The Quick Read: No national ranking of these providers exists, and the lenders that write a line against a rental depend on your credit, your equity, how the property is titled, and where it sits. A rental line goes in second position behind your current mortgage, so the first loan keeps its balance, term, and payment. Lendmire is a mortgage broker, not a lender. It matches your file to the wholesale HELOC lenders whose guidelines fit it.
- On an investment property, the network ceiling is 70% combined loan-to-value, with a 700 minimum credit score.
- The investment line tops out at $500,000 and runs a 5-year draw followed by a 25-year repayment.
- The property must be titled to you personally or to a revocable living trust. An LLC cannot hold title.
- A traditional appraisal is often not required at this size, since automated valuation is the usual route.
- If the title, credit, or equity does not fit, a rent-based cash-out refinance is the usual fallback, and it replaces the first lien.
How a Rental HELOC Leaves the First Lien Alone
A rental HELOC sits behind your existing mortgage as a second lien. The first loan is never touched. The new line draws only on the equity left over after that first balance.
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.
Think of two claims stacked on one property. The first lender is paid first if the property is ever sold or foreclosed. The second lender is paid from whatever remains. Because the second lender takes more risk, it wants more cushion in the property, and that is why rental lines are tighter than the ones banks write on a primary home.
This matters most if you hold an older first loan with terms you would never get again. A cash-out refinance would replace that loan. A second-position line reprices only the money you actually borrow. The first mortgage stays exactly as it is.
A rental with no mortgage can take a first-position line instead. That is a different file, because the line is then the only lien on the property.
Who Provides These Lines (and Why the List Is Short)
Few providers write lines against rentals, and any ranked list of them goes stale. NerdWallet says a HELOC on an investment property is possible. It adds that you may have a smaller pool of lenders and can’t borrow as much as against a primary home. It also notes that not all lenders offer one and that requirements are strict.
Here is how the supply breaks down by type of provider:
- Local banks and credit unions. Some will lend against a rental, usually only inside their own footprint and often only to individuals with a long relationship. Many will not touch a rental at all.
- Large retail lenders. Their rental-property appetite changes often, and product availability depends on the property type and location.
- Wholesale HELOC lenders reached through a broker. These lenders do not sell to the public. A broker brings the file to them and matches it to the guidelines that fit.
- Rent-based lenders. These do not write equity lines. They write DSCR cash-out refinances, which are covered below.
The best provider for you depends on your situation: the property type, your credit profile, how much leverage you need, and how the property is titled. Naming a winner without those facts would be guesswork.
Lendmire works with a network of wholesale HELOC lenders and places the file with the one whose guidelines fit. Across the wholesale programs it places files with, the rules are tight on title, credit, and combined leverage. Those are the three things to check first.
Step by Step: How Underwriting Treats a Rental Line
An equity line on a rental is reviewed on you first and the property second. The lender looks at your credit, your debts, and your equity. It does not primarily look at what the property rents for.
Here is the sequence a file follows.
1. Pick the collateral. The line can be secured by the rental itself. Some lenders will instead take your primary home, which can help when no lender will write against the rental.
2. Choose the lien position. A mortgaged rental takes a second-position line. A paid-off rental can take a first-position line. Choosing second position on purpose is what keeps your current first loan in place.
3. Run the combined loan-to-value, or CLTV. Add your first balance and the new line, then divide by the property’s value. The lender’s ceiling caps that number.
4. Check credit and debts. Lenders pull a credit report, review your housing history, and look at your total debt load. On the investment line in the network, the maximum debt-to-income ratio is 50%, and a score of 700 is a hard floor.
5. Value the property. Most lines at this size use an automated valuation model, which estimates value from data instead of an on-site visit.
6. Verify title and documents. Expect a current first-mortgage statement, an insurance declaration, a vesting deed, and income documents.
7. Fund and draw. At least 75% of the line is drawn at closing on the programs in the network. After that, you draw as needed.
One quirk in step 4 deserves attention. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. A line sized larger than you need still counts against your debt ratio in full.
What the Investment Line Looks Like on the Network
The investment-property line in this network is narrower than a primary-home line, and the figures differ by occupancy. Everything below is a typical guideline, subject to lender review and full file review. None of it is a commitment to lend.
- Leverage. On an investment property, the ceiling is 70% CLTV. That holds at both the 700 and the 720 credit tiers, so a higher score on an investment line buys eligibility but not extra leverage. NerdWallet’s market summary says lenders commonly want at least 20% equity left in the property, which implies a ceiling near 80% CLTV. The network figure for an investment line is 70%.
- Line size. The investment line runs up to $500,000. Only primary residences can carry a line above that amount.
- Structure. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. NerdWallet describes bank structures with a 10-year draw. The investment line in this network uses the 5-year draw.
- Pricing behavior. Pricing floats through both the draw and the repayment period. It never converts to a fixed figure.
- Wholesale programs. Lendmire places these files with two wholesale programs. One is built for higher leverage. The other offers a longer interest-only runway on primary and second homes. The investment limits above are the ones that matter for a rental.
- Credit. The report can be no more than 90 days old at closing. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files season a foreclosure at 7 years, and a deed-in-lieu, pre-foreclosure, or short sale at 4 years.
- Exposure. A borrower can hold up to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway one. A borrower who owns more than 15 financed properties is not eligible.
- Where it is offered. The HELOC product is available only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the DSCR footprint, which spans 41 markets including Washington, D.C.
Because the investment line caps at $500,000, and full appraisals are required only on lines above that amount, a rental line sits structurally in the automated-valuation lane. A higher CLTV can still trigger a secondary valuation, and you can always ask for a full appraisal.
Sizing the Line: The CLTV Math in Percentages
The maximum line is the CLTV ceiling times the value, minus every lien already on the property. The CFPB’s HELOC booklet illustrates the same idea: take a percentage of the home’s value, then subtract the mortgage balance.
Run it in percentages. Say your first mortgage equals 45% of the property’s value. At the 70% investment ceiling, you have room for a line worth up to 25% of value. Any second mortgage, tax lien, or other lien shrinks that room dollar for dollar.
Now take a heavier case. Say your first loan equals 65% of value. Only 5% of value is left under the ceiling. That sliver often cannot support the $25,000 minimum line, so the file stalls, however strong your credit is.
This is why investors who bought with high leverage often find rental lines unavailable. The first loan has eaten the room. It is also why a recent purchase with a small down payment is a poor candidate.
Stacked leverage carries a second cost. A line plus the first lien consumes the equity a later cash-out refinance would use. Run the combined math before you borrow twice against the same property.
Where the General Rule Breaks
Rental-line stalls tend to come from a handful of edge cases: entity title, property type, listed property, state quirks, and primary-home collateral. Each one is worth checking before you apply.
Entity title. On the network’s investment line, only an individual or an inter vivos revocable living trust can hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. A property already deeded to an LLC needs a vesting change first, or it needs a different product. DSCR cash-out loans can often be written to LLC-titled properties, subject to lender program eligibility.
Property type. Eligible properties are single-family homes, 2-4 unit buildings, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Listed or recently listed. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
State quirks. Texas investment properties qualify as non-homestead transactions and are limited to 10 acres. New Mexico and Ohio set a CLTV cap that depends on the credit profile. Michigan’s minimum line is $10,000, and Texas sets a $4,000 minimum for later draws.
Primary-home collateral. If the line is secured by your primary home, the loan agreement may prohibit renting that home out. Read the agreement before converting a residence into a rental.
Two more rules apply to any equity line. The CFPB describes a HELOC as an open-end line you can borrow against repeatedly during a draw period. A repayment period follows, with the full balance often repaid over ten or twenty years. If you sell the property, you generally repay the line in full at that point. A lender can also freeze or reduce a line if the property’s value drops. For a short-term bridge on a value-add project, that risk is manageable. For long-term funding, it is a real consideration.
Line or Cash-Out Refinance? A Decision Table
A HELOC is reviewed on you. A DSCR cash-out refinance is reviewed on the property. DSCR stands for debt service coverage ratio, which compares the monthly rent to the full monthly payment on the property. The right route depends on which side of the file is stronger. The complete DSCR loans guide explains the rent-based side in full.
| Your situation | Likely route |
|---|---|
| Low first mortgage you want to keep | Second-position HELOC |
| Title held by an individual or revocable trust | HELOC is possible |
| Property deeded to an LLC | DSCR cash-out refinance |
| Credit under 700 | DSCR cash-out refinance |
| Need above $500,000 on a rental | DSCR cash-out refinance |
| Heavy first-lien balance, little equity left | Neither; wait or add equity |
On the DSCR side, here is what the network typically looks like. A cash-out refinance on a standard rental tops out around 75% LTV, and about six months of seasoning is the common expectation. For the DSCR loan only, most programs want a credit score near 660, with a 620 floor in parts of the network. The investment HELOC is stricter, with a hard 700 minimum. Reserves commonly run around six months of PITIA, which is principal, interest, taxes, insurance, and any association dues.
Coverage of 1.00 is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, and utilities all sit outside the calculation.
The trade-off is plain. The line keeps your first loan in place and reprices only what you borrow, but it is capped at $500,000 and tightly gated on title and credit. The refinance replaces your first lien, so any cheap first loan is gone. It accepts more titling structures and larger sizes. Neither one is better in general.
Using the Line for the Next Purchase
An equity line works well as down-payment cash. A DSCR purchase loan on the next property is then reviewed on that property’s rent, which makes the two approvals separate. Most purchase files land at 75% to 80% LTV, which means 20% to 25% down, and select high-leverage programs reach 85% LTV with roughly a 700-plus score. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Plan for how the borrowed money looks on paper. The line adds a payment to your debt load, and the lender on the purchase will see it. Some lenders also want drawn funds sitting in your account for a stretch before they count them as down payment. That varies by lender, so ask before you draw.
When Not to Use a Rental Line
Skip the line when the numbers or the structure work against you. Four cases come up often.
- Thin equity. If the first loan already uses most of the 70% ceiling, the line is too small to matter.
- A vacant or gutted property. An automated valuation may not reflect a property under renovation, and a lender may want a secondary valuation or a full appraisal.
- Long-term funding of a long-term asset. The pricing floats and never converts to fixed. A line used as permanent capital leaves you exposed to payment swings.
- Weak cash buffer. Because the line is qualified on the maximum draw, a large line also raises your debt ratio on every other file you apply for.
A broker earns its place here. Because the supply is thin and every lender draws its lines differently, a broker that shops multiple wholesale lenders can match the scenario to the guideline that fits instead of running you through lender after lender.
Key Terms Defined
Second lien: A loan recorded behind your first mortgage, paid second if the property is sold or foreclosed.
Draw period: The stretch when you can borrow from the line, paying interest only on the balance.
Repayment period: The stretch after the draw ends, when the balance is paid down in full on a schedule.
Vesting: The legal way the property is titled, such as an individual, a trust, or an LLC.
Automated valuation: A data-driven estimate of value that stands in for a traditional appraisal.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly cost used in rent-based coverage math.
DSCR cash-out refinance: A new first loan on a rental that returns equity as cash and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Frequently Asked Questions
Can any bank open a HELOC on my rental?
No. Many banks lend against a primary home but not a rental, and the ones that do often limit it to their own footprint. Availability, property types, and entity rules vary a lot, which is why matching the file to the right lender matters more than applying everywhere.
Does a second-position line change my first mortgage?
No. The first loan keeps its balance, term, and payment. The new line is a separate loan secured behind it. Read the first mortgage’s own terms if you have any doubt, but a standard second lien does not rewrite them.
Can I put the line on a rental held in an LLC?
Not on the network’s investment line. Title must sit with you personally or in a revocable living trust. If the property is already in an LLC, you can change vesting first or go with a DSCR cash-out refinance, which can often be written to an LLC subject to program terms.
How much can I borrow against a rental?
On an investment property in the network, the ceiling is 70% CLTV, with a maximum line of $500,000. Your first loan’s balance and any other liens come out of that room first. A line above $500,000 is available only on primary residences.
Does a HELOC qualify on the rent like a DSCR loan?
No. A HELOC is reviewed on your credit, debts, and equity. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. If your personal credit or title falls outside the HELOC limits, the rent-based route may fit better.
