Homeownership can provide families with a lifetime of fun memories. For many working families, a mortgage makes homeownership more accessible. Mortgage refinancing is a familiar strategy. But here’s where familiarity can narrow your view of your finances. Mortgage recasting and lump-sum principal payment are two other viable techniques. Whether you’re in your “Forever Home” or need to create some additional flexibility in your budget, this article offers you a deeper dive into three mortgage adjustment tools.
Article Overview
Refinancing a mortgage means replacing your existing loan with a new one. The new loan could have a lower interest rate, shorter or longer term, or interest rate type (variable or fixed).
A mortgage recast recalculates monthly payments after a significant principal reduction, keeping the original loan term and interest rate.
A single, lump-sum principal payment is an additional payment made directly towards the loan principal, not the interest. It does not change your monthly payment.
Evaluating these mortgage strategies can help you feel more secure and in control as you align your family’s mortgage with your long‑term goals.

Mortgage Management Techniques to Consider
This article is going to be more helpful if you have a current mortgage and plan to stay in your home for at least the next 5-7 years. If you plan to relocate or move to a new home soon, these techniques are helpful to be aware of, but of less immediate value.
There are multiple mortgage strategies you can evaluate as your family’s needs change and interest rates adjust. Don’t let familiarity narrow your view of your finances.
And so, whether you’re a professional intent on staying in your home for the next 5-7 years, or you and your spouse have a family and want to spend the next 30 years in your Forever Home, here are three mortgage strategies you can evaluate right now.
Mortgage Recasting
What is mortgage recasting? Mortgage recasting is the process where you make a one-time, lump-sum payment towards your mortgage’s principal balance.
During mortgage recasting, your mortgage lender keeps your original mortgage term and interest rate the same. Many mortgage lenders charge a fee for mortgage recasting. It’s usually significantly less than the fees associated with refinancing, however.
Once you pay your mortgage recasting fee and follow the lender’s application process, your mortgage lender re-amortizes your loan.
When you re-amortize your loan, your mortgage lender recalculates a new monthly principal and interest payment based on the loan’s new, lower principal balance. This in turn lowers your monthly mortgage payments for the remainder of your mortgage.
The lower monthly payment due to re-amortization is a defining feature of mortgage recasting.
Additionally, mortgage recasting could result in a lower amount of total interest you pay over the remaining life of your mortgage compared to your original mortgage.
Now that you understand what mortgage recasting is, when might a homeowner like you want to evaluate mortgage recasting?
Recasting vs. Lump-Sum Principal Payment vs. Refinancing
A mortgage recast recalculates monthly payments after a significant principal reduction, keeping the original loan term and interest rate.
A recast lowers your monthly payment relative to your original loan. It also lowers the amount of interest you’ll pay over the remaining term of your mortgage.
Unlike refinancing your mortgage, recasting your mortgage doesn’t require an underwriting process. This allows you to avoid a credit check, the hassle of a home inspection, and the relatively high fees paired with the refinancing process.
Mortgage recasting makes sense when you want to keep your current mortgage rate, want to lower the total amount of mortgage interest payments you make over the life of the loan, and do not want to re-amortize your loan.
As you think about your own tax planning strategy, recasting your mortgage can dovetail well when you plan on taking the standard deduction. Meaning, your itemization strategy is not highly dependent on mortgage interest payment deductions. If you are itemizing, consider whether this approach aligns with your near-term tax planning goals.
Just don’t get lost focusing on only the tax elements to the detriment of your overall financial plan. Tax tail walking the dog…
Topics like mortgage recasting, like so many others in financial planning, intersect with the world of tax. Coordinate with a qualified tax professional on your specific situation.
Mortgage Refinancing
Refinancing a mortgage means replacing your existing loan with a new one.
This is helpful to homeowners like you when you want to secure a lower mortgage interest rate.
Refinancing also make sense when you want to change the term – or repayment period – of your mortgage. For example, if you have a 15-year mortgage, and want to lower your monthly mortgage payment by refinancing into a 30-year mortgage.
Refinancing from a 15-year mortgage to 30-year mortgage would provide you with financial flexibility to increase your personal cash flow to pursue other financial goals, like funding your retirement, paying down other debt, or saving more cash quicker for your emergency fund.
Homeowners who have an adjustable-rate mortgage and are looking to interest rate stability/payment predictability will refinance a mortgage to a fixed-rate.
Refinancing your mortgage can lower your monthly payments and reduce the total interest paid over the life of the loan.
When you refinance your mortgage, you reset the loan amortization schedule. Meaning if your current mortgage has 20 years left, and you refinance into a new 30-year mortgage, your final payoff date kicks out to the new loan’s 30-year term. That’s 10 more years of interest payments. It also means your new 30-year mortgage payments are composed more of interest than principal.
Single, Lump-Sum Principal Payment
A single, lump-sum principal payment is an additional payment made directly towards the loan principal, not the interest.
This strategy makes sense when you want to reduce your principal balance faster than if you followed your original payment schedule. This technique can save you money on mortgage interest and shorten the loan term.
As such, it doesn’t lower your monthly payment.
If you are considering a principal-only payment, your mortgage likely allows you to regularly pay down your principal balance.
Here’s a common misconception to consider. If you want to regularly pay down your mortgage with extra principal payments, it doesn’t have to be some grandiose figure. You can schedule additional payments that fit your budget.
Working with a financial planner to evaluate whether this approach, or using that cash elsewhere in your life, can provide you with better peace of mind.
Summary of Mortgage Management Techniques
As you evaluate each strategy, you’ll want your goals and personal situation to guide your review of each strategy.
If one of these approaches is going to strain other parts of your life, throw your well-crafted financial plan out of balance, then sticking with your current mortgage might just be the right choice.
As a summary, here’s an overview of the three mortgage management techniques we’ve discussed:
- Mortgage Recasting allows you to lower your monthly payment without changing your loan terms and have a lump sum available.
- Refinancing is helpful if you aim to secure a lower interest rate, change your loan term, or need cash out.
- Lump-sum principal-only payment lets you pay off your mortgage faster and reduce the total interest you pay without altering your monthly payment.
To show how these different techniques work, let’s explore a hypothetical mortgage.
Then, we can adjust the mortgage using each of mortgage recasting, mortgage refinancing, and a single, lump-sum principal only mortgage payment.
The figures used to create each scenario are hypothetical and simply meant for educational purposes. All the figures have also been rounded to the nearest whole dollar.
And with that, let’s dive in…
Illustrative Examples: Refinancing, Lump-Sum Principal Payment, and Recasting
For these illustrative examples, let’s consider an original mortgage with the following key details:
- Original Principal Balance: $450,000
- Annual Interest Rate: 5.750%
- Term (Years): 30
- First Payment Date: 9/1/2022
Illustrative Example: Refinancing
Now, for the hypothetical mortgage refinance, we assume the following on the new mortgage:
- New Annual Interest Rate: 4.500%
- Principal Balance: $434,881
- First Payment Date: 3/1/2025
The following table shows how mortgage refinancing lowers both the monthly payment as well as the total interest paid.
It also highlights that refinancing creates a new 30-year term for the mortgage.
Mortgage Refinance
Illustrative Example
This table illustrates the hypothetical Original and Refinanced mortgage metrics.
| Original Loan | After Refinance | Variance | |
|---|---|---|---|
| Principal Balance | $434,881 | $434,881 | – |
| Monthly Payment | $2,626 | $2,203 | ▼($423) |
| Total Principal Paid | $434,881 | $434,881 | – |
| Total Interest Paid | $431,724 | $358,369 | ▼($73,355) |
| Total Mortgage Payments | $866,604 | $793,249 | ▼($73,355) |
| Years Left in Mortgage | 27.5 | 30.0 | ▲2.5 |
| Payoff Date | Aug 2052 | Jan 2055 | ▲2.4 yrs |
1 The hypothetical original mortgage’s first payment occurred on September 1, 2022. The hypothetical mortgage refinance occurs on March 1, 2025.
2 Assumes mortgage refinancing costs are paid in cash, and not added to mortgage principal balance.
Illustrative Example: Lump-Sum Principal Payment
The following hypothetical lump-sum principal payment illustrates how the monthly mortgage payment is unchanged while the total interest paid is lower than the original mortgage. It also shows how making extra mortgage principal payments early can significantly reduce the total interest paid over the life of the mortgage.
Lastly, this example shows how much sooner the mortgage can be paid back after a significant principal reduction.
Quantifying how much quicker you can pay off your mortgage using a principal payment can help you with your other long-term planning.
One-Time Principal Payment
Illustrative Example
This table illustrates the hypothetical mortgage metrics after a one-time, $50,000 principal payment.
| Original Loan | After One-Time Principal Payment | Variance | |
|---|---|---|---|
| Principal Balance | $434,881 | $384,338 | ▼($50,542) |
| Monthly Payment | $2,626 | $2,626 | – |
| Total Principal Paid | $450,000 | $450,000 | – |
| Total Interest Paid | $495,387 | $345,180 | ▼($150,207) |
| Total Mortgage Payments | $945,387 | $795,180 | ▼($150,207) |
| Years Left in Mortgage | 27.5 | 23.7 | ▼(3.8) |
| Payoff Date | Aug 2052 | Apr 2046 | ▼(6.3 yrs) |
1 The original mortgage’s hypothetical first payment occurred on September 1, 2022. The hypothetical one-time principal payment occurs on March 1, 2025.
2 Assumes hypothetical mortgage refinancing costs are paid in cash, and not added to mortgage principal balance.

If you’re comfortably enjoying your forever home and 2.5% mortgage, refinancing likely isn’t something you need to worry about.
However, if your mortgage interest rate is between ~6.0% and ~7.5%, it’s worth looking deeper into your options.
As a homeowner, you value making smart financial decisions that support your goals. As a long-term thinker, you want to understand how your decisions will look over a span of decades rather than months or years. Your mortgage interest rate affects your family’s annual spending, tax planning, and long-term planning.
When you understand what mortgage refinancing is, and its alternatives, you can understand whether it aligns with your long-term goals. You can be better prepared for when mortgage rates adjust in your favor.
Hopefully you found this review of mortgage refinancing, mortgage recasting, and one-time lump sum principal payments educational.
