The Quick Read: Homeowners can fund a rental purchase with a home equity line, but two separate approvals decide whether it works: the line itself, which turns on combined loan-to-value, credit, debt-to-income, and who holds title, and the rental’s purchase loan, whose lender decides whether borrowed money counts toward the down payment. Combined loan-to-value (CLTV) means every loan secured by the home, added together and divided by its value. Through Lendmire’s wholesale network, a line secured by an investment property tops out at 70% CLTV, needs a 700 credit profile, and caps at $500,000, subject to lender guidelines.
- A line on your primary home and a line on an existing rental follow different rules, and the investment version is stricter.
- The line is a loan against the property that secures it. It does not replace the rental’s own purchase financing.
- DSCR purchase lenders differ on borrowed down payments: some accept them, some cap the share, and some want part of the money unborrowed.
- Borrowed funds are commonly left out of reserves, so reserves usually need to come from your own cash.
- Clearing the rental’s coverage test does not mean the deal cash-flows after the line payment.
Two Loans, Not One
The “requirements” for this strategy come from two lenders. The first lender approves a home equity line of credit (HELOC) on a property you already own. The second lender approves the purchase loan on the rental. Most surprises come from the second lender, not the first.
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.
A HELOC is a revolving line secured by a property. You draw cash, park it in your own account, and use it toward the purchase. To the purchase lender, that draw is borrowed money. How the lender treats it decides how much of your down payment the line can actually cover.
A DSCR loan is the usual purchase loan for this audience. DSCR stands for debt service coverage ratio, which compares a rental’s income to its own monthly payment. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s complete DSCR loans guide covers the full mechanics.
Which Property Secures the Line?
The first fork is collateral. You can borrow against your primary residence, or against a rental you already own. The same borrower can face very different terms on each.
| Factor | Line on primary home | Line on an investment property |
|---|---|---|
| Max CLTV | Up to 90%, only at 720+ credit | 70% |
| Credit floor | 600 program floor | 700, with no tier below |
| Max line | $750,000 | $500,000 |
| Draw structure | Two options | 5-year draw, 25-year repayment |
| Valuation | Automated up to $500,000 | Automated, usually no appraisal |
Both columns are subject to lender guidelines and full file review. Lower credit tiers on a primary home sit below the 90% ceiling.
The investment column is tighter on every line. Credit above 700 buys eligibility, not extra leverage, because 720 and 700 both reach the same 70% ceiling. That is the sharpest difference between the two columns.
Risk differs too. A line on your home puts your home on the hook for a rental purchase. Lenders and investors tend to treat investment-collateral lines as riskier, which is why Benzinga’s overview of HELOCs on investment properties lists foreclosure risk on the securing property and added debt load among the downsides.
What Investment Property HELOC Requirements Look Like for Homeowners
The network’s requirements cover leverage, credit, income, title, and property type. Here they are in order.
Leverage. On an investment property, the ceiling is 70% CLTV. On a primary residence or second home, the ceiling reaches 90% CLTV only at a 720-or-better credit profile. Market-wide figures for equity lines vary by bank, so use the network figure for the occupancy you are borrowing against.
Line size. Lines run from $25,000 to $750,000. Anything above $500,000 is primary-residence only. It requires a credit profile of 700 or better (720 on the longer-runway program, introduced below), caps at 75% CLTV, and requires a full appraisal.
Credit. The program floor is 600, but an investment line starts at 700. The score model keys to the primary wage earner. The credit report can be no more than 90 days old at closing, and rescores are not offered.
Income. Maximum debt-to-income is 50%. It drops to 45% for credit profiles from 600 to 679, and a ratio above 45% needs a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw. That means a large line is tested at its full size, even if you plan to draw less.
Structure. Lendmire places lines through two wholesale programs. The higher-leverage program reaches higher combined leverage. The longer-runway program offers a longer draw-and-repayment structure on primary residences and second homes. On primary homes and second homes, one structure pairs a 3-year interest-only draw with a 17-year repayment, and the other pairs a 5-year draw with a 25-year repayment. Investment lines use the 5-year draw and 25-year repayment structure only.
At least 75% of the line is drawn at closing on both programs. So this is not a line you open and leave untouched. Pricing floats during the draw and repayment periods and never converts to fixed. After closing, the minimum subsequent draw on the longer-runway program is $1,000, except in Texas, where it is $4,000.
Valuation. An investment line is capped at $500,000, so it always lands in the automated-valuation lane. It commonly closes with no traditional appraisal, though you can request a full one.
Title. The individual borrower or a revocable living trust must hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If your existing rental sits in an LLC, the line is off the table until you change the vesting, or you use a DSCR cash-out refinance instead.
Property type. Single-family homes, 2-4 units, PUDs, townhomes, and condominiums (including non-warrantable) are eligible. Modular factory-built homes are eligible on the longer-runway program only, and 2-4 units need a 640 minimum there. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
Exposure. A borrower can hold three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. Owning more than 15 financed properties makes you ineligible.
Availability. Lendmire arranges these lines in 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 DSCR footprint.
Credit history standards also vary by program. The longer-runway program wants two tradelines seasoned 12 months, or one seasoned 24 months. A bankruptcy needs 4 years of seasoning from discharge or dismissal on both programs. Investment files with foreclosure history follow a 7-year path for a foreclosure and a 4-year path for a deed-in-lieu, pre-foreclosure, or short sale.
How Does the Purchase Lender Treat HELOC Money?
Treatment splits three ways across the network. Some DSCR purchase programs accept documented borrowed funds as down payment. Some cap the borrowed share. Some want part of the down payment to be unborrowed cash.
Several rules hold across most programs:
- Borrowed funds are commonly excluded from reserves. Reserves are the months of payments a lender wants you to keep on hand after closing.
- Unsecured borrowing, such as credit card advances, is generally not an acceptable source.
- A zero-down DSCR loan does not exist on the target property. The HELOC only changes where the down payment comes from.
Typical DSCR purchase terms look like this, subject to lender guidelines:
- Purchase leverage: most files land at 75%-80% LTV, meaning 20%-25% down. Select programs reach 85% LTV (15% down) with roughly a 700+ score.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
- Reserves: commonly around 6 months of PITIA, which means principal, interest, taxes, insurance, and association dues. They vary by lender, leverage, loan size, and transaction type.
The coverage ratio counts only the purchase loan’s payment. The line’s payment typically does not enter the ratio. Do not read that as permission to ignore it. You still have to pay the line from real cash flow.
DSCR also compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the math. Clearing 1.00 is not the same as positive cash flow.
A larger down payment lowers the monthly payment and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Step by Step: From Line to Closing
Order matters here. A common mistake is opening the line before checking the purchase lender’s rule on borrowed money.
1. Ask the purchase lender first. Confirm whether borrowed funds can count toward the down payment, and how much.
2. Size the line from equity. Add your first mortgage balance and the line, then divide by value. That total must stay under the ceiling for the occupancy.
3. Open the line before you contract. The line must close and be drawn before the purchase.
4. Draw and park the cash. Move it into your own account. Keep the deposit visible.
5. Document the paper trail. Expect to provide the line agreement, the draw statement, and the matching bank deposit.
6. Run the purchase file. The new property’s rent is tested against its own payment, with credit, reserves, and property eligibility reviewed as usual.
7. Plan the exit. Decide before closing how you will pay down the line.
A Worked Example in Percentages
Say you own a rental with a first mortgage equal to 45% of its value. Your credit is 700 or better, and the title is in your own name. An investment line tops out at 70% CLTV, so the line can sit in the gap of up to 25% of that rental’s value. The $500,000 line cap also applies, so the lower of the two limits governs.
Now say you want to buy a new rental on a 20% down purchase, at 80% LTV. If the line funds that whole 20%, you are financing close to 100% of the new property. The rental carries the purchase loan, and your other property carries the line. Reserves still have to come from cash that is not borrowed. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
The new rental might clear 1.2x on the purchase loan alone. After the line’s payment, its cash flow could be thin or even negative. An investor discussion on BiggerPockets frames the same test: the rent has to carry both the line payment and the loan payment.
That is why the investor decision has two gates. The first is whether the equity and credit fit the line. The second is whether the rental works after both payments.
Where the General Rule Breaks
The home you are about to sell. A line cannot sit on the house you are about to sell. It has to close and be drawn before the purchase.
LLC-held rentals. Because an LLC cannot hold title, a property deeded to one needs a vesting change or a DSCR cash-out refinance. Where a program allows LLC borrowers, that is subject to program terms.
Bank-statement approvals. A line approved on deposit history rather than traditional income documentation is still a separate loan with a separate approval from the DSCR purchase. It is reviewed on documented income under the applicable program, subject to lender guidelines. On an investment line, the 700 credit floor and the income qualification are separate tests, so clearing the credit floor does not settle whether the bank-statement income qualifies.
Multi-property packages. A package lender may refuse borrowed funds as down payment. Ten down payments can also exceed what a single line funds.
Excluded property types. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered through these programs. A rental of that type needs a different route than a HELOC-and-DSCR plan.
Short-term rentals. A short-term rental purchase has its own rules. Purchase leverage tops out at 75% LTV, and the borrower typically needs a 640+ score and about 12 months of hosting history. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Stress-Test Before You Draw
Variable pricing is the first risk. The CFPB’s HELOC explainer notes that HELOCs usually carry variable pricing, so payments can change from month to month. It also says the draw period could last 10 years, as an example. The network’s investment line runs a 5-year draw followed by a 25-year repayment.
Federal law requires a ceiling on how much variable pricing can increase over a line’s life, according to the CFPB’s consumer booklet on HELOCs. The booklet also notes that lenders weigh your ability to repay when setting the limit. A ceiling limits the worst case, but it does not remove it.
Run three tests before you draw:
- Both payments. Does rent cover the purchase loan payment and the line payment, with vacancy and repairs added?
- Payment reset. What happens when the interest-only draw period ends and the payment starts including principal?
- Downturn. If values fall, are you underwater on the rental, and maybe on the securing property too?
Exit planning deserves real attention. An investor discussion of HELOCs for a first rental argues the strategy is workable only with a reliable way to repay within a year or two. It also doubts that a cash-out refinance on the new property will retire the line unless equity is forced into the deal.
The experienced approach on files like this is to treat the line as a bridge with a repayment plan, not as permanent financing. Keep the first mortgage in place, or replace it, only after comparing the full cost of each path.
HELOC, Cash-Out, or DSCR Purchase?
| Factor | HELOC | DSCR cash-out refinance | DSCR purchase loan |
|---|---|---|---|
| What it does | Lends against existing equity | Replaces a loan, pulls equity | Finances the new rental |
| Reviewed on | Credit, DTI, equity | Property rent, credit | Property rent, credit |
| Typical leverage cap | 70% CLTV on investment | Around 75% LTV | 75%-80% LTV |
| Payment structure | Variable, never fixed | Fixed 30-year spine | Fixed 30-year spine |
A DSCR refinance can swap an existing first mortgage for new financing and does not depend on personal income. Cash-out refinance tops out around 75% LTV across most of the network, with about 6 months of seasoning commonly expected.
Who This Strategy Fits
A HELOC down payment tends to fit borrowers who:
- Hold meaningful equity in a primary home or a rental titled in their own name.
- Have a 700 or better credit profile, and debt-to-income at or below 50%.
- Have unborrowed cash for reserves.
- Can show rent covering both payments, plus a plan to pay the line down.
It tends to fit poorly when the only cushion is the line itself, or when the target rental is a property type outside the programs.
Key Terms Defined
HELOC: a revolving line of credit secured by a property you own, drawn as needed during a set draw period.
CLTV: combined loan-to-value, meaning all loans secured by the property added together and divided by its value.
Draw period: the stretch when you can borrow from the line, usually paying interest only.
Repayment period: the stretch after the draw period when you pay principal and interest until the balance is gone.
DSCR: debt service coverage ratio, the rental’s income divided by its own monthly payment.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly housing payment.
Reserves: the months of payments a lender wants you to keep in liquid funds after closing.
Vesting: the way title is held, such as in your own name or in a revocable trust.
Frequently Asked Questions
Can I use a HELOC as the entire down payment on a rental?
Sometimes, but it depends on the purchase lender. Some DSCR programs accept documented borrowed funds, some cap the borrowed share, and some want part of the down payment unborrowed. Reserves usually have to come from your own cash, since borrowed funds are commonly excluded.
What is the maximum CLTV on an investment property line?
The ceiling is 70% CLTV on an investment property, whether your credit is 700 or 720. The line maxes out at $500,000. Primary-residence lines can reach 90% CLTV, but only at a 720 or better credit profile.
Does the HELOC payment count in my DSCR?
Typically not. The coverage ratio counts only the purchase loan’s payment against the new property’s rent. Your cash flow still has to absorb the line’s payment, so test both payments together.
Can an LLC hold the line?
No. Only the individual borrower or a revocable living trust can hold title for these lines. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance instead.
Is an appraisal required?
Not usually on an investment line. Because the line caps at $500,000, it ordinarily runs automated valuation, though a higher CLTV may require a secondary valuation. A full appraisal is required above $500,000, and you can always request one.
