The Big Items
Housing: The Equity Trap vs. The Rent Squeeze
The rental market is the primary engine of wealth extraction in Cambridge. A one-bedroom unit commands $2,377 and a two-bedroom sits at $2,827. Buying is not the escape hatch it appears to be; it is simply a different form of illiquidity. While specific median home data is opaque due to low inventory, the rule of thumb is that a mortgage on a starter condo here will easily eclipse $4,000 per month with taxes and HOA fees, assuming you can even win a bid over all-cash corporate buyers. The market heat comes from a permanent influx of university staff and biotech talent who treat real estate as a scarce commodity, not a shelter. You are not just paying for square footage; you are paying for proximity to institutions that pay very well, keeping the ceiling on prices artificially high. If you are looking for a "starter home," you are likely looking at a fixer-upper condo priced like a luxury mansion elsewhere.
Taxes: The State’s Cut
Massachusetts has a flat state income tax of 5.0%, which sounds reasonable until you realize it applies to every dollar you earn, with very few deductions compared to other states. The real gut punch, however, is property tax. While Cambridge hasn't released a fresh median home price that isn't a ghost number, the tax rate hovers around $6.63 per $1,000 of assessed value. On a conservative assessed value of $800,000 for a modest unit, you are looking at an annual tax bill of roughly $5,304, or $442 a month before you pay a cent of mortgage principal. This is money that provides zero equity and rises with assessments, regardless of your income. If you rent, you are still paying this, just indirectly through your landlord's rent calculation. There is no escaping the tax man in Cambridge; he just lives in a different zip code.
Groceries & Gas: The Baseline Bleed
Groceries in Cambridge are a wallet-drain. You are paying a premium for the convenience of dense urban living and the "Whole Foods effect." Expect to pay 15-20% above the national baseline for staples like milk, eggs, and bread. A standard run for a single person can easily hit $120, whereas that same cart might cost $85 in a suburban supermarket. Gas is equally punishing. The state has some of the highest fuel taxes in the country, and local stations leverage the high cost of doing business to keep prices hovering around $3.40 - $3.60 per gallon. If you commute, you aren't just burning fuel; you are burning cash at a rate significantly higher than the national average. The lack of "cheap" options means you are constantly nickel-and-dimed for basic survival needs.
