What a 5×5 actually costs here.
BOSTON IS THE COHORT'S TIGHTEST-SUPPLY MARKET. Public Storage Southampton St climate-controlled $167/mo standard is the highest rolling rate in this dataset outside the SF Daly City climate-controlled outlier. Somerville $79 online rolls to $105 standard. All sampled units climate-controlled — Boston winters make non-climate impractical.
Why the rate is what it is.
Boston metro storage supply is 0.7 sqft per capita per Yardi — AMONG THE LOWEST IN THE NATION. Yardi flagged Boston as the strongest YoY rent growth in March 2026 at +9.7%. This is the cohort's most-undersupplied metro and pricing power is real.
What the $1-first-month rolls to.
Somerville $79 is online-only; standard $105 is rolling. Boston-proper $167 reflects supply constraint, not promo theatre. Memorial Day promos less aggressive than Sun Belt because demand sustains pricing.
The local use-case mix.
Apartment overflow dominates (Boston apartments are tiny; 5x5 is the dominant overflow size), Harvard / MIT / BU college storage (massive summer surge — Storage Scholars specifically targets this market), document storage from financial-services concentration in Back Bay.
Operator: Public Storage (Southampton St, Somerville, Malden)
All sampled units climate-controlled. Boston has the tightest supply per Yardi (0.7 sqft per capita) and the strongest YoY rent growth in March 2026 (+9.7%).
