How it compares in Port Huron

Over the last 90 days, 130 homes sold in Port Huron for a median of $180,000, about $123 per square foot, and the typical one went under contract in 8 days. This home is listed at $3,500,000, or $369 per square foot, 200% above the city median, and has been on the market 192 days. Size, condition, updates and the exact street all move the number, so treat this as context. See recent Port Huron sales or ask us for the comparable sales on this one.

Property taxes for a new owner

The current owner pays about $36,258 a year. A buyer who lives here would pay about $35,941 to $73,015 a year once the taxable value resets after the sale, at the 2025 homestead rate of 41.31 mills for Port Huron City and Port Huron schools, plus the 1% administration fee. Michigan resets a home's taxable value the year after it sells, so the seller's bill isn't a good number to budget with. See the math.
