The Quick Read: Plan the whole BRRRR backward from the date your HELOC stops being interest-only. That switch date, not the rehab schedule, sets how long you can carry the balance cheaply, so the refinance must retire the line before it arrives or rent must absorb the higher payment.
- A DSCR loan is an investor loan sized on whether the rent covers the property’s monthly payment. It is the usual exit for a BRRRR, and it must pay off the HELOC, any first lien, and the rehab spend in one transaction.
- During the draw period, most lines charge interest only. When repayment starts, Experian reports the payment can more than double.
- On an investment property, a HELOC through Lendmire’s wholesale network caps at 70% CLTV and $500,000, with a 5-year draw and a 25-year repayment. Pricing floats the whole time.
- Clearing a coverage ratio of 1.00 on the exit loan is not the same as positive cash flow. Repairs, vacancy, management, and capital spending sit outside the ratio.
A brokered HELOC is bridge money. Treat the interest-only window as borrowed time, not as free cash flow.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Key Terms Defined
Draw period is the stretch when you can borrow from the line and, on most lines, pay only interest on what you have drawn.
Repayment period is the stretch after the draw ends. You can no longer borrow, and the balance is paid down over a set term.
Amortizing payment is a payment that covers interest and principal, so the balance shrinks to zero by the end of the term.
Balloon payment is a structure where the full balance comes due when the draw period ends.
CLTV (combined loan-to-value) is every loan on the property added together, divided by its value.
PITIA is principal, interest, taxes, insurance, and association dues. DSCR compares rent to this figure.
Seasoning is the waiting period a lender wants after you buy before it will refinance on a new value. Most files in the network expect about six months from the recorded deed.
What Does the Repayment Switch Actually Do?
The switch ends your ability to borrow and starts a fully amortizing payment on whatever balance is still outstanding. The cost of carrying the line rises on the same balance, at the moment a delayed refinance is hardest to absorb.
Across the market, Experian describes a typical draw period of five to 10 years, followed by about 20 years of repayment. It also notes that most lines carry variable pricing. On the investment line in Lendmire’s network, the structure is a 5-year interest-only draw followed by a 25-year amortizing repayment. Pricing floats through both phases and never converts to a fixed figure.
NerdWallet makes the same point from the borrower side: because most lines require only interest during the draw, repayment shock arrives when that period ends. Shock is the right word. Nothing about the property changed, yet the monthly carry on the same debt jumped.
Two details make it worse for investors. First, the clock starts when the line closes, not when you buy the property. A line opened years before a deal may be close to its switch date on day one of the rehab. Second, on the structures placed through the network, at least 75% of the line is drawn at closing. Interest begins on most of the line immediately, so model the carry on the funded balance, not on a draw-as-needed assumption.
How Does the Line Map to Each BRRRR Stage?
The line pays for the buy, the rehab, and the hold, and it must be paid off at the refinance. Each stage carries interest-only cost, so the cash-flow model needs a carry line for every month until the payoff.
| Stage | What the line funds | Payment during draw | What to watch |
|---|---|---|---|
| Buy | Down payment, closing costs | Interest only | Most of the line is drawn at closing |
| Rehab | Contractor invoices | Interest only | Overruns raise the balance |
| Rent | Holding costs, vacancy | Interest only | Slow lease-up extends the carry |
| Refinance | Nothing new; payoff | Ends at payoff | The exit must retire the whole line |
| Repeat | Restored line | Resumes | Only if the line is still open and paid down |
Size the line to the need. Unused cash you drew at closing still costs interest, so borrowing the maximum “just in case” is a cash-flow decision, not a free cushion.
How Do You Calendar the Switch Before You Buy?
Find three dates in the line agreement: when the draw ends, how long repayment runs, and whether a balloon applies. Then lay them next to your own timeline of purchase, rehab, lease-up, seasoning, and refinance. If the refinance cannot realistically finish with real buffer before the draw ends, the deal needs a different funding source.
Run it as five steps:
1. Write down the draw end date and the repayment term from the agreement.
2. Add the rehab schedule, then lease-up, then the seasoning window of about six months on most cash-out files.
3. Mark the earliest date the refinance could realistically fund the payoff.
4. Subtract that date from the draw end date. That gap is your buffer.
5. Stress the buffer. Add rehab overruns and a slow lease-up, then see whether the gap survives.
This is also where qualification matters. Investment HELOCs in the network qualify on a debt-to-income basis of up to 50%, calculated on the interest-only payment at the maximum draw. Underwriting does not test the repayment payment. You have to.
How Does the DSCR Exit Treat the Payoff?
The exit lender sizes the new loan on the new appraisal and on whether rent covers the new payment. It does not size on your projected after-repair value or on your personal income. The new loan has to pay off the first lien, the HELOC, and the rehab spend at once, and the larger new payment still has to be covered by rent.
Across most programs we place files with, cash-out refinances top out around 75% LTV on a standard rental, with about six months of seasoning as the common expectation. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. Reserves vary by lender, leverage, and loan size, and commonly run around six months of PITIA. A coverage ratio of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. The complete DSCR loans guide walks through those tiers in detail. A loan to an LLC is possible subject to lender program eligibility.
A Worked Cash-Flow Test (Modeled, Not Sourced)
These inputs are modeled assumptions, and they use percentages and ratios only.
Say your line balance equals 70% of projected value. A 75% cash-out refinance leaves about 5% of value in cash before costs. The appraisal can come in about 7% light before the maximum new loan drops below the line balance. After that, the refinance does not retire the line. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
That margin is thin, and closing costs and the seasoning window can use all of it. This is why strong files treat the exit appraisal, not the projection, as the number that matters.
Now test cash flow in three columns:
- Draw phase: the drawn balance times the line’s interest cost, spread over twelve months, subtracted from rental income after PITIA.
- Repayment phase: a standard amortizing payment on the same balance over the repayment term, subtracted the same way.
- Stress case: both of the above at stabilized rent and again at rent 10% lower.
Then add the lines DSCR ignores: repairs, vacancy, management, utilities, and a capital reserve. If the repayment-phase column goes negative in the stress case, you have found the deal’s real exit deadline.
Where Does the General Rule Break?
The general rule is that a line moves from interest-only to amortizing and a refinance retires it. These edge cases bend that rule.
Balloon lines. Some agreements require the full balance at draw end. The CFPB warns that the whole amount may be due when repayment begins. With a balloon, the refinance is mandatory, not optional.
Minimums that include principal. Some lines require a payment with a principal portion even during the draw. The switch is then smaller but not zero.
Interest-only is not fixed cost. Because pricing floats, the payment can change even when you draw nothing more. The Federal Reserve’s interagency guidance describes the end-of-draw choice as a balloon due immediately or higher payments over the remaining term, and calls the result payment shock.
Renewal. Some lenders will renew a line at draw end. That is the lender’s call, not your right, so never build a plan on it.
Which property secures the line. A line on your primary home puts that home behind the deal. On a primary residence, the network’s ceiling reaches 90% CLTV, but only at a 720 or better credit profile. On an investment property, the ceiling is 70% CLTV, with a $500,000 maximum line and a 700 minimum score. Because of that cap, investment lines are valued by automated valuation and commonly close without a traditional appraisal. LLCs, corporations, and land trusts cannot hold title on these lines. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead. Manufactured homes, log homes, and barndominiums are not offered on either product.
Delayed financing. This is a waiting-period exception borrowed from conventional lending. Across our network, a HELOC on another property is often not treated as cash, so expect the line to be paid off at the refinance. A property bought with hard money generally does not fit delayed financing either, and a hard-money lien can also block a HELOC that wants first position.
Stacking deals. One line means one switch date. A purchase in year four of a 5-year draw leaves roughly twelve months for rehab, lease-up, seasoning, and refinance. A borrower is also limited to three lines, and an owner with more than 15 financed properties is not eligible.
What If the Refinance Runs Late?
Treat a late refinance as a planned scenario, not a surprise. Each delay has a trigger, an impact, and a response, and you should write the response down before you close on the line.
| Scenario | Trigger | Impact | Response |
|---|---|---|---|
| Rehab overrun | Costs rise, balance grows | Larger payoff, less buffer | Cap the line draw; hold reserves |
| Light appraisal | Value below projection | Max loan under the balance | Pay down principal or hold |
| Seasoning not cleared | Refinance too early | Sizing falls to cost basis | Wait out the window |
| Rent short | Lease-up slower | Coverage below target | Extend lease-up; test sub-1.00 path |
What Are the Fallback Exits?
Fallback exits trade cash, time, and leverage against each other. Choose the least costly one before you need it.
| Option | Trade-off |
|---|---|
| Pay down principal | Uses reserves; shrinks the payoff gap |
| Smaller payoff-only refinance | Retires the line; no cash returns |
| Ask for renewal | Lender discretion; no guarantee |
| Hold and reappraise | Carries the higher payment longer |
| Sub-1.00 select-lender path | Leverage and terms adjust |
| Sell | Ends the cycle; transaction costs apply |
Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Eligibility depends on the borrower, the property, and full file review.
A Pre-Commitment Checklist
Answer these before you sign for the line.
- When does the draw end, and does a balloon apply?
- Does the minimum payment include any principal?
- What is the full cost of the funded balance from closing, given the line draws most of its limit up front?
- Does the repayment payment still clear in a stress case at 10% lower rent?
- Is the property in your name, or does an LLC hold it?
- What does the exit lender need: appraisal, lease or rent schedule, and entity papers?
- Do the reserves cover both the carry and the exit lender’s reserve requirement?
- Which of the fallback exits can you actually execute? Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
When Not to Do This
Skip an HELOC-funded BRRRR when the deal only works if everything goes right. Financing most of a buy-and-hold deal on a line usually leaves thin cash flow. If the repayment payment cannot be carried at lower rent, the plan depends on a refinance happening on schedule, and refinances do not always happen on schedule. A primary-home lien also raises the stakes well past the rental itself.
Next Step
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. HELOC placements are available in 16 full-service states, narrower than the DSCR footprint of 41 markets including Washington, D.C. Programs change, every file is reviewed individually, and none of this is a commitment to lend.
Frequently Asked Questions
Can I use a HELOC to fund a BRRRR?
Yes, many investors do, usually for the down payment, the rehab, or holding costs. The line is bridge capital, so you need a plan to refinance out of it. Plan the DSCR exit before the purchase, not after the rehab, and confirm how the lender treats the borrowed funds.
What happens when the draw period ends?
You can no longer borrow, and the repayment period starts. Depending on the agreement, the balance is either due in full or amortized over the remaining term at a higher payment. On the investment line in Lendmire’s network, the draw is five years, followed by 25 years of repayment, with floating pricing throughout.
Do I have to refinance out of the line?
Not always, but you need a plan for the balance. A balloon agreement makes a refinance mandatory. On an amortizing agreement you could keep the line, but that means carrying a higher payment, so test rent at a lower level first.
What if my line’s cost changes during the draw?
The payment moves even if you borrow nothing more. Pricing on these lines floats through both the draw and repayment periods. Build a stress case with a higher cost of borrowing into the cash-flow test, and plan an early payoff.
Is HELOC interest deductible?
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
