The Quick Read: It depends on equity, credit and lien position: through select programs, a second-lien line can reach 70% combined loan-to-value up to $500,000, a first-lien line on a mortgage-free rental can reach 75% of value at the top credit tier, and the existing mortgage balance comes out of that ceiling before any room is left, subject to underwriting.
- The formula is the program’s ceiling times the property value, minus every lien already on the rental, then capped by the maximum line size.
- A second lien needs a 720 credit score or better, and a first lien needs 700 or better.
- Rent qualifies the line at a minimum 1.10x coverage on a stress payment across the whole credit limit.
- A recent purchase with a high first mortgage can leave little or no room at all.
How Is the Maximum Line Calculated?
The maximum line is the lender’s leverage ceiling applied to the property’s value, minus all debt already secured by the property, and then limited by the program’s dollar cap. Three numbers decide it: value, ceiling, and existing liens.
Start with the ceiling. On a second lien, which sits behind the first mortgage you keep, the ceiling is a combined number. It counts the first mortgage balance plus the full line limit, divided by value. Across the wholesale network Lendmire works with, the second-lien ceiling is 70% combined loan-to-value (CLTV) at a 720 credit score or better, on lines up to $500,000. Below 720 there is no second-lien option on this program. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
A first lien works differently. It exists only on a rental with no mortgage, so the ceiling is plain loan-to-value (LTV), and it steps up with credit score and line size.
- 740 or better: up to 75% LTV on lines to $500,000.
- 700 to 739: up to 70% LTV on lines to $500,000.
- Lines above $500,000, up to $1,000,000: 65% LTV at 720 or better. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
That last tier surprises many owners. A bigger line comes with a lower percentage, so the largest lines are not the most leveraged ones.
Two more points trim the number. The test counts the entire line limit, not just the amount you plan to draw. A declining-market flag on the property lowers the ceiling by 5 points, and a Philadelphia property carries a ceiling 10 points lower.
NerdWallet makes the broader point that an investment-property HELOC is possible but not offered by every lender. It also notes that lenders see higher default risk on rentals, which is why leverage runs below what an owner-occupied home line allows.
What Does the Rent Have to Prove?
The rent has to cover a stress payment on the whole line at 1.10x or better. The line qualifies primarily on property-level rental income covering that payment, subject to lender guidelines. Tax returns, W-2s, pay stubs and a personal debt-to-income calculation are not part of the file.
Here is how the coverage test works. Gross monthly rent is divided by a fully amortizing payment on the entire credit limit, figured at the start rate plus 2 percentage points. That is deliberately harsher than what you will actually pay during the interest-only draw period. Only principal and interest sit in that qualifying payment, so taxes and insurance stay out of it.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease must be in place. A two-to-four-unit property can have at most one vacant unit.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. Lendmire’s network does not publish a second-lien coverage formula, so the lender’s own math governs.
Since the loan is business-purpose, the LLC can stay on title, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line do not have to be the borrowers on the first mortgage.
Worked Examples in Percentages of Value
The table below uses shares of value instead of dollars, so you can swap in your own number. “Room” is the ceiling minus the first mortgage, expressed as a share of value, before the dollar cap applies.
| Scenario | Credit | Ceiling | Room as share of value |
|---|---|---|---|
| No mortgage, first lien | 740+ | 75% LTV | Up to 75% |
| No mortgage, first lien | 700-739 | 70% LTV | Up to 70% |
| First mortgage at 45% of value | 720+ | 70% CLTV | 25% |
| Same, declining-market flag | 720+ | 65% CLTV | 20% |
| First mortgage at 75% of value | 720+ | 70% CLTV | — |
Picture an investor holding a rental with a first mortgage equal to 45% of value and a 740 score. The second lien can reach 25% of value, provided that figure stays inside the $500,000 cap. If the property sits in a flagged declining market, the same investor drops to 20%. On higher-value rentals the dollar cap tends to bind before the percentage does. On lower-value rentals the percentage binds first, and the $50,000 minimum line can matter too.
Now consider a recent purchase at leverage above the 70% combined loan-to-value ceiling for a second lien. The first mortgage is already above that ceiling, so there is nothing to borrow. Equity has to build through paydown or appreciation first. That owner is also inside the seasoning window described below.
An owner with no mortgage has the most room. Even then, a 720 score with a first lien lands in the 70% tier, while 740 reaches 75%. Twenty points of credit can be worth five points of leverage.
What Shrinks Your Number?
Credit tier, lien position, property type, valuation and borrower exposure all move the result. Check them in this order, because the first failure ends the search.
1. Seasoning. A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date).
2. Credit. The tier is set by the lender’s own credit report. The file also needs no 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
3. Property type. Single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums are eligible property types. The leverage tiers above govern every type. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use property, a property listed for sale in the prior 2 months, and a property with a solar lien are not eligible.
4. Valuation. Lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted, and a low value shrinks the line directly.
5. Borrower. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not. Exposure is limited to 5 loans or $2,500,000 per borrower with the program.
No reserves and no cash to close are required on this program. Other lines you may see advertised often ask for reserves, so compare on that point.
How Do the Draws and Repayment Work?
You pay interest only on what you have drawn for 5 years, then the balance amortizes over a 25-year repayment period, with a 30-year maturity and a variable rate. The CFPB’s overview of home equity lines describes the same revolving structure: a draw period followed by repayment.
This program asks for more up front than many owners expect. At least 80% of the line is drawn at closing, and that closing draw is never less than $50,000. On the smallest lines, that means the whole line is drawn at closing. Later draws are at least $5,000 each. This is a poor fit for an investor who wants a large standby line mostly left unused.
That is why the maximum line and a sensible draw are different questions. Because the stress test runs on the full limit while most of the line is drawn on day one, borrowing the maximum is rarely the same as borrowing wisely. Size the line to a plan, such as a rehab budget or the down payment on the next rental. The CFPB’s HELOC booklet shows the underlying logic: a credit limit is set as a percentage of appraised value minus the mortgage debt you already carry.
Key Terms Defined
- DSCR: The debt service coverage ratio, which here is gross monthly rent divided by the qualifying payment on the line.
- HELOC: A revolving line of credit secured by the property, drawn in pieces rather than paid out as one lump sum.
- CLTV: Combined loan-to-value, meaning the first mortgage balance plus the full new line, divided by the property’s value.
- Draw period: The stretch when you can borrow from the line, which on this program is 5 years of interest-only payments on the drawn balance.
- Seasoning: The holding or waiting time a rental must satisfy before a lender will place a line on it.
When Is Another Tool the Better Fit?
A DSCR HELOC suits an owner who likes the existing first mortgage and wants equity without touching it. Other tools fit different goals, and the right one depends on the investor and the property.
| Factor | DSCR HELOC | DSCR cash-out refinance | Personal-income HELOC |
|---|---|---|---|
| Existing first mortgage | Stays in place | Replaced | Stays in place |
| Qualified on | Rental income | Rental income | Personal income and DTI |
| Funds | Revolving line | One lump sum | Revolving line |
The personal-income column describes how an investment-property HELOC from a bank or credit union is typically underwritten. A DSCR cash-out refinance is a new first lien on the rental. It reprices the whole balance, which matters if your current first mortgage is one you would rather keep. It can also reach larger sums than a second-lien line capped at 70% CLTV. Investors who want the highest possible leverage should compare it before committing.
A DSCR HELOC cannot be written together with a purchase. It is never a third lien, and it is never a line on your own home or a second home. Self-employed investors and larger portfolio owners often prefer the rent-based test, since personal tax returns may not reflect the income they actually earn. LLC-held rentals need extra care, and Lendmire’s piece on HELOC rules for LLC-titled borrowers covers title and signing details. The complete DSCR loans guide puts the line next to the other rent-qualified products.
This program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee: Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington. 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.
Frequently Asked Questions
How much can I borrow if I still owe money on the rental?
Take 70% of the property’s value, subtract the first mortgage balance, and the remainder is the most a second-lien line can reach, up to $500,000 and subject to a 720 or better score. A first mortgage near or above that ceiling leaves little or no room. A declining-market flag lowers the ceiling by 5 points. The lender’s valuation and underwriting set the final figure.
Can my LLC hold title on a DSCR HELOC?
Yes, on this program an LLC can hold title to the investment property, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment along with the security instrument. The property must be a non-owner-occupied rental, since the line is never offered on an owner-occupied home.
How soon after buying a rental can I open a line?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date). Both have to be satisfied, so a recent purchase generally waits before it is eligible.
Does a higher rent coverage ratio raise my borrowing limit?
Not by itself. The 1.10x minimum is a threshold the rent has to clear, while the leverage ceilings come from the credit tier, the lien position and the line size. Stronger rent can help the file pass, but it does not move you into a higher leverage tier. Credit, equity and the valuation do that work.
Do I need a lease, and what if a unit is empty?
A lease in place is required. On a two-to-four-unit property, at most one unit may be vacant. The rent used for lender review is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. Properties with a pending listing in the prior 2 months fall outside the program.
