and the repayment period and never converts to fixed. The Ask CFPB explainer notes that HELOCs usually carry variable rates, so payments can change from month to month. A fixed-rate DSCR loan sitting next to a floating line is a real mismatch.
The draw period is interest-only, then the line moves into repayment. The CFPB HELOC brochure describes both the interest-only draw payments and the way a variable-rate payment can move even when you draw nothing more. When repayment begins on the amortizing schedule, the payment steps up. An investor who planned around the interest-only number can be caught off guard.
The line is secured by a house. If you pledge your residence and the rental underperforms, your home carries the downside.
Three habits reduce the damage:
- Run your numbers on the amortizing payment, not just the interest-only one.
- Keep a cushion of your own cash beyond the down payment.
- Plan an exit. A HELOC fits a short hold or a planned refinance better than a 30-year hold.
When Is a HELOC the Wrong Tool?
Sometimes the best answer is a different instrument. Compare the options by what they do well.
| Option | Choose it if | Main tradeoff |
|---|---|---|
| HELOC | You need flexible cash for a down payment | Floating payment, lien on collateral |
| Home equity loan | You want a fixed lump sum | Less flexibility |
| Cash-out refinance on a rental | The rental has strong coverage and equity | Resets the existing loan |
| Personal loan | You need small, short-term cash | Short terms, higher monthly strain |
| Bridge loan | You are selling and buying at once | Interest-only, repaid by a later refinance |
A DSCR cash-out refinance is worth a serious look when the rental you would pledge already has strong rent coverage. It converts equity into cash using the same property-level logic as the purchase, with no personal income test. Lendmire’s piece Best DSCR HELOC Program for Buying Another Rental House covers that comparison in more depth.
For investors who would rather pledge a rental than a residence, Lendmire’s piece Best Investment Property HELOC Program to Buy Another Home goes further into the 70% ceiling and its tradeoffs.
How Do You Choose? A Short Decision Frame
If you want the best program for your situation, work through four questions in order.
1. What are you pledging? Residence, second home, or an individually titled rental. The occupancy sets the ceiling.
2. What is your credit profile? 720+ opens the top tiers. A 700 score is the entry point for investment lines. Below 640, options narrow to primary residences.
3. How much cash do you need? A line is sized for 75% or more drawn at closing, so over-sizing costs you interest.
4. Will the purchase lender accept it? Confirm acceptance and the reserve treatment before you open anything.
An investor with 720+ credit, a lot of equity in a primary home, and a short-hold plan sits in a very different place from one with a 690 profile and one rental held in an LLC. The first may fit a primary-residence line. The second may be better served by a DSCR cash-out refinance after a vesting change.
Key Terms Defined
CLTV (combined loan-to-value): All loans secured by a property, added together and divided by its value.
Draw period: The stretch when you can borrow from the line, interest-only on these programs.
Repayment period: The stage after the draw period, when the balance amortizes.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s full monthly payment.
Reserves: Liquid assets, usually counted in months of PITIA, that you hold after closing.
Seasoning: The time funds or a loan have been in place before a lender will count them.
Frequently Asked Questions
Can I use a HELOC for the down payment on a rental?
Often yes, but acceptance depends on the DSCR program. Some programs take borrowed funds with documentation. Others want the down payment from your own assets. A line secured by another property you already own is more widely accepted than a second lien on the property you are buying.
Does the HELOC payment lower my DSCR?
It does not enter the new property’s ratio, since that ratio compares rent to the property’s own payment. It still reduces your real cash flow, so an investor who qualifies at 1.00x or above can still run negative once the line is serviced.
Can an LLC take out a HELOC on a rental?
Not on these programs. Title must sit with an individual or a revocable living trust. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance may be the better path, subject to program terms.
How much can I borrow against an investment property?
On the network’s investment-property program, the ceiling is 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000. Market surveys report 80% elsewhere, but that is not the network figure. All figures are subject to lender guidelines and full file review.
What if the numbers do not work on a HELOC?
That is a signal to consider a DSCR cash-out refinance, a smaller purchase, or more cash down. Reaching for a bigger line to force a deal is usually the wrong fix.
