The Quick Read: Usually up to 70% of the property’s value minus everything already owed against it, with a line between $25,000 and $500,000 and a credit score of at least 700, through select wholesale lenders Lendmire works with and subject to lender guidelines and full file review. The first mortgage eats into that room first. On most rentals, equity runs out long before the dollar cap matters.
- The ceiling is 70% combined loan-to-value, and no credit tier raises it.
- Your existing first mortgage counts against that ceiling.
- Investment lines run from $25,000 to $500,000.
- The minimum credit score is 700, and a 720 score earns the same ceiling.
- Title must sit in your personal name or a revocable living trust, not an LLC.
The Formula: Value, Ceiling, Minus What You Owe
The limit comes from a four-step calculation. First, multiply the property value by 70%. Second, subtract every loan already secured by the property. Third, check the result against the $25,000 minimum. Fourth, check it against the $500,000 maximum. Whatever survives all four steps is the largest line a lender in the network will consider.
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.
Lenders measure leverage with combined loan-to-value, or CLTV. That is all the loans against the property, added together and divided by its value. A first mortgage and a new line both count.
The full line counts, not only the amount you plan to draw. A lender assumes you could borrow all of it, so it sizes risk on the whole limit.
Run the numbers in percentages. Say your first mortgage equals 40% of the property’s value. A 70% ceiling leaves room for a line of up to 30% of value, before the dollar cap applies.
The CFPB’s HELOC booklet shows the same sizing logic on any home. Take a percentage of the appraised value, then subtract what you owe. Investment lines use the same arithmetic with a lower percentage.
Three Scenarios Run in Percentages
Ample equity. Picture a rental owned free and clear. Nothing is owed, so the full 70% of value is open, and the $500,000 cap becomes the limit if the property is worth enough. A first-lien line is possible here, since the structure allows a line in first or second position.
Thin equity. Consider a rental where the first mortgage equals 65% of value. Only 5% of value remains under the ceiling. That sliver may land under the $25,000 minimum line, and then there is no product to write.
No room at all. Now take a rental bought recently with a high-leverage purchase loan. The first mortgage may already sit at or above 70% of value. The room is zero, and appreciation or principal paydown has to open it up before you can apply.
Before you apply, check your first mortgage balance against current value, because it can leave no room under the 70% combined ceiling.
Why Investment Lines Cap Lower Than Home Lines
A rental line is capped lower because lenders see a higher risk of default on a rental than on the home you live in. NerdWallet says you may have fewer lenders to choose from and won’t borrow as much as you could against a primary home.
On this network, occupancy sets the ceiling. The table shows the contrast.
| Factor | Investment property | Primary or second home |
|---|---|---|
| Max CLTV | 70% | Up to 90%, only at 720+ |
| Max line | $500,000 | Primary home can go higher |
| Minimum credit | 700 | Lower floors exist |
| Credit above 700 | Same 70% ceiling | Higher score lifts the ceiling |
A line above $500,000 is available on a primary residence only. An investment line never gets there.
The practical lesson: a score of 720 helps on a primary home, but on a rental it buys no extra leverage. Credit above 700 is an eligibility matter, not a sizing lever.
What Raises the Limit and What Only Gates Approval
Some factors move the number. Others only decide whether you get a number at all.
| Factor | What it does |
|---|---|
| Property value | Raises the limit as value rises |
| First mortgage balance | Lowers the limit dollar for dollar |
| 70% CLTV ceiling | Sets the percentage maximum |
| $500,000 cap | Stops extra equity from adding more |
| $25,000 minimum | Gates approval if room is too small |
| 700 credit score | Gates approval; no extra leverage |
| Title in your name or trust | Gates approval |
| 50% maximum DTI | Gates approval |
Equity after the first lien is the real constraint. A larger dollar cap does nothing for a borrower who has already used up the percentage.
How the Lender Qualifies You
An investment-property line is underwritten on you, not on the rent. The lender reviews your credit and your debts. The rental income is not the test the way it is on a DSCR loan.
Credit comes first. The lender uses one bureau score, keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescoring is not part of the process.
Your debt-to-income ratio (DTI) is the share of monthly income that goes to debt payments. The maximum is 50%. The lender reviews your file on the interest-only payment calculated as if you had drawn the full line. That is stricter than it sounds, because a half-drawn line still gets tested at full size.
NerdWallet’s guide reports lenders asking for at least 20% equity and a DTI between 40% and 50% on investment-property lines, along with cash reserves and proof of long-term tenants. Those are market-wide figures. On this network the equivalent numbers are a 70% CLTV ceiling, which leaves at least 30% of value untouched, and a 50% DTI cap.
Past credit events matter. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, a foreclosure needs seven years, and a deed-in-lieu, pre-foreclosure or short sale needs four.
Valuation is usually automated. Because investment lines cap at $500,000, they sit in the lane where a traditional appraisal is not ordinarily required. You can still request a full appraisal. Some lenders in the wider market order several valuations, so expect that to vary.
Draw Period, Repayment, and the Payment Trap
An investment line runs a 5-year draw period followed by a 25-year fully amortizing repayment period. During the draw period, you generally can borrow up to your limit and repay repeatedly. The CFPB describes a HELOC as an open-end line of credit against home equity, with a draw period followed by repayment.
Two features surprise first-time borrowers.
First, at least 75% of the line is drawn at closing. This product is not a standby credit card for emergencies. You borrow most of the limit on day one and carry it from the start.
Second, pricing floats through both the draw period and the repayment period. It never converts to a fixed structure. The CFPB’s booklet confirms that HELOCs typically carry variable rather than fixed pricing. Your cost can move even while the balance stays flat.
Model the whole life of the line, not the first year. Interest-only payments during the draw period end when repayment begins, and the payment steps up as the balance starts amortizing. If the rental’s cash flow works only during the draw period, the structure is telling you something.
After closing, the minimum subsequent draw is $1,000.
Who Gets a Zero (and What to Do Instead)
Several situations stop the line before the math starts.
- LLC title. An LLC, corporation, partnership, or irrevocable, blind or land trust cannot hold title. This is the sharpest structural difference from a DSCR loan. If the property is already deeded to an entity, you need a vesting change or a different product.
- Property type. Single-family homes, 2-4 unit properties, PUDs, townhomes and condominiums (including non-warrantable condos) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned property are not eligible.
- Portfolio size. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.
- Credit. Below 700, an investment line is off the table, even though lower floors exist on primary homes.
- Location. This product is available only in Lendmire’s 16 full-service states. That is narrower than the 41-market DSCR footprint, which covers 40 states plus Washington, D.C.
That LLC point is a common stumbling block for investors who titled properties in an entity for liability reasons. Many banks outside this network apply similar title limits, which is why a personal-name line and an LLC-owned portfolio often pull in opposite directions.
Using a Home Equity Line on Your Residence to Buy a Rental
This is a different sizing question. A line against your primary home is sized on the home’s value and your debts, not on the rental you plan to buy. Taxstra points out that when a line funds a rental down payment, the HELOC payment counts in your debt-to-income ratio when you qualify for the new mortgage.
The trade-off is leverage. You end up with two obligations, and your home secures the down payment on your rental.
HELOC or DSCR Cash-Out Refinance?
The right product depends on what you want to keep and how you want to qualify.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Qualified on | You: credit and DTI | Property rent coverage |
| Title | Personal or revocable trust | LLC allowed |
| Max leverage | 70% CLTV, investment | Around 75% LTV, standard rental |
| Size | $25,000 to $500,000 | Up to $3,000,000 on standard programs |
| Structure | Floating, 5-year draw | 30-year fixed is the spine |
Keep a low first mortgage and want a revolving line? An investment HELOC fits. Need a bigger lump sum, an entity on title, or a decision that doesn’t turn on your personal DTI? The cash-out route may fit better.
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Across the network, a cash-out refinance tops out around 75% LTV, and about six months of seasoning is the common expectation. Credit floors start at 620 in parts of the network, most programs want around 660, and 700 or better opens the strongest leverage. DSCR loans to LLC-titled borrowers are available subject to lender program eligibility.
One caution applies to DSCR. Clearing 1.00 coverage does not mean positive cash flow. The ratio compares rent to the principal, interest, taxes, insurance and any association dues, and nothing else. Repairs, vacancy, management and capital expenses sit outside the calculation.
Lendmire’s comparison of an equity line against a DSCR cash-out refinance walks through the decision in more detail. The complete DSCR loans guide covers how coverage ratios, leverage and credit interact on that side.
Key Terms Defined
Combined loan-to-value (CLTV): All loans secured by the property, added together and divided by the property’s value.
Draw period: The stretch when you can borrow against the line and make interest-only payments. On an investment line, it lasts five years.
Repayment period: The stretch after the draw period when you repay principal and interest on a fixed schedule. On an investment line, it runs 25 years.
Lien position: Where a loan ranks in line for repayment. A first lien is paid first, and a second lien comes behind it.
Automated valuation: A computer-generated estimate of property value used in place of a traditional appraisal.
Vesting: The way title is held, such as in your name, in a revocable living trust, or in an LLC.
Debt-to-income ratio (DTI): Your monthly debt payments divided by your monthly income.
Frequently Asked Questions
Does a higher credit score raise how much I can borrow on a rental?
No. A 720 score and a 700 score both reach the same 70% CLTV ceiling on an investment property. Above 700, credit improves eligibility but does not buy extra leverage. Seven hundred is a hard floor, and no tier sits beneath it.
What happens if my equity leaves less than the $25,000 minimum?
The line cannot be written. The math has to produce at least $25,000 of room after the first mortgage and the 70% ceiling. If it falls short, you can wait for the balance to drop or the value to rise, or look at a cash-out refinance on a different structure.
Can my LLC borrow against the rental?
Not on this product. Title must be held by you personally or in a revocable living trust. If the property sits in an LLC, the choices are a vesting change or a DSCR cash-out refinance, subject to lender guidelines.
Do lenders count the amount I draw or the whole line?
The whole line counts. A lender assumes you could draw all of it, so combined leverage is measured on the full limit. The program also expects at least 75% of the line to be drawn at closing.
Is the line underwritten on my rental income?
No. It is underwritten on your credit and personal debts, with a 50% maximum DTI calculated on the interest-only payment at the full draw. Rental income drives DSCR products instead, which qualify primarily on property-level rental income covering the payment.
