Hudson County

Hudson County sits at a gross rent-to-price ratio of 5.66%, which sounds reasonable until you run the full stack. At a $636,231 purchase price with 20% down, the model spits out a 3.68% cap rate and a cash-on-cash return of negative 11.37%, driven by a monthly mortgage of $3,335 against median rent of $2,998. That is a market where the income does not cover the debt at current rates, full stop. Home price appreciation came in at 0.78% year-over-year, which is not the kind of number that rescues a negative-carry position quickly. Hudson scores 55 on cash flow and 58 on appreciation out of 100, landing in the bottom quarter nationally at the 25th percentile. This is not a market where the math works passively at today's rates and prices; it is a market where you need a thesis that goes beyond "buy, rent, collect."

The investor this market suits is not a turnkey cash-flow buyer. The numbers make that clear. A pure appreciation buyer needs conviction that 0.78% annual price growth will accelerate meaningfully, and there is no data here to suggest that is imminent. The most defensible angle is value-add: find assets trading below the $636,231 median where significant rent upside exists through renovation or repositioning, or target multi-family properties where unit-level economics differ from the single-family median. Even then, the affordability index of 27 out of 100 tells you the renter pool is under financial pressure relative to local prices, which can constrain how far rents move. A median household income of $86,854 against a median rent of nearly $3,000 means renters are already spending a substantial share of gross income on housing, limiting organic rent growth unless supply tightens sharply.

No economic anchor data was provided for Hudson County, so employer-specific demand drivers cannot be addressed here.

The tax and insurance picture is a serious underwriting problem. At a state-average effective property tax rate of 2.49%, Hudson carries an estimated annual property tax of $15,842, plus $1,336 in insurance, putting combined monthly tax and insurance at $1,432. That is not a rounding error; it is the single largest line item after the mortgage itself, and it is the primary reason estimated monthly expenses hit $1,049 on top of that $3,335 mortgage. New Jersey's rate is very high by any national standard, and at 2.49% it deserves its own underwriting scenario. The honest caveat is that this is a state-average estimate from Tax Foundation 2024 data, and actual county or township rates in Hudson can differ, sometimes materially. Before you sign a contract, pull the specific tax bill for the subject property. A meaningful spread from the state average in either direction will change your cap rate calculation significantly.

The concentration risk here is density and price. Hudson County's 712,029 residents compressed into a small geographic footprint means you are underwriting a market where supply constraints are structural and land is scarce, which supports long-term values but also means acquisition costs stay elevated. Affordability at 27 puts downward pressure on the buyer pool that would eventually take your asset off your hands, which extends your hold horizon whether you plan for it or not. No vacancy or regulatory data was provided, so those risks cannot be quantified, but investors should independently verify local rent control ordinances, which are common in Hudson County municipalities including Jersey City.

Against its neighbors, Hudson's 5.66% rent-to-price ratio is the best of the group. Monmouth is at 4.64%, Bergen at 4.53%, Essex at 4.35%, Passaic at 4.76%, and Union at 5.06%. Hudson wins on that metric by a clear margin, which is the affirmative case for choosing it over any neighbor. Passaic and Union come in cheaper on entry, at $574,942 and $614,241 respectively, and their rent-to-price ratios, while lower than Hudson's, may produce better cash-on-cash outcomes depending on local tax rates. Bergen and Monmouth are more expensive with worse rent ratios, which makes the value proposition even thinner. If your goal is the best rent coverage relative to purchase price among northern New Jersey counties, Hudson is the answer. If your goal is the clearest path to positive cash flow, none of these five counties solve the problem at current rates, and Passaic or Union may simply limit the bleeding more than Hudson does.
