The Quick Read: A home equity line lets a rental owner keep an existing mortgage in place while borrowing against equity to fund the next purchase or to retire a different loan, and it works best when the owner has real equity, strong credit, and rent that covers every payment layered on top.
- An investment-property line through Lendmire’s network tops out at 70% CLTV and $500,000, with a 700 credit minimum, subject to lender guidelines.
- The line is underwritten on the borrower’s credit, income, and equity, not on the rental’s coverage ratio.
- A DSCR loan on the next property looks at that property’s rent against its own payment, so the line’s payment generally stays outside the ratio.
- Clearing 1.00 on coverage does not mean the deal cash flows, because the line payment, vacancy, and repairs sit outside the calculation.
The phrase can mean two different moves. One is drawing on a line to fund the down payment on the next rental. The other is drawing on one property to pay down or pay off the mortgage on another. Both rest on the same mechanics, and both carry the same trap: equity is borrowed, not free. This guide walks through how the line works, how underwriting treats it, what structures exist, and where the rules break.
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 Are the Two Ways Owners Use a Line to Invest?
The first use is acquisition money. An owner opens a line on a primary home or an existing rental, draws what the deal needs, and uses the cash toward the down payment and closing costs on a new rental. The first mortgage on the funding property stays untouched.
The second use is restructuring. An owner draws on property A to pay down or retire the mortgage on property B. That swaps one lien for another, and it changes the shape of the debt. A fixed loan on B becomes a floating line on A, and the risk moves to whichever property secures the line.
The right choice depends on the goal. If the goal is a new asset, the line is a funding source. If the goal is lowering a balance on an older loan, the line is a swap, and the swap needs a reason beyond convenience.
How Does a Home Equity Line Work Before It Touches a Rental?
A home equity line is a revolving credit line secured by the property. The owner borrows up to a limit, repays, and borrows again during the draw period. Interest runs only on what has been drawn.
Sizing follows one formula. Take the property’s value, multiply it by the lender’s combined loan-to-value cap, and subtract every lien already on the property. What remains is the possible line. The federal consumer-finance regulator’s HELOC booklet walks through this exact calculation using a 75% cap and a $100,000 home as its illustration.
Combined loan-to-value, or CLTV, counts the first mortgage and the new line together. That is why a low first mortgage matters. The less of the value already borrowed, the more room the line has.
Lending against a rental is harder than lending against a primary home. NerdWallet notes that the lender pool is smaller and that borrowers cannot draw as much as against an owner-occupied home. Many large retail lenders skip rental lines altogether.
How Does Underwriting Treat the Line, Step by Step?
Underwriting for a line on a rental starts with the person, then the property, then the structure. Here is the order a lender’s review typically follows.
1. Credit. The lender pulls a credit report keyed to the primary wage earner. On an investment property in Lendmire’s network, 700 is a hard floor. There is no lower tier.
2. Income and debt. The lender compares total monthly debts to income. The network’s maximum is 50%, and the lender qualifies the borrower on the interest-only payment calculated on the maximum draw. A line sized larger than needed can therefore hurt the file even if never fully drawn.
3. Equity. The lender applies the CLTV cap against current value. On an investment property, that cap is 70% CLTV across both credit tiers, 700 and 720. Credit above 700 buys comfort, not extra leverage.
4. Valuation. Because an investment line caps at $500,000, and full appraisals are required only above $500,000, these lines run on automated valuation and commonly close with no traditional appraisal. A borrower can still request a full appraisal.
5. Title. The property must sit in the borrower’s own name or in a revocable living trust. An LLC cannot hold title on these lines.
6. Draw at closing. The network expects at least 75% of the line to be drawn at closing, so the line is best sized to the actual need.
Lendmire arranges these lines through select wholesale partners and is never the lender. Every figure here is subject to lender guidelines and full file review.
What Does an Investment-Property Line Look Like on the Network?
The structure is simpler than most owners expect. A line on an investment property is a standalone line in first or second lien position. The draw period is five years, interest-only, followed by 25 years of full amortization. Pricing floats across both phases and never converts to fixed.
Market descriptions often differ. NerdWallet describes a typical rental line as a 10-year interest-only draw followed by repayment of up to 20 years. Treat that as a market-wide pattern. The network’s investment lines run the 5-and-25 structure only.
Line sizes run from $25,000 to $750,000 overall, but an investment property is capped at $500,000. Anything above $500,000 is primary-residence only, needs a 700 credit profile or better (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal.
Percentages make the sizing concrete. Say an owner’s rental carries a first mortgage equal to 55% of value. At 70% CLTV, the line can reach roughly 15% of value, up to the $500,000 ceiling. If the first mortgage already equals 65% of value, only about 5% of room remains. Older loans with heavy paydown are what make these lines workable.
Property types matter too. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condos, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural zoning are not offered. These home equity programs are available in Lendmire’s 16 full-service states, a narrower reach than the 41-market DSCR footprint.
How Do the Structures Compare?
Three paths cover most rental owners: a line against equity, a DSCR cash-out refinance, and paying the mortgage down with cash. Each has a different job.
| Factor | Home equity line | DSCR cash-out | Cash paydown |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Stays in place |
| Reviewed on | Credit, DTI, equity | Rent vs. payment | Nothing to qualify |
| Network leverage cap | 70% CLTV (investment) | 75% LTV (standard rental) | Not applicable |
| Liquidity after | Line stays open | Cash in hand | Locked in equity |
| Title | Individual or trust | LLC possible | Unchanged |
The DSCR cash-out figure is a ceiling for standard rentals, with about 6 months of seasoning as the common expectation. For short-term rentals, the network’s cash-out ceiling is 70%. LLC-held properties can generally use the DSCR route, depending on program guidelines.
The sharpest difference is what happens to the first mortgage. A line adds a second lien and leaves the existing loan alone. A cash-out replaces it. An owner with an older first mortgage worth keeping tends to prefer the line. An owner with a loan worth replacing, or with LLC title, tends to land on the cash-out.
Lendmire’s paying down a rental HELOC vs rolling it into a new first mortgage picks up where this comparison leaves off.
Does the Line Payment Hurt the DSCR on the Next Rental?
Generally no. A DSCR compares a property’s monthly rent to its own payment: principal, interest, taxes, insurance, and any HOA dues. Business-purpose loans like this are designed for non-owner-occupied investment properties, and they are reviewed differently from a standard owner-occupied mortgage. Because the test lives at the property level, the line’s payment does not normally enter the ratio.
Here is the catch. The line payment still exists. It hits the owner’s real cash flow and, on loans reviewed on personal debt ratios, it hits those too.
Most standard DSCR programs start around 1.00, and select programs begin there. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and leverage. None of that means a 1.00 file is a profitable one. Repairs, vacancy, management, utilities, and capital expenses are all outside the calculation.
Picture an investor who funds the 20% down payment on a purchase with a line, then finances the rest at 80% LTV. The DSCR may clear 1.2x and look fine on paper. Yet that investor now carries payments on a first mortgage and a floating line, with almost nothing of their own in the deal. A modest vacancy turns a clean ratio into a monthly loss. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Whether a DSCR program accepts borrowed funds for the down payment is program-specific. Reserves, commonly around 6 months of PITIA, often need to be the investor’s own seasoned cash. Confirm both points with the lender before drawing, not after.
Where Does the General Rule Break?
Several edge cases catch investors who assume the mechanics are uniform.
Draw-period expiry. The CFPB explains that payments are often significantly higher once the repayment period begins, and some plans require the full balance at once. A line used as a two- or three-year bridge needs an exit well before the draw phase ends. On the network’s investment lines, the exit point is five years out. Pricing also floats, so payments can move even without new draws.
LLC-held rentals. If the rental already sits in an LLC, a consumer-style line is usually off the table. The property would need a vesting change, or the owner would use a DSCR cash-out instead. Lendmire’s piece Rental HELOCs for LLC and Trust Owners: What Replaces Tax Returns covers this fork in detail.
Listed or recently listed properties. In several states, a property listed for sale, or listed within the past 60 days, is ineligible.
Portfolio limits. A borrower is limited to three lines, with combined exposure capped at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower owning more than 15 financed properties is not eligible.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family events season for 7 years, and a deed-in-lieu, pre-foreclosure, or short sale for 4, on investment files.
Mixed-purpose draws. If part of a draw funds a rental and part funds personal spending, records matter. 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.
Stacking. A borrowed down payment plus high-LTV financing can approach 100% total financing. The ratio still looks clean. The monthly reality does not.
What Does an Operator See in These Files?
Across the wholesale network, the files that go smoothly share a pattern. The owner opens the line well before contracting, draws only what the deal needs, and routes the money through a dedicated account. That paper trail helps the purchase lender source the down payment.
Files that struggle usually share a different pattern. The line is sized to the maximum, 75% of it gets drawn at closing, and the owner then discovers that coverage on the new property is thin. When the line carries most of the equity in the deal, there is little cushion left for a bad quarter.
What Does the Decision Look Like in Practice?
Run two scenarios in ratios and percentages.
An investor owns a rental with a low first mortgage, roughly half of current value, and wants to buy a second property. A 700-plus credit profile and sufficient equity make a line workable. Funding the down payment on a purchase at 70% LTV with the line leaves the first mortgage untouched. If the target rental clears around 1.25x on coverage, there is room for the line payment, vacancy, and repairs. This is the profile the strategy suits best. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
A second investor owns a rental that barely clears 1.00x and plans to cover the gap using draws on the line. That is the signal to stop. A line used to subsidize a weak property turns a rental problem into a collateral problem, because a failed rental can put the home or property securing the line at risk. The stronger move is a different submarket or a lower purchase price, not a larger line.
Paying down a mortgage on one property with a line against another deserves the same stress test. It makes sense when the loan being retired is the more costly debt and when the owner can carry a floating payment through a rough stretch. It makes less sense when the original mortgage is fixed and cheap. Swapping that for a floating line adds risk without a clear reward.
A simple way to decide:
- Lean paydown when reserves are thin, coverage is borderline, or the line would be sized near the ceiling.
- Lean invest when the target property clears strong coverage on its own and cash reserves stay intact after the draw.
- Lean hybrid when the owner can use a smaller line for part of the down payment and cash for the rest.

Frequently Asked Questions
Can I get a HELOC on a rental property?
Yes, though fewer lenders offer it and the terms are tighter than for a primary home. On the network, an investment-property line requires a 700 credit score, caps at 70% CLTV and $500,000, and must be titled to an individual or revocable trust. Eligibility is subject to lender guidelines and full file review.
Will the HELOC payment lower my DSCR on the next rental?
Generally not, because the ratio compares that property’s rent to its own payment. The line payment still reduces real monthly cash flow. It also counts on any loan that reviews personal debt ratios, so size the line with both tests in mind.
Can I use a HELOC as my down payment on a DSCR purchase?
It depends on the program. Some lenders accept borrowed funds for the down payment, and others want seasoned cash of the investor’s own. Reserves, commonly around 6 months of PITIA, often must come from the investor’s own funds. Confirm both points before drawing.
Is a HELOC or a DSCR cash-out refinance the better choice?
A line suits an owner who wants to keep a favorable first mortgage and stay flexible. A DSCR cash-out suits an owner who holds the property in an LLC, or whose rent supports a new first mortgage. Cash-outs on standard rentals top out around 75% LTV with roughly 6 months of seasoning. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
What happens when the draw period ends?
The line enters repayment, and payments often rise sharply because principal begins to amortize. On the network’s investment lines, a five-year interest-only draw is followed by 25 years of full amortization. Plan the exit, whether a payoff from cash or a refinance, before the draw ends.
