The Quick Read: It depends on lien position and credit, but on a rental with a first mortgage, a second-lien line reaches 70% combined loan-to-value at the top credit tier, with lines up to $500,000 once the full appraisal sets the value. A first lien on a rental with no mortgage can reach 75% at the top credit tier on lines up to $500,000, or 65% on first-lien lines above $500,000, subject to underwriting. Lines above $400,000 require a full interior appraisal, so the appraised value becomes the number everything else is built on.
- A second lien behind your first mortgage reaches 70% CLTV at a 720 or better score, on lines up to $500,000.
- A first lien on a rental with no mortgage reaches 75% LTV at 740 or better and 70% at 700 to 739, on lines to $500,000.
- First-lien lines above $500,000 run to $1,000,000 at a 65% LTV ceiling and a 720 or better score.
- Rent coverage must reach 1.10x against a stress payment on the entire line, not just the drawn balance.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a revolving line secured by a 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 the line. The program calculates no personal income, and it asks for no traditional personal-income documentation, W-2s or pay stubs. The owner’s LLC can stay on title, subject to underwriting and the title and guarantor paperwork.
The label is loose in the market. Some lenders use it for a cash-out refinance, some for a closed-end second. Here it means a true open line on a one-to-four-unit non-owner-occupied rental, placed through select lenders in Lendmire’s wholesale network. It is never a line on your own home, and it is never closed together with a purchase.
Two features matter for sizing. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. The draw period is 5 years interest-only on the drawn balance, followed by a 25-year repayment period and a 30-year maturity. The rate is variable, and the pricing terms come with the lender’s disclosures.
How the Maximum Line Is Calculated
The line is property value times the maximum combined leverage, minus every lien already on the property, then limited by the program’s maximum line size. The smaller result wins. This is the standard sizing method for home equity lines, and the CFPB’s HELOC booklet describes it as a percentage of appraised value less the existing mortgage balance.
Work it in this order:
1. Take the appraised value from the full appraisal. 2. Multiply by the leverage cap for your lien position and credit tier. 3. Subtract the first mortgage balance if you are taking a second lien. 4. Compare the result to the line-size ceiling, which is $500,000 on a second lien. 5. Test rent coverage against a stress payment on the full limit.
Combined loan-to-value counts the first mortgage plus the whole new line, whether or not you draw all of it. That is why usable equity is always smaller than total equity. A rental with a first mortgage at 40% of value leaves 30 points of room under a 70% combined cap. A rental with a first mortgage at 60% leaves only 10 points.
Why a Full Appraisal Comes In Above $400,000
Lines up to $400,000 can run on an automated valuation with a property inspection report, or on a full interior appraisal if you prefer one. Above $400,000, the full interior appraisal is required. The appraiser uses Form 1004 for a single-family home, Form 1073 for a condominium, or Form 1025 for a two-to-four-unit property. Appraisal waivers are not accepted on this program.
The valuation path matters because it sets the ceiling. The appraisal also produces the market-rent schedule that feeds the coverage test. 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 in place is required, and a two-to-four-unit building can have at most one vacant unit.
Title scales with the line too. A full title policy applies on a first lien and on second liens above $400,000. Smaller second liens can use an owner-and-encumbrance report.
Automated models are weaker where comparable sales are thin or the property has unusual features, as Redfin’s explainer on automated valuation models notes. That is one reason larger lines get a person walking the property. An appraiser can also credit a recent rehab that a data model would miss, though the appraised value still depends on comparable sales and underwriter review.
Which Limit Controls at the High End?
At the high end, one of three limits binds first: the combined-leverage cap, the line-size ceiling, or the 1.10x coverage test. Checking only one of them is how investors overestimate the line.
| Situation | Likely binding limit |
|---|---|
| High value, small first mortgage, second lien | $500,000 line ceiling |
| Moderate value, large first mortgage | 70% CLTV cap |
| High value, strong equity, thin rent | 1.10x coverage on the full line |
| No mortgage, line above $500,000 | 65% LTV ceiling |
The coverage test is the one people miss. The qualifying payment is a fully amortizing payment on the entire credit limit at a stressed start rate, principal and interest only. Taxes and insurance are not part of it. A bigger line raises the stress payment in step, so rent that clears 1.10x on a $200,000-class line may fall short on a $500,000 one. Confirm on the file how the lender treats the first-mortgage payment in the coverage calculation on a second lien, because that treatment is not published as a single formula.
A property flagged as being in a declining market loses 5 points of ceiling. A second lien that would have reached 70% CLTV then reaches 65%. Philadelphia lines carry a ceiling 10 points lower.
First Lien vs. Second Lien Above $400,000
A second lien is the right structure when you want to keep the first mortgage. Credit must be 720 or better, the combined cap is 70%, and the line stops at $500,000. Nothing above 70% is available in the second-lien position, and no second-lien line runs above $500,000.
A first lien exists only on a rental with no mortgage. The top tier is 740 or better at 75% LTV. Scores of 700 to 739 get 70% LTV. Both tiers run to $500,000. Above $500,000, lines run to $1,000,000 at a 65% LTV ceiling and a 720 or better score. A borrower who keeps a first mortgage can only take a second lien, so the 720 floor applies. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Credit above the tier floor buys eligibility, not extra leverage on a second lien. A 740 score and a 720 score reach the same 70% CLTV there. Mortgage history also counts: no 30-day late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required.
If the Appraisal Comes In Low
A low appraisal shrinks the line in a straight calculation, and both leverage and coverage can move. Rerun the sizing with the new value. Multiply the new value by the cap, subtract the first mortgage, and compare to the ceiling. Then test the new market rent against the stress payment on the new limit.
Picture an owner who expected a $500,000 second lien on a rental with a first mortgage near 40% of value. If the appraisal lands 10% under the estimate, the first mortgage now takes up a larger share of the lower value, and the CLTV cap applies to a smaller number. The room left for the second lien shrinks on both counts, so the cap may now set the line size instead of the ceiling.
You have three practical moves:
- Ask for appraisal reconsideration with recent nearby sales and condition evidence.
- Take a smaller line that fits the new cap.
- Drop below $400,000 if the numbers support it, where an automated valuation with an inspection report is the other valuation path.
Value can also move after closing. The CFPB explains that a lender may stop further draws if the property’s value falls significantly. Draws are not guaranteed for the full term, so size the line for the money you need rather than the largest number on paper.
Is a Smaller Line Worth It to Avoid the Appraisal?
Sometimes. A line at or below $400,000 can use an automated valuation with an inspection report, and the full interior appraisal is optional. If the project only needs a mid-sized draw, the smaller line keeps the valuation path simpler and the stress payment lower, which helps coverage.
The trade-off is capacity. At least 80% of the line is drawn at closing, and lines start at $50,000, so a smaller line means a smaller pool for later draws. Size to the project. Do not size to avoid a document.
For a rehab, the full appraisal can be worth ordering even when it is optional. A model built on public records may not see the improvements. NerdWallet notes that rental lines draw from a smaller lender pool with stricter requirements and may involve more than one appraisal, so plan the valuation step with the lender up front.
Line vs. Cash-Out Refinance at High Values
| Factor | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place on a second lien | Replaced by the new loan |
| Reviewed on | Rent against a stress payment on the full line | Rent against the full payment |
| Draw structure | Revolving, 5-year interest-only draw | One lump sum |
| Size ceiling | $500,000 second lien | Set by the term-loan program |
If you need more than $500,000 and still carry a first mortgage, the line is not the tool. A cash-out refinance replaces the first lien and can be sized by a term-loan program.
What Keeps a File Out of the Program
Several limits sit outside the leverage math. 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).
Property type is the other gate. Eligible types include single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, mixed-use, and land contracts are outside it. So is a property listed for sale in the prior 2 months and a property with a solar lien.
Exposure is capped at 5 loans or $2,500,000 per borrower with the program. Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Across the wholesale network, the practical documents are the lease, the credit report, the first-mortgage statement, hazard insurance covering both liens, flood coverage where required, and the vesting evidence. LLC borrowers also supply entity documents and guarantor signatures, subject to lender program eligibility. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.

Frequently Asked Questions
Can I borrow more than $500,000 on a DSCR HELOC?
Only as a first lien on a rental with no mortgage. Those lines run above $500,000 up to $1,000,000 at a 65% LTV ceiling and a 720 or better score. A second lien behind your first mortgage stops at $500,000. All figures are subject to underwriting.
Does a higher credit score raise my second-lien limit?
No. A second lien reaches 70% CLTV at 720 or better, and nothing higher is offered in that position. Higher credit helps the file, but it does not move the cap. On a first lien, the score does change leverage: 740 or better reaches 75% LTV and 700 to 739 reaches 70%. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
How soon after I buy or refinance can I open a line?
Lenders generally want you to have held title for about 6 months of seasoning before a line can be opened. A recent purchase also has limited room, since a combined cap near 70% leaves little after acquisition leverage.
Will the rent I charge increase the size of the line?
Not directly. Rent has to clear 1.10x against the stress payment, but the line size is set by value, leverage and the ceiling. 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. Higher rent helps the coverage test only.
Is the program available everywhere?
The program is not offered in every state. It is available in Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington. Availability, leverage and valuation rules are subject to lender guidelines and individual file review.
