HELOC vs. Fixed Second Mortgage vs. Cash-Out Refinance
Keep your first mortgage and borrow separately, or replace it with a larger loan. Compare how you receive the money, the full repayment plan and the debt you will still owe.
The difference at a glance.
| What to compare | Home equity loan | HELOC |
|---|---|---|
| Access to money | One lump sum | Draw as needed up to a credit limit during the draw period |
| Interest rate | Usually fixed; adjustable products also exist | Usually variable; some allow fixed-rate conversions |
| Payments | A fully amortizing fixed-rate loan has a scheduled principal-and-interest payment | May begin with interest-only payments, then require principal repayment; terms vary |
| Interest charged | On the full outstanding loan balance | On what you have drawn, plus any applicable fees |
| Your first mortgage | Generally stays in place as a separate loan | Generally stays in place as a separate loan |
| Reusing funds | Usually requires a new loan | Generally available during the draw period, subject to the agreement |
| Costs to ask about | Origination, valuation, title, closing and prepayment fees | Closing, annual, draw, inactivity and early-closure fees |
| Main tradeoff | Pay interest on the lump sum even if you have not spent it | Rate changes, payment increases and possible restrictions on future draws |
KNOWN COST

If your final budget is known and spending begins soon, a fixed loan may make budgeting easier. Compare fees and total interest, and keep a cushion for overruns.

A HELOC can let you draw for each phase instead of borrowing it all immediately. Plan for a higher rate, the end of the draw period and the possibility that future draws may be restricted.
HELOC, fixed second mortgage or cash-out refinance?
A fixed second mortgage can suit a known borrowing amount and a predictable payoff plan. A HELOC can suit spending in stages, with more uncertainty about future payments. A cash-out refinance replaces your existing first mortgage, so compare its effect on the entire balance. The right comparison starts with your current mortgage, how much cash you actually need and when you expect to repay it.
A HELOC and a home equity loan are both commonly second mortgages when you keep an existing first mortgage. On this page, “fixed second” means a separate, fixed-rate home equity loan with scheduled principal-and-interest payments. Other structures exist; the actual contract controls.
| Decision | Fixed second mortgage | HELOC | Cash-out refinance |
|---|---|---|---|
| Money received | One lump sum | Draws during an agreed borrowing period | Cash from a larger replacement mortgage, after payoffs and costs |
| Existing first mortgage | Normally stays in place | Normally stays in place | Paid off and replaced |
| Payment structure | Fixed principal and interest for the stated term | Often variable; draw and repayment phases may differ | Depends on the new loan's rate, term and features |
| Question that matters | Will I use the lump sum soon and follow the payoff schedule? | Can I afford a higher rate and principal repayment later? | What happens when the new terms apply to my entire first-mortgage balance? |
| Compare costs | First loan plus second loan, fees and remaining balances | First loan plus actual draws, future payments, fees and remaining balances | New loan payments, fees, term and remaining balance |
A $50,000 borrowing example: compare five years, not one payment
Illustration only: a homeowner wants $50,000 now and already owes $250,000 on a fixed first mortgage with 25 years remaining at 3.50%. Its principal-and-interest payment is about $1,251.56. The choices below provide the same $50,000 and start with $300,000 of total home-secured debt.
- Fixed second: $50,000 at an illustrative fixed 9.00% annual percentage rate (APR), repaid in 120 monthly principal-and-interest payments of approximately $633.38.
- HELOC: $50,000 drawn immediately at an illustrative variable 8.50% APR. The example holds that rate unchanged, allows interest-only payments for 60 months and assumes no additional draws. A real variable APR can increase.
- Cash-out refinance: a new $300,000 mortgage at an illustrative fixed 6.50% APR, repaid in 360 monthly principal-and-interest payments of approximately $1,896.20.
To isolate the payment and payoff differences, this example assumes no points, loan fees or other finance charges, and monthly interest at annual rate ÷ 12. The new fixed-loan interest rates therefore equal the illustrative APRs shown. There is no down payment in this refinance/equity illustration. Fees and daily accrual in real offers change the figures. These assumptions are not current rates, available programs or an offer to lend.
| After five years | Keep first + fixed second | Keep first + HELOC | Cash-out refinance |
|---|---|---|---|
| Starting combined monthly principal and interest | $1,884.94 | $1,605.73, including interest-only HELOC payment | $1,896.20 |
| Interest over 60 months | About $59,409 | About $62,145 | About $94,605 |
| Total principal still owed | About $246,313 | About $265,801 | About $280,833 |
The smallest initial payment leaves more debt than the fixed-second option in this example. The HELOC balance remains $50,000 because its modeled payments cover only interest. If that balance then amortizes over 120 months at an unchanged 8.50% APR, its payment becomes about $619.93 instead of $354.17. A higher rate would increase it further. The original first mortgage still has its own payment.
All amounts are rounded. Taxes, homeowners insurance, mortgage insurance, association dues, tax effects, fees, new draws and extra payments are excluded; total housing payments would be higher. The examples have different payoff dates. A five-year cost comparison does not describe their lifetime costs, and changing the assumptions can change which option looks favorable. Before choosing, add actual fees and compare the balances and costs over your own likely timeline.
Mike's approach: protect the borrowing plan, not just the first rate
I help Kansas and Missouri homeowners compare the existing mortgage with the new borrowing as one plan. A low first-mortgage rate is worth considering, but it does not automatically make a second loan the best choice. Bring the current balance, rate, remaining term, amount you need and a comfortable monthly budget. We can compare cash flow now, the payment later and the debt still owed when you expect to sell or repay.
Use the fixed home equity loan calculator for a scheduled-payoff example, the HELOC rate scenarios below for payment sensitivity, and the first-mortgage versus cash-out comparison for a shared time horizon.
Exceptions to discuss before borrowing
- Future access is conditional. A HELOC lender can restrict or freeze draws in certain circumstances. Do not treat unused credit as guaranteed emergency cash.
- Contract details matter. Ask about index and margin, rate caps or floors, fixed-rate conversion terms, draw and repayment periods, balloon payments, fees and early-closure conditions.
- Qualification is separate from equity. An estimated home value minus loan balances is not an approved borrowing limit. Income, credit, liens, property and lender rules still matter.
- Debt consolidation changes the risk. Moving unsecured debt onto your home can put the home at risk and can cost more if repayment stretches out. Compare alternatives and the full payoff plan.

What could a variable rate do to my payment?
This simplified example models interest-only payments during a HELOC draw period. Your lender may require principal payments and charge fees. It is not a full repayment forecast or a rate quote.
Ask about the payment after the draw period.
An interest-only payment does not pay down principal. When repayment begins, the payment can rise because principal becomes due, even if the rate stays the same. Ask about the index, margin, adjustment frequency, lifetime cap, any rate floor and whether a balloon payment is possible.
Good questions. Clear answers.
Is a HELOC always variable?
No. Many HELOCs have variable rates, and some provide a fixed-rate option for part or all of the drawn balance. Ask about conversion fees and how the fixed portion is repaid.
Which is better for debt consolidation?
A known balance and a fixed payoff schedule may fit a home equity loan. A HELOC needs a clear repayment plan and discipline around new draws. Neither is automatically less expensive or safer than unsecured alternatives.
What amount should I enter in the calculator?
Enter the amount you expect to draw and use, rather than the full credit limit. For example, if you are comparing a $50,000 project, enter $50,000 to see the illustrative interest-only payment at different rates.
How can I compare this with a fixed monthly payment?
Use our home equity loan calculator with the same borrowing amount, then try the rate and repayment term you want to compare. Bring both estimates to Mike to review the payment schedule, fees and timing for your project.
