Cass County

Cass County's numbers place it squarely in appreciation territory, with cash flow that is genuinely difficult to make work at current prices and rates. The gross rent-to-price ratio sits at 3.91%, which on a $339,508 median purchase price generates a cap rate of just 2.54% using the model's expense assumptions. At a 6.85% financing rate with 20% down, the estimated monthly mortgage is $1,780 against roughly $1,107 in median rent, producing an estimated cash flow of negative $1,060 per month and a cash-on-cash return of -16.29%. Those are not rounding errors; they are structural. The appreciation score of 83 out of 100 and 3.97% year-over-year home price growth tell you what this market rewards: equity accumulation, not monthly income.

The investor this market suits is someone buying for long-term appreciation who can carry a significant monthly shortfall, or a buyer who can substantially beat the median rent through value-add work, premium unit positioning, or multi-family density. A pure cash-flow buyer should stop here: the math does not close at current prices and a conventional 30-year mortgage. An appreciation buyer with sufficient reserves and a 5-to-10-year horizon has a case, given the 3.97% annual price growth and a population base of 186,328 that is large by North Dakota standards. A value-add operator is the most viable third path, but only if acquisition is below the $339,508 median, because there is no margin for error at full market pricing with a 2.54% cap rate.

Cass County is home to Fargo, the state's largest city and the economic center of the region. The county's affordability index of 57 and stability score of 50 reflect a market that attracts residents but has priced out straightforward rental returns. The county's size relative to North Dakota's 43-county universe matters: at a population of 186,328, this is where jobs, healthcare systems, university enrollment at North Dakota State University, and regional retail concentrate. That concentration supports rental demand from a pool of tenants who are employed and mobile within the metro, which backstops occupancy even when cash flow is negative, but it does not conjure rent levels that overcome a 3.91% gross yield at today's interest rates.

The combined monthly tax and insurance load of $376, derived from a state-average effective property tax rate of 0.98% and an insurance rate of 0.35%, is already embedded in the -$1,060 cash flow estimate. The 0.98% rate is flagged as normal, which is accurate: North Dakota sits near the national median on property taxes, so there is neither a penalty nor a tailwind here worth calling out independently. That said, the note accompanying this data is worth taking seriously: the 0.98% figure is a state-average estimate from Tax Foundation 2024 data, and your actual county or township rate may differ, so confirm the specific assessed rate for any address before finalizing your underwrite.

The primary risk in Cass County is concentration. One county, one city, and one regional economic engine mean that any meaningful slowdown in Fargo's employment base would hit both rents and appreciation simultaneously. The overall score of 53 out of 100 and a national percentile ranking of 30th out of 1,000 counties suggest the market is not broadly competitive on an investment basis despite the local appreciation story. Investors should also be attentive to North Dakota's weather-related insurance dynamics: hail, wind, and freeze exposure can push actual insurance costs above the 0.35% state-average estimate used here.

Against its neighbors, Cass County is the highest-priced market in the comparison set by a wide margin. Burleigh County, which includes Bismarck, prices at $352,675, only slightly higher, but carries a rent-to-price ratio of 4.45% versus Cass's 3.91%, with a median rent of $1,307 and an overall score of 58 versus Cass's 53. That differential matters: Burleigh's yield is meaningfully better on a like-for-like comparison, and its overall score edges Cass out. Walsh, Sargent, McHenry, and Adams counties all come in at median prices between $139,000 and $171,000, which opens up entirely different cash-flow math, though their overall scores cluster between 50 and 58 and their smaller populations mean thinner tenant pools. Choose Cass County over its neighbors when your thesis is appreciation in the largest North Dakota metro and you have the capital to carry negative cash flow. Choose Burleigh when you want a similarly sized city exposure with a better starting yield. Choose the lower-priced rural counties only if cash flow is the priority and you are comfortable with the liquidity and tenant-pool constraints that come with small-market North Dakota investing.
