The Quick Read: The program that fits depends on whether your three doors are one triplex or three separate rentals, how much equity each door holds, whether title sits in your own name or an LLC, and whether your personal debt-to-income ratio clears. Lendmire is a mortgage broker, not a lender. It matches the file to a wholesale program that fits those facts.
- On an investment property, the leverage ceiling is 70% combined loan-to-value (CLTV), and the line tops out at $500,000.
- A minimum 700 credit profile applies, and 720 buys no extra leverage on an investment line.
- Title must be in your name or a revocable living trust. An LLC cannot hold it.
- Each line sits on one property. Equity in one door does not help another.
- At least 75% of the line is drawn at closing, so this is not a pure standby line.
What Does “Three Doors” Actually Mean to a Lender?
Three doors can mean one triplex or three separate rentals. The lender treats them differently, and so does the math.
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.
A triplex is one building, one parcel, one lien. It is a 2-4 unit property, which sits inside the eligible property types. A line against it is sized on the whole building’s value.
Three separate rentals are three parcels. Each line is secured by one property at a time. There is no blanket line across a portfolio in this product.
A third case is the house hack. You live in one unit and rent two. That makes the building a primary residence, and primary-residence lines follow a different table from investment lines. The ceiling there is higher than on a pure rental, but only at a 720-or-better credit profile. Do not apply that ceiling to a pure rental.
| Your three doors | Collateral | What changes |
|---|---|---|
| One triplex, all rented | The building | One line, sized on the whole building |
| Three single-family rentals | One door per line | Separate equity test for each door |
| Triplex, you live in one unit | The building as primary residence | Primary-residence table applies |
How Does an Investment Property HELOC Work?
It is a revolving line secured by a rental, in first or second lien position. If the rental has a mortgage, the line sits behind it. If the rental is free and clear, the line is the first lien.
The line does not replace your first mortgage. That is the main reason landlords choose it over a refinance. A low-balance first loan stays in place and the new line sits on top of it.
On an investment property, the draw structure is a five-year interest-only draw followed by a 25-year fully amortizing repayment. No shorter structure exists for investment lines. Pricing floats through both periods and never converts to fixed. A quoted figure always carries its own draw and repayment terms.
At least 75% of the line is drawn at closing. That matters for how you use it. You carry interest-only payments on most of the line from the first day. A line meant to sit unused while you wait for a deal is a poor fit. A line for a defined purchase or renovation fits better.
Lendmire brokers these through select wholesale partners in its network. Two wholesale programs exist, and their terms differ in places. The longer-runway program publishes a minimum later draw of $1,000. The higher-leverage program does not state one. Each figure here applies only within its own program.
How Does Underwriting Treat It, Step by Step?
The deal works through the same checks in the same order. Know them before you apply.
1. Pick the collateral. For a triplex, that is the building.
2. Run the CLTV. Add the existing first-mortgage balance to the requested line. Divide by the property value. The result must sit at or below 70% on an investment property.
3. Check the credit profile. The floor on an investment line is 700. Both the 700 and 720 tiers reach the same 70% CLTV, so a higher score adds eligibility, not leverage. The score model is single-bureau and keyed to the primary wage earner. The report can be no more than 90 days old at closing, and there are no rescores.
4. Test debt-to-income. The maximum is 50%. The payment is calculated on interest-only terms at the maximum draw, not on what you plan to draw. That is a stress test on the full line.
5. Order the valuation. An investment line is capped at $500,000. Full appraisals begin only above that, so an investment line sits in the automated-valuation lane. It commonly closes without a traditional appraisal. You can still ask for a full appraisal. A higher CLTV may also trigger a secondary valuation.
6. Clear title. The property must be held by you or by a revocable living trust. The title report shows whether it is.
7. Check derogatory history. A bankruptcy needs four years of seasoning from discharge or dismissal. A foreclosure needs seven years. A deed-in-lieu, pre-foreclosure or short sale needs four.
Each step is a pass-or-fail gate, and the file stops at the first one it fails.
Where Does Rental Income Fit in a HELOC File?
On this product, personal debt-to-income carries the qualification. That is different from a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
How rent is counted against your debt load is a lender-level detail. Have leases and a rent schedule ready. A triplex with three signed leases presents better than one with a vacant unit and no paper.
Business bank accounts require a 680 minimum for the deposit analysis. The investment floor is already 700. So bank-statement income is never the binding constraint on an investment line. Credit and CLTV decide it.
A landlord whose personal debt load is heavy but whose rents are strong may find the line out of reach. That is when a DSCR cash-out refinance deserves a look. The complete DSCR loans guide explains how that path qualifies.
One Line or Three? A Worked Comparison
Run the numbers on a triplex first. These are modeled assumptions, not market data. Say the first mortgage sits at 55% of the building’s value. A 70% CLTV ceiling leaves room for a line of roughly 15% of value, subject to the $500,000 cap.
Now three separate rentals, again modeled. Door A carries a first mortgage at 40% of value. That leaves up to 30% of value in room. Door B carries a first mortgage at 65%. That leaves only 5% in room, which is thin. Door C has no mortgage, so a line on it sits in first position with up to 70% of value in room.
Door C does the work. Doors A and B cannot lend their unused equity to each other. Each line is sized on its own property.
Three lines on three doors also uses the whole allowance. A borrower is limited to three lines in total, and combined exposure caps depend on the program. A line on your own home counts toward the same three. Landlords who plan to scale should count their lines before they use them up. Lendmire’s piece Best Investment Property HELOC Program for a Landlord Scaling a Rental Portfolio covers that angle.
A borrower owning more than 15 financed properties is not eligible. Three doors sit far below that.
Which Route Fits Which Landlord?
| Route | Qualified on | Leverage anchor | Title |
|---|---|---|---|
| Investment HELOC | Borrower DTI and credit | 70% CLTV, line to $500,000 | Individual or revocable trust |
| DSCR cash-out refinance | Property rent vs. payment | About 75% LTV on standard rentals | LLC allowed, per program terms |
| Bank statement cash-out | Documented deposits | Varies by program | Varies by program |
Use the line when you want to keep a low-balance first mortgage and need a defined amount. Use a DSCR cash-out when your first mortgage is not worth keeping, when title is in an LLC, or when your personal debt load blocks the line. Standard cash-out refinances commonly expect about six months of seasoning.

Key Terms Defined
CLTV: Combined loan-to-value is all liens on the property added together, divided by its value.
Second lien: A loan that sits behind your first mortgage and is paid second if the property is sold.
Interest-only draw: A period where you pay only interest on what you have drawn.
Debt-to-income ratio (DTI): Your monthly debt payments divided by your monthly income.
Automated valuation: A computer-generated property value used in place of a full appraisal.
DSCR: The debt service coverage ratio compares rent to the property’s monthly debt payment.
Where the General Rule Breaks
These edge cases derail files more often than leverage math does.
LLC title. An LLC, corporation, partnership, or an irrevocable, blind or land trust cannot hold title on this line. If your triplex is already deeded to an LLC, you need a vesting change or a DSCR cash-out instead. Business-purpose credit is generally exempt from consumer-credit rules under the eCFR text on exempt transactions. That is a regulatory point. The program’s title rule is separate and still applies.
Property types. Single-family, 2-4 units, PUDs, townhomes and condominiums are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural zoning are not eligible. Modular factory-built homes are eligible on the longer-runway program only.
Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas and Washington.
State caps. New Mexico and Ohio apply a CLTV cap that depends on the credit profile. Texas properties are limited to 10 acres.
Availability. Investment lines are placed only in Lendmire’s 16 full-service states. They are Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia and Washington. That is narrower than the 41-market DSCR footprint. A landlord outside those states should look at DSCR cash-out instead.
A first lender that blocks a second lien. Some first-mortgage servicers restrict junior liens. Check your note before you apply. If it blocks, a cash-out that pays off the first loan is the cleaner route.
Short-term rentals. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
The appraisal form on a full appraisal. If you request a full appraisal on a triplex, the appraiser uses the small residential income property form. Fannie Mae’s appraisal forms guidance lists Form 1025 for 2- to 4-unit properties and Form 1007 for the single-family rent schedule. A triplex gets the 1025.
What Derails These Files in Practice?
Three things come up repeatedly in files like this.
First, title. A landlord assumes the LLC is fine because it works on a DSCR loan. It is not fine here. The file stalls at the title report.
Second, the first-mortgage balance. Landlords estimate equity from memory. The payoff statement shows a different balance, and the CLTV lands over 70%. Pull a current statement before you size the line.
Third, the stress payment. Borrowers test DTI on the amount they plan to draw. The lender tests it on the maximum line. Size the request to what clears the maximum-draw test, not to what you want.
Clearing a debt-to-income test also does not mean the property cash-flows. Repairs, vacancy, management and capex sit outside the number. Size the line against your real operating margin.
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.
The Decision in Practice
The line suits a landlord who wants to keep a low-rate-era first mortgage and has a defined use for the money. The strongest file has a 700-plus credit profile, title in a personal name, a modest first-mortgage balance and a DTI well under 50%.
The line is a weak fit when the first loan is high, title sits in an LLC, or you need more than the CLTV cap allows. It is also a weak fit when you want a standby reserve, since most of it is drawn on day one.
A broker that shops multiple wholesale lenders can match the file to the program whose terms fit. That means confirming the property, credit, title and CLTV before anyone orders a valuation.
Frequently Asked Questions
Can I get a HELOC on a triplex I rent out?
Yes, if the triplex is held in your own name or a revocable living trust. A triplex is a 2-4 unit property, which is an eligible type. The line is capped at 70% CLTV and $500,000 on an investment property, subject to lender guidelines and full file review.
Can I have a line on each of my three rentals?
It is possible, up to three lines in total. The lines are separate, and each is sized on its own property. Combined exposure caps depend on the program.
Can I get one if I live in one of the units?
The building then counts as a primary residence, and primary-residence terms apply. The CLTV ceiling reaches 90% there, but only at a 720-or-better credit profile. Most landlords with a house hack do not reach that tier.
Does my LLC-owned rental qualify?
No. Title must sit with you or a revocable living trust. An LLC-owned property needs a vesting change, or a DSCR cash-out refinance instead, subject to program terms.
Does a higher credit score raise my leverage on a rental?
No. On an investment line, 720 and 700 both reach the same 70% CLTV. A score below 700 is below the floor.
