The Quick Read: A HELOC offer letter lists one creditor’s terms and ranks no one, and on a rental property the line it offers depends on your credit, your combined loan-to-value after the first mortgage, how the property is titled, and which wholesale program fits your file.
- On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum score and lines up to $500,000.
- The offer letter fixes the limit, the index and margin, the caps, the draw and repayment lengths, and the minimum draw.
- On the investment line, the property must sit in your own name or a revocable trust, not an LLC.
- If the rent has to qualify the loan instead of you, a DSCR cash-out refinance is the usual pivot.
A ranked list of banks answers a different question than the one a rental owner has. Your question is what a lender will actually offer on this property, to this borrower, and how to read the letter that says.
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.
Lendmire is a mortgage broker. It works with a network of wholesale HELOC lenders and is never the lender itself. This article names no lenders for that reason. The right provider depends on your property type, credit profile, leverage need, and documents, and a broker matches the file to the program.
Key Terms Defined
HELOC: A home equity line of credit. It is a revolving line secured by a property you already own, and you borrow against it as needed up to a limit.
CLTV (combined loan-to-value): All loans secured by the property, including the new line, divided by the property’s value.
Draw period: The stretch when you can borrow. Payments during it are usually interest only.
Repayment period: The stretch after the draw period ends. You can no longer borrow, and payments must cover principal and interest.
Index and margin: A variable rate is a public benchmark (the index) plus a fixed add-on (the margin). The offer letter names both.
DSCR (debt service coverage ratio): Monthly rent divided by the full monthly housing payment: principal, interest, taxes, insurance, and any HOA dues. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Vesting: How title to the property is held, such as in your personal name, a trust, or an LLC.
What Does a HELOC Offer Letter Actually Show?
An offer or commitment letter fixes the contract terms in writing. Read it for six items: the credit limit, the index and margin, the rate caps, the draw and repayment lengths, any minimum draw, and the fees.
The federal consumer-finance regulator’s HELOC booklet lists the same terms as the ones to check. It adds that a variable rate must be tied to a publicly available index. It also notes that lenders sometimes offer a temporarily discounted introductory rate. Look for the line that says what the rate reverts to, because that is the number you will live with.
Variable-rate lines also move without any action from you. The federal consumer-finance regulator’s HELOC brochure points out that monthly payments may change even if you do not draw more. A letter that looks affordable on day one is describing a moving target.
Draw and repayment lengths vary across the market. NerdWallet describes a draw period of about 10 years followed by repayment of up to 20 years. That is a market-wide description. On the network’s investment-property line, the structure is a 5-year interest-only draw followed by a 25-year fully amortizing repayment, and it is the only structure offered on investment properties.
Some lines also carry a balloon feature, which means the whole balance comes due when the draw period ends. Experian flags this as something to look for. If your letter mentions a balloon, plan the exit before you sign.
How Does Underwriting Size the Line?
The lender reviews you, not the rent. On a conventional investment-property HELOC, the file turns on your credit, your debt-to-income ratio (DTI), the equity left after the first mortgage, the property type, the valuation, and the vesting.
Sizing runs on one formula. Take the property value, multiply by the CLTV ceiling, and subtract the existing liens. The result is the most the line can be. The full commitment counts toward CLTV, not just the amount you draw, so an unused line still uses up headroom.
Here is how that looks in percentages. Say the first mortgage already uses about 55% of a rental’s value, and the ceiling is 70%. That leaves roughly 15 points of the property’s value for the line. A small gap like that is why many rental owners find the approved limit disappointing.
The network’s parameters for the investment-property line, all subject to lender guidelines and full file review, look like this:
- Ceiling: 70% CLTV, with no higher tier on an investment property.
- Credit: a 700 minimum on the investment line.
- Line size: $25,000 to $500,000. Lines above $500,000 exist only on primary residences.
- DTI: 50% maximum, qualified on the interest-only payment calculated on the maximum draw.
- Valuation: lines at or below $500,000 ordinarily use an automated valuation, though you can request a full appraisal. A full appraisal is required above $500,000.
- Draw at closing: at least 75% of the line is drawn at closing, and the pricing floats through both the draw and repayment periods and never converts to fixed.
That last item surprises people. This is not a standby line you open and leave untouched. If you only need a small amount, a line sized to that need fits better than a large one with most of it funded on day one.
For comparison, primary residences and second homes sit on a higher ladder. A primary residence can reach 90% CLTV, but only at a 720-or-better credit profile and up to $500,000. Second homes reach the same 90% only at 720 or better. Those figures do not apply to a rental, so do not let a headline ceiling in an advertisement stand in for your own.
Why a Ranked List Misleads (and What Replaces It)
A list of providers sorts lenders by one yardstick, usually the advertised terms. Your offer differs from the advertised one because the lender prices your credit, your CLTV, your occupancy, and your property type. The best program for your situation might be a lender no list features, and a lender at the top of a list may not write rentals at all.
Of those that write them, some cap leverage tightly and some count DTI strictly. A broker shops several wholesale lenders and matches the file to the one whose guidelines fit it.
This network works through two wholesale HELOC programs, and their terms differ:
- The higher-leverage program is a standalone line, in first or second lien position, with a 3-year interest-only draw and a 17-year repayment. It allows combined exposure of up to $2,000,000 across a borrower’s lines.
- The longer-runway program is also a standalone line, with a 5-year interest-only draw and a 25-year repayment. It carries stricter tradeline requirements and caps combined exposure at $750,000. It also runs every investment-property line.
A quoted figure always belongs to one program’s structure. If a number in a letter does not say which draw and repayment pattern it assumes, ask.
1. Which occupancy does the line treat this property as: primary, second home, or investment?
2. What CLTV ceiling applies to that occupancy at your score?
3. Is title in your name or a revocable trust?
4. How many financed properties do you own, and how many lines do you already carry?
5. What draw is required at closing, and what is the minimum draw afterward?
6. Does the valuation run automated or by full appraisal?
Availability matters too. These HELOC programs run only in the 16 states where Lendmire offers full-service lending, which is narrower than its 41-market DSCR footprint. A broker can confirm quickly whether your property’s state is covered.
Where the General Rule Breaks
The general rule is that a HELOC lends on your equity and your credit. These edge cases bend it.
An LLC-held rental. The line requires title in an individual’s name or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change before a line, or a DSCR cash-out refinance instead, which can lend to an LLC subject to program eligibility.
A score between 600 and 699. The investment line starts at 700. Lower scores fit primary-residence lines with tighter CLTV tiers, so the same borrower may qualify on a home but not on a rental.
Larger portfolios. A borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible. Anyone with a large portfolio should check both limits before applying.
Property type. Single-family, 2-4 unit, PUD, townhome, and condominium properties are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not eligible on either program. On an investment line, the 700 minimum score applies to every eligible property type.
A property listed for sale. In several states, a property listed for sale, or listed within the previous 60 days, is ineligible. Pull a listing before you apply if you are weighing a sale.
Recent credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal on both programs. Foreclosure-family history on an investment file follows a 7-year path for a foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale.
Fixed-rate conversion. NerdWallet notes that some lenders offer fixed-rate options as a market-wide feature. On these network programs, pricing floats and never converts to fixed.
One more point on documents. Whether consumer HELOC disclosure rules apply to a loan on an investor-owned rental depends on the purpose of the credit. Credit extended primarily for a business purpose is generally treated as exempt from those rules. Your letter may look different from a standard homeowner’s, so do not assume it carries every consumer protection.
HELOC or DSCR Cash-Out Refinance?
A HELOC qualifies you. A DSCR cash-out refinance qualifies the property. The choice usually comes down to which of those two is stronger for you.
| Factor | HELOC (investment) | DSCR cash-out refinance |
|---|---|---|
| Reviewed on | Your credit and DTI | Rent covering the payment |
| Title | Individual or revocable trust | LLC possible |
| First mortgage | Stays in place | Replaced by new first lien |
| Leverage | Up to 70% CLTV | Around 75% LTV, standard rental |
| Size | $25,000 to $500,000 | Up to $3,000,000 on standard programs |
The cash-out refinance also carries its own conditions. Programs commonly expect about 6 months of seasoning, and most want a credit score around 660, with 700+ unlocking the strongest leverage tiers. A 1.00 coverage ratio is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA, which is the full monthly housing payment.
Clearing 1.00 does not mean the property is cash-flowing. The ratio compares rent to the housing payment only. Repairs, vacancy, management, utilities, and capex sit outside it.
Two scenarios show how the decision tends to go:
- Picture an investor with a strong score, a revocable trust holding a single-family rental, and a first mortgage that leaves modest headroom. A line sized to a specific purchase down payment can fit well. The first mortgage stays untouched, and the line is a short-term source of funds.
- Consider an investor whose rentals sit in LLCs, with a score near 680 and a larger portfolio. The investment HELOC probably does not fit on title, score, or both. A DSCR cash-out refinance, which looks at the rent, is the more natural structure.
For the full program picture, the complete DSCR loans guide lays out how the rent-based path works end to end.
What the Investor Decision Looks Like in Practice
Start with the purpose of the money. A line works best as a bridge for a defined project, such as a down payment, because the payment moves with the index and steps up at repayment. A refinance fits better when the money will sit in the property for years.
Then stress-test the step-up. Interest-only payments during the draw period are the most affordable the line will ever be. The much larger monthly bills after the draw period can be a rude awakening. On the investment line, the 5-year draw is followed by a fully amortizing 25-year repayment, so model the payment after year five, not the one in year one.
Think about the lien order, too. A new lender looks at every lien on the property. Opening a line before a planned refinance can complicate that refinance, so tell your broker both plans up front.
Last, keep the draw rule in mind. After the 75% closing draw, the longer-runway program sets a $1,000 minimum on later draws. You will be carrying most of the line from the start, so size it to what you will use.
Frequently Asked Questions
Does a HELOC offer letter tell me which provider is best?
No. The letter lists one creditor’s terms, such as the limit, index and margin, caps, and draw and repayment lengths. It does not compare anyone else. To compare, ask a broker for terms from several wholesale lenders on the same property and credit profile, and line up the draw structure, caps, and fees side by side.
Can an LLC borrow on an investment-property HELOC?
Not on these programs. Title must be held by the individual borrower or an inter vivos revocable living trust, and LLCs, corporations, and partnerships are not eligible. If the property is already in an LLC, the choices are a vesting change or a DSCR cash-out refinance, subject to program terms.
What is the highest CLTV on a rental?
On an investment property, the network ceiling is 70% CLTV, with a 700 minimum score and a $500,000 maximum line. Higher figures you may see apply to primary residences or second homes. The 90% tier exists only at a 720-or-better credit profile on those occupancies.
Do I have to draw the whole line?
No, but you must draw at least 75% at closing, a rule that applies to every investment-property line and to both network programs. After that, the longer-runway program sets a $1,000 minimum on later draws. Because pricing floats and never converts to fixed, size the line to the amount you will actually use.
When does a DSCR cash-out refinance make more sense?
It tends to fit when the property is held in an LLC, when your credit is below the investment HELOC floor, or when the file needs property-rent-based lender review. It replaces the first mortgage, so compare it against what you would give up. Eligibility review depends on lender guidelines, the property, and your credit.
