The Quick Read: Using an equity line on a rental you already own to fund your next down payment works as two separate deals. The line puts cash in your hands based on you as a borrower. A separate DSCR purchase loan then buys the property based on its rent, so each approval can fail on its own.
- On investment properties, lines through Lendmire’s wholesale partners top out at 70% combined loan-to-value (CLTV), need a 700 credit score, and cap at $500,000.
- The purchase lender decides whether borrowed money counts as your down payment. Ask before you draw.
- The new property’s coverage ratio tests only its own payment. The line’s payment lands on your personal cash flow and debt picture.
- A rental held in an LLC generally can’t take this kind of line, so check title first.
Think of it as a relay. The first runner (the line) has to hand off cleanly to the second (the purchase loan). Most failed files drop the baton at the handoff, not at the start.
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
DSCR (debt service coverage ratio): monthly rent divided by the property’s full monthly housing payment. It measures whether the rent covers the loan.
HELOC (home equity line of credit): a revolving line secured by a property you own. You draw what you need, up to a set limit.
CLTV (combined loan-to-value): all loans against a property, added together, as a percentage of its value.
PITIA: principal, interest, taxes, insurance, and any association dues. It is the full monthly housing payment that rent is measured against.
Second lien: a loan that sits behind another loan on the same property. If the property is sold or foreclosed, the first lien is paid first.
Seasoning: the waiting period a lender wants before it treats funds or a property as settled. It can apply to a refinance or to borrowed money.
Source of funds: the paper trail showing where your down payment came from.
What Does a Rental HELOC Behind a DSCR Loan Actually Mean?
It means you own a rental financed with a DSCR first mortgage, and you add an equity line in second position behind it. You then use the cash toward the next purchase. The phrase “investment property HELOC” is a market label, not one standard product, and the label alone does not tell you how a file will be underwritten.
Depending on who uses the term, it can describe three different structures:
| Structure | Underwritten on | What happens to the first loan |
|---|---|---|
| Revolving equity line | You (credit, DTI, equity) | Stays in place |
| Closed-end second lien | You, or rent, by lender | Stays in place |
| DSCR cash-out refinance | The property’s rent | Replaced by a new loan |
Across the wholesale network Lendmire works with, a standalone investment-property line is underwritten on the borrower. It can sit in first or second position. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment.
Two features surprise people. At least 75% of the line is drawn at closing, so this is not a “borrow only when needed” tool. And pricing floats through both the draw and repayment periods. It never converts to fixed.
That second point matters because other products differ. A few plans in the broader market let you lock in a fixed portion. These lines do not.
Two Approvals, Not One
You are applying twice. The line underwriter studies you and your equity. The DSCR underwriter studies the property you want to buy. Passing one says nothing about the other.
| Item | Equity line | DSCR purchase loan |
|---|---|---|
| What it reads | Your credit, DTI, equity, existing liens | Rent against PITIA, plus credit and reserves |
| Typical score | 700 minimum on investment | Around 660 on most programs; 620 in parts of the network |
| Leverage | Up to 70% CLTV on investment | Most files 75%–80% LTV; select programs 85% at 700+ |
| Valuation | Automated, commonly no traditional appraisal | Property appraisal with a rent schedule |
| Size | $25,000 to $500,000 on investment | Up to $3,000,000 on standard programs |
On the line side, DTI (your monthly debts compared to your income) tops out at 50%. The line is qualified on the interest-only payment calculated on the maximum draw, not on what you plan to pull. A single score is keyed to the primary wage earner. Investment lines are offered only in Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint. Everything here is subject to lender guidelines and full file review.
On the purchase side, 1.00 coverage is where select programs start, not a universal bar. Stronger ratios open better pricing and leverage. Reserves vary by lender, leverage, and loan size. About 6 months of PITIA is common, and larger loans typically step up to about 9 months.
Can Your First Lender Stop You?
Possibly, and it is cheap to find out. Your existing DSCR first mortgage has a note and a deed of trust. Some loan documents restrict additional liens or certain transfers of the property.
Read both before you apply for the line. Look for language about additional liens, subordinate financing, and changes in title. Then ask the servicer directly, and get the answer in writing. A verbal “that should be fine” is not a plan.
This check is separate from what the line lender wants. A line lender may be willing to lend while your first loan documents still object. Clear both.
The Title Check Most Investors Skip
An equity line needs title held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. This is the sharpest structural difference from a DSCR loan, which can often be placed on an entity, subject to program terms.
So a rental already deeded to an LLC usually can’t take the line as it stands. You have two workarounds:
1. Change vesting to your name or a revocable trust, after confirming your first-loan documents allow it.
2. Skip the line and do a DSCR cash-out refinance on that rental instead.
Neither is automatic. Changing title can trigger its own review under the existing first loan, which is another reason to read those documents first.
Sizing the Line: Combined Leverage Is the Real Cap
The formula is simple. Take the property value, multiply by the CLTV cap, and subtract what you owe on the first loan. On an investment property here, the cap is 70% CLTV, and the line can’t exceed $500,000.
Credit above 700 does not buy more leverage on an investment line. Scores of 700 and 720 both reach the same 70% ceiling. The 700 is a hard floor with no tier beneath it.
Now run it backward. Say your rental’s DSCR first mortgage sits at 60% of the property’s value. The line has 10 points of value to work with. If the first loan sits at 55%, you have 15 points. If you bought that rental at 75% or 80% LTV and haven’t paid it down, you are already over 70% combined, and the line has no room. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
That last case is the common trap. A high-leverage DSCR purchase leaves nothing behind it until appreciation or paydown opens the gap. If the numbers don’t fit, a DSCR cash-out refinance on the rental, which reaches about 75% LTV on most standard rentals, may fit better. Cash-out files commonly expect about 6 months of seasoning.
The line often can’t cover a full purchase price anyway. It can fund the down payment and costs, and the DSCR loan supplies the rest.
How the Draw and Repayment Periods Work
An equity line is an open-end credit line. The Consumer Financial Protection Bureau describes a draw period that “could last 10 years, for example.” It also says these lines usually carry variable pricing, so payments can change from month to month.
During the draw period, many plans allow interest-only payments. The CFPB’s HELOC booklet notes that under those plans you pay nothing toward principal. Payments then step up when the repayment phase begins and principal is added.
That is the textbook benefit of a line. On the investment lines described above, the 75%-drawn-at-closing rule trims it, because most of the limit starts accruing cost on day one.
Plan for the transition. A 5-year interest-only draw feels cheap while it lasts. The repayment phase is where a payment that looked manageable can change shape.
Turning the Draw Into a Down Payment
Here is the sequence that works best. Each step protects the next.
1. Ask the DSCR purchase lender first. Confirm whether borrowed funds can serve as a down payment, and what documents they want. Acceptance is not universal. Investors on BiggerPockets report that many lenders dislike borrowed down payments, so the lender’s own guidelines decide this.
2. Clear the first-lien and title checks described above.
3. Close the line and draw into your own account. Keep the money in your name.
4. Document the trail. The purchase underwriter will trace large deposits back to the borrowed source. Ask whether any seasoning applies.
5. Close the DSCR purchase. The new payment is tested against the new property’s rent.
6. Plan the exit. Pay the line down, or refinance the new property later and retire the line.
Treat down payment and reserves as two different buckets. Reserves, commonly around 6 months of PITIA, are often expected to be your own liquid funds. Borrowed money may be accepted for one bucket and not the other, so ask the lender which applies to each.
Also understand what you’ve built. A borrowed down payment is effectively 100% financing on the purchase. The line’s lender sees your debt. The purchase lender sees your leverage. Your real constraint is how much stacked leverage you can tolerate.

DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Where Cash Flow Breaks (Not the DSCR)
The DSCR on the new purchase tests rent against that property’s PITIA only. The line’s payment generally sits outside that ratio. It shows up in your personal debt picture and may affect DTI on the line itself.
So a purchase can clear the coverage test and still strain you. Clearing 1.00 is not the same as positive cash flow.
| Inside the DSCR | Outside the DSCR |
|---|---|
| Rent | Repairs and maintenance |
| Principal and interest | Vacancy |
| Taxes and insurance | Management and utilities |
| Association dues | Capital expenses; the line’s payment |
A second lien also loads the property you borrowed against. Even if the lender tests coverage only on the first loan, you should run the rent against both payments. If it only works when the rent never dips, you have a fragile deal, not a coverage cushion.
Picture an investor whose first rental clears the first loan with comfortable room. Add a line payment, and that same rent now has far less margin. Add a vacancy, and you are paying both notes from personal income. That is the scenario to stress-test before you sign, because nobody else will.
One tax sentence: 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.
Where the General Rule Breaks
- A line on your primary home. Primary-residence lines reach up to 90% CLTV, but only at a 720 or better credit profile. That gives more room than a rental line. It also puts your residence behind an investment bet.
- Someone else’s line. A parent’s HELOC is not your down payment. Ownership and source-of-funds tracing both stand in the way.
- A bank decline. Many banks simply don’t lend on rentals. A decline is often a product-policy answer, not a verdict on you.
- Exposure limits. A borrower is limited to three lines on this network. An investor with more than 15 financed properties isn’t eligible.
- Property type. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs. Condos, including non-warrantable ones, and 2–4 unit properties can be eligible on the line side.
- A DSCR loan in second position. A DSCR loan generally doesn’t sit behind another loan. That is why the line and the DSCR purchase usually land on different properties.
- Thin coverage on the new deal. A separate select-lender path goes below 1.00 coverage, with leverage and terms adjusted. Adding borrowed down payment on top of that stacks risk.

Should You Actually Do It?
This is a genuine judgment call. The strategy works when equity is real, the rent has cushion, and your personal income can carry the line’s payment if a tenant leaves. It fails when the line is the only thing making the deal work.
Run this checklist before you apply:
1. Does the first loan’s paperwork allow a second lien?
2. Is title in your name or a revocable trust?
3. Does your equity fit under 70% CLTV for an investment line?
4. Does the purchase lender accept borrowed down payment, and what proof do they want?
5. Does the new property clear its own coverage test with room?
6. Could you carry both payments through a vacancy?
If you answer no to two or more, consider the alternatives: a DSCR cash-out refinance on the existing rental, a larger down payment from savings, or waiting for more paydown.
Frequently Asked Questions
Does the HELOC payment lower my DSCR on the new property?
Not directly. The coverage ratio on the purchase compares that property’s rent to its own PITIA. The line’s payment generally sits outside it, but it affects your personal cash flow and the line’s DTI test.
Can a HELOC be my only down payment source?
It depends on the purchase lender. Some accept borrowed funds with documentation, and others don’t. Reserves are often expected from your own liquid funds, so confirm both buckets with the lender before drawing.
Can an LLC-owned rental get one?
Generally not as titled. These lines require individual or revocable-trust ownership. A vesting change or a DSCR cash-out refinance are the usual workarounds, and the DSCR loan itself can sometimes be placed on an LLC, subject to program terms.
Is a DSCR HELOC the same as a regular HELOC?
No. The term is a market label that can mean a revolving line, a closed-end second, or a rent-qualified cash-out refinance. Ask what the product is underwritten on before you compare it with anything.
What if the bank says no?
Try a lender that writes lines on investment collateral. If title or leverage is the obstacle, a DSCR cash-out refinance may replace the line entirely, with about 75% LTV on a standard rental and about 6 months of seasoning commonly expected.
