How Much Does a Mortgage Rate Buydown Cost?

A mortgage rate buydown is a financing strategy that reduces the interest rate on a home loan, either temporarily or for its entire duration. This technique can make monthly mortgage payments more manageable, especially in higher interest rate environments. By paying an upfront fee, borrowers can secure a lower rate, potentially leading to significant savings over time.

Calculating Buydown Costs

The cost of a mortgage rate buydown is primarily calculated using “points,” which are fees paid directly to the lender at closing. One point is equivalent to one percent of the total loan amount. For instance, on a $350,000 mortgage, one point would cost $3,500. These points are prepaid interest paid upfront to secure a lower interest rate.

The reduction in the interest rate per point varies among lenders, loan types, and market conditions, typically ranging from 0.125% to 0.25% per point. For example, if a lender charges one point costing $3,000 on a $300,000 loan, the interest rate might drop by 0.25%. This means a 7% interest rate could become 6.75%. To achieve a larger rate reduction, a borrower would need to purchase more points.

For a $400,000 mortgage, two points would cost $8,000 (2% of $400,000). If each point reduces the rate by 0.25%, then two points would lower the interest rate by 0.50%. This would effectively reduce the monthly payment, leading to savings over the loan’s life. Calculating the break-even point is important to determine how long it takes for the monthly savings to offset the upfront cost of the points. This is done by dividing the total cost of points by the monthly savings.

Key Factors Affecting Buydown Expenses

Several elements influence the total expense associated with a mortgage rate buydown. The total loan amount is a significant factor, as points are calculated as a percentage of the principal. A larger loan means a higher dollar cost for each point purchased. For example, one point on a $200,000 loan costs $2,000, while on a $500,000 loan, it costs $5,000.

The desired reduction in the interest rate also directly impacts the expense. Achieving a more substantial rate decrease typically requires purchasing more points, thereby increasing the upfront cost. Lenders determine how many points are needed for a specific rate reduction, and this can vary. Some lenders may offer fractions of a point, while others might allow up to three points.

Prevailing market interest rates play a role, influencing the cost-effectiveness and availability of buydowns. In periods of higher interest rates, buydowns can become a more attractive option, though the cost to achieve a meaningful reduction might also be higher. Lender policies and fees also contribute to the overall expense, as each lender sets its own framework for mortgage points and their corresponding rate reductions.

Temporary and Permanent Buydowns

Mortgage rate buydowns generally come in two structures: temporary and permanent. Temporary buydowns reduce the interest rate for a specific initial period, typically one to three years, before the rate reverts to the original, higher rate. Common types include the 2-1 buydown and the 3-2-1 buydown. With a 2-1 buydown, the interest rate is reduced by 2% in the first year and 1% in the second year, returning to the full rate in the third year. Similarly, a 3-2-1 buydown reduces the rate by 3% in the first year, 2% in the second, and 1% in the third.

The cost for temporary buydowns is calculated as the difference in interest payments over the temporary reduction period. This amount is typically paid upfront into an escrow account at closing, and the funds from this account subsidize the borrower’s payments during the reduced-rate period. While these offer lower initial monthly payments, borrowers must qualify for the mortgage at the full, original interest rate.

In contrast, permanent buydowns, also known as discount points, involve paying points upfront to secure a lower interest rate for the entire life of the loan. This type of buydown provides long-term savings on interest, benefiting borrowers who plan to remain in their home for many years.

Who Funds a Rate Buydown

The financial responsibility for a rate buydown can fall on different parties, influencing the borrower’s out-of-pocket expenses. In a borrower-paid buydown, the homebuyer pays the points directly, typically as part of their closing costs. This option suits buyers with sufficient liquid assets. The decision to pay for points often depends on how long the buyer expects to stay in the home, as savings accrue over time.

Alternatively, a home seller can fund a buydown as a concession to the buyer. This is a common negotiation tactic where the seller agrees to pay for some or all buydown points. These seller contributions are part of the purchase agreement and can significantly reduce the buyer’s upfront cash requirement. Limits may apply to the percentage of the home’s price that sellers can contribute, depending on the loan type.

Home builders also frequently offer to pay buydown costs as an incentive, particularly for new construction homes. Builders use buydowns to attract buyers and make new homes more affordable, often working with a preferred lender to facilitate these offers.
