The Quick Read: Usually not on a zero-balance basis: on the investment lines Lendmire’s wholesale network places, at least 75% of the line is drawn at closing, so at most a quarter can sit idle, and lenders set their own terms on a product that is scarce and strict.
- Investment lines in the network cap at 70% CLTV (combined loan-to-value) with a 700 minimum credit score.
- The maximum line on an investment property is $500,000.
- The payment is qualified on the maximum draw, so unused room still counts against your debt-to-income ratio.
- Title must be held personally or in a revocable living trust. An LLC cannot hold it.
- A standby reserve is a better fit for a line on your primary residence than on a rental.
What does “never draw” actually mean?
A standby line is a credit line you open and leave at a zero balance. On a primary residence, that is often allowed. Experian notes that most lines can sit unused, but some lenders require a minimum draw after opening, and the required draw can be as much as 100% of the approved amount.
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.
Rental property changes the picture. Lenders treat rentals as higher risk, so fewer of them offer a line at all. NerdWallet says not every lender offers an investment property HELOC and that the requirements are strict. An investor forum thread, on BiggerPockets, includes a lender comment calling these lines thinner than primary-home lines but not mythical, with a closed-end second or a rent-based second as the usual fallback.
Across the wholesale network Lendmire works with, the investment line is built as a funded product. At least 75% of the line is drawn at closing. Interest runs on that drawn balance from day one. The remaining room, a quarter or less, is a small reserve rather than a standby fund.
So the honest answer is split. Can you get the line? Possibly. Can you get it and leave it at zero? Not on this structure.
How the investment line is built
The structure is simple once you see the pieces. The table below compares the three shapes an equity product can take.
| Structure | Draw at closing | Cost when “unused” | Fit |
|---|---|---|---|
| True standby line | None required | Fees only | Mostly primary homes |
| Partial-draw line | At least 75% (network investment line) | Interest on the drawn part | Investors needing funds now |
| Closed-end second | 100% | Full balance accrues | One-time capital needs |
On the network’s investment line, the details look like this:
- Collateral: a property you already own, never the one you are buying.
- Credit: 700 minimum. The 720 and 700 tiers both reach 70% CLTV, so a higher score adds eligibility cushion rather than leverage.
- Size: $25,000 up to $500,000 on an investment property. Larger lines are primary-residence only.
- Position: first or second lien.
- Draw and repayment: a 5-year interest-only draw period, then a 25-year fully amortizing repayment.
- Pricing behavior: it floats through both periods and never converts to fixed.
- Later draws: a $1,000 minimum after closing.
- Property types: single-family, 2-4 units, PUD, townhome and condominium. Manufactured homes, co-ops, condotels and log homes are not eligible.
Every figure here is subject to lender guidelines and full file review. This is a broker’s summary of ranges, not a commitment to lend.
Why 70% CLTV matters more than the draw rule
The CLTV cap sets how much equity the line can reach. On an investment property, the network ceiling is 70% CLTV, with no higher tier. Equity lines on a primary residence reach further. The ceiling there is 90% CLTV, and it exists only at a 720 or better credit profile.
Investors often see higher leverage figures quoted elsewhere. Those describe the broader market, not this network. One forum commenter, in a BiggerPockets discussion, describes lenders at 60-65% on rentals. Terms vary widely, which is the point. Shop the structure, not the headline.
Think of it this way. Combined leverage counts your first mortgage and the new line together. A rental with a healthy first mortgage may have little room left under 70%. A rental owned free and clear has the most.
Valuation is usually automated. A line capped at $500,000 on an investment property sits below the point where a full appraisal is required, so it commonly closes without a traditional appraisal. That helps cost, but an automated value will not capture a fresh rehab. If you just finished a major renovation, ask whether a full appraisal can be requested.
What happens to the unused room?
The undrawn portion still counts. The network qualifies the line on the interest-only payment calculated on the maximum draw, not on what you actually borrowed. Debt-to-income can run up to 50%, and 45% for credit profiles from 600 to 679. A ratio above 45% needs a 680 minimum, though the investment floor of 700 already sits above that.
Practices differ elsewhere. Some conventional-style underwriting ignores a zero-balance line, and some assigns a calculated payment. Do not assume the generous version. On this structure, plan for the full line to count.
DSCR (debt service coverage ratio) compares monthly rent to the full monthly obligation: principal, interest, taxes, insurance and any HOA dues. A line payment does matter to any other loan that tests DTI.
Two cautions follow:
1. A line’s cash is borrowed money. Some purchase lenders review borrowed down-payment funds differently, so confirm before you count on it.
2. A 1.00 coverage ratio is not the same as positive cash flow. Repairs, vacancy, management, utilities and capital expenses all sit outside the calculation.
Can the lender freeze the line?
Yes, and that is the real weakness of any reserve built on a credit line. A line is not guaranteed money.
The CFPB’s HELOC booklet says plans generally let the lender freeze or reduce the line if the property’s value falls or the borrower’s finances worsen. Those are the moments an investor most needs cash. The Federal Reserve’s HELOC tips add that a lender must give written notice after a freeze or reduction, and cannot charge a fee to reinstate once the cause is gone.
Those consumer protections were written with dwellings in mind. Whether they carry over to a business-purpose rental line depends on the lender’s loan documents, so read the freeze and reduction clause before signing.
The practical lesson is timing. If you want a line as insurance, open it while the property’s value and your finances are strong. Waiting until you need it is the riskiest sequence.
Title and entity rules (the sharpest difference from DSCR)
A DSCR loan lets you hold the rental in an LLC, subject to lender program eligibility. The investment line does not.
Title must be held by the individual borrower, or by 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 first, or a DSCR cash-out refinance instead.
Two other file limits apply. A borrower is limited to three lines, with combined exposure capped on the program. A borrower owning more than 15 financed properties is not eligible.
Availability is narrower than the DSCR footprint. These lines are offered in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA. The DSCR program covers 41 markets, including Washington, D.C. Texas has added conditions on primary residences, but second homes and investment properties are non-homestead transactions there. In several states, including IN, NC, PA, TN, TX and WA, a property listed for sale or listed in the past 60 days is ineligible.
Key Terms Defined
Standby line: a credit line opened to sit at a zero balance until you need it.
CLTV: combined loan-to-value, which adds the first mortgage and the new line together against the property value.
Draw period: the stretch when you can borrow from the line, usually interest-only.
Minimum closing draw: the share of the line the lender requires you to take at closing, which is 75% on the network’s investment line.
DSCR: the ratio of monthly rent to the full monthly obligation on the property.
AVM: automated valuation model, a computer estimate of value used in place of a full appraisal.
Which alternative fits which goal?
When the line’s draw rule or title rule defeats your plan, you have other routes. Match the tool to the goal.
| Option | Best for | Main tradeoff |
|---|---|---|
| Line on your primary residence | True standby reserve | Puts your home at risk |
| Investment property line | Funds you will use soon | 75% drawn at closing |
| DSCR cash-out refinance | LLC-held or larger rentals | Replaces your first loan |
| Closed-end second | One-time capital need | Fully drawn from day one |
The primary-residence line is the real unused-line case. Investors sometimes open one before converting a home to a rental. A BiggerPockets episode covers that sequence of getting the line before the home becomes a rental.
A DSCR cash-out refinance works on different logic. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Across the network, cash-out on a standard rental tops out around 75% LTV, and 70% when the collateral is a short-term rental. Six months of seasoning is the common expectation. Most programs want a score near 660, and select programs start at 1.00 coverage. 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 (principal, interest, taxes, insurance).
The complete DSCR loans guide walks through how those pieces fit together.
Who should choose which path?
The decision comes down to what the money is for.
Consider an investor who owns a rental personally with a lot of equity and wants cash for a renovation within months. The partial-draw structure can fit, because the draw is not wasted. The cost of carrying the balance has to be stress-tested against rent, since the line floats and the interest-only period eventually ends.
Now consider an investor holding rentals in an LLC who wants dry powder. The line is out, because the entity cannot hold title. A DSCR cash-out is the more natural lane. That choice trades flexibility for a larger, fixed-structure loan.
Finally, picture a borrower who wants a pure safety net and owns a home with equity. The primary residence line fits that goal better, though it puts the home as collateral for rental risk. This is a real tradeoff. The investor decides whether protecting liquidity is worth tying the house to the rental business.
Questions to ask before you apply
Use this list with any lender:
- What is the minimum draw at closing, in writing?
- Is the payment qualified on the maximum draw or the actual balance?
- Is there an annual fee, inactivity fee, early-closure fee or per-draw fee?
- What triggers a freeze or reduction, and how will you be notified?
- Does the line stay floating through repayment, or can it convert?
- Is the line accepted on a rental held personally, or must it be in a trust?
- Will an automated value be used, and can you request a full appraisal?
Fee amounts are set by each lender’s contract, so no single published figure applies. Ask for the schedule rather than relying on a general range.

Frequently Asked Questions
Can I open the line and leave the balance at zero?
Not on the network’s investment line, which requires at least 75% drawn at closing. Primary-residence lines are more likely to allow an idle balance, though some lenders still require a minimum draw. Confirm the closing draw in writing before you pay any fees.
Does an unused line count against me when I apply for another loan?
On this structure, yes for any loan that tests DTI, because the payment is qualified on the maximum draw. A DSCR purchase does not test personal DTI, so the line mainly shows up through credit and reserves. Treatment varies by lender and underwriting type.
Can I hold the rental in an LLC and still get the line?
No. Title must be held individually or in a revocable living trust. A property already in an LLC needs a vesting change first. A DSCR cash-out refinance is the usual alternative, subject to lender program eligibility.
What credit score and leverage does an investment line need?
The network minimum is 700, and the ceiling is 70% CLTV on an investment property. Scores of 720 and 700 both reach that ceiling. Primary-residence lines reach 90% CLTV only with a 720 or better profile.
Can the lender shut the line if my property drops in value?
Yes. Lenders can generally freeze or reduce a line when value falls or finances worsen. Read the freeze and reduction clause, and ask how notice is given.
