The Quick Read: A home equity line does not buy the property; it supplies the down payment cash while a separate investor loan finances the rest, so the best program for your situation opens before you shop, sits on a property you can afford to risk, and leaves the rental able to cover its own loan payment.
- On an investment property, the equity lines in Lendmire’s wholesale network top out at 70% CLTV (combined loan-to-value, meaning all loans against the home as a share of its value). They also require a 700 minimum credit score.
- On a primary residence, the ceiling reaches 90% CLTV, but only with a credit profile of 720 or better.
- The DSCR purchase loan that finishes the deal typically runs 75%-80% LTV on a purchase, so plan on 20%-25% down. Select programs reach 85% LTV with roughly a 700+ score.
- Borrowed down payment funds are commonly accepted with a paper trail, but often not for reserves. Confirm with the purchase lender before you draw.
What Does a HELOC Actually Do in a Rental Purchase?
A HELOC is the cash source. A DSCR loan, an investor mortgage that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, is the acquisition financing. Two loans, two underwriting files, two payments.
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.
That distinction clears up most of the confusion around this topic. Investors search for the best HELOC program as if one product handles the whole deal. It doesn’t. The line pays the down payment and closing costs. The purchase loan pays the seller.
You can, in theory, spend the line on the whole price and own the property outright. That works on paper. It also means you borrowed close to 100% of the property’s value against your home. The rental then carries almost no equity cushion if values slip or a tenant leaves.
Availability is the next hurdle. BiggerPockets notes that many banks write home equity lines only on a primary residence, and that lines secured by a rental are harder to find. Across a wholesale network, we see the same pattern: the line is easiest to place on the home you live in, and the rules tighten sharply once the collateral is an investment property.
Because the purchase is business-purpose financing, the DSCR file does not review your personal debt-to-income ratio. The line’s own file does. That split shapes everything below.
If you want the full picture of the purchase side, Lendmire’s complete DSCR loans guide covers how those loans work end to end.
Key Terms Defined
HELOC: A home equity line of credit. You borrow against your equity as needed, up to a set limit.
CLTV: Combined loan-to-value. It counts your first mortgage and the new line together, as a percentage of the home’s value.
Draw period: The early stretch when you can borrow from the line. On the network’s investment lines, it is five years of interest-only payments.
Repayment period: The later stretch when you can no longer draw and the balance pays down fully. On investment lines, it runs 25 years.
DSCR: Debt service coverage ratio. It compares a property’s monthly rent to its monthly payment.
PITIA: Principal, interest, taxes, insurance, and association dues. This is the payment the DSCR ratio uses.
Reserves: Liquid savings a lender wants left over after closing, often counted in months of PITIA.
Seasoning: The waiting period a lender wants between events, such as owning a property for about six months before a cash-out refinance.
Vesting: How title is held. It decides whether the line is even possible.
How Do Lenders Underwrite the Line and the Purchase Loan?
The line and the purchase loan are judged separately, and each has a different gatekeeper. Here is the sequence on a typical file.
1. The equity test on the line. The lender sets a ceiling as a percentage of the home’s value, then subtracts what you owe. The CFPB’s HELOC booklet uses 75% of home value as an illustration of that method. That is a market-wide teaching figure. In this network, an investment-property line caps at 70% CLTV, and a primary residence can reach 90% CLTV only at 720 or better.
2. The personal file on the line. Expect a credit check, a debt-to-income review capped at 50%, and a valuation. The qualifying payment is calculated on the interest-only amount at the maximum draw, not the amount you plan to use.
3. Close the line before you need the cash. The line has to be open before the purchase contract calls for funds. Then you draw, and the money goes through your bank to the title company.
4. The DSCR file on the purchase. This lender looks at the rental’s income against its PITIA. A coverage ratio of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
5. The borrowed-funds check. This is the deciding gate. Programs differ on whether borrowed money can be the down payment source. On many files, it is accepted for the down payment and closing costs with documentation, and excluded from reserves. Some programs cap the borrowed share or want part of the down payment from your own cash.
6. The paper trail. Plan to provide the line’s terms, the draw record, bank statements showing the deposit, and the line’s statement.
Clearing 1.00 on the purchase does not mean the rental produces positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. The HELOC payment sits outside it too, yet it still leaves your bank account every month.
Which Property Should Secure the Line?
The property securing the line is the biggest choice you make. A line on your primary home reaches higher leverage and bigger sizes. A line on an existing rental is capped lower and can be much harder to place.
| Factor | Line on primary home | Line on existing rental |
|---|---|---|
| Max CLTV | Up to 90% (720+ only) | 70% |
| Minimum credit | 600 floor (640 second home) | 700 |
| Max line size | Up to $750,000 | $500,000 |
| Draw structure | 3-year or 5-year interest-only | 5-year interest-only |
| Typical valuation | Automated, or full above $500,000 | Automated, commonly no appraisal |
The investment-property tier is thin by design. A 720 score and a 700 score both reach 70% CLTV, so credit above 700 buys eligibility, not leverage. Below 700, there is no tier beneath it.
A line above $500,000 is for primary residences only, caps at 75% CLTV, and requires a full appraisal. An investment line never reaches that size. That means it almost always runs on an automated valuation, with no traditional appraisal. A borrower can still request a full appraisal in any case.
Risk differs too. A line on your home puts your home at stake for a rental’s performance. A line on a rental keeps the exposure on the investment side, but it has tighter limits.
What Does the Line Look Like After Closing?
Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. On primary residences and second homes, you can also choose a 3-year draw with a 17-year repayment. Pricing floats through both periods and never converts to fixed.
The CFPB describes a HELOC as an open-end line of credit with a draw period followed by a repayment period. It also warns that you could lose your home if you fall behind. That warning matters more when the home is collateral for someone else’s tenant.
Two structural facts surprise people:
- At least 75% of the line is drawn at closing. You cannot open a large line and leave it untouched. Interest runs on what you take. Size the line to the down payment and closing costs, not to your maximum equity.
- The payment steps up when the draw ends. The interest-only phase is gentle. The repayment phase is not. Your plan to refinance, sell, or pay down needs to land before then.
After closing, the minimum draw on later advances is $1,000 on the longer-draw structure the network stipulates. Plan your rental’s repayment path from the day you buy.
A Worked Example in Percentages
Say you own a primary home with a first mortgage at 50% of its value, and your credit profile is 740. The network’s ceiling for a primary residence at 720 or better is 90% CLTV. On paper, that leaves up to 40% of the home’s value as line capacity, before the size cap and the DTI test.
You do not draw that. You find a duplex and plan a DSCR purchase at 75% LTV, meaning 25% down. The line covers that 25% plus closing costs. The rental clears roughly 1.2x on rent against PITIA, so the purchase loan fits. The line’s payment is separate, so the full monthly picture includes both loans. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Reserves come from your own savings. Many DSCR files want around six months of PITIA, though conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Larger loans typically step up to about nine months. Borrowed money often cannot fill that bucket.
The strongest files clear both tests: enough equity for the line and enough rental coverage for the purchase loan.
Where the General Rule Breaks
A few edge cases change the answer.
Title in an LLC. Equity lines in this network can only be held by an individual borrower or a 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 name, subject to lender program eligibility. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead.
Converting a home to a rental. BiggerPockets describes opening the line while the home is still your primary residence, then moving out. That workaround is a practitioner tactic, not a guarantee. Your line’s terms and your lender’s occupancy language govern.
Property type. Eligible collateral includes single-family homes, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible. On the DSCR purchase side, manufactured homes, log homes, and barndominiums are not offered.
Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
Credit events. A bankruptcy needs four years of seasoning from discharge or dismissal. Investment files follow a seven-year path for foreclosure and four years for a deed-in-lieu, pre-foreclosure, or short sale.
Portfolio limits. A borrower is limited to three lines. An owner of more than 15 financed properties is not eligible.
Geography. These equity lines are brokered only in Lendmire’s 16 full-service states: Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia, and Washington. That is narrower than Lendmire’s DSCR footprint of 41 markets, including Washington, D.C. Some states also apply their own overlays. A Texas primary residence, for example, is a homestead and caps at 80% combined loan-to-value.
Self-employed borrowers. Business bank accounts need a 680 minimum for the deposit analysis. Because investment lines already floor at 700, bank statements are never the binding constraint there. Lendmire’s piece Best Bank Statement HELOC Program to Buy a Real Estate Investment covers that documentation path.
How Do You Choose Among the Options?
The best program depends on the property, your equity, your credit profile, and how much leverage you want to carry. A broker shops this across multiple wholesale lenders and matches the scenario to the program, rather than starting from one lender’s menu.
| Option | Best fit | Main catch |
|---|---|---|
| Line on primary home | Strong equity, 720+ credit, individual title | Your home backs the rental |
| Line on existing rental | Seasoned rental, 700+ credit, personal title | 70% CLTV and a $500,000 cap |
| DSCR cash-out refinance | Rental held in an LLC or with larger equity | About six months of seasoning |
On a standard rental, a DSCR cash-out refinance tops out around 75% LTV across most of the network. For short-term rentals, the cash-out ceiling is 70%. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000, the network generally holds to 30-year fixed structures.
Is this a toss-up? Sometimes. The cash-out refinance costs more up front and needs seasoning. The line is cheaper to open but puts a floating payment on top of the new mortgage. The honest answer hinges on how long you plan to carry the balance.
Common Mistakes
- Assuming the line replaces the DSCR loan. It doesn’t. You still need rental coverage, credit, and reserves on the purchase.
- Drawing without asking the purchase lender. Borrowed funds are accepted differently from program to program.
- Counting borrowed cash as reserves. It often will not count.
- Sizing to maximum equity. Since 75% of the line is drawn at closing, a bigger line means more interest on money you did not need.
- Ignoring the step-up. The interest-only draw ends. Repayment begins on a schedule you can see in advance.
- Using an LLC. The line cannot close in one.
Notice what a larger down payment can and cannot do. It lowers the purchase payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility.
Before You Decide

Frequently Asked Questions
Can I use a HELOC for the entire purchase price of a rental?
Technically yes, but it is rarely wise. You would be borrowing close to the property’s full value against your home, and the rental would have almost no equity cushion. Most investors use the line for the down payment and closing costs, then finance the rest with a DSCR purchase loan.
Does a HELOC down payment hurt my DSCR lender review?
Usually not directly, since DSCR purchase loans do not review your personal debt-to-income ratio. The question is whether the purchase lender accepts borrowed funds. Many accept them for the down payment and closing costs with documentation, but exclude them from reserves. Confirm before you draw.
Can an LLC hold a HELOC on a rental property?
No. Title must be held by an individual borrower or a revocable living trust. If the rental sits in an LLC, a DSCR cash-out refinance is the more realistic route, subject to lender program eligibility.
How much can I borrow on an investment property versus my primary home?
On an investment property, the network’s ceiling is 70% CLTV, up to a $500,000 line, with a 700 minimum credit score. On a primary residence, the ceiling reaches 90% CLTV at 720 or better, and lines can run up to $750,000. All figures are subject to lender guidelines and full file review.
What happens when the draw period ends?
On an investment line, the five-year interest-only draw ends and a 25-year fully amortizing repayment begins. Pricing floats the whole time and never converts to fixed. Plan your payoff or refinance before the step-up.
