The Quick Read: Not as one pooled number, because each rental gets its own line, sized by that property’s value, the liens already on it, a combined-leverage ceiling and a rent-coverage test. Your total is the sum of what each property supports on its own, and equity in one rental never adds room to another.
- A second-lien line reaches 70% combined loan-to-value (CLTV) at a 720 score or better, on lines from $50,000 to $500,000, through select programs.
- A first-lien line on a rental with no mortgage reaches 75% loan-to-value (LTV) at 740 or better, and runs to $1,000,000 at a lower ceiling.
- Rent must cover a stress payment on the entire credit limit at 1.10x or better, drawn or not.
- Each program caps a borrower at 5 loans or $2,500,000 in total exposure.
- All figures are subject to underwriting and lender guidelines.
Why Is the Limit Set Property by Property?
A DSCR HELOC is secured by one rental, so its size comes from that rental alone. The CFPB’s HELOC booklet describes the basic mechanism: the lender applies a percentage to the appraised value, then subtracts the balance already owed. That booklet is old, so it is useful for the mechanism only, not for any percentage.
The formula for a rental is value times the allowed leverage, minus every lien already on the property. A dollar cap and a coverage test then apply to the result. Run it for each rental and add the answers. That sum is your portfolio number.
Two things follow:
- Strong equity in rental A does not help rental B.
- A rental bought recently with a thin down payment may start above the ceiling and support no line at all.
The CFPB’s HELOC explainer describes a HELOC as an open-end line you can borrow against repeatedly, secured by the property’s equity. On a rental that equity belongs to one building.
What Does a DSCR HELOC Look Like in Practice?
It is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never closed with a purchase and never a third lien. It is never written on your own home or a second home.
The rental’s income qualifies the line. Rent must cover the qualifying payment at 1.10x or better. That payment is a fully amortizing payment on the whole credit limit at the start rate plus 2 percentage points, so it is a stress test. Taxes and insurance are not part of it. Whether the first-mortgage payment joins the calculation on a second lien is not published, so confirm on the file how the lender treats it.
Rent is the lesser of the appraiser’s Form 1007 market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required. A two-to-four-unit building may have at most one vacant unit.
The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That means no traditional personal-income documentation, W-2s or personal income calculation. The credit report, lease, rent evidence and valuation are all documented. Vesting in your LLC is allowed on investment property, subject to program terms, with the members signing as guarantors.
What Leverage and Line Size Apply?
Leverage depends on lien position and score, and the two positions use different labels. On a second lien the figure is CLTV, meaning the first-mortgage balance plus the new line, divided by value.
| Lien position | Credit score | Ceiling | Line size |
|---|---|---|---|
| Second lien, investment rental | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien, no mortgage | 740 or better | 75% LTV | up to $500,000 |
| First lien, no mortgage | 700 to 739 | 70% LTV | up to $500,000 |
| First lien, no mortgage | 720 or better | 65% LTV | over $500,000 to $1,000,000 |
Below 720 there is no second-lien tier. A borrower who keeps a first mortgage can only take a second lien. A first lien exists only on a rental with no mortgage.
A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower. All of this is subject to underwriting.
How Do You Calculate the Portfolio Total?
Work one property at a time, in this order:
1. Take the value the valuation supports, not the price you hope for. 2. Multiply by the CLTV or LTV ceiling for that lien position and score. 3. Subtract the first-mortgage balance, if any. 4. Check the result against the line-size range and the 5-loan or $2,500,000 exposure limit. 5. Run the coverage test on the whole limit at the stress payment. 6. Keep the lowest answer. That is the line for that rental.
Then add the lines across rentals. Picture an investor with five rentals. Two have heavy mortgages and sit near the ceiling, so they support no line. One has no mortgage and qualifies for a first lien. Two have moderate balances and support second liens. The portfolio total is three lines, not five, and each was sized on its own.
Equity is rarely the only limit. Four things can bind, and the lowest one wins on each property:
| Constraint | What it limits | Where it bites |
|---|---|---|
| Equity after liens | Line room | Recently bought rentals |
| Rent coverage | Line size | Large lines on modest rent |
| Dollar cap | Line size | High-value, low-balance rentals |
| Exposure limit | Number of lines | Investors with many properties |
Why Does the Full Limit Drive Coverage?
The coverage test runs on the entire credit limit, not on what you draw. A bigger line means a bigger stress payment, so it lowers the ratio. A rental with modest rent may clear 1.10x on a smaller line and fail on the maximum.
The practical move is to size the line to the rent, not to the equity. Ask for what the coverage test supports. Pulling equity from a rental whose rent barely clears at the full limit is a poor use of the structure.
Draw rules matter too. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines the whole line is drawn at closing. Later draws are at least $5,000 each. The draw period is 5 years interest-only on the drawn balance, then a 25-year fully amortizing repayment period, with a 30-year maturity. The rate is variable, and the lender’s HELOC disclosures carry the pricing terms.
Stacked lines on several rentals each carry a variable-rate payment. When rates move, every line moves at once. Plan for the combined carry, not each line alone. A lender can also freeze or reduce a line if value falls, which the CFPB notes. A rental line is not guaranteed liquidity.
What Does the File Need on Each Rental?
Every rental is its own file. Documents typically include the first-mortgage statement, insurance declaration, vesting deed, current lease and rent evidence.
- Valuation: lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal. Appraisal waivers are not accepted. Investors commonly face more than one appraisal across a portfolio, a point NerdWallet’s investment-property explainer also raises.
- Title: a full title policy on a first lien and on second liens above $400,000. Smaller second liens take an owner-and-encumbrance report.
- Insurance: hazard coverage covers both liens, with flood coverage where required.
- Credit: 720 minimum on a second lien and 700 on a first lien, with no 30-day late on the mortgage in the last 12 months. Bankruptcy, foreclosure, short sale or deed-in-lieu needs 48 months of distance.
- Reserves and cash to close: none required.
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). A property listed for sale in the prior 2 months is out.
Which Rentals Fall Outside the Program?
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 not eligible on this lane. A property with a solar lien is also out.
Eligible types include single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums. Lots up to 10 acres qualify. A fourplex counts as one property with several rents, so it is one loan against the exposure limit, not four.
Borrowers must be US citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Separate Lines, Cash-Out or a Blanket Loan?
A line is one tool among three, and the right one depends on the property.
| Structure | First mortgage | Coverage judged on | Best fit |
|---|---|---|---|
| DSCR HELOC per rental | Stays in place | Each rental alone | Cheap first mortgage worth keeping |
| DSCR cash-out refinance | Replaced | Each rental alone | Rental with thin or no first-lien advantage |
| Blanket or portfolio loan | Often replaced | Pooled across properties | One note for many rentals |
A line leaves the first mortgage untouched. Per the CFPB, a HELOC is a second mortgage when a first one exists. A refinance replaces it. A blanket loan pools coverage, so strong properties can mask weak ones, and it needs release clauses to sell one property. Lendmire’s piece How Much a Portfolio DSCR Loan Lends Across Several Rentals covers that structure.
Many bank products lean on personal income and debt-to-income. A DSCR line does not.
Which Rental Do You Borrow Against First?
Start with the property that clears coverage with the most room and carries the lowest combined leverage. That file has the fewest ways to fail. It also keeps your exposure count low.
Sequence matters for one more reason. The line must exist before you go under contract on the next property, and a purchase cannot be closed together with a line. Open the line first, then buy.
Watch the exposure count. With a limit of 5 loans or $2,500,000 per borrower with the program, an investor with many rentals runs out of room before running out of equity. Each additional line also lowers the count left for the next.
Mixed title works in practice. Personally titled rentals and LLC rentals each file separately. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line need not match the borrowers on the first mortgage.
Key Terms Defined
- CLTV: the first-mortgage balance plus the new line, divided by the property’s value.
- Draw period: the 5-year interest-only window when you can borrow against the line.
- DSCR: gross monthly rent divided by the qualifying payment.
- Stress payment: a fully amortizing payment on the full limit at the start rate plus 2 percentage points.
- Blanket loan: one note secured by several properties.
Frequently Asked Questions
Can one DSCR HELOC cover several rentals at once?
No. Each line is secured by one property and sized on that property alone. Several rentals mean several separate lines, each with its own valuation, lease, title review and coverage test, subject to underwriting.
How many DSCR HELOCs can one borrower hold?
The program limits a borrower to 5 loans or $2,500,000 in total exposure. A multi-unit building counts as one loan. Which limit hits first depends on line sizes.
Does an LLC on title block the line?
Not on this program. Vesting in your LLC is allowed on investment property, subject to program terms, and the members sign as guarantors. Many bank lines exclude LLC title, so confirm before you apply.
How long must I own a rental before borrowing against 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).
Does a higher credit score raise my leverage on a second lien?
On a second lien, 720 or better qualifies for the 70% CLTV ceiling, and there is no tier below 720. On a first lien, scores of 740 or better reach 75% LTV and 700 to 739 reach 70% LTV, subject to underwriting. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
