When you refinance your home, a new mortgage replaces your existing one. Your new lender pays off your old loan balance, releases the original lien on your property, and records a new one. From that point forward, you make payments to the new lender under new terms, whether that means a lower interest rate, a different loan length, or cash pulled from your equity. The process takes roughly 30 to 45 days from application to closing, and while the mechanics mirror buying a home in many ways, there are some key differences worth understanding before you start.
How the Old Loan Gets Replaced
The core of a refinance is a payoff-and-replace transaction. Once you close on the new mortgage, your new lender wires funds to your old lender to pay off the remaining balance. Your old lender then files a release of the original lien with your county recorder’s office, clearing the way for the new lender to record its own lien against the property. You don’t need to coordinate any of this yourself; the title company handling your closing manages the payoff, lien release, and recording.
Your old loan account closes completely. You’ll stop receiving statements from that lender, and the account will show as “paid in full” on your credit report. Your new loan is a fresh account with its own balance, rate, and repayment schedule.
What Happens to Your Escrow Account
If your old mortgage included an escrow account (money set aside each month for property taxes and homeowners insurance), that balance doesn’t just disappear. Federal rules require your old servicer to refund any remaining escrow funds within 20 business days of the loan being paid off. You’ll typically receive a check in the mail a few weeks after closing.
There is one exception. If your new loan is with the same lender, or uses the same loan servicer, the servicer can transfer your old escrow balance directly into the new loan’s escrow account, as long as you agree. This can be convenient because it reduces the amount you need to deposit into the new escrow at closing. But the servicer isn’t required to offer this option, and you’re not required to accept it.
Your new lender will set up a fresh escrow account at closing and collect an initial deposit, usually a few months’ worth of tax and insurance payments. This means you may briefly have money tied up in both the old and new escrow accounts until the refund arrives.
Closing Costs You’ll Pay
Refinancing isn’t free. You’ll pay closing costs similar to those from your original purchase, though some fees may be lower. Typical costs include:
- Origination or underwriting fee: 0.5% to 1.5% of the loan amount. On a $300,000 loan, that’s $1,500 to $4,500.
- Appraisal fee: $300 to $1,000, depending on your property’s size and location. Your new lender orders this to confirm the home’s current value.
- Title services: $300 to $2,000, covering a new title search and lender’s title insurance policy.
All told, closing costs for a refinance generally run 2% to 5% of the loan amount. Some lenders offer “no-closing-cost” refinances, but that typically means the fees are rolled into your loan balance or offset by a slightly higher interest rate. You’re still paying them, just not upfront.
This is why the math matters. If you’re refinancing to save $150 a month on your payment but closing costs total $6,000, it takes 40 months to break even. If you plan to sell or move before that point, the refinance could cost you more than it saves.
How Your Loan Terms Change
The new mortgage can differ from your old one in several ways, depending on what you’re trying to accomplish.
A rate-and-term refinance is the most straightforward version. You’re swapping your current interest rate, loan length, or both, without borrowing additional money. If rates have dropped since you got your original mortgage, this type of refinance can lower your monthly payment, reduce the total interest you’ll pay over the life of the loan, or both. You might also switch from a 30-year term to a 15-year term, which raises your monthly payment but dramatically cuts your total interest cost.
A cash-out refinance lets you borrow more than your current balance and pocket the difference. For example, if you owe $200,000 on a home appraised at $350,000, you might refinance for $260,000 and receive $60,000 in cash at closing (minus fees). You can use that money for anything: home improvements, debt consolidation, college tuition. The tradeoff is a larger loan balance and, often, a slightly higher interest rate. Lenders also charge loan-level price adjustments on cash-out refinances based on your credit score and how much equity you’re tapping, which can add to your costs.
Most conventional lenders require you to keep at least 20% equity in your home after a cash-out refinance. So on that $350,000 home, the maximum new loan would be around $280,000. Government-backed loans (FHA, VA) have their own limits.
How Refinancing Affects Your Credit
A refinance touches your credit report in three ways, all relatively minor if you manage the process well.
First, applying for a new mortgage triggers a hard inquiry on your credit report. If you shop multiple lenders for the best rate, each one pulls your credit. FICO’s scoring models treat all mortgage inquiries made within a 45-day window as a single inquiry, so there’s no penalty for comparison shopping as long as you keep your applications within that timeframe. Some older scoring models use a 14-day window instead, so submitting applications close together is the safest approach.
Second, your old mortgage account closes and a brand-new one opens. Since length of credit history accounts for about 15% of your FICO score, replacing a long-standing account with a new one can cause a small dip. This effect fades as the new loan ages.
Third, if you do a cash-out refinance and increase your total debt, the higher balance can temporarily lower your score because the amount you owe makes up about 30% of your FICO calculation.
In practice, most borrowers see a modest score drop of a few points that recovers within a few months of on-time payments on the new loan. The long-term benefit of a lower rate or reduced debt usually outweighs the short-term credit impact.
Your Payment Timeline During the Switch
One detail that catches people off guard: after closing on a refinance, you’ll likely skip a month’s payment. Mortgage interest is paid in arrears, meaning your monthly payment covers the interest from the previous month. When you close on a new loan, prepaid interest covers the days remaining in that month. Your first payment on the new mortgage isn’t due until the following month. So if you close in mid-March, your first new payment is typically due May 1.
This isn’t a free month. The interest is still accruing. But it does create a temporary gap that can feel like breathing room in your budget. Just make sure you don’t accidentally make a payment to your old lender after the refinance closes. Once the payoff is processed, that loan no longer exists.
When the Refinance Makes Financial Sense
The decision comes down to simple math. Add up your total closing costs and divide by your monthly savings to find your break-even point. If you plan to stay in the home well beyond that break-even date, the refinance pays for itself. If you’re likely to move before then, you may be better off keeping your current loan.
Refinancing also resets your amortization schedule. If you’re 10 years into a 30-year mortgage and refinance into a new 30-year term, you’re stretching your remaining payments over three decades again. Your monthly payment drops, but you could end up paying more total interest over the life of the loan. Choosing a shorter term, like 15 or 20 years, avoids this problem, though at a higher monthly cost.
For cash-out refinances, weigh the interest rate you’ll pay on the borrowed funds against the cost of alternatives like a home equity loan or personal loan. Because a cash-out refinance replaces your entire mortgage, you’re refinancing money you already owe at the new rate too, which can work for or against you depending on where rates stand.
