If you are considering purchasing a higher-priced home in Montana, then a jumbo loan might be for you. This guide aims to help homebuyers understand jumbo loans in Montana, how they differ from conforming loans, and how to effectively use a jumbo loan calculator to help you estimate your potential monthly payment and total costs.

Key Points

Calculator Definitions

•   Jumbo loan: A jumbo loan is a mortgage exceeding the conforming loan limits set by the Federal Housing Finance Agency (FHFA). In Montana, the conforming loan limit in 2025 for a single-family home is $806,500.

•   Home price: This is the purchase price you’ve agreed upon with the home seller. It affects your estimated monthly mortgage payment, total interest paid, and overall loan cost.

•   Down payment: The down payment is the initial amount paid upfront. Jumbo loan requirements can be more strict, and you’ll typically need to put down at least 10% of the home price for this type of mortgage loan.

•   Loan term: The loan term is the duration to repay the mortgage, typically 30 or 15 years, though terms of 10 or 20 years are also available. A longer term lowers monthly payments but increases total interest paid while a shorter term saves on interest but increases monthly payments.

•   Interest rate: The interest rate is the cost of borrowing, expressed as a percentage of the loan amount.

•   Annual property tax: Property tax is levied by local governments on land and buildings. It is typically a percentage of the property’s assessed value, which may differ from its market value.
