The Quick Read: The best program is a standalone second-lien line that fits your property, your title, and your leverage room. On an investment property, the network we broker through typically caps combined leverage at 70% CLTV, with lines from $25,000 to $500,000. Your first mortgage stays untouched, and your credit profile, vesting, and equity decide the rest.
- A second-lien line leaves your existing first mortgage alone. No refinance is needed.
- On an investment property, typical program ceilings are 70% CLTV and a $500,000 maximum line.
- A 700 credit score is a hard floor for investment lines. Scores above 700 buy eligibility, not extra leverage.
- Title usually has to sit in your personal name or a revocable living trust. An LLC generally cannot hold it.
- Lendmire is a broker, not a lender. Every figure here is subject to lender guidelines and full file review.
Most investors ask the wrong question first. They ask which lender has the best line. The sharper question is which program fits the property you already own. This guide walks through the mechanics step by step.
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 an Investment Property HELOC Behind a First Mortgage?
It is a revolving line of credit secured by a rental you already own, recorded in second position behind your existing mortgage. Your first loan keeps its balance, term, and payment. The new line sits underneath it and draws on the equity left over.
A HELOC (home equity line of credit) is an open-end line. The Consumer Financial Protection Bureau describes it as credit you can borrow against repeatedly, with a draw period followed by a repayment period. Monthly payments are often much higher once repayment begins. That description covers owner-occupied lending in general. Rentals follow tighter rules.
Why would you want one? A second lien lets you keep a first mortgage you like and tap equity next to it. A cash-out refinance would replace that first loan. The line can fund a down payment or rehab on your next property. That new property gets its own separate loan file.
Why Do So Few Lenders Offer It?
Lenders treat rentals as riskier than a primary home, and a second lien sits behind the first in a default. NerdWallet notes that a HELOC on an investment property is possible, but the lender pool is smaller and you can borrow less than you could against your own home. It also says not every lender offers one and qualification is strict.
That scarcity is the case for working through a broker. Lendmire works with a network of wholesale HELOC lenders and matches the scenario to the program. The lenders that write this product differ on property type, title, credit profile, and leverage.
Big banks and large retail lenders often turn away investment-property HELOC requests. Their appetite for rentals tends to be narrow. Wholesale programs built for investors are a different lane.
What Does “Best” Mean for This Product?
The best program is the one that clears six checks for your situation. Run these in order, because the first failure usually ends the search.
| Check | What to confirm |
|---|---|
| Lien position | Line can sit second behind your first |
| Property type | Your rental type is eligible |
| Title | Held by you or a revocable trust |
| Leverage room | CLTV cap leaves room after your first |
| Credit | Score meets the investment floor |
| Line size | Remaining room meets the program minimum |
Notice that rate is not on the list. Pricing is quoted per file and lives in the calculator and the quote itself. Eligibility comes first. A cheaper line you cannot qualify for is worth nothing.
Second Lien or First Lien: Which Position Applies?
The network’s standalone line can take first or second position. Behind an existing mortgage, it is second. If the property is paid off, the line can take first position.
| Factor | Second lien | First lien |
|---|---|---|
| Existing mortgage | Stays in place | None on the property |
| Repaid first in default | Existing first lender | This line |
| CLTV room | Shrinks by your first balance | Full cap available |
| Typical fit | Mortgaged rental | Paid-off rental |
Verify position before you apply. Some products in the market are first-lien only and simply cannot sit behind your mortgage.
How Much Line Can You Get?
Take the program’s CLTV cap times the property value. Subtract every existing lien. What remains is your maximum room, capped by the program’s maximum line.
CLTV is combined loan-to-value. It adds every loan against the property, then divides by the property’s value. A market example shows the arithmetic: on a $1,000,000 property with a $500,000 first and a $200,000 second, CLTV is 70%. That is a market illustration only. On this network, an investment line caps at 70% CLTV, so the same property would leave no room above that second.
Now run it the way it works on your file. Say a property is worth $500,000 and the cap is 70% CLTV. Total debt allowed is $350,000. Three scenarios show how your first mortgage eats the room:
| Existing first (share of value) | CLTV room left | Line outcome |
|---|---|---|
| 40% | 30% of value | Room likely above the program minimum |
| 55% | 15% of value | Room is thin; check the $25,000 minimum |
| 68% | 2% of value | Too little room for this program |
The last row is the trap. If remaining room falls below the program’s minimum line, the product is off the table, no matter how strong your credit is. Another lien, such as a prior second, consumes room the same way.
Also note that at least 75% of the line is drawn at closing. That means CLTV effectively counts most of the line from day one. This is not dry powder you leave untouched.
How Does Underwriting Treat an Investment Line?
Underwriting works step by step. Here is how a file moves through it on the programs we place with.
1. Credit. Investment lines require a 700 minimum, and 700 is a hard floor. A 720 profile reaches the same 70% CLTV as a 700, so credit above 700 buys eligibility, not leverage. The score model is a single-bureau score keyed to the primary wage earner, and the report must be no more than 90 days old at closing.
2. Income. This product is reviewed on personal income. Debt-to-income, or DTI, tops out at 50%. It is 45% for profiles from 600 to 679, though investment already floors at 700. The qualifying payment is the interest-only payment calculated on the maximum draw.
3. Property. Single-family, 2-4 unit, PUD, townhome, and condominium (including non-warrantable) rentals are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
4. Valuation. Investment lines top out at $500,000, and full appraisals start above that. So investment lines usually run on an automated valuation with no traditional appraisal. A higher CLTV may call for a second valuation, and you can request a full appraisal.
5. Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year path for foreclosure and 4 years for deed-in-lieu, pre-foreclosure, or short sale.
6. Exposure. A borrower is limited to three lines. Anyone with more than 15 financed properties is not eligible.
Everything above is subject to lender guidelines and full file review. It is a map, not a promise.
Personal Income or Rent: Which Qualification Route Fits?
This is the fork that decides the outcome. A personal-income HELOC leans on your credit and DTI. A rent-based, DSCR-style second leans on the property’s rent covering its payments. DSCR means debt service coverage ratio, rent divided by the full monthly obligation.
The standalone investment line described here is the personal-income type. If your personal DTI is stretched but the rental performs well, a rent-based second or a DSCR cash-out may fit better. Many DSCR programs start at 1.00 coverage, and a separate select-lender path goes below 1.00 with leverage and terms adjusted. Clearing 1.00 is also not the same as positive cash flow. Repairs, vacancy, management, and capex sit outside the ratio.
For the rental-side route, see Lendmire’s complete DSCR loans guide.
Title and LLC: The Sharpest Catch
Title can end the search before leverage does. The line requires fee simple or leasehold title held by you individually or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
Many investors hold rentals in an LLC for liability reasons. If that is you, the line will not work as is. Re-titling can cost you asset protection and may raise questions with your existing first-mortgage lender. Often the cleaner answer is a DSCR cash-out refinance, which more commonly allows LLC vesting subject to program terms.
Will Your Existing First Mortgage Allow It?
Check four items before you apply:
- Loan documents. Read your first mortgage for any covenant limiting junior liens.
- Prepayment terms. Confirm that adding a second does not trigger a penalty or default.
- Balance and other liens. These set your leftover room.
- Listing status. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
Availability is also narrower than the DSCR footprint. These lines are offered only in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. New Mexico and Ohio apply a CLTV cap that depends on the credit profile.
HELOC, Closed-End Second, or Cash-Out Refinance?
The choice comes down to how much first-lien benefit you keep versus how much cash you can reach.
| Option | Keeps your first | Cash reach | Best fit |
|---|---|---|---|
| Investment HELOC | Yes | Limited by 70% CLTV | Good first mortgage, personal-name title |
| Closed-end second | Yes | Fixed lump sum | Need one set amount |
| DSCR cash-out refinance | No, replaced | Up to about 75% LTV on standard rentals | LLC title, rent-driven file, bigger need |
On a DSCR cash-out, most of the network tops out around 75% LTV on standard rentals, with about 6 months of seasoning commonly expected. Short-term-rental collateral caps at 70% on a cash-out.
What Is the Structure After You Close?
This product floats. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats during both periods and never converts to fixed. At least 75% of the line is drawn at closing.
The typical market HELOC looks similar. Experian reports draw periods that commonly run five to 10 years, followed by a 20-year repayment period. It also notes some HELOCs carry a balloon payment. The payment shock at the end of the draw is the real risk. Interest-only feels cheap until amortization starts.
After closing, the minimum subsequent draw is $1,000, or $4,000 in Texas.
Common Uses and Sequencing
Most investors use the line for a down payment on the next purchase or a rehab. Sequencing matters. You need an existing rental with equity before you can open the line, so it cannot be opened on a property you have not bought yet. Borrow against equity you can leave in place, not equity you hope to create.
A practical pattern: draw on the line for the down payment, then place a DSCR purchase loan on the new property. Purchases typically run 75%-80% LTV, with select high-leverage programs reaching 85% LTV at a 700+ score. The new loan is judged on that property’s rent coverage and your credit profile, subject to lender guidelines.
Remember that the line adds a payment you must carry. Both tests count: enough equity and enough rental coverage on the new deal.
Risks and When Not to Use It
Skip this product in these cases:
- Your rental is titled in an LLC and re-titling would hurt your protection.
- Your first mortgage already uses most of the 70% CLTV room.
- Your score is below 700.
- You need more than $500,000 on an investment property.
- You cannot carry a floating payment through the end of the draw.
Lien stacking is the quiet risk. Each added lien leaves less cushion if values drop or rents slip.
A Brief Tax Note
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. IRS Publication 936 is where the use-of-proceeds rules for home equity debt are laid out.
Key Terms Defined
- CLTV: Combined loan-to-value, meaning every loan on the property added together, divided by its value.
- Second lien: A loan recorded behind your existing mortgage, repaid second in a default.
- Draw period: The stretch when you can borrow from the line, usually interest-only here.
- Repayment period: The stretch after the draw ends, when you repay principal and interest.
- DTI: Debt-to-income ratio, your monthly debts compared with your monthly income.
- Vesting: The legal form in which title to the property is held.
How to Apply: A Document Checklist
Gather these first:
1. Your current first-mortgage statement showing balance and terms.
2. Proof of title and how it is vested.
3. Income documents for personal-income qualification.
4. Homeowners insurance and any HOA details.
5. A list of every financed property you own.
6. Questions for the broker: which programs accept your title, what the leftover room is, and what the draw structure is.

Frequently Asked Questions
Can I get a HELOC on a rental that already has a mortgage?
Yes, through select programs. The line sits in second position and leaves your first mortgage as it is. On an investment property, the network typically caps combined leverage at 70% CLTV, with a $500,000 maximum line and a 700 credit minimum, subject to lender guidelines.
Does a higher credit score get me more leverage?
Not on an investment line. A 720 profile and a 700 profile both reach 70% CLTV. Credit above 700 improves eligibility but does not lift the ceiling. Higher ceilings exist only on primary residences and second homes.
Can my LLC hold title on the property?
Generally no. Title must be held by you individually or by a revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance may be the better route, per program terms.
Do I need an appraisal?
Usually not. Investment lines cap at $500,000, and full appraisals are required only above that amount. Most investment lines run on automated valuation. A higher CLTV may require a secondary valuation, and you can ask for a full appraisal.
Is the line fixed or floating?
It floats. Pricing floats through both the draw and repayment periods and never converts to fixed. Investment lines run a 5-year draw and a 25-year repayment, with at least 75% of the line drawn at closing.
A mortgaged rental with plenty of equity and a personal-name deed is the profile that fits this product best, and an LLC-titled rental belongs on the DSCR side of the table.
