The Quick Read: This product is a floating-price line of credit secured by an investment property, where your deposits stand in for tax returns, but the lender still tests your credit, your combined equity, and a debt-to-income ratio calculated on the full line at its interest-only payment. Bank statements change how your income is documented. They do not loosen the equity, credit, or property tests. The lender reviews your file on documented income under the applicable program, subject to lender guidelines.
- On an investment property, the line needs a 700 credit profile and tops out at 70% combined loan-to-value (CLTV), with a maximum line of $500,000.
- The property must be titled in your own name or a revocable living trust. An LLC cannot hold title.
- Investment lines run a 5-year interest-only draw, then a 25-year fully amortizing repayment, and the pricing floats the whole way.
- Debt-to-income is tested on the interest-only payment for the maximum draw, not the amount you plan to use.
- A DSCR loan tests the property’s rent instead of your personal income, which is often the better fit for large or LLC-held portfolios.
What Does “Interest-Only Rental” Actually Mean?
The phrase has two meanings, and lenders treat them differently. It can describe the new line, whose draw period is interest-only. It can also describe a rental whose existing first mortgage is interest-only. Many investors have both at once.
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.
Meaning one: the line itself is interest-only. During the draw period you pay only the interest on what you have borrowed. On an investment property, that draw lasts five years. Then the line moves into a 25-year fully amortizing repayment, where each payment includes principal. Pricing floats through both phases and never converts to a fixed structure.
Meaning two: your first mortgage is interest-only. The line can sit in first or second lien position. If it sits behind an interest-only first mortgage, the lender still counts that existing payment against your debt-to-income ratio. Your first-lien balance may also not be shrinking. CLTV is the existing liens plus the new line, divided by the property’s value, so a balance that never falls leaves less room for the new line.
Key Terms Defined
HELOC: A home equity line of credit, a revolving line you can borrow from repeatedly against the equity in a property.
Draw period: The stretch when you can borrow from the line and, here, pay interest only.
Repayment period: The stretch after the draw ends, when borrowing stops and payments include principal.
CLTV (combined loan-to-value): All loans secured by the property, including the new line, divided by the property’s value.
DTI (debt-to-income): Your monthly debt payments divided by your documented monthly income.
Bank statement income: Income estimated from deposits in your business or personal accounts instead of tax returns.
Vesting: How title to the property is held, such as in your own name, in a trust, or in an LLC.
DSCR: Debt service coverage ratio, which divides a rental’s income by its monthly housing payment (principal, interest, taxes, insurance, and any association dues).
Requirements at a Glance
On an investment property, the requirements are tighter than on a primary home. Credit, leverage, and line size all narrow. The table below compares the two so you can see where the rental sits. Primary-residence figures are shown only for contrast and never apply to a rental.
| Factor | Investment property | Primary residence |
|---|---|---|
| Minimum credit | 700 | 600 program floor |
| Max CLTV | 70% | Up to 90%, only at 720+ |
| Line size | $25,000 to $500,000 | Up to $750,000 |
| Draw / repayment | 5 years / 25 years | 3/17 or 5/25 |
A few details sit behind those rows. Both 720 and 700 credit profiles reach 70% CLTV on an investment property, so a higher score buys eligibility, not extra leverage. Seven hundred is a hard floor with no tier beneath it. The score comes from a single-bureau model keyed to the primary wage earner, and the report must be no more than 90 days old at closing.
Because an investment line caps at $500,000, it falls in the lane where an automated valuation is the ordinary method and a traditional appraisal is commonly not required. A higher CLTV may call for a second valuation, and you may request a full appraisal in any case. All figures are program guidance subject to lender guidelines and full file review, not a commitment to lend.
At least 75% of the line is drawn at closing. A minimum applies to later draws. That up-front draw matters when you decide how large a line to request.
How Do Lenders Turn Deposits Into Income?
Lenders turn deposits into income by cleaning the account first, then applying an expense factor. Bank statements are not a shortcut around underwriting. They are a different way to document the same income the lender would otherwise read from your returns.
The process runs in four steps:
1. Choose the account type. Business or personal statements can be used. A business account needs a 680 minimum for the deposit analysis, which never binds on an investment line because that line already floors at 700.
2. Strip out what is not income. Transfers between your own accounts and one-off deposits come out. Loan proceeds and refundable security deposits are the kinds of items lenders commonly screen out as well.
3. Apply an expense factor. On business deposits, the lender applies an expense factor, because deposits are revenue and not profit.
4. Divide by the period. What remains becomes your monthly qualifying income.
Here is a modeled example, not a market figure. Say a landlord’s business account shows deposits, and 20% of them turn out to be transfers between their own accounts. That 20% disappears at once. The expense factor then trims what remains. The surviving number can be well below the headline deposit total. It can also be higher than the number on a tax return full of write-offs, which is the whole point of the route.
Rent counts here only as deposits in your account. The lender does not run a property-level rent test, which is the sharpest contrast with DSCR. Commingled accounts, where rent, personal spending, and other business activity all flow through one account, make the cleanup harder. Separating them before you apply gives the reviewer a clearer picture.
The number of statement months varies by lender, so confirm it before you pull documents.
How the Interest-Only Payment Gets Tested
The lender tests DTI on the interest-only payment calculated on the maximum draw. It does not use the amount you plan to borrow. That is the most misunderstood rule in this product.
Three different payments are in play:
- The tested payment. The interest-only payment on the full line, used for the DTI ceiling of 50%.
- The paid payment. The interest-only payment on only what you have actually drawn, which may be much lower.
- The post-draw payment. The fully amortizing payment once the 5-year draw ends.
Run the numbers on a modeled case. Say existing obligations already use 34% of your documented monthly income. A full-draw interest-only payment on a modest line adds 11 points, landing at 45%. That passes. Now size the line larger so the full-draw payment adds 18 points. You land at 52% and fail the 50% ceiling, even if you never intended to draw it all.
This also means an unused line still consumes DTI capacity. For a portfolio investor with many financed properties, that can be the deciding factor. Two smaller facts matter here: DTI above 45% requires a 680 minimum credit profile, and the 45% limit for 600–679 profiles is moot on an investment line because 700 is the floor.
What Happens When the Interest-Only Period Ends?
The payment steps up, often sharply. When the five-year draw ends, borrowing stops and the 25-year amortizing repayment begins. The Consumer Financial Protection Bureau’s HELOC explainer describes the same pattern on lines generally. It calls the HELOC an open-end line, notes that payments are often significantly higher once repayment starts, and warns that in some cases the whole balance can come due.
The step-up is not the only moving piece. Because pricing floats, the CFPB’s HELOC brochure points out that your payment can change even when you draw nothing more. A line that felt manageable at the start can feel different five years in, on a larger balance with principal added.
Bankrate’s overview of HELOC draw periods also flags that some lines carry early-repayment penalties. Read the line agreement for that before you plan to pay it off early.
A practical stress test is simple. Before you open the line, work out what the post-draw payment would look like on the balance you expect to carry. Then check whether the rental’s income, plus your other income, absorbs it. If the answer depends on the draw period never ending, the line is the wrong tool.
This floating structure is also why the line tends to suit staged or shorter-term capital needs. A long-hold investor who wants stable financing usually looks elsewhere. The CFPB’s examples of ten-year draws are generic. Investment lines on this network run five.
Title, Property Type, and Exposure Limits
Title is the first gate. Fee simple or leasehold interests must be held by you as an individual or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. That is the sharpest structural difference from a DSCR loan. If your rental already sits in an LLC, you face a vesting change or a different product.
Property type is the second gate. Eligible properties include single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial buildings, mixed-use properties, and agricultural zoning are not offered.
Exposure limits are the third. A borrower is limited to three lines, with combined exposure caps that differ by program. A borrower who owns more than 15 financed properties is not eligible. Credit history rules also apply: a bankruptcy needs four years of seasoning from discharge or dismissal, and investment files follow a seven-year path for foreclosure and four years for a deed-in-lieu, pre-foreclosure, or short sale.
The naming quirk catches people. Some banks will not write a HELOC on a rental but will offer a line of credit secured by investment property. A BiggerPockets thread on HELOCs for investment property also notes that a HELOAN is a closed-end second mortgage that cannot be drawn on repeatedly. Ask which product you are being offered.
Many large retail lenders decline rentals entirely. That is one reason brokered wholesale programs exist. Availability for this HELOC product also runs narrower than the DSCR footprint. Lendmire arranges DSCR loans in 41 markets, including Washington, D.C., but the HELOC is available only in its 16 full-service states, so confirm your state first.
A short practitioner note: files on this product stall less over credit than over title and exposure. A property sitting in an LLC, or a borrower already near the three-line limit, ends the conversation before income is ever reviewed. Checking those two items first saves a lot of document gathering.
Document Checklist (and Why Files Stall)
Gather these before you apply:
- Income: Business or personal bank statements covering the lender’s required period, plus a profit-and-loss statement if the reviewer asks for one.
- Property: Lease or rent roll, current insurance, a mortgage statement for each existing lien, and the property’s tax information.
- Ownership: The deed or vesting document, and trust paperwork if a revocable living trust holds title.
- Credit and history: A report no more than 90 days old at closing, plus explanations for any derogatory items.
Files commonly stall for four reasons:
1. Title sits in an LLC.
2. Rent, personal spending, and business activity run through one account, and the cleanup takes time.
3. The requested line is too large for the full-draw DTI test.
4. Combined leverage comes in above 70% CLTV on the investment property.
Bank Statement HELOC or DSCR Cash-Out?
The two products test different things. A bank statement line tests your personal income through DTI. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Full details sit in Lendmire’s complete DSCR loans guide.
| Factor | Bank statement HELOC | DSCR cash-out refinance |
|---|---|---|
| What is tested | Your DTI from deposits | Rent against the payment |
| Title | You or revocable trust | LLC possible |
| Leverage | 70% CLTV, investment | Around 75% LTV, standard rental |
| Structure | Floating, 5-year IO | 30-year fixed spine |
| First mortgage | Stays in place | Refinanced |
Two points sit behind that table. DSCR cash-out on a standard rental tops out around 75% LTV across most of the network, with about six months of seasoning as the common expectation. LLC-titled loans are possible, subject to lender program eligibility. A DSCR file compares rent with PITIA only, so clearing it does not mean the property produces positive cash flow after repairs, vacancy, management, and utilities. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Here is how the choice usually plays out:
- Self-employed investor with heavy write-offs, individual title, and a low-cost first lien you want to keep: the bank statement line may fit, if the DTI test passes on the full-draw payment.
- Heavily leveraged portfolio investor or LLC owner: DSCR often fits better, because there is no personal income test and the entity can hold title.
- Long-hold investor who wants stable financing: the fixed DSCR structure generally suits that goal better than a floating line.
- Someone with strong tax returns and a simple profile: full documentation may be the cleaner route, and bank statements add nothing.
The strongest files clear two tests: enough equity and enough income. A larger down payment or more equity does not erase credit floors, leverage caps, or property eligibility.
Frequently Asked Questions
Do I need tax returns for this kind of line on a rental?
Not under the bank statement program, which documents income from deposits instead. The lender still verifies that income, analyzes the deposits, and tests credit, equity, and DTI. Whether a given file qualifies stays subject to lender guidelines.
Does my rental income count toward qualifying?
Only as deposits in the account you submit. The lender does not run a separate property-level rent test, which is what makes the product different from DSCR. If rent never reaches the account, it does not help the file.
Can an LLC-owned rental qualify?
No. Title must be held by you personally or by a revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out may fit instead, subject to program terms.
What if my first mortgage is interest-only?
It is still counted. The lender includes the existing first-lien payment in your DTI, and CLTV adds the existing balance to the new line. Because an interest-only first mortgage may not be paying down, equity does not grow through amortization.
Will an unused line still affect my debt-to-income ratio?
Yes. Qualification uses the interest-only payment on the maximum draw, so the full line weighs on the test whether you borrow or not. Asking for a smaller line is often the cleanest fix when DTI is tight.
