The Quick Read: It depends on your first mortgage, because on Lendmire’s network the first loan balance plus the full new line cannot exceed 70% of the property’s value, and the line itself tops out at $500,000. The smaller of those two limits sets your number. Your debt-to-income ratio can set it lower still.
- The ceiling on an investment property is 70% combined loan-to-value (CLTV), whether the line sits in first or second position.
- The line runs from $25,000 to $500,000. A line above $500,000 is not available on an investment property.
- A 700 credit score is the floor. A 720 score unlocks no extra leverage on a rental.
- Title must sit in your own name or a revocable living trust. An LLC cannot hold it.
- The product is offered only in Lendmire’s 16 full-service states, which is narrower than its DSCR footprint. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
How Is the Second-Position Limit Calculated?
The maximum line is 70% of the property’s value minus your existing first mortgage balance, capped at $500,000. Lenders measure it as CLTV: the first mortgage plus the full new line, divided by the property’s value. Wall Street Prep states the same formula as total secured loan balance divided by appraised value.
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.
Three limits apply, and the smallest one wins:
1. The CLTV room. This is 70% of value minus what you owe on the first lien.
2. The program dollar cap. An investment line cannot exceed $500,000.
3. Your debt-to-income capacity. The maximum is 50%, calculated on the interest-only payment at the maximum draw.
A second-position line sits behind your existing mortgage. The CFPB describes a HELOC as an open-end line of credit that lets you borrow repeatedly against equity. Its HELOC booklet shows the standard sizing method: the lender takes a percentage of the home’s value and subtracts what you owe. The 70% ceiling is the percentage on this network’s investment tier.
What does the room look like at different first-lien levels?
The table expresses the room as a share of the property’s value. Multiply by your own appraised or estimated value to see the dollar figure. Then check it against the $500,000 cap.
| First mortgage, as % of value | Room under 70% CLTV |
|---|---|
| 30% | Up to 40 points of value |
| 45% | Up to 25 points of value |
| 60% | Up to 10 points of value |
| 70% or higher | None |
The last row matters most for recent buyers. An investor who bought at 75% to 80% LTV on a purchase has no room under a 70% ceiling. The first mortgage already sits above it. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
The best-fit file has a low first mortgage and a long ownership history. That investor keeps the existing first loan in place and adds a line behind it.
Does the Full Line Count, or Only What You Draw?
The full line commitment counts, not just the drawn balance. If you request a $200,000 line and draw $50,000, the CLTV test still uses the $200,000. Size the request to the room you actually have.
A mortgage glossary shows how much this matters. In its illustration, the same debt reads 66% on the drawn balance and 77% on the full line. That is an illustration of the concept, not a program figure, but it shows why a borrower who counts only the draw can overshoot the ceiling.
A second structural point affects planning. On this network, at least 75% of the line is drawn at closing. The line is not a standby reserve you leave untouched. You start paying interest on most of it right away.
What Else Sets Your Ceiling Besides Equity?
Equity is one test. The borrower and the property must pass the others.
- Credit. The minimum is 700, with no tier below it. The report must be no more than 90 days old at closing. The score model uses one bureau, keyed to the primary wage earner.
- Income and DTI. A HELOC is underwritten on the borrower’s personal credit and debt-to-income, not on rental coverage. Maximum DTI is 50%.
- Title. Fee simple or leasehold held by an individual or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
- Property type. Single-family, 2-4 units, PUDs, townhomes, and condos are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned property are not offered.
- Exposure. A borrower can hold up to three lines. Combined exposure on the program that writes investment lines caps at $750,000. A borrower who owns more than 15 financed properties is not eligible.
- Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On an investment file, a foreclosure seasons for 7 years. A deed-in-lieu, pre-foreclosure, or short sale seasons for 4.
- Valuation. Because an investment line cannot exceed $500,000, it ordinarily runs on an automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation, and a borrower can request a full appraisal at any point.
Everything above is subject to lender guidelines and full file review. It is not a commitment to lend.
Why does a higher credit score not raise the amount?
On an investment property, the credit table has two tiers. A 720 profile and a 700 profile both reach 70% CLTV up to $500,000. Credit above 700 buys no extra leverage on a rental.
Primary residences and second homes work differently. Those lines can reach 90% CLTV, and that tier exists only at a 720 or better credit profile. Do not carry that figure over to a rental.
Occupancy also decides which table applies. Rental income, regular bookings, or a management agreement can recharacterize a second home as an investment property. The 70% ceiling then applies.
Key Terms Defined
Combined loan-to-value (CLTV): the total of every loan secured by the property, including the full new line, divided by the property’s value.
Second position: a lien that is paid after the first mortgage if the property is sold or foreclosed.
Draw period: the stretch when you can borrow from the line and pay interest only. On an investment line it runs 5 years, then a 25-year repayment period follows.
Vesting: the legal form in which title is held, such as an individual name or a revocable living trust.
Debt-to-income (DTI): your monthly debt payments divided by your monthly income, measured here on the interest-only payment at the maximum draw.
Automated valuation: a model-based value estimate used in place of a full appraisal on smaller lines.
How Does This Compare With the Broader Market?
Investment-property HELOCs are a narrow product everywhere. NerdWallet reports that the lender pool is smaller than for primary-home lines, the borrowing amount is lower, and some lenders require multiple appraisals. It also cites at least 20% equity as a market requirement and a typical 10-year draw at banks.
The network figures differ. On Lendmire’s network, an investment line needs 30% equity, because the ceiling is 70% CLTV. The draw is 5 years rather than 10. Treat market figures as a reference point for what a bank might offer. Treat the network figures as the ones that apply here.
The line also floats and never converts to a fixed structure. That is a real difference from a cash-out refinance. Budget for a payment that can move.
When Second Position Is the Wrong Tool
A second-position line fails in a handful of predictable setups. Each has an alternative.
The first mortgage is already high. If the first loan plus the line would exceed 70%, request a smaller line. You can also pay down the first mortgage first, or move to a cash-out refinance that replaces it.
The rental sits in an LLC. The HELOC is blocked. You can re-vest title, which can create other issues with insurance, lenders, and liability. You can also borrow against equity in a property you hold personally. Or you can use a DSCR cash-out refinance, which can be made to LLC borrowers subject to lender program eligibility.
Credit is below 700. No HELOC tier exists below 700 on an investment property. DSCR cash-out is the usual alternative. A 620 credit floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers.
You need more than $500,000. The investment cap blocks it. DSCR loans run up to $3,000,000 on standard programs (smaller balances available through select lenders), and above $2,500,000 the network generally holds to 30-year fixed structures.
You hold many financed properties. Personal DTI can limit a borrower with heavy existing debt, and a borrower with more than 15 financed properties is ineligible. A DSCR loan is reviewed on the property’s rent against its payment, so it fits that investor better.
How does a DSCR cash-out refinance differ?
| Factor | HELOC, second position | DSCR cash-out refinance |
|---|---|---|
| Underwritten on | Personal credit and DTI | Property rent vs. payment |
| Max leverage | 70% CLTV, investment | About 75% LTV, standard rentals |
| Max size | $500,000 | Roughly $3,000,000 |
| First mortgage | Stays in place | Replaced by the new loan |
| Title | Individual or revocable trust | LLC possible, per program terms |
A cash-out on short-term-rental collateral tops out at 70% LTV, and the 75% figure applies to standard rentals. Most cash-out files expect about 6 months of seasoning on a recent purchase. Reserves vary by lender, leverage, loan size, and transaction type. About 6 months of PITIA is common, and conservative rate-and-term files at modest leverage can see reserves waived.
Across the wholesale network, 1.00 is where many select programs start for DSCR coverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger coverage opens better leverage.
One caution on reading the ratio. DSCR compares rent to principal, interest, taxes, insurance, and any association dues. Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside that calculation.
The tradeoff is simple. A HELOC keeps a low-balance first mortgage intact but floats and is limited to $500,000. A cash-out resets the whole loan but sizes on the property. Lendmire’s complete DSCR loans guide covers the cash-out side in detail. If your bank has already turned you down, the piece How to Qualify for an Investment Property HELOC When Banks Won’t Do Second Position covers that situation.
Common Mistakes
Counting only the drawn balance. The full commitment goes into the CLTV test, as shown above.
Assuming 80% to 90% like a primary home. The 90% tier belongs to primary residences and second homes at a 720 or better profile. An investment property stops at 70%.
Treating the HELOC as a first-lien tool on an LLC deed. The title rule is a hard gate. Check vesting before you collect any other documents.
Stacking debt without checking what is left. A second lien reduces your remaining equity cushion. Run the combined math before you borrow twice against one property.
Ignoring condo and association details. Condo collateral is eligible, including non-warrantable condos, but it has its own wrinkles.
Planning no exit. A line draws interest-only for 5 years and then amortizes over 25. Know before you draw how you will pay it down or refinance it.
What to Collect Before You Ask
A clean file starts with five items:
1. The vesting deed, to prove title is in your name or a revocable trust. 2. The current first-mortgage statement, to confirm the balance. 3. The insurance declaration for the property. 4. A realistic value estimate, so you know your CLTV room before applying. 5. Your credit and debt picture, to test the 700 floor and the 50% DTI limit.
Frequently Asked Questions
What is the maximum CLTV on an investment property HELOC in second position?
It is 70% CLTV on an investment property. That means the first mortgage balance plus the full new line cannot exceed 70% of the property’s value. The same ceiling applies whether the line sits in first or second position. Primary residences and second homes can reach 90% CLTV, but only at a 720 or better credit profile, and that tier never applies to a rental.
What is the largest line I can get on a rental?
The cap is $500,000, and the minimum is $25,000. Lines above $500,000 are available only on primary residences, not rentals. Your actual limit is whichever is smaller: the CLTV room left after your first mortgage, the $500,000 cap, or what your debt-to-income allows.
Does a 720 credit score get me a bigger line than a 700?
Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
No. Both reach 70% CLTV up to $500,000 on an investment property. A higher score buys extra eligibility on primary and second-home lines, not extra leverage on a rental. Seven hundred is the floor, and no tier sits below it.
Can my LLC take the line?
No. Title must be held by an individual or a revocable living trust. If the property is already in an LLC, the options are a vesting change or a DSCR cash-out refinance, which can be made to LLC borrowers subject to lender program eligibility.
Do I need a full appraisal?
Usually not. Lines at or under $500,000 ordinarily run on an automated valuation, and every investment line falls in that range. A higher CLTV may trigger a secondary valuation, and you can request a full appraisal in any case.
