The Quick Read: The right program is the one your property value, title, and credit can support. An investment line on this network caps at 70% combined loan-to-value (CLTV), and your $500,000 first mortgage comes off the top dollar for dollar before any line exists. That math means the property generally has to be worth more than about $714,000 before a line appears at all. When it falls short, a DSCR cash-out refinance is the usual fallback.
- Investment lines on the network cap at 70% CLTV and a $500,000 maximum line, with a 700 credit minimum.
- Your existing first mortgage stays in place. The new line sits behind it as a second lien, or in first position if the property has no mortgage.
- Title must be in your personal name or a revocable living trust. An LLC cannot hold title on this product.
- Lines at or below $500,000 usually run on an automated valuation, with no traditional appraisal.
- Lendmire arranges these lines in its 16 full-service states only, narrower than its DSCR footprint.
What the Program Looks Like on This Network
Lendmire is a mortgage broker, not a lender. It places files with select wholesale HELOC lenders and matches each scenario to the program that fits. No single “best” program exists. The best fit for your situation depends on the property’s value, how it is titled, your credit profile, and how much cash you need.
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.
Here is the investment-property profile, subject to lender guidelines and full file review.
| Factor | Investment-property line |
|---|---|
| Maximum CLTV | 70% (720+ and 700+ both reach it) |
| Credit minimum | 700, a hard floor |
| Line size | $25,000 up to $500,000 |
| Structure | 5-year draw, then 25-year repayment |
| Valuation | Usually automated |
| Title | Individual or revocable living trust |
Two details deserve attention. First, a score above 700 buys eligibility, not extra leverage. A 760 borrower gets the same 70% ceiling as a 700 borrower. Second, the line size ceiling is firm. Lines above $500,000 exist on this network, but only for primary residences. They are not available on rentals.
How the $500K Mortgage Eats Your Line
The first mortgage is a fixed subtraction. The formula is simple: property value × 70% − your existing mortgage balance = your maximum line. The line is then capped at $500,000.
The CFPB booklet on home equity lines describes the same method. A lender takes a percentage of the appraised value and subtracts what you owe. Only today’s market value counts in that math. The BiggerPockets HELOC glossary makes the same point: not your purchase price, and not a value you hope the property reaches after renovation.
Run it with a $500,000 balance. Seventy percent of value has to clear $500,000 before a single dollar is left. Dividing $500,000 by 0.70 gives the break-even value, a little over $714,000. Plain arithmetic, not a market statistic.
| Property value | What the formula gives |
|---|---|
| Below about $714,000 | No line. 70% of value is under your balance |
| About $714,000 to $750,000 | A sliver, usually below the minimum line size |
| About $750,000 to $1.43 million | A line that grows 70 cents per added dollar of value |
| About $1.43 million and up | The $500,000 cap binds |
The $750,000 mark is where the formula first reaches the $25,000 minimum line. Above that, every extra $100,000 of value adds $70,000 of room, until the cap takes over near $1.43 million.
Three things shrink the result further:
- A second lien. CLTV counts every recorded loan on the property, so an existing second mortgage or tax lien comes out of the same 70%.
- A recent high-leverage refinance. If you cashed out near the ceiling last year, there is often no room left.
- A valuation that comes in low. The formula uses the valuation, not your opinion of the property.
This is why a large first mortgage changes the answer. A $500K balance on a $900,000 property leaves a workable line. The same balance on a $650,000 property leaves nothing, no matter how strong your credit is. Lendmire’s piece on how far investment-property HELOC limits stretch with a $500K existing mortgage walks through the limits in more detail.
Who Qualifies
Qualifying on this product is personal, not property-based. That is the sharpest contrast with a DSCR loan. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. An equity line looks at you: credit, debt-to-income, and the property’s value.
Credit. The investment floor is 700. The lender pulls a single-bureau score keyed to the primary wage earner, and the report must be no more than 90 days old at closing. No rescores.
Debt-to-income. The ceiling is 50%. The lender calculates it on the interest-only payment for the maximum draw, not on what you plan to borrow. An investor with a big portfolio and thin personal income can hit this wall even with plenty of equity.
Title. Fee simple or leasehold, held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead. Retitling can affect your existing mortgage, insurance, and liability setup, so sort that out before applying.
Property type. Single-family, 2-4 units, PUD, townhome, and condominium (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural properties are not.
Portfolio size. You are limited to three lines. An investor with more than 15 financed properties is not eligible.
Listing status. In Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington, a property listed for sale, or listed within the past 60 days, is ineligible.
Location of the lender relationship. Lendmire arranges these lines only in its 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.
How the Line Actually Works After Closing
An open-end line works differently from a standard mortgage. As the CFPB’s HELOC explainer puts it, you can borrow repeatedly against your equity during a draw period, then enter a repayment period in which borrowing stops. Investment lines here follow a 5-year draw followed by a 25-year fully amortizing repayment.
Here is the catch most investors miss. At least 75% of the line is drawn at closing. This is not an “open it and leave it unused” product. Pricing floats during both the draw and the repayment period and never converts to a fixed structure. A later draw after closing typically carries a minimum of around $1,000.
Valuation is usually light. Because an investment line caps at $500,000, and full appraisals begin only above that, these files commonly close on an automated valuation. A higher CLTV may trigger a secondary valuation. You can also request a full appraisal. Do that if you recently renovated, because an automated model may not give credit for the work.
One tax sentence, and only one: tax treatment varies; consult a qualified professional before relying on any deduction.
Which Route Fits Your Situation?
“Best” depends on facts you control. This table maps common situations to the route that tends to fit, subject to lender guidelines and credit approval.
| Your situation | Likely best route | Why |
|---|---|---|
| Value well above break-even, personal title, 700+ | Investment HELOC | Keeps your first mortgage untouched |
| Value near or below break-even | DSCR cash-out refinance | The equity line has no room |
| Property held in an LLC | DSCR cash-out refinance | LLC title is not allowed on the line |
| Credit under 700 | DSCR cash-out refinance | 700 is a hard floor |
| Need more than $500,000 | DSCR cash-out refinance | Investment lines cap at $500,000 |
| Heavy portfolio, thin personal income | DSCR cash-out refinance | DTI can block the line |
This is the broker’s real value. A bank sells you its own product. A broker with several wholesale lenders can see which program your file fits before you apply, and can steer you to the DSCR route when the equity line cannot work.
HELOC vs. Cash-Out Refinance vs. DSCR Cash-Out
Three tools reach the same equity. They treat your $500K first mortgage very differently.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| What is underwritten | You: credit, DTI, value | The property’s rent vs. payment |
| First mortgage | Stays in place | Paid off and replaced |
| Max leverage | 70% CLTV | About 75% LTV on a standard rental |
| Title | Individual or revocable trust | LLC possible, per lender terms |
| Structure | Variable, 5-year draw | Typically a 30-year fixed spine |
A cash-out refinance replaces the whole $500,000 balance, not just the new money. If your first mortgage is the one thing worth protecting, the HELOC wins on that point. If you want one clean loan and a larger equity pull, the cash-out wins. For the second path, see Lendmire’s complete DSCR loans guide.
A few typical DSCR cash-out guidelines across the network, all subject to lender review:
- Cash-out on a standard rental tops out around 75% LTV. On short-term-rental collateral, it is about 70%.
- About six months of seasoning is the common expectation.
- Most programs want a credit score around 660. A 620 floor exists in parts of the network, and 700+ unlocks the strongest leverage.
- Reserves vary by lender, leverage, and loan size, commonly around six months of PITIA (principal, interest, taxes, insurance, and any HOA dues).
- Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
One caution. Clearing 1.00 coverage does not mean positive cash flow. Repairs, vacancy, management, and utilities sit outside the calculation.
Edge Cases Where the Rule Breaks
Using your primary home’s equity instead. Some investors skip the rental and borrow against their own residence. Primary-residence lines follow a different ceiling table. A top tier of 90% CLTV exists, but only at a 720 or better credit profile. Lines above $500,000 are primary-residence only, require a 700 or better credit profile (720 on the longer-runway structure), cap at 75% CLTV, and require a full appraisal. That is a different loan with different risks, because your home is the collateral.
Converting a home to a rental. Investors often open a line before moving out, while the property is still their primary residence. That is a different occupancy tier. Before you convert, confirm the line’s terms allow renting the property, because some lenders restrict it.
A line that depends on an old valuation. If your property was recently renovated, ask about a full appraisal. An automated valuation may trail what you did to the place.
An LLC-held rental. The product cannot go forward as titled. Your choices are a vesting change or a DSCR cash-out. Deeding a rental out of an LLC raises questions about liability protection, so many investors take the DSCR route instead.
Stacked equity lines. The three-line limit and exposure caps apply across your whole portfolio, not property by property.
Pre-Application Checklist
Pull these before anyone asks:
1. Your current first mortgage balance (the payoff figure, not the original loan).
2. A realistic current value for the property.
3. A list of any other liens, second mortgages, or recorded judgments.
4. Proof of how the property is titled.
5. Your credit profile, including score and tradelines.
6. Income documents and a debt list, since DTI is tested on the maximum draw.
7. Your count of financed properties and existing equity lines.
With those in hand, the sizing math takes about a minute. Run it before you pay for anything.
The Risk Side
A fully drawn variable line behaves like a variable mortgage. The CFPB notes that you must repay when the draw period ends. If pricing moves up, so does your payment, and the line sits behind a $500,000 first loan. Stress-test the payment at the full draw, not at the draw you intend. Remember that 75% of the line is drawn at closing.
Then there is the cushion. A line sized at the 70% ceiling leaves thin equity if values soften. (Equity that looks generous at 70% CLTV can disappear faster than people expect.) The honest decision usually comes down to this: do you need the line, or do you need cash for one purchase? If it is one purchase, a cash-out may fit better.
Key Terms Defined
CLTV (combined loan-to-value): All loans secured by the property, added together, divided by its value.
Second lien: A loan that sits behind your first mortgage in line for repayment.
Draw period: The stretch of time when you can borrow against the line.
Automated valuation: A computer-model estimate of value, used instead of a traditional appraisal.
DSCR (debt service coverage ratio): Monthly rent divided by the monthly payment (PITIA).
Vesting: How title to the property is legally held, such as personally, in a revocable trust, or in an LLC.
Frequently Asked Questions
Can I get an investment property HELOC if my first mortgage is $500,000?
Yes, if the property’s value is high enough. Seventy percent of the value must exceed $500,000 by at least the minimum line size. That generally means a property worth roughly $750,000 or more. Below about $714,000, there is no room. Credit, title, and the other eligibility rules still apply, subject to lender guidelines.
What is the maximum line on an investment property?
The maximum is $500,000, and it applies only on the investment tier at 70% CLTV. A line above $500,000 is available only on primary residences. A score above 700 does not raise the investment ceiling.
Can an LLC hold title on the property?
No. This product requires title in your name or a revocable living trust. If the rental is held in an LLC, the practical alternative is a DSCR cash-out refinance, subject to program terms.
Do I need a full appraisal?
Usually not. Lines at or below $500,000 ordinarily run on an automated valuation. A higher CLTV may require a secondary valuation, and you can request a full appraisal anytime. That is worth doing after a renovation.
What if the HELOC math doesn’t work?
Then a DSCR cash-out refinance is the common next step. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It replaces your first mortgage, so weigh that against keeping the loan you have.
