The Quick Read: For a first rental, an interest-only DSCR loan is usually the stronger tool for buying the property, because it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, while a rental home equity loan only works after you own a rental with real equity in it.
- A DSCR loan tests the property. A home equity line tests you: credit, income and debt load.
- A first rental has no equity yet, so an equity loan on that rental is not a purchase tool.
- Interest-only lowers the payment used in the coverage test, but it builds no equity and the payment rises later.
- An investment equity line through the network caps at 70% CLTV and $500,000, and the line cannot be titled in an LLC.
- The two can work in sequence: equity from a primary home can fund the down payment on a DSCR purchase.
The Honest Answer First
These two loans solve different problems, and for a first rental they rarely compete head to head.
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.
An interest-only DSCR loan is for the investor who wants to buy a rental and let the rent carry the file. A rental home equity loan is for the investor who already owns a rental with equity and wants cash out without touching the first mortgage. If you own neither yet, the choice is really about where the down payment comes from.
Across the wholesale network Lendmire works with, the pattern is consistent. Thin-income or self-employed buyers and anyone planning to hold title in an LLC lean DSCR. Salaried borrowers with low debt and a paid-down property lean toward the equity line. Many first-time landlords end up using both, one after the other.
Side-by-Side
This table shows how each product is typically built. The DSCR column reflects select lenders in Lendmire’s wholesale network. The equity column reflects the investment-property line parameters in that same network.
| Factor | Interest-Only DSCR Loan | Rental Home Equity Line |
|---|---|---|
| What is tested | Rent versus the property’s obligation | Borrower credit, income, DTI |
| Documentation | Appraisal with rent schedule, lease, entity papers, reserves | Income, credit and asset documents |
| Collateral | The rental being bought or refinanced | A rental you already own |
| Lien position | First lien on purchase | First or second lien |
| Entity vesting | LLC allowed, subject to lender program eligibility | Individual or revocable trust only |
| Property types | Single-family through small multifamily; manufactured and log homes not offered | Similar, but manufactured homes, co-ops and condotels not offered |
| Credit | 620 floor in parts of the network; most want around 660; 700+ for top leverage | 700 minimum on investment lines |
| Leverage | 75%-80% LTV on an investment purchase; select programs reach 85% at about 700+ | 70% CLTV on an investment property |
| Size | Up to $3,000,000 on standard programs | $25,000 to $500,000 on investment |
| Reserves | Commonly around 6 months of PITIA, varying by file | Set by the lender on review |
| Structure | Interest-only period through select lenders | 5-year draw, then 25-year repayment |
Two rows carry most of the weight: what is tested and who can hold title. Everything else follows from them.
How an Interest-Only DSCR Loan Works on a First Rental
The coverage ratio is monthly rent divided by the monthly obligation. On a standard amortizing loan, that obligation is principal, interest, taxes, insurance and association dues (PITIA). On an interest-only structure, the scheduled principal drops out, so the denominator shrinks and the ratio rises.
That is the whole appeal. A deal that sits borderline on a fully amortizing payment can clear on an interest-only one. Interest-only periods are available through select lenders in the network, and the same lenders also offer extended terms such as 40-year structures. The spine of the market is still the 30-year fixed.
Some lenders qualify the file on the interest-only payment. Others qualify as if principal were due from day one. That difference decides whether the structure actually helps your number, so ask which method the lender uses before you price the deal.
Here is the catch. When the interest-only window ends, principal starts and the payment steps up. The loan balance has not moved in the meantime. A first-time landlord who budgets only for the early payment is setting up a problem for later.
Prepayment penalties are common on DSCR loans, and terms vary by lender. They matter if you plan to refinance when the interest-only period closes.
Why Clearing 1.00 Is Not the Same as Cash Flow
The DSCR test compares rent to PITIA and nothing else. Repairs, vacancy, management, utilities and capital expenses sit outside it. A file that clears the test can still lose money in a bad month.
Coverage floors also differ by program. Many select programs start at 1.00. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better leverage and pricing, so interest-only can help on both sides of the file.
A larger down payment lowers the monthly obligation and can lift the ratio. It does not erase credit floors, leverage caps, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rent.
The First-Rental Sequencing Problem
A rental home equity loan secured by the rental needs a rental that exists. On a first purchase, you have no equity in the property you are buying beyond your down payment. So the real choice is often different from the one in the title.
The practical paths look like this:
1. DSCR purchase with cash savings. Put 20%-25% down on most files, and the rent carries the qualification.
2. Equity line on your primary home, then a DSCR purchase. The line funds the down payment. On a primary residence, the network’s ceiling reaches 90% CLTV, but only at a 720-or-better credit profile. Most borrowers sit below that.
3. DSCR purchase first, equity line on the rental later. After you own the rental and have built equity, an investment line can pull cash out at up to 70% CLTV.
The second path has a trap. Borrowing against your home to buy a rental puts the home behind two debts. The new line’s payment also counts toward your personal DTI, which tops out at 50% on these lines. Lenders review the source of down payment funds, and rules on borrowed funds vary by lender, so confirm the lender’s position before you commit to the plan.

How a Rental Home Equity Line Works
An investment equity line sits on a property you already own. Sizing is a percentage of the appraised value minus what you owe, as the CFPB’s HELOC booklet describes in general terms. On an investment property in Lendmire’s network, that percentage is 70% CLTV, and credit above 700 buys eligibility rather than extra leverage.
The mechanics:
- The line runs $25,000 to $500,000 on an investment property.
- It runs a 5-year draw and a 25-year repayment period, and investment lines use that structure only.
- At least 75% of the line is drawn at closing.
- Pricing floats through draw and repayment and does not convert to fixed.
- The minimum credit score is 700, and the DTI limit is 50%.
- Because the line caps at $500,000, valuation is typically automated and often involves no traditional appraisal.
- The line can be a first or second lien.
The title rule is the sharpest difference from a DSCR loan. An individual or a revocable living trust holds title. An LLC, a corporation, a partnership or a land trust cannot. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead.
Availability is also narrower. Investment equity lines are limited to 16 full-service states. The DSCR footprint covers 41 markets, including Washington, D.C.
Lendmire’s explanation of rental HELOC vs home HELOC equity limits with a low first lien goes deeper on the sizing math.
When an Interest-Only DSCR Loan Is the Better Fit
Pick the DSCR route when the property is the strongest part of your file.
- You are buying, not borrowing against something. DSCR is built as a purchase first lien. The equity line is not.
- Your personal income is hard to document. Self-employed investors and anyone with heavy existing debt do better when the file runs on rent. Qualification still depends on credit, reserves and property review.
- You want an LLC. DSCR loans commonly allow LLC vesting, depending on lender program eligibility. The equity line does not.
- The rent barely clears on amortizing payments. Interest-only can lift the coverage number, which may support a stronger file.
- You plan to scale. DSCR files are underwritten per property and do not run on personal DTI. An equity line adds to personal debt each time.
- You want the risk to stay on the rental. The DSCR loan is secured by the investment property. The home you live in is not on the line.
Interest-only fits best when you have a clear plan for the end of the window. That could mean a rent increase, a refinance, a sale or the move to amortization. If the plan is vague, the fully amortizing version is safer.
When a Rental Home Equity Loan Is the Better Fit
Pick the equity route when you already own a property with real equity and a clean personal profile.
- You hold a paid-down rental or primary home. The loan sits on equity you already have.
- You are salaried with low debt. A 700 score and DTI inside 50% make the file straightforward.
- You need flexible access to cash. A line lets you draw as projects come up, within the closing draw rules above.
- You want to keep a good first mortgage in place. A second-lien line leaves the first loan alone.
- The cash is for a down payment, not the whole purchase. Using the line this way can cut the cash you need to bring to the DSCR closing.
The risks are real. A line on your own home puts that home behind the debt, and the CFPB booklet warns that missing payments can cost you the property. Repayment also steps up once the draw period ends.
Property eligibility matters too. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural zoning are not offered. A property listed for sale, or listed in the past 60 days, is ineligible in several states.
How the Interest-Only Window Changes the Coverage Number
Here is a rough run on the logic. Take a rental whose rent covers an amortizing payment at a ratio just under 1.00. Remove principal from the denominator. The same rent now clears 1.00 and may land in the 1.2x range, depending on loan size and term.
Then the window closes. The payment returns to the amortizing level, and the coverage ratio falls back. If you refinanced into a new interest-only loan, you start the cycle over. If you did not, you need rent that can carry the higher obligation.
The equity line behaves differently. It is qualified on the interest-only payment calculated at the maximum draw, then converts to a fully amortizing repayment at the end of the draw. That is a built-in step up, and it is the same shape of risk.
Both products have a payment jump. The question is which one you can plan around. With DSCR, the lender watches the property. With the equity line, you carry the personal debt load into every later application.
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.
Can You Combine Them?
Yes, and for a first rental it is often the practical plan. Use equity from a primary home for the down payment. Buy the rental with a DSCR loan. The DSCR file qualifies primarily on property-level rental income, and the equity line’s payment sits in your personal debt picture.
A few cautions apply. The equity line has to close before the DSCR purchase, which adds a second approval to the plan. Lenders review where down payment funds came from, and some limit borrowed funds. The combined debt also leaves less cushion if the rental sits vacant.
Business-purpose treatment adds one more layer. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The Federal Reserve’s Reg Z manual lists credit extended primarily for business purposes among the exempt transactions. Law-firm analysis from Hunton cautions that business purpose does not mean exempt from every compliance obligation. Lenders document purpose, so expect to sign a business-purpose certification.
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 Balanced Verdict
If you are buying your first rental, start with the DSCR loan. It is the product built for the purchase, and interest-only can help the coverage number when the rent is close. Use it with a plan for the end of the window.
If you already own property with equity, an investment equity line is a clean way to pull cash without replacing your first mortgage. It tests you instead of the property, so your credit, DTI and title all matter.
For many first-time landlords the honest answer is both, in order. Pull equity from a primary home if you have it, buy with DSCR, and revisit the equity line once the rental has built its own equity. Whichever route you take, size the deal on the full payment, not just the interest-only one.
Lendmire’s complete DSCR loans guide covers leverage tiers, credit floors and reserve rules for the purchase side. Reserves vary by lender, leverage, loan size and transaction type. Around 6 months of PITIA is common. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about 9 months.
Key Terms Defined
DSCR (debt service coverage ratio): Monthly rental income divided by the property’s monthly obligation, used to test whether the rent covers the loan.
PITIA: Principal, interest, taxes, insurance and association dues, the full monthly obligation on an amortizing loan.
Interest-only period: A stretch at the start of the loan when payments cover interest but not principal.
CLTV (combined loan-to-value): All loans secured by the property, added together, divided by the property’s value.
Lien position: The order in which loans on a property are repaid, with a first lien ahead of a second.
Draw period: The stretch when you can borrow against an equity line before repayment begins.
Frequently Asked Questions
Can I use a home equity loan to buy my first rental?
Not directly on the rental, because you have no equity in a property you have not bought. You can borrow against a primary home you own and use the cash toward the down payment. The lender will review where those funds came from, and rules on borrowed down payment funds vary by lender.
Does an interest-only DSCR loan build equity?
Not through payments during the interest-only window, because no principal is paid. Equity grows only if the property appreciates or you make extra principal payments. Plan for the later payment step-up so the balance does not catch you unprepared.
Can an LLC borrow through a rental equity line?
No on the network’s investment lines. Title must be held by an individual or a revocable living trust. DSCR loans commonly allow LLC borrowers, subject to lender program eligibility, so an LLC-owned rental usually points to DSCR.
What credit score do I need for each?
The investment equity line needs 700 at minimum. The DSCR minimum depends on lender guidelines and the full file.
Does the equity line affect my DSCR file?
The line’s payment is personal debt and usually sits outside the new rental’s coverage ratio. It still counts when a lender reviews your overall picture and reserves. Run both the property test and your own cash flow before you commit.
