Fed Hikes Rates: Mortgages Follow

Mike walks through what the Fed’s hike means for buyers and sellers in Belmont and Watertown.

What actually changed?

On September 16 the Fed voted 12 to 0 to raise its benchmark rate by a quarter point, to a range of 3.75% to 4.00%. The reason it gave was inflation that has not come down the way it wanted, with energy prices doing a lot of the pushing. The next meeting is October 28.

It is worth being clear about one thing, because we get asked about it constantly. The Fed does not set mortgage rates. It sets the rate banks charge each other overnight. Mortgage rates are priced off the bond market, and they had already been rising for weeks before the vote. The Mortgage Bankers Association now shows six weekly increases in a row. What the hike did was tell investors the Fed is worried about inflation sticking around, and rates kept moving up on that message.

What does 7.58% cost in Watertown and Belmont?

A year ago, Freddie Mac had the 30-year fixed at 6.30%. Here is the same median Watertown home, about $884,000, with 20% down at both rates.

Another way to see it: the monthly payment that bought an $884,000 home a year ago now supports a purchase of about $776,000. The house did not get cheaper. The budget got smaller.

Belmont works a little differently. The median single-family sale there was $1.55 million over the last 90 days, so most purchases need a jumbo loan, and jumbo rates do not move in lockstep with the averages above. The Mortgage Research Center had the 30-year jumbo at 7.60% this week. On that median with 20% down, that comes to roughly $8,750 a month in principal and interest. Jumbo pricing can vary quite a bit from one lender to the next, so it pays to compare.

What else is happening in the local market?

Rates are only half the story this fall. Supply is up, and homes are taking a little longer to sell.

This is not a buyer’s market. Well priced homes in both towns still draw real interest. But buyers have more choice and a bit more time than they did in the spring, and that changes how negotiations go.

What we are telling buyers

1. Do not build your plan around rates falling. They might, and if they drop meaningfully over the next year, waiting will have been the right call. But the Fed just leaned the other way, and waiting has a cost if rates do not cooperate.
2. Sort out your rate lock before you write an offer. Rates are moving day to day right now. Ask your lender about lock periods and float-down options early.
3. Ask about a buydown. Paying points lowers your rate for the life of the loan, and a seller can pay for those points as a concession. On some deals that helps your monthly payment more than a price reduction of the same amount.
4. Use the extra time. Longer market times mean more room to negotiate on price, inspections and terms than buyers had a few months ago.

What we are telling sellers

1. Price it right from the first day. Every buyer who walks through your home has already done the payment math above. Homes that come on high tend to sit, and they usually end up selling for less than they would have at the right price.
2. Think about a credit instead of a price cut. If a buyer’s monthly payment is the sticking point, a seller-paid rate buydown can solve more of the problem than a small reduction in price.
3. Expect careful buyers. Plan for thorough inspections and more back and forth than you may have seen in the spring.

None of this means the fall market is a bad time to make a move. It means the numbers matter more than they did a year ago, and the people who plan around them are the ones who come out ahead.
