The Quick Read: The lender sizes an investment-property line on the full credit limit you request, not the amount you plan to draw, and across Lendmire’s wholesale network that limit has to fit under a 70% combined loan-to-value ceiling on an investment property, a $500,000 maximum line, and a 700 minimum credit score, all subject to lender guidelines. Planning to use only part of the line does not shrink the test. Requesting a smaller limit does.
- The ceiling on an investment-property line is 70% combined loan-to-value (CLTV), and a credit score above 700 does not raise it.
- Maximum line = property value × 70%, minus every lien already on the property, then trimmed by the $500,000 cap.
- At least 75% of the line is drawn at closing, so a plan to draw only part of the line does not fit this structure.
- Title must sit with you personally or in a revocable living trust. An LLC cannot hold it. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The Short Answer: The Limit Counts, Not the Draw
A lender has to underwrite the most you could borrow, because a line of credit lets you borrow up to the limit whenever you want. So the test uses the whole limit.
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.
Say you plan to use only a slice of the line for a renovation. The lender still adds the full limit you request to your existing mortgage balance. Then it divides by the property value. If that ratio clears the ceiling, the line is sized. If it does not, the limit comes down.
Rental properties get less than your own home does. NerdWallet notes that an investment-property line is possible but comes with a smaller pool of lenders and a lower borrowing amount than a primary-home line, because lenders see higher default risk. Market surveys vary on how much lower. Experian reports that lenders typically cap investment-property lines at 80% loan-to-value. That is a market-wide figure, not this network. On Lendmire’s network, an investment-property line tops out at 70% CLTV.
How the Line Gets Sized
Sizing a line takes four steps. Each one can shrink the answer.
1. Value the property. On an investment line, value usually comes from an automated valuation rather than a full appraisal.
2. Add up the liens. That means your first mortgage balance plus any other secured debt, plus the limit you request.
3. Apply the ceiling. On an investment property across this network, the total cannot exceed 70% of value.
4. Apply the other caps. The dollar maximum, your credit score, and your debt load can each cut the result further. The usable line is the smallest of them.
Run the numbers with percentages. Picture a rental where the first mortgage equals 50% of the property’s value. The ceiling is 70%, so the line can use at most the remaining 20% of value. Ask for a limit above that, and the lender will not approve it as requested. Ask for less, and the test uses your smaller number.
Now picture a rental with almost no debt on it. Seventy percent of a high value could land above $500,000. In that case the dollar cap binds before the percentage does, and the maximum line stays at $500,000.
The third case is the opposite. A rental with a heavy first mortgage may leave only a sliver under the 70% ceiling. If that sliver falls below the $25,000 minimum line size, there is no line to open. That property needs a different structure.
The CFPB’s HELOC booklet describes the same basic logic. A lender applies a percentage to the home’s value and subtracts what you owe on the mortgage. It uses 75% only as an illustration, not as a program rule. The ceiling that applies to you is the one your lender sets for your occupancy type.
What Planning a Partial Draw Changes on This Network
Here is the catch for anyone who wants a large limit but a small draw. On Lendmire’s network, at least 75% of the line is drawn at closing. You cannot open a big line as a standby cushion and leave most of it untouched.
That rule changes how you should think about the plan. Match the limit to what you actually need on day one. If you want to draw only part of the line, the structure does not fit. A smaller line sized to your real need does.
Three more mechanics matter for partial-draw planning.
Qualification uses the maximum draw. The lender reviews your file on the interest-only payment calculated as if you had drawn the full limit. A lower planned draw does not help your debt-to-income math. The maximum allowed ratio is 50%, and a ratio above 45% requires a credit score of at least 680, which an investment line’s 700 floor already satisfies.
The draw period is five years, interest-only. It is followed by a 25-year fully amortizing repayment. That is the only structure offered on investment properties. The shorter 3-year draw option exists only on primary residences and second homes.
Pricing floats and never converts to fixed. It floats through both the draw period and the repayment period. A line used as a long-term funding source carries that exposure for its whole life.
For later draws after closing, the usual minimum is $1,000.
The Caps That Trim the Number
Equity is not the same as borrowing power. Several limits sit on top of the 70% ceiling.
- Credit. The minimum score on an investment line is 700. Both the 720 and 700 tiers reach the same 70% CLTV, so a higher score buys eligibility, not leverage. Sub-700 profiles do not qualify on an investment property. The report must be no more than 90 days old at closing, with no rescores.
- Line size. Lines run from $25,000 to $750,000 overall, but a line above $500,000 is primary-residence only. Investment lines cap at $500,000 no matter how much equity you hold.
- Exposure. A borrower is limited to three lines, with combined exposure capped by the lender. An investor who owns more than 15 financed properties is not eligible.
- Valuation. Because an investment line cannot exceed $500,000, it sits in the automated-valuation lane and commonly closes without a traditional appraisal. A higher CLTV request may trigger a second valuation, and you can request a full appraisal if you want one.
- Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure follows a 7-year seasoning path, and a deed-in-lieu, pre-foreclosure, or short sale follows 4 years.
These lines are available only in the 16 states where Lendmire offers full-service lending. That is narrower than the 41-market DSCR footprint. Every figure here is subject to lender guidelines and full file review.
Rental income does not drive this qualification. A line like this qualifies you personally on credit, debt-to-income, and equity. That is the sharpest difference from a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Who Cannot Use One (Even With Plenty of Equity)
Title is often where an investor’s file stops. The property must be held in fee simple or leasehold 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. If your rental already sits in an LLC, you would need a vesting change. The other path is a DSCR cash-out refinance, which can lend to LLC-titled borrowers subject to lender program eligibility.
Property type is the second filter. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums (including non-warrantable condos) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agricultural zoning are not eligible. Modular factory-built homes are accepted on only one of the two structures the network places, and that structure is not the investment-property one.
Listing status can also block a file. In several states, a property listed for sale, or listed within the past 60 days, is ineligible.
Some banks and credit unions simply do not lend on rentals at all, which is why lender supply is thin. Experian says not every lender offers these lines and that they are generally harder to qualify for than a primary-home line.
Investment HELOC vs. Primary-Home Line vs. DSCR Cash-Out
This table shows why the same equity gives three different answers.
| Factor | Investment-property HELOC | Primary-home HELOC | DSCR cash-out |
|---|---|---|---|
| Reviewed on | Your credit, DTI, equity | Your credit, DTI, equity | Rent vs. PITIA |
| Leverage ceiling | 70% CLTV | Up to 90% CLTV, only at 720+ | About 75% LTV; 70% on short-term rentals |
| Maximum amount | $500,000 | $750,000 | Roughly $100K to $3M |
| Title | Individual or revocable trust | Individual or revocable trust | LLC allowed, per program terms |
| Pricing | Floats, never fixed | Floats, never fixed | Fixed structures available |
In that table, DSCR means debt service coverage ratio. It compares a property’s monthly rent to its full monthly obligation, known as PITIA (principal, interest, taxes, insurance, and association dues). Clearing the coverage test is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
For cash-out files, most programs on the network expect about 6 months of seasoning, meaning you have owned the property for that long. Credit floors run as low as 620 in parts of the network, with most programs wanting about 660 and 700+ unlocking the strongest leverage tiers. Coverage of 1.00 is where select programs start, and stronger ratios open better terms. A separate select-lender path goes below 1.00 with leverage and terms adjusted. Lendmire’s complete DSCR loans guide walks through those tiers in full.
Using your primary home’s equity instead is a different calculation with a higher ceiling. Check your line’s terms first. A CFPB brochure notes that a lender may reduce your limit if your home’s value drops, and some line agreements restrict renting out the home.
The Risks of a Partial-Draw Plan
A line sized to your plan still carries real exposure.
Variable pricing. The CFPB’s HELOC booklet says these lines typically carry variable pricing rather than fixed. On a thin-margin rental, a rise in pricing flows straight into your monthly cost. Stress-test your plan against a meaningful increase before you sign.
The payment step-up. During the 5-year draw period you pay interest only. When repayment begins, the balance amortizes over 25 years and the payment jumps. Plan for that step well before it arrives.
Personal liability. The CFPB describes a HELOC as an open-end line you can borrow against repeatedly, and warns that you could lose your home if you cannot repay. A rental line is a personal obligation, not a non-recourse rental loan.
Lien position. A standalone line can sit in first or second lien position. That flexibility helps free-and-clear rentals, but a second-lien line sits behind your existing mortgage and shares any value decline with it.
Equity is not cash flow. Borrowing against a rental adds a payment to the property. If the rent does not comfortably support both obligations, the extra line becomes a strain rather than a tool.
Sizing the Request: A Practical Approach
Start from the plan, not the maximum. Work through these questions in order.
1. What will the money do? Define the use (a renovation, a down payment on the next rental, reserves) and put a number on it.
2. What is the property’s likely value? Expect an automated valuation, which may not reflect a recent rehab.
3. What do you owe? Total every lien. Your first mortgage balance is the starting point.
4. What room does 70% leave? Subtract total liens from 70% of value. That is the ceiling for your limit.
5. Does the result clear $25,000? If the room is smaller than the line minimum, the product does not fit this property.
6. Does your plan match the 75% draw-at-closing rule? If you need only a fraction of the limit, shrink the limit.
7. Can you carry the full limit? The lender reviews your file on the maximum draw, so make sure your debt-to-income works at that level.
Investors who want more leverage than 70%, or who hold property in an LLC, usually look at a DSCR cash-out refinance instead.
Key Terms Defined
Combined loan-to-value (CLTV): All secured debt on a property, including the new line’s limit, divided by the property’s value.
Draw period: The stretch when you can borrow from the line. On an investment property, that is 5 years of interest-only payments.
Repayment period: The stretch after the draw period when the balance amortizes. On an investment line, it runs 25 years.
Lien position: Where a loan ranks for repayment if the property is sold or foreclosed. First lien is paid before second lien.
Automated valuation: A computer-generated property value that stands in for a traditional appraisal on smaller lines.
Vesting: How title to the property is held, whether by you personally, a trust, or an entity.
Frequently Asked Questions
If I only plan to draw part of the line, can I ask for a bigger limit anyway?
You can ask, but the lender tests the full limit, not your plan. On Lendmire’s network, at least 75% of the line is drawn at closing, so a large limit with a small draw does not fit. Size the limit to the amount you actually need.
Does a higher credit score raise how much I can borrow on a rental?
Not on an investment property in this network. Both the 720 and 700 tiers reach 70% CLTV, and 700 is a hard floor. A stronger score may help your overall file, but it does not lift the ceiling. Primary-residence lines work differently, reaching 90% CLTV only at a 720-or-better profile.
Can I use a HELOC on a rental held in an LLC?
No. Title must sit with you individually or in an inter vivos revocable living trust, so LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold it. A property already deeded to an LLC would need a vesting change. The alternative is a DSCR cash-out, subject to lender program eligibility.
Will the lender order a full appraisal?
Usually not. An investment line cannot exceed $500,000, and full appraisals begin only above that, so these lines ordinarily run automated valuation. A higher CLTV request may call for a secondary valuation. You can also ask for a full appraisal, which can help if you recently improved the property.
How is this different from a DSCR cash-out refinance?
The line qualifies you personally on credit, debt-to-income, and equity, with a 70% CLTV ceiling and a $500,000 cap. A DSCR cash-out qualifies primarily on property-level rental income covering the payment, with leverage around 75% LTV on a standard rental, subject to lender guidelines.
