Data: HUD FMR FY2024 + Zillow ZHVI April 2026 + Freddie Mac rates. Last updated June 2026.

Investment Summary

As of 2026, Groton, CT has a 3.1% cap rate, indicating limited cash flow potential at current prices of $474,374 median.

Groton is primarily an appreciation play with limited cash flow potential. At $474,374 median home price, Groton requires significant capital. A 20% down payment alone is $94,874. With 3-bedroom rents around $2,240/month, the 3.1% cap rate tells the story. Cash flow is deeply negative at -$1,360/month with standard assumptions. This market requires appreciation to justify the investment.

At 0.49% on the 1% rule, rents are low relative to purchase prices. You'd need a significant discount from asking price to make the numbers work. DSCR of 0.49 is below 1.0, meaning rental income doesn't cover the mortgage. DSCR lenders will likely decline this market at current prices.

Bottom line: Consider Groton only if you believe in long-term appreciation. The numbers don't support cash flow at today's prices and rates.
