Oakland County's 1.36% average effective rate sounds moderate — but Milford Township runs 28–30 mills while Auburn Hills runs 38–42 mills. Here's how to read the actual numbers for Kensington Ridge, Heritage in the Hills, Villa Montclair, and Reserves of Auburn Hills.
Oakland County contains some of SE Michigan's most desirable suburbs — and some of its widest property tax variation. Commerce Township runs approximately 24.6 mills for homestead properties. Oak Park reaches nearly 59 mills. Most 55+ communities in Oakland County sit in the 28–42 mill range, with significant differences driven by which school district they fall within and whether they're in a city (like Auburn Hills) or a township (like Milford).
The practical impact: a $600,000 home in Milford Township (Kensington Ridge) generates roughly $8,400–$9,000 in annual taxes after the Principal Residence Exemption. The same-priced home in Auburn Hills (Villa Montclair, Reserves of Auburn Hills) generates approximately $11,400–$12,600. That's a $250–$300/month difference from address alone — not from home size, amenities, or HOA differences.
| Location | Est. Homestead Rate | Annual Tax ($600K home) | Notes |
|---|---|---|---|
| Milford Township (Kensington Ridge) | ~28–30 mills | ~$8,400–$9,000 | Lower municipal rate for Oakland County |
| Auburn Hills (Heritage in Hills, Villa Montclair, Reserves) | ~38–42 mills | ~$11,400–$12,600 | City millage + Avondale Schools = higher total |
| Farmington Hills | ~36–40 mills | ~$10,800–$12,000 | Reference suburb comparison |
| Troy | ~35–39 mills | ~$10,500–$11,700 | Reference suburb comparison |
| Rochester Hills | ~34–37 mills | ~$10,200–$11,100 | Reference suburb comparison |
The millage gap between Auburn Hills (~40 mills) and Milford Township (~29 mills) on a $600,000 home produces an annual property tax difference of approximately $3,300. Over 10 years, that's $33,000+ in additional property taxes — before any future millage increases. This is the most important comparison to make before choosing between Kensington Ridge (Milford) and Villa Montclair or Heritage in the Hills (Auburn Hills).
By Michigan law, a property's SEV must equal 50% of its market value as determined by the assessor. SEV is the number that determines your taxable value when a property transfers. When you buy a home, your taxable value resets to the SEV in the following year's assessment.
Your actual tax base. For existing homeowners, TV is capped by Proposal A at 5% or CPI per year — often well below SEV. For new owners, TV resets to SEV at first assessment after purchase. This uncapping is the most common tax surprise in Michigan real estate.
Exempts your primary home from up to 18 mills of school operating taxes. Worth 25–35% of your total bill in most Oakland County jurisdictions. File Form 2368 with the local assessor within 90 days of closing — it is not automatic and missing the window costs you for the full tax year.
A Michigan income tax credit (Schedule CR) available to homeowners and renters with household income under $60,000. Based on the relationship between property taxes and income. Even if you don't owe Michigan income tax, you may claim this as a refund through Form MI-1040CR. Relevant for lower-income seniors in Heritage in the Hills.
Heritage in the Hills was built in 2001. Many original owners have held their homes for 20+ years with Proposal A capping their taxable value growth. A Heritage home purchased in 2004 for $210,000 may have a current taxable value of $135,000–$150,000 even if it's listing today at $280,000.
Buyers at Kensington Ridge, Villa Montclair, or Reserves of Auburn Hills avoid the uncapping issue because they're buying new — the taxable value starts at SEV from your purchase price with no history of suppressed values. Your first tax bill accurately reflects what you bought. The downside is that you don't benefit from any prior-owner cap savings either, and your taxable value will grow from a higher starting base each year.
