The Quick Read: An investment property HELOC is not capped by the agency loan limit, because it is a non-agency line sized by combined loan-to-value, credit, and a fixed line cap, so qualifying past conventional limits means clearing a 700 credit floor, staying within 70% combined leverage, and holding clean title in your own name or a revocable trust. Every figure below is subject to lender guidelines and a full file review.
- On an investment property, the line tops out at 70% combined loan-to-value (CLTV), and 700 is a hard credit floor.
- Lines run from $25,000 to $500,000 on a rental. Larger lines exist only on a primary residence.
- This product is reviewed around personal income and debt, with a 50% maximum debt-to-income ratio. It does not qualify on rent.
- LLCs cannot hold title. A rental already in an LLC needs a different structure, usually a DSCR cash-out.
What an Investment Property HELOC Actually Is
An investment property HELOC is a revolving line of credit secured by a rental you already own. On Lendmire’s wholesale network it is a standalone line in either first or second lien position. You can add it behind a mortgage you want to keep, or place it first on a paid-off rental.
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.
The rental can be a single-family home, a 2-4 unit building, a PUD, a townhome, or a condominium, including a non-warrantable one. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not eligible.
Investment lines run a 5-year interest-only draw period followed by a 25-year fully amortizing repayment period. At least 75% of the line is drawn at closing. Pricing floats through both periods and never converts to fixed. After closing, the minimum subsequent draw is typically $1,000.
NerdWallet notes that rental-property HELOCs come from a smaller pool of lenders, allow less borrowing than a primary-home line, and carry strict qualification. That matches what a broker sees. Large retail lenders often decline the product entirely, so access is the first hurdle.
Key Terms Defined
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value.
Lien position: Your place in line to be repaid. A first lien is paid before a second lien.
Draw period: The stretch when you can borrow from the line and pay interest only.
DTI (debt-to-income): Your monthly debts divided by your monthly income.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s full monthly housing payment, which means principal, interest, taxes, insurance, and any HOA dues. Lenders call that payment PITIA.
Vesting: How title to the property is held, such as in your personal name, a trust, or an LLC.
Seasoning: The waiting period a lender wants between two events, such as owning a property before borrowing against it.
How Underwriting Treats It, Step by Step
Underwriting on this line runs in a fixed order: lien position, equity, credit, income, property, and title. A miss at any step ends the file, so the order matters. Here is how each test works.
Step 1: Choose the lien position. If you want to keep a first mortgage, the new line goes behind it as a second lien. If the rental is paid off, the line sits first. The collateral must be a rental you already own. The property you are trying to buy cannot secure the line.
Step 2: Test the equity. The ceiling on an investment property line is 70% CLTV, with no tier above it. Add your first mortgage balance and the requested line, then divide by value.
The math is easy to run yourself:
- If your first mortgage sits at 50% of value, room for a line is up to about 20% of value.
- At a 60% first mortgage, room shrinks to about 10% of value.
- At 70%, there is no room at all.
Two other limits can bind before the percentage does. The line must meet the $25,000 minimum, so a thin sliver of equity on a modest property may not produce a usable line. On a high-value paid-off rental, the $500,000 cap binds before 70% does.
Step 3: Test the credit. The floor is 700. Scores of 720 and 700 both reach the same 70% CLTV, so a higher score buys eligibility rather than extra leverage. The lender pulls a single-bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not allowed.
Mortgage history matters too. A bankruptcy needs 4 years of seasoning from discharge or dismissal. A foreclosure typically needs 7 years. A deed-in-lieu, pre-foreclosure, or short sale needs 4.
Step 4: Test the income. This is where many DSCR-minded investors are surprised. The line is reviewed on your personal income and debts, not on the rent. The maximum DTI is 50%. It drops to 45% for credit profiles from 600 to 679, and a ratio above 45% requires a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not the amount you plan to use.
Self-employed borrowers can qualify on documented income under the applicable program, subject to lender guidelines. Lendmire’s piece How to Qualify for an Investment Property HELOC Without Income Verification walks through that path.
Step 5: Value the property. Because an investment line caps at $500,000 and full appraisals begin only above that, these lines sit in the automated valuation lane. That usually means no traditional appraisal. A higher CLTV may call for a secondary valuation, and you can always request a full appraisal.
Step 6: Clear the title. Title must be held by you as an individual or by an inter vivos revocable living trust. This is the sharpest structural difference from a DSCR loan, and it trips up more rental owners than any other rule.
Where Conventional Loan Limits Fit (and Don’t)
The conventional loan limit is an agency-purchase rule, and it does not size a HELOC. The Federal Housing Finance Agency sets the conforming loan limit, which is the maximum original loan amount Fannie Mae and Freddie Mac may buy. The one-unit baseline is currently $832,750, and the ceiling in high-cost areas is $1,249,125. Loans above the limit are called jumbo, as HousingWire explains.
The limit is announced each late November and takes effect January 1. A new figure is not official until FHFA publishes it. Four-unit limits run higher than the one-unit figures.
This matters for one reason. A HELOC is not an agency product, so it has no conforming ceiling. Its limits come from its own program: CLTV, credit, the line cap, and title. “Past conventional limits” is really three different problems:
| Your problem | Does an investment HELOC help? | What often fits instead |
|---|---|---|
| Loan is above the dollar limit | Only up to the line cap | DSCR cash-out or purchase |
| Income or DTI doesn’t fit agency rules | Partly (50% DTI max) | DSCR loan on rent |
| Too many financed properties | Up to 3 lines, 15 properties | DSCR loan |
The timing point is practical. A loan near the line can be jumbo one year and conforming the next. A limit increase can change which structure fits, so check the current figure before you choose.
Structures and Variations Worth Knowing
The same label can describe quite different products, so ask which structure you are looking at. Three variations come up most often.
Second lien behind a loan you keep. This is the main reason investors choose a line. You tap equity without touching the existing first mortgage. It works best when that first loan is small relative to value.
First lien on a paid-off rental. With no mortgage, the whole 70% CLTV is available, up to the $500,000 cap. The line becomes your only debt on the property.
A line on your own home. A primary residence or second home qualifies for more leverage and bigger lines. A primary-residence line can run up to $750,000, and the ceiling there can reach 90% CLTV, but only at a 720-or-better credit profile. Above $500,000, the credit requirement is 700 or better (720 on the longer-draw structure), the cap is 75% CLTV, and a full appraisal applies. None of that carries over to a rental.
Borrowing against your home also puts the house you live in at risk if the investment goes wrong.
The numbers also look different elsewhere in the market. NerdWallet reports that rental HELOCs commonly require 20% equity, versus 15% on a primary home. On Lendmire’s network, an investment line is capped at 70% CLTV.
Where the Rule Breaks
Most files follow the order above. These edge cases are where they fail.
The rental is in an LLC. Many investors hold rentals in an entity for liability reasons. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title on this line. You would need a vesting change or a DSCR cash-out instead. Moving title can have its own consequences, so check with your attorney and lender first.
Your score is under 700. There is no tier beneath the floor. A 680 score can work on other products, but not on an investment line.
You own a lot of financed property. A borrower is limited to three lines. Someone with more than 15 financed properties is not eligible. Combined exposure caps apply as well.
Your first mortgage is large. If the first loan already eats most of the 70%, a line leaves nothing to draw. If that first mortgage is not worth keeping, replacing it through a cash-out refinance can make more sense than stacking a second loan.
You want to use the property being bought. The line cannot secure a property you are purchasing. It supplies cash from a rental you already own. A separate loan buys the new one.
Stacked leverage. A second lien reduces remaining equity. That matters later if you want to refinance the first loan or sell.
Recently listed property. A property listed for sale, or listed within the past 60 days, is ineligible in a handful of states. The line is also available only in the 16 states where Lendmire offers full-service lending.
The property type doesn’t fit. Manufactured homes, log homes, and barndominiums are not offered, either on the HELOC or on DSCR loans through the network.
When a DSCR Loan Takes Over
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It is a different tool, not a bigger HELOC. Lendmire arranges DSCR financing in 40 states plus Washington, D.C., a wider footprint than the HELOC.
Here is how the two compare on the points that matter past the limits:
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| Reviewed on | Personal income and DTI | Rent against PITIA |
| Leverage ceiling | 70% CLTV | Around 75% LTV, standard rentals |
| Size | $25,000 to $500,000 | Up to $3,000,000 on standard programs |
| Title | Individual or revocable trust | LLC allowed* |
| Existing first mortgage | Stays in place | Gets replaced |
*Subject to lender program eligibility.
Most DSCR cash-out files want about six months of ownership first. Coverage of 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Credit typically starts around 660, and 700 or better unlocks the strongest leverage tiers. Reserves vary by lender, leverage, and loan size, and are commonly around six months of PITIA.
Keep one caution in mind. A DSCR of 1.00 or higher does not mean positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it.
Lendmire’s complete DSCR loans guide covers the rest of the program.
How the Decision Usually Plays Out
The right choice follows from three facts: how much equity you hold, how the rental is titled, and how much cash you need.
Take an investor with a modest first mortgage, a 740 score, and a rental in her own name. A second-lien line is the clean fit. She keeps her first loan and draws only what she needs.
Now take an investor whose rentals all sit in an LLC. The line is off the table unless he changes vesting. A DSCR cash-out is the more natural path, and he can size it to the rent’s coverage.
Finally, consider an owner with a paid-off rental worth a lot and a need for more than $500,000. The line cap binds first. A DSCR cash-out, which runs higher in size, is the more realistic fit.
Equity and rent coverage are separate tests. The strongest files clear both, and the right product is the one that matches whichever test you pass best.

Frequently Asked Questions
Can I get an investment property HELOC if my rental is in an LLC?
Not directly. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on this line. Title must sit with you as an individual or in a revocable living trust. A vesting change is possible, or a DSCR cash-out can work instead, subject to lender program eligibility.
Can I use the line for a down payment on my next rental?
Yes, because the line is secured by a rental you already own, not by the one you are buying. The new purchase loan will still review where your down payment came from, so borrowed funds are disclosed. Because it attaches to a different property, the line typically stays out of the new property’s coverage ratio.
Will I need an appraisal?
Usually not. Investment lines are capped at $500,000, and full appraisals begin only above that, so most files use automated valuation. A higher CLTV may call for a secondary valuation, and you can request a full appraisal at any time.
How many lines can I hold, and does equity pool across rentals?
A borrower is limited to three lines, and anyone with more than 15 financed properties is not eligible. Each line attaches to a single property. Equity in one rental does not carry over to another.
Does clearing the conventional loan limit make a HELOC easier to qualify for?
No. The limit governs which loans agencies can buy, not how a HELOC is sized. A HELOC is reviewed on credit, DTI, CLTV, and title. Credit and equity still determine the outcome.
