Mortgage recasting: What to know before you reamortize

Consumers should independently verify that any services, products, or programs referenced meet their needs and comply with applicable requirements.

Mortgage recasting can give you a lower required principal and interest payment without replacing your current mortgage by refinancing.¹ After you make a substantial payment toward principal, your mortgage servicer recalculates the payment using the lower balance, existing interest rate, and time left on the loan.

Recasting is one way to lower your mortgage payment, but it isn’t the right fit for every loan or financial goal. Before moving forward, compare the expected payment change with the amount of cash required, the servicer’s fee, and other ways you could use the money.

Key takeaways:

• A mortgage recast recalculates your required principal and interest payment after a substantial principal reduction. Your existing interest rate and remaining loan term stay the same.
• Eligibility, minimum principal reductions, fees, and processing times depend on the loan and servicer. Rocket Mortgage has specific requirements covered below.
• Recasting can create more room in your monthly budget, while making an extra principal payment without recasting may help you pay off the loan sooner.

What is a mortgage recast?

A mortgage recast occurs when you make a substantial principal payment and ask your servicer to recalculate the required monthly principal and interest payment using the new balance. The calculation uses your current interest rate and the number of months remaining in the original loan term.

Reamortization describes the calculation your servicer uses to complete a recast. The terms aren’t exact synonyms because a payment can also be recalculated in other circumstances, such as when the interest rate on an adjustable-rate mortgage changes.

A recast changes only the scheduled principal and interest part of your mortgage. Property taxes, homeowners insurance, private mortgage insurance, and other amounts collected through an escrow account are separate. Your monthly payment may not decrease by the same amount as the principal-and-interest payment.

Some current conventional loans may be eligible for recasting. At Rocket Mortgage, qualifying conforming loans associated with Fannie Mae or Freddie Mac may be recast. Government-backed mortgages aren’t eligible.

When should you consider recasting your mortgage?

Recasting may be worth exploring when you have a substantial amount available to put toward the loan and want a lower mortgage payment without giving up your current interest rate. The money could come from savings, an inheritance, a work bonus, or proceeds from selling another home.

A recast may also appeal to someone who purchased a new home before selling their previous one. After the sale, they could apply the proceeds to the new mortgage and ask the servicer to recalculate the payment.

Before committing the money, consider how much accessible savings you’ll have left and whether reducing the required payment matters more to you than paying off the mortgage as quickly as possible. Ask your servicer for an estimated new payment before sending funds intended for a recast.

How does recasting a mortgage work?

Although servicer procedures differ, a standard mortgage recast generally follows these steps:

1. Confirm that your loan is eligible: Contact your mortgage servicer, the company that collects your payments and manages your account, to ask about its requirements for your loan type, payment history, and principal reduction.
2. Make a qualifying principal reduction: Follow the servicer’s instructions so the money is applied to the unpaid principal balance rather than treated as an early scheduled payment.
3. Request the recast: A large principal payment may not trigger a recast automatically. You’ll generally need to submit a separate request.
4. Pay the recasting fee: The amount depends on the servicer. Rocket Mortgage charges $250.
5. Wait for the new payment: The servicer reamortizes the reduced balance using the existing interest rate and remaining term. Continue making your current payment amount until the new payment is reflected on your statement.

How to start the recasting process

Once you decide a recast may be something you want to look into, contact your servicer. They can give you information on how it works based on the following:

• Your current principal balance
• Your loan type
• The amount you plan to put toward principal
• Whether the loan is eligible
• The required minimum principal reduction
• Any loan-age or payment-history requirements
• The recasting fee
• The expected processing time
• The date the new payment would take effect
• Whether the principal reduction could affect your private mortgage insurance

When you speak with your servicer, have them explain how to submit an additional principal payment. Confirm that the entire amount will be applied to principal, and have them explain how to submit the separate recast request.

This step matters because an extra payment and a recast aren’t the same transaction. The extra payment reduces your balance. The recast changes the required payment schedule after that reduction.

Benefits of mortgage recasting

The potential benefits of recasting depend on the size of your principal reduction, the remaining balance and term, and your servicer’s policies. Ask for an estimate based on your actual loan before deciding.

Lower monthly mortgage payments

A recast spreads the reduced principal balance across the months remaining in the loan term. Because there’s less principal to repay, the required principal-and-interest payment decreases. Your interest rate doesn’t have to change for the payment to go down.

Remember that a recast doesn’t fix every part of the total mortgage payment. Taxes and insurance can change, and mortgage insurance may continue unless you separately qualify to have it removed

Potential interest savings

The principal payment that precedes the recast can reduce the interest you pay over time. Interest is charged based on the unpaid balance, so lowering that balance means less principal is subject to future interest charges.

The balance reduction, not the act of recasting, creates the potential interest savings. If you make the same principal payment without recasting and continue paying the original amount each month, you may pay off the mortgage sooner and reduce more interest than you would by making only the new, lower recast payment.

Possible PMI removal

A large principal payment may move a conventional loan closer to the point where you can request cancellation of private mortgage insurance (PMI). You may ask your servicer to cancel PMI when your principal balance reaches 80% of the home’s original value, although other conditions can apply.

A recast doesn’t remove PMI automatically. Ask your servicer whether you qualify for cancellation and whether it needs additional documentation or a valuation.

No credit check or appraisal

Because a standard recast changes the payment schedule on an existing mortgage instead of creating a new loan, it typically doesn’t involve meeting credit score requirements, an appraisal, or income documentation. Servicer policies may differ.

Disadvantages of mortgage recasting

A lower required payment can be useful, but it comes with trade-offs. Review what a recast can’t change before moving money in your home loan payment structure.

Your interest rate does not change

Recasting keeps your existing interest rate. That can be a benefit when you want to preserve the rate, but it won’t help when your main goal is to replace the current rate with a different one.

A refinance may be the more relevant option when changing the rate is your priority.

Your loan term does not shorten

The servicer calculates the new payment using the time left on your current mortgage. Your required principal and interest payment decreases, but the scheduled maturity date generally stays the same.

You can still pay more than the new required amount if your loan allows additional principal payments. Doing so may reduce the balance faster.

Your cash is tied up in home equity

Once your servicer applies the principal payment, you generally can’t reverse it or withdraw the money from the mortgage. Home equity is less liquid than money in a bank account. Accessing your home equity later may require selling the home or qualifying for financing such as a cash-out refinance.

Consider your need for accessible savings before committing a substantial amount to the loan.

Not every loan or lender allows recasting

Recasting isn’t automatic, and servicers can set eligibility requirements for the loans they manage. Availability may depend on the loan type, principal reduction, payment history, and account status.

Confirm eligibility before making a payment specifically intended for a recast.

How soon can you recast a mortgage?

The timing has two parts: how long the mortgage must be active before it becomes eligible and how long the servicer needs to complete the request.

At Rocket Mortgage, a client must make at least two consecutive monthly payments before the loan becomes eligible for a recast. Once requested, the recast can take 45 – 60 days to complete. Continue making your current payment amount until the new payment is reflected on your statement.

Can you extend mortgage amortization?

A standard recast doesn’t extend the mortgage term. It recalculates the payment across the time already remaining.

Refinancing can replace the mortgage with a new loan that has a longer term.

A loan modification generally adds missed payments back into the balance and may also change the rate or term to bring the mortgage current. Loan modifications are hardship options, while a recast is elective and begins with a principal reduction.

Mortgage recast vs. principal payment

A principal curtailment is money applied directly to reduce the unpaid principal balance. The difference comes down to what happens after the principal reduction:

• Principal payment with a recast: The servicer lowers the required principal-and-interest payment. The remaining term and interest rate stay the same, and a fee may apply.
• Principal payment without a recast: The required payment generally stays the same. Continuing to pay that amount can help you pay off the mortgage sooner and reduce interest.

A recast provides more required-payment flexibility. Skipping the recast may fit someone who prioritizes a faster payoff over a lower monthly obligation.

How to qualify for mortgage recasting

Mortgage recasting requirements depend on the loan type, servicer, and status of the account. Confirm every requirement before sending the intended principal payment.

You can’t have a government-backed loan

FHA, VA, and USDA loans can’t be recast.^2,3 Policies on jumbo loans vary. Rocket Mortgage permits recasting on qualifying conforming loans associated with Fannie Mae or Freddie Mac. Rocket Mortgage doesn’t offer USDA loans.

You must meet minimum principal reduction standards

Servicers may require a fixed dollar amount, a percentage of the balance, or another minimum principal reduction.

Rocket Mortgage requires at least $10,000 to be applied to principal. The money doesn’t have to arrive as one lump-sum payment as long as the qualifying principal payments are made within a 12-month period.

You must satisfy equity requirements

Some servicers may consider how much equity you have when determining recast eligibility. There’s no single equity standard that applies to every servicer.

Rocket Mortgage doesn’t impose a separate equity requirement for an otherwise qualifying recast.

You must meet your servicer’s payment history requirements

A servicer may review the mortgage payment history and whether the account satisfies its recasting rules.

At Rocket Mortgage, the client must have made at least two consecutive monthly payments before the loan is eligible for recasting.

Mortgage recasting vs. refinancing

A mortgage recast changes the required payment on your existing loan after a principal reduction. Refinancing pays off the existing mortgage with a new loan, which can have a different interest rate, term, loan type, or lender.

Here are the primary differences:

• Loan structure: A recast keeps the existing mortgage. A refinance creates a new one.
• Interest rate: A recast keeps the existing rate. A refinance uses the rate available for the new loan.
• Term: A recast uses the remaining term. A refinance can establish a new term.
• Qualification: A recast typically doesn’t require new credit, income, asset, or appraisal qualification. A refinance requires lender approval.
• Costs: A recast generally involves a servicing fee. Refinancing has application and closing costs.
• Cash access: A recast requires you to put money into the mortgage. Certain refinance options may let you take cash out.

Review how refinancing works before comparing the processes. Refinancing also generally requires closing costs, while a recast typically involves a smaller servicing fee. Learn more about the potential cost to refinance.

When recasting may make sense

Recasting may align with your goals when you:

• Want to keep your current interest rate
• Have enough available cash for the required principal reduction
• Prefer a lower required payment
• Qualify under your servicer’s rules
• Don’t need a different loan type or term
• Don’t need to take cash out of your equity

Ask the servicer to estimate the payment reduction, fee, and effective date. That gives you concrete figures to compare with the amount you’ll apply to the principal.

When refinancing may make sense

Refinancing may fit your goals when you want a different interest rate, repayment term, loan type, lender, or cash-out option. Reviewing the available types of refinance can help you identify which options match your goal.

A rate-and-term refinance focuses on replacing the current rate, term, or both without taking cash out of the home.

Because refinancing requires new qualification and closing costs, consider the pros and cons of refinancing before choosing it over a recast.

How to calculate your mortgage recast

You can estimate a recast using four inputs:

• Estimated new principal balance: Current principal balance minus the qualifying principal payment
• Existing interest rate: The rate on the current mortgage
• Remaining term: The number of scheduled payments left
• Recasting fee: The amount charged by the servicer

The basic equation is:

Current balance − principal payment = estimated balance to reamortize

A mortgage recasting calculator can estimate the new principal-and-interest payment, but your servicer provides the official balance, payment, and effective date. Timing, payment application, and rounding may cause the official result to differ from your estimate.

Mortgage recast calculator example

Suppose Marion and Kelly take out a $350,000, 30-year fixed-rate loan at 6.75%. Their monthly principal and interest payment is $2,270.10.⁴

After 24 scheduled payments, their estimated principal balance is $342,279.87. They decide to apply $15,000 directly to the principal:

$342,279.87 − $15,000 = $327,279.87 estimated new balance

The servicer then reamortizes the estimated $327,279.87 balance at the existing 6.75% rate over the 28 years remaining. The estimated new principal and interest payment is $2,170.61.

In this example:

• Previous principal-and-interest payment: $2,270.10
• Estimated recast payment: $2,170.61
• Estimated monthly reduction: $99.49
• Principal payment: $15,000
• Rocket Mortgage recasting fee: $250
• Total immediate cash required: $15,250

Taxes and insurance aren’t included, so the total mortgage payment would be higher. The official figures may also differ based on the payment date, exact principal balance, and servicer calculations.

Should you recast your mortgage?

There’s no universal answer. A recast may give you a lower required payment while preserving the existing mortgage, but it also puts a substantial amount of cash into home equity.

Consider these questions:

• Do you want to keep your existing interest rate?
• Is a lower required payment more important than the earliest possible payoff?
• How much accessible savings will remain after the principal payment and fee?
• How much would the required payment decrease?
• Is the loan eligible, and how long will processing take?
• Could the principal reduction help you qualify to cancel PMI?
• Do you expect to sell or refinance soon?
• Would another use of the money better support your goals?

Contact your servicer for the exact requirements and payment estimate. You can also review the factors behind the question, “Should I refinance?,” before choosing between the two options.

FAQ

Here are direct answers to common questions about mortgage recasting.

Is mortgage recasting a good idea?

Mortgage recasting may be a good fit when you have enough cash for a qualifying principal reduction, want to keep your existing rate, and prefer a lower required payment. It may be less suitable when you need to preserve accessible savings, change the loan terms, or pay off the mortgage as quickly as possible.

What are the disadvantages of recasting?

A recast doesn’t change the interest rate or shorten the remaining loan term. It also requires a substantial principal payment, may involve a fee, and isn’t available for every loan. Once applied, the money becomes part of your home equity rather than accessible cash.

What is the fee to recast a mortgage?

The fee depends on the servicer. Rocket Mortgage charges $250 for a mortgage recast.

Confirm the fee before making the principal reduction because servicer policies can change.

Do you need a credit check or appraisal to recast?

A standard mortgage recast typically doesn’t require a new credit check or appraisal because it adjusts the payment schedule on the existing loan. Servicer policies may differ.

Can you recast your mortgage more than once?

Policies vary by servicer. Rocket Mortgage doesn’t limit the number of times a client can recast, but each request must meet the current recasting requirements.

How long does a mortgage recast take?

Processing times vary. A Rocket Mortgage recast can take 45 – 60 days to complete. Continue making your current payment amount until the new payment is reflected on your statement.

The bottom line: A mortgage recast could lower your payment

Mortgage recasting lowers the required principal-and-interest payment after you make a qualifying principal reduction. You keep the existing interest rate and remaining loan term, but eligibility, minimum amounts, fees, and timing depend on your servicer.

Contact your servicer before sending the payment. Confirm that your mortgage qualifies, how the funds must be submitted, what the fee will be, and when the new payment could begin.

If you decide a refinance is a better option for you than recasting, you can apply online with Rocket Mortgage to go over your options.
