Santa Barbara down payment vs rate buydown example

You have an extra $50,000. Should it go toward a bigger down payment, or toward buying down your interest rate? Here is a Santa Barbara example, with real math.

Extra $50K: put it down or buy down the rate?

The setup

A $1,500,000 home with 20% down ($300,000) means a $1,200,000 loan. At 7.875%, the principal and interest payment is about $8,701 per month.

The setup: $1,500,000 home, 20% down, $1,200,000 loan at 7.875%

Option A: put the $50K toward the down payment

Your loan drops to $1,150,000. The payment becomes about $8,338 per month. That saves about $363 per month.

Option A: put the $50K toward the down payment

Option B: use the $50K to buy down the rate

In this example the $50K buys the rate down to about 6.83%. The payment becomes about $7,847 per month. That saves about $854 per month.

Option B: use the $50K to buy down the rate

The break-even

$50,000 divided by $854 is about 59 months, or roughly 5 years. If you expect to keep the loan longer than that, the buydown comes out ahead. If you may sell or refinance sooner, the larger down payment may fit better.

The break-even: about 59 months

Side by side comparison

Takeaways

  • Run both numbers before you decide. The best answer depends on how long you will hold the loan.
  • Rates, points pricing and loan terms vary by lender and borrower. Ask for a written quote on each option.

Next steps

Remember: run both numbers
