Calculator Definitions

•   Jumbo loan: A jumbo mortgage loan is a home loan that exceeds the conforming loan limits set by the Federal Housing Finance Agency (FHFA). In Louisiana counties in 2025, the limit for a single-family home is $806,500. If you need a loan for more than this amount, you’re in the market for a jumbo loan.

•   Home price: The home price is the agreed-upon purchase price established between you and the home seller. This figure is essential for determining the size of your home loan and the overall cost of homeownership over time.

•   Down payment: The down payment is the initial amount the homebuyer contributes upfront, typically expressed as a percentage of the total purchase price. For jumbo loans, a down payment of at least 10% is generally required by lenders.

•   Loan term: The loan term is the length of time you have to repay the mortgage, from 10 to 30 years. A longer term lowers your monthly payment but increases the total interest paid over the life of the loan. A shorter term increases your monthly payment but reduces the total interest. Use the jumbo loan calculator to experiment with different loan term options to see what works for you.

•   Interest rate: The interest rate is the cost of borrowing money, expressed as a percentage of the total loan amount. Different types of mortgage loans have different rates. A lower interest rate reduces both your monthly payments and the total interest paid over the life of the loan, so you’ll want to shop around and compare offers from multiple lenders.

•   Annual property tax: Annual property tax is levied by local governments on land and buildings, typically expressed as a percentage of the property’s assessed value. In Louisiana, the effective property tax rate is 0.55%, one of the lower rates in the U.S.
