Every HELOC has two very different lives. For the first several years, it behaves like a flexible credit line — draw what you need, pay interest on the balance, repeat. Then, on a set date written into your original agreement, it becomes something else entirely: a fixed repayment schedule with a much larger required payment.
Most California homeowners open a HELOC and never read that far into the paperwork. If your line is a few years old, this is the part worth understanding now — not in year 9.
Two Phases, One Loan
A HELOC is structured in two distinct periods:
- The draw period — commonly 10 years, though some programs use 5 or 15 — during which you can borrow, repay, and re-borrow against your credit limit, generally with interest-only minimum payments.
- The repayment period — the years remaining on the loan term after the draw period ends, during which you can no longer draw new funds and must pay down both principal and interest on whatever balance you're carrying.
The draw period is the part that feels easy. The repayment period is the part that resets expectations.
What Actually Happens at the End of the Draw Period
Nothing dramatic happens on the calendar date itself — no notice arrives out of nowhere if you've been reading your statements. But the mechanics of your payment change on that date:
- New draws stop. The revolving credit line closes to further borrowing. Whatever balance you're carrying is what you'll repay.
- The payment becomes fully amortizing. Instead of interest-only, your payment is recalculated to pay off the remaining balance — principal plus interest — over whatever repayment term your agreement specifies.
- The repayment term is often shorter than you'd expect. A common structure is a 10-year draw period followed by a 15- or 20-year repayment period, but some programs compress repayment into as little as 10 years or less. The shorter the repayment window, the bigger the jump.
That combination — a full balance, now amortizing, over a compressed number of years — is why the change in required payment can be substantial. This is usually called payment shock, and it's the single most important thing to plan around.
Why the Payment Jump Can Be Large
Picture a homeowner who drew a sizable balance during the draw period and paid interest-only the whole time — a common pattern, since interest-only minimums are exactly what makes the draw period affordable. At the end of year 10, that full balance is still outstanding. None of it amortized down, because interest-only payments don't touch principal.

Now the lender needs that balance paid off within the remaining repayment term. Compare the two payment types on the same balance:
- Interest-only (draw period): payment covers interest charges on the balance only
- Fully amortizing (repayment period): payment covers interest plus enough principal to zero out the balance by the end of the term
Rolling from one to the other, on the same outstanding balance, routinely produces payments meaningfully higher than what you were used to. Exactly how much higher depends on your balance, your rate, and how many years are left to amortize it — there's no single number that applies to every line, so run your own figures rather than trusting a generic example. Our HELOC calculator is built for exactly this — it can model your current balance against a repayment-period schedule so you see the number before it arrives on a statement.
Does the Rate Change Too?
Most HELOCs carry a variable rate throughout both the draw and repayment periods, tied to an index that can move independently of the payment-structure change described above. That means two things can shift your payment at the same time: the switch from interest-only to amortizing, and whatever the index has done since you opened the line. Check your original agreement for how your specific rate is indexed, and don't assume it locks just because the draw period ends — for current pricing on new lines, see our rates page.
What to Do Before Year 10 Arrives
The good news: none of this has to be a surprise, and you have real options if you start looking before the transition hits.
Option 1: Pay down the balance during the draw period. Even modest extra principal payments while you're still interest-only reduce what has to amortize later. This is the simplest fix if your budget allows it.
Option 2: Refinance into a new HELOC. Many homeowners simply open a new line — either with their existing lender or a new one — resetting the clock to a fresh draw period. This works especially well if you still have meaningful equity and your first mortgage rate is worth protecting. See our guide on how much equity you can access in California to check whether the math still works in your favor.
Option 3: Convert to a fixed-rate home equity loan. Some lenders allow converting all or part of an outstanding HELOC balance into a fixed-rate, fixed-payment loan — trading payment uncertainty for predictability. Whether this is offered, and on what terms, varies by program.
Option 4: Cash-out refinance your first mortgage. Rolling the HELOC balance into a new first mortgage combines both debts into one fixed payment. This usually makes the most sense when your current first-mortgage rate is already close to today's market — otherwise you're repricing a loan that didn't need it. Our comparison of HELOC vs. cash-out refinance walks through that trade-off in detail.

Option 5: Let it convert and pay the repayment schedule. If the higher payment fits your budget, there's nothing wrong with simply riding out the repayment period as originally structured. Some homeowners specifically choose interest-only draw periods to match a temporary cash-flow need, then are ready for full amortization once that need passes.
A Rough Timeline
- Years 1–7 of the draw period: business as usual — draw, repay, re-draw as needed. Good time to check your statement for the exact draw-period end date; it's stated in your original loan documents.
- Year 8: start modeling what your repayment-period payment would look like on your current balance. This is early enough that refinancing or paying down principal still meaningfully changes the outcome.
- Year 9: talk to loan specialists about your options — refinance, conversion, or cash-out — while you still have a full year of runway to execute whichever one fits.
- Year 10 (or whenever your draw period ends): either your new plan is in place, or you've confirmed the repayment schedule works for your budget as-is.
Checking Your Options Doesn't Cost You Anything
If a refinance or a new HELOC looks like the right move, initial eligibility checks typically run on a soft credit pull — meaning you can see where you stand without a hard inquiry touching your score. Check your HELOC options in a few minutes, with no obligation either way.
