The Quick Read: On an investment-property home equity line, the line size comes from value, not rent: the appraised or automated value is multiplied by the 70% combined-loan-to-value ceiling, the existing liens are subtracted, and the result is cut down by a $500,000 dollar cap and your debt-to-income limit. Across Lendmire’s wholesale network, most investment lines are valued by software, not a traditional appraisal. Every figure here is subject to lender guidelines and full file review.
- Equity sets the line. A rental with strong rent but thin equity gets a small line or none.
- On an investment property, the ceiling is 70% combined loan-to-value (CLTV), and the maximum line is $500,000.
- Credit of 700 or better is the floor, and a higher score buys eligibility, not more leverage.
- The title must sit with you personally or in your revocable living trust. An LLC cannot hold it.
- Lines at or below $500,000 ordinarily use an automated valuation, though you may request a full appraisal.
Key Terms Defined
HELOC: A home equity line of credit is a revolving loan secured by property. You draw, repay, and draw again within the limit.
CLTV: Combined loan-to-value adds every loan secured by the property, including the new line, and divides the total by the property’s value.
AVM: An automated valuation model is software that estimates value from public records and recent sales, with no one visiting the property.
Lien position: This is your lender’s place in line if the property is sold or foreclosed. The first mortgage sits in first position, and a line behind it sits in second.
Draw period: The draw period is the stretch when you can borrow from the line, usually paying interest only.
DTI: Debt-to-income compares your monthly debts to your monthly income. Investment lines read you, the borrower, through this number.
Vesting: Vesting is how title is held, whether in your own name, a trust, or an entity.
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.
How Landlords Sizing the Line From Appraisal Get to a Number
Here is the sequence a lender follows. The order matters because each step can shrink the result, and the smallest answer wins.
1. Establish value. The lender gets a valuation of the rental. On a line this size, that is usually an automated estimate.
2. Apply the CLTV ceiling. On an investment property, the network ceiling is 70% CLTV. Multiply value by 0.70 to get the most total debt the property can carry.
3. Subtract existing liens. Take out the first mortgage balance and any other loans secured by the property. What remains is the equity room.
4. Count the full limit. Lenders generally measure CLTV on the whole credit limit, not on what you have drawn so far. Drawing less does not make the test easier.
5. Apply the dollar caps. The line cannot pass $500,000 on an investment property, and the minimum line is $25,000 (Michigan lowers the floor to $10,000). If your equity room falls below the minimum, there is no line to offer.
6. Underwrite the borrower. Credit and DTI come next. The maximum DTI is 50%, tested on the interest-only payment calculated on the maximum draw.
The line is the smallest of what the equity allows, what the dollar cap allows, and what your DTI supports. Rent does not size it. That is the sharpest difference from a DSCR loan, which weighs rent against the full monthly obligation.
A modeled sizing example
These inputs are modeled assumptions, not market data. Say the first mortgage equals 50% of the property’s value, and the 70% ceiling applies.
- Total debt allowed: 70% of value.
- Less the first mortgage: 50% of value.
- Equity room for the line: 20% of value.
Whether that room is large or small in dollars depends on the property. On a modest rental, 20% of value may land near the $25,000 minimum or below it. On a high-value property, 20% of value may exceed $500,000, and then the dollar cap decides.
Does a Rental HELOC Need an Appraisal?
Usually not. An investment line cannot exceed $500,000, and full appraisals are required only on lines above $500,000, which are limited to primary residences. An investment line is therefore structurally in the automated-valuation lane and commonly closes with no traditional appraisal.
Three exceptions are worth knowing. A higher CLTV may call for a secondary valuation. You may ask for a full appraisal in any case. And a property with unusual features, such as an odd layout or thin sales nearby, is a good candidate for asking.
| Valuation type | When it applies | Who it suits |
|---|---|---|
| Automated (AVM) | Ordinary lines up to $500,000 | Typical rentals with plentiful local sales |
| Secondary valuation | May be added at higher CLTV | Files close to the 70% ceiling |
| Full appraisal | Required above $500,000; you may request one | Unusual or recently renovated properties |
The borrower typically carries the cost of the valuation. Lender-side costs and fees vary by file, so ask for the fee schedule before you commit.
What Happens if the Value Comes In Low?
The line shrinks faster than the value does. The reason is that liens do not move. Using the same modeled example (first mortgage at 50% of today’s value, ceiling at 70%), here is how a swing in value changes the equity room:
| Value swing | Total debt allowed (% of today’s value) | Room for the line (% of today’s value) |
|---|---|---|
| Down 10% | 63% | 13% |
| Down 5% | 66.5% | 16.5% |
| As expected | 70% | 20% |
| Up 5% | 73.5% | 23.5% |
| Up 10% | 77% | 27% |
A 10% miss on value cuts the room by 35%. Rental owners who plan to draw close to the limit should treat a software estimate as a range and test the low end.
If the estimate seems off, you have options. Check that the property record, unit count, and square footage in public data are correct. Ask whether the lender will accept a full appraisal in place of the model. A completed renovation may support a higher appraised value, depending on comps and underwriter review. Software often misses recent work, so a human appraisal is the natural fix.
Gates That Shrink the Line Before the Math Starts
Some borrowers never reach the sizing steps. These gates decide first.
- Credit. The minimum on an investment property is 700. Both 720 and 700 reach the same 70% CLTV, so a higher score adds no leverage here. The score comes from a single-bureau model keyed to the primary wage earner. The report must be no more than 90 days old at closing, and rescores are not available.
- Title and vesting. The property must be 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. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out may fit better.
- Property type. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not offered.
- Credit history. 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.
- Exposure. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage wholesale program and $750,000 on the longer-runway wholesale program. A borrower with more than 15 financed properties is not eligible.
- Listing status and location. A property listed for sale, or listed within the past 60 days, is ineligible in several states. Lendmire arranges these lines in 16 full-service states, a narrower footprint than its 41-market DSCR coverage, so confirm your state first.
Another gate catches investors off guard. Some large retail lenders write only owner-occupied lines, so a rental may be declined before any sizing. NerdWallet’s investment-property HELOC explainer gives the reasoning: lenders see default risk as higher on a rental, because borrowers are more likely to pay the bills on their own home first.
Home-Secured Line or Rental-Secured Line?
The same word covers two different products. A line on your own home and a line on the rental behave differently, and the occupancy of the collateral changes the ceiling.
| Factor | Line on your primary home | Line on the rental |
|---|---|---|
| Collateral at risk | Your residence | The rental property |
| CLTV ceiling | Up to 90% at 720 or better | 70% |
| Maximum line | Up to $750,000 | $500,000 |
| Valuation | Full appraisal above $500,000 | Automated lane |
| Title | Individual or revocable trust | Individual or revocable trust |
Primary-home and second-home lines reach 90% CLTV only at a 720-or-better credit profile. Primary-residence lines above $500,000 also need a full appraisal and cap at 75% CLTV. Those higher figures belong to lines on the home, never to a rental.
Borrowing against your home to fund a rental carries a cost that the table hides. The CFPB’s HELOC booklet defines a HELOC as a loan that lets you borrow, spend, and repay as you go, using your home as collateral. It also warns that renting your home out to others may be prohibited by the terms of your line. That is a reason to stay clear of the “open it as a primary and convert later” idea sometimes floated among investors. Misstating how you will occupy the property is a risk, not a workaround.
How the Line Works After You Size It
A line is a structure, not just a number. On an investment property, the network runs one structure only: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats through both the draw and the repayment period and never converts to fixed. Payments can therefore move over time.
At least 75% of the line is drawn at closing. That matters for sizing, because you are not choosing a small limit and drawing nothing. Afterward, a later draw carries a $1,000 minimum on the longer-runway program.
The line can sit in first or second lien position, which gives you room to keep a low first mortgage in place. That is often the case for a HELOC over a cash-out refinance: the first mortgage stays untouched.
For contrast, NerdWallet describes a typical market structure as a 10-year draw followed by a repayment period of up to 20 years. That is a market-wide description. The network’s investment line is the 5-year draw and 25-year repayment above.
HELOC, DSCR Cash-Out, or Something Else?
A HELOC reads you and adds a second lien. A DSCR cash-out refinance reads the property and replaces the first mortgage.
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. DSCR qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The ratio compares rent to the full monthly obligation: principal, interest, taxes, insurance, and association dues.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Sizing basis | Value, CLTV, credit, DTI | Value, LTV, and rent coverage |
| Leverage | 70% CLTV on an investment property | Around 75% LTV on a standard rental |
| Entity title | Not allowed | May be allowed, subject to program terms |
| Existing first mortgage | Stays in place | Replaced |
| Credit | 700 minimum | Commonly around 660; 620 in parts of the network |
On a cash-out refinance of a standard rental, most programs in the network top out around 75% LTV, and about 6 months of seasoning is the common expectation. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and a rental held in an LLC can often be financed, subject to lender program eligibility.
Coverage is a separate question. Select programs start at 1.00, and stronger ratios open better terms. A separate path through select lenders in the network takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 does not mean positive cash flow, since repairs, vacancy, management, utilities, and capital spending sit outside the ratio.
For the full picture, see Lendmire’s complete DSCR loans guide.
In files like these, the deciding factor is often the first mortgage. A borrower with a low-cost first mortgage and modest equity needs usually leans toward a second-lien line. A borrower who wants to restructure the whole debt, or who holds title in an LLC, usually moves toward DSCR cash-out.
Mistakes Landlords Make When Sizing
- Measuring on the drawn amount. Lenders generally count the full limit, so a small first draw does not lower CLTV.
- Using the wrong value. Your purchase price, an old appraisal, and a model estimate are three different numbers. The lender uses its own.
- Forgetting other liens. A second loan, a tax lien, or a prior line all come off the room.
- Borrowing the primary-home ceiling in your head. The 90% figure belongs to owner-occupied lines at 720 or better. A rental caps at 70%.
- Assuming rent counts. A strong lease does not enlarge the line.
- Ignoring title. An LLC-owned rental fails before sizing begins.
- Skipping the tax question. 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.
What the Decision Looks Like in Practice
Picture a landlord with a rental held personally and a modest first mortgage. She wants down-payment money for the next purchase. She checks her score first, because 700 is the floor. Then she runs the equity room at the 70% ceiling, tests it against a 5% lower value, and compares the result with the minimum line size.
If the room clears the minimum, she can apply for the line. If it falls short, she looks at a larger cash-out through DSCR instead, or waits for more equity.
She also thinks about the purchase it funds. A DSCR lender will review how borrowed funds count toward cash to close. A fresh line also shows up on her credit report and in DTI, which can limit how many more she can add.
Frequently Asked Questions
Can I get a HELOC on a rental if the property sits in an LLC?
Not on this program. Title must be held by you individually or by your revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance may fit better, subject to lender program eligibility.
Does drawing less than the limit improve my CLTV?
Generally no. Lenders count the full credit limit in the CLTV test. The DTI test also runs on the interest-only payment at the maximum draw, so a smaller first draw does not ease either one. At least 75% of the line is drawn at closing on these programs.
What if I disagree with the automated value?
Ask for a full appraisal. You may request one in any case, and it makes the most sense after a renovation or on an unusual property. Whether it changes the line depends on comps and underwriter review.
Will a higher credit score give me more room?
Not on an investment property. A 720 and a 700 both reach the same 70% CLTV, so a higher score adds eligibility, not leverage. The 90% CLTV figure belongs to owner-occupied lines at 720 or better.
Is a HELOC better than a cash-out refinance?
It depends on the first mortgage and the title. A HELOC keeps the first mortgage in place and adds a second lien. A cash-out refinance replaces the first mortgage and may allow entity title. Compare your equity, credit, and goals on both.
