The Quick Read: A fixed home equity loan is the usual way to turn a variable HELOC balance into a steady payment. It works through either a lock written into your existing line or a separate new loan that pays the line off. Which lender fits depends on contract terms, the property’s occupancy, and your credit profile. Equity lines placed through the wholesale network Lendmire works with float in price through both the draw and repayment periods and never convert to fixed, so a fixed payment there means a new loan.
- A lock inside your current line only exists if your original agreement includes it.
- A new fixed-rate second lien or a DSCR refinance is a fresh underwriting event, not a switch you flip.
- On an investment property, the network’s equity-line ceiling is 70% combined loan-to-value, with a 700 minimum credit score.
- Expect the fixed option to carry a premium over the floating payment it replaces.
- The strongest exit for a rental is often a long-term fixed refinance that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Key Terms Defined
HELOC (home equity line of credit): A revolving line secured by your property, with a draw period when you borrow and a repayment period when you pay it back.
Fixed-rate conversion option: A contract feature that lets you convert all or part of your drawn balance to fixed terms for a set period.
Home equity loan: A lump-sum loan, usually fixed, secured by a second lien on the property.
Second lien: A loan that sits behind your first mortgage in repayment priority.
CLTV (combined loan-to-value): Your first mortgage plus the new loan or line, divided by the property’s value.
DSCR (debt service coverage ratio): Monthly rent divided by the monthly principal, interest, taxes, insurance, and any association dues on the property.
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.
How Does a HELOC Balance Become a Fixed Payment?
There are two mechanics. Either the line itself lets you lock a slice of the balance, or you replace the line with a new loan. Everything else is a variation on those two.
The lock route starts with your original agreement. The option usually has to be in the contract from day one. If it is there, you pick an amount, pick a term, and the locked slice becomes its own fixed loan with its own payment. The rest of the line stays variable. Lenders that allow locks often set a minimum amount per lock. CBS News puts typical minimums at roughly $2,000 to $5,000, depending on the lender.
Fees vary. Some lenders charge a lock fee and some do not. Early-termination charges are a separate risk worth reading for before you sign.
A lock inside an existing account usually does not require a full re-underwrite, because the option is part of the account you already hold. Contracts differ on whether paying down a locked slice frees up room on the line again. Ask before you assume it does.
The replacement route means a new lender, or your current one, originates a fixed-rate home equity loan or a cash-out refinance. That loan pays off the line. Because it is a new loan, it gets a new application, new credit review, and a new valuation decision.
Three Routes Side by Side
| Factor | Lock inside the line | New fixed second lien | DSCR refinance |
|---|---|---|---|
| Needs a new loan | No | Yes | Yes |
| Balance converted | All or part | Whole payoff | Whole payoff |
| Line stays open | Usually yes | No | No |
| Underwriting | Light, contract-based | Full file review | Property rental income focus |
| Works with an LLC | Contract-dependent | Often individual title | Subject to lender program eligibility |
The DSCR refinance column, and the LLC row in particular, matters most for investors who hold rentals in an entity. Many equity-line programs want the individual borrower on title, while DSCR programs are built for investor ownership structures.
What Lenders Look For on a New Equity Line
If you are moving a balance to a new lender, the guidelines differ sharply by occupancy. These figures come from the wholesale network Lendmire brokers through. They are eligibility ranges, subject to lender guidelines and full file review, and Lendmire is the broker, never the lender.
On an investment property, the combined ceiling is 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats across both periods and never converts to fixed.
On a primary residence or second home, the ceilings run higher. A primary residence reaches 90% CLTV only at a 720 credit profile or better, and then only up to $500,000. A second home also reaches 90% at 720 or better. Primary residences and second homes can also choose a 3-year draw with a 17-year repayment.
Other file requirements apply across the network:
- Debt-to-income: 50% maximum, with a lower cap for credit profiles from 600 to 679.
- Qualifying payment: calculated on the interest-only payment at the maximum draw.
- Valuation: lines at or below $500,000 ordinarily use an automated valuation, and a borrower can request a full appraisal.
- Title: held by the individual borrower or a revocable living trust. LLCs, corporations, and partnerships cannot hold title on these lines, subject to program terms.
- Exposure: a borrower is limited to three lines, and more than 15 financed properties makes a borrower ineligible.
- Property types: single-family, 2-4 units, PUDs, townhomes, and condominiums are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
These equity lines are written in 16 states, which is narrower than the 41-market DSCR footprint (40 states plus Washington, D.C.) A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
Because a fixed home equity loan is a separately originated second lien, its guidelines belong to whichever lender writes it. A broker that shops several wholesale lenders can match the scenario to that lender’s program. That matters more than any single name.
Where the General Rule Breaks
The tidy story is that you call your lender, pick a fixed term, and you are done. Several edge cases break it.
Investment-property lines are scarce. Many lenders offer equity lines only on primary residences. Investors often find that a non-owner-occupied second lien is a closed-end loan rather than a revolving line, which already makes it fixed.
The contract may simply lack the option. The federal framework only requires that a lender disclose a conversion option if one exists. It does not require any lender to offer one. Under Regulation Z’s staff commentary, the option is treated as a variable-rate feature that must be disclosed, and it does not by itself make the converted rate a promotional rate. No option means your choices are a lender modification or a new loan.
Timing can shut the door. Some lenders allow a lock only during the draw period. Others allow it in repayment, with the locked term capped at the time remaining. Read the clause, because it varies by contract.
A fixed-rate label does not decide the product. A line called a fixed-rate HELOC is usually a variable line with fixed slices. Trade coverage in HELN News points out that a product that fails the open-end credit definition is treated under closed-end rules. So the name on the brochure is not what governs it.
Closing the line has costs. Some lenders charge early-closure fees if you refinance a line out soon after opening it. Check that before you pay off a line.
Lines can be frozen or reduced. Lenders can freeze or reduce an open line if property values fall. A line that looked like permanent access to capital can shrink at the worst time.
What Does Certainty Cost?
Fixed costs more than variable at the moment you lock. The CFPB’s HELOC brochure says the fixed rate is typically higher than the variable rate, though more predictable. You are paying for predictability, not a discount.
Whether that trade is worth it depends on three things. The first is how long you will carry the balance. The second is how much a payment swing would hurt your coverage on the rental. The third is whether you plan to refinance soon anyway. Many investors use a line short-term to bridge a purchase or a rehab and exit with a refinance. For those borrowers, paying to lock a balance they will retire soon rarely changes the outcome.
The Draw-Period Clock
The draw-to-repayment jump is the real trap. During the draw period, many lines require interest-only payments. When repayment begins, the balance starts amortizing, and the payment rises even if nothing else changes.
On a rental, that matters because it can compress your cash margin all at once. Picture an investor holding a duplex with a HELOC balance used as the down payment on another property. While the line is interest-only, the rent covers the debt with room to spare. When repayment starts, the same rent may cover it far less comfortably.
Converting earlier in the draw period gives you the most options, because a lock or a refinance is easier to arrange while the line is healthy. Waiting until repayment begins can narrow them, since some contracts only allow a lock during the draw. A refinance is still available at any point, subject to lender guidelines and credit approval.
The DSCR Exit: Replacing the Line With a Fixed Rental Loan
For many investors, the cleanest way out of a variable second lien is not another second lien. It is a refinance on the rental itself. A DSCR loan is designed for non-owner-occupied investment properties. Because it is a business-purpose investor loan, it is reviewed differently from a standard owner-occupied mortgage. The complete DSCR loans guide covers the full structure.
Here is how it works across the network. A DSCR cash-out refinance tops out around 75% LTV on a standard rental. About 6 months of seasoning is the common expectation. Many programs want a score near 660, a 620 floor exists in parts of the network, and 700 and above opens the strongest leverage tiers. Standard programs lend up to $3,000,000, and above $2,500,000 the network generally holds to 30-year fixed structures.
The spine of the product is the 30-year fixed. Extended terms such as 40-year and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want them.
Coverage works like this: the lender compares monthly rent to the full monthly obligation. A ratio of 1.00 is where many select programs start, so it is a floor for specific programs, not a universal standard. Stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Reserves vary by lender, leverage, and loan size, commonly around 6 months of principal, interest, taxes, insurance, and dues. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months.
Consider a rental whose rent covers the full monthly obligation by a ratio of roughly 1.25x today. A cash-out refinance pays off the line, and if the same loan also pays off the first mortgage, the result is a single fixed-rate loan in place of the two. Coverage then stays put regardless of where the variable benchmark moves.
Clearing 1.00 is not the same as positive cash flow. The calculation includes only rent against principal, interest, taxes, insurance, and dues. Repairs, vacancy, management, utilities, and capital expenses all sit outside it, so size your margin accordingly.
A larger down payment can lift coverage by shrinking the payment. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Questions to Ask Any HELOC Lender Before You Convert
Use this order. It sorts out the fit before you spend on an application.
1. Does my agreement include a conversion option? If not, ask whether a modification exists.
2. Is the property treated as an investment property? Occupancy decides which program applies.
3. What is the minimum lock amount, and how many locks can be open at once?
4. Is there a lock fee, and what are the early-termination terms?
5. Can I lock during repayment, or only during the draw?
6. Does the line stay open, and does paying down a locked slice restore availability?
7. Will a new loan need a new valuation, and what does it need from my credit file?
8. Can the property be held in my entity, or must it sit in my personal name?
If you are switching institutions with a balance still open, Lendmire’s article HELOC vs. Home Equity Loan When Switching Banks With an Open Balance walks through the payoff logic.
Which Route Fits Your Situation?
Choose a lock if your contract has the option, your balance is modest, and you plan to keep carrying it for a while.
Choose a new fixed second lien if you want a lump-sum, amortizing loan, hold the property in your own name, and do not need the line kept open.
Choose a DSCR refinance if the rental has solid coverage, you want one long-term fixed structure, or the property sits in an LLC, subject to program terms.
Stay variable if you will retire the balance soon, because the cost of fixing it may outweigh the benefit.
Frequently Asked Questions
Can I convert a HELOC balance to a fixed rate on a rental property?
Only if your agreement includes a conversion option or you replace the line with a new loan. Many equity-line programs are written for primary residences, so rentals often need a different route. On the wholesale network Lendmire works with, investment equity lines never convert to fixed, so a fixed payment means a separately originated second lien or a DSCR refinance.
Does converting close the line?
A lock inside the line usually leaves it open, with the locked slice amortizing as its own loan. A new home equity loan or refinance that pays the line off closes it. Some lenders charge early-closure fees, so read the terms before you pay it off.
Can I convert just part of the balance?
Often yes, when the contract allows locks. Lenders commonly set a minimum per lock, and CBS News reports typical minimums around $2,000 to $5,000. The unlocked remainder stays variable.
What credit score and leverage apply to a new investment equity line?
Across the network, an investment-property line needs a 700 minimum score and tops out at 70% CLTV, with a maximum line of $500,000. A primary residence reaches 90% CLTV only at a 720 profile or better. Every figure is subject to lender guidelines and full file review.
Is a DSCR refinance a good way to pay off a HELOC?
It can be, when the rental has enough coverage and you want a long-term fixed structure. A cash-out DSCR refinance generally tops out around 75% LTV on a standard rental and commonly expects about 6 months of seasoning. Eligibility depends on credit, reserves, the property, and the lender.
