The Quick Read: Your line size is set by the lowest of three limits: the equity left after your first mortgage, the lender’s combined-leverage ceiling, and the program’s dollar cap. Your credit and debt ratios decide whether you qualify at all. Everything is subject to lender guidelines and full file review.
- On Lendmire’s network, an investment-property line tops out at 70% combined loan-to-value (CLTV) and $500,000.
- Credit must be 700 or better, and 700 and 720 both reach the same 70% ceiling.
- Business owners usually document income through bank statements or full traditional personal-income documentation, and both are full underwriting.
- The line is tested on the borrower, not the rent. A property held in an LLC generally cannot take this product.
A business owner with equity in a rental often asks the same question: how big a line can the property carry? The honest answer is arithmetic first and paperwork second. This guide walks through both.
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.
What Is This Product, Exactly?
You borrow, repay, and borrow again within limits. The rental is the collateral. The money can go to your business, your next purchase, or repairs.
Here is the part that trips people up. A DSCR loan (debt service coverage ratio, meaning rent divided by the full monthly housing payment) qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC works the other way. It tests you: your credit, your debt-to-income ratio (DTI), and the equity in the property. Rent is not the qualifier.
Availability is also narrower than the DSCR side. NerdWallet’s overview of HELOCs on investment property notes that these lines are limited in availability and carry strict requirements. Lendmire brokers the investment-property line through select wholesale partners in 16 full-service states, which is narrower than its 41-market DSCR footprint, Washington, D.C. included.
Key Terms Defined
HELOC: A revolving credit line secured by property. You draw funds as needed and repay over time.
CLTV (combined loan-to-value): All loans against the property, added together, divided by its value. The first mortgage and the line both count.
Draw period: The stretch when you can borrow from the line and pay interest only.
Repayment period: The stretch after the draw period when you can no longer borrow and the balance amortizes, meaning principal is paid down.
Vesting: The legal name that holds title: you, a trust, or an entity.
DTI: Your monthly debt payments divided by your monthly gross income.
PITIA: Principal, interest, taxes, insurance, and association dues. This is the payment a DSCR loan compares to rent.
How the Line Gets Sized, Step by Step
Sizing follows one formula: value times the CLTV ceiling, minus every existing lien. Then the program caps trim the result. Here is the sequence a lender walks through.
1. Classify the occupancy. The property is primary, second home, or investment. That label sets the ceiling.
2. Establish value. On an investment line of $500,000 or less, valuation is ordinarily automated with no traditional appraisal. A full appraisal is required above $500,000, and you can request one anyway.
3. Apply the ceiling. On an investment property, the network ceiling is 70% CLTV.
4. Subtract existing liens. Your first mortgage stays in place, but its balance eats into the room.
5. Test the full limit. Leverage is measured on the whole credit line, drawn or not.
6. Test the borrower. Credit, DTI, and income documentation comes next.
7. Apply caps and title rules. The line runs $25,000 to $500,000 on an investment property, and title must be eligible.
Run the percentages. With a 70% ceiling and a first mortgage at 50% of value, you have 20 points of room. With the first mortgage at 60%, you have 10 points. A paid-off rental offers up to 70 points before the dollar cap applies. These are modeled illustrations, not quotes.
One market comparison belongs here. Market surveys report investment-property HELOC maximums of 80% loan-to-value, with many lenders sitting below 70%, per NerdWallet. That describes the broader market. On Lendmire’s network, an investment line tops out at 70% CLTV, and nothing sits above it.
Which Limit Binds First?
| Situation | Binding limit | What it means |
|---|---|---|
| Heavily mortgaged rental | Equity room | First mortgage eats the 70% |
| Low-balance, high-value rental | $500,000 cap | Dollar cap hits before equity |
| Strong equity, heavy business debt | DTI | 50% maximum, tested at full draw |
| Credit under 700 | Eligibility | No investment line at all |
Credit above 700 buys eligibility, not leverage. A 720 score and a 700 score reach the same 70% ceiling on an investment property. Compare that to a primary residence, where the ceiling reaches 90% CLTV, but only at a 720-or-better credit profile. Lines above $500,000 are for primary residences only, capped at 75% CLTV with a full appraisal. Never let a primary-home figure describe a rental.

How Self-Employed Income Gets Documented
Business owners are underwritten on documented income under the applicable program, subject to lender guidelines. Two paths exist.
Bank statements. The lender reviews 12 to 24 months of consecutive statements. Transfers, loan proceeds, and refunds come out of the deposits. On business accounts the lender then applies an expense factor. The lender sets that factor, not you. Business accounts need a 680 minimum credit profile for the deposit analysis. Since an investment line already floors at 700, that rule never becomes the binding one here.
Full documentation. Two years of personal and business returns, often with a year-to-date profit-and-loss statement. Separate asset statements prove reserves.
Heavy write-offs are the catch. Deductions that lower your taxable income also lower return-based income, even when deposits look strong. That is the main reason business owners lean toward the bank-statement path. It is still full underwriting. Different paper trail, not no paper trail.
What the Line Costs to Carry
Investment lines on this network run one structure: a 5-year interest-only draw period, then a 25-year fully amortizing repayment period. The payment floats across both periods and never converts to a fixed amount. At least 75% of the line is drawn at closing.
Two consequences follow.
First, the standing reserve is not free. If three-quarters of the line is drawn on day one, you are carrying that balance whether the business needs it or not. And the full limit counts toward CLTV regardless. Drawing less later does not lower the leverage the lender tested.
Second, DTI is qualified on the interest-only payment calculated on the maximum draw. The lender assumes you borrow everything. If you plan to draw half, you still qualify as though you draw all of it.
Then comes the payment step-up when interest-only ends and amortization begins. Business owners with lumpy income should stress-test that moment. Ask whether the business can carry a larger payment in a slow quarter, and with a payment that floats, not just a flat one. After the closing draw, the minimum subsequent draw is typically $1,000, with Texas at $4,000.
Sizing the Line to the Purpose
Can borrow and should borrow are different numbers. Lendmire’s piece Investment Property HELOC for Owners Sizing How Much Equity to Borrow covers that decision in more depth. A working rule: match the line to a defined use, then size to that use with a cushion.
| Use of funds | Sizing logic |
|---|---|
| Business build-out | Size to the quoted project cost plus a cushion |
| Down payment on next rental | Size to the percentage down plus reserves |
| Working-capital bridge | Smaller line, repaid from receivables |
| Open-ended opportunity fund | Hard to justify; the closing draw makes it costly |
That last row deserves a skeptical look. Because most of an investment line is drawn at closing, a “just in case” line is rarely just in case. If your need is large and one-time, a cash-out refinance may fit better. If it is small and recurring, the line fits.
On down payments, a HELOC can fund part of the next purchase. Purchase leverage on DSCR files commonly lands at 75% to 80% LTV, so you still need real cash and reserves behind the deal. Reserves commonly run around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type.
Where the General Rule Breaks
Most of what you just read assumes an individual owner, a standard rental, and a clean file. These are the cases where it bends.
LLC title is the big one. This product requires title in your individual name or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. Investors report the same wall elsewhere. A CPA in one BiggerPockets discussion of HELOCs on LLC-held properties says most banks will not lend a line directly to an LLC, though a few will write second-position lines on LLC-titled property.
You have a few routes if your rental sits in an LLC:
- Re-vest title to yourself or a revocable trust. Re-titling a mortgaged property typically needs the servicer’s consent.
- Draw on a different property you own personally, then contribute the funds to the LLC. The risk: your personal asset now secures money working inside the rental business.
- Use a DSCR cash-out instead. DSCR loans to LLC-titled borrowers are available subject to lender program eligibility.
The house-hack duplex. Live in one unit and the lender may review the line as a primary residence, with a different ceiling. Rent both units and it is an investment line. Say which one it is before you apply, because the occupancy label drives everything.
Business-purpose treatment. Credit used to acquire, improve, or maintain a non-owner-occupied rental is generally treated as business purpose under Regulation Z’s business-purpose exemption, and the same text includes a 14-day owner-occupancy test. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. Banks that decline rental lines are making product and credit-policy choices. Nothing in federal law bans them.
Recent purchases. Seasoning is lender policy. Some lenders cap the value they will use at your purchase price until their waiting period runs. If you bought recently, ask before you assume your appraisal-level value counts.
Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
Texas. The 12-day waiting period and one-lien-at-a-time rule bind primary residences only. Investment properties are eligible as non-homestead, and Texas properties are limited to 10 acres.
Property types. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Portfolio limits. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible. Landlords with big portfolios often hit this limit before anything else.
HELOC or DSCR Cash-Out?
Think of it as two different tests. A HELOC leaves your first mortgage untouched and tests you. A DSCR cash-out replaces the first loan and tests the property.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| Reviewed on | Borrower credit, DTI, equity | Rent covering the payment |
| First mortgage | Stays in place | Replaced |
| Title | Individual or revocable trust | LLC possible, per program terms |
| Leverage | 70% CLTV on investment property | Around 75% on standard rentals; 70% on short-term rentals |
| Size | $25,000 to $500,000 | Up to $3,000,000 on standard programs |
A HELOC fits when your existing first mortgage is worth keeping and your cash need is modest. A DSCR cash-out fits LLC-held property, a larger need, or personal income that tax deductions have thinned. Cash-out files typically expect about 6 months of seasoning.
Coverage thresholds deserve care. Many select DSCR programs start at 1.00 coverage, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. And clearing 1.00 is not the same as positive cash flow: repairs, vacancy, management, utilities, and capex sit outside the calculation. For the full picture, see the complete DSCR loans guide.
One practitioner pattern shows up often. Business owners with strong deposits and a low first mortgage do well with the HELOC. Business owners with an LLC-held rental, or an expensive first mortgage they would rather not touch, usually end up on the DSCR side. Running both is how you find out which.
What You Are Really Risking
The line is secured by the property, so failure to repay can mean losing it. The CFPB’s HELOC booklet says as much, and also warns that renting out a home may be prohibited under a line’s terms. Read yours.
Three risks specific to business owners:
- Concentration. Rental, line, and business income may all weaken in the same downturn.
- Collateral crossover. A line on a primary home that funds a rental business puts the home at risk.
- A lender can restrict a line. Value drops or credit changes can limit access to money your plan depended on.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Readiness Checklist
- Confirm title is in your name or a revocable trust.
- Know your first mortgage balance and the property’s likely value.
- Pull your credit and confirm it sits at 700 or better.
- Gather 12 to 24 months of business bank statements, or two years of returns.
- Add up every monthly debt payment for the DTI test, assuming a full draw.
- Write down the purpose and the amount you need.
- Check your count of lines and financed properties.
Frequently Asked Questions
Can I get a HELOC on a rental if my income is mostly from my business?
Yes, if the file documents. Business owners usually qualify on documented income under the applicable program, via 12 to 24 months of bank statements or full traditional personal-income documentation. The lender still tests credit, DTI, and equity. Investment lines need a 700 minimum credit profile on this network.
How much can I borrow against one rental?
Up to 70% CLTV on an investment property, minus your existing liens, capped at $500,000 and subject to lender guidelines. The minimum line is $25,000. There is no tier above $500,000 for investment property.
Do I need an appraisal?
Usually not. Lines of $500,000 or less ordinarily use automated valuation, though a higher CLTV may require a secondary valuation. You can request a full appraisal in any case.
Can my LLC hold the property?
Not for this product. Title must sit with you or a revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead.
Does drawing less lower my combined leverage?
No. Leverage is tested on the full credit limit, drawn or not. At least 75% of an investment line is drawn at closing anyway.
