Box Elder County

Box Elder County sits at a 2.38% cap rate with a gross rent-to-price ratio of 0.0366%, putting it squarely in appreciation territory rather than cash-flow territory. The numbers are blunt: at a $445,062 purchase price, a 20% down payment, and a 6.85% rate, the modeled mortgage runs $2,333 per month against median rent of $1,359. Add $476 in estimated expenses and $304 in monthly tax and insurance, and you're looking at negative $1,450 in monthly cash flow and a cash-on-cash return of negative 17%. The price-to-rent ratio implies the market is pricing in future appreciation, not current income. Year-over-year home price growth of 1.17% is positive but modest, suggesting the appreciation thesis is a longer-duration bet rather than a near-term catalyst.

This market is not for the cash-flow buyer. A cash-on-cash return of negative 17% means you're writing a check every month, and the cap rate of 2.38% would not pencil even for an all-cash buyer seeking income. The appreciation score of 62 out of 100 is the one number that gives an investor a reason to look twice, but it needs to be weighed against an affordability index of 36 and a national percentile ranking of 8 out of 1,000 counties. That ranking reflects how poorly Box Elder competes on investment fundamentals relative to the broader universe. The buyer who belongs here is either building a long-term hold with an expectation of regional population growth pushing both prices and rents higher, or a value-add operator who can force appreciation and lift rents materially above the $1,359 median. Even then, the entry math requires conviction that rents can move significantly, because the spread between mortgage carry and gross rent is over $970 per month before any expenses.

The tax and insurance picture offers one genuine tailwind. Utah's state-average effective property tax rate is 0.63%, which the Tax Foundation classifies as low, and that estimate is already baked into the $304 monthly tax-and-insurance figure (with the honest caveat that actual county and township rates in Box Elder may differ). On a $445,000 asset, $2,804 in annual property taxes is materially lower than what an investor would face in Illinois, New Jersey, or Texas at comparable price points. The $846 annual insurance cost is also modest. Combined, that $304 monthly figure is a real underwriting tailwind and partially offsets what would otherwise be an even more negative cash-flow position. Investors running comps against higher-tax states should weight this accordingly.

The principal risk here is concentration and scale. Box Elder County has a population of 58,291. A small population base means the rental demand pool is narrow, tenant turnover is more disruptive, and any employer contraction hits occupancy harder than it would in a metro with diversified demand. The stability score of 50 is middling, not a signal of resilience. No economic anchor data was provided for this county, so no employer-level demand analysis can be offered. Any investor underwriting here should do independent diligence on the local employer base and commute patterns relative to the Wasatch Front before committing capital.

On a relative basis, Box Elder compares unfavorably to most of its Utah neighbors on income generation. Cache County, the nearest comp by price ($454,811 median), produces a rent-to-price ratio of 0.0395 versus Box Elder's 0.0366 and carries an overall score of 48 versus Box Elder's 43. That 290 basis point spread in rent-to-price ratio, at these price levels, translates to a meaningful difference in gross income per dollar deployed. Washington County runs a rent-to-price ratio of 0.0434, the highest in the comparison set, and while its median home price of $522,143 is higher, the gross income yield is substantially better. Salt Lake County is priced at $558,754 with a rent-to-price ratio of 0.0345, slightly worse than Box Elder on yield but with a larger and more diversified tenant base. Summit County at $1.28 million median and a ratio of 0.0333 is in a different asset class entirely. The investor who should choose Box Elder over Cache County is one who expects Box Elder's relative affordability to attract spillover demand from the Wasatch Front and believes that demand will compress the rent-to-price gap over time. Without that specific thesis, Cache County's current numbers are more favorable on almost every metric that matters for a buy-and-hold rental.
