Most people believe they need a big cushion of equity before they can refinance. That belief keeps a lot of capable homeowners from even asking the question, and it is only partly true. How much equity you actually need depends entirely on the kind of mortgage refinance you are doing. For some, the bar is 20%. For others, it is close to zero. The system rarely explains the difference, so here it is in plain terms.
First, what "equity" and LTV really mean
Equity is the part of your home you own outright. It is your home's current value minus what you still owe. A house worth $400,000 with a $280,000 balance has $120,000 in equity, or 30% of the value.
Lenders usually talk about the same thing from the other direction, using loan-to-value, or LTV. That is your loan balance divided by the home's value. The Consumer Financial Protection Bureau describes LTV as a core measure of how much you are financing against the property, and it drives a lot of what a refinance will cost you. In the example above, 30% equity is the same as a 70% LTV. When you read "you need 20% equity," that is the same as "you need to stay at or below 80% LTV."
Hold onto that translation. It is the key to every rule that follows.
The equity you need depends on the refinance type
There is no single equity requirement, because "refinance" covers a few different transactions with different rules.
Rate-and-term refinance: often less than you think
A rate-and-term refinance replaces your current loan with a new one to change the rate or the term, without pulling out cash. Because you are not increasing what you owe against the home, the equity bar is lower than most people expect. Many conventional rate-and-term refinances are possible even when your equity is modest.
There is a catch worth understanding. On a conventional loan, if your equity is under 20%, meaning your LTV is above 80%, you generally have to carry private mortgage insurance, or PMI. You can still refinance. You just pay PMI until you reach that 20% mark. So the real question is often not "can I refinance" but "will I owe PMI, and is the refinance still worth it after that cost."
Cash-out refinance: the 20% cushion
A cash-out refinance is different. You take out a new, larger loan and pocket the difference. Here the equity requirement is real, because lenders want you to keep a stake in the home after you pull cash out.
On most cash-out refinances, you need to leave a cushion of equity behind, commonly around 15% to 20%, which caps the new loan near 80% to 85% of the home's value. The CFPB notes that lenders typically require you to keep a minimum amount of equity, often in that range, after a cash-out refinance. So if your home is worth $400,000, an 80% ceiling means the new loan tops out near $320,000, and whatever you owe below that is what you can access, minus costs.
Streamline and VA options: sometimes little or no equity
This is where the "you need 20%" myth falls apart completely.
If you have a VA loan, the VA's Interest Rate Reduction Refinance Loan, its streamline refinance, is built to lower your rate with minimal friction. It typically does not require a new appraisal and does not set a conventional equity hurdle, which means veterans with little equity can often still refinance. For those who want to tap equity, a VA cash-out refinance can allow qualified veterans to borrow against a larger share of the home's value than a conventional cash-out would, up to and including the full value in some cases. You can read the VA's own overview of these programs at va.gov.
For veterans, that benefit is not a favor. It is something earned through service, and it changes the equity math in your favor in a way conventional borrowers do not get.
Why chasing the lowest equity requirement can backfire
It is tempting to borrow right up to the maximum the rules allow. That instinct deserves a second look, because equity is not just a qualifying hurdle. It is your safety margin.
The more you borrow against your home, the higher your LTV, and a higher LTV generally means more cost: PMI when you cross 80% on a conventional loan, and pricing that reflects the added risk. Drain your equity to the last allowable dollar and you raise your payment, thin your cushion, and leave yourself less room if home values dip or life throws a bill at you.
The smarter frame is the full picture, not the maximum. A refinance is worth doing when the new payment, the closing costs, the insurance you may owe, and the equity you keep all add up to a better position over the time you plan to stay. Sometimes the strongest move is to leave more equity in place, avoid PMI, and take a cleaner loan, even if the rules would let you borrow more.
If your goal is to consolidate higher-cost debt, that same discipline holds. CFPB research has found that cash-out borrowers most often use the proceeds to pay down other debts. Turning expensive balances into a single, lower mortgage payment can genuinely help, but only if you keep a healthy equity margin and understand the full cost of the new loan, not just the relief of the moment.
How to figure out where you stand
You can estimate your position in a few minutes. Start with a realistic value for your home. Subtract your current balance to find your equity. Divide the balance by the value to find your LTV.
Then match it to your goal. If you want a rate-and-term refinance and your LTV is at or under 80%, you are likely clear of PMI. If your LTV is higher, you can probably still refinance, but check whether PMI changes the math. If you want cash out, see how far your balance sits below roughly 80% of value, since that gap, minus costs, is a rough estimate of what you can access. And if you have a VA loan, know that the usual conventional equity rules may not apply to you at all.
These estimates will not replace a full review, but they tell you quickly whether a refinance is in reach and which type fits.
Where GoodLoan comes in
We would rather help you find the refinance that leaves you in a stronger position than push you toward the biggest loan the rules permit. A GoodLoan loan officer can look at your value, your balance, your equity, and your actual goal, then show you which refinance path fits and what it truly costs, including any PMI or fees, before you decide anything. If keeping more equity serves you better, we will tell you.
The first step is small and comes with no obligation: a short conversation to run your numbers and see what is realistic. If a refinance moves you forward, you will understand exactly why. If it does not, you will know that too.
Frequently asked questions
How much equity do I need to refinance my mortgage? It depends on the type. A conventional rate-and-term refinance can often be done with modest equity, though under 20% equity usually means paying PMI. A cash-out refinance generally requires you to keep about 15% to 20% equity. VA streamline refinances often require little to no equity and no appraisal.
Can I refinance with less than 20% equity? Usually yes. For a rate-and-term refinance you can often qualify with less, but on a conventional loan you will typically carry PMI until you reach 20% equity. VA borrowers may have options that do not follow the conventional equity rules at all.
How is equity different from loan-to-value? They describe the same thing from opposite sides. Equity is the share of the home you own; LTV is the share you still owe. If you have 25% equity, you have a 75% LTV. Needing "20% equity" is the same as staying at or below 80% LTV.
Do I need an appraisal to refinance? Often, but not always. Many refinances use an appraisal to confirm current value and your equity. VA streamline refinances typically skip the appraisal, which removes a common cost and can make refinancing possible even with limited equity.
Should I always borrow the maximum a refinance allows? No. Borrowing to the maximum raises your LTV, your payment, and often your costs, while shrinking your safety cushion. Leaving more equity in place can mean avoiding PMI and holding a stronger financial position, which is frequently the better outcome.
How do I know which refinance fits my situation? Estimate your equity and LTV, then match them to your goal of lowering a rate, changing a term, or taking cash out. A GoodLoan loan officer can confirm which path fits and what it costs before you commit.
