The Quick Read: It depends on your equity, because the line is sized by combined loan-to-value, and on a rental with a first mortgage, lines typically run up to 70% combined leverage at a 720 score, from $50,000 to $500,000, subject to underwriting, so the equity left after your first mortgage is usually the tighter limit.
- A second-lien line sits behind the first mortgage you keep. A first-lien line sits on a rental with no mortgage.
- The rent qualifies the line, not your personal income, subject to lender guidelines.
- The line funds the down payment and rehab. A DSCR cash-out refinance on the finished property then repays it.
- At least 80% of the line is drawn at closing, so size it to the cash you actually need.
Key Terms Defined
BRRRR: Buy, rehab, rent, refinance, repeat. You buy a property that needs work, fix it, lease it, refinance to pull your cash back out, and use that cash on the next one.
DSCR (debt service coverage ratio): The property’s gross monthly rent divided by its qualifying monthly payment. A result above 1.00x means the rent covers the payment.
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value. On a rental with no mortgage, the same math is plain LTV.
Draw period: The stretch when you can borrow from the line and pay interest only on what you have drawn. Repayment follows.
ARV (after-repair value): What the property is worth once the rehab is done.
Seasoning: The waiting period a lender wants after you buy or refinance a property before it will lend against it again.
What Is a DSCR HELOC, and Why Would a BRRRR Investor Want One?
A DSCR HELOC is a home equity line of credit on a non-owner-occupied one-to-four-unit rental. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. You get no tax returns, W-2s or personal income calculation. The line can sit as a standalone second lien behind a first mortgage you keep. It can also sit as a standalone first lien on a rental with no mortgage.
That is different from a standard HELOC, which is built around your credit, income and debt-to-income ratio. A line qualified on the rent opens another door.
BRRRR has one weak point. You need cash for the down payment and rehab before the refinance hands your capital back. Savings, hard money or a line against another property can cover that gap. A DSCR HELOC is another choice, and it works well when you already own a rental with real equity.
Think of the line as bridge money, not the exit. The exit is the refinance on the finished property. If you want the full picture of how rent-qualified loans work, Lendmire’s complete DSCR loans guide covers it.
How Much Can You Borrow?
Your maximum line is the property’s value times the maximum combined leverage, minus what you already owe. Opendoor’s HELOC explainer describes the same sizing logic for home equity lines in general. The program numbers below set the leverage ceiling.
Across the select programs Lendmire places files with, the tiers look like this. These are ceilings, subject to underwriting, not offers.
| Factor | Second lien | First lien (no mortgage) |
|---|---|---|
| Max leverage | 70% CLTV | 75% LTV at 740+; 70% at 700-739 |
| Credit floor | 720 | 700 |
| Line size | $50,000 to $500,000 | Up to $1,000,000 |
| Lines over $500,000 | Not available | 65% LTV at 720+ |
Two details matter here. First, a borrower who keeps a first mortgage can only take a second lien, and that tier starts at 720. A first lien exists only on a rental with no mortgage. Second, a declining-market flag can lower the ceiling by 5 points.
What this looks like in percentages
Say you own a rental with a first mortgage equal to 50% of its value. At a 70% CLTV ceiling, the line can use up to 20 points of that value. The line cannot take you above 70% combined.
Now say the first mortgage is only 30% of value. Forty points of room exist on paper. The $500,000 cap now becomes the limit if the property is valuable enough.
That is why equity, not the dollar cap, is usually the real constraint. A rental with a heavy first mortgage produces a small line, or none. A free-and-clear rental can produce a large one.
On the smallest lines, the $50,000 minimum closing draw can mean the whole line is drawn at closing. Any later draws are at least $5,000 each.
How the Rent Test Sizes the Line
The minimum DSCR is 1.10x. That is gross monthly rent divided by the qualifying payment. The qualifying payment is a fully amortizing principal-and-interest payment on the entire credit limit at a stress rate. Taxes and insurance are not part of it. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
The “entire credit limit” part is the gap many investors miss. The test counts the full line, not just the amount you plan to draw. A larger line therefore needs more rent behind it. If rent is thin, the coverage test can cap your line before the leverage tier does.
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 may have at most one vacant unit. A rental that is empty and waiting for a tenant does not fit this lane.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in the coverage calculation. The lender’s own calculation governs, and the numbers here are illustrative.
Where Does the Line Fit in a BRRRR Cycle?
The line fits at the front of the cycle, on a different property than the one you are buying. Here is the sequence.
1. Open the line on a rental you already own. It is never closed together with a purchase. It is also never a line on your own home or a second home.
2. Check 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).
3. Draw for the down payment and rehab. Your purchase loan is typically a DSCR purchase loan. That lender decides whether it accepts borrowed funds, so ask before you commit. Many DSCR purchase programs also want some cash in your own seasoned accounts. They generally treat an undrawn line as borrowing capacity, not reserves.
4. Rehab and lease the property. The refinance needs a lease in place.
5. Refinance with a DSCR cash-out loan. On a standard rental, the cash-out ceiling typically sits near 75% LTV in the programs Lendmire places with. Short-term-rental collateral typically tops out at 70%. Those caps belong to the cash-out refinance, not to the line.
6. Pay the line down and repeat. Proceeds must cover the first lien and the rehab cost. If they do not, the line stays partly drawn.
Why the line can fit the cycle better than short-term loans
A short-term loan has a fixed end date. If the property has not seasoned or the refinance slips, you scramble. A line has a 5-year interest-only draw period on the drawn balance. After that comes a 25-year fully amortizing repayment period, with a 30-year maturity. The rate is variable.
Bankrate explains the basic shape of a HELOC draw period and what happens when it ends. Experian describes it the same way, as a borrowing window followed by repayment. The terms above are this program’s own. Breathing room is the real benefit, not a promise about timing.
How Do You Size the Draw Backward From the Refinance?
Start with the exit, not the line. Work backward from the after-repair value.
Take your all-in cost: purchase price, rehab and carry. Express it as a percentage of ARV. Then compare that to the refinance ceiling of about 75% on a standard rental, subject to underwriting and appraisal.
- All-in at 70% of ARV: The refinance should repay the line and return some capital, with a cushion.
- All-in at 75% of ARV: The refinance only just covers the all-in cost, with no cushion. There is no room for a low appraisal.
- All-in at 85% of ARV: The refinance ceiling falls about 10 points of value short of the all-in cost, so you would have to cover that gap yourself and the line would not be fully repaid.
The line has to be repaid in full by the refinance proceeds, so it is only safe when the all-in cost fits under the refinance ceiling. Run that test before you draw.
Then check the rent test on the finished property. A rehab that lifts the appraised value but leaves rent flat can still fail on coverage.
Open the line at the size your deal requires, not the maximum available.
What Are the Edge Cases?
Your LLC. Vesting in the owner’s LLC is allowed on investment property, 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 valuation path. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted. A recently rehabbed rental may not show its new value in an automated valuation, so an appraisal can be the better path.
Ineligible property. Rural-designated property, row homes, condotels, leaseholds, mixed-use property and rentals listed for sale in the prior two months fall outside this lane. So do properties with a solar lien. Single-family, PUD, townhome, two-to-four-unit and condominium properties are eligible, subject to the leverage tiers above.
Credit history. The program wants no 30-day mortgage late in the last 12 months. It also wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
Who qualifies. U.S. citizens, permanent residents and non-permanent residents with a Social Security number can use the program. Foreign nationals and ITIN borrowers are not eligible.
Exposure limits. A borrower can hold at most 5 loans or $2,500,000 with the program. If you run a larger portfolio, count your existing loans before you plan the next line.
Where it is offered. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Availability varies by state, and Lendmire arranges it as a broker through a wholesale lender.
Where Do Investors Get Burned?
Three risks matter most.
A low appraisal on the exit. The refinance sizes on the appraised value. If it comes in under your plan, the proceeds may not clear the line. Leave a margin.
Stacked leverage. The first mortgage plus the line both count against the 70% CLTV ceiling on the source property. If you borrow to the limit there, you have no room for a second line on the same rental. Plan before you draw.
Carrying cost. The line has a variable rate and interest on at least 80% of the line from the start. That payment comes out of your cash even if the exit lender’s coverage test only looks at the new loan. It is real money while the rehab drags on.
One more point on sequencing. After the refinance, the finished property is a rental that was just refinanced, so it cannot back a new line until the seasoning rule above is met. Plan the next deal’s cash around a different property.
When Should You Skip the Line?
Skip it when your source rental has thin equity. After the first mortgage, the room may be too small to matter. Skip it when the rehab margin is thin, because a tight exit leaves no space for surprises.
Consider a DSCR cash-out refinance on the source rental instead if you want a larger lump sum than a line allows. It replaces your existing loan. The line sits beside it. Each fits a different goal.
A short pre-draw checklist helps:
- Confirm the source rental clears the seasoning rule and has a lease in place.
- Confirm your credit tier meets the lien position you need.
- Estimate all-in cost as a percentage of ARV.
- Ask the purchase lender whether it accepts borrowed funds.
- Check that rent covers 1.10x on the full line.
Frequently Asked Questions
Is there really a DSCR HELOC, or is that just a nickname?
It is a real structure in the select programs Lendmire places files with. It is a home equity line on a non-owner-occupied rental, qualified on the rental’s income rather than your personal income. A standard HELOC is built around your own credit and income instead. Qualification is subject to lender guidelines.
Can I open the line on the property I am buying?
No. The line is never closed with a purchase, so it cannot sit on a property you are still buying. It sits on a rental you already own. That is why equity in an existing rental is the starting point for this strategy.
How long must I own a rental before it can back the line?
A rental bought or refinanced in the last 6 months is off the table, counted from its last note date to the new note date, and you must also have held title for 6 months, counted from settlement date to note date. A property that fails either test is not a candidate.
Does a bigger line mean a better BRRRR plan?
No. At least 80% of the line is drawn at closing, so a larger line means more interest-bearing debt from the start. The rent test also counts the entire credit limit. Size the line to your deal, then test the exit refinance.
Can a 700 credit score get me a second-lien line?
Not on a second lien. That tier starts at 720. A 700 score fits a first-lien line, but only on a rental with no mortgage. If you keep a first mortgage, the second-lien floor applies. Confirm tiers with the lender, since every file is underwritten individually. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
