The Quick Read: The best HELOC program for buying a rental depends on your situation: which property secures the line, how much cash the deal needs, how much combined leverage that property can carry, and whether your purchase lender accepts borrowed down payment funds. A HELOC (home equity line of credit) does not buy the rental. It supplies cash for the down payment and closing costs, while a separate loan, usually a DSCR loan, finances the property. Lendmire is a mortgage broker, not a lender. It shops this scenario across a network of wholesale lenders, and every figure below is subject to lender guidelines and full file review.
- A line on your primary home reaches higher leverage than a line on a rental. On this network, an investment-property line tops out at 70% CLTV (combined loan-to-value, explained below) and $500,000.
- An investment-property line needs a 700 credit score at minimum, and an LLC cannot hold title to the pledged property.
- Your DSCR purchase lender decides separately whether borrowed funds count as down payment. Get that answer before you draw.
- Clearing a 1.00 coverage ratio on the DSCR loan does not make the deal cash-flow positive, because the line payment comes out of the same rent.
What Does a HELOC Actually Do in a Rental Deal?
A HELOC is a cash source, not an acquisition loan. You borrow against equity in a property you already own, then use the money to fund the cash side of a purchase. The purchase loan covers the rest.
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.
Investors use these lines in two ways, as RentalRealEstate.com lays out. The most common is a line on the primary residence, with proceeds funding the investment purchase. The other is a line directly on an existing rental. Fewer lenders offer that second route, and the requirements are stricter.
The reason investors reach for a line is simple. Most DSCR purchases land at 75%-80% LTV (loan-to-value, the loan divided by the property’s value), which means 20%-25% down. Even then, you need cash for the down payment, closing costs, and reserves. A line fills that gap if you have the equity. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
One sequencing fact trips people up. You cannot open a line against a property you have not bought. The collateral must be a home or rental you already own, so the line comes first and the contract second.
Key Terms Defined
CLTV (combined loan-to-value): Every loan secured by the property, added together, divided by the property’s value. A first mortgage plus a HELOC both count.
Draw period: The stretch when you can borrow from the line and pay interest only.
Repayment period: The stretch after the draw ends, when you can no longer borrow and the balance amortizes.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s monthly payment: principal, interest, taxes, insurance, and any HOA dues. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
PITIA: Principal, interest, taxes, insurance, and association dues. It is the payment the DSCR ratio tests.
Source of funds: The paper trail showing where your down payment came from.
How Underwriting Treats the Line, Step by Step
The line is underwritten to you, not to the rental. That is the biggest difference from the DSCR loan you will use for the purchase.
1. The lender sizes the equity. It adds every lien on the pledged property and divides by value to get CLTV. A line ordinarily sets its limit by taking a percentage of the home’s value and subtracting what you owe, a method the federal consumer-finance regulator’s HELOC booklet walks through.
2. Your credit is pulled. Across this network the investment floor is 700, and credit above that does not buy more leverage. More on that below.
3. Your debt load is tested. The maximum DTI (debt-to-income ratio) is 50%, and 45% for credit profiles from 600 to 679. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
4. Value is established. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal, though a higher CLTV can trigger a secondary valuation. You can also request a full appraisal.
5. You draw. At least 75% of the line is drawn at closing. That surprises people, so plan for it.
6. You move the money cleanly. Park the draw in a dedicated account, then wire it to title. Clean paper helps the purchase lender later.
Then the DSCR loan underwrites the rental itself. Your personal DTI generally is not part of that review. The line payment sits outside the ratio, but it still comes out of your real cash.
Which Structure Is Best? A Side-by-Side Look
No single structure wins. Here is how the main options compare on this network.
| Factor | Line on primary home | Line on a rental | DSCR cash-out refinance |
|---|---|---|---|
| Max CLTV / LTV | Up to 90% at 720+ | 70% | Around 70% LTV |
| Minimum credit | 600 floor, varies | 700 | Varies by program |
| Qualified on | You personally | You personally | Property rent |
| LLC title allowed | No | No | Subject to program terms |
| Main risk | Your home is at stake | Tighter limits | Replaces your first mortgage |
A DSCR cash-out refinance replaces your existing first mortgage with a new, larger loan. A line keeps the first mortgage in place and adds a second layer. If your current first mortgage is one you want to keep, that points toward the line. If you want a single loan and a lump sum, it points toward the refinance. Cash-out refinance on a standard rental tops out around 70% LTV, with about 6 months of seasoning as the common expectation. Seasoning is the waiting period between a purchase or refinance and the next transaction. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
What the Network Looks Like for an Investment Line
These are the verified figures for a line secured by an investment property. They are guidelines, not promises.
- Leverage: 70% CLTV, and nothing above it for investment collateral.
- Credit: 700 minimum. A 720 and a 700 both reach the same 70% CLTV, so higher credit buys eligibility rather than extra leverage.
- Line size: Up to $500,000.
- Structure: A 5-year interest-only draw, then a 25-year fully amortizing repayment. Pricing floats through both periods and never converts to fixed.
- Valuation: Because the line caps at $500,000, it falls in the automated-valuation lane and commonly closes without a traditional appraisal.
- Property types: Single-family, 2-4 units, PUD, townhome, and condominium including non-warrantable. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible.
Compare that with the primary home. A primary-residence line reaches up to 90% CLTV, and that top tier exists only at a 720-or-better credit profile.
Primary-home lines range from $25,000 to $750,000. Two draw structures exist there: a 3-year interest-only draw with a 17-year repayment, and a 5-year draw with a 25-year repayment. A line above $500,000 is primary-residence only. It requires a 700 credit profile or better (720 on the 5-year draw structure), caps at 75% CLTV, and requires a full appraisal.
Lendmire’s HELOC programs run in 16 full-service states, which is narrower than its 41-market DSCR footprint of 40 states plus Washington, D.C.
Where the General Rule Breaks
Some situations change the answer.
Title in an LLC. Fee simple or leasehold title must sit with you personally or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. That is the sharpest difference from a DSCR loan, which can close in an LLC subject to lender program eligibility. If a rental is already deeded to an LLC, you need a vesting change or a DSCR cash-out instead.
Exposure limits. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on one wholesale program and $750,000 on the other. An owner of more than 15 financed properties is not eligible. One line rarely covers several purchases anyway.
Recently listed property. In some states, a property listed for sale, or listed within the past 60 days, is ineligible.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by occupancy. On investment files, a foreclosure seasons for 7 years and a deed-in-lieu, pre-foreclosure, or short sale for 4.
A fully borrowed down payment. If a line funds everything, you are financing close to 100% of the purchase. You then carry three obligations: the first mortgage, the line, and the new rental loan. Tight rent leaves no cushion.
Recent seasoning on the rental. A rental bought or refinanced recently may not be ready to pledge. A cash-out refinance counts as a fresh transaction, so plan the order of operations.
Will the DSCR Lender Accept Borrowed Funds?
Your HELOC lender’s approval settles nothing for the purchase. The DSCR lender decides on its own whether borrowed money counts. Across our wholesale network, the pattern looks like this:
- Many programs accept documented line draws for the down payment or closing costs.
- Borrowed funds are often excluded from reserves. Down payment, closing costs, and reserves are three separate buckets.
- Some programs cap the borrowed share.
- Some require a slice of unborrowed funds sitting in your account.
- Some want the draw to season in your account for a stretch before the contract.
Reserves vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about 9 months. Ask for the borrowed-funds answer in writing before you draw a dollar.
If you want the full picture of how the purchase loan itself works, the complete DSCR loans guide covers it.
The Cash-Flow Trap
A DSCR above 1.00 is not positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. So does your line payment.
Say you buy with the line and clear 1.10 on the purchase loan. Rent covers the property’s payment with a sliver to spare. Now add an interest-only line payment that floats. The sliver is gone, and the shortfall comes from your pocket. Not ideal.
The 1.00 level is where select programs start, not a standard. Stronger coverage opens better pricing and leverage. Coverage below 1.00 is a separate path, available through select lenders in the network with leverage and terms adjusted. If your deal only works at thin coverage, the line makes it thinner.
Picking the Program: Three Situations
Run the logic on three borrowers.
The owner with a primary home and meaningful equity. Picture an investor who owns a primary residence with a modest first mortgage. If the credit profile is 720 or better, that home can carry the highest leverage on this network. The line funds the 20%-25% down on a DSCR purchase. This is the usual first move. The risk is that the home secures the debt. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
The owner with a paid-off rental in personal name. Consider an investor with a free-and-clear single-family rental, a 700+ score, and the title in their own name. The rental can secure a line up to 70% CLTV and $500,000. The home stays out of the deal. Leverage is tighter, and fewer lenders will touch rental collateral, but that is where a broker that shops several wholesale lenders earns its keep.
The owner whose rentals sit in LLCs. Say an investor holds everything in LLCs and wants cash for the next purchase. A line is off the table for those properties. A DSCR cash-out refinance, which is reviewed on rental coverage, is the usual alternative, or a primary home that is not in an LLC can carry the line.
Which is best? Honestly, a toss-up in some cases. The home line wins on leverage, and the rental line wins on keeping the residence out of the risk pool. The right choice depends on how much cash you need and how much risk you will carry.
When a HELOC Is the Wrong Tool
Skip the line in these cases.
- Your margin is thin. Floating pricing on a thin-coverage rental is a bad pairing.
- You need fixed, predictable payments. The line floats through both the draw and repayment periods and never converts to fixed.
- You are not confident you can carry it. The CFPB warns that falling behind on an open-end line against your home could cost you the home.
- You plan to sell soon. A line is generally repaid in full when the pledged home sells, so it complicates a near-term sale.
- You need money for several deals. One line rarely stretches across multiple purchases.
The CFPB also notes that after the draw period ends, you can no longer borrow and enter repayment. The balance then has to amortize, which changes your cash needs. Plan for that date before you open the line.
What to Prepare Before You Ask
A short checklist saves time and surprises.
- Current mortgage statements and a rough value on the property that would secure the line.
- A credit report within the window, since the report must be no more than 90 days old at closing.
- A written answer from your DSCR lender on borrowed funds.
- A plan for the 75% draw at closing, including where the money sits.
- A view of your cash flow with the line payment included.
Frequently Asked Questions
Can I use my home’s equity to buy a rental?
Yes, if the lender and your purchase lender both accept it. A line on your primary home can reach up to 90% CLTV at a 720-or-better credit profile on this network. Your DSCR purchase lender still has to accept the draw as down payment funds, so confirm that first.
Can the rental itself secure the line?
Yes, with tighter limits. An investment-property line caps at 70% CLTV and $500,000, and requires a 700 credit score. Title must be in your name or a revocable living trust, and fewer lenders offer this structure. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Can an LLC hold the line?
No. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A DSCR loan can close in an LLC, subject to program terms, so investors with entity-held rentals often use a DSCR cash-out instead.
Can a HELOC buy the whole property?
Technically a fully borrowed down payment means financing close to 100% of the purchase. That stacks three obligations and leaves little room if rent dips. Keeping some of the cash unborrowed gives you more room.
What are the biggest risks?
Your pledged property is at stake, pricing floats, and the line payment sits outside the DSCR ratio. Clearing the ratio does not guarantee positive cash flow. Stress the deal with the line payment included before you commit.
