Oakland County

Oakland County sits at a 3.6% cap rate on a $365,349 median purchase price, with gross rent of $1,685 per month producing a rent-to-price ratio of 0.55%, well below the 1% threshold that cash-flow buyers use as a first filter. Run a conventional underwrite at 6.85% on an 80% LTV loan and the numbers get worse: $1,915 in monthly mortgage payments, $590 in estimated operating expenses, and an estimated cash flow of negative $820 per month, yielding a cash-on-cash return of -11.71%. The appreciation score of 80 out of 100 and a 3.1% year-over-year home price gain tell you where this market's value actually sits. Oakland is squarely on the appreciation end of the spectrum, a market where you are effectively paying a premium today and betting on continued price growth to generate your return.

That profile suits exactly one type of buyer: an appreciation-oriented investor with the balance sheet to carry negative monthly cash flow and the conviction that a market anchored at $365,349 in median home price, $92,620 in median household income, and an affordability index of 71 will continue to attract and retain high-income residents. The cash-flow buyer has no business here at current prices and rates. A value-add operator might find a narrow opportunity, but the entry price leaves very little margin for error: you would need to manufacture a significant rent premium over the $1,685 median just to approach breakeven, and that assumes you can acquire below median. The stability score of 50 out of 100 adds another layer of caution for anyone relying on steady, predictable income from day one.

Oakland County's 1.27 million residents and $92,620 median household income create genuine underlying rental demand from tenants who can afford market rents and are likely to pay them. That income figure matters because it sets a ceiling on affordability risk; renters in this county have the earnings to absorb normal lease renewals without vacancy spikes driven by pricing out the renter pool. That said, income alone does not fix the negative carry problem at current prices.

Carry costs deserve serious attention in this county. At a state-average effective property tax rate of 1.54%, Oakland is in high territory, and at the given purchase price that translates to $5,626 in annual property taxes, or roughly $469 per month. Add $79 in monthly insurance and total tax-and-insurance expense runs $548 per month before you touch maintenance, management, or vacancy reserves. That $548 figure is 32.5% of gross monthly rent, which is an unusually heavy fixed-cost load and one of the primary reasons cash flow is as negative as it is. Per the note on the data, 1.54% is a state-average estimate from Tax Foundation 2024; actual Oakland County township-level millage rates may differ, and in some Michigan townships with school and special assessment levies, the effective rate runs higher. This line item deserves its own cell on your underwrite before you close.

The clearest risk here is leverage and carry duration. A market with a -11.71% cash-on-cash return at entry is only acceptable if you have a clear hold thesis, access to cheap capital, and confidence in the appreciation trajectory. If rent growth stalls or home price appreciation reverts toward zero, you are left holding an asset that costs you $820 per month with no compensating gain. Concentration risk is also worth naming: Oakland is a large, high-income suburban county adjacent to Detroit, and its performance is meaningfully tied to the broader Metro Detroit employment and migration picture. Any deterioration in that regional story would hit both rents and values here before it shows up in more diversified markets.

The neighboring county comparison sharpens the picture. Saint Clair County ($246,890 median, 0.536% rent-to-price ratio) and Lapeer County ($280,839 median, 0.508% ratio) both come in at lower price points but also produce weaker rent-to-price ratios, so they are not straightforward cash-flow upgrades. Kalamazoo County ($263,226 median, 0.592% ratio) and Berrien County ($262,819 median, 0.671% ratio) both offer meaningfully better rent-to-price ratios at lower entry prices; Berrien in particular at 0.671% is the closest of this group to viable cash-flow territory. All four neighbors carry overall scores of 62 to 64, essentially matching Oakland's 63, so you are not trading away quality for yield. The case for choosing Oakland over any of these neighbors comes down to one question: do you believe the $92,620 income base, the population scale of 1.27 million, and Oakland's long-term track record as Metro Detroit's premier suburban market justify accepting deeply negative cash flow for what is a modestly higher appreciation score? If your strategy is income now, one of the neighbors, particularly Berrien or Kalamazoo, will serve you better. If your strategy is long-term capital appreciation in a large, high-income market and you can fund the carry, Oakland earns its place in the conversation.
