Washtenaw County

Washtenaw County sits at a 3.93% cap rate and a gross rent-to-price ratio of 0.060, which places it squarely in appreciation-leaning territory rather than cash-flow country. At a $413,406 median purchase price and $2,082 median monthly rent, the math is direct: at 6.85% financing with 20% down, the model produces a monthly mortgage of $2,167 against estimated expenses of $729, yielding a projected cash flow of negative $814 per month and a cash-on-cash return of -10.27%. That is not a rounding error, it is the structural reality of this market at current rates. The appreciation score of 73 and a year-over-year price gain of 2.27% tell you what this market is actually selling: long-term asset growth anchored by an institutional demand base, not monthly income.

The investor this market suits is not a cash-flow buyer running a spreadsheet at current leverage. Negative $814 monthly is a loss that needs to be funded from other income or offset by a significantly larger down payment. What Washtenaw rewards is the appreciation buyer or the high-equity operator who can absorb below-market cash yields in exchange for durable price support. The affordability index of 56 and median household income of $84,245 suggest a tenant base with real purchasing power, which limits rent concessions during vacancies but does not fix the entry-price problem. A value-add operator with enough capital to buy distressed inventory below the $413K median and force rents above $2,082 could improve the picture, but even then the 3.93% cap rate ceiling is a meaningful constraint on exit pricing.

Ann Arbor, the county seat, is home to the University of Michigan, one of the largest research universities in the country by enrollment and research expenditure. That single anchor drives an outsized share of rental demand: graduate students, faculty, medical staff at Michigan Medicine, and affiliated research and technology employers create a tenant pool that is relatively stable across economic cycles. The university's health system and research enterprise also function as counter-cyclical employers. This is the core reason the stability score of 50, which is modest at face value, does not tell the whole story. Tenant demand in Ann Arbor is institutionally backstopped in a way that pure market-rate metros are not, which matters for underwriting vacancy assumptions even if the data provided doesn't give a vacancy rate directly.

Carry costs deserve serious attention here. At a Michigan state-average effective property tax rate of 1.54%, with the caveat that county and township rates may differ from that estimate, annual property taxes on a $413,406 purchase run approximately $6,366. Add $1,075 in estimated annual insurance and the combined monthly tax-and-insurance burden is $620. That $620 represents roughly 30% of the $2,082 median rent before you pay a dollar of principal, interest, or maintenance. The 1.54% rate is flagged as high, and it deserves its own line on your underwrite because it is the single biggest swing variable after the mortgage payment. Investors underwriting Washtenaw at a blended national average tax rate will be materially off.

The most concrete risk in this market is concentration. A county whose rental demand is substantially driven by a single university is exposed to any long-term enrollment contraction, remote-learning structural shifts, or state funding changes that affect the institution's footprint. Population is 370,231, which provides some diversification beyond pure student demand, but Ann Arbor's rental premium is real and its durability is partially tied to that one anchor. Regulatory risk is worth noting at a general level given that many university towns have moved toward tenant-protective ordinances in recent years, though no specific local ordinance data is provided here.

Against the neighbors in the provided data, Washtenaw's rent-to-price ratio of 0.060 sits above Allegan (0.050) and Ottawa (0.054), and below Van Buren (0.076) and Isabella (0.069). Van Buren at a $256,887 median price and 0.076 ratio is the clearest cash-flow alternative in the comparison set. Isabella at $214,416 and 0.069 offers even lower entry but a much thinner economic base. An investor whose primary objective is monthly income should look seriously at Van Buren or Isabella before Washtenaw. Choose Washtenaw when the investment thesis is capital preservation in a supply-constrained, institutionally anchored market, when you have the equity position to tolerate a thin or negative monthly yield, or when you are specifically targeting the Ann Arbor student and medical housing segment where premium rents and low vacancy are achievable on the right product type. If you need the asset to cash-flow at standard leverage from day one, this county's numbers do not support that outcome at current prices.
