Why waiting for lower mortgage rates could backfire — or pay off

There’s a familiar argument in real estate: buy the house now, and refinance when mortgage rates come down.

There’s another one that’s become increasingly popular: wait until rates drop, because buying at today’s rates makes no financial sense.

I think both arguments oversimplify a much more complicated decision.

Waiting for lower rates could save you a substantial amount of money. It could also mean losing negotiating power, facing higher home prices, or spending another year renting without improving your financial position.

And there’s a third possibility that doesn’t get discussed enough: mortgage rates might not come down anytime soon.

For buyers in Boise, Meridian, Kuna, and the surrounding Treasure Valley, the right decision depends on much more than predicting the direction of interest rates.

Mortgage rates aren’t expected to fall significantly anytime soon

As of October 15, 2026, Freddie Mac reported the average 30-year fixed mortgage rate at 7.40%, unchanged from the week before. A year earlier, it was 6.27%.

That pause came after seven straight weekly increases, and it leaves rates at their highest level since November 2023. Mortgage rates closely follow the 10-year Treasury yield, which has been hovering above 5% amid inflation worries and a broad bond-market selloff.

The latest forecasts aren’t particularly encouraging for buyers expecting quick relief. Here’s Fannie Mae’s October 2026 housing outlook:

The Mortgage Bankers Association is in roughly the same place, projecting about 7.3% for the fourth quarter and rates above 7% through 2027. Not every analyst is this pessimistic, but the two biggest housing-finance forecasters agree that relief isn’t imminent.

These are national averages for borrowers with strong credit and 20% down, not quotes. Your actual rate depends on your credit, down payment, and loan type.

What’s particularly telling is how fast expectations moved. In its previous forecast, Fannie Mae expected rates of 6.8% this quarter and 6.7% in 2027. One month later, both numbers jumped by about three-quarters of a point.

If professional economists can change their projections that quickly, buyers should be cautious about building a major financial decision around any specific rate prediction, whether it points up or down.

What the Treasure Valley market actually looks like

High rates haven’t stalled the local market. Here’s where Ada County stood in September 2026, based on local MLS figures:

Two things stand out. Prices are still rising modestly. And with roughly 2.4 months of supply, Ada County is still below the 4 to 6 months usually considered a balanced market. Canyon County remains the more affordable option, with a September median of about $443,500.

Worth noting: September’s closings mostly reflect contracts written in August, when rates were in the mid-6% range. October and November data will show how buyers respond to rates above 7%.

Why waiting for lower rates could backfire

1. Lower rates could bring more buyers back into the market

Affordability is the biggest challenge in the housing market right now. Higher rates have reduced purchasing power and pushed some buyers to the sidelines.

But what happens if rates fall substantially? Some of those buyers may return.

We’ve already seen a preview locally. Ada County single-family sales were up 20.5% year over year in June 2026, when rates were still in the 6% range, as buyers who had been waiting started moving again.

More buyers competing for the same homes can mean stronger offers, fewer seller concessions, and upward pressure on prices. That doesn’t mean lower rates automatically push prices up. Inventory, employment, and incomes still matter. But if you’re waiting for cheaper financing, you may be competing with plenty of other households running the same strategy.

2. Today’s buyers may have some negotiating room

The overall numbers say Ada County is still seller-leaning. But averages hide a lot. Some homes, especially those that are overpriced or need work, sit well past the average and see price cuts. Many builders are offering rate buydowns and closing-cost credits to move finished inventory.

For a qualified buyer, that can create opportunities.

A seller whose home has been on the market for 75 days, nearly twice the county average, may be open to an offer below asking or a credit toward closing costs.

A builder with completed homes may offer a rate buydown that meaningfully lowers your payment, at least for the first few years. Make sure you know what the payment will be once any temporary buydown ends. (Here’s more on how builder incentives are changing the math in Kuna, Nampa and Meridian.)

Those opportunities may be harder to find if buyer demand picks up.

The question isn’t simply whether rates are high. It’s whether the price and terms available today make up for the higher financing cost.

3. Waiting doesn’t guarantee a better deal

Here’s an illustration. Say you’re looking at a $500,000 home in Boise with 10% down.

In the first waiting scenario, a full one-point rate drop saves only about $129 a month, because the higher price ate most of the benefit. You’d also need $2,500 more for the down payment.

In the second, waiting paid off without any help from rates.

Both outcomes are possible. That’s why I think buyers should pay as much attention to local inventory, seller motivation, and comparable sales as they do to mortgage rates. You can plug in your own numbers with my mortgage calculator.

These are simplified estimates for illustration only. They exclude property taxes, homeowners insurance, mortgage insurance, and HOA dues, and assume a 30-year fixed loan. Talk to a lender for numbers specific to you.

Why waiting could actually be the smarter decision

Here’s the part that doesn’t get emphasized enough in real estate marketing.

There are legitimate reasons not to buy a house right now.

1. You might be stretching your budget too far

Just because a lender approves you for a $550,000 home doesn’t mean you should buy one.

A mortgage payment needs to fit comfortably alongside retirement contributions, emergency savings, childcare, transportation, and the rest of your household expenses. My home affordability calculator can help you find that line.

If today’s payment leaves you financially uncomfortable, buying on the assumption that you’ll refinance later is a gamble. Refinancing only works if rates actually fall, if your credit and income still qualify, and if your home has held its value. It also comes with closing costs, often thousands of dollars. Buy a payment you can live with at today’s rate, and treat any future refinance as a bonus, not a plan.

2. You might not stay long enough

Buying and selling a home both carry real costs: closing costs, agent commissions, moving, and furnishing. If there’s a good chance you’ll relocate within two or three years for work or family, those costs can wipe out any equity you build. Renting a bit longer may be the cheaper choice. My rent vs. buy calculator shows the break-even year on a specific house.

3. Your savings need more runway

A down payment isn’t the only cash you need. Plan for closing costs, inspection and appraisal fees, and a cushion for the repairs every house eventually needs. Draining your savings to close leaves you exposed the first time the water heater fails. Spending another six to twelve months building reserves can put you in a much stronger position.

4. Your credit or income is about to improve

If you’re a few months from a raise, paying off a car loan, or pushing your credit score into a higher tier, waiting can earn you a better rate regardless of where the market goes. That’s a rate improvement you control.

The bottom line

The right question isn’t “Will rates go down?” Nobody can answer that reliably, as this month’s forecast revisions showed.

Better questions are:

• Can I comfortably afford this payment at today’s rate?
• Do I plan to stay at least five years?
• Do this home’s price and terms make sense compared with recent sales nearby?
• Will I have healthy savings left after closing?

If you can answer yes to all four, waiting for a lower rate may cost you more than it saves. If not, waiting is a perfectly reasonable decision, and anyone pressuring you otherwise isn’t looking out for you. (For more on that side of it, read when you shouldn’t buy a house in Boise.)

If you’re weighing this in Boise, Meridian, or anywhere in the Treasure Valley, I’m happy to walk through the numbers on a specific home or neighborhood with you, with no pressure either way.
