This week's lean

The market held its breath this week.

Neither side gave much ground. Prices and pace stayed close to where they were last week.

Prices eased again this week, and the bigger story is where they eased the most. New construction pending prices took the sharpest drop. If you are shopping for a brand new home, that shift is worth understanding.

Let me break it down.

Existing homes

Resale homes for sale carry a typical asking price of $627,249, down $3,591 from last week. There are 900 of them on the market, just two more than last week, so your choices held steady. These homes have been sitting for a median of 32 days, unchanged from last week.

Now the homes that actually went under contract. Their median price is $565,340, up $1,740 from last week, with 541 homes pending, 16 fewer than last week. Those homes took a median of 14 days to go under contract, two days faster than last week. So asking prices eased while the homes buyers committed to went for a touch more, and they went quickly. If you are selling, that is your reminder: price it right and buyers move fast.

New construction

Brand new homes still list higher than resale on average. The median asking price for a new build is $613,045, down $9,359 this week. There are 450 new homes for sale, 20 more than last week, so builders kept adding options. Those homes have been sitting for a median of 66 days, one day faster than last week. That is roughly twice as long as resale homes sit, so if a new build is your goal, there is plenty to compare and no reason to rush.

On the pending side, the story is different. New homes going under contract carry a median price of $590,546, down $33,414 from last week. That is the biggest one-week price move anywhere in the county this week. There are 125 under contract, two more than last week, and those took a median of 55 days to go under contract, three days slower than last week. If I had to guess, builder incentives and rate buydowns are showing up in those agreed prices. For a buyer, that can mean real room to negotiate on a brand new home right now.

The bigger picture

The 30-year fixed mortgage averaged 6.95% as of September 17, per Freddie Mac. That is the single biggest force on buyer budgets, and it is why prices keep moving in small steps rather than big jumps. Higher rates trim what a monthly payment can buy, which pushes sellers and builders toward flexibility on price.

Here is my take. Builders have inventory to move and tools to help buyers afford it, which is part of why new construction pending prices came down so much this week. Resale sellers, on the other hand, are still getting solid agreed prices when they price to the market, and buyers there are acting fast. Two different markets, two different playbooks.

None of this calls for panic in either direction. If you are buying, get clear on your must-haves and line up a lender who can move quickly, and ask about builder incentives if a new home appeals to you. If you are selling, price to the market and prepare your home well. And if you just want to know how these numbers fit your own plans, that is exactly the conversation I am here for.
