IRS SOI migration 2022-2023 recorded 8,431 tax-return households moving from the Boston market area to the New York market area, represented by 9,913 exemptions, a people proxy. That corridor accounted for about 9.18% of Boston’s outbound returns and 4.61% of New York’s inbound returns. Average adjusted gross income was $107,539.68 per return. This establishes a measured tax-filer corridor, not a renter count: IRS flow does not identify renters, every mover or future housing demand.
At the household level, Zillow ZORI asking rents for June 2026 were $3,210 in Boston and $3,573 in New York. The destination difference was $363 a month, or $4,356 annually. That is the clearest immediate change for a renter shopping near each metro-wide asking-rent benchmark, but it is not a quote for a particular unit. The ACS 2024 five-year metro median household income benchmark is also lower in New York, so the higher asking rent should be tested against the mover’s actual pay, household size, concessions, utilities and commute needs.
For rental-property underwriting, Zillow ZHVI for June 2026 placed New York’s typical home value at $735,003 versus $746,595 in Boston. New York consequently shows the higher metro gross-yield screen, 5.83% versus 5.16%. That direction is favorable to top-line income relative to market value, but gross yield is not a property return and does not resolve taxes, insurance, vacancy, maintenance, financing or local rent rules. The next underwriting question is: after those building-specific costs and realistic effective rent, what net operating income remains at the actual property?
