The Green Line Premium
The GLX stations have created a measurable two-tier market. Homes within a quarter-mile of a Green Line station are selling for 12-18% more than comparable properties farther from transit. The premium is strongest at:
- •Union Square — New station + commercial rezoning = strongest appreciation in the city at 11.2% YoY
- •Ball Square — Tufts proximity + new station driving first-time buyer demand
- •East Somerville — Assembly Row spillover + Green Line creating a new residential hub
Neighborhood Breakdown
[Davis Square](/neighborhoods/somerville/davis-square) Still Somerville's most expensive neighborhood. The Red Line and established commercial district command a premium. Median SF: $985K. Competition is fierce for anything under $900K.
[Union Square](/neighborhoods/somerville/union-square) The momentum play. The Green Line station opened and immediately validated years of development planning. Bow Market, the growing restaurant scene, and new mixed-use construction have made Union Square the hottest neighborhood in Somerville. Median condo: $650K.
[Assembly Row](/neighborhoods/somerville/assembly-row) New construction dominates. Assembly Row is effectively a purpose-built urban neighborhood with Orange Line access, retail, dining, and waterfront parks. Condos here start at $550K for studios, $700K+ for one-beds. The planned expansion of 2,900-5,700 additional units will add inventory over the next decade.
[Winter Hill](/neighborhoods/somerville/winter-hill) Somerville's best remaining value. No rail station keeps prices 15-20% below Davis Square, but bus access is solid and the hilltop location offers views of the Boston skyline. Median SF: $795K. Investors are active here in the multi-family market.
The Investment Case
Somerville's triple-decker stock remains one of Greater Boston's best rental investments. A two-family in Winter Hill at $850K with two 3-bed units renting at $3,200/month each generates $76,800 in gross annual rent — a 9% gross yield. After expenses, it's cash-flow positive at today's rates. That math doesn't work in Cambridge or Brookline anymore.
Somerville vs. Cambridge
The perennial comparison. Cambridge has lower taxes ($5.92/K vs. $10.98/K), better schools, and the university ecosystem. Somerville has lower prices (40-50% less for comparable units), more multi-family investment inventory, and now comparable transit access. For buyers choosing between the two, budget is usually the deciding factor.
