Mortgage Recasting: What It Is & How It Works

Thinking about lowering your monthly mortgage payment? If you have a lump sum available to put toward your home loan, a mortgage recast could help you reduce your monthly principal & interest (P&I) payments while keeping your current interest rate.

What Is a Mortgage Recast?

A mortgage recast happens when you make a large, one-time payment toward your loan balance, and we recalculate your payment schedule based on your new, lower balance. Think of it as hitting the "refresh" button on your monthly payment—without changing your interest rate or loan term.

Here's what stays the same:

• Your interest rate
• Your loan's end date and term

Here's what changes:

• Your loan balance goes down by the lump sum amount
• Your monthly P&I payment decreases
• You will pay less total interest over the life of your loan

How Does Mortgage Recasting Work?

The process is straightforward. When you recast your mortgage, your lump sum payment goes directly toward reducing your principal balance. We then re-amortize your loan—essentially creating a new payment schedule that spreads your smaller remaining balance over the time you have left on your loan.

Because you're paying interest on a smaller balance, your monthly payment goes down. And since you've eliminated a chunk of principal, you'll save on interest charges over time.

When Does Mortgage Recasting Make Sense?

Many homeowners consider recasting when they come into a significant amount of money and want to put it to work reducing their monthly obligations. Consider recasting if:

• You have ample savings or are expecting a windfall such as a bonus or inheritance
• You’d like more flexibility in your monthly budget
• You want to keep your current rate and term
• You do not have high-interest debt, like a credit card balance, to pay down first

Steps to Recast Your Mortgage at CSB

Ready to explore recasting? Here's how the process works:

Step 1: Reach Out to Us to Confirm Your Eligibility

Contact our Loan Servicing Department to confirm that recasting is available for your loan type. While we offer recasting on many conventional loans, not all loan types are eligible. 

We'll review your loan to make sure you meet the requirements, which may include having a certain loan type and a minimum lump sum amount ($10,000 or more). 

Step 2: Make Your Payment and Sign Required Paperwork

When you're ready to move forward, you'll sign a loan modification document and make your lump sum payment along with any applicable fees. The loan modification document will include your new payment due after the recast is completed. 

Step 3: Enjoy Your Lower Payment!

Your new, lower monthly payment will take effect. You'll continue making payments as usual—just at the reduced amount.

Benefits of Mortgage Recasting

Lower Monthly Payments

Your monthly P&I payment decreases immediately, giving you more breathing room in your budget each month.

Save on Interest Over Time

While your interest rate stays the same, you'll pay less total interest because your lump sum payment won't accumulate interest charges going forward. Every dollar you pay down in a lump sum now is a dollar that won't cost you interest later.

No Credit Check Required

Your credit score won't factor into the recasting decision. As long as you meet our recasting criteria, you're good to go—even if your credit score has changed since you first got your mortgage.

Things to Consider Before Recasting

Cost

There's a $250 processing fee¹ for recasting. Most homeowners recoup this cost quickly through their monthly savings.

Eligibility Requirements

Recasting is available on many conventional loans, but eligibility depends on your specific loan type. Additionally, we require a minimum lump sum payment amount of $10,000 or more. The best way to find out if you're eligible is to connect with Loan Servicing.

Your Financial Goals and Timeline

Before you recast, think about your bigger financial picture:

• How long will you keep this home? If you're planning to sell soon, recasting may not give you enough time to benefit from the lower payments.
• What else could you do with this money? If you have a very low mortgage rate and other higher-interest debt, or if investment opportunities could yield better returns, those might be smarter uses for your lump sum.
• Can you comfortably afford your current payment? If your current payment is manageable and you have a great interest rate, investing the money elsewhere might make more financial sense.

Alternatives to Mortgage Recasting

Recasting isn't the only way to manage your mortgage more effectively. Here are a couple of other strategies worth considering:

Making Additional Payments Toward the Principal

You can always make extra payments toward your principal without recasting. This approach offers flexibility—you can contribute extra money whenever your budget allows, whether that's a few hundred dollars each month or a lump sum payment.

The key difference: these additional payments won't lower your required monthly payment. Instead, they'll help you pay off your mortgage faster and reduce your total interest paid over time.

Curious how much you could save by making extra payments? Try our early loan payoff calculator or lump sum debt payoff calculator to see how additional payments can accelerate your payoff timeline and reduce your interest costs.

Refinancing

Refinancing means replacing your current mortgage with a brand-new loan—complete with a new interest rate and potentially a new term length.

Refinancing typically costs more upfront than recasting (usually 2-5% of your loan amount in closing costs). However, if current mortgage rates are significantly lower than your existing rate, refinancing could save you more money in the long run, even without making a lump sum payment. You might also refinance to shorten your loan term, switch from an adjustable to a fixed rate, or tap into your home's equity.

Which Option Is Right for You?

When deciding between recasting, refinancing, or making additional payments, ask yourself:

• How long do I plan to keep this mortgage?
• What are the upfront costs, and how long will it take to break even?
• How much will I save over time?
• Do I have a lump sum available, and is this the best use of it?
• What are my primary goals—lower monthly payments, paying off my loan faster, or reducing my interest rate?

As a general guide:

• Making additional payments works well if you have a low interest rate and want the flexibility to pay down principal as your budget allows, helping you pay off your loan early and become mortgage-free sooner.
• Recasting works well if you have a lump sum to invest, and want to reduce your required monthly payment.
• Refinancing works well if current interest rates are lower than your rate, or if you want to change your loan term or access your home equity.
