Refinance and HELOC: Getting Equity Out of Your Home
This page covers how to get equity out of your home: how a refinance, a HELOC, and a second mortgage each work, which situation each one fits, and why the number to compare is five-year total cost rather than the rate. You get the borrowing limits, the one-time costs, and the point where a break penalty flips the whole calculation. The goal is that you can run the math yourself before you sign.

How much can you actually pull out?
Through conventional lenders the ceiling is 80% of the property's value, minus what you still owe. Cash-out borrowing cannot be insured, so 80% is a hard line rather than a guideline.
Say the home appraises at $1,000,000 and you owe $500,000. Eighty percent is $800,000, so roughly $300,000 is available before costs. For illustration only — the real number depends on the appraisal and on what your income supports.
Two limits apply and the lower one wins. The appraisal is what a lender's appraiser says the home is worth, not what you think it is worth. And your income has to carry the larger payment at the qualifying rate.
Refinance, HELOC, second mortgage: what is the difference?
A refinance replaces your existing mortgage with a larger new one. A HELOC is a revolving line secured by the home, and you pay interest only on what you draw. A second mortgage sits behind the first and leaves the first untouched.
A refinance fits a large amount you will carry for years with a set payment. A HELOC fits amounts you cannot pin down and may repay quickly, like a renovation or business cash flow. A second mortgage fits the case where your first mortgage terms are good, the break penalty is expensive, or you need the money fast.
They price differently. A refinance is usually cheapest per dollar and carries the most one-time cost. A HELOC is generally variable. A second mortgage has the highest rate and fees and the fastest timeline, and it leaves the first mortgage alone.
How much HELOC can you get, and can it combine with a refinance?
They combine, and it is common. The revolving portion is generally capped at 65% of the home's value, and the mortgage plus the line together cannot exceed 80%.
The usual structure is a combined product: part as an amortizing term portion with a scheduled payment, part left available as a line. Lower required payment, flexibility kept.
Watch the payment structure. A HELOC's minimum payment is generally interest only, so the balance does not come down on its own. That convenience is what makes it expensive over time, and it has nothing to do with the rate.
Why does the five-year total cost differ more than the rate does?
Because the rate is one line of the bill. What you add up is five years of interest, the one-time costs, and any penalty to break the existing mortgage.
One-time costs include the appraisal, legal or title fees, and discharge fees. Second mortgages and private deals add lender fees and broker fees. On a smaller cash-out those can outweigh several years of rate difference.
The penalty is the line people skip. Breaking a fixed term partway through to refinance can cost enough to erase the whole benefit, and the calculation varies widely between lenders. The right comparison is total dollars out the door over your real holding period, per option, side by side.
Refinance now, or wait for maturity?
It comes down to the penalty and how urgent the need is. Refinancing at your maturity date generally avoids a penalty, which makes it the cheapest moment to do it.
If the money is needed now there are two routes. Pay the penalty and refinance, if the total still works. Or bridge with a HELOC or a second mortgage and fold it into the main mortgage at maturity. The second route costs more in interest short term and leaves the first mortgage alone.
Which one wins depends on the amount, the time left on the term, and how your lender calculates the penalty. That is a calculation, not a preference.
Does the lender care what the money is for?
Most will ask, because the purpose changes how they read the risk. Debt consolidation, renovations, an investment property, or helping a child with a down payment are all common and generally acceptable.
Consolidating high-interest cards and loans is the easiest case to prove out: several expensive balances become one, and the total monthly obligation usually drops noticeably. The condition is that you stop running the cards back up. Otherwise in six months you have both debts.
If the money is going into a business or an investment, the tax treatment of the interest can differ. That is a question for your accountant. I only speak to the lending side.
Who is this hardest for, and what should they do?
Three groups: self-employed borrowers who file low, anyone with credit damage, and owners of properties lenders see as hard to sell — remote, very small units, unauthorized suites, or a building with known problems. Cash-out means full requalification, stress test included. There is no way around the income test.
Do the value side first. Pull recent comparable sales rather than working off list prices. If credit is the issue, clear the delinquencies and bring revolving balances down; that usually shows up within a few months. If you are self-employed, get two years of filings and financial statements in order, or use a lender that reads bank statements.
When conventional does not work, B and private lending exist. They cost more and are generally a bridge. Do not take one without an exit plan, meaning specifically how you get back to a conventional lender within a year or two. Bridges without exits are where this gets expensive.
How long does it take, and what is needed?
Three to five weeks in most cases, and where it slows down is the appraisal and the legal step. A second mortgage can be compressed into one to two weeks when speed matters, and you pay for that.
Documents are generally income confirmation, the property tax bill, your current mortgage statement, home insurance, and leases if there is rental income. Self-employed adds two years of filings and financial statements.
This is general information, not advice on your specific situation. What the three routes actually cost is something you have to work out on your own numbers.
Common questions
Does refinancing reset the amortization?
It can. A refinance is legally a new mortgage, so the amortization gets set fresh rather than continuing to count down from where your old one left off. Stretching it back out to a longer amortization lowers your monthly payment, which is often the whole point of refinancing, but it also increases the total interest paid over the life of the loan. Neither of those is automatically the wrong choice — it depends on why you're refinancing in the first place. If the goal is lower monthly cash flow, a longer amortization is doing its job; if the goal is paying the home off faster, it's working against you.
Is a HELOC rate fixed?
Generally variable, tied to prime, which means the rate — and your interest cost — moves when prime moves, not on a fixed schedule you control. Most lenders let you convert part of the outstanding balance into a fixed, amortizing portion, which behaves more like a traditional mortgage payment instead of interest-only, but the terms for doing that differ by lender and aren't always advertised up front. If you're using a HELOC for a large, long-term expense rather than short-term flexibility, it's worth asking about this conversion option specifically, since leaving a large balance fully variable exposes you to every rate move going forward.
The home has gone up a lot. Will they use today's market value?
They use the lender's own appraiser, working from recent comparable sales in your immediate area — not the list price you've seen on a real estate site, and not the assessed value on your property tax notice, which tends to lag well behind the actual market. Comparable sales can also move faster or slower than general market talk suggests, so a number you've heard from a neighbour or a listing isn't a reliable stand-in for what an appraiser will land on. If the appraisal comes in lower than expected, that changes how much equity is available to pull out, so treat any number before the appraisal as a rough guess, not a plan.
Does owning a rental change the math?
The refinance structure itself is the same, but lenders treat your rental income very differently from one to the next, and that difference can matter more than almost anything else in the file. Some count a portion of the rent as straightforward income added to what you earn; others offset it directly against the rental property's own mortgage payment instead, which produces a very different qualifying number. A file that gets declined at one lender on this basis can pass easily at another, purely because of how that lender's rental-income policy is written, not because anything about your situation changed. This is exactly the kind of thing worth checking across several lenders rather than assuming one no means no everywhere.
What happens if a second mortgage cannot be repaid at maturity?
Second mortgage terms are typically short, so when maturity arrives you generally have three paths: renew the second mortgage as-is, fold it into a new first mortgage through a refinance, or pay it out from savings or a sale. Which one is realistic depends heavily on what's happened to your income, credit, and the property's value since you took the second mortgage out — a plan that looked fine going in can look very different a year or two later. The mistake to avoid is treating the second mortgage as a problem for future-you to solve; decide which exit you're aiming for before you take it, not once the maturity date is already close.
Can you refinance after retiring?
Generally yes, but it depends heavily on how your income is counted once regular employment income is gone. Most lenders will consider pension income, registered account withdrawals, and investment income, but exactly how each one is weighted — and whether withdrawals need to show a pattern of regularity first — differs by lender and isn't always obvious from their public rate sheet. This is one of the areas where taking a single lender's no as a final answer costs the most, since retirement-income policies vary more than almost any other category. Bringing a clear picture of every income source, not just the largest one, usually opens up more options than expected.
