The Quick Read: With no mortgage to subtract, a home equity line can reach the lender’s full combined-loan-to-value cap, and the cash becomes your rental down payment, so buying power is roughly the line divided by your down-payment percentage, before closing costs and reserves. A separate DSCR loan still has to approve the rental on its own merits.
- On Lendmire’s wholesale network, a line on a primary residence or second home reaches 90% combined loan-to-value only at a credit profile of 720 or better.
- On an investment property, a line caps at 70% combined loan-to-value and $500,000 total.
- A line above $500,000 is primary-residence only, caps at 75% combined loan-to-value, and needs a full appraisal.
- At 20% down on the rental, each 1.00 of line supports roughly 5.0 of purchase price before costs and reserves.
- Clearing 1.00 on the rental’s coverage ratio is not the same as positive cash flow, and the line’s payment sits on top of the rent check. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Key Terms Defined
HELOC: a home equity line of credit, an open-ended credit line secured by your home that you draw on as needed.
CLTV (combined loan-to-value): all loans secured by the home added together, divided by the home’s value.
DSCR loan: a business-purpose investor loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
PITIA: principal, interest, taxes, insurance, and any association dues, which together make up the rental’s monthly payment.
Reserves: liquid money a lender wants left over after closing, commonly counted in months of PITIA.
Draw period: the stretch when you can borrow from the line, usually paying interest only.
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.
What a Paid-Off Home Line Does (and Doesn’t Do)
A HELOC on a home you own free and clear supplies cash. That is all. It never buys the rental, and it never replaces the loan that does.
Two lenders make two separate decisions. The line lender looks at you and your home: value, credit, debt-to-income. The DSCR lender looks at the rental: its rent, its payment, its appraisal. Approval from one says nothing about the other.
Why does a paid-off home help? Because nothing gets subtracted. A home carrying a mortgage has part of its borrowing room already used. A paid-off home starts with the full cap available. Most of the time that makes it the cleanest collateral an investor owns.
Not free, though. The line puts a new lien on the home you live in. That tradeoff runs through everything below.
How Far Does the Line Go?
The ceiling depends on occupancy, and the network’s ceilings differ sharply. Across the wholesale partners Lendmire places files with, the top tier is reserved for primary-residence and second-home lines with a 720-or-better credit profile.
Lendmire places lines with two wholesale programs. One is a higher-leverage program. The other offers longer draw-and-repayment options, and this article calls it the longer-runway program. Figures below are typical guideline ranges, subject to lender guidelines and full file review. They are not commitments to lend.
| Collateral | Max CLTV | Notes |
|---|---|---|
| Primary residence, line up to $500,000 | Up to 90% | 90% only at 720+ credit |
| Primary residence, line above $500,000 | 75% | 700+ (720 on longer-runway); full appraisal |
| Second home | Up to 90% | 90% only at 720+; 640 minimum |
| Investment property | 70% | 700 minimum; $500,000 total cap |
Lines run from $25,000 to $750,000. Lower credit tiers carry lower ceilings than the top figure shown. Many homes will hit the line-size cap before the CLTV cap, so a high-value house does not scale the line without limit.
On this network, 90% on a primary residence or second home requires 720 or better, and an investment line stops at 70%.
From Line Size to Rental Purchasing Power
The conversion is simple division. Cash from the line funds your down payment, so purchase price is roughly the line divided by the down-payment percentage. Most DSCR purchases land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV (15% down) with roughly a 700-plus score. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Here is the arithmetic in ratios, before closing costs and reserves.
| Down payment | Price per 1.00 of line | Per 1.00 of home value at 90% CLTV | Per 1.00 of home value at 75% CLTV |
|---|---|---|---|
| 25% | 4.0 | 3.6 | 3.0 |
| 20% | 5.0 | 4.5 | 3.75 |
| 15% | 6.7 | 6.0 | 5.0 |
Read it this way: a paid-off primary home at 90% CLTV, with 20% down on the rental, supports roughly 4.5 times the home’s value in rental purchase price. Closing costs and reserves come out of the same pot. Assume, as a modeled input, that one-fifth of the line goes to those costs. The 4.5 then shrinks to roughly 3.6. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Two limits cut that number further. The line-size cap may bind first. And lenders typically want at least 75% of the line drawn at closing, so you start paying on a large balance immediately. The site’s illustrative calculator can do the unit conversion for your numbers.
The Sizing Formula, Step by Step
The method is the same one lenders have used for decades. The CFPB’s HELOC booklet shows it: take the appraised value, multiply by the lender’s percentage, then subtract what you still owe. Its worked example follows exactly those steps.
For a paid-off home, the last step is zero. Available line equals value times the maximum CLTV. Then the other filters apply: credit profile, a debt-to-income ceiling of 50% (45% for scores from 600 to 679), and qualification on the interest-only payment at the maximum draw.
Valuation is usually light. Lines at or below $500,000 ordinarily run on an automated valuation with no traditional appraisal, though a higher CLTV may require a second valuation. Anything above $500,000 needs a full appraisal. A borrower can also request a full appraisal in any case.
Two Approvals, Two Underwriters
The line lender asks about you. The DSCR lender asks about the rental.
| Question | Line lender | DSCR lender |
|---|---|---|
| Who is underwritten? | You | The property’s income |
| Key number | CLTV and DTI | Rent vs. PITIA |
| Collateral | Your home | The rental |
| Title | Individual or revocable trust | LLC possible, per program terms |
Title is the sharpest difference. The line needs the home held by you personally or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on the line. A home already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead. The rental itself can sit in an LLC, subject to lender program eligibility.
Credit matters on both sides. The line has a 600 program floor. A DSCR purchase files best around 660, with a 620 floor in parts of the network and 700-plus unlocking the strongest leverage tiers. A single missed standard on either side stops the plan.
Step by Step: How the Sequence Works
1. Ask the DSCR side first. Programs differ on borrowed down-payment funds. Some accept documented line proceeds. Some want part of the down payment to be your own seasoned cash. A few want it unborrowed. A plan funded 100% by borrowing can fail on that rule alone.
2. Qualify for and open the line. Do this before going under contract, because lenders can freeze or reduce lines.
3. Draw and document. Keep the closing papers, the draw confirmation, and statements showing the cash landing in your account.
4. Underwrite the rental. The DSCR lender works from the lease or a market-rent exhibit, the appraisal, insurance, and entity documents. Appraisers use a rent schedule form for single-family homes and a different operating-income form for two-to-four units.
5. Close with the paper trail intact.
The line’s payment generally sits outside the coverage ratio, because DSCR compares the subject property’s rent to its own PITIA. That is a real advantage over a conventional loan, where a new line payment would enter your debt-to-income math. Lender practices vary, though, and some still glance at overall debt.
What You’re Risking
Start with the definition. The CFPB describes a HELOC as an open-end line you can borrow against repeatedly. It also warns that payments can rise sharply when repayment begins and that missed payments can cost you the home.
Pricing on these lines floats through both the draw and repayment periods and never converts to fixed, and the payment steps up when the draw ends. Investment-property lines run a five-year draw and 25-year repayment. Primary and second-home lines offer a 3-year-draw and a 5-year-draw structure. Tennessee shortens both. Either way, plan for the step-up.
Then there is leverage. Borrow the down payment and finance the rest at 75% to 80% LTV, and you are financing close to 100% of the purchase across two liens. If rents soften, you owe two payments from one rent check. Benzinga makes the same point in plain terms: you carry the new mortgage and the line together. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
A DSCR above 1.00 is not positive cash flow. Coverage compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex all sit outside it, and so does the line’s payment. Where a property falls below 1.00, a separate select-lender path exists in the network, with leverage and terms adjusted.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
A practitioner observation: the files that stall are rarely about equity. They stall on sequencing. The line is opened, the cash is drawn, and only then does the DSCR lender say part of it must be seasoned or unborrowed. Asking first costs nothing.
Stress Tests Worth Running
Run three versions of your plan before you open anything.
Vacancy. Assume the rental sits empty for part of a year. Can you cover both payments from savings? Reserves on the DSCR side commonly run around 6 months of PITIA, and they vary by lender, leverage, loan size, and transaction type. Loans above $1,500,000 typically step up toward 9 months. Borrowed money and reserves are separate questions, and many programs will not count borrowed funds toward reserves.
Payment step-up. Model the line at the end of the draw period, with the balance amortizing. That is the number to survive, not the interest-only one.
Exit. Decide how the line gets repaid. Common routes are paying it down from rent and savings, or later refinancing the rental. Cash-out refinances on standard rentals top out around 75% LTV across most of the network, and about 6 months of seasoning is the usual expectation. Check any prepayment penalty on the DSCR loan first, because it can interfere with that exit. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Alternatives for Rental Buyers
| Option | Collateral | Main constraint |
|---|---|---|
| Line on paid-off home | Your residence | Lien on your home |
| Cash-out on existing rental | That rental | ~75% LTV; ~6 months seasoning |
| Line on a rental | A rental | 70% CLTV; $500,000 cap |
| Saved cash | None | Opportunity cost |

Is This Right for You?
Use this as a go or no-go checklist.
- You have equity at the CLTV cap for your credit tier and occupancy.
- Your credit clears both sides: 600-plus for the line, and around 660 or better for most DSCR programs.
- Your DSCR lender accepts documented line proceeds, or you hold enough of your own seasoned cash.
- The rental’s coverage clears the program’s floor with room left over.
- You could carry both payments through a vacancy.
- You have a written plan to repay the line.
If you own more than 15 financed properties, you are not eligible for the line. A borrower is also limited to three lines. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use or agricultural zoning are not eligible collateral for the line. DSCR purchases do not offer manufactured homes, log homes, or barndominiums.
One availability point. Lendmire arranges lines through select wholesale partners in 16 full-service states, a narrower set than its DSCR footprint of 41 markets, including Washington, D.C.
Frequently Asked Questions
How much rental can a paid-off home line buy?
Roughly the line divided by your down-payment percentage, before costs and reserves. At 90% CLTV and 20% down, that is about 4.5 times the home’s value. At 75% CLTV, it is about 3.75 times. The line-size cap and the share of the line you must draw can pull that lower. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Will a DSCR lender accept HELOC money as my down payment?
Often, with documentation, but acceptance is program-specific. Some programs require part of the down payment to be your own seasoned cash, and others want it unborrowed. Confirm before you draw.
Does the line’s payment count against my coverage ratio?
Generally not. The ratio compares the rental’s rent to its own PITIA. Some lenders still review overall debt, and the line lender reviews your file on the interest-only payment at the maximum draw.
Can my LLC take out the line?
No. The home must be held by you or by a revocable living trust. A rental inside an LLC can still take a DSCR purchase loan, subject to lender program eligibility.
Does line approval mean my rental loan is approved?
No. They are independent decisions by independent lenders, each subject to its own guidelines. Neither is a commitment to lend.
