Last Week of September 2026 Market Update: Mortgage Rates Reach 6.95% for Grand Blanc, Fenton & Linden

It is the final week of September 2026, and the local housing market has hit a real inflection point. The national 30-year fixed mortgage rate climbed to 6.95 percent for the week ending September 17, its fourth consecutive weekly increase per Freddie Mac, while fall inventory across Grand Blanc, Fenton, Linden, Columbiaville and Tyrone Township keeps giving buyers more to choose from. This update covers the fresh rate numbers, what the move means for monthly payments, the local projects and events shaping the next ten days, and what buyers and sellers should do before October.

Rates March Higher: 30-Year Fixed at 6.95%

The national average 30-year fixed rate was 6.95 percent for the week ending September 17, 2026, according to Freddie Mac's Primary Mortgage Market Survey. That is up from 6.76 percent the prior week and marks the fourth straight weekly increase, a run that started in the high 6.6s in late August. The 15-year fixed rate averaged 6.26 percent the same week. Rates have now moved about a quarter of a point since late summer, which is meaningful on a monthly payment but not enough to break the local market, where motivated buyers and sellers on both sides are still finding common ground.

Michigan lenders continue to quote 30-year fixed rates from the mid-6s into the low 7s depending on program, points and lock date, so the national headline is a guide, not your personal quote. The structure of your loan matters more than the headline rate: a rate lock pins down today's number while you shop, a seller credit can offset closing costs, and a temporary buydown can soften the first couple of years of payments. Ask for two or three written quotes before you choose a lender.

What a Quarter-Point Move Means for Your Payment

On a $400,000 loan, the difference between 6.76 and 6.95 percent works out to roughly $51 a month, about $610 a year, before taxes and insurance. Here is what principal and interest look like at the current rate for common loan sizes in the region:

Two strategies soften the move. First, ask the seller for a credit toward closing costs, which reduces the cash you bring and can be used to buy down the rate. Second, lock your rate as soon as you are pre-approved; a 30, 45 or 60-day lock protects you while you tour. With inventory up and sellers who want to close before the holidays, that kind of help is increasingly on the table as the season wears on.

Grand Blanc: More Choices at a Higher Median

Grand Blanc's market has grown noticeably since spring. Movoto's September snapshot puts the median listing price near $324,900 with roughly 331 active listings, up from earlier in the month as fall sellers list, and snapshots at this scale change daily as homes come and go. The practical read: buyers touring Grand Blanc this week have genuine selection, and the strongest, best-priced homes in the top school neighborhoods still go pending quickly.

One thing to know before you hit the road: Genesee County Road Commission crews have improvement projects running through the fall in the Orchard Haven and Wishing Well subdivisions on the Grand Blanc Township side, including repaving work, so a couple of tour routes may include detours and construction traffic. Ask your agent to route around them, and give yourself extra drive time when stringing together showings.

Fenton: Premium Values, a Busy Fall Calendar

Fenton remains the region's premium resale market. Movoto lists a median listing price near $397,000 with roughly 250 active homes, and Zillow's average home value holds near $366,500. The competitive 48430 ZIP keeps move-in-ready homes turning over fast, and the mix of lake access, downtown dining and the new retail corridor keeps demand steady through the season.

Also on the calendar: the City of Fenton's 2026-2027 local roads project is reconstructing Elm Street, Long Street, Hillview Terrace and Drive, Orchardview Drive, Valley Drive and Valleyview Drive, with watermain work continuing through the fall, so residents and buyers alike are navigating lane shifts on those corridors. Downtown, the fun returns with Witches Night Out in historic downtown Fenton on Friday, October 9 beginning at 4 p.m., and the Fenton Bluegrass Festival follows on Saturday, October 10 per the city calendar. Both are free, family-friendly ways to see the town at its busiest before you write an offer.

Linden: Thin Inventory and a Trail Opening This Tuesday

Linden's supply stays thin, with about 73 active listings per Movoto, Zillow's average home value near $344,000 and Redfin's three-month median sale around $320,000. The handful of new listings each week draw visits quickly, so if Linden's school district and small-town feel are priorities, your agent should watch every new listing closely and be ready to tour the day it goes live.

The big news this week is the ChoiceOne Bank Trail: the roughly 2.2-mile paved shared-use path connecting Linden and Fenton officially opens with a ribbon cutting at 10 a.m. Tuesday, September 29 near the corner of Silver Lake Road and Jennings Road in Fenton. For buyers, the trail is more than scenery. It links the two town centers along the north shore of Silver Lake and adds a daily amenity within walking distance of nearby homes, which supports values over time. Our full guide to what the opening means for the corridor covers the details: The ChoiceOne Bank Trail Opens September 29.

Columbiaville & Tyrone Township: The Quiet Fall Market

Columbiaville continues to offer some of the largest yards per dollar in the region, with thin supply that swings headline stats with each closing. Its average home value sits near $265,000 for the city and roughly $263,000 for the 48421 ZIP, up about 6.6 percent year over year per Zillow. When a well-priced home appears along the Southern Links Trailway or the Holloway Reservoir corridors, it still goes quickly, so prepared buyers with pre-approval in hand have the edge.

Tyrone Township lives on custom acreage homes with Hartland Consolidated Schools as the quiet top draw, and inventory runs newer than average. Oaks of Tyrone by Big Sky Development continues with new custom packages starting around $629,900 on roughly one-acre homesites, minutes from Fenton, Linden and the US-23 commute corridor. In both communities the fall play is the same: get fully pre-approved, watch closely and move fast on the right match.

A Fall Community Calendar to Plan Around

The next ten days double as a neighborhood check. Tuesday morning, September 29 is the ChoiceOne Bank Trail ribbon cutting in Fenton. Friday, October 9 brings Witches Night Out to downtown Fenton, and Saturday, October 10 is the Fenton Bluegrass Festival, both per the city calendar. The Grand Blanc City Farmers Market keeps its late-season Thursday evenings running through mid-October, and fall color typically starts arriving across the Southern Lakes in the first week of October, per the Old Farmer's Almanac 2026 forecast covered in our fall colors guide.

These events show a town at its busiest, which is exactly how you want to evaluate a community before you buy. Walk the festival, ride the new trail, meet neighbors, and you will learn more than any listing sheet will tell you.

The Bottom Line for the Final Week of September

Rates are higher than they were a month ago, but the market is far from frozen. Grand Blanc keeps adding listings, Fenton holds its premium, Linden turns thin supply over fast, and the country communities reward prepared buyers. Our earlier late-September snapshot laid out the same open window, and this week's numbers sharpen it: a quarter point in rates is a real cost, and locking in while inventory is up is the strongest combination a buyer can have this fall.

For sellers, the crisp light and evening showings make this the best photography and marketing month of the year, and pricing for the fall buyer still commands attention. For buyers, the math favors acting before the October holiday season distracts the market, and an offer written in the next ten days can still close comfortably before Thanksgiving.
