Mortgage Interest Rates and Buy Downs: How to Lower Your Monthly Payment.
Navigating the housing market can feel like a complex math problem, especially when it comes to the “big question”: mortgage interest rates. While most buyers focus solely on finding the lowest number, the experts at loanDepot emphasize that the interest rate is just one piece of a much larger financial puzzle.
In a recent “Home School” session, the team broke down the fundamentals of interest rates, the factors that drive them, and the strategies you can use to lower your monthly payment.
Key Takeaways
- Interest rates are just one part of the financial puzzle; the best loan depends on your specific goals like monthly cash flow or long-term savings.
- Personal factors like your credit score and loan type, alongside global economic trends, determine your specific mortgage rate.
- Permanent buy downs allow you to lower your rate for the life of the loan by paying discount points upfront.
- Temporary buy downs (like 2-1 or 1-0) offer lower payments in the initial years, often funded by seller concessions.
The Interest Rate Myth: Is Lower Always Better?
An interest rate is simply the cost of borrowing money. However, a lower rate does not automatically equate to a better loan for your specific situation.
- 15-Year vs. 30-Year Terms: You might see a lower rate on a 15-year fixed mortgage, but because the payoff period is compressed, your monthly payment will be significantly higher than a 30-year mortgage. If your goal is monthly cash flow, the 30-year option might actually be the superior choice.
- The Cost of Points: Some lenders offer ultra-low rates that require you to pay discount points upfront. loanDepot advises calculating whether that upfront cost depletes your cash reserves too much for your comfort level.
What Drives Your Mortgage Rate?
Your rate is influenced by both personal and global factors:
- Credit Score: A strong credit profile is one of the most effective ways to earn a lower rate.
- Loan Type: Whether you choose FHA, VA, or Conventional financing, each product has a unique rate structure.
- The Economy: Rates change daily—and sometimes hourly—based on moves by the Federal Reserve, the bond market, and global financial events.
Strategic Financing: Understanding Buy Downs
If you aren’t satisfied with the current market rate, you have options to change it. This is known as a buy down—paying an upfront fee to secure a lower rate.
Permanent Buy Downs
By paying discount points, you lower the interest rate for the entire life of the loan. To see if this makes sense, loanDepot suggests calculating your recoup period.
- The Math: Divide the upfront cost of the point by the monthly savings. For example, if it costs $1,000 to save $25 a month, it will take 40 months to “recoup” that cost. If you plan to stay in the home longer than 40 months, it’s a win.
Temporary Buy Downs (1-0 and 2-1)
These are popular strategies to ease into a mortgage payment, especially if the seller is willing to pay for the buy down as an incentive.
- 2-1 Buy Down: Your rate is 2% lower in the first year and 1% lower in the second year before returning to the permanent rate in year three.
- 1-0 Buy Down: Your rate is 1% lower for the first year only.

Transcript:Mortgage Interest Rates and Buy Downs: How to Lower Your Monthly Payment.
In this “Home School” session, loanDepot provides a comprehensive guide to understanding mortgage interest rates, debunking common myths, and explaining how borrowers can strategically manage their monthly payments.
The Fundamentals of Interest Rates
- Definition: An interest rate is the cost of borrowing money from a lender. Your monthly payment is determined by the rate, the loan term, and the total amount borrowed [00:16].
- The “Lowest Rate” Myth: A lower interest rate does not always mean a better deal. For instance, a 15-year mortgage often has a lower rate than a 30-year mortgage, but the monthly payment will be higher because the debt is repaid over a shorter period [00:30].
- Factors Influencing Your Rate: Key drivers include your credit score, the specific type of loan product, and broader economic factors like the Federal Reserve, the bond market, and global events [01:45].
Strategic Options: Buy Downs
A “buy down” is when you pay an upfront fee to lower your interest rate, which can be done in two ways [03:12]:
- Permanent Buy Downs (Discount Points):
- Lowers the rate for the entire life of the loan.
- Recoup Period: To decide if this is worth it, calculate the “recoup period” by dividing the upfront cost of the point by the monthly savings. If you plan to stay in the home longer than this period, it may be a beneficial move [03:32].
- Temporary Buy Downs (e.g., 1-0 or 2-1):
- 1-0 Buy Down: The rate is 1% lower in the first year and returns to the permanent rate in year two [05:32].
- 2-1 Buy Down: The rate is 2% lower in year one, 1% lower in year two, and returns to the permanent rate in year three [05:54].
- Use Cases: These are ideal for buyers who expect to move in a few years or when a seller offers to pay for the buy down as an incentive [06:14].
The video concludes by emphasizing that interest rates change daily and that there is no “perfect” time to buy. Instead, borrowers should focus on their unique financial situation and work with a consultant to find the best fit [02:15].
