The Quick Read: A home equity line on a rental is a separate loan recorded behind your existing mortgage, so your first loan keeps its rate, balance and payoff schedule while the new line runs on its own clock, and because many large retail lenders decline rentals, the real work is finding the smaller set of lenders that write them. Banks do not restart anything. The wording in the title describes a product that was never tied to your first mortgage in the first place.
- A line on a rental sits in second position and leaves the first loan alone. A cash-out refinance replaces the first loan.
- Across Lendmire’s wholesale network, an investment-property line tops out at 70% combined loan-to-value, with a $500,000 maximum line and a 700 minimum credit score.
- The line qualifies you personally (credit, debt load, equity). The rent does not carry it the way it does on a DSCR loan.
- Title matters. Lines in the network require an individual or revocable-trust owner, so a rental held in an LLC needs a different product.
- The best lender for your file depends on your property type, credit profile, equity and how the rental is titled.
Why Doesn’t a HELOC Restart My Mortgage Term?
A home equity line is its own contract with its own rate, draw schedule and repayment schedule. Your first mortgage is a different contract with a different lender. Adding a second lien behind it changes neither the first loan’s rate nor its remaining term.
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.
Picture two stacked loans on one rental. The first mortgage sits on the bottom with its original terms. The line sits on top and gets paid second if the property is ever sold or foreclosed. Each has its own payment, and each lender looks only at its own loan.
Compare that with a cash-out refinance. A cash-out refinance pays off the old mortgage and writes a new one, so the rate, term and amortization clock all start over. That is the “restart” investors are trying to avoid. Investors with an existing first loan they like often start here.
One wrinkle is worth knowing. Some products marketed under the name investment property HELOC are really rent-qualified first-lien cash-out refinances. If the product pays off your first mortgage, it restarts your term no matter what the marketing says. Ask the plain question: does my current first mortgage stay in place after closing?
Which Banks Offer an Investment Property HELOC?
Few do, and the list of who does changes often enough that any named roundup goes stale. A better approach is to sort lenders by type and match your file to the type most likely to say yes. NerdWallet’s investor explainer says the pool of lenders is smaller than for a primary-home line and that strict qualification requirements apply. It adds that some lenders restrict these lines by location and by whether the home is rented all year.
| Lender type | Rental HELOC appetite | Typical catch |
|---|---|---|
| Large retail lenders | Many decline rentals | Primary-home focus |
| Community banks, credit unions | Some write second liens on rentals | Local footprint, member rules |
| Portfolio lenders | Case-by-case on their own book | Lower caps, tighter equity rules |
| Wholesale network via a broker | Select lenders write investment lines | Limited states, strict title rules |
A broker adds one thing a single bank cannot. Lendmire arranges lines through select wholesale partners and compares their guidelines against your property, credit and equity. It is never the lender itself. The best match depends on your situation, and a rental that fits one lender’s rules can miss another’s by a single point of credit or leverage.
Availability is also geographic. Lendmire’s equity-line placements run in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA. That is narrower than its DSCR investor footprint of 41 markets, including Washington, D.C.
What Do These Lenders Look For on a Rental?
Across the wholesale network, the investment-property rules look like this, subject to lender guidelines and full file review:
- Credit: 700 is the floor. Scores of 720 and 700 both reach the same 70% ceiling, so a higher score buys eligibility, not extra leverage.
- Leverage: the ceiling on an investment property is 70% combined loan-to-value. Primary residences and second homes can reach higher ceilings, so do not borrow those numbers for a rental.
- Line size: $25,000 to $500,000 on an investment property. Lines above $500,000 are limited to primary residences, so they are never available on a rental.
- Debt load: a 50% maximum debt-to-income ratio, tested on the interest-only payment at the full line amount, not on what you plan to draw.
- Property types: single-family homes, two-to-four-unit buildings, townhomes, planned-unit developments and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered.
- Exposure: up to three lines per borrower, and borrowers with more than 15 financed properties are not eligible.
- Listing status: in several of the 16 states, a property listed for sale, or listed within the past 60 days, is ineligible.
Market-wide figures run tighter or looser depending on the lender. NerdWallet reports that lenders commonly want at least 20% equity. The network’s 70% combined ceiling means you need at least 30% equity after the first mortgage and the line are stacked together.
Because the line is capped at $500,000, valuation usually runs through an automated model rather than a traditional appraisal. A borrower can still request a full appraisal.
How Do You Calculate Your Available Equity?
Multiply the appraised value by the lender’s combined cap, then subtract what you owe on the first mortgage. The remainder is the most the line can be, and the first mortgage balance eats into it first.
Run it in percentages of value. Say the valuation comes in at 100% of what you believe the rental is worth, and the network’s investment ceiling is 70% combined. Your first mortgage balance equals 50% of that value. Your room is 70% minus 50%, which is 20% of the property’s value. The $500,000 line maximum still applies on top of that.
Now test how fragile that is. If the valuation lands 10% lower than you expected, the 70% cap applies to a smaller number, while your first mortgage balance stays exactly where it was. The room shrinks from 20% of your original value to about 13%. A low valuation hurts a thin-equity file much more than a thick one.
Two other items can also reduce your room. An existing second lien counts toward combined leverage. A tax lien that attaches to the property complicates title and may need to be cleared first. Title and lien review is part of every file.
How Does Underwriting Treat the Line, Step by Step?
The lender underwrites you, not the rental’s income. A DSCR loan works the other way. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and the borrower’s personal income plays a smaller role. The complete DSCR loans guide covers that method in full.
For a rental line, the deal works through these steps:
1. Application and credit pull. The score is a single-bureau model keyed to the primary wage earner, and the report cannot be older than 90 days at closing.
2. Title and vesting check. The lender confirms who actually owns the property.
3. Lien review. The lender reads the first mortgage balance and any other liens against the equity math.
4. Valuation. An automated model values the property, or a full appraisal is ordered when requested.
5. Debt-to-income test. Your existing debts, including every mortgage on every financed property, plus the line’s interest-only payment at the maximum draw, must fit within the 50% ceiling.
6. First-mortgage document read. The note and deed of trust are checked for language about additional liens.
Expect to supply a current first-mortgage statement, a homeowner’s insurance declaration, the vesting deed, proof of personal income and your Social Security number. Proof of income and an estimated home value are the minimum, and many lenders also want a tenant in place with documented rental history.
What Does the Line Look Like After You Close?
Investment lines in the network run a 5-year interest-only draw period followed by a 25-year fully amortizing repayment period. The line sits in first or second lien position, and on a rental that already has a mortgage it sits in second position behind that loan. Pricing floats during both periods and never converts to fixed.
Here is the part that surprises people. At least 75% of the line is drawn at closing. So this is not a dormant safety net you open and leave untouched. Lendmire’s piece Banks That Offer an Investment Property HELOC Without Drawing on the Line Right Away goes deeper on that tradeoff.
The CFPB describes the general structure of these products: you borrow up to the limit during the draw period, then enter a repayment period where payments are often significantly higher. In some cases a balance can come due all at once. Plan for the repayment payment, not just the interest-only one. Market draw periods can run up to 10 years, but an investment line in the network uses the 5-year structure.
Does a Second Lien Trigger Due-on-Sale?
For most small residential rentals, a second lien alone does not give your first lender the right to call the loan. A federal statute, the Garn-St Germain Act, bars due-on-sale enforcement when a borrower creates a junior lien that does not transfer occupancy rights, on residential property with fewer than five dwelling units. A legal explainer on the statute walks through the exceptions.
That protection has edges, and the edges are where investors get hurt:
- It does not reach buildings with five or more units.
- It does not protect a transfer of title into an LLC. A law-firm article on title transfers notes that no protections apply when title to a mortgaged property moves into an LLC or similar vehicle.
- It limits due-on-sale calls, but it does not erase other contract terms. Your first mortgage can still carry additional-lien covenants or a prepayment penalty.
Read the first mortgage note and deed of trust before you apply, and ask the servicer in writing whether a junior lien is permitted. An existing DSCR first mortgage deserves the same check. If its documents forbid a junior lien, replacing that first loan with a cash-out refinance is usually the cleaner route.
Where the General Rule Breaks
The “keep your first mortgage” logic holds in most cases. These are the named exceptions.
LLC-held rentals. Lines in the network require title held by the individual borrower or a revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title. That is the sharpest structural difference from a DSCR loan. Moving a mortgaged rental out of an LLC to qualify can set off the due-on-sale problem described above, so retitling is a decision to take to your attorney first.
Larger buildings. The network’s investment lines cover one-to-four-unit properties. A five-unit building falls outside both the line programs and the statute’s protection.
Higher-leverage or larger needs. A line above $500,000 is for primary residences only. A rental investor who needs more cash than the 70% combined cap allows looks at a different product.
Rate-gap situations. If your existing first mortgage is much cheaper than current market loans, keeping it and adding a line often makes sense. If it is not, a refinance may improve your overall terms. A BiggerPockets thread shows investors arguing that exact point.
Variable pricing. The line floats and never converts to fixed. That is fine for short-duration needs such as a renovation. It is a harder fit for a long-term, unknown-term need.
HELOC, Home Equity Loan, or DSCR Cash-Out?
Which one wins depends on whether you want to keep the first mortgage, whether the rental sits in an LLC, and how much cash you need.
| Factor | HELOC | Home equity loan | DSCR cash-out |
|---|---|---|---|
| First mortgage | Stays in place | Stays in place | Replaced |
| Reviewed on | You personally | You personally | Rent coverage |
| LLC title | Not eligible | Often not eligible | Subject to program terms |
| Payout | Revolving line | Lump sum | Lump sum |
| Pricing | Floats | Usually fixed | Set at closing |
A DSCR cash-out refinance on a standard rental tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. It replaces your first loan, so you take on a new term. Qualification runs primarily on the property’s rental income covering the payment, subject to lender guidelines. The DSCR number is rent divided by principal, interest, taxes and insurance only. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy and management sit outside the calculation.
A rough decision frame: choose the line when you like your first mortgage, own the rental personally, have 30% or more equity after the stack and want flexibility. Choose the DSCR cash-out when the rental is in an LLC, your personal debt load is already stretched by a large portfolio or you need a larger sum.
A line also changes your next application. Its payment counts in your debt-to-income ratio when you apply for another loan, and any new first lender has to deal with the junior lien. Foreclosure exposure rises too, because two liens now secure the rental and the line is paid second.
Questions to Ask Before You Apply
Use this list with any lender, bank or credit union:
1. Do you write lines on non-owner-occupied one-to-four-unit properties in my state?
2. Do you restrict lending by location or by whether the home is rented year-round?
3. What is the maximum combined loan-to-value for an investment property, and what credit score does it require?
4. Does the line sit in first or second position on my property?
5. What percentage of the line is drawn at closing, and what is the minimum draw afterward?
6. How long is the draw period, and what does repayment look like afterward?
7. Will you value the property with an automated model or a full appraisal?
8. Can an LLC or trust hold title, and which kinds?
9. How does the line payment count in my debt-to-income ratio for later purchases?
10. How do I confirm your guidelines are current?
That last one matters because lender appetite changes. The most reliable check is a written answer from the lender on your specific property.
Key Terms Defined
Open-end line of credit: a revolving loan you can borrow against repeatedly up to a limit.
Lien position: the order in which lenders get paid if a property is sold or foreclosed, with first position paid first.
Combined loan-to-value (CLTV): all loans secured by the property added together, divided by its value.
Draw period: the stretch when you can borrow from the line, usually with interest-only payments.
Repayment period: the stretch after the draw ends, when you can no longer borrow and the balance amortizes.
Due-on-sale clause: a first-mortgage term that lets the lender demand the full balance if the property is transferred.
Automated valuation: a computer-generated value estimate used in place of a traditional appraisal.
Vesting: how title to the property is legally held, such as an individual, a trust or an LLC.
Frequently Asked Questions
Can I get a HELOC on a rental I hold in an LLC?
Not through the lines in Lendmire’s wholesale network. Title must be held by the individual borrower or a revocable living trust. A rental already deeded to an LLC needs either a vesting change, which carries due-on-sale risk on the first mortgage, or a DSCR cash-out refinance, subject to lender program eligibility.
Will the line change the rate on my first mortgage?
No. The line is a separate loan, so your first mortgage keeps its existing rate, balance and remaining term. Only a cash-out refinance, or a product that pays off the first loan, replaces them.
How much can I borrow against a rental?
On an investment property in the network, the ceiling is 70% combined loan-to-value, up to a $500,000 maximum line, with a 700 minimum credit score. Your first mortgage balance counts toward that 70%, so the available room is whatever remains. Every figure is subject to lender guidelines and full file review.
Does the rent need to cover the payment?
Not the way it does on a DSCR loan. A line is underwritten on your credit, debt-to-income ratio, equity and title. Some lenders also want a tenant in place with documented rental history, but the rent is not the qualifying basis.
Can I use the line to buy my next property?
You can use the proceeds toward a purchase, since the line is secured by a property you already own. The line cannot be opened against a property you do not own. Remember that at least 75% of the line is drawn at closing, so plan that cash deliberately.
