People move between our communities constantly, and the comparison almost always starts in the wrong place: what does a house cost in Lakewood versus what does it cost in Boro Park. That question has an answer, and the answer is close to useless on its own, because the purchase price is the one cost you pay once.
What determines whether you can actually live in a house is the carrying cost — everything you pay every month for as long as you own it. Across our markets, the carrying cost on identical purchase prices can differ enough to change which house you can afford.
Property tax is the big one, and it moves the most
New York City and the New Jersey suburbs tax property on fundamentally different systems, and the practical result is that effective property tax rates in the New Jersey towns run substantially higher than in Brooklyn. New York City taxes a Class 1 home on a fraction of its market value and caps how fast the assessment can rise, which over time pushes the effective rate on a long-held house well below the headline number. New Jersey towns assess closer to true value and levy a rate that funds schools and municipal services directly.
Do not take a rate from an article, including this one. Every one of these municipalities publishes the current numbers, and they change annually. Pull the actual tax bill for the actual address — in New York City through the Department of Finance property records, in New Jersey through the county or township assessor. On a listing you are seriously considering, the tax figure belongs in your monthly math before anything else, because in the New Jersey markets it is frequently the second-largest line after the mortgage itself, and occasionally the largest.
Two more things people miss. First, a New Jersey tax bill can be reassessed after a sale, so what the current owner pays is not necessarily what you will pay. Second, in New York City a long-held house may carry an assessment far below market — a benefit that partly resets in a way that catches new owners off guard.
The rental unit changes the whole comparison
The Brooklyn housing stock is full of two- and three-family houses where a legal rental unit carries a meaningful share of the payment. Much of the suburban stock is single-family by design and by zoning. Comparing a Brooklyn two-family against a Lakewood single-family on price alone compares an asset that produces income against one that does not.
Do the comparison on net monthly cost: payment plus taxes plus insurance plus utilities you cover, minus rent you actually collect. And use a rent you can prove from a lease, with a vacancy allowance — not the number in the listing. Whether that unit is legal is the whole ballgame; see what your certificate of occupancy allows before you count a dollar of it.
The costs that only show up after you move
- Heating and cooling. A detached suburban house with more exterior wall and more square footage costs more to heat than an attached Brooklyn rowhouse with neighbors on both sides. This is a real four-figure annual difference in some comparisons.
- Cars. A community where you drive to everything means a second car, more insurance, and more fuel. A community where you walk to everything may mean none of that. This routinely swamps the tax difference and is almost never in anybody's spreadsheet.
- Water and sewer. Municipal billing varies; some suburban towns bill separately for both, and a house with a lawn uses considerably more.
- Insurance. Detached suburban houses, flood zones and older Brooklyn buildings each price differently. Get a real quote on the actual address rather than assuming.
- Maintenance. A house with its own roof, own boiler, own driveway and own trees has more of everything that eventually breaks than an attached house sharing walls.
How to run the comparison properly
Build one monthly number for each house you are comparing, using the same categories for both. Mortgage payment, real property tax from the real bill, insurance from a real quote, utilities from the seller's actual bills — ask for them, sellers usually have them — transportation, and a maintenance reserve. Then subtract verified rental income.
The mortgage calculator handles the payment, taxes and insurance portion. Do the arithmetic on both houses on the same day, with the same assumptions, and keep the sheet — it is the only way to see that the cheaper house is sometimes the more expensive one.
And once you have the monthly numbers, look at what each community actually gives you for the difference. Walking distance to a shul and a school is not a soft factor — it is the thing that decides whether you need the second car, and it is why we put real walking times on our listings instead of a straight line on a map.
