The Quick Read: On most files, you need a 700 or better credit profile, 70% or lower combined loan-to-value on the property, a debt-to-income ratio at or below 50%, and title held in your own name or a revocable living trust rather than an LLC, with the line capped at $500,000 on an investment property, subject to lender guidelines. This is a line of credit underwritten on you, not on the rent. The rental’s income helps only as a supporting document. If the property sits in an LLC, or your personal debt-to-income is already stretched, a DSCR cash-out refinance is usually the better fit.
- Investment lines top out at 70% combined loan-to-value (CLTV), and 700 is the credit floor.
- Both 720 and 700 reach the same 70%, so a higher score buys eligibility rather than leverage.
- The line runs from $25,000 to $500,000 on an investment property.
- The structure is a 5-year interest-only draw followed by a 25-year repayment, with pricing that floats throughout.
- Brokered availability is limited to 16 states, so confirm the property’s state before anything else.
What Is an Investment Property HELOC?
An investment property HELOC is a revolving line of credit secured by a rental you own. You draw against the line when you need cash and pay interest only on what you have drawn. The CFPB describes a HELOC as an open-end line with a draw period, and notes that a lender may restrict further draws if the property’s value falls significantly.
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.
Lendmire is a mortgage broker. It arranges these lines through select wholesale partners and is never the lender. The line can sit in first or second lien position, so it works whether or not the rental already carries a mortgage.
The product is different from a DSCR loan, and mixing the two causes most of the confusion. A HELOC asks whether you can carry the debt. A DSCR loan asks whether the property can. That one difference decides most of what follows.
How Do Lenders Underwrite an Investment HELOC, Step by Step?
Underwriting runs in a fixed order: equity first, then credit, then income and debts, then the property and title. Each step is a gate, and a file that fails any one of them stops there. Here is the sequence across the wholesale programs we place files with.
Step 1: Equity and combined leverage
The lender adds your existing mortgage balance to the new line and divides by the property’s value. That is the CLTV. On an investment property the ceiling is 70% CLTV, with no tier above it. Primary-residence lines are different: they reach 90% CLTV, but only at a 720 or better credit profile. That higher ceiling never applies to a rental.
The wider market is more generous on paper. NerdWallet reports that market lenders often cite loan-to-value up to 80%, though many sit lower. For Lendmire’s network, the investment figure is 70% CLTV, with no exceptions.
Step 2: Credit
The network’s program floor across all occupancies is 600, but investment lines require 700. There is no tier beneath that. The score model is a single-bureau pull keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not available.
Investment lines sit well above owner-occupied credit expectations.
Step 3: Debt-to-income
Maximum debt-to-income is 50%. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to draw. Your existing debts count too: the primary mortgage, other rentals, cards, and auto loans.
This is where portfolio investors run into trouble. Each financed rental adds debt, and the lender may count only part of its rent as income.
Step 4: Rental income documentation
Expect to provide leases, and in some cases tax returns that show the rental’s results. Lender treatment of rental income varies, so describe your documentation honestly and early. The key point is that rent supports the file but does not carry it.
A rental that shows a tax loss on the return can drag qualifying income down. Depreciation and expenses reduce reported net rental income even when the property cash-flows in real life. Self-employed borrowers should expect that conversation up front.
Step 5: Valuation
Because an investment line caps at $500,000, and full appraisals are required only above that amount, these files run in the automated-valuation lane. Many close with no traditional appraisal. A higher CLTV may trigger a secondary valuation, and a borrower can request a full appraisal in any case.
Step 6: Title and vesting
Title must be fee simple or leasehold, held by you as an individual or by your inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest structural difference from a DSCR loan, and it is the first thing to check if you own through an entity.
What Does the Line Structure Look Like?
Investment lines run one structure: a 5-year interest-only draw, then a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats across both the draw and repayment periods and never converts to a fixed figure.
The minimum line is $25,000. A borrower is limited to three lines, and a borrower who owns more than 15 financed properties is not eligible. Combined-exposure caps also apply across lines, and they differ by wholesale program.
That 75% draw at closing matters for planning. Many investors picture a line as dormant cash they pull from later. Here most of the line is drawn up front, so the carrying cost starts immediately. The CFPB’s home equity guide also notes that lenders typically want you to keep 10% to 20% of value as equity in the owner-occupied context. The investment cushion is larger, since the network ceiling leaves 30% of value untouched.
What Properties and Borrowers Are Eligible?
Eligible property types are single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos. Not eligible: manufactured homes, co-ops, condotels, log homes, commercial property, mixed-use property, and agricultural zoning.
On derogatory credit, a bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year seasoning path for a foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale. Housing history requirements vary by wholesale program and apply across all financed properties.
How Much Line Can You Actually Get? A Worked Example
Run the numbers in percentages. Say a rental is worth 100% of its appraised value and carries a first mortgage equal to 50% of that value. The 70% CLTV ceiling leaves room for a line of up to 20% of value, assuming credit and debt-to-income clear.
Now change one input. If the first mortgage is 60% of value, the room shrinks to 10% of value. On a modest-value rental, that may fall below the $25,000 minimum line, and then the product simply does not fit.
The cap works from the other direction too. On a high-value property with little debt, 70% CLTV could allow more than the line limit. The $500,000 maximum then binds first. Whichever of the three limits is smallest decides the line: the CLTV room, the $500,000 cap, or what your debt-to-income allows on the maximum-draw payment.
Debt-to-income can quietly be the binding limit. Because the lender tests the payment on the full line, a borrower with several financed properties may qualify on equity and still fail on the ratio.
How Does a Primary-Home Line Compare?
Investors often ask whether to borrow against their own home instead of the rental. The ceilings differ sharply.
| Factor | Investment property line | Primary residence line |
|---|---|---|
| Max CLTV | 70% | Up to 90% at 720+ only |
| Minimum credit | 700 | Lower floors apply |
| Max line size | $500,000 | $750,000 |
| Draw structure | 5-year draw, 25-year repay | Two structures available |
Lines above $500,000 are primary-residence only. They need 700 or better credit, or 720 on the longer-runway structure, cap at 75% CLTV, and require a full appraisal. The White Coat Investor notes that fewer lenders offer lines on rentals at all, which is why a primary-home line is a common alternative.
Using a primary-home line to fund a rental purchase raises its own questions. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Where Does the General Rule Break?
Four edge cases trip up borrowers more than anything else.
The LLC-held rental. The title rules above are strict. A property already deeded to an LLC needs a vesting change, or it needs a different product. Moving title can have its own consequences with insurance and existing financing, so check those before you sign anything.
The heavily financed portfolio. Past 15 financed properties the line is off the table. Well before that, debt-to-income usually bites. In that case rent-based underwriting is the cleaner route.
The self-employed borrower with a tax loss. The return tells the lender one story and the rent roll tells another. Expect the return to win.
The condo or small multifamily. These are eligible, including non-warrantable condos, but the same 70% ceiling applies. Nothing about the property type raises leverage.
When Does a DSCR Cash-Out Refinance Fit Better?
A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Personal debt-to-income is not the gate. Across the wholesale network, this is the practical answer when the HELOC conditions fail. Lendmire’s complete DSCR loans guide covers the full mechanics.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Underwritten on | Your income and DTI | Rent against the payment |
| Max leverage | 70% CLTV | About 75% LTV, standard rentals |
| Short-term rentals | Same 70% cap | 70% LTV for STR collateral |
| LLC title | Not allowed | Allowed, per program terms |
| Structure | Floating line | 30-year fixed spine, with extended terms and interest-only available through select lenders |
| Loan size | $25,000 to $500,000 | Up to $3,000,000 on standard programs |
On the DSCR side, 1.00 is where many select programs start, and stronger ratios can open better leverage and pricing. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Credit minimums run from a 620 floor in parts of the network to about 660 on most programs, with 700 or better unlocking the strongest tiers. Cash-out files commonly expect about 6 months of seasoning, and reserves of around 6 months of the full monthly obligation are common, though that varies by lender, leverage, and loan size.
One caution on the ratio. Clearing 1.00 does not mean the property produces positive cash flow, because repairs, vacancy, management, and capital expenses sit outside the calculation.
The trade-off is structural. A cash-out refinance replaces the whole first mortgage, so you give up any existing loan you value. A HELOC leaves the first mortgage untouched. The cash-out also raises the balance, which lowers coverage. Run both before choosing; the flip point is usually title and personal debt load.
Which Route Fits Which Investor?
- Individual owner with strong credit, moderate debts, and low existing leverage: the HELOC is worth pricing. It leaves the first mortgage alone.
- LLC-held rental, or a larger portfolio: DSCR cash-out is usually the only workable path.
- Self-employed borrower whose returns show rental losses: DSCR often reads the property more cleanly than the tax return does.
- Borrower with 700+ credit who wants maximum leverage: a primary-home line can reach higher CLTV at 720 or better, and a DSCR cash-out may beat the 70% investment cap.
Key Terms Defined
CLTV: Combined loan-to-value is all loans against the property, including the new line, divided by its value.
Draw period: The stretch during which you can borrow from the line, which is 5 years on an investment line.
Debt-to-income (DTI): Your total monthly debts divided by your monthly income, with a 50% maximum on these lines.
Vesting: The way title to the property is held, such as an individual or a revocable living trust.
DSCR: Debt service coverage ratio, which compares a rental’s monthly rent to its full monthly obligation.
How to Prepare Before You Apply
1. Confirm title. If the property is in an LLC, decide whether a vesting change or a DSCR loan makes more sense.
2. Pull your credit. Check that your score clears 700 before the lender pulls a report that will count for 90 days.
3. Total your debts. Add every financed property, then test your ratio against 50%.
4. Estimate equity. Subtract your current balance from 70% of value. That is the maximum room.
5. Gather leases and returns. Have the rent roll and recent returns ready.
6. Check availability. Brokered equity lines are available in 16 full-service states, narrower than the 41-market DSCR footprint, so check yours first.
Frequently Asked Questions
Can I use an LLC-owned rental for a HELOC?
No. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. Title must be an individual or an inter vivos revocable living trust. An LLC-held rental either needs a vesting change or a DSCR cash-out refinance, which can work with entity ownership per program terms.
What credit score do I need for an investment line?
700 is the hard floor, and there is no tier beneath it. A 720 score reaches the same 70% CLTV as 700, so a higher score does not raise leverage. Market surveys report higher typical expectations, often 720 or above, but the network figure is 700.
Do 2-4 unit properties qualify?
Yes. Single-family homes, 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.
Will a traditional appraisal be required?
Usually not. An investment line caps at $500,000, and full appraisals are required only above that amount, so these files commonly run on an automated valuation. A higher CLTV may call for a secondary valuation, and you can always request a full appraisal.
What if I am declined?
Check which gate failed. A title problem points to a vesting change or a DSCR loan. A debt-to-income problem points to the same, since rent-based underwriting does not run on your personal ratio. A credit shortfall may be fixable over time, and a bankruptcy needs 4 years of seasoning.
