Purchasing Power and Mortgage Rates: Why Every Percent Matters

Last week’s Fed meeting drew plenty of attention, with many hoping a rate cut would deliver an immediate drop in mortgage rates. Instead, the Fed lowered its benchmark rate by 0.25%, and mortgage rates barely budged. That’s because mortgage rates don’t move directly with the Fed’s short-term rate—they’re influenced by the 10-year Treasury yield and the outlook for jobs and inflation.

In fact, the recent cut was already baked into market expectations. When stronger-than-anticipated data was released afterward, mortgage rates ticked up.

The silver lining? Even without a fresh drop, mortgage rates remain close to their lowest point in 11 months, which is fueling a wave of activity among buyers and homeowners.

Why Mortgage Rates Matter Right Now

Lower rates are prompting more people to act—whether that’s refinancing or stepping into the housing market.

1. Nationally: Mortgage applications surged nearly 30% last week. Refinances made up the bulk of the increase, but purchase applications also climbed 12% week-over-week and are up 20% year-over-year.

2. Locally: Ada County home sales in August rose 14.7% compared to last year, a clear sign of renewed buyer momentum in the Boise market.

    

What a 1% Dip Looks Like

It may not sound like much, but even a single percentage point lower on mortgage rates can change the math in a big way. Take this example:

1. Purchase price: $600,000

2. Down payment (20%): $120,000

3. Loan amount: $480,000

At a 7% rate, the monthly principal & interest payment is about $3,195.

At a 6% rate, it drops to about $2,878.

That translates into:

1. $317/month saved

2. $3,800/year saved

3. More than $100,000 in interest saved over the life of the loan

Or, if you prefer to look at buying power:

1. At 7%, a $3,200/month budget buys around $600K.

2. At 6%, the same budget stretches to about $665K.

    

Looking Ahead

The Fed has projected two more rate cuts this year, but history tells us not to assume mortgage rates will automatically follow. Last year, the first cuts were met with higher mortgage rates instead. With fresh economic data and Fed speeches on the horizon, there’s still plenty of room for movement before year’s end.

For now, the opportunity is clear: mortgage rates remain near 11-month lows, buyers are jumping back in, and even a modest change in rates makes a lasting difference in affordability.
