The Quick Read: A HELOC is a revolving credit line secured by your home, and full repayment begins when the draw period ends, but interest-only payments usually start as soon as you borrow, and qualifying means passing credit, income, debt, equity, and property tests that cap combined leverage by occupancy and credit tier.
- Repayment has two starts. Interest payments usually begin during the draw period. Principal payments begin when the draw period ends.
- Draw periods are set in your agreement. Sources commonly describe five to 10 years of drawing, followed by a repayment period of up to 20 years.
- Qualifying has five parts. Lenders review credit, income, debt-to-income, equity, and the property itself.
- Occupancy changes the ceiling. On Lendmire’s network, an investment-property line tops out at 70% CLTV, while primary-residence and second-home lines can reach higher.
- Payment shock is the real risk. The step from interest-only to fully amortizing payments raises the monthly payment, so plan for it before the draw period ends.
What Is a HELOC, and Why Does Repayment Confuse People?
A HELOC works like a credit line, not a lump-sum loan. You get a limit, borrow against it as needed, and repay and borrow again during a set window. That window is the draw period. The repayment period follows it.
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.
The name causes the confusion. Many people hear repayment period and assume they owe nothing until it begins. Benzinga calls that term a misnomer, because payments are due during the draw period too. Those draw-period payments are often interest-only, so the balance does not shrink.
Experian describes the typical shape as a draw period of five to 10 years followed by a 20-year repayment period. Those are typical ranges, not rules. Each lender sets its own lengths in the loan agreement.
A HELOC also leaves your first mortgage in place. A cash-out refinance replaces that mortgage and reprices the whole balance. That difference matters if your first mortgage carries terms you want to keep.
What Are the HELOC Requirements?
Underwriting a HELOC runs in a fixed order: equity, credit, income and debt, the property, then documents. A failure at any step stops the file. Here is how each step works, including what Lendmire’s wholesale network looks for on equity lines placed through its select partners.
Step 1: The equity test. Lenders measure combined loan-to-value, or CLTV. That is your first mortgage balance plus the new line, divided by the home’s value. The network sets a CLTV ceiling by occupancy and credit tier, and the line must fit under it.
Step 2: The credit review. Nasdaq reports that approval generally needs a score in the mid-to-high 600s, with 700 or higher working better. Across Lendmire’s network, the floor differs by occupancy. Primary residences start at 600, second homes at 640, and investment properties at 700. The score model uses a single bureau, keyed to the primary wage earner, and the report can be no more than 90 days old at closing.
Step 3: Income and debt. Nasdaq also notes that lenders review employment and income documents and your debt-to-income ratio, or DTI. DTI is your monthly debt payments divided by your gross monthly income. On this network, the maximum DTI is 50%. Credit profiles from 600 to 679 are held to 45%, and any ratio above 45% requires a score of at least 680. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you actually borrow.
Step 4: The property. Eligible collateral includes single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not eligible. Lendmire places equity lines through two wholesale programs. The shorter-runway program pairs a 3-year interest-only draw with a 17-year repayment. The longer-runway program pairs a 5-year draw with a 25-year repayment. Modular factory-built homes are eligible only on the longer-runway program.
Step 5: Valuation. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A higher CLTV may trigger a secondary valuation. Every line above $500,000 requires a full appraisal, and you can request one on any line.
Leverage by Occupancy
The ceiling depends on how you use the property. Never read a primary-residence figure as if it applied to a rental.
| Occupancy | Minimum credit | Top CLTV | Max line |
|---|---|---|---|
| Primary residence | 600 | 90% (720+ only) | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 640 | 90% (720+ only) | $500,000 |
| Investment property | 700 | 70% | $500,000 |
Those tops are the best case. Lower credit tiers step down. A primary residence at 640 reaches 80% CLTV, and one at 600 is held to 60%. Every figure is subject to lender guidelines and a full file review.
The 70% investment ceiling is a hard line on this network, whatever higher figures you may see quoted for equity lines elsewhere.
When Does HELOC Repayment Start?
Repayment begins when the draw period ends. The date comes from your loan agreement, not from any regulator, and it is measured from closing, not from your first withdrawal. Finding it is a matter of reading the draw-period clause.
The two wholesale programs set the clock. On primary residences and second homes, you can choose between a 3-year interest-only draw followed by a 17-year fully amortizing repayment, and a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Investment-property lines run the 5-year draw and 25-year repayment structure only. Some states shorten both windows.
A few mechanics apply across both programs:
- At least 75% of the line is drawn at closing.
- Pricing floats through the draw and the repayment period. It never converts to a fixed structure.
- The longer-runway program sets a $1,000 minimum for later draws.
- Once repayment starts, you generally cannot borrow again.
Note also that the line is not interest-free during the draw. Because at least 75% is drawn at closing, you are paying interest on a large balance from the first month.
What Happens to the Payment When Repayment Begins?
The payment steps up, often sharply. During the draw you pay interest only. After it, you pay interest plus principal on a schedule meant to retire the full balance.
The Ask CFPB explainer on home equity lines says the lender may set a repayment schedule, often over ten or 20 years. Three things decide the new payment: the balance when the draw ends, the pricing at that time, and the length of the repayment term.
Picture an investor who drew most of a line to cover a down payment on a rental. The line sat on interest-only payments for five years while the balance stayed flat. In year six, the same balance has to amortize over 25 years. The payment now includes principal on top of the interest. The rental’s coverage may look very different. Your lender can model this, but you should run it yourself before the draw ends.
Because pricing floats, the payment can also keep moving during repayment. The Ask CFPB comparison of equity loans and lines notes that HELOCs usually carry adjustable pricing, so the payment varies with the balance and the market.
A simple stress test works. Take your rent, subtract the full amortizing payment on the whole balance at a higher level of pricing than today, and see whether the property still carries itself. If it only works while interest-only, the line is a bridge, not a plan.
Which Structures and Variations Exist?
Several structures change when and how repayment starts. Know which one your agreement uses before you sign.
Balloon structures. Experian notes that some HELOCs make the entire balance due when the draw period ends. In that case, repayment starts and payoff arrives on the same day. Lendmire’s network placements use fully amortizing repayment periods, but not every lender in the wider market does.
Renewal. Renewal is a lender decision, not a right.
Extra principal during the draw. Paying more than the minimum shrinks the balance before amortization begins. That softens the later payment. Benzinga notes that some lenders charge fees for early repayment, so check the agreement first.
First or second lien. The network places standalone lines in first or second lien position. A first-lien line means no other mortgage sits ahead of it. Many investors only discover the lien question after they apply.
Structure by occupancy. Primary residences and second homes can choose between the 3-year and 5-year draw structures. Investment lines get only the 5-year structure.
Where Does the General Rule Break?
The general rule says a HELOC is a flexible line against your equity. These edge cases break that picture, especially for investors.
Title and vesting. Title must be held by you as an individual or in an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest difference from a DSCR loan, which can often close in an LLC, subject to lender program eligibility. If your rental is already deeded to an LLC, you would need a vesting change or a DSCR cash-out refinance instead.
Line size above $500,000. Only primary residences can go above $500,000. The credit profile must reach 700 or better (720 on the longer-runway program), the CLTV caps at 75%, and a full appraisal is required.
Borrower exposure. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the shorter-runway program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible. Large portfolios hit this wall.
Past credit events. A bankruptcy needs four years of seasoning from discharge or dismissal on both programs. Foreclosure history splits. On primary residences and second homes, one program declines it regardless of age. The other seasons a foreclosure at seven years and a deed-in-lieu, pre-foreclosure, or short sale at four. Investment files follow the seven-and-four-year path.
Listing status. In some states, a property listed for sale, or listed within the past 60 days, is ineligible.
Value drops. If you planned to use the line as a down payment for a future purchase, a reduced line can leave you short.
Default. The Ask CFPB explainer warns that if you fall behind or cannot repay on schedule, you could lose the home. A HELOC is secured by the property, and that risk is real once you have drawn on it.
Property types. Manufactured homes are not eligible on either program, and the same goes for log homes. Those property types are not offered.
Line availability is also narrower than the DSCR footprint. Equity lines are available only in Lendmire’s 16 full-service states, while its DSCR programs cover 41 markets, including Washington, D.C.
What Does the Investor Decision Look Like?
For most investors, the question is not whether a HELOC works. The question is which tool matches the property and the plan. A HELOC underwrites you: your credit, income, DTI, and the home. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
That split shows up in practice:
- Many mortgages or hard-to-document income. If you hold many mortgages or have income that is hard to document, DTI can block a HELOC. A DSCR loan reviews the rental’s coverage instead.
- Rental equity. On an investment property, the HELOC ceiling is 70% CLTV with a $500,000 maximum line. A DSCR cash-out refinance goes up to 75% LTV on standard rentals, usually after about six months of seasoning.
- Entity ownership. If you hold rentals in an LLC, a HELOC does not fit. DSCR financing often does, depending on program guidelines.
- Home equity use. If you are drawing on your own residence to fund a down payment, the line fits, but you carry personal liability and a lien on your home.
A HELOC can also supply the down payment on a rental. Tax treatment varies; consult a qualified professional. The cleaner path is to check coverage first. Most DSCR programs start at a 1.00 coverage floor, though a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
Run both tests. Check whether you have enough equity and whether the rental has enough coverage. The strongest files clear both. The complete DSCR loans guide covers the rental-side test in depth.

Before your draw period ends, go through this checklist:
1. Find the draw-period end date and the repayment term in your agreement.
2. Check whether the structure is amortizing or balloon.
3. Model the full amortizing payment against your cash flow.
4. Decide whether to pay down principal, ask for renewal, or refinance.
5. Set your own calendar reminder. Do not rely on the lender to warn you.

Repayment period: The window after the draw ends, when you pay principal and interest and can no longer borrow.
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the home’s value.
DTI (debt-to-income): Your monthly debt payments divided by your gross monthly income.
Interest-only payment: A payment that covers interest but does not reduce the balance.
Fully amortizing: A payment schedule that pays off the entire balance by the end of the term.
Balloon payment: A structure that makes the full balance due at the end of the draw period.
DSCR (debt service coverage ratio): A rental’s income divided by its monthly payment, used to qualify investment loans on property income.
Frequently Asked Questions
Does repayment start the day the draw period ends?
Yes, on the date your agreement sets. After that date you cannot borrow, and your payment includes principal. Some agreements instead make the full balance due, so read the clause carefully.
Do I owe anything during the draw period?
Usually yes. Many HELOCs require minimum monthly payments during the draw, and those are often interest-only. On Lendmire’s network, at least 75% of the line is drawn at closing, so interest starts accruing on a large balance right away.
What credit score do I need for a HELOC?
It depends on occupancy. On Lendmire’s network, the floor is 600 on a primary residence, 640 on a second home, and 700 on an investment property. Higher scores unlock higher CLTV tiers, and the 90% ceiling on primary and second homes applies only at 720 or better. Every file is reviewed individually.
Can I get a HELOC on a rental property?
Yes, on a limited basis. Investment-property lines on this network require a 700 credit profile, cap at 70% CLTV, and top out at $500,000. The property must be held in your personal name or a revocable living trust, not an LLC.
Can the lender shrink my line before I use it?
It can, if your home’s value drops. The CFPB booklet on HELOCs says lenders may reduce the credit line in that case. Treat an undrawn line as flexible, not guaranteed.
