Rental Property in Connecticut: What the Numbers Actually Look Like

  • Connecticut's 1.81% effective property tax rate is the second-highest in this seven-state set, and Hartford County's 2.40% is higher than New Jersey's statewide rate. On Hartford's own $418,818 median that is $10,051.63 a year.
  • The Hartford County example needs $4,235.95 a month of rent to break even — 1.01% of purchase price. It is the only property in this series that genuinely requires the full 1% rule, and its cap rate is 2.37%.
  • Statewide worked example at 25% down on the $485,000 median: a 2.99% cap rate, a DSCR of 0.50, cash flow of -$1,211.21 a month, and a -10.70% cash-on-cash return on $135,800 of cash in.

Connecticut asks you to pay three times.

You pay a high entry price — a $485,000 statewide median, and $708,500 in Fairfield County. You pay a high effective property tax rate — 1.81% statewide, and 2.40% in Hartford County, which is higher than New Jersey's statewide rate and the highest county figure anywhere in this seven-state series. And if the property is anywhere near Long Island Sound, you pay a third time in the form of a percentage hurricane deductible that can run to 5% of the dwelling limit within 2,600 feet of the water.

Insurance itself, at $2,050 a year at $300,000 of dwelling coverage, is the least of your problems here. Property tax is 4.28 times the insurance bill.

The clearest single number in this article is the Hartford County example in Section 5. It needs $4,235.95 a month of rent to break even on cash flow, against a $418,818 purchase price. That is 1.01% of price per month — the only property anywhere in this series that genuinely requires the full "1% rule," and it requires it because of the tax rate.

If you take one thing from this article: in Connecticut, get the town's mill rate before you get excited about the price. Connecticut levies at the municipal level, the spread between towns is enormous, and the county figures below are averages over towns that differ wildly.

A note before you start: this is general educational information about how rental property arithmetic works in Connecticut. It is not investment, tax, insurance, or legal advice, and it is not a recommendation about any property. Connecticut has no county governments in the ordinary sense — property tax is assessed and levied town by town, and the county effective rates used here are averages, not bills. Talk to a Connecticut CPA about tax treatment, a licensed Connecticut insurance agent about a real quote, and a Connecticut real estate attorney about anything contractual. Connecticut is an attorney-closing state, so you will have one.
