The Quick Read: An investment-property line tops out at 70% combined loan-to-value, minus what you already owe. On Lendmire’s wholesale network the line is capped at $500,000 in total, and the minimum credit score is 700. The draw runs five years interest-only before a 25-year repayment period begins. For that reason the draw structure shapes your real borrowing capacity as much as the cap does.
- The ceiling on an investment property is 70% combined loan-to-value (CLTV). A 720 score and a 700 score reach the same ceiling.
- Your existing first mortgage counts against that 70%. Only the remaining slice of value can become a line.
- Line sizes run from $25,000 to $750,000 across the network, but an investment line stops at $500,000.
- At least 75% of the line is drawn at closing. “Borrow only what you need” does not apply here.
- The property must be titled in your personal name or a revocable living trust. An LLC cannot hold title on this product.
How the Maximum Line Is Calculated
The maximum line is the property’s value times the lender’s CLTV cap, minus every lien already on the property. The lender sets the cap. No federal rule sets it, and it moves with occupancy type and credit profile.
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.
Start with value. On an investment line of $500,000 or less, the lender ordinarily orders an automated valuation instead of a full appraisal. A higher CLTV may call for a second valuation, and a borrower can always ask for a full appraisal. One BiggerPockets investor describes the same pattern in his account of using HELOCs to build wealth: an appraisal is typically needed, but not on every line.
Next comes the combined test. The lender adds the existing first mortgage and the new line, then compares the total to value. The sum has to stay at or under the cap.
The formula is simple: value × CLTV cap − existing liens = the most you can borrow. Three limits then trim the result. The first is the dollar ceiling on the product. The second is the minimum line size. The third is your debt-to-income ratio, which is covered below.
What Is the Cap on an Investment Property?
On an investment property, the network ceiling is 70% CLTV, and the maximum line is $500,000. The minimum credit score is 700. Investment is a two-tier table, so a 720 score buys nothing extra on leverage.
Here is how the pieces fit together on a typical wholesale placement:
- Leverage: 70% CLTV on an investment property at either credit tier, subject to lender guidelines.
- Line size: $25,000 to $500,000 on an investment property. The $750,000 top of the broader range, which reaches only primary residences, is not available on a rental.
- Credit: 700 is a hard floor. No tier sits beneath it for investment collateral. The score comes from a single bureau, keyed to the primary wage earner, and the report can be no more than 90 days old at closing.
- Debt-to-income: 50% maximum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to use.
- Position: a standalone line in first or second lien position.
- Exposure: a borrower is limited to three lines, and a borrower with more than 15 financed properties is not eligible.
These are select-network guidelines, not promises. Every file is reviewed individually, and Lendmire is the broker arranging the placement, not the lender. This line is offered only in Lendmire’s 16 full-service states. That is narrower than the 41-market footprint for DSCR loans, which covers 40 states plus Washington, D.C.
Lenders set different caps. A credit union may go higher on leverage and lower on dollars, so compare the full structure instead of one headline number. A line that looks generous on percentage can turn out smaller on the dollar limit.
Three Sizing Scenarios
Most of the leverage is spent before you apply. The ceiling is 70% of value across all liens, so your current mortgage decides how much room remains. These examples use percentages of value, because the calculator handles dollars.
A rental with a first mortgage at 50% of value. The ceiling is 70%, so up to 20% of value is available as a line, subject to the other limits. This is the comfortable case.
A rental with a first mortgage at 65% of value. Only 5% of value is left. On a modestly priced property, that slice can fall below the $25,000 minimum line, and then there is no product at all. On a higher-priced property, it may clear the minimum but yield a small line for the work required.
A rental with no mortgage. The line can reach 70% of value, then the $500,000 ceiling applies. The dollar cap only bites on higher-value properties. On a lower-value rental, the percentage is the binding limit.
Notice what is not in any of these examples: your rent. A HELOC on a rental is underwritten mainly on your credit, your debt-to-income ratio, and the equity. The property’s rent does not set the line. This is the structural difference from a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Because the line is underwritten on you, every other loan you carry counts. A landlord with several financed properties may find the 50% debt-to-income test binds before the CLTV cap does.
Draw Terms: What Five Years Interest-Only Really Means
An investment line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. During the draw you can borrow, repay and re-borrow. After it ends, the draw closes and the payment includes principal.
Pricing floats through both phases on this product. It never converts to fixed. Rates are not quoted here, but the payment can move with the market even if your balance stays flat.
Consumer-grade lines usually run longer in the draw phase. Experian reports that draw periods typically run five to 10 years, followed by a 20-year repayment period, and notes that some lines end in a balloon payment. The BiggerPockets HELOC glossary gives a specific example within that range: a 10-year draw and 20-year repayment.
| Feature | Investment line (5/25) | Common consumer norm | Primary/second-home option (3/17) |
|---|---|---|---|
| Draw phase | 5 years, interest-only | 5-10 years | 3 years, interest-only |
| Repayment phase | 25 years | About 20 years | 17 years |
| Payment at draw end | Steps up | Steps up | Steps up sharply |
| Available on rentals | Yes | Varies | No |
The 3-year draw with a 17-year repayment is a higher-leverage structure that exists only for primary residences and second homes. It does not apply to investment property. Investors should not assume it is on the menu.
What does a shorter draw mean for sizing? The long repayment keeps the amortizing payment smaller than it would be on a 17-year schedule. The cost is that the draw window closes in five years, so any plan that depends on re-borrowing needs to fit inside it.
The required draw also matters. At least 75% of the line is drawn at closing. After that, each additional draw must be at least $1,000. If you wanted a standby line you rarely touch, this product is the wrong tool. You will be paying interest on most of it from day one.
Stress-Testing a Draw Against Rent and Vacancy
A draw is only as safe as the rent behind it. Landlords should size the line against the repayment phase, not the draw phase. During the draw the payment is interest-only and comfortable. In repayment it rises, and the consumer-finance side of the system is blunt about it.
The CFPB’s explainer on home equity lines warns that payments are often significantly higher once repayment begins and that some plans demand the whole balance at that point. The agency’s HELOC booklet adds the risk that matters most for a landlord: you could lose the collateral if you cannot repay. When the collateral is a rental, that means the rental.
A practical stress test has four steps:
1. Take the rent the property collects today.
2. Subtract a vacancy cushion, repairs, management and utilities. These sit outside any lender ratio but inside your actual cash flow.
3. Compare what remains to the repayment-phase payment on the full line, not just the drawn amount.
4. Repeat with the payment moved higher, because pricing floats.
If the property still carries the line after step four, the draw is sized sensibly. If it only works at the interest-only payment, the line is a bridge, and you need a dated plan to refinance or pay it down before the draw ends.
Two common exits exist. One is paying the balance from a sale or a stabilized-rent refinance. The other is refinancing into a fixed-payment home equity loan before the draw ends, an option Experian lists. For a landlord with a stabilized property, the natural exit is often a rent-based cash-out refinance, discussed below.
A bridge strategy works best when the improvement itself lifts rent. A value-add rehab that raises the lease and lets you refinance within the draw window fits this line. A plan that needs five years of unchanged rent and no vacancy to service the repayment does not.
Who Cannot Use This Line
Title is the sharpest filter. The line is available only for property held in the individual borrower’s name or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded into an LLC needs a vesting change first, or it belongs in a different product.
Property type is the next filter. Eligible types include single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agriculturally zoned properties are not offered.
Credit history matters too. A bankruptcy needs four years of seasoning from discharge or dismissal. A foreclosure on an investment file follows a 7-year seasoning path, and a deed-in-lieu, pre-foreclosure or short sale follows a 4-year path.
Portfolio size is the final filter. Three lines per borrower is the limit, and more than 15 financed properties disqualifies the borrower. A landlord above those limits, or one whose properties sit in entities, needs to look at rent-based products instead.
Some states shorten the repayment runway on this product, and a few apply credit-based CLTV caps or listing restrictions. The standard structure above is the starting point, and a broker confirms the state-level version before you plan around it.
HELOC or DSCR Cash-Out?
For a landlord, the real question is often which tool fits, not how much a HELOC allows. A HELOC is a revolving, floating-price line underwritten on you. A DSCR cash-out refinance is a lump sum underwritten on the property’s rent coverage.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Underwriting basis | Your credit, DTI, equity | Rent vs. PITIA on the property |
| Leverage ceiling | 70% CLTV on an investment property | About 75% LTV on a cash-out |
| Structure | Revolving, floating price | Lump sum, fixed spine |
| Title | Individual or revocable trust | Can be an LLC, subject to program terms |
| Size range | $25,000-$500,000 on investment | Up to $3,000,000 on standard programs |
| Best fit | Short holds, bridge capital | Stabilized, longer-term holds |
A few details sit behind that table. DSCR compares monthly rent to the full monthly obligation of principal, interest, taxes, insurance and any HOA dues. Many select programs start at a 1.00 ratio, and stronger ratios open better pricing and leverage. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Clearing 1.00 does not mean the property has positive cash flow. Repairs, vacancy, management, utilities and capex all sit outside the calculation.
A cash-out refinance also has seasoning, typically around six months. Credit expectations for DSCR files run lower than for the HELOC: a 620 floor exists in parts of the network, most programs want about 660, and 700 or better unlocks the strongest leverage tiers. Extended terms of 40 years and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want them.
The tradeoff is real in both directions. If you hold property in an LLC, own many financed rentals, or want a fixed structure for a long hold, the rent-based path usually fits better. If you hold a rental personally, have strong personal credit and low existing leverage, and want bridge capital for a defined short window, the HELOC can be cheaper and simpler. The complete DSCR loans guide covers the rent-based side from the ground up.
A related path is bank-statement qualification for self-employed owners. On an investment line, though, the 700 credit floor sits above the bank-statement minimum, so that route never becomes the binding limit.
Draw Terms to Get in Writing
Before signing, ask the lender to confirm each of these items in writing:
- The draw length and the repayment length, stated together as one structure.
- The percentage required at closing, and whether the full limit counts in your debt-to-income test.
- The minimum for later draws.
- Whether pricing floats through both phases and what, if anything, caps it.
- What happens at the end of the draw, including any balloon or required payoff.
- Whether the line is in first or second lien position, and how it interacts with your current mortgage.
- Whether a valuation beyond the automated one could be required at your CLTV.
- Any state-specific changes to the draw or repayment period.
- Whether the lender counts the whole line toward your leverage and debt-to-income, even if you never draw it.
One more habit helps. Ask for the repayment-phase payment on the full line at today’s pricing and at a higher price. If the property still carries the debt, the draw terms are sound.
Key Terms Defined
CLTV (combined loan-to-value): the total of all liens on the property divided by its value.
Draw period: the window when you can borrow, repay and re-borrow, usually paying interest only.
Repayment period: the phase after the draw ends, when you can no longer borrow and the payment includes principal.
Interest-only: a payment that covers only the interest on the balance, so the principal does not fall.
DSCR: a rent-to-debt ratio that compares monthly rent to the full monthly obligation on the property.
Revocable living trust: a trust you can change or cancel, which is an eligible way to hold title on this product.
Frequently Asked Questions
Can I borrow 80% of my rental’s value on an investment property HELOC?
Not on this network. The ceiling on an investment property is 70% CLTV, and that figure includes your existing first mortgage. Some lenders elsewhere advertise higher caps, but the network’s number controls any file placed through Lendmire. The dollar cap on an investment line is $500,000.
Does a higher credit score raise how much I can borrow on a rental?
Not above 700. A 720 and a 700 both reach the same 70% CLTV cap on an investment line. Below 700 there is no tier at all, so the score works as a pass-or-fail test for eligibility, not a lever for leverage. Debt-to-income still has to clear, with 50% as the maximum.
Can I use a HELOC if my rental is held in an LLC?
No, not directly. The line requires title in your individual name or in a revocable living trust, and an LLC cannot hold it. A property already deeded to an LLC would need a vesting change, or a rent-based cash-out refinance may be the better route, depending on lender program terms.
Do I pay interest on the whole line even if I use only part of it?
On this product you effectively do on most of it. At least 75% of the line is drawn at closing, so interest runs on that portion from the start. Later draws must be at least $1,000. A landlord who wants an untouched standby line should compare other structures.
What happens to the payment when the draw period ends?
It steps up. Repayment begins on a 25-year amortizing schedule, and the payment now includes principal. Floating pricing means it can also move with the market. Run your rent coverage against the repayment-phase payment on the full line before you take the draw.
Next Step
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. If the property sits in an LLC or you are building a larger portfolio, a rent-based alternative may fit better, and the same conversation covers that. Programs change, every file is underwritten individually, and nothing here is a commitment to lend.
The cap is only part of the question. The harder part is deciding how much of a five-year interest-only window the property can pay back once the draw closes.
