New London County

New London County sits at a gross rent-to-price ratio of 5.85%, which places it squarely in appreciation territory rather than cash-flow territory. The 3.8% cap rate confirms it: at a $430,928 purchase price and $2,099 median monthly rent, the income simply does not cover the cost of debt at current rates. Running the standard 20% down scenario at 6.85% produces a monthly mortgage of $2,259, and when you layer in estimated expenses of $735, the modeled cash-on-cash return lands at negative 10.84%, with a monthly cash-flow deficit of roughly $895. The appreciation score of 92 out of 100, paired with 6.98% year-over-year home price growth, tells you what this market is actually selling: equity accumulation, not current income. An affordability index of 38 signals that a meaningful portion of the local population is priced out of ownership, which typically supports rental demand structurally, but the math at today's financing costs does not make that demand profitable at acquisition.

This market suits an appreciation-oriented buyer with a long hold horizon and the balance sheet to absorb negative carry, or a cash buyer who can sidestep the debt service problem entirely. At zero leverage, a 3.8% cap rate is at least a positive return, and in a market printing nearly 7% annual price growth, the total return case has some logic to it. The cash-flow buyer has no business here at these numbers unless they are buying substantially below median, doing value-add work to push rents, or both. A value-add operator hunting distressed assets that can be repositioned to rents materially above the $2,099 median has the most plausible path to a workable return, but the underlying cost basis is still working against them at a $430,927 median price. The stability score of 50 out of 100 is a caution flag, suggesting this market carries more volatility risk than a pure appreciation thesis can comfortably absorb.

The county's economic base includes Naval Submarine Base New London in Groton, which is one of the largest naval installations on the East Coast, as well as Electric Boat, a General Dynamics division that is a primary submarine builder and among the largest private employers in the state. These anchors generate a military and defense-contractor workforce with relatively stable income and persistent rental demand, particularly for properties within reasonable commuting distance of the Groton-New London corridor. Federal defense employment and long-term government contracts tend to insulate the local labor market from cyclical downturns more than a typical market, which partially explains the appreciation score and gives some credibility to the rental demand side of the thesis even when current cash flow is negative.

The tax and insurance picture deserves serious attention on your underwrite. Connecticut's state-average effective property tax rate of 1.98%, flagged as high, translates to $8,532 annually on a $430,927 purchase, and when combined with $1,164 in annual insurance, total monthly tax and insurance comes to $808. That is a hard cost that consumes nearly 39% of the $2,099 gross rent before you touch mortgage principal or interest, maintenance, vacancy, or management. Connecticut is consistently near the top of national property tax rankings, and at 1.98%, this rate demands its own line on your underwrite. The note from Tax Foundation 2024 data is worth taking seriously: state-average estimates can mask significant variation at the county and township level, so pulling the actual mill rate for your specific target municipality is not optional here before you commit.

Compared to neighboring counties, New London carries the highest median home price among those evaluated, at $430,927, while its rent-to-price ratio of 5.85% is middle-of-the-pack. Tolland County offers the most attractive rent-to-price ratio in the group at 6.48% on a $385,938 median price, meaning more rent per dollar deployed and a meaningfully lower cost basis. Hartford County and New Haven County both sit near 6.0% rent-to-price at prices $65,000 to $45,000 below New London's median, making either a more defensible cash-flow entry point. Windham County is the cheapest at $357,199 but generates only 5.70% in rent-to-price and carries an overall score of 61. New London's edge is its appreciation score of 92, the highest in the data set, driven by the defense-sector economic anchors that no neighboring county can match. An investor should choose New London over its neighbors only when the thesis is explicitly long-term equity growth, when the economic stability of the Groton defense corridor is a deliberate priority, or when a specific asset is priced and structured in a way that the other counties cannot offer. For anyone underwriting to monthly cash flow in year one, one of the three neighbors with a 6.0%-plus rent-to-price ratio is a more rational starting point.
