Moving from New York to Philadelphia presents a lower housing-cost frame, but not a simple demand handoff. IRS SOI migration for 2022-2023 recorded 17,010 tax-return households moving along this corridor, associated with 27,695 exemptions, a people proxy. Those returns represented 6.52% of New York’s outbound returns and 22.28% of Philadelphia’s inbound returns. IRS flow means tax-return households; it does not identify renters, every mover or future demand. Average adjusted gross income was $89,284.30 per return, a description of the filing households rather than a tenant-income target.
At the destination, the Zillow ZORI release dated June 30, 2026 shows the metro asking-rent measure moving from $3,573 in New York to $1,928 in Philadelphia. The gap is $1,645 monthly and $19,740 annualized. On the Zillow ZHVI release for the same date, the metro Zillow home-value benchmark moves from $735,003 to $394,762, a $340,241 difference. These are metro benchmarks, not quotes for a particular household or evidence of a rental property’s acquisition or transaction price.
For household planning, Philadelphia therefore offers a lower advertised rent setting and a lower home-value context, alongside lower local income and regional price benchmarks discussed below. For rental-property underwriting, the lower rent and home-value benchmark sit beside an almost unchanged gross-yield screen, plus contrary signals in migration, permitting and modeled hazard exposure. The next underwriting question is property-specific: what stabilized net operating income remains after verified taxes, insurance, utilities, concessions, maintenance, management, capital work and realistic vacancy and collection assumptions?
