6.7%to6.8%

Where Fannie Mae expects the 30-year fixed to sit, quarter by quarter, through the end of 2027. Today's actual rate: 6.95% (as of Sep 17, 2026).

Cut odds vanish

As of Sep 16, markets see zero chance of a Fed rate cut on Oct 28.

Instead: 0% odds rates hold steady · 100% odds of a hike

When cut odds disappear like this, mortgage rates don't get easier — they tend to hold or climb. That makes it very unlikely the 6.7%–6.8% forecast above comes down soon, and a real chance it moves higher instead.

Why your rate is what it is

Your mortgage rate is two numbers stacked on top of each other.

Almost nobody explains this, and it's the reason rates can move differently than the headlines suggest. Your rate is what investors charge the US government, plus everything it costs to turn that into a loan for you.

The gap is close to its long-run average of 1.89 points. Right now this layer isn't adding to or subtracting from what you'd historically expect to pay.

What this means for you

Right now your rate is tracking Treasury yields fairly closely. When you hear the 10-year moved, expect your quote to move roughly with it — this layer isn't distorting the relationship much at the moment.

The backdrop

The wider economy isn't the problem.

Put together: the market is frozen because of rates, not because the economy is breaking. That's actually the reassuring part of this forecast.

NewSupply building

More homes are being built than a year ago.

Rates and the economy explain today's prices. This explains tomorrow's inventory — what builders are breaking ground on right now, months before it ever hits a listing site.

If you're buying, this is the part of the forecast that works in your favor. Permits and starts climbing means more homes to choose from later this year and next — supply arriving on a builder's schedule, not a rate cut's.

So what should you do

Same forecast. Different move, depending who you are.

Buying

2027 is quietly the best window in years.

Flat prices and stable rates mean no rush — but the forecast also points to less competition than this year.

Selling

More buyers are coming — but only 1.0% price growth.

2027 brings liquidity, not appreciation. Price it right the first time instead of waiting on a market that isn't running away.

Own a high-rate mortgage

Refinancing is forecast to grow sharply.

Not because rates are falling — because so many people bought high in 2023–2025. Your break-even may have already arrived.

The forecast says the rate line barely moves through 2027 — so locked-in households thaw through life events, not rate rescue. See the full 13-year history of how we got here.
