New London County

New London County sits at a 3.54% cap rate with a gross rent-to-price ratio of 5.45%, and the investment model runs to negative $951 per month in cash flow at a 20% down payment and 6.85% financing. Cash-on-cash comes in at -11.96%. Those numbers place this market firmly on the appreciation end of the spectrum, not the cash-flow end. The one thing working in the bull case is price growth: homes appreciated 5.83% year-over-year, and the appreciation score of 88 out of 100 reflects that momentum. An overall score of 58 and a national percentile of 49 tell you this is a middle-of-the-road market overall, ranked 5th out of 8 Connecticut counties in this dataset.

The math here selects for a specific buyer profile. A cash-flow investor running standard leverage should stop reading now, because $951 negative per month is not a rounding error, it is a structural problem at current rates and prices. The appreciation buyer, however, has a real case: 5.83% annual price growth on a $415,000 asset is roughly $24,000 in equity per year, and if that rate sustains, it more than offsets the monthly carry deficit for someone who can fund the gap. A value-add operator hunting for forced equity has a narrower path here than in lower-priced markets, given the $415,000 median, but the affordability index of 41 signals that the renter pool is constrained, which limits how aggressively you can push rents post-renovation. This is primarily a hold-for-appreciation play with a patience requirement, not an income vehicle at today's entry prices.

The carry cost picture deserves serious attention before you build a pro forma. The combined monthly tax and insurance burden runs $778, using a state-average effective property tax rate of 1.98% (Tax Foundation 2024 estimate; actual county and township rates in New London County may differ, and Connecticut's mill rate system produces meaningful variation at the municipal level). At 1.98%, the rate is high enough to deserve its own line on every underwrite, not a blended "expenses" bucket. On a $415,000 purchase, annual property tax alone runs approximately $8,217, and annual insurance adds another $1,120. That $778 monthly combined figure is already embedded in the $659 estimated expenses and the negative cash-flow outcome above, but investors used to lower-tax states should register how much of their gross rent, $1,883, is consumed before the mortgage is touched.

The neighbor comparison sharpens the decision. Hartford County offers a 6.01% rent-to-price ratio at a $365,622 median, an overall score of 62, and meaningfully lower entry cost. New Haven County matches Hartford's 6.02% rent-to-price ratio at $386,137 and also scores 60 overall. Both of those markets have better rent-to-price ratios and lower prices than New London, which makes them easier to underwrite toward break-even. Windham County is the cheapest in the group at $357,199 median and carries a 5.70% ratio with a 61 overall score. Litchfield and Middlesex are near-peers to New London in price but score lower overall. If generating current income or getting closer to cash-flow neutral is the goal, Hartford, New Haven, or Windham are the more logical Connecticut plays. New London's 88 appreciation score is the differentiated argument for choosing it instead, and that argument holds primarily for buyers who are explicitly pursuing long-term price appreciation, can absorb the monthly deficit, and have a specific thesis for why New London's growth rate continues to outpace these neighbors.

The main risks the data surfaces are affordability compression and stability. An affordability index of 41 means the buyer and renter pool is already stretched, which caps organic rent growth and creates longer re-leasing timelines when units turn. A stability score of 50 is mediocre, suggesting the market does not offer the consistent, low-variance performance that conservative buy-and-hold operators typically require. Connecticut property taxes are a known structural headwind, and the 1.98% state-average rate reinforces that this state extracts a significant annual cost that peers in lower-tax states simply don't face. Neither vacancy rates nor regulatory data are provided here, so no further claims on those dimensions are warranted.
