Cash-out versus rate-and-term refinancing explained: how to tap equity for remodeling or reinvestment and what to weigh before you refinance.
What refinancing really means
Refinancing replaces your existing mortgage with a new one, ideally on terms that better suit your goals. People refinance to lower their interest rate, change their loan term, switch from an adjustable to a fixed rate, remove mortgage insurance or access home equity. Each purpose has different costs and trade-offs, so it pays to be clear about your objective before you apply.
Rate-and-term refinance
A rate-and-term refinance changes the interest rate, the loan term or both, without taking significant cash out. Common goals include:
- Lowering the rate. This can reduce your monthly payment or total interest.
- Shortening the term. Moving from a 30-year to a 15-year loan can reduce total interest, though the monthly payment usually rises.
- Switching loan types. Converting from an adjustable to a fixed rate can provide payment stability.
- Removing mortgage insurance. If you have built enough equity, a new loan may eliminate it.
Cash-out refinance
A cash-out refinance replaces your mortgage with a larger one and gives you the difference in cash. Homeowners use it to fund renovations, consolidate higher-interest debt, invest or cover major expenses. Because you are increasing your loan balance, your payment may rise, and lenders often apply more conservative limits, such as maximum loan-to-value ratios. Think carefully about how you will use the funds, and whether the use creates lasting value.
Alternatives to consider
A cash-out refinance is not the only way to access equity. A home equity line of credit or a home equity loan lets you borrow against your home while keeping your existing first mortgage, which can be attractive if your current rate is low. These products have their own rates, fees and risks, and many have variable rates. Compare the full cost of each approach.
What lenders evaluate
Refinancing involves a new application and underwriting process. Expect lenders to review your credit, income, employment, debts, and home value through an appraisal. Your loan-to-value ratio, which compares the loan to the home's value, affects eligibility and pricing. Jumbo refinances may have stricter requirements.
Understand the costs
Refinancing typically involves closing costs, which can include lender fees, appraisal, title and escrow charges, and recording fees. Some lenders offer no-closing-cost options in exchange for a higher rate. When comparing offers, review the written Loan Estimate and look at the total cost, not just the interest rate. Ask whether you can roll costs into the loan, and understand how that affects your balance.
Consider the term reset
If you are several years into a 30-year mortgage and refinance into a new 30-year loan, you restart the clock. Even with a lower rate, you may pay more interest over the life of the loan if you stretch repayment. Ask your lender to show total interest paid under each scenario, and consider making extra principal payments if you want to preserve your original payoff date.
Think about how long you will stay
Because refinancing has costs, the benefits usually depend on how long you keep the loan. If you plan to sell in a few years, you may not recoup the expense. The next article in this series explains how to calculate your break-even point.
Tax and financial planning considerations
The tax treatment of mortgage interest depends on how loan proceeds are used and on current tax rules. Speak with a tax professional before making decisions, especially if you plan to use cash-out funds for investment or other purposes.
Protect your equity
Home equity is a valuable resource, and borrowing against it should be deliberate. Keep reserves, avoid overleveraging and make sure your plan holds up if income or values change.
