• Home price: This is the home purchase price that you and the seller both agree upon. This final price may differ from both the initial listing price and the amount of your first offer.

• Down payment: This is the amount of money that you pay upfront when you get your loan. The amount is often expressed as a percentage of your total purchase price. Most buyers put down between 3% and 20% of the home’s value for a conventional loan. Down payment assistance programs may be available in Connecticut to help you cover this cost.

• Loan term: This is the length of time you have to repay your home loan. Terms are usually structured as either 15 or 30 years. The shorter term can significantly lower the total interest you’ll pay over the loan’s duration, but it typically comes with higher monthly payments. Carefully consider your financial situation and goals when you’re choosing your mortgage term.

• Interest rate: This is the cost of borrowing money and is typically expressed as a percentage of the total loan amount. The rates you’ll be offered will depend on market conditions and on potential lenders’ assessment of your financial situation and creditworthiness.

• Annual property tax: Local governments levy these taxes on both land and buildings within their jurisdiction. These taxes are typically expressed as a percentage of the property’s assessed value. Find your property tax rate by searching online for the town, county, or ZIP code where the property is located and “effective property tax rate.”

• Monthly payment: This is the amount that you’ll be charged each month toward the principal loan amount and accruing interest. Usually, it will also include payments toward your property tax as well, and may also include money for homeowners insurance and homeowners association (HOA) fees or private mortgage insurance (PMI) if your down payment was less than 20%.

• Total interest paid: This is the cumulative amount of interest that you will be required to pay over the entire duration of your loan. This total can be substantial, especially for longer loan terms. Choosing a larger down payment or a shorter loan term can reduce the total interest you pay over time.

• Total loan cost: This is the entire amount of money you will repay for the loan, including both the principal and the accumulated interest over the loan’s term. Elements like the length of your loan term, your interest rate, and your down payment amount play into the total cost of your loan.
