The Quick Read: It depends on the equity left after the first mortgage. Through select programs, a second-lien line on a rental reaches 70% combined loan-to-value at a 720 score or better, subject to underwriting. A first-lien line on a rental with no mortgage is a separate case, and it has its own loan-to-value tiers. The rent has to cover a stress payment on the whole line, not just the amount drawn. Lendmire, a mortgage broker, places these lines through a wholesale lender in its network.
- The formula: property value times the allowed leverage, minus every lien already on that property.
- Second lien (you keep a first mortgage): 70% combined loan-to-value at 720 or better, on lines from $50,000 to $500,000. No second-lien line goes above that ceiling.
- First lien (no mortgage on the rental): with no other lien, these limits are plain loan-to-value: 75% at 740 or better, 70% from 700 to 739, and 65% at 720 or better on lines above $500,000, up to $1,000,000.
- The coverage test: rent must cover the stress payment on the entire credit limit at 1.10x or better.
- The catch for scaling: each line is secured by one property, so equity in one rental never pools to support another.
What a DSCR HELOC Is and What It Isn’t
A DSCR HELOC is a revolving line secured by a one-to-four-unit rental you keep. It is written as a standalone second lien behind your existing first mortgage, or as a standalone first lien on a rental with no mortgage. The rent qualifies it. The file carries no tax returns, W-2s, pay stubs or personal income calculation, subject to lender guidelines.
That structure answers a problem investors run into often. NerdWallet notes that HELOCs on investment property are harder to get than lines on a primary home because lenders see higher default risk, and that not every lender offers them. It also points rental owners toward a DSCR second mortgage as a possible better fit. Across a wholesale network, few programs write this product, and each sets its own ceilings.
Three things this line is not. It is not closed together with a purchase. It is not a third lien. It is not a line on your own home or a second home.
Vesting in your LLC is allowed on 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 and the security instrument. The borrowers on the line don’t have to match the borrowers on the first mortgage. For the full picture of how rent-based lender review works, see Lendmire’s complete DSCR loans guide.
Key Terms Defined
Combined loan-to-value (CLTV): the first mortgage balance plus the new line, divided by the property’s value. Second-lien figures are written this way.
Loan-to-value (LTV): the line divided by value when no other mortgage exists. First-lien figures are written this way.
DSCR: the gross monthly rent divided by the qualifying payment. This program’s floor is 1.10x.
Stress payment: a fully amortizing payment on the entire credit limit, figured at the start rate plus 2 percentage points. It is a test, not what you actually pay.
Draw period: five years of interest-only payments on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity, at a variable rate.
Seasoning: the time since a rental was bought or refinanced, and the time you have held title.
How to Size the Line, Step by Step
Start with value, apply the leverage cap for your lien position, subtract what is already owed, then check the result against the line minimum and maximum. Rent coverage and credit can then lower the number further.
1. Establish value. 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.
2. Pick the lien position. If you keep a first mortgage, the line is a second lien with a 720 floor. If the rental has no mortgage, it is a first lien with a 700 floor.
3. Multiply value by the cap. That gives the total debt the property can carry.
4. Subtract existing liens. The line limit, not your drawn amount, is what counts toward combined leverage.
5. Apply the dollar limits. Lines start at $50,000, and the usual ceiling is $500,000.
6. Test the rent. Covered below.
A rental with a first mortgage
Say the first mortgage sits at 50% of value and your score is 720 or better. A 70% combined cap leaves room for a line of up to 20% of value. At a first mortgage of 60% of value, the room shrinks to 10%. At 65%, it is about 5%. At 70% or more, there is none.
The room also has to be large enough to clear the $50,000 minimum line. A modestly priced rental with a first mortgage near the cap may have room in percentage terms but not in dollars.
A rental with no mortgage
A paid-off rental opens a first lien. At 740 or better, the cap is 75% LTV. From 700 to 739, it is 70% LTV. The line stops at $500,000 at those tiers, so on a higher-value property the dollar cap binds before the percentage does. Above $500,000, lines run to $1,000,000, but the ceiling drops to 65% LTV at 720 or better.
A rental bought with a small down payment
A rental bought with a small down payment carries a first mortgage that already sits near the 70% combined cap. There is usually no second-lien room until paydown or appreciation creates it. The seasoning rule also applies. 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).
Two adjustments can shave the ceiling further. A declining-market flag on the property lowers it 5 points, and Philadelphia lines carry a ceiling 10 points lower.
What Else Limits Your Number
| Limiter | What it does |
|---|---|
| Equity | Value times the cap, minus liens |
| Lien position | Second: up to 70% CLTV. First: LTV tiers |
| Credit score | 720 for second lien; 700 for first |
| Rent coverage | 1.10x on the full limit |
| Line size | $50,000 minimum; $500,000 usual ceiling |
| Borrower exposure | 5 loans or $2,500,000 per borrower |
Credit also carries history rules. There can be no 30-day mortgage late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required. A higher score buys eligibility and, on a first lien, a higher tier. It does not buy leverage beyond the ceilings above.
The Rent Test Can Cap You Before Equity Does
Qualifying runs on the rental’s income. Rent is the lesser of the appraisal’s market rent (Form 1007) and the lease, unless three months of receipts support a lease above market. A lease in place is required. A two-to-four-unit property may have at most one vacant unit.
The payment that rent is measured against is principal and interest on the entire credit limit, at the stress rate. Taxes and insurance are not part of the qualifying payment. Because the whole limit is tested, a larger line raises the stress payment against the same rent. A property with healthy equity can therefore be limited by coverage rather than by leverage.
The practical read: if rent only just clears 1.10x at the line you want, expect to size down. Confirm on the file how the lender treats the first-mortgage payment on a second lien, because the lender’s own coverage calculation governs. Treat any arithmetic you run yourself as illustrative.
Can the Line Buy the Next Rental?
Yes, but indirectly. The line is never closed with a purchase, so it funds the next deal as cash you draw from a rental you already own. It works best as a down-payment and reserves tool, not as the full purchase price.
The sequence looks like this:
1. Confirm the line is possible on the rental you would borrow against: equity, seasoning, property type, credit and rent coverage.
2. Close the line. At least 80% of it is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, that means the whole line.
3. Hold the funds for the next acquisition. Later draws are at least $5,000 each.
4. Ask the purchase lender how it treats borrowed funds before you write an offer. Treatment varies by lender, and some require the money to sit in the account for a period.
5. Buy the new rental on its own financing.
After the five-year draw period, the loan becomes fully amortizing over 25 years. The CFPB’s explanation of a HELOC describes this same shape: draw first, then repayment. A variable rate means the payment can move after closing.
One more point for buyers of more rentals. Equity in one rental supports a line only on that rental. A portfolio of five properties produces five separate sizing exercises, not one pool. The program also stops at 5 loans or $2,500,000 per borrower.
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.
HELOC, Cash-Out Refinance, or Bank Line?
The right tool depends on whether the first mortgage is worth keeping and whether the investor’s personal income file helps or hurts.
| Factor | DSCR HELOC | DSCR cash-out refinance | Bank investment HELOC |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Stays in place |
| Reviewed on | Rent coverage | Rent coverage | Personal income and DTI |
| Leverage ceiling | Up to 70% CLTV (second lien) | Set by the cash-out program’s LTV rules | Set by each bank |
| Payment shape | Interest-only draw, variable | Single new loan | Varies by bank |
| Title | LLC allowed, subject to program terms | LLC common | Often personal title |
The cash-out and bank columns describe those products’ typical rules, not this program’s.
The HELOC makes more sense when the existing first mortgage has terms worth keeping, or when you want to leave that loan alone. A cash-out refinance can make more sense if the first mortgage has no such advantage, or if the extra leverage a cash-out program allows on a standard rental matters. A bank line may fit a salaried borrower with strong income and a long relationship, though the lender pool is small. Investors comparing providers can read Lendmire’s look at how providers of investment property HELOCs compare for investors buying more rentals.
Where the Plan Breaks
The most common breaking points are structural, and most are visible before you apply.
- Property 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 and mixed-use are outside this lane. So is a property listed for sale in the prior 2 months, or one with a solar lien.
- Eligible types. Single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots to 10 acres are eligible, with the leverage tiers above governing every type.
- Borrower type. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
- State. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, so confirm availability for the property’s state before you plan around it.
- Insurance. Hazard insurance must cover both liens, with flood coverage where required.
- Value. A weak valuation lowers value in the formula, which lowers the line.
A word on the alternative many investors reach for first: a line on the home they live in. The CFPB warns that you could lose your home if you cannot repay a home equity line. This program is never offered on an owner-occupied home. Using a rental’s own equity keeps that risk with the rental.
Size the Line to the Deal, Not to the Ceiling
The ceiling is the most the program allows, not what the plan needs. A smaller line leaves more cushion in both measures that matter: combined leverage and rent coverage on the stress payment.
The CFPB’s HELOC booklet explains that lenders set a credit limit by taking a percentage of the home’s value and subtracting the mortgage balance. The same logic applies here. A practical approach is to work backward from the cash the next acquisition needs, then confirm the rental can support that line with room to spare.
Keep the draw rule in mind. Because at least 80% of the line is drawn at closing, a line larger than the plan needs means paying interest on idle cash. Right-sizing therefore saves more than it would on a line you could leave undrawn.
Frequently Asked Questions
Does the HELOC payment count against the new rental’s coverage ratio?
The line is tested on its own rental’s rent, and the new purchase is tested on its own rent. What differs by lender is how the purchase lender treats the line’s payment and the borrowed funds. Ask the purchase lender before you write an offer, because treatment varies by program.
What credit score do I need?
A second lien needs a 720 score. A first lien on a rental with no mortgage needs 700. Mortgage history also matters: no 30-day late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. Lender guidelines govern.
Can my LLC hold title?
Yes, subject to program terms. Vesting in your LLC is allowed on investment property. The borrowers on the line don’t have to match the first mortgage borrowers.
How long do I have to own a rental before borrowing on it?
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). The next rental does not need to be seasoned, since the line is only secured by the property you already own.
How many properties or lines can one investor have?
The program allows at most 5 loans or $2,500,000 per borrower. Each line is secured by one rental, and the 5-loan and $2,500,000 limits count across the program. Once an investor nears either limit, a DSCR cash-out refinance or other financing becomes the more practical path.
Want to See How the Numbers Work on Your Rental?
If you are considering a home equity line on a rental property and want to see how the numbers work, Lendmire can help you compare DSCR HELOC options based on the property, the rent, the equity available, credit profile, combined leverage, and your goals. Programs change, and every file is underwritten individually by the lender; none of this is a commitment to lend. Whether a given rental’s equity stretches to the next acquisition comes down to one property at a time, because the line follows that property alone.
