The Quick Read: Getting approved means clearing two separate tests: the equity line, which looks at your credit, your debts, your income, and the equity left in the property, and the rental purchase loan, which looks at whether the new property’s rent covers its own payment. A line can fund the down payment, but it cannot lift the new loan past its own leverage, credit, and property rules. Every figure below is subject to lender guidelines and full file review.
- The line is judged on you and the property that secures it. The DSCR loan on the new rental is judged on that rental’s rent against its full payment.
- Leverage caps depend on occupancy. On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), while primary residences reach 90% only at a 720-or-better credit profile.
- Borrowed down-payment funds are commonly accepted with documentation, but they generally do not count toward reserves.
- The line payment stays out of the new property’s DSCR, but it still comes out of your bank account every month.
- Open the line before you need it, because the funds usually have to sit in your account before the purchase.
A HELOC looks simple from the outside: you borrow against equity you already own and use the cash to buy the next rental. The mechanics are simple. The qualification is where files stall. This walkthrough takes the process in order. It covers what the line is, how each lender looks at it, what structures exist, where the usual rules break, and what the decision looks like in practice.
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.
Key Terms Defined
HELOC (home equity line of credit): A revolving credit line secured by a property you own, which you can draw from, repay, and draw from again within a set window.
Equity: The property’s value minus what you still owe on it.
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the property’s value.
DSCR (debt service coverage ratio): Monthly rent divided by the monthly principal, interest, taxes, insurance, and HOA dues on the rental.
PITIA: Principal, interest, taxes, insurance, and association dues, which is the full monthly payment on a property.
DTI (debt-to-income ratio): Your monthly debt payments divided by your monthly income.
Seasoning: The time borrowed or deposited funds must sit in your account before a lender treats them as settled.
Reserves: Cash left over after closing that a lender counts as your cushion.
What Does It Take to Qualify for the Line Itself?
You qualify for the line on credit, debts, income, and equity. A wholesale lender in our network sets a maximum CLTV by credit tier, then checks that your debt-to-income ratio holds up with the new payment included.
Market surveys report that equity lines typically want a credit score near 620, a DTI of 43% or less, and 36% or less for the best offers, according to NerdWallet. Those are broad market ranges. The network programs run on their own terms. The credit floor is 600 on a primary residence, 640 on a second home, and 700 on an investment property. DTI tops out at 50%, drops to 45% for credit profiles from 600 to 679, and anything above 45% requires at least a 680.
One detail surprises people. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to use. Also, at least 75% of the line is drawn at closing. Size the line to the need, because you are not opening a large line and drawing a sliver.
Other file basics matter too:
- Credit report: The score comes from a single-bureau model keyed to the primary wage earner. The report can be no more than 90 days old at closing, and no rescores are allowed.
- Bankruptcy: It needs 4 years of seasoning from discharge or dismissal.
- Foreclosure history: On primary residences and second homes, one wholesale program seasons a foreclosure in 7 years and a deed-in-lieu, pre-foreclosure, or short sale in 4. The other declines that history entirely, whatever its age. Investment files follow the 7-and-4-year path.
- Exposure: A borrower is limited to three lines in total, and owning more than 15 financed properties is not eligible.
- Availability: These lines are brokered only 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.
How Much Can You Borrow? The Equity Math
The line equals the CLTV ceiling times the property’s value, minus what you owe on the first mortgage. The ceiling depends on occupancy and credit, so state your occupancy before you quote any number.
| Occupancy | Top CLTV | Credit pairing | Max line |
|---|---|---|---|
| Primary residence | 90% | 720+ only | $500,000 at 90% |
| Primary residence (larger line) | 75% | 700+ (720 on the longer-runway program) only | $750,000 at 75% |
| Second home | 90% | 720+ only | $500,000 |
| Investment property | 70% | 700+ minimum | $500,000 |
A primary residence can reach a $750,000 line, but only at 75% CLTV or lower. Lower credit tiers step the ceiling down. A 640 score on a primary residence, for example, caps at 80% CLTV. Any line above $500,000 is primary-residence only and requires a full appraisal. Lines at or below $500,000 ordinarily run an automated valuation, though a borrower may request a full appraisal in any case.
Consider a worked example, using percentages only. Say your primary home has a first mortgage at 55% of its value, and your credit profile is 700 or better, which supports 85% CLTV on a line up to $500,000. The line can reach 30% of the home’s value. At 25% down on the next rental, that supports a purchase worth about 120% of your home’s value. At 20% down, it supports about 150%. Closing costs shave those numbers. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Now run the same logic on a paid-down rental you already own. With the first mortgage at 50% of value, the 70% investment ceiling leaves a line of 20% of the property’s value. That funds a much smaller purchase. The investment ceiling is a real constraint, so the occupancy of the collateral changes the whole plan.
The older CFPB HELOC booklet illustrates the same arithmetic with a percentage of appraised value minus the mortgage balance. Its 75 percent figure is only an example, not a rule.
Which Property Should Secure the Line?
You have two routes: a line on your primary home, or a line on a rental you already own. The primary-home route is usually easier. It carries higher ceilings, and lenders are more comfortable with owner-occupied collateral. The White Coat Investor reports that investment-property HELOCs are harder to qualify for, and fewer lenders offer them.
The tradeoff is risk. If you secure the line with your home and then fall behind, you could lose it. The CFPB describes a HELOC as an open-end credit line you can borrow against repeatedly, with a draw period that could last 10 years and a repayment period often running 10 or 20 years. It also warns about losing your home. A line on a rental puts the rental at risk instead of your home, but it faces the tighter 70% CLTV and 700 minimum credit.
Title is the sharpest edge case. The network’s lines require the property to be held by an individual borrower or a 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 instead, subject to program terms.
Eligible collateral includes single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
How Does the Purchase Lender See the Borrowed Money?
The DSCR lender checks three things: where the cash came from, whether it counts as your money, and whether the rent covers the new payment. Across the programs we place files with, borrowed funds are commonly accepted for the down payment and closing costs with documentation. They generally do not count toward reserves.
That distinction trips up investors. A line can cover the down payment, but it does not build the cushion. Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around 6 months of PITIA. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about 9 months. If your plan spends every borrowed dollar on the down payment, check your own cash against that cushion before you apply.
Here are the typical purchase leverage figures on the DSCR side:
- Most purchase files land at 75% to 80% LTV on a standard rental, which means 20% to 25% down.
- Select programs reach 85% LTV on a purchase, which means 15% down, with roughly a 700+ score.
- Credit floors run from 620 in parts of the network, with most programs wanting around 660. A 700+ score unlocks the strongest leverage tiers.
- Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
For the full picture of how these loans work, see Lendmire’s complete DSCR loans guide.
A larger down payment lowers the new loan’s 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.
Where the HELOC Payment Shows Up (and Where It Does Not)
The line payment does not enter the new property’s DSCR, because that ratio looks only at the subject rental’s rent and PITIA. It does enter your life. After closing, you carry three obligations: the first mortgage, the line, and the new rental loan.
Two points to keep straight:
- The DSCR is not cash flow. Clearing 1.00 means rent covers PITIA. It does not account for repairs, vacancy, management, utilities, or capital expenses.
- DTI-based loans count the payment. If your next loan is reviewed around DTI rather than rental coverage, the line’s payment is counted. That does not apply to a DSCR purchase.
The payment also floats. During the draw period, the minimum payment usually covers only interest and rises when market conditions move, as NerdWallet notes. On the network lines, the pricing floats across both the draw and repayment periods and never converts to fixed. The draw structures on primary residences and second homes are:
| Structure | Draw period | Repayment period |
|---|---|---|
| Shorter runway | 3 years interest-only | 17 years amortizing |
| Longer runway | 5 years interest-only | 25 years amortizing |
Investment lines run the 5-year draw and 25-year repayment structure only. The line can sit in first or second lien position.
What Is the Right Order of Operations?
Open the line first, draw early, and apply for the rental loan last. Lenders may want drawn funds to season in your account, so a draw made the week of closing creates avoidable questions. We keep the seasoning period qualitative here, because it differs by lender and file.
Here is the sequence that works:
1. Check your equity and credit. Know your CLTV and which tier you fall in before you apply.
2. Pick the collateral. Decide between your home and a rental, using the title and ceiling rules above.
3. Open the line before you find the deal. A line you open mid-contract is a line that may not be ready.
4. Draw the funds and let them settle. Keep the draw in an account in your name, not scattered across transfers.
5. Get the DSCR purchase reviewed. Confirm the lender accepts borrowed funds and how it wants the source documented.
6. Close the purchase. The line funds the down payment, and the rent has to cover the new loan.
One risk deserves attention: the line can be frozen or reduced if the property value falls or your credit changes. Do not count on undrawn availability for a contract you have already signed. This is another reason the network structure requires most of the line to be drawn at closing.
Where the General Rule Breaks
A few cases change the plan:
- Paying off the line with a DSCR cash-out refinance. Some investors use a line for the down payment and renovation, then refinance with a DSCR cash-out loan once the property is rented. On a standard rental, that tops out around 75% LTV, with about 6 months of seasoning as the common expectation. A cash-out refinance replaces the first mortgage, while a line leaves it in place.
- Fully borrowed down payment. If every dollar of the down payment is borrowed, you are financing close to the whole purchase. The numbers need to hold under that load.
- Short-term rentals. If the next property is a short-term rental, DSCR leverage is lower than on a standard rental, and the program typically asks for a documented hosting history. Short-term rental rules vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.
- Ineligible properties. Manufactured homes, log homes, and barndominiums are not offered on the DSCR side either.
- Texas primary residences. A Texas primary residence is a homestead, which caps at 80% combined LTV. Second homes and investment properties follow the standard tables. A property listed for sale, or listed in the past 60 days, is ineligible in NC, PA, TN, TX, and WA. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
What Sinks the File?
Most failed files break in one of these ways:
- Counting borrowed money as reserves.
- Drawing too close to closing, so the funds have no history.
- Letting credit change between approval and closing, with new debt or late payments.
- Underestimating the payment stack, with the first mortgage, the line, and the new loan all due.
- Choosing an LLC-held rental as collateral without fixing the vesting.
- Sizing the line too large, then being unable to carry the draw required at closing.
Readiness Checklist
Run this before you apply. A “no” on any line tells you where to work first.
- Do you know the property’s value and your first mortgage balance?
- Does your CLTV leave room for a line at your occupancy’s ceiling?
- Is your credit at or above the floor for that occupancy?
- Is your DTI at or below 50%, with the new line’s interest-only payment included?
- Is the collateral held by you or a revocable living trust?
- Can the line’s draw plus your own cash cover the down payment and the reserves?
- Will the new rental’s rent cover its full PITIA, with room to spare?
Frequently Asked Questions
Can a HELOC cover the whole down payment?
It can cover the down payment and closing costs when the equity supports it, but that leaves reserves unfunded. Borrowed funds generally do not count as reserves. A fully borrowed down payment also means you are financing nearly the entire purchase, so the rent and your cash cushion need to carry that load.
Does the HELOC payment lower my DSCR?
No. The DSCR compares only the new rental’s rent to its PITIA, and the line’s payment sits outside that math. It still reduces your monthly cash, and on loans that qualify on DTI, it counts against you. Budget for it before you draw.
Can I use a line on a rental I own through an LLC?
Not directly. The network’s lines require title in an individual’s name or a revocable living trust, so an LLC-held rental needs a vesting change first, subject to program terms. A DSCR cash-out refinance is the other route.
How much credit do I need?
It depends on occupancy. The floor is 600 on a primary residence, 640 on a second home, and 700 on an investment property. Higher scores unlock higher ceilings, and 90% CLTV exists only at 720 or better on primary and second-home lines.
Should I open the line before I find the property?
Yes. Opening early lets you draw, season the funds, and know your actual numbers before you make an offer. Waiting until a contract is signed adds pressure the file does not need.
