• Home price: The home price is the agreed-upon purchase price between the buyer and seller. It is crucial for determining the size of your home loan and the overall affordability of the property.

• Loan term: The loan term is the duration over which you repay the mortgage, typically 15 or 30 years. A longer term lowers monthly payments but increases total interest paid. A shorter term raises monthly payments but reduces total interest.
• Interest rate: The interest rate is the cost of borrowing, expressed as a percentage of the loan amount. It can be fixed or variable. Factors influencing the rate include credit history, market trends, and the type of mortgage loan.

How to Use the New Hampshire Jumbo Loan Calculator
The New Hampshire jumbo loan calculator helps estimate the costs of a jumbo loan. Here’s a step-by-step guide on how to use the calculator.
Step 1: Enter Your Home Price
Type in the final agreed-upon home price from your contract.
Step 2: Add a Down Payment Amount
Specify the amount you plan to put down upfront. A down payment of at least 10% is generally required for jumbo loans. A down payment calculator can help you decide on your number.
Step 3: Choose a Loan Term
Select the loan term that aligns with your financial goals. Common terms are 15 and 30 years, but the calculator allows you to select a term as low as 10 years. A longer term lowers monthly payments but increases total interest paid. A shorter term raises monthly payments but reduces total interest.
Step 4: Enter an Interest Rate
Input the anticipated interest rate to the second or third decimal point. Adjusting the interest rate helps you see how it impacts your monthly payments and total loan costs.
Step 5: Enter Your Annual Property Tax
Input your annual property tax rate, not the dollar value. In New Hampshire, the average effective property tax rate is 1.89%.
What Are Jumbo Loans and Conforming Loan Limits?
A jumbo loan is a mortgage that exceeds the conforming loan limits set by the Federal Housing Finance Agency. These limits are typically $806,500 for a single-family home, but they can be higher in high-cost areas. In most New Hampshire counties in 2025, the conforming loan limit is $806,500, while in Rockingham and Strafford counties, it is $914,250. If your loan amount surpasses these limits, you will need a jumbo loan.
When comparing jumbo loans vs. conventional loans, jumbo loans often have stricter qualification criteria, such as higher credit scores and significant cash reserves. Despite these requirements, jumbo loans offer flexibility and can be a viable option for financing expensive properties.
Using a jumbo loan mortgage calculator offers several advantages. First, it helps you budget effectively by providing a clear estimate of your potential monthly mortgage payments, which includes principal, interest, and property tax.
Second, the calculator allows you to see how small changes in interest rates can significantly affect your monthly payments and total loan costs. And finally, it shows you how down payments affect your loan, with higher down payments lowering both the loan amount and the monthly payment.
How to Use the Jumbo Loan Calculator to Compare Scenarios
Use the jumbo loan calculator to compare different loan scenarios and meet your financial goals. Here’s how you can use it:
• Adjust the home price to see how it affects affordability.
• Explore various down payment amounts to see their impact on monthly payments.
• Consider different loan terms to understand the trade-offs between monthly payments and total interest paid.
• Explore different interest rates to find the best option.
• Understand the impact of property tax rates on your monthly payment.

Deciding How Much House You Can Afford in New Hampshire
Determining how much house you can afford in New Hampshire involves several key factors. Home prices vary, and lenders generally recommend that your mortgage payment should not exceed 28% of your gross monthly income. For a $1 million home, assuming a 10% down payment ($100,000) on a 30-year mortgage at 6.75%, the monthly mortgage payment would be approximately $5,837, excluding property taxes and insurance. To make this payment, lenders recommend an income of $250,000 per year.
Factoring in debts is also important, as lenders advise that total debt payments should stay within 36% of your gross monthly income. In the example above, if your debts exceed about $1,600 a month — think about student loans, credit cards, and car payments — the income needed for a $900,000 mortgage would be higher.
Mortgage preapproval can clarify your maximum mortgage, simplifying the homebuying process. Though, only you can say what a comfortable budget is, based on your assets, lifestyle, and financial goals.
The main components of a jumbo loan payment include the principal amount borrowed and the interest charged on that principal. Other components include property tax — which is included in our calculator — as well as homeowners insurance and homeowners association (HOA) fees. Knowing how these expenses factor in gives you a clearer view of your overall financial commitment and helps you prepare for the true costs of homeownership.

Cost of Living in New Hampshire
The cost of living in your area will significantly affect how much you can afford. Higher cost of living areas typically have higher average home prices, as well as increased costs for utilities, home maintenance, transportation, and other necessities. Even if you think your mortgage payment will be manageable, consider the broader financial picture.
According to MERIC, the cost of living in New Hampshire is 111.4, which is about 11% higher than the national average of 100. Housing and utilities are 17% higher than the national average, and transportation is almost 3% higher.
You can use a home affordability calculator to factor in all your expenses and arrive at a realistic budget for your new home.
Tips on Reducing Your Jumbo Loan Payment
Reducing your jumbo loan payment can make homeownership more manageable. Here are some strategies to consider:
• Choose a longer loan term, such as a 30-year mortgage, to lower monthly payments.
• Shop for a lower interest rate to reduce monthly payments and total interest paid.
• Consider an adjustable-rate mortgage (ARM) for possibly a lower initial interest rate, but be prepared for potential rate increases.
• Make a larger down payment to reduce the loan-to-value ratio and improve loan terms.
• Recast your mortgage with a large lump-sum payment to lower your monthly payments.
• Modify your loan during financial hardship to make payments more affordable.
• Shop around for a more favorable homeowners insurance rate.

When considering a jumbo loan in New Hampshire, a jumbo loan calculator helps you estimate monthly payments, the total interest paid, and the overall cost associated with financing a more expensive home.

How much is a $900,000 mortgage payment for 30 years?
To estimate the monthly payment for a $900,000 mortgage over 30 years, use a jumbo loan calculator. Assuming a fixed interest rate of 6.00%, the estimated monthly payment would be approximately $5,390, including principal and interest, but not property taxes or insurance.
Is $900,000 a jumbo loan?
Yes, a $900,000 mortgage is generally considered a jumbo loan because it exceeds the conforming loan limits set by the Federal Housing Finance Agency. In most areas, the limit is $806,500, but it can be higher in certain high-cost areas. Jumbo loans have stricter qualification requirements but can offer competitive interest rates and flexible terms.
Do you need 20% for a jumbo loan?
While a 20% down payment is ideal for a jumbo loan, it is not always required. Some lenders accept down payments as low as 10%, but this can lead to higher interest rates and additional costs. Use a down payment calculator to understand the impact of different down payment amounts on your monthly mortgage payments and overall financial health.
What credit score is needed for a jumbo loan?
To qualify for a jumbo loan, lenders typically require a higher credit score, often around 700, with some setting the bar at 740 or above. A strong credit score demonstrates responsible debt management, which is crucial for larger loan amounts. Higher scores can lead to more favorable loan terms, such as lower interest rates and reduced closing costs. Check your credit score and take steps to build it before applying for a jumbo loan.
