Everyone who works for the City of Boston HAS TO live within the city. Here's how you can OWN.
A single person can't afford to own ANYWHERE. But with only 3, sometimes 2 other people within a three family, you can afford to live EVERYWHERE.
City of Boston employees are required to live within city limits. The salaries the City pays do not match what Boston homes cost. This page puts the two side by side, neighborhood by neighborhood, and shows what changes when a three-family building is bought by three households instead of one.
Each row is a neighborhood. "Three-family building" and "One unit of three" columns come straight from our own sales data — what homes actually sold for. The benchmark tiers ($50K, $70K, $85K, $100K) are median salaries for various groups of City of Boston departments, converted into a monthly housing budget of 28% of their income — the level someone earning that salary can safely spend on housing. The colored cells compare the two: if the monthly cost is higher than the salary allows, that group is locked out of buying alone. Once you add co-buyers, the cost per person drops, and in most neighborhoods it drops enough to become affordable.
Monthly total cost comparisons between renting and owning together.
Three households buy the building together and each takes one unit. The monthly figures are what one household pays to own its unit — mortgage, taxes, insurance and repairs at 20% down — divided among the people living in it.
Utilizing the City's Co-Purchasing Program to Afford the Down Payment
I'm actually speechless here, it speaks for itself.
Each household buys one unit and receives one assistance award, capped at 5% of that unit's price. The household must still contribute at least 1.5% of the unit price from its own funds. "Each of two" and "each of three" divide what the household brings among the people living in that unit. Reserves are not part of the down payment — they are savings a lender expects the household to still hold at closing, shown here as six months of that unit's monthly cost.
How a Three-Family Breaks Down
Figures shown for Dorchester, the neighborhood with the deepest three-family sales history in the data, at 20% down.
How We Calculated the Benchmark Ceilings
$50K Benchmark
$1,167/mo
$50,000 × 28% ÷ 12
$70K Benchmark
$1,633/mo
$70,000 × 28% ÷ 12
$85K Benchmark
$1,983/mo
$85,000 × 28% ÷ 12
$100K Benchmark
$2,333/mo
$100,000 × 28% ÷ 12
Median salary figures are per-department medians provided by the City of Boston workforce data. Benchmark labels are rounded reference points ($50K/$70K/$85K/$100K); underlying department medians vary within each group. The 28% is the standard "don't spend more than this on housing" rule lenders use.
